Problems solved by technology

A general injection mold is composed of an upper mold and a lower mold. There is a gap between the upper mold and the lower mold. In order to prevent material leakage in the gap, bolts must be used to fasten the connection between the upper mold and the lower mold. However, in actual operation, Due to the limitation of the manufacturing process and the insufficient fastening of the staff, there are still frequent gaps and excessive material leakage, resulting in unqualified plastic products

Embodiment Construction

[0027] The present invention is further described in conjunction with the following examples.

[0028] See eg Figure 1-10 A heat utilization compression type injection mold shown includes:

[0029] The upper mold 1 and the lower mold 2 are covered with each other, and the upper mold 1 and the lower mold 2 are fastened by bolts 3;

[0030] The transmission assembly is used to convert the vertical displacement of the bolt 3 into the horizontal displacement of the force plate 4, and then insert the force plate 4 into the socket 6 of the insert plate 5;

[0031] The reminder component uses the principle of infrared induction to report to the staff the situation that the bolt 3 is fastened in place and the force plate 4 is inserted in place through a reminder light 7 on each side;

[0032] The medium circulation component uses the heat transfer of the mold to use the heat of the injection plastic to heat the liquid water in the liquid storage space 8 at the bottom. The liquid wa...

Abstract

The invention discloses a heat utilization compression type injection mold. The heat utilization compression type injection mold comprises a transmission assembly, a prompt assembly, a medium circulation assembly and a compression assembly; part of heat in the cooling process is converted into compression force between an upper die and a lower die, so that the material leaking quantity of the injection mold is reduced, and the heat utilization rate is effectively increased; and the injection mold has a meaningful impact on an injection molding process.

Description

technical field [0001] The invention relates to the field of injection molding, in particular to a heat utilization compression type injection mold. Background technique [0002] Injection mold refers to a tool that injects hot-melt plastic into the injection cavity, and obtains an injection molded part that is consistent with the shape of the injection cavity after cooling. A general injection mold is composed of an upper mold and a lower mold. There is a gap between the upper mold and the lower mold. In order to prevent material leakage in the gap, bolts must be used to fasten the connection between the upper mold and the lower mold. However, in actual operation, Due to the limitations of the manufacturing process and the insufficient fastening of the staff, there are still frequent gaps and excessive material leakage, resulting in unqualified plastic products. Especially for medium and high temperature injection molding materials, the higher the temperature, the stronger...
