Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to an injection mold which is convenient for fine-tuning an upper mold. Background Art

[0002] Injection mold is a tool for producing plastic products; it is also a tool that gives plastic products a complete structure and precise size; injection molding is a processing method used in mass production of certain parts with complex shapes; specifically, the heated and melted plastic is injected into the mold cavity by the injection molding machine under high pressure, and after cooling and solidification, a molded product is obtained. Although the structure of the mold may vary due to the different types and properties of plastics, the shape and structure of plastic products, and the type of injection molding machine, the basic structure is the same. However, during use, users often need to fine-tune the mold core in order to better perform the injection molding work. However, the existing injection molds have some shortcomings, such as:

[0003] Publication No.: CN115106440A is a stamping die with a fine-tunable die punch. The device can adjust the longitudinal position and relative height of the punch rod. At the same time, each punch rod corresponds to a separate height component, so it can be adjusted independently, and the translation component can drive all the punch rods to move synchronously, thereby having the advantage of overall adjustment. However, in actual use, since the device adjusts the upper module through the support rod rotary column and the gear, the device may produce slight errors during the fine-tuning process, which may cause injection failure;

[0004] Therefore, we propose an injection mold which is convenient for fine-tuning the upper mold in order to solve the above-mentioned problems. Utility Model Content
