20L Bucket Mould Manufacturers introduces the key points of mold design:

1. Review items before design: mold material, molded product, molding machine selection, basic structure of mold base.

2. Important items of mold design: multi-color injection combination method, runner system (low injection pressure; quick filling can increase output; uniform injection, better product quality; reduce waste and shorten injection time.) Molding equipment ( The injection volume of each injection cylinder determines which one is used for the color; the position and stroke of the striker; the configuration of the water circuit, oil circuit, and circuit on the rotating disk; the load-bearing weight of the rotating disk.)

3. Mold base design: mold core configuration design, first consider that the male mold side of the mold must be rotated 180 degrees, and the mold core must be arranged in cross-symmetrical arrangement, otherwise the mold cannot be closed for molding.

①Guide post: It has the function of guiding male and female molds. Concentricity must be maintained in multi-color molds.

②Return pin: Since the mold must be rotated, the ejector plate must be fixed, and a spring is added to the return pin to keep the ejector plate stable.

③Positioning block: to ensure that the two mold bases are fixed to the large solid plate without deviation due to the gap of the screws.

④Adjustment block (wear-resistant block): It is mainly used for adjustment when the mold height z coordinate value is incorrect when the mold is closed.

⑤ Ejection mechanism: The design of ejection method is the same as that of general molds.

⑥ Cooling circuit design: The cooling circuit design of mold one and mold two should be the same as possible.
