The injection mold consists of two parts, the movable mold and the fixed mold. The movable mold is installed on the movable template of the injection machine, and the fixed mold is installed on the fixed template of the injection machine. Before injection, the movable and fixed molds are closed under the drive of the injection machine to form a mold. Cavity and gating system, the injection machine injects the plasticized plastic melt into the cavity through the gating system, after cooling and solidification, the movable and fixed molds are opened, and the demoulding mechanism pushes out the plastic to complete the injection molding action of a workpiece.
现有技术中的模具的主要成型机构为型芯和型腔,现有技术中的型芯和型腔可分为整体式和嵌入式等样式,整体式即为型芯或型腔直接加工成型,其结构稳定性高,但是成本较高,加工不便,对于一些成型要求较高的型芯型腔,其材料成本也较高。嵌入式型芯型腔即采用分体式型芯型腔加工完成后嵌入型芯或型腔壳体内,由于采用分体式,型芯和型腔加工方便,其材料也可选用较为优质的材料,成本较低。现有技术中,型芯和型腔闭合后向模具内注射塑料,待成型后打开型芯型腔,由于结构规整,型芯和型腔的分型面大多为平面,即使不是平面,型芯和型腔的合模位置也为平面,因此制作简单方便,而对于一些呈斜面的塑料件。由于其结构整体呈倾斜状,若型芯和型腔仍做成平面,则模具占用空间大,材料成本高,并且质量大,影响加工。The main molding mechanism of the mold in the prior art is the core and the cavity. The core and the cavity in the prior art can be divided into integral type and embedded type. The integral type is the direct processing of the core or cavity. , its structural stability is high, but its cost is high, and its processing is inconvenient. For some core cavities with high molding requirements, its material cost is also high. The embedded core cavity means that the split core cavity is processed and then embedded in the core or cavity shell. Due to the split type, the core and cavity are easy to process, and the materials can also be selected from relatively high-quality materials. lower. In the prior art, plastic is injected into the mold after the core and cavity are closed, and the core cavity is opened after molding. Due to the regular structure, the parting surfaces of the core and cavity are mostly flat, even if they are not flat, the core The mold closing position with the cavity is also a plane, so the production is simple and convenient, and for some plastic parts that are inclined. Because the overall structure is inclined, if the core and the cavity are still made into a plane, the mold will take up a lot of space, the material cost is high, and the quality is large, which will affect the processing.
