Embodiment 1

[0018] The present invention discloses a quick demoulding plastic mold, comprising: a fixed mold 1 and a movable mold 2, the fixed mold cavity 3 is provided on the side of the fixed mold 1 facing the movable mold 2, and the movable mold 2 faces the movable mold 2 One side of the fixed mold 1 has a movable mold core 4, wherein, there are protrusions 6 on both sides of the fixed mold 1 and the movable mold 2, and the movable mold 2 and the fixed mold 1 are matched. There are grooves 7 on both sides, and the fixed mold 1 and the movable mold 2 are connected and closed through the cooperation of the bump 6 and the groove 7, so that the movable mold core 4 and the fixed mold cavity 3 are matched , and form a mold cavity 5 for accommodating molten rubber.

[0019] The middle part of the movable model core 4 is equipped with a glue injection channel 8 that runs through the movable mold 1. The glue injection channel is a trumpet-shaped structure, and its small-caliber end faces the to...

Abstract

The invention discloses a plastic mold capable of demolding quickly. The plastic mold comprises a fixed mold and a movable mold, a fixed mold cavity is formed in one side, facing the movable mold, ofthe fixed mold, a movable mold core is arranged on one side, facing the fixed mold, of the movable mold, and the movable mold core is matched with the fixed mold cavity to form a mold cavity; a glue injection channel penetrating through the movable mold is installed in the middle of the movable mold core, cooling pipelines are internally arranged in the fixed mold cavity and the movable mold core,and water inlet ends and water outlet ends of the cooling pipelines extend out of the plastic mold. According to the mold, cooling devices are correspondingly arranged on the two sides of the upper surface of the mold cavity, two sides of the lower surface of the mold cavity, and the two sides of the glue injection channel so that residual rubber materials in a whole injection molding and the residual rubber materials in a glue injection port can be cooled at the same time, then the demolding efficiency of the whole injection molding is improved, and particularly, the demolding difficulty atthe glue injection opening is reduced; and by adopting the plastic mold, the demolding speed of the injection molding is high, the demolding performance is reliable, the production efficiency is high,and the practicability is high.

Description

technical field [0001] The invention relates to the field of moulds, in particular to a quick-release plastic mold. Background technique [0002] Mold manufacturing plays an important role in the process of industrial product processing. In plastic processing, it is a common processing method to use plastic molds to form plastic parts. Plastic molds generally include an upper mold base and a lower mold base. The upper mold base and the lower mold base are covered to form a mold cavity, and then liquid wax is injected into the mold cavity to solidify and then forged. [0003] When using plastic molds to prepare plastic products, the ease of demoulding of finished products becomes one of the important factors to control the production efficiency and product quality of plastic parts. Most of the existing plastic molds are only equipped with a cooling device on one side of the lower mold. The finished product is separated from the lower mold cavity through cooling, but for the...
