Description

Technical Field

[0001] The utility model relates to the technical field of heat dissipation of injection molds, in particular to a built-in detachable heat dissipation structure of an injection mold. Background Art

[0002] Injection molds are manufacturing tools used for mass production of plastic products. They manufacture parts of various shapes and sizes by injecting molten plastic into the mold cavity and cooling it to form a mold. Injection molds are usually composed of multiple parts, including main channels, branch channels, gates, mold cavities, etc. These parts together constitute a complete mold, and each part has its specific function.

[0003] During the injection molding process, molten plastic is injected into the mold cavity under high pressure. The plastic cools and solidifies in the mold cavity to form the desired product shape. After that, the mold opens, the ejection system ejects the finished product, and then the mold closes to prepare for the next injection.

[0004] During the cooling and curing process, in order to increase the cooling speed, a heat dissipation cooling structure is often added. For example, the utility model with application number 202121711535.1 proposes an injection mold heat dissipation mechanism that can dissipate heat through air cooling.

[0005] However, current heat dissipation structures are generally external, so the heat dissipation effect is poor, which brings inconvenience to users. Alternatively, the heat dissipation structure directly extends into the mold, but its structure is fixed, which is not easy to connect and fix, and is not convenient for subsequent disassembly and assembly.
