Based on the analysis of the structure, size and process of large-scale die-casting parts, dcc400 die-casting machine is selected to determine the parting surface of the largest surface of the parts. Four sets of slant guide pillars are used to drive slant slide block to pull core, pull core and push die, and three kinds of inserts are positioned and installed in the die. Because the inner cavity size of the casting is 55 mm larger than the outer cavity size of 45.6 mm, the movable slider mechanism is used to demould and push out the casting together with the mandrel. According to the parting surface to determine the location of the mold parts, and then determine the mold structure and the assembly relationship of the parts.
Its shape is complex, the upper part is semi cylindrical shell, the middle and lower part are rectangular shell. The minimum wall thickness is 5mm and the maximum wall thickness is 12mm. It can be seen from the figure that there are three square holes on the upper part and left and right sides of the casting, which need inclined guide post and inclined sliding core pulling. The lower hole is cored by the moving slide block, the convex shape at the bottom of the casting and the lower hole are cored by the inclined guide post and the inclined slide block. Since there are three blades on the housing assembly, it is necessary to ensure that the blades are positioned and installed reliably and accurately on the mold setting. The insert 1 is mounted on the core 29 that moves in the mold. Insert 2 and insert 3 are composite parts. First install insert 3 on insert 2, and then bend insert 3.
在beplay全站app安卓安装过程中，将insert 2的上水平部分和insert 3的右部分安装在固定模腔上的定位安装孔中。铸件内腔尺寸分别为57.6mm和55.0mm，比外腔尺寸45.6mm大，正常型芯无法脱模。因此，设计了一种用于横向运动的滑动机构来进行消雾。分型面位于右端面结构的f在图1中,和许多端面外凸的形状是由固定死,所以固定模衬是一个大的组成部分,如处理困难或由线切割beplay全站app安卓排气不好可以分解过程。铸件型腔由动模芯和滑块组成。
During the mold installation, the upper horizontal part of insert 2 and the right part of insert 3 are installed in the positioning installation hole on the fixed mold cavity. The inner cavity size of the casting is 57.6mm and 55.0mm respectively, which is larger than the outer cavity size of 45.6mm. The normal core cannot be demoulded. Therefore, a sliding mechanism for lateral motion is designed to eliminate fog. In Figure 1, the parting surface is located in the structure of the right end face, and many of the convex shapes of the end face are fixed, so the fixed die liner is a large part, such as difficult to handle or poor exhaust from the wire cutting die can be decomposed. The casting cavity is composed of a moving die core and a sliding block.
