The design of the mold will be divided into 2 stages:
1) Preliminary Drawings
The preliminary design is to be submitted within 1 week after receipt of purchase order. The purpose of this design is to determine the general layout and working of the tool to a degree that will allow steel to be purchased.
This stage should include :
- Runner system
- Basic position of water lines
- Clamp slots
- Gate locations
- Gate size
- Support/Pillar locations
- Overall size of the mold
- and any conditions special to the mold.
Project engineer approval is necessary for this stage.
2) Final Design
Drawings are to be fully detailed as follows:
- Details of final gate designs, runner style, layout and style of sprue puller must be shown.
- Complete CAD files of the tools to be submitted. ( 2D and 3D)
- Cores, cavities, inserts or any other part of the mold which are not standard are to be fully detailed.
- Assembly view should be stated the approximate weight of both mold halves.
- A material list is required.
- Detailed drawings are required for all inserts, slides, lifters, etc., with steel hardness specified.
To summarize, in the mold design process some general requirements have to be considered:
– Tool Design
– Mold Bases
– Mold Makers Responsibilities
– Mold Venting Requirements
– Mold Cooling Requirements
– Core Pulls/ Lifters
– Electrical Systems
– Hydraulic Systems
– Finish Requirements
– Mold Identifications
– Mold Try-Out
– Tool Design Checklist
– Tool Sign-off
