Technical Requirements for Assembly Drawing of Low-Pressure Casting Mold
1.Mold material :The mold material is chosen carefully according to the physical and chemical properties of the product being molded ,Combination of mold materials with different properties should be considered .
2.Complex shape: The shape of the mold should be as simple as possible and easy to open and close .Otherwise, it will not only increase the production cost ,but also cause problems in the process of assembling and disassembling the mold.
3.Casting design :The shape design of the product to be casted shall be reasonable and easy to mould.The product should be designed symmetrically.The thickness of the wall should be uniform and reasonable.
4.Molding structure:The die shall be designed reasonably and manufacturable .The mould structure shall be considered from the perspective of rigidity, strength and service life .
5.Die Products:The die products can be made of metal or non-metallic material nature ,shape, size, placement and assembly should be reasonable and reliable, process requirements should meet the requirements of drawings.
6.Gears and guide pins :The design criteria for the gears and guide pins shall be reasonable .The smooth running should be fully considered .
7.Assembly of die :The parts should not be disconnected during assembly and disassembly.And the parts should fit tightly and stably after assembly.
8.Overall test :The overall appearance of the die should be tested to see if it meets the design requirements and is suitable for use.Themes such as dimensional accuracy, contour accuracy ,evenness ,and straightness should be tested.
9.Casting :Once the mould is assembled ,we should ensure that it works properly and meets all the requirements of the customer .The casting process should be reasonable and reasonable.
10.Demoulding :The demoulding of the two parts should be smooth and convenient, and it is better to use special tools ,such as demoulding device, to facilitate the demoulding.
11.Locating :The locating machine should be reasonable and reasonable .The mould should be able to locate
accurately and correctly .
12.Lubrication :Good lubrication should be maintained between all moving parts of the mould .This will reduce the wear and tear of the mould .It should be checked regularly to ensure that it is working properly.
13.Maintenance :Regular maintenance of the mould should be carried out and preventive measures should be taken in time .The parts should be replaced when necessary .
14.Mark :The mark of the mould should be clearly marked ,easy to identify and to understand.
By following these technical requirements the production efficiency of low-pressure casting mould can be improved and a high-quality product can be obtained.
