Description

Technical Field

[0001] The utility model belongs to the field of molds, and particularly relates to a novel gear mold. Background Art

[0002] When a gear mold is used to process gear parts, the mold may wear out due to long-term use, causing deviations in the processed gears. Traditional gear molds require the entire mold to be removed and replaced, which is time-consuming and laborious, and will cause waste in undamaged areas of the mold. Summary of the invention

[0003] The purpose of the utility model is to provide a new gear mold in view of the above problems existing in the prior art.

[0004] The purpose of the utility model can be achieved through the following technical solutions: A new gear mold, including a mold body, characterized in that the mold body is composed of a plurality of mold blocks that can be spliced ​​with each other, one side of the mold block is provided with a protrusion for splicing, and the other side of the mold block is provided with a groove for matching the protrusion;

[0005] The lower end of the mold block is provided with a blocking plate for splicing and preventing the medium in the mold body from flowing out, and the lower end of the mold block is provided with a splicing groove that is the same as the splicing blocking plate;

[0006] A notch is provided at the lower end of the protrusion, a convex block which can move axially is arranged in the notch, a rotating shaft is arranged at the connection between the protrusion and the notch, the rotating shaft can drive the protrusion to move into the notch, and elastic elements which can be elastically reset are arranged at the upper and lower ends between the protrusion and the notch.

[0007] In the above-mentioned novel gear mold, the lower end of the protrusion is in an arc shape, which is used to reduce the damage to the groove when the protrusion slides in the groove.

[0008] In the above-mentioned novel gear mold, the edges of the protrusions are all arc-shaped.

[0009] In the above-mentioned novel gear mold, the blocking plates are connected to each other to form a circular ring.

[0010] Compared with the prior art, the novel gear mold is composed of a plurality of split mold blocks. When a mold block is damaged, only the corresponding mold block needs to be replaced, which greatly reduces waste. Installation and disassembly only require plugging and unplugging, which reduces time costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0016] like Figure 1 , Figure 2 , Figure 3 As shown, the novel gear mold comprises a mold body, which is composed of a plurality of mold blocks 1 that can be spliced ​​with each other. A protrusion 2 for splicing is provided on one side of the mold block 1, and a groove 3 for matching the protrusion 2 is provided on the other side of the mold block 1;

[0017] The lower end of the mold block 1 is provided with a blocking plate 4 for splicing and preventing the medium in the mold body from flowing out, and the lower end of the mold block 1 is provided with a splicing groove 5 which is the same as the splicing blocking plate 4;

[0018] A slot 6 is provided at the lower end of the protrusion 2, and an axially movable protrusion 7 is provided in the slot 6. A rotating shaft 8 is provided at the connection between the protrusion 7 and the slot 6, and the rotating shaft 8 can drive the protrusion 7 to move into the slot 6. Elastic elements 9 that can be elastically reset are provided at the upper and lower ends between the protrusion 7 and the slot 6.

[0019] To be more specific, the lower end of the protrusion 7 is arc-shaped, which is used to reduce the damage to the groove 3 when the protrusion 2 slides in the groove 3.

[0020] To be more specific, the edges of the protrusions 2 are all arc-shaped.

[0021] To be more specific, the blocking plates 4 are connected to each other to form a ring shape, so that the medium introduced into the mold body is retained outside.

[0022] During installation, align the protrusion 2 with the groove 3 and slide downward. Since the lower end of the protrusion 7 is in an arc shape, during the downward sliding process, a jam will occur in the groove 3, which will push the protrusion 7 into the groove 6, thereby reducing the friction between the protrusion 2 and the groove 3. After pushing the protrusion 2 to the bottom end of the groove 3, the elastic element 9 in the groove 6 will reset the protrusion 7, and the installation is completed.

[0023] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0024] Although the present invention uses the terms such as mold block 1, protrusion 2, channel 3, blocking plate 4, joint groove 5, notch 6, convex block 7, rotating shaft 8, elastic element 9, etc. more frequently, it does not exclude the possibility of using other terms. The use of these terms is only for the purpose of more conveniently describing and explaining the essence of the present invention; interpreting them as any additional limitation is contrary to the spirit of the present invention.
