Description

Technical Field

[0001] The utility model relates to the field of injection molds, in particular to an injection mold for a charger shell. Background Art

[0002] Moulds are various moulds and tools used in industrial production to obtain the required products by methods such as injection moulding, blow moulding, extrusion, die casting or forging, smelting, and stamping. In short, moulds are tools used to make moulded objects. This tool is composed of various parts, and different moulds are composed of different parts. It mainly realizes the processing of the shape of the object by changing the physical state of the moulded material. It is known as the "mother of industry". The charger shell injection mould can realize the injection moulding of the charger shell and can produce charger shells in batches.

[0003] Most of the existing charger shell injection molds have too simple structures. The fixed mold is usually fixed, which is inconvenient to remove and not conducive to overall maintenance. Most of them are cooled by opening through holes in the mold to allow cooling water to flow through and remove the heat from the mold. However, opening holes is more troublesome and the heat dissipation effect is not ideal. Utility Model Content

The inside of the fixed mold 41 is movably connected with a female mold 48, and the bottom of the movable mold 42 is movably connected with a male mold 49. The outer sides of the female mold 48 and the male mold 49 are fixedly connected with locking columns 410 that penetrate the fixed mold 41 and the movable mold 42 respectively. The outside of the locking column 410 is movably installed with a fixing nut 3 411.

[0023] By removing the fixing nut 1 45 on the rear side of the fixed mold 41 and the fixing nut 2 47 on the top of the support rod 2 respectively, the fixing screw 44 is pulled out from the front side of the clamping frame 43, and the fixed mold 41 is removed from the boss on the top of the base 1. The top plate 3 and the movable mold 42 are disassembled by moving the top plate 3 and the movable mold 42 upward along the support rod 2. By removing the fixing nut 3 411 on the outside of the fixed mold 41 and the movable mold 42, the concave mold 48 and the punch 49 are respectively separated from the inner sides of the fixed mold 41 and the movable mold 42 for disassembly, which is convenient for maintenance, inspection and replacement.

[0024] like Figure 4 and Figure 5As shown, a cooling water trough 412 is provided on the top of the fixed mold 41, a stepped groove 413 is provided on the upper inner side of the fixed mold 41, the die 48 is movably connected to the fixing nut 3 411 and the inner side of the stepped groove 413, and an outlet pipe 415 and an inlet pipe 416 connected to the cooling water trough 412 are fixedly installed on both sides of the bottom of the fixed mold 41, and the bottom of the cooling water trough 412 is fixedly connected to a support block 417 that fits the bottom of the die 48.

[0025] The external water pipe is connected through the water outlet pipe 415 and the water inlet pipe 416, and the cooling water is circulated by injecting and discharging cooling water into the cooling water tank 412. The cooling water wraps the entire outer side of the die 48, so that the cooling water takes away the heat of the die 48 through heat exchange, and the heat dissipation effect is improved by increasing the contact area with the die 48.

[0026] like Figure 2 As shown, a boss corresponding to the clamping frame 43 is provided on the top of the base 1, and a fixing screw 44 penetrates the interior of the boss.

[0027] The boss is provided to facilitate corresponding engagement with the card frame 43 , and the fixing screw 44 passes through the inside of the boss, thereby fixing and installing the fixed mold 41 and facilitating its disassembly.

[0028] like Figure 1 and Figure 2 As shown, the top plate 3 is movably connected to the top of the support rod 2, and the fixing nut 47 is located at a height above the top plate 3.

[0029] The top plate 3 is limited in position by the second fixing nut 47 which is located above the top plate 3 and connected to the support rod 2 .

[0030] like Figure 3 As shown, the four corners of the top of the fixed mold 41 are fixedly connected with positioning posts 418 , and the interior of the movable mold 42 is provided with through holes corresponding to the positioning posts 418 .

[0031] By setting the positioning posts 418 , when the movable mold 42 moves downward, the internal through holes thereof dock with the positioning posts 418 , thereby ensuring the alignment of the fixed mold 41 and the movable mold 42 .

[0032] like Figure 5 As shown, the height of the cooling water trough 412 is greater than the height of the die 48 .

[0033] The cooling water trough 412 is fixedly larger than the die 48 so that a cooling water channel is left between the cooling water trough 412 and the die 48. The cooling water in the cooling water trough 412 covers the outside of the die 48, thereby increasing the contact area and improving the cooling effect.

[0034] like Figure 4 As shown, a sealing strip 414 is movably engaged at the top of the stepped groove 413 .

[0035] The female die 48 is installed in the stepped groove 413 to press the sealing strip 414 so as to improve the sealing effect.

[0036] The following is a detailed description of the working principle of the charger shell injection mold.

[0037] like Figures 1 to 5 As shown, the hydraulic cylinder 5 drives the movable mold 42 to move downward, and the movable mold 42 drives the punch 49 to move downward so that the fixed mold 41 and the movable mold 42 are fitted together, and the punch 49 is extended into the inside of the die 48, and the material is added through the injection hole opened on the movable mold 42 for injection molding. The external water pipe is connected through the outlet pipe 415 and the inlet pipe 416, and the cooling water is circulated by injecting and discharging cooling water into the cooling water tank 412. The cooling water is wrapped around the entire outer side of the die 48, so that the heat of the die 48 is taken away by the cooling water through heat exchange, and the heat dissipation effect is improved by increasing the contact area with the die 48. When maintenance is needed, the cooling water is removed by the cooling water. By respectively removing the fixing nut 1 45 located on the rear side of the fixed mold 41 and the fixing nut 2 47 on the top of the support rod 2, the fixing screw 44 is pulled out from the front side of the clamping frame 43 after the fixing nut 1 45 is removed, so that the fixed mold 41 can be removed from the boss on the top of the base 1, and the top plate 3 is removed from the top of the support rod 2, and the movable mold 42 is removed by moving it upward along the support rod 2. Then, by removing the fixing nut 3 411 on the outside of the fixed mold 41 and the movable mold 42, the concave mold 48 and the punch 49 are respectively separated from the inner sides of the fixed mold 41 and the movable mold 42 for removal, which is convenient for maintenance, inspection and replacement.
