Description

Technical Field

[0001] The utility model relates to the technical field of toy production, in particular to a mold which is convenient for regulating the temperatures of upper and lower molds. Background Art

[0002] Plastic is used as raw material for the production of plastic toys and other items. Plastic molds are used in the production of plastic toys for injection molding.

[0003] Plastic molds are tools used in the plastic processing industry to match plastic molding machines and give plastic products complete configurations and precise dimensions. Due to the wide variety of plastics and processing methods, and the varying structures of plastic molding machines and plastic products, there are also many types and structures of plastic molds.

[0004] When using plastic molds to perform injection molding of plastic toys, the mold needs to be heated during the injection molding process to ensure that the raw materials are melted in the mold so that the raw materials can be filled in the mold in a liquid state. Then, after the injection molding is completed, the temperature is lowered to allow the raw materials to solidify into the desired finished product. Therefore, the temperature of the mold needs to be regulated during this process. Conventional mold temperature regulation is mostly achieved through water, that is, hot water is introduced for heating when the raw materials are injected, and cold water is introduced for cooling after the injection is completed. However, in such an operation, since water is injected from one end of the mold and sent out from the other end, the water that enters the mold first will change in temperature after contacting the mold, thereby affecting the effect on the remaining parts of the mold, thereby causing the efficiency of plastic injection molding production.
