Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to an integrated muffler mold that reduces impacts. Background Technology

[0002] Muffler molds are specialized tools used to manufacture mufflers. They use stamping equipment to apply pressure to the metal sheet inside the mold with specific shapes and structures, causing it to separate or plastically deform within the mold, thereby obtaining muffler parts of the required shape. They are characterized by high production efficiency, low cost, and suitability for mass production.

[0003] In the existing technology, when the mold is used to stamp the muffler, there are some relatively thin edge structures on the edge of the mold. Different sizes of molds are used on the stamping machine, and the replaced molds are temporarily placed aside. However, the production workshop environment is complex and there are many kinds of metal instruments. If a metal instrument accidentally falls on these molds, it is very likely to cause damage such as bumps to the edge of the mold, which will affect the accuracy and service life of the mold and increase the production cost. Utility Model Content

[0004] This utility model relates to an integrated muffler mold that reduces impacts, addressing the problem that replaced molds are temporarily placed aside. However, the production workshop environment is complex, with many different kinds of metal instruments. If a metal instrument accidentally falls onto these molds, it is very likely to cause damage such as impacts to the edges of the molds, thereby affecting the accuracy and service life of the molds and increasing production costs.

[0005] This utility model provides an integrated muffler mold that reduces impact damage, specifically comprising: an integrated mold body, the integrated mold body having a circular structure, and a mold hole being formed at the center of the top of the integrated mold body, and a mold mounting groove being formed at the bottom of the integrated mold body; a guide groove being formed at a relative position on the outer side of the integrated mold body; a spring being installed at the bottom inner side of the guide groove, and a guide slide being installed at the bottom inner side of the guide groove via the spring; a protective cover being installed on the outer side of the guide slide; the protective cover having a ring structure, and the protective cover being slidably installed on the outer side of the integrated mold body.

[0006] Furthermore, a storage groove and a positioning groove are respectively provided on the top side of the integrated mold body; a connecting groove is also provided on the top of the integrated mold body; the two ends of the connecting groove are respectively connected to the top of the storage groove and the positioning groove.

[0007] Furthermore, the positioning groove is a cylindrical structure, and a spring is installed on the inner bottom of the positioning groove, and a positioning rod is slidably installed on the inner bottom of the positioning groove through the spring.

[0008] Furthermore, a rotating rod is installed on the top of the positioning rod; the rotating rod has a cylindrical structure, and a connecting plate is installed on one side of the top of the rotating rod.

[0009] Furthermore, a sealing element is rotatably installed on the side end of the connecting plate; the sealing element is slidably installed inside the storage tank, and the sealing element is also slidably installed inside the mold hole.

[0010] Furthermore, a guide rod is installed on the bottom outer side of the protective cover.

[0011] Furthermore, the guide rod is a cylindrical structure, and a limiting protrusion is installed at the outer end of the guide rod, and a guide plate is slidably installed on the guide rod; a force-bearing support plate is installed at the bottom of the guide plate, wherein the force-bearing support plate is an arc-shaped plate structure.

[0012] This utility model provides an integrated muffler mold that reduces impact damage, and has the following beneficial effects:

[0013] When in use, the mold is idle. Whether placed on the ground or in other storage equipment, the force-bearing support plate will move the protective cover upward above the top of the integrated mold body when it encounters an obstacle via the guide rod and guide plate. This provides comprehensive and effective protection for the mold hole. In complex workshop environments, the protective cover can effectively block falling metal machinery and other foreign objects, preventing damage to the mold hole from impacts, scratches, etc., thus ensuring the integrity of the mold hole. This provides precise forming conditions for subsequent muffler processing, fundamentally improving the processing quality of the muffler, reducing the defect rate caused by mold damage, and lowering production costs.

[0014] Furthermore, the smooth, seamless design of the inner surface of the die provides an ideal forming environment for the processing of aluminum mufflers. During the stamping process, the die holes can be filled evenly, and defects such as flash due to gaps will not occur. This ensures the smoothness and precision of the muffler surface, which not only enhances the aesthetic appearance of the product, but also strengthens the sealing and noise reduction performance of the muffler, thereby improving the product's usability and reliability.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] Please refer to Figures 1 to 6 :

[0030] Example 1: This utility model proposes an integrated muffler mold that reduces impacts, including: an integrated mold body 1, which is circular in structure, and has a mold hole 101 at the middle of the top of the integrated mold body 1, and a mold mounting groove 102 at the bottom of the integrated mold body 1.

[0031] In this embodiment, when the muffler mold is in use, the inner surface of the mold hole 101 at the top of the integrated mold body 1 is relatively smooth and has no gaps. Therefore, when some aluminum mufflers are processed, no flash will be generated on the surface after processing, ensuring the smoothness of the muffler surface and improving the product quality of the muffler. The integrated mold structure of the integrated mold body 1 reduces the complexity of mold assembly and ensures product quality. The mold mounting groove 102 at the bottom of the integrated mold body 1 facilitates installation on the base of the stamping equipment and facilitates precise installation and positioning of the integrated mold body 1.

[0032] In Example 2, based on Example 1, a storage groove 2 and a positioning groove 201 are respectively provided on one side of the top of the integrated mold body 1; a connecting groove 202 is also provided on the top of the integrated mold body 1; the two ends of the connecting groove 202 are respectively connected to the top of the storage groove 2 and the top of the positioning groove 201; the positioning groove 201 is a cylindrical structure, and a spring is installed on the bottom inner side of the positioning groove 201, and a positioning rod 203 is slidably installed on the bottom inner side of the positioning groove 201 through the spring; a rotating rod 204 is installed on the top of the positioning rod 203; the rotating rod 204 is a cylindrical structure, and a connecting plate 205 is installed on one side of the top of the rotating rod 204; a sealing element 206 is rotatably installed on the side end of the connecting plate 205; the sealing element 206 is slidably installed inside the storage groove 2, and the sealing element 206 is also slidably installed inside the mold hole 101. When the muffler mold is in use, the sealing element 206 is stored inside the storage groove 2, and the connecting plate 205 is installed in the connecting groove 2. The interior of 02 ensures a relatively flat top surface for the integrated mold body 1, guaranteeing normal mold operation. When the integrated mold body 1 is idle, pulling the side end of the connecting plate 205 moves the sealing element 206 upward from the storage tank 2. The connecting plate 205 also moves the rotating rod 204 and the positioning rod 203 upward inside the positioning groove 201. The connecting plate 205 rotates the rotating rod 204 at the top of the positioning rod 203. The connecting plate 205 moves the sealing element 206 at the side end to be installed inside the mold hole 101. Under the action of the spring, the positioning rod 203 moves the rotating rod 204 and the connecting plate 205 downward. The sealing element 206 seals the mold hole 101. Since calendering oil is applied inside the mold hole 101 after mold use, the sealing element 206 seals the mold hole 101, reducing dust falling onto the calendering oil inside the mold hole 101, reducing the amount of cleaning work later, and reducing the problem of poor muffler processing quality caused by impurities.

[0033] In Example 3, based on Example 1, a guide groove 3 is provided at a relative position on the outer side of the integrated mold body 1; a spring is installed at the bottom inner side of the guide groove 3, and a guide slide plate 301 is installed at the bottom inner side of the guide groove 3 via the spring; a protective cover 302 is installed on the outer side of the guide slide plate 301; the protective cover 302 has a ring structure and is slidably installed on the outer side of the integrated mold body 1; a guide rod 303 is installed at the bottom outer side of the protective cover 302; the guide rod 303 has a cylindrical structure, and a limiting protrusion is installed at the outer end of the guide rod 303, and a guide plate 304 is slidably installed on the guide rod 303; a force-bearing support plate 305 is installed at the bottom of the guide plate 304, wherein the force-bearing support plate 305 has an arc-shaped plate structure. When the muffler mold is in use, the integrated mold body 1 is installed on the stamping equipment, and there are no other obstructions around the bottom of the integrated mold body 1. The guide plate 304 slides on the outer side of the guide rod 303, so that the force-bearing support plate 305 is slidably installed on the guide rod 303. The support plate 305 is away from obstructions. Under the action of the spring, it pulls the guide slide plate 301 to move downward along the guide groove 3. The outer end of the guide slide plate 301 drives the protective cover 302 to move downward on the outside of the integrated mold body 1, so that the top of the protective cover 302 is lower than the top of the integrated mold body 1, which facilitates the stamping process of the muffler. When the integrated mold body 1 is idle, it is moved to the ground or other storage equipment. When the force support plate 305 is obstructed, it drives the protective cover 302 to move upward through the guide plate 304 and the guide rod 303. The protective cover 302 drives the inner guide slide plate 301 to move upward inside the guide groove 3, so that the top of the protective cover 302 is higher than the top of the integrated mold body 1, which facilitates the protection of the mold hole 101. The protective cover 302 blocks falling metal machinery, ensures the integrity of the mold hole 101 on the integrated mold body 1, and improves the processing quality of the muffler.

[0034] The working principle of this embodiment: The inner surface of the mold hole 101 at the top of the integrated mold body 1 is relatively smooth without any gaps, ensuring the smoothness of the muffler surface processing. The storage tank 2 stores the sealing element 206. The connecting plate 205 is installed in the connecting groove 202, making the top surface of the integrated mold body 1 relatively flat. The integrated mold body 1 is installed on the stamping equipment. There are no other obstructions around the bottom of the integrated mold body 1. Under the action of the spring, the guide slide plate 301 is pulled to move downward along the guide slide groove 3. The guide slide plate 301 causes the top of the protective cover 302 to be lower than the top of the integrated mold body 1, which facilitates the stamping processing of the muffler. When the integrated mold body 1 is idle... The integrated mold body 1 is placed on the ground or in other storage equipment. When the force support plate 305 encounters an obstacle, it drives the protective cover 302 to move upward through the guide plate 304 and guide rod 303. The top of the protective cover 302 is higher than the top of the integrated mold body 1, which blocks falling metal machinery and ensures the integrity of the mold hole 101 on the integrated mold body 1. Then, the side end of the connecting plate 205 is pulled to move the sealing element 206 from the storage tank 2 into the mold hole 101. Under the action of the spring, the positioning rod 203 drives the rotating rod 204 and the connecting plate 205 to move downward. The sealing element 206 seals the mold hole 101, reducing dust falling on the calendering oil inside the mold hole 101 and reducing the amount of cleaning work in the later stage.
