背景技术Background technique
模具,工业生产上用以注塑、吹塑、挤出、压铸或锻压成型、冶炼、冲压等方法得到所需产品的各种模子和工具,简而言之,模具是用来制作成型物品的工具,这种工具由各种零件构成,不同的模具由不同的零件构成,它主要通过所成型材料物理状态的改变来实现物品外形的加工;目前市场上的模具顶出结构,大多为一次性顶出,但面对产品的胶位面不在同一平面时,一次性顶出导出产品受力不均匀,相对较高的胶位较难脱落,若较低的胶位此时受力不均匀则会导致产品的变形或损坏,造成成品的美观性和原材料的浪费,并且残留的胶粘在模仁上,需要操作员清洗模仁,才能再次投入生产,影响生产的效率;为此提出一种具有二次顶出的电脑壳体模具。Molds, various molds and tools used in industrial production to obtain the desired products by injection molding, blow molding, extrusion, die casting or forging, smelting, stamping, etc. In short, molds are tools used to make molded articles , This kind of tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the article by changing the physical state of the molded material; most of the mold ejection structures on the market are one-time ejectors. However, when the glue surface facing the product is not on the same plane, the force of the product is uneven when the product is ejected at one time, and the relatively high glue position is difficult to fall off. It leads to the deformation or damage of the product, resulting in the aesthetics of the finished product and the waste of raw materials, and the residual glue sticks to the mold core, which requires the operator to clean the mold core before it can be put into production again, which affects the production efficiency. Computer shell mold for secondary ejection.
