General mold configuration.Since the mold manufacturing belongs to a single-piece small batch production, the repairing method and the adjustment method are generally used in the assembly process to ensure the assembly precision. Next, I will briefly introduce you to the general mold configuration. Our company has extensive experience in this aspect of die. The assembly of the die is mainly to ensure that the punch and the die are aligned to make the gap uniform.
For this purpose, the assembly sequence of the upper and lower molds must be carefully considered before final assembly. Usually, which part of the main part of the upper and lower molds is subjected to a large limit, it is installed as a reference piece, and then it is used to adjust the position of the other part. Generally, the assembly sequence of the die is as follows: 1. The die without the guiding device: Since the gap between the punch injection moulding manufacturers and the die is adjusted by mounting the die on the machine tool, the assembly order of the upper and lower die is not strictly required, and the upper and lower die can be pressed up and down.
The molds are assembled separately. Second, the composite mold with guide column: For the composite mold with guide column, generally the upper mold is installed first, and then the punching punch and the blanking die hole of the upper mold are used to find the position of the convex and concave mold of the lower mold and adjust the gap. , fasten the lower die. 3. Die with guide: Before the assembly, select the reference part, such as guide, punch, die or concave mold. When assembling, first assemble the relevant parts according to the reference piece, then adjust the clearance between the convex and concave molds to ensure uniform clearance, and then install other auxiliary parts.
If the die is mounted on the lower die, it is generally convenient to install the die first, and then the lower die is used as a reference for mounting the die. 4. The working parts of the upper and lower molds are respectively guided into the guide column molds of the upper and lower template sockets: at this time, according to the requirements of the drawings, the working parts are placed in the upper and lower template sockets, respectively, on the coordinate trampoline. The cutting edge of the upper and lower die working parts is the reference piece, the guide post and the guide sleeve hole of the upper and lower die bases. 5. Continuous die with guide post: In order to facilitate the adjustment of the accurate step distance, the die block should be loaded into the lower die after assembly, and then the lower die part should be installed based on the die.
