Description

Technical Field

[0001] The utility model relates to the technical field of iron frame shielding cover molds, in particular to a production mold suitable for small-size iron frame shielding covers. Background Art

[0002] An iron frame shielding cover, also known as an iron sheet shielding cover or an electromagnetic shielding cover, is an electromagnetic shielding device, usually made of a frame structure of iron (or an iron-containing alloy), used to prevent electromagnetic interference (EMI) or reduce electromagnetic signal leakage. The design of the production mold for the iron frame shielding cover is a very crucial link in the production process, which is directly related to the dimensional accuracy, production efficiency and cost control of the shielding cover. For large-volume production requirements, multi-cavity progressive dies are widely used because they can provide higher production efficiency and more economical unit product cost, and are suitable for the production of small-size iron ore shielding covers.

[0003] When using a mold to produce an iron frame shielding cover, it is necessary to prepare iron sheet or iron plate materials, select a sheet with appropriate thickness and material according to the design specifications of the shielding cover, clean the surface of the mold to ensure that there are no impurities and oil stains between the mold and the material during the production process, and use stamping technology to perform operations such as pressing, shearing, and bending on the iron plate in the mold to achieve the required shape and size. Mechanical processing such as riveting and welding is performed on the shielding cover to achieve the structural strength required in the shielding cover design.

[0004] However, some existing molds cannot collect the waste iron sheets generated by stamping in a timely manner during the production of shielding covers, resulting in the accumulation of waste iron sheets and the produced shielding covers together, which requires manual separation, very troublesome. Moreover, the template of the mold is welded to the fixed seat and cannot be replaced according to the specifications and shapes of the shielding frames to be produced, reducing the practicality of the mold. Therefore, a production mold suitable for small-size iron frame shielding covers is proposed to solve the above problems. Summary of the Utility Model

[0026] Referring to Figure 1 , Figure 2 and Figure 4 , an embodiment provided by the present utility model: A production mold suitable for small-sized iron frame shielding covers includes a first fixing plate 1 and an upper die assembly. Three first positioning holes 2 are equidistantly opened at the front and rear ends of the top of the first fixing plate 1. A first through groove 3 is opened in the middle of the first fixing plate 1. A scrap hopper 4 is fixedly connected inside the first through groove 3. The top of the first fixing plate 1 is fixedly connected with a lower die holder 5.

[0027] Three second positioning holes 6 are equidistantly opened at the front and rear ends of the top of the lower die holder 5 of the present utility model. A third positioning hole 7 is opened between two adjacent second positioning holes 6 at the top of the lower die holder 5. A second through groove 8 is opened in the middle of the lower die holder 5. A number of fourth positioning posts 19 are fixedly connected to the front and rear ends of the top of the lower die holder 5 at both ends of the second through groove 8.

[0028] First limiting grooves 9 are opened at both ends of the second through groove 8 of the present utility model. A lower template 15 is arranged inside the second through groove 8. A number of scrap holes 32 are arranged at the top of the lower template 15. First connecting blocks 16 are fixedly connected to both ends of the lower template 15. Card slots 17 are opened at the front and rear ends of the two first connecting blocks 16. The first connecting blocks 16 are respectively slidably connected with the first limiting grooves 9 on the same side. Slide grooves 10 are opened at the front and rear ends of the first limiting grooves 9. Clamping components are arranged at the front and left and right ends of the lower die holder 5. The two clamping components are respectively clamped and connected with the card slots 17 on the same side.

[0029] Through the cooperation between the upper die assembly and the waste hole 32 on the lower template 15, when producing the shielding case, the waste iron sheet can be synchronously brought into the waste hopper 4 through the waste hole 32. Since the left and right sides inside the waste hopper 4 are beveled, the waste iron sheet flows through the inside of the waste hopper 4 to the bottom outlet of the waste hopper 4, and then flows out of the fixed plate 1 from the bottom outlet of the waste hopper 4. Through the cooperation between the clamping component and the clamping groove 17 on the lower template 15, the lower template 15 can be replaced.

[0030] Referring to Figure 2 and Figure 3 , the clamping component of the present utility model includes a knob 11. The knobs 11 are rotatably connected to the front end of the lower die base 5.

[0031] Rotate the knob 11 to rotate the bidirectional screw 12. Since the bidirectional screw 12 is threadedly connected with the T-shaped block 13, when the bidirectional screw 12 rotates, it drives the two T-shaped blocks 13 and the two clamping blocks 14 to move towards the far ends of the sliding grooves 10 respectively, so that the clamping blocks 14 are disengaged from the clamping grooves 17 on the connecting block 16.

Bolts 27 are threadedly connected inside the six limiting grooves 26. The top ends of the bolts 27 penetrate through the top of the fixed plate 20. An upper template 28 is arranged inside the through groove 25.

[0035] At the bottom end of the upper template 28 of the present utility model, several waste columns 30 are fixedly connected. At the left and right ends of the upper template 28 and at the left and right ends of the front and back sides of the upper template 28, second connecting blocks 29 are fixedly connected. The six second connecting blocks 29 are respectively slidably connected to the second limiting grooves 26 on the same side. The top ends of the second connecting blocks 29 are respectively threadedly connected to the bottom ends of the bolts 27 on the same side.

[0036] At the bottom end of the first positioning column 21 of the present utility model, it is engaged with the corresponding first positioning hole 2, the second positioning column 23 is engaged with the corresponding second positioning hole 6, the third positioning column 24 is engaged with the corresponding third positioning hole 7, and the fourth positioning column 19 is engaged with the corresponding fourth positioning hole 31.

By sequentially rotating the bolts 27, the upper template 28 can be removed and replaced.
