Problems solved by technology

[0005] The existing patent CN201800211U discloses an internally threaded plastic mold with an air-cooled core, which can directly cool the internally threaded core through the flow of gas by introducing compressed air into the internally threaded core. The compressed gas is composed of indoor air, so the temperature of the compressed gas is the indoor temperature. Although the water cooling is replaced to reduce the cost, the actual cooling time is longer than the water cooling time. The cooling time of the product in the plastic machine becomes longer and it is easy to use The product has quality problems of shrinkage and deformation, resulting in a high rate of defective products

Abstract

The invention discloses an internal thread mold which comprises a driving structure, the driving structure is connected with a gear assembly, the gear assembly is provided with a rotary mold core, the rotary mold core is connected with a cooling separation device, the cooling separation device is provided with an air inlet, and air enters the cooling separation device from the air inlet to be cooled, so that the cooled air cools the rotary mold core. According to the internal thread mold provided by the invention, by designing the cooling and separating device, external normal-temperature air is cooled through the cooling and separating device and flows into the rotary mold core to cool the rotary mold core, so that a product can be cooled and molded more quickly, and the production quality of the product is improved.

Description

technical field [0001] The invention belongs to the technical field of molds, and particularly relates to an internal thread mold. Background technique [0002] In the prior art, the threaded core is in a state of revolving rotational motion during operation (de-moulding). In the current internal thread mold, the self-rotating thread core is commonly used for internal thread demoulding, and the thread core is driven by an oil cylinder or an oil (electric) motor through a gear. [0003] Since the water pipes of the cooling water will be entangled during rotation, it will cause various inconveniences during continuous production; at the same time, because it is difficult to achieve effective sealing between the rotating thread core and the water pipe, it is very easy to leak water, which will lead to mold rust and There are security risks. [0004] For the above reasons, the rotating threaded core cannot be directly connected to the inlet and outlet of the cooling water pipe...
