Cup injection mold

Abstract

The invention discloses a cup injection mold. The cup injection mold comprises a base; a female mold body is fixedly connected to the center of the top of the base; four groups of supporting rods arefixedly connected to the top of the base; a top plate is fixedly connected to the tops of the supporting rods; a hydraulic cylinder is fixedly connected to the bottom of the top plate; a hydraulic telescopic rod is connected to the hydraulic cylinder; a positioning plate is fixedly connected to the bottom end of the hydraulic telescopic rod; a cavity is formed in the positioning plate; springs areconnected to the top wall of the cavity and abut against a damping ring; a male mold body is fixedly connected to the bottom of the positioning plate; a feeding pipe penetrates through the positioning plate; and the bottom end of the feeding pipe is located between the damping ring and the male mold body. The cup injection mold has the advantages of being simple in structure, capable of effectively damping the mold, low in cost and good in damping effect, in addition, the hydraulic telescopic rod can telescope to drive the male mold body to move, and therefore the mold can be taken very conveniently.

Description

technical field [0001] The invention relates to the field of injection molds, in particular to a cup injection mold. Background technique [0002] Injection mold is a tool for producing plastic products; it is also a tool for giving plastic products complete structure and precise dimensions. Injection molding is a processing method used in the mass production of certain complex-shaped parts. Specifically, it refers to injecting the heated and melted plastic into the mold cavity under high pressure from the injection molding machine, and after cooling and solidifying, a molded product is obtained. Cups are produced with injection molds, but when traditional cup injection molds are used, due to excessive pressure, the mold may be deformed and the quality of the product will be affected. Although some molds are equipped with shock absorption measures, the cost is relatively high. High, and the shock absorption effect is average. At the same time, the traditional mold takes a ...

Cups are produced with injection molds, but when traditional cup injection molds are used, due to excessive pressure, the mold may be deformed, which will affect the quality of the product. Although some molds are equipped with shock absorption measures, the cost is relatively high. High, and the shock absorption effect is average, at the same time, the traditional mold takes a long time to take the mold, and the work efficiency is low
