Description

Technical Field

[0001] This utility model relates to the field of industrial production auxiliary equipment technology, specifically a plastic shell injection mold. Background Technology

[0002] Injection molding is a method of shaping industrial products. Products are usually made using rubber injection molding and plastic injection molding. Injection molding can also be divided into injection molding compression molding and die casting. Compression molding is a processing technology that combines metal and plastic materials to create products. The specific steps include adding plastic particles that encapsulate metal parts into a mold, then heating and applying high pressure to bond the plastic and metal materials together. The final product has both the flexibility of plastic and the strength and durability of metal.

[0003] According to a search of existing Chinese patent number 202222223568.2, for compression molding equipment, the templates and molds are often installed in a fixed manner during the compression molding process. This means that under certain conditions, the same mold can only support the same specification of embossing on the workpiece material inside the mold cavity. Consequently, manufacturers need to prepare multiple different devices for backup when producing workpieces with different patterns, which increases production costs and adds to the economic burden.

[0021] like Figure 1-4 As shown in this embodiment: a plastic shell injection mold includes a mold 1. A mold groove 2 is provided in the middle of the surface of the mold 1. A mating hole 3 is provided on the upper edge of the mold 1 and outside the mold groove 2. There are several mold grooves 2 and several mating holes 3. The mold groove 2 is used to hold the raw material for embossing the workpiece. An installation rod 4 is inserted into the inside of the mating hole 3. A base 5 is fixedly connected to the top of the installation rod 4. A base plate 6 is fixedly connected to the inside of the base 5. The base plate 6 accommodates the screw 10 and fixes the mold base 7. The mold base 7 is fixedly connected to the lower surface of the base plate 6. The base 5, base plate 6 and mold base 7 are detachably fixedly connected by several sets of screws. Several templates are detachably connected to the lower surface of the mold base 7. The number of templates is the same as the number of mold grooves 2. At the same time, the mold base 7 and the mold groove 2 are vertically distributed. The mold groove 2 and the templates are matched to perform the embossing work.

[0022] Furthermore, a cylinder output shaft 8 is fixedly connected to the upper surface of the base plate 6, and the surface of the cylinder output shaft 8 passes through the interior of the upper surface of the base 5, which can effectively ensure the stability of the center of gravity of the entire device and meet the requirements of long-term use of the device.

[0023] Furthermore, several screws 10 are inserted into the surface of the base plate 6, and the number of screws 10 is the same as the number of mold slots 2. At the same time, a screw shaft 9 is rotatably connected inside the top of each screw 10, which more efficiently enhances the matching and coordination of various components during the operation of the overall device and effectively reduces the probability of various unexpected situations that may occur during use.

[0024] Furthermore, the end of the screw 10 is fixedly connected to the base plate 11 via a bearing, and an arc clamp 12 is fixedly connected to the left and right sides of the lower surface of the base plate 11 respectively. By matching the various components of the overall device during use, the coordination of the overall device is enhanced.

[0025] Furthermore, a central shaft 13 is fixedly connected to the inner middle position of the screw 10, and a clamping piece 14 is snapped onto the surface of the central shaft 13, which further enhances the fit strength of the overall device during use and avoids the situation of asymmetrical component matching during the use of the overall device.

[0026] Furthermore, the clip 14 has an "eight" shape in appearance, and a locking block 15 is fixedly connected to the lower left and right ends of the clip 14. According to the existing structure, they jointly support the overall device, enhance the coordination performance of the overall device during use, and enhance the durability of the overall device during use.

[0027] Furthermore, slots for accommodating the locking blocks 15 are provided on the lower left and right sides of the screw 10 surface, and the locking blocks 15 on both sides are symmetrically distributed on a horizontal line. By enhancing the flexible control capability of the overall device, the probability of the overall device malfunctioning during use is reduced.

[0028] The usage method of this embodiment is as follows: When using it, please refer to... Figure 1-4 First, the staff needs to manually align the template with the lower surface of the mold base 7 for installation. During the installation process, the staff manually inserts the upper surface of the template into the lower end of the screw 10. Then, the staff manually rotates the screw shaft 9 at the top of the screw 10. The rotation of the screw shaft 9 inside the screw 10 controls the displacement of the base plate 11 inside the screw 10. Since the arc clamps 12 distributed on the left and right sides of the end of the base plate 11 are fixedly connected to the lower surface of the base plate 11, they are driven by the base plate 11 and move synchronously inside the screw 10, thereby squeezing or releasing the clamping piece 14. This controls the extension or retraction of the locking block 15 on the lower surface of the screw 10. After the template is fixed, the base 5 is pressed down by the drive of the cylinder output shaft 8, so that the mold base 7 and the mold groove 2 are connected, completing the embossing work on the workpiece raw material.

[0029] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
