Problems solved by technology
Due to the large number of action steps, the time period for a plate from feeding to finished product output is long, the production speed is slow, and it is difficult to increase the production capacity.
At the same time, the realization of multiple actions requires more equipment investment, the structure is relatively complicated, and the cost investment is relatively high
The blister forming station can only be formed at a single station, and cannot carry out continuous production without interruption.

The invention provides a continuous cooling plastic suction mold. A cooling device is designed and installed in a mold barrel similar to a cylinder; the cooling device is connected with the outside through a special structure; a cooling medium is introduced from the special structure; rapid heat exchange is conducted after the forming on the mold barrel, then heat is taken away through a plastic suction pipeline, and therefore the effects of mold barrel cooling and mold surface temperature stabilizing are achieved. By the adoption of the production process of the continuous cooling mold, sheets can be directly subjected to plastic suction shaping and cooling after being extruded out of an extrusion mold; then, intermediate transfer of the plates and a large amount of investment of rear-endprocess equipment are reduced, and the production process is greatly helpful for reducing the cost and the production difficulty.
Description
technical field [0001] The invention relates to a mold cooling system in the production process of thermoplastic continuous blister products, in particular to a continuously cooled blister mold. Background technique [0002] In the production process of blister products, the production process is to heat-melt the sheet into a semi-fluid state, place it on the mold, and then shape the product by means of negative pressure. In the process of blistering, a lot of heat is taken away, so that the surface of the mold is cooled, and then shaped, and the shape on the mold is copied on the sheet. At this time, a large amount of heat will be transferred to the mold, which will increase the temperature of the mold, so that the shape cannot be completely copied, and the demoulding will cause the shape to deform, affecting product quality and efficiency. [0003] Patent application number: 201410015663.0 A plastic-absorbing device and method are widely used in the current plastic-absorb...
