The product has a simple shape, without any reverse buckles or punctures, similar to a cup. The surface of the product is more than 3 degrees, and can be designed as edge gas, oblique gas, valve, etc.
The height of the ribs on the stripper board is less than 1mm. In order to process this rib position, the stripper board can be embedded.
Design method for multi cavity mode:
1. Independent self-locking: Multi cavity independent self-locking is suitable for the design of thin-walled molds of all shapes, with each cavity independent. The locking surface at the bottom of the core is planted into the core composite plate.
2. Integrated locking mold: The wall thickness is greater than 0.8mm, and the machine is relatively small, making it difficult to place. It adopts an integrated structure, but it must be explained in advance.
4, Design of cavity and core structure:
1. The cavity cladding is generally made of P20 steel.
2. The bottom of the single cavity barrel structure cavity is empty, and it is necessary to ensure that the press plate has steel material with a height of 45mm or more. Prevent the production of burrs in the cavity.
3. Insert blocks are used along the cavity edge to reduce cracking of thin steel materials in the cavity.
4. Insert a water jacket into the gate to reduce the cooling time of the hot runner.
