Flip-flow screen mold with variable screen holes

Abstract

The invention discloses a flip-flow screen mold with variable screen holes, and belongs to the technical field of molds. The flip-flow screen mold comprises a top seat, wherein a motor is fixedly mounted in the top seat; the output end of the motor is fixedly connected with the input end of a screw rod; the outer side of the screw rod is sleeved with a threaded bearing sleeve; a mold is fixedly connected below the top seat; the mold is fixedly connected with the surface of a base; the two ends of the mold are fixedly connected with sliding rods; the sliding rods are slidably connected into sliding chutes; the sliding chutes are formed in the two sides of the base; inner grooves are formed in the sliding chutes; springs are connected into the inner grooves in an embedding manner; connectingrods are fixedly connected above the springs; the top ends of the connecting rods are fixedly connected to the bottom ends of the sliding rods; and a cooling cavity is formed in the base. By means ofa mounted stripping structure, the mold can be popped up after being formed, and a model in the mold can be rapidly taken out, so that the using effect can be improved.

Description

technical field [0001] The invention relates to the technical field of moulds, in particular to a variable sieve opening type relaxation sieve mold. Background technique [0002] The cavity mold is also called the concave mold, which is the working part of the outer surface of the plastic part. According to its structure, it can be divided into two types: integral type and combined type. It is a mold term in the manufacturing industry. The parts that make up the product space are called molding parts (that is, the mold as a whole), and the parts that shape the outer surface of the product are called cavity molds. [0003] Patent No. CN208558167U discloses a multi-cavity mould, the main points of its technical scheme include an upper mold and a lower mold, the upper mold and the lower mold are provided with a cavity, the upper mold is provided with a sprue, and the pouring A sprue is communicated between the mouth and the cavity, and the sprue includes a main sprue connected...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned multi-cavity mold has the following disadvantages when in use: 1. The above-mentioned multi-cavity mold cannot quickly demould the molded model during use, which makes the demoulding of the model more troublesome

[0005] 2. The above-mentioned multi-cavity mold cannot achieve the effect of fast mold fixing when it is used, which makes the molding time of the mold longer
