Description

Technical Field

[0001] The utility model relates to a hot stamping machine for plastic products, belonging to the technical field of hot stamping of plastic products. Background Art

[0002] Plastic products are a general term for daily and industrial products made of plastic as the main raw material, including products made from injection molding, blister molding and other processes using plastic as the raw material. Plastic is a type of synthetic polymer material with plasticity. Hot stamping of plastic products refers to the process of hot stamping text and patterns of materials such as colored foil on the surface of plastic products, or embossing various convex and concave names or patterns by hot pressing.

[0003] The existing patent number is CN220198814U, which is a hot stamping machine for plastic products. This device places a cylindrical plastic product on the surface of a fixed sleeve. At this time, the limit plate abuts against the inner wall of the plastic product under the action of the spring elastic force, so that plastic products of different diameters can be fixed; after the hot stamping of the plastic product is completed, the sliding rod can be pulled, and the sliding rod will drive the cross rod to push the plastic product to move out of the fixed sleeve. The operator does not need to pull the plastic product to release the high-temperature part of the hot stamping machine and cause safety hazards. However, the method of supporting the cylindrical plastic on the outside through the elastic action of the spring during use is not stable enough, and it is easy to loosen during the hot stamping process, causing the plastic product to tilt or fall, thereby affecting the hot stamping quality; and when this device is in use, after hot stamping a single plastic product, the hot stamped plastic product needs to be removed and a new plastic product needs to be installed before hot stamping can be performed again, wasting a lot of time in the disassembly and assembly process, thereby reducing the hot stamping processing efficiency of plastic products.
