VISI Mould - Slide Assembly Creation
Objectives
Having now inserted the lifters we will move onto the creation of Slides. The Slides are required to help mould the undercut features on the product and in this particular case we have for slots in the side of the component that will be formed by the moving side cores.
For this task we will begin from the last completed stage of the training and it is required to load the starter file as detailed below. Do not worry if you have not managed to complete the previous training exercises as the starter file will bring you right up to the correct point for this section.
NOTE :- You will require an updated GENERAL.MDB catalogue which is supplied with this training example. It needs to be copied to the path :-
C:\VISI131\LIBRARY\COMMON\PARAM-NG\COMMON|MOULD\DB\GENERAL
¾ Loading the File
Lets begin by opening the file required for this tutorial.
Select the File | Open command and select slide-start.wkf
Vcamtech Co., Ltd 1
¾ Adding Simple Slides to the Design
The next step will involve creating a simple slide to locate within some pre-modelled slide components such as the slide heal, core pins and face plate. We will create the slide using the automatic slide builder.
To make the task of inserting the Slide into the assembly easier, we will again filter the layers selecting only the ones relevant for the task.
¾ Create the pocket to house the slide assembly
Make A Pocket For The Slide Assembly using the Subtract command.
Use the Slide Insertion group to activate the relevant layers.
1. Pick the Target Body as shown here.
2. Pick the Tool Body as shown here. Pre-Modelled Pocket Solid

¾ Create the Slide body
Lets begin to create the slide body. Choose the standard elements option from the Mould drop down menu.
Now pick the Slide icon from the available list of components.
Vcamtech Co., Ltd 3
Select Standard Element from the Mould drop down
Select the SliderCore tab from the General catalogue
Make sure the General catalogue is selected
Select the Slide icon from the General catalogue components.
1.Select the back face of the Face Plate. (Face in selection tree.)
2.Select the bottom face of the Pocket.(Support Face in selection tree)
Pick the Mid Point of the edge shown here as a reference point for the slide positioning in X and Y.(Point in selection tree.)
You will now need to pick a Face, Support Face and a location point for the slide.
¾ Configure the Slide with the parameters shown below. Initially all the values will be set to zero.
Here is a summary of the parameters involved in creating the slide, they can be obtained by clicking the “Display Builder Bit Map” icon.
Initial Settings
“Display Builder Bit Map” icon will reveal the description of the parameter and their meanings.

The Result
Here is what you should expect to see with the Slide in position behind the facing plate.
¾ Adding a Slide Wear Plate beneath the slide body.

Slide shown in position
Select the SliderCore tab from the General catalogue
Make sure the General catalogue is selected
Select the SLDPLATE from the General catalogue
You will now need to pick the Slide where you want to insert the slide plate.
Pick the Slide anywhere on its body.
Now enter the parameters as shown below for the Slide Plate.
The Result
Here is what you should expect to see with the Slide Plate situated below the Slide body.
¾ Adding Guide Rails to the Slide Assembly
Select the General Catalogue > Slider Core
Make sure the Core layer is selected.
Enter the Width, Height and Length as shown opposite.
Slide Plate shown underneath the slide body.
Select the A_SLGUI_SCREW.This
VISI Mould - Slide Assembly Creation
We will need to select the appropriate Slide Body again to begin the insertion process for the Guide Rails.
Insert the parameters as shown below for the Left and Right Side guide rails. (Note:- We will leave the Screw parameters as default but they can be accessed and modified by scrolling down on this dialogue box.)

Pick the Slide anywhere on its body.
These should be the default parameters when you first pick the Slide Body. If not please change them to match those opposite.
Make sure Core layer is the target layer.
Reminder: - When you have configured the parameters select the apply button to insert the component.
The Result
The picture below shows the left and right guide rails inserted into the slide assembly. This is shown using “Transparent Shading”.
¾ Insert Locking Heel into slide Assembly Select the General Catalogue > Slider Core
We will need to select the appropriate Slide Body again to begin the insertion process for the Locking Heel.
Slide Rails shown in position.
Transparent shading used for this display.
Select the A_SLDLOCKHEEL1.This is a Locking Heel assembly with automatic insertion of wear plate and fixing screws.
Pick the Slide anywhere on its body.
Use the scroll bar and drag to the right to locate the Locking Heel icon.

Insert the parameters as shown below for the Locking Heel. (Note:- We will leave the Screw parameters as default but they can be accessed and modified by scrolling down on this dialogue box.)

Insert the parameters for the Locking Heel as shown opposite.
Make sure Core layer is the target layer.
Locking Heel shown in position with transparent shading used to illustrate this.
The Result
The resulting Locking Heel is shown below.
¾ Inserting the Angle Pin
The final part of the Slider Assembly will be the insertion of the Angle Pin used for actuating the slide.
Firstly, activate the layers shown opposite.
Select the Hasco Catalogue and the Slider Core menu tab and pick the Z01_L angle pin from the item list.
It is now necessary to select a Start plate, the Slide , a Point and the Slide Direction.
Activate the Layers as shown here. You should only need to append the CAV layer to the visible list.
Select the Slider Core tab from the Hasco Catalogue menu.
Pick the Z01_L angle pin from the item list.
Pick the Start Plate as shown, this is the Fixed Half Cav plate.
Pick the Slide body as shown, this is the slide that the pin will pass through.
VISI Mould - Slide Assembly Creation Now input the Angle Pin insertion co-ordinates. The pin point is actually 10mm from the centre of the front edge of the slide. This actually translates to a tool co-ordinate position as shown below :-
Now select the Stroke Direction for the slide. This should be a –Y direction, representing the retraction direction of the slide as the tool opens. Shown Below:-
Vcamtech Co., Ltd 11
Insertion point 10mm from centre of front edge of Slide. Absolute ref 0,-105,90
Arrow represents the –Y direction and should point the same way as shown opposite.
This is the Initial Preview after you have confirmed the stroke direction.
Insert the correct parameters for the Angle Pin suitable for our requirements. Configure the parameters to match those shown below: -
Choose a 12mm diameter pin.
Select an 100mm pin length.
The incline angle of the Pin is 8 degrees.
We require a minimum stroke of 1.4mm for the core pin to retract from the part.
By typing in a minimum stroke the system calculates the achievable stroke based on the pin dimensions and angle.
Slot Cavity
The slot cavity is a pocket that can be configured when the angle pin is long enough to pass through the slide and needs relief in the core plate.
Components removed for illustration purposes.
Make sure Core is the selected layer.

¾ Exercise – Create the same Slide Assembly in the other side of the mould tool.
This completes the section on Inserting Standard Elements into the Mould Assembly. In the next stages we will add some cooling channels to the Fixed Half of the tool. To make this process easier and more realistic we will open a more complete version of the Mould Tool that we have already worked on. This tool is almost identical to the one you have produced so far but contains slightly more standard elements.
Vcamtech Co., Ltd 13
Following the previous example, now make an identical slide in the pocket on the opposite side of the tool.
Here is what you should expect with both Slide Assemblies in position.
