[0001] The utility model relates to the technical field of mold components, in particular to a high-precision molding mold component. Background Art

[0002] Molds are various molds and tools used in industrial production to obtain the desired products through methods such as injection molding, blow molding, extrusion, die casting or forging, smelting, and stamping. In short, molds are tools used to make molded objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the object's shape by changing the physical state of the molded material. The mold assembly refers to the various parts that make up the mold. Through the cooperation of various parts, the mold can ensure that the mold can complete the molding of plastic products efficiently and accurately. In order to improve the efficiency of material processing, a mold assembly is needed. However, the existing mold assembly still has the following shortcomings:

[0003] For example, the utility model with publication number CN209141310U discloses a mold assembly, which has a simple structure and low production cost. It can effectively avoid scratching the insert or generating powder due to scratching during positioning, and is easy to use. However, similar to the comparative documents of the above-mentioned application, when the existing mold assembly is used, since most mold assemblies do not have a stable limiting structure, the mold is easily displaced during the docking process, thereby affecting the subsequent processing yield of the material, resulting in reduced practicality of the mold assembly and reduced utilization efficiency.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a high-precision molding die assembly is proposed. Utility Model Content

[0010] Furthermore, the shock-absorbing assembly includes a lower mold, a mounting groove, a spring damping rod, a receiving block and a limit block. The lower mold is provided with mounting grooves on both sides, and a spring damping rod is installed inside the mounting groove, and a receiving block is installed at the upper end of the spring damping rod, and limit blocks are added at both ends of the outside of the receiving block.

[0011] Furthermore, the shock-absorbing assembly also includes a limiting through hole, a limiting vertical rod, an upper mold and a docking block. A limiting through hole is opened in the middle end of the limiting block, and the limiting vertical rod is connected to the inside of the limiting through hole.

[0014] The utility model provides a high-precision molding die assembly, which has the following beneficial effects:

[0015] 1.

Therefore, the stability of the pressure plate during movement is increased by cooperating with the limiting grooves and the limiting rods, and the position deviation of the pressure plate during movement is avoided by cooperating with the limiting sliders and the limiting slides, thereby improving the accuracy of the mold closing process and increasing the overall use efficiency of the mold assembly.

[0016] 2. The utility model provides a shock-absorbing component.
