specific Embodiment approach
[0051] In order to further explain the present invention better, the specific embodiments of noise reduction in the present invention are as follows:
[0052] see Figure 1-11 , the injection pipe 73 is used for external pressure equipment to inject injection liquid, which is divided into each sub-runner 72 through the main channel 71, and the injection liquid is injected into the mold cavity through the sub-runner 72, and the injection liquid is cooled and formed in the mold cavity. The injection liquid squeezes the space inside the cavity, and the gas inside is discharged along the exhaust plug 74. When the injection liquid is discharged from the exhaust hole 743, it means that the cavity is filled with injection liquid, and the injection of injection liquid can be stopped in time. , and the vent holes 743 are arranged in the shape of a large inner and outer small circular cone. When the upper mold 1 is ejected by cooling and molding, the upper mold 1 can be lifted up smooth...

The invention discloses a high temperature resistant rapid prototyping injection mould, comprising an upper mould, a lower mould and a base, the lower mould is fixedly installed on the base, the upper mould is installed on the lower mould; an upper mould ejection system is installed on the base And the mold ejection system, the bottom end of the upper mold ejection system and the mold ejection system are installed inside the base. The high temperature resistant rapid prototyping injection mold provided by the present invention has fast injection rate of injection liquid, and can observe that the inside of the mold cavity is filled with injection liquid in time, and can stop the injection of injection liquid and conduct cooling in time; Liquid heat exchange, simple structure and high cooling efficiency; overall injection liquid input efficiency is high, cooling speed is fast, and the efficiency of mold injection molding is fully improved.
Description
technical field [0001] The invention relates to the technical field of injection molds, in particular to a high temperature resistant rapid prototyping injection mold. Background technique [0002] Injection mold is a tool for producing plastic products, and it is also a tool for giving plastic products complete structure and precise size. Specifically, hot-melt plastic is injected into the mold cavity, and the molded product is obtained after cooling. However, when the existing injection mold is used There are the following disadvantages: [0003] 1. The injection speed is slow, and the injection state of the hot-melt plastic, that is, the injection liquid, cannot be observed in time, and the injection cannot be stopped in time, resulting in low injection efficiency and inability to cool in time, resulting in reduced processing efficiency. [0004] 2. In order to speed up the cooling efficiency of the hot-melt plastic and the injection liquid, a complicated cooling liquid ...
