Technical Field

[0001] The utility model relates to the technical field of automobile casting molds, and particularly relates to an automobile casting mold which is convenient to disassemble, assemble and use in combination. Background Technique

[0002] Automobile casting molds come in various sizes. After the casting of a smaller casting mold is completed and the mold is disassembled, even if the connecting parts are removed, the mold may still not be separable and external force may be needed to pull the mold. When pulling the mold, a hammer may also be needed to strike the mold. In this case, corresponding pulling connecting parts are required for the mold, and the setting of the connecting parts should not affect the striking of the mold. Content of the Utility Model

[0003] The purpose of the utility model is to provide an automobile casting mold which is convenient to disassemble, assemble and use in combination, so as to solve the problem mentioned in the above background technique that the mold needs pulling connecting parts and the setting of the connecting parts should not affect the striking of the mold.

[0004] To achieve the above purpose, the utility model provides the following technical solution:

[0005] An automobile casting mold which is convenient to disassemble, assemble and use in combination, includes a mold, and a connecting part is fixedly installed on the outer side of the mold. The connecting part includes an inner fixing part, an outer sleeve part and a threaded head. The outer sleeve part is sleeved and installed on the outer side of the inner fixing part. Both the inner fixing part and the outer sleeve part are structures that increase obliquely. The large end of the outer sleeve part is integrally connected with the threaded head.

[0006] As a further description of the above technical solution:

[0007] The length of the outer sleeve part is less than the length of the inner fixing part.

[0008] As a further description of the above technical solution:

[0009] The diameter of the small end of the outer sleeve part is less than the diameter of the large end of the inner fixing part.

[0010] As a further description of the above technical solution:

[0011] There is a gap between the large end of the outer sleeve part and the large end of the inner fixing part.

[0012] As a further description of the above technical solution:

[0013] The gap is between 5 mm and 20 mm.

[0014] As a further description of the above technical solution:

[0015] The thread of the threaded head is provided on the inner wall.

[0016] Compared with the prior art, the utility model provides an automobile casting mold which is convenient for disassembly, assembly and combined use, and has the following beneficial effects:

[0017] 1. In the utility model, by arranging a connecting piece on the outer side of the mold, the structure of the connecting piece is extremely simple. The outer sleeve of the connecting piece can rotate and be threadedly fixed with the connecting head of the pulling machine, and the mold is separated by means of a puller;

[0018] 2. In the utility model, the structure of the connecting piece is special, so that the inner fixing piece and the outer sleeve have a self-locking function. The outer sleeve can rotate and move back and forth. While pulling, it can also meet the knocking requirement of the mold. The knocking action will not affect the outer sleeve, and neither the inner fixing piece nor the outer sleeve will be damaged. When the puller moves forward, it can push the inner fixing piece, which is convenient for the alignment and assembly of the mold. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0025] Embodiment:

[0026] Please refer to Figures 1 - 3 , the utility model provides an automobile casting mold which is convenient for disassembly, assembly and combined use, including a mold 1. A connecting piece 2 is fixedly installed on the outer side of the mold 1. The connecting piece 2 includes an inner fixing piece 201, an outer sleeve 202 and a threaded head 203. The outer sleeve 202 is sleeved and installed on the outer side of the inner fixing piece 201. Both the inner fixing piece 201 and the outer sleeve 202 are structures that increase obliquely. The large end of the outer sleeve 202 is integrally connected with the threaded head 203.

[0027] Specifically, the length of the outer sleeve 202 is less than that of the internal fixing member 201, the diameter of the small end of the outer sleeve 202 is less than the diameter of the large end of the internal fixing member 201, and there is a spacing between the large end of the outer sleeve 202 and the large end of the internal fixing member 201, with the spacing being between 5 mm and 20 mm. The internal fixing member 201 and the outer sleeve 202 are anti-disengagement, and the outer sleeve 202 can move back and forth on the internal fixing member 201.

[0028] Specifically, as Figure 3 shown, the thread of the threaded head 203 is provided on the inner wall, facilitating threaded fixation with the connecting head of the pulling machine. Moreover, when the connecting head of the pulling machine moves forward, it can push the internal fixing member 201.

[0029] Working principle:

[0030] When in use, rotate the outer sleeve 202 to thread-fix the threaded head 203 with the connecting head of the pulling machine. The pulling machine can be a cylinder or the like. For example, a stud can be welded to the end of the cylinder. When the connecting head of the pulling machine is pushed forward, it can also push the mold 1 to assist in its alignment and assembly;

[0031] The puller pulls the threaded head 203 to separate the mold 1. Since the outer sleeve 202 is sleeved on the internal fixing member 201 and the outer sleeve 202 can move forward and loosen on the internal fixing member 201, gently moving the puller forward can strike the mold 1.

[0032] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
