Description

Technical Field

[0001] This utility model belongs to the field of die casting mold frame technology, and in particular relates to a split die casting mold frame. Background Technology

[0002] Die casting mold sets are indispensable components in die casting production. Their main function is to install the mold cavity, core, and other parts, and to ensure accurate mold closing and opening during the die casting process. Traditional die casting mold sets are usually of an integral structure, which has some shortcomings in the manufacturing process.

[0003] Integral molds require the use of large pieces of raw materials for processing. Because the structure of molds is often complex, a significant amount of material needs to be removed during processing, resulting in low material utilization, waste, and increased production costs. Furthermore, integral molds are difficult to process, especially large or complex ones, requiring advanced equipment and resulting in long processing cycles, which hinders production efficiency.

[0004] Therefore, we propose a split die-casting mold base. Utility Model Content

[0005] The purpose of this invention is to provide a split die-casting mold frame to solve existing problems.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a split die-casting mold frame, including a moving mold and a fixed mold that matches the moving mold. Guide grooves are provided on both sides of the lower surface of the moving mold, and guide columns are fixed in the guide grooves.

[0008] The fixed mold consists of a bottom mold and two inserts that are detachably connected by a connector. The bottom mold and the two inserts enclose a cavity for die casting. The bottom mold has positioning grooves on both sides of its upper surface. The bottom surface of the positioning grooves has several locking screw holes. The lower surface of the inserts has positioning blocks that match the positioning grooves. The lower surface of the positioning blocks has several mounting screw holes that correspond one-to-one with the locking screw holes. The inserts are fixedly connected to the bottom mold by passing through the locking screw holes and mounting screw holes in sequence via the connector.

[0009] The upper surface of the insert is provided with a guide block that matches the guide groove, and one surface of the guide block is provided with a guide hole that matches the guide post.

[0010] In one embodiment, the upper surface of the moving mold is fixed with a mounting base plate by bolts, the connecting member is a bolt, and the two inserts are symmetrically arranged.

[0011] In one embodiment, the positioning groove is an "L"-shaped groove, the positioning block is an "L"-shaped protrusion, the position and size of the positioning groove are adapted to the positioning block, and the positioning block and the positioning groove cooperate with each other.

[0012] In one embodiment, the shape and size of the guide block are adapted to the guide groove, and the guide block and the guide groove cooperate with each other.

[0013] In one embodiment, the shape and size of the guide post are adapted to the guide hole, and the guide post and the guide hole cooperate with each other.

[0014] In one embodiment, the shape and size of the moving mold are adapted to the fixed mold, and the moving mold and the fixed mold cooperate with each other.

[0015] This utility model has the following beneficial effects:

[0016] This invention designs the fixed mold as a split structure, consisting of a bottom mold and two inserts that are detachably connected by connectors. Compared with an integral fixed mold, each fixed mold component is smaller in volume, reducing material waste and lowering material costs during processing. The split fixed mold structure also reduces the processing difficulty of each component, eliminating the need for large processing equipment, facilitating manufacturing, shortening the processing cycle, and improving production efficiency. Furthermore, the detachable connection between the fixed mold components allows for individual replacement of any damaged component without replacing the entire fixed mold, thus reducing maintenance costs.

[0017] The positioning structure in this invention ensures the accuracy of the connection between the two parts of the mold and improves the assembly precision of the mold, thereby guaranteeing the quality of the die-cast products.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
