Description

Technical Field

[0001] The present application relates to the field of injection molds, and in particular to a quick-release injection mold for a cigarette case. Background Art

[0002] First of all, the working principle of the injection mold is to melt the plastic raw material at high temperature, then inject it into the mold cavity under high pressure, and then cool and open the mold to obtain the final plastic product. However, the overall cavity structure of the mold makes it difficult to completely remove the air inside the cavity. This will lead to a series of problems, such as product flash (i.e. burrs or excess parts on the edge of the product), trapped air, defects caused by the inability to smoothly discharge the air inside the mold, lack of glue, insufficient plastic filling in certain parts of the product, etc.

[0003] In terms of mold structure, complex product structures require that some structural parts of the mold be designed to be relatively thin, which will lead to insufficient strength. When the workpiece is subjected to high pressure or frequent use, its insufficient strength may cause damage, which in turn increases the frequency of mold repair and increases production costs.

[0004] In the mold design process, the traditional approach is to directly use the product as the basis and obtain the mold cavity through difference calculation. Subsequently, the shape is processed by a grinder, and the forming part is completely completed by electrical discharge machining. The disadvantage of this method is that the product has poor exhaust and is prone to flash, which requires manual subsequent processing. In addition, the electrical discharge machining accuracy of the butt-to-butt structure is lower than that of the grinder, so the workpiece is easily damaged. Once the workpiece is damaged, it is difficult to repair, and it usually needs to be repaired by spot welding the entire workpiece and re-discharging. Summary of the invention
