A new type of splitter mold

Abstract

The utility model provides a new type of diverter mold, which belongs to the field of mold technology. It solves the problem that the traditional diverter mold structure will cause flash to come out along the edge of the lower punch, and because the connecting pipe is tightly matched with the mold, graphite powder and air cannot be removed, resulting in the risk of rounded corners at the bottom of the product. The new type of diverter mold includes a mold body, which is composed of an outer sleeve, a lower mold body, and a lower punch for drilling a hole in the bottom of the lower mold body. A cavity is formed in the lower mold body, and a working cavity is arranged at the bottom of the cavity. The working cavity is a straight-through structure, and the lower punch cooperates with the working cavity. A guide part for preventing the lower punch from offsetting during operation is arranged at the bottom of the lower mold body, and a positioning member for positioning the lower punch is arranged on the guide part. The utility model has the advantages of high safety and long service life.

Description

Technical Field

[0001] The utility model belongs to the technical field of molds and relates to a diverter mold, in particular to a novel diverter 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] The traditional manifold mold structure will cause flash to come out along the edge of the lower punch, and because the pipe and the mold are tightly fitted, graphite powder and air cannot be removed, resulting in the risk of rounded corners at the bottom of the product. In addition, under this structure, the outer diameter of the lower punch will be relatively thin, and the impact resistance will be poor, and the punch will often break or bend. If the pipe and the mold are not tightly fitted or there is an inclination after being tightly fitted with the mold, flash will be discharged from multiple places, increasing the risk of punch bending or breaking. Summary of the invention

[0004] The purpose of the utility model is to provide a new high-performance manifold die for the above-mentioned problems existing in the prior art.

[0005] The purpose of the utility model can be achieved through the following technical solutions: a new type of diverter mold, characterized in that it includes a mold body, the mold body is composed of an outer sleeve, a lower mold body and a lower punch for drilling a hole in the bottom of the lower mold body, a cavity is formed in the lower mold body, and a working cavity is arranged at the bottom of the cavity, the working cavity is a straight-through structure, the lower punch cooperates with the working cavity, the bottom of the lower mold body is located in the working cavity and is provided with a guide part for preventing the lower punch from offsetting during operation, and a positioning member for positioning the lower punch is arranged on the guide part.

[0006] In the above-mentioned novel diverter mold, the positioning member includes a box body, a return spring and an elastic bracket, a circular protrusion is arranged on the elastic bracket, and the return spring is sleeved on the elastic bracket.

[0007] In the above-mentioned novel diverter head mold, a drill bit for drilling holes is arranged on the top of the lower punch, and a positioning groove matching with the circular protrusion is arranged on the lower punch.

[0008] Compared with the prior art, the new type of diverter mold, mold and mold accessories have shortened processing time, reduced mold processing time, eliminated the processing / assembly process of the connecting pipe, reduced processing time and cutting amount of the lower punch, and effectively solved the problem of graphite powder and air blocking in the mold, resulting in rounded corners of the product. The lower punch is more stable and not easy to tip over due to the lengthened mold guide, reducing the risk of flash being longer on one side and shorter on the other, and extending the life of the lower punch.

[0012] 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.

[0013] like Figure 1 , Figure 2 As shown, the new type of diverter mold includes a mold body 1, which is composed of an outer sleeve 2, a lower mold body 3 and a lower punch 4 for drilling a hole at the bottom of the lower mold body 3. The outer diameter of the lower punch 4 is increased, and the impact resistance is stronger than the original structure. A cavity 6 is formed in the lower mold body 3, and a working cavity 7 is arranged at the bottom of the cavity 6. The working cavity 7 is a straight-through structure, which adopts the straight-through structure of the lower punch 4 and the mold and lengthens the punch guide length to change the flash path position. The lower punch 4 cooperates with the working cavity 7. By adjusting the stroke of the lower punch 4, the height of the small circle of the product can be controlled. The bottom of the lower mold body 3 is located in the working cavity 7 and a guide portion 7 is arranged in the working cavity 7 for preventing the lower punch 4 from offset during operation. A positioning member 8 for positioning the lower punch 4 is arranged on the guide portion 7.

[0014] To further explain, the positioning member 8 includes a box body 9 , a return spring 10 and an elastic bracket 11 . The elastic bracket 11 is provided with a circular protrusion 12 , and the return spring 10 is sleeved on the elastic bracket 11 .

[0015] To elaborate further, a drill bit 13 for drilling is provided on the top of the lower punch 4, and a positioning groove 14 matching with the circular protrusion 12 is provided on the lower punch 4. The cooperation between the circular protrusion 12 and the positioning groove 14 prevents the lower punch 4 from deviating during the movement, and is used to fix the lower punch 4. When the lower punch 4 finishes drilling and is ready to come out, the circular protrusion 12 will be pressed into the box body 9. After the lower punch 4 has completely passed the positioning piece 8, the reset spring 10 and the circular protrusion 12 are reset.

[0016] 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.

[0017] Although the present invention uses the terms such as mold body 1, outer sleeve 2, lower mold body 3, lower punch 4, mold cavity 6, working cavity 7, guide part 7, positioning member 8, box body 9, return spring 10, elastic bracket 11, round protrusion 12, drill 13, positioning groove 14, 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 utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
