High-heat-dissipation injection mould

Abstract

The invention discloses a high-heat-dissipation injection mould. The high-heat-dissipation injection mould comprises a male mould body and a female mould body and further comprises a cooling device. The cooling device comprises at least one heat dissipation pipe penetrating through one of the male mould body or the female mould body and a vortex cold air gun. The vortex cold air gun is provided with an air inlet channel, a vortex device, a cold air channel and a hot air channel, wherein the vortex device is used for dividing air entering from the air inlet channel into cold air and hot air, and the cold air channel and the hot air channel communicate with the vortex device and are used for collecting the cold air and the hot air correspondingly. The cold air channel of the vortex cold airgun communicates with one ends of the heat dissipation pipes, and the other ends of the heat dissipation pipes communicate with the outside world. By adopting the structure, the high-heat-dissipationinjection mould has the following advantages that the work efficiency is improved, the heat dissipation effect is good, shrinkage of the rubber thickness can be guaranteed, and the part quality is guaranteed and improved.

Description

technical field [0001] The invention relates to a high heat dissipation injection mold. Background technique [0002] In the injection molding part 1 in the prior art, the difference in the thickness of the glue should not be too large, if it is too large, it will cause uneven shrinkage and cause defects on the surface of the glue, but this will make the thickness of the glue in special parts not too large . But for some special parts 1, such as attached figure 1 and figure 2 As shown in A and B, the thickness of the glue in this part is relatively large, so how to ensure the quality of the finished product is a major technical problem that plagues those skilled in the art. Contents of the invention [0003] The invention provides a high heat dissipation injection mold, which has good heat dissipation performance in the injection molding process to ensure that the part with thick colloid can be formed. [0004] The invention discloses a high heat dissipation injection...
