Technical Field

[0001] The utility model relates to the technical field of thermoplastic molding devices for suction cups, in particular to a thermoplastic material molding device for producing high-viscosity suction cups. Background Art

[0002] During the production process of high-viscosity suction cups, thermoplastic rubber is often used as the main material. For the processing of such suction cups, hot pressing molds are often required for molding and hot pressing. Thermoplastic rubber is a special plastic material that softens and flows when heated, and hardens and maintains its shape after cooling. It has properties similar to thermosetting rubber, but can be reshaped after heating.

[0003] During the processing, since the hot pressing process needs to be heated to a certain temperature to ensure that the rubber has the corresponding fluidity, when demolding, manual demolding requires a certain cooling time to ensure safety, otherwise there will be a risk of hand burns. Therefore, it is necessary to design a mechanical demolding structure to ensure rapid demolding and improve safety. Utility Model Content
