How to Draw a Coke Bottle Mold in SolidWorks?
Today I'll show you how to create a mold for a coke bottle in SolidWorks. We'll use the Cravity feature in this tutorial. This tool can be very helpful to subtract a shape from another shape. In this case, we'll subtract the shape of a plastic bottle from a solid block (the mold). I will also show you how to Split a model into new parts. I hope you will learn something from my SolidWorks tutorials.
Click here to download the 3D bottle model and Unzip it into your working map.
Open the file Bottle.SLDPRT
Go to: File > New > Open > Bottle. SLDPRT
Now it's time to draw the mold block
Open a new part with model units set to millimeters
Go to: File > New > Part
Create a 2D sketch
Select the Front Plane in the feature tree (menu at the left side) and create a sketch by clicking on the 2D Sketch icon
The display changes so the Front plane faces you.
Draw a Center Rectangle
Go to Tools > Sketch Entities > Center Rectangle or click on the center rectangle icon 
Create a sketch that starts at the Origin. 
Change the dimensions of the rectangle to 100 and 250 mm by clicking on the dimension button 
Create an Extruded Boss/Base
Go to: Insert > Boss/Base > Extrude or click on the Extrude icon 
The Boss-Extrude menu appears
Direction 1 is set to Midplane
Change D1 into 100 mm
Click OK
Save 
the file with the following name: Mold_Block.SLDPRT
Create a new assembly
Go to File > New > Assembly or click on the Assembly icon 
Select the three planes in the feature tree and make them visible by clicking on the glasses.
Insert the Mold_Block
Go to: Insert > Component > Existing Part/Assembly
Click on the 
button.
Select the Mold_Block.SLDPRT in your working map.
Click OK
The Mold_Block is fixed automatically in the assembly.
Insert the Coke bottle
Go to: Insert > Component > Existing Part/Assembly
Click on the button.
Select the Bottle.SLDPRT in your working map.
Place the model of the Bottle next to the Mold_Block as shown in the picture.
Unhide the Planes
Go to View > Planes or click on the Planes icon 
If the planes keep invisible click at the Glasses in the Feature Tree to Unhide the planes as shown in the picture
Place the Bottle inside the Mold_Block
Create a coincident mate
Go to: Insert > Mate
Select the coincident option.
Select the Front Plane of the Mold Block and the Front Plane of the Bottle.
Click OK
Create another coincident mate
Go to: Insert > Mate
Select the coincident option.
Select the Top Plane of the Mold Block and the MIDPLANE of the Bottle.
Click OK
Create another coincident mate
Go to: Insert > Mate
Select the coincident option.
Select the Right Plane of the Mold Block and the Right Plane of the Bottle.
Click OK
The two models are now fully defined.
Use the Section View to check if the Bottle is inside the Mold Block.
Go to View > Display > Section View or click on the Section View button 
Now it's time to subtract the model of the bottle from the Mold Block.
Click at the Mold_Block and click at the Edit Part icon as shown in the picture
You'll get the following warning: "The assembly must be saved to perform this command"
Click at Save and Continue to Save the assembly.
I will show you how the Cavity feature works.
Go to: Insert > Features > Cavity or click on the Cavity icon 
Select the Bottle in the Feature Tree as Design Components.
Click OK
Click at the Edit Part button in the upper right corner to close the Part mode.
Now I will show you how to split the Mold into two parts:
Draw a Split line
Select the Right Plane in the feature tree and create a sketch by clicking on the 2D Sketch icon
Draw a vertical line as shown in the picture
Click at the Sketch button in the upper right corner to close the 2D Sketch
Go to Insert > Features > Split or click on the Split icon 
Select Sketch2 as Trim Tool and click on Cut Part
Select Part 1 and Part 2 in the Resulting Bodies tab and change the names of the parts
Click OK
You're done! 🙂
