Description

Technical Field

[0001] This utility model relates to the field of molds, and in particular to a mold that improves punching efficiency and positioning accuracy. Background Technology

[0002] In the mold industry, molds are various molds and tools used to obtain desired products through injection molding, blow molding, extrusion, die casting or forging, smelting, stamping and other methods. In short, a mold is a tool used to make shaped objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly achieves the processing of the shape of the object by changing the physical state of the material being molded.

[0003] The existing mold positioning pin is designed with a cylindrical appearance and a tapered inverted R design at the head. The height of the positioning pin is controlled by manually tapping it downwards, which makes the height impossible to fix. During the production process, it may loosen and sink. When it sinks to the tapered area at the head, it loses its positioning effect. In addition, when manually fitting the positioning pin, each positioning hole of the product needs to be fitted to the base of the positioning pin. This action is too inefficient, and there is a risk of product deviation during punching if the operator does not perform this action.

[0004] Therefore, it is necessary to provide a mold that improves punching efficiency and positioning accuracy to solve the above-mentioned technical problems. Utility Model Content

[0005] This utility model provides a mold that improves punching efficiency and positioning accuracy, solving the problem that the height of the positioning pin cannot be fixed and that when manually fitting the positioning pin, each positioning hole of the product needs to be fitted to the root of the positioning pin.

[0006] To solve the above-mentioned technical problems, this utility model provides a mold for improving punching efficiency and positioning accuracy, comprising:

[0007] A male top plate, wherein a pressure plate is provided at the bottom of the male top plate, a needle plate is provided at the bottom of the pressure plate, a panel is provided at the bottom of the needle plate, and a plurality of guide posts are provided at the bottom of the pressure plate, wherein the guide posts pass through the needle plate and the panel in sequence.

[0008] The female mold is located at the bottom of the panel. The female mold has a sliding hole inside, a base plate at the bottom, and a positioning pin inside.

[0009] A support sleeve is disposed on one side of the pressure plate. A sleeve is slidably connected inside the support sleeve, and a return spring is disposed at one end of the sleeve and inside the support sleeve.

[0010] Preferably, the positioning pin is umbrella-shaped, the diameter of the part of the positioning pin entering the mold is 1.5 mm, and the effective diameter of the root of the protruding part is 1.97 mm.

[0011] Preferably, the sleeve has an inner diameter of 2.5 mm and an outer diameter of 4.0 mm.

[0012] Preferably, a nut is fixedly connected to the bottom of the pressure plate, and the support sleeve is disposed inside the nut.

[0013] Preferably, a limiting hole is formed inside the master mold, and a limiting block is provided inside the limiting hole.

[0014] Preferably, the limiting hole has an internal thread, and the limiting block has an external thread that matches the internal thread.

[0015] Preferably, the limiting block has multiple rotating holes inside.

[0016] Compared with related technologies, this utility model has the following advantages: by designing the positioning pin in an umbrella shape, the height of the positioning pin can be fixed and will not sink. At the same time, by using a support sleeve in conjunction with a return spring, the sleeve can move and adjust its position along the inclined surface of the positioning pin after contacting the surface of the positioning pin, thereby ensuring the positioning accuracy of the product during punching.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] First embodiment:

[0025] Please refer to the following: Figure 1-3 The first embodiment of this invention provides a die for improving punching efficiency and positioning accuracy, comprising:

[0026] Male top plate 1, male top plate 1 is provided with pressure plate 2 at the bottom, pressure plate 2 is provided with needle plate 3 at the bottom, needle plate 3 is provided with panel 5 at the bottom, pressure plate 2 is provided with multiple guide posts 4 at the bottom, and the guide posts 4 pass through needle plate 3 and panel 5 in sequence.

[0027] The female mold 6 is located at the bottom of the panel 5. The female mold 6 has a sliding hole 7 inside, a base plate 8 at the bottom, and a positioning pin 9 inside.

[0028] Support sleeve 11 is located on one side of pressure plate 2. A sleeve 12 is slidably connected inside the support sleeve 11. A return spring 13 is provided at one end of the sleeve 12 and inside the support sleeve 11.

[0029] The support sleeve 11 has a movable hole inside, and a sliding block is slidably connected inside the movable hole. The bottom of the sliding block is fixedly connected to one end of the sleeve 12, and a return spring 13 is provided at the top of the sliding block and inside the support sleeve 11 to prevent the sleeve 12 from separating from the support sleeve 11.

[0030] The positioning pin 9 is umbrella-shaped. The diameter of the part of the positioning pin 9 that enters the mold is 1.5mm, and the effective diameter of the root of the protruding part is 1.97mm.

[0031] The inner diameter of sleeve 12 is 2.5 mm and the outer diameter is 4.0 mm.

[0032] The sleeve 12 is designed with an inner diameter of 2.5mm, an outer diameter of 4.0mm, and an outer diameter of 4.3mm at the root to form a hanging platform with a total length of about 28mm, ensuring that it protrudes 2-3mm from the stripper plate. During the die pressing process, the sleeve 12 presses down on the product to ensure punching accuracy.

[0033] A nut 10 is fixedly connected to the bottom of the pressure plate 2, and a support sleeve 11 is set inside the nut 10.

[0034] The surface of one end of the support sleeve 11 is threaded to match the nut 10. When one end of the support sleeve 11 is rotated to one side inside the nut 10, it can be moved to one side and separated, so that the support sleeve 11 can be removed. When installing the support sleeve 11, one end of the support sleeve 11 is rotated to one side behind the nut, so that it can be moved to a suitable position inside the support sleeve 11.

[0035] The working principle of this first embodiment is as follows:

[0036] When in use, by designing the positioning pin 9 in an umbrella shape, the height of the positioning pin 9 will not sink after it is installed into the mounting hole inside the female mold 6.

[0037] At the same time, when the top plate 1 moves downward, it drives the support sleeve 11 to move downward, so that the sleeve 12 contacts the surface of the positioning pin 9. While the sleeve 12 moves along the inclined surface of the positioning pin 9 to adjust its position, it moves upward inside the support sleeve 11 and squeezes the return spring 13, thereby ensuring the positioning accuracy of the product during punching.

[0038] In this first embodiment, the positioning pin 9 is designed in an umbrella shape, which can fix the height of the positioning pin 9 and prevent it from sinking. At the same time, the support sleeve 11 and the return spring 12 work together to allow the sleeve 12 to move and adjust its position along the inclined surface of the positioning pin 9 after it comes into contact with the surface of the positioning pin 9, thereby ensuring the positioning accuracy of the product during punching.

[0039] Second embodiment:

[0040] Please refer to the following: Figure 4 and Figure 5 Based on the first embodiment of this application, which provides a die for improving punching efficiency and positioning accuracy, the second embodiment of this application proposes another die for improving punching efficiency and positioning accuracy. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0041] Specifically, the difference in the mold for improving punching efficiency and positioning accuracy provided in the second embodiment of this application is that the mold for improving punching efficiency and positioning accuracy has a limiting hole 14 inside the mother mold 6, and a limiting block 15 is provided inside the limiting hole 14.

[0042] The limiting hole 14 has an internal thread, while the limiting block 15 has an external thread that matches the internal thread.

[0043] The limiting block 15 is rotatably connected to the surface of the positioning pin 9 and is used to cooperate with the limiting hole 14 to install and remove the positioning pin 9 while positioning the positioning pin 9. This makes it convenient to replace the positioning pin 9 after it wears down due to long-term friction between the positioning pin 9 and the sleeve 12.

[0044] The limiting block 15 has multiple rotating holes 16 inside.

[0045] The rotating hole 16 is used to facilitate the rotation of the limiting block 15 after a finger or tool is inserted into the rotating hole 16.

[0046] The working principle of this second embodiment is as follows:

[0047] In use, the positioning pin 9 can be removed by rotating the limiting block 15 to one side and moving it upward inside the limiting hole 14.

[0048] When installing the new positioning pin 9, after aligning the limiting block 15 with the limiting hole 14, rotate the limiting block 15 to one side, thereby moving it downwards to the appropriate position inside the limiting hole 14.

[0049] In this second embodiment, the positioning pin 9 is installed and removed by means of the limiting block 15 in conjunction with the limiting hole 14 and the rotating hole 16, thereby facilitating the replacement of the positioning pin 9.

[0050] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
