Description

Technical Field

[0001] This utility model relates to the field of die casting machine technology, and more specifically, to a die casting mechanism for a die casting machine with precise alignment. Background Technology

[0002] Die casting machines are commonly used equipment in the forming technology field of the machinery industry. They are industrial machines that inject molten metal into a die casting mold under pressure, cool and solidify it, and obtain a solid metal casting after the mold is opened.

[0003] Currently, in the use of die casting machines on the market, the die casting mechanism consisting of the dynamic die casting mold and the fixed die casting mold is prone to misalignment between the dynamic die casting mold and the fixed die casting mold when die casting the target product. This will cause dimensional deviations or deformations in the die-cast target product, which will affect the quality and pass rate of the die-cast target product. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a die casting mechanism for a die casting machine with precise alignment, which enables the moving die casting mold and the fixed die casting mold to be precisely aligned, thereby avoiding dimensional deviations or deformations in the target product after molding, and thus improving the quality and pass rate of the target product after die casting.

[0005] This utility model provides a die-casting mechanism for a die-casting machine with precise alignment, including a fixed template, a fixed die-casting mold, a moving template, a moving die-casting mold, and four guide pillars distributed circumferentially. The fixed template is fixed on the four guide pillars, and the fixed die-casting mold is fixed in the middle of the inner side of the fixed template. The moving template is slidably connected to the four guide pillars, and the outer side of the moving template is connected to the drive assembly in the die-casting machine. The moving die-casting mold is fixed in the middle of the inner side of the moving template. A wedge block is fixed on the inner end of the moving template and at the middle of each side of the moving template. A wedge groove adapted to the wedge block is provided in the middle of each side of the inner end of the fixed template. When the moving template drives the moving die-casting mold to close the moving die-casting mold with the fixed die-casting mold, each wedge block is inserted into the wedge groove at the corresponding position and fits into the wedge groove.

[0006] By adopting the above-described structure, when the moving template drives the moving die-casting mold to close with the fixed die-casting mold, each wedge block can be inserted into the corresponding wedge groove and fit into it. In other words, under the combined action of all the wedge blocks and wedge grooves, the moving die-casting mold and the fixed die-casting mold can be limited along the circumferential direction of the die-casting mechanism. This allows for precise alignment between the moving die-casting mold and the fixed die-casting mold, thus preventing dimensional deviations or deformations in the molded target product and improving the quality and pass rate of the die-cast target product.

[0007] In one possible implementation, each wedge block has a fixing part on the end facing the dynamic die casting mold, and the dynamic die casting mold has a groove adapted to each fixing part, with each fixing part inserted into the groove at the corresponding position; each fixing part has a countersunk hole perpendicular to the guide post, and each groove has a threaded hole perpendicular to the guide post on its inner sidewall; each wedge block and the dynamic die casting mold are fastened by a bolt passing through the countersunk hole and threadedly connected to the threaded hole; with this structure, after the fixing part and the groove are engaged, the wedge block and the dynamic die casting mold can be limited, and after the bolt thread passes through the countersunk hole and is threadedly connected to the threaded hole, each wedge block can be reliably fixed together with the dynamic die casting mold.

[0008] In one possible implementation, each fixing part has a positioning post on the end facing the dynamic die casting mold, and each groove has a positioning hole on its inner end. Each positioning post is inserted into the positioning hole at the corresponding position, and the outer peripheral wall of each positioning post fits against the inner peripheral wall of the corresponding positioning hole. With this structure, when the fixing part and the groove are engaged, the positioning post can be inserted into the positioning hole to position the fixing part and the groove, which facilitates the process of inserting the fixing part into the groove. After the positioning post and the positioning hole are engaged, the reliability and stability of the fixing part and the dynamic die casting mold after fixing can be improved, that is, the reliability and stability of the wedge block and the dynamic die casting mold after fixing can be improved.

[0009] In one possible implementation, each positioning post has an annular chamfered surface at its outer edge away from the fixing part. The annular chamfered surface is used to guide and cooperate with the hole wall of the positioning hole so that the positioning post can be inserted into the positioning hole at the corresponding position. With this structure, under the action of the annular chamfered surface, when the positioning post is inserted into the positioning hole, the positioning post can cooperate and be guided with the hole wall of the positioning hole so that the positioning post can be inserted into the positioning hole, which can facilitate the insertion of the positioning post into the positioning hole.

[0017] See Figure 1-3 As shown in the embodiment of this application, a die-casting mechanism for a die-casting machine with precise alignment is disclosed, including a fixed template 1, a fixed die-casting mold 2, a moving template 3, a moving die-casting mold 4, and four guide pillars 5 distributed circumferentially. The fixed template 1 is fixed on the four guide pillars 5, and the fixed die-casting mold 2 is fixed in the middle of the inner side of the fixed template 1. The moving template 3 is slidably connected to the four guide pillars 5, and the outer side of the moving template 3 is connected to the drive assembly 6 in the die-casting machine. The moving die-casting mold 4 is fixed in the middle of the inner side of the moving template 3. A wedge block 7 is fixed on the inner end of the moving template 3 and in the middle of each side of the moving template 3. A wedge groove 11 adapted to the wedge block 7 is provided in the middle of each side of the inner end of the fixed template 1. When the moving template 3 drives the moving die-casting mold 4 to move so that the moving die-casting mold 4 closes with the fixed die-casting mold 2, each wedge block 7 is inserted into the wedge groove 11 at the corresponding position and fits into the wedge groove 11.

[0018] Each wedge 7 has a fixing part 71 on one end facing the dynamic die casting mold 4. The dynamic die casting mold 4 has a groove 41 that matches each fixing part 71. Each fixing part 71 is inserted into the groove 41 at the corresponding position. Each fixing part 71 has a countersunk hole 72 perpendicular to the guide post 5.

Each positioning post 73 is inserted into the positioning hole 43 at the corresponding position, and the outer peripheral wall of each positioning post 73 fits against the inner peripheral wall of the corresponding positioning hole 43. With this structure, when the fixing part and the groove are engaged, the positioning post can be inserted into the positioning hole to position the fixing part and the groove. This facilitates the process of inserting the fixing part into the groove. After the positioning post and the positioning hole are engaged, the reliability and stability of the fixing part and the dynamic die casting mold are improved. In other words, the reliability and stability of the wedge block and the dynamic die casting mold are improved.

[0020] Each positioning post 73 has an annular chamfered surface 731 at its outer edge away from the fixing part 71. The annular chamfered surface 731 is used to cooperate with the hole wall of the positioning hole 43 for guidance so that the positioning post 73 can be inserted into the positioning hole 43 at the corresponding position. With this structure, under the action of the annular chamfered surface, when the positioning post is inserted into the positioning hole, the positioning post can cooperate with the hole wall of the positioning hole for guidance so that the positioning post can be inserted into the positioning hole, which can facilitate the insertion of the positioning post into the positioning hole.
