Technical Field
[0001] The invention relates to the field of molding dies, and in particular to a product compression molding die with multiple inserts. Background Art
[0002] A compression molding mold, also known as a compression mold, is a device that can directly add plastic raw materials into an open mold cavity, close the mold, and allow the plastic raw materials to melt and flow rapidly under the action of heat and pressure, filling the mold cavity. The raw materials are then chemically cross-linked and physically cooled to harden and shape.
[0003] However, the existing product compression molds must first determine a reasonable mold structure, that is, how these product inserts are fixed in the mold cavity to ensure that the position and size of the product inserts remain unchanged when the plastic melt buries them. At the same time, it is also necessary to consider whether the distribution of the ejection and demolding mechanism is reasonable so that the product inserts are not damaged during the ejection and demolding process, which facilitates product ejection and is easy for compression molding production, and thus has low practicality.
