Description

Technical Field

[0001] The utility model patent relates to the technical field of thermoforming molds, and mainly relates to a cooling mechanism for a thermoforming device. Background Art

[0002] Hot stamping forming is a part processing method. First, the blank is heated to a certain temperature, then the blank is transferred into a preheated mold, and then it is stamped into shape by a stamping device. After stamping, the mold needs to be cooled. The traditional cooling method is to lay cooling pipes on the outer side of the mold, and cooling water is filled into the pipes during cooling. However, there are many types of parts, and the corresponding molds are also various. Setting cooling pipes on the mold itself will result in high costs, and the contact area between the cooling pipes and the mold is relatively small, so the cooling effect is average. For this reason, we propose a cooling mechanism for a thermoforming device. Content of the Utility Model

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] The present utility model provides a cooling mechanism for a thermoforming device. By driving the screw rod to rotate through a rotating motor, the upper mold is driven to descend, so that the upper mold contacts the lower mold to form a product. By driving the sealing block to descend through a communicating pipe, the sealing block closes the water passing hole to prevent the water inside the lower mold from entering the cooling tank. By using a refrigeration pipe to refrigerate the water inside the cooling tank, and by using a water pump to make the cold water in the cooling tank sequentially pass through the upper mold, the lower mold and the cooling tank. By opening the water passing hole, the water inside the lower mold enters the cooling tank, thereby emptying the water inside the upper mold and the lower mold, facilitating the heating of the upper mold and the lower mold by a heating pipe. By the elastic force of a spring, the sealing block closely adheres to the sleeve to prevent the cold air inside the cooling tank from overflowing. This device not only facilitates the cooling of the mold, but also has a low cooling cost, and moreover, it empties the water inside the mold, facilitating the heating of the mold by a heating pipe.
