The utility model discloses a mould for the upper and lower cover of a computer main engine, which comprises a base, a forming groove, a liquid injection port and a push-pull block. The built-in type of the forming groove is arranged inside the base, the left and right sides of the base are embedded with grooves, the liquid injection port is located inside the block, the block is located between the base and the push-pull block, and the ring nut and the block are connected with the push-pull block. The upper part of the push-pull block is welded with a pull ring. The base of the utility model is a cuboid metal block, and the left and right grooves are symmetrically arranged to ensure that the upper and lower cover moulds of the computer main engine are strong and durable enough, and the length of the chuck is equal to the depth of the groove, so that the connecting parts of the upper and lower cover moulds of the computer main engine are fully tightly connected during the moulding process, and the length of the push rod is equal to the diameter of the injection port and the length of the right side of the joint block. The remaining metal liquid is completely separated from the forming groove. A ring-shaped rotating handle is welded on the top of the ring nut, so that the joint and push-pull block are closely connected.

技术介绍
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,在外力作用下使坯料成为有特定形状和尺寸的制件的工具,广泛用于冲裁、模锻、冷镦、挤压、粉末冶金件压制、压力铸造,以及工程塑料、橡胶、陶瓷等制品的压塑或注塑的成形加工中,模具具有特定的轮廓或内腔形状,应用具有刃口的轮廓形状可以使坯料按轮廓线形状发生分离(冲裁),应用内腔形状可使坯料获得相应的立体形状,模具一般包括动模和定模两个部分,二者可分可合,分开时取出制件,合拢时使坯料注入模具型腔成形,模具是精密工具,形状复杂,承受坯料的胀力,对结构强度、刚度、表面硬度、表面粗糙度和加工精度都有较高要求,模具生产的发展水平是机械制造水平的重要标志之一。现有的模具的形状和内部空腔以及外部设置均具有多种不同的结构,但却具有一些共同的缺点,其一,现有的模具没有设置卡块,而是用螺母紧固的方式将两片模具紧固,导致模具的紧密度不够,造成模具的制作失败,其二,现有的模具没有设置推杆,导致多余的金属液无法与成 ...
