The new valve body mold includes a mold body, which is composed of a lower mold body and a transverse punch for drilling holes into the lower mold body. A cavity for casting the valve body is formed in the lower mold body, and a punching cavity for punching holes in the valve body is connected to one side of the cavity. The transverse punch cooperates with the punching cavity, and a first step groove and a second step groove are provided in the punching cavity. An anti-impact portion is formed between the first step groove and the second step groove, and a curved step for preventing impact is provided on the anti-impact portion. The utility model has the advantage of reducing production costs.

Description

Technical Field

[0001] The utility model belongs to the technical field of molds and relates to a valve body mold, in particular to a novel valve body mold. Background Art

[0002] Molds are various molds and tools used in industrial production to obtain the desired products by injection molding, blow molding, extrusion, die casting or forging, smelting, stamping and other methods. 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.

[0003] Under the long-term punching of the punch, the traditional valve body mold will collide with each other, which can easily cause damage to the inside of the valve body mold and reduce the precision of the product. In addition, the punch is slender and easy to be damaged during the collision, and its life is short, which not only increases the production cost but also affects the production efficiency. Summary of the invention

[0004] The purpose of the utility model is to provide a novel high-efficiency and low-cost valve body mold in view of the above problems existing in the prior art.

[0005] The purpose of the utility model can be achieved through the following technical solutions: a new valve body mold, including a mold main body, the mold main body is composed of a lower mold body and a transverse punch for drilling holes into the lower mold body, and is characterized in that a cavity for casting the valve body is formed in the lower mold body, and a stamping cavity for punching holes in the valve body is connected to one side of the cavity, the transverse punch cooperates with the stamping cavity, a first step groove and a second step groove are arranged in the stamping cavity, an anti-impact portion is formed between the first step groove and the second step groove, and the anti-impact portion is provided with a curved step for preventing impact.

[0006] In the above-mentioned novel valve body mold, the horizontal punch is provided with a first step and a second step which match with the first step groove and the second step groove, and a punching head is provided at the top of the horizontal punch.

[0007] Compared with the prior art, the new valve body mold has changed the mold and the punch. Because the punch is slender and has a short life, the punch can be stepped to greatly extend its life, ensure the gap between the punch and the mold, and reduce production costs.

[0011] 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.

[0012] like Figure 1 , Figure 2 As shown, the new valve body mold includes a mold body 1, which is composed of a lower mold body 2 and a horizontal punch 3 for drilling holes into the lower mold body 2. A cavity 4 for casting the valve body is formed in the lower mold body 2, and a punching cavity 5 for punching holes in the valve body is connected to one side of the cavity 4. The horizontal punch 3 cooperates with the punching cavity 5 to process the valve body through mutual cooperation. A first step groove 6 and a second step groove 7 are provided in the punching cavity 5, and an anti-impact portion 8 is formed between the first step groove 6 and the second step groove 7. The anti-impact portion 8 can reduce the impact force between the punch and the mold, reduce the damage to the internal assembly of the mold caused by the impact force, and a curved step 9 for preventing impact is provided on the anti-impact portion 8.

[0013] To further elaborate, the transverse punch 3 is provided with a first step 10 and a second step 11 which cooperate with the first step groove 6 and the second step groove 7. The mutual cooperation between the steps and the step grooves prevents the transverse punch 3 from being easily damaged during the punching process, and a punch head 12 is provided at the top of the transverse punch 3, and the punch head 12 punches holes in the valve body that has been plasticized.

[0014] 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.

[0015] Although the present invention uses the terms such as die body 1, lower die body 2, horizontal punch 3, die cavity 4, punching cavity 5, first step groove 6, second step groove 7, impact protection part 8, curved step 9, first step 10, second step 11, punching head 12, 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.
