Description

Technical Field

[0001] The utility model relates to the technical field of plastic product molds, in particular to a plastic product processing and molding mold. Background Art

[0002] Thermoforming plastic products requires the use of a mold assembly. This assembly is generally divided into a fixed mold and a movable mold. To manufacture a plastic product, the movable and fixed molds are first assembled together. Molten plastic material is then injected into the mold cavity formed by the movable and fixed molds through an injection port. After the molten plastic cools and solidifies, the movable and fixed molds are separated to produce the plastic product. The mold assembly is also equipped with a purification mechanism to process gases during the hot pressing process.

[0003] Although it can process the gas during the hot pressing process, its exhaust pipe is fixed in the box, so it can only exhaust and purify the air at one position in the box, which may cause the air purification effect at other positions inside the box to deteriorate. Utility Model Content
