Description

Technical Field

[0001] This utility model specifically relates to a spring block positioning structure for preventing sticking of glued iron products. Background Technology

[0002] Glue-iron products are composite materials of glue and iron. In the process of glute-iron injection molding, the molten glue used for injection needs to enter the mold cavity through the preset gate runner. After the glute-iron product cools and solidifies, the injection molded glute-iron product is ejected from the mold cavity using ejector pins. Currently, after the plastic-framed iron products are formed in the plastic-framed iron injection mold, they are ejected by a slider ejector. However, when the slider is removed, the plastic-framed iron products are easily stuck to the slider, which means that the appearance needs to be re-trimmed after ejection, resulting in low production quality.

[0003] Therefore, it is necessary to invent a spring block positioning structure to prevent sticking of glued iron products and solve the above problems. Utility Model Content

[0004] (a) Purpose of the utility model To address the technical problems existing in the background art, this utility model proposes a spring block positioning structure for preventing sticking of tinplate products. By setting spring blocks at both ends of the slider, when the slider is removed, the spring blocks can support and position the four corners of the tinplate product, preventing it from sticking to the inner wall of the slider. This ensures the integrity of the appearance of the tinplate product after molding, eliminating the need for further trimming and improving production quality.

[0005] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a spring block positioning structure for preventing sticking of glued iron products, including a front mold, wherein a front mold core is installed at the bottom of the front mold; A rear mold is disposed at the bottom of the front mold, and a rear mold core is installed on the top of the rear mold. A mold cavity for molding plastic iron products is formed between the rear mold core and the front mold core. There are two sliders, which are respectively installed on the front and rear sides of the rear mold core and can slide towards the mold cavity; Four spring blocks are provided, which are respectively installed at the left and right ends of two spring blocks to support the four corners of the plastic iron product; Four springs are provided, which are respectively located inside the left and right ends of the two sliders. The end of each spring near the mold cavity is in contact with the outer wall of its adjacent spring block, so as to keep the position of the spring block unchanged and to position the plastic iron product.

[0006] Preferably, four base pillars are installed at the bottom of the front mold, and the top of each base pillar is inclined towards the center of the rear mold core.

[0007] Preferably, both of the two sliders are provided with heightening blocks on the top left and right sides, and the four base pillars pass downward through the heightening blocks and extend into the interior of the sliders.

[0008] Preferably, both sliders have oblique holes at their top for inserting the base column. The angle of the oblique holes is adapted to the base column. When the front mold core and the rear mold core separate, the base column can drive the two sliders to slide outward from the mold cavity to move away from the plastic iron product.

[0009] Preferably, the inner walls of both sliders located at the springs are provided with blind holes for accommodating the springs.

[0010] Preferably, each of the spring blocks has a limiting hole at its top, and the tops of the two sliders at the spring blocks are connected to limiting blocks, with each limiting block disposed inside the limiting hole adjacent to it.

[0011] Preferably, each of the spring blocks has a groove or protrusion adapted to the mold cavity at the top of the end near the rear mold core.

[0012] Compared with the prior art, the beneficial effects of the above-mentioned technical solution of this utility model are: This invention features spring blocks at both ends of a slider. When the slider is removed, the spring blocks remain in place under the action of springs, providing support and positioning for the four corners of the plastic-coated iron product. This prevents the product from shifting due to the slider's removal and avoids it sticking to the inner wall of the slider. Consequently, when the ejector pin ejects the plastic-coated iron product, its appearance remains intact, eliminating the need for further adjustments and improving production quality.

[0015] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0016] This utility model provides, for example Figure 1-6 The illustrated spring block positioning structure for preventing sticking of plastic iron products includes a front mold 1, and a front mold core 2 is installed at the bottom of the front mold 1. The rear mold 3 is located at the bottom of the front mold 1, and the rear mold core 4 is installed on the top of the rear mold 3. A mold cavity for molding plastic iron products is formed between the rear mold core 4 and the front mold core 2. Two sliders 5 are provided, which are respectively installed on the front and rear sides of the rear mold core 4 and can slide towards the mold cavity; Four spring blocks 6 are provided, which are respectively installed at the left and right ends of two spring blocks 6 to support the four corners of the plastic iron product; Four springs 7 are provided, which are respectively located inside the left and right ends of the two sliders 5. The end of each spring 7 near the mold cavity is in contact with the outer wall of its adjacent spring block 6, so as to keep the position of the spring block 6 unchanged and to position the plastic iron product.

[0017] In one embodiment, four base pillars 8 are installed at the bottom of the front mold 1, and the top of each base pillar 8 is inclined towards the center of the rear mold core 4. The top left and right sides of the two sliders 5 are provided with raising blocks 9. The four base pillars 8 pass downward through the raising blocks 9 and extend into the interior of the sliders 5. The top of the two sliders 5 is provided with inclined holes for the insertion of the base pillars 8. The inclination angle of the inclined holes is adapted to the base pillars 8. When the front mold core 2 and the rear mold core 4 are separated, the base pillars 8 can drive the two sliders 5 to slide outward from the mold cavity to move away from the plastic product. When the base pillars 8 move upward with the front mold 1, they can drive the two sliders 5 away from the center of the mold cavity, thereby moving away from the periphery of the plastic product, so that the periphery is no longer wrapped and the clamping force is reduced.

[0018] In one embodiment, the inner walls of both sliders 5 located at the spring 7 are provided with blind holes for accommodating the spring 7, so that the spring 7 can apply elastic force to the spring block 6. Each spring block 6 has a limiting hole at its top, and the tops of both sliders 5 located at the spring block 6 are connected to limiting blocks 10. Each limiting block 10 is disposed inside the limiting hole adjacent to it. The limiting block 10 can limit the spring block 6, so that when the spring block 6 moves, the inner wall can fit against the outer side of the limiting plate, so that no displacement is detected when moving.

[0019] In one embodiment, each of the spring blocks 6 has a groove or protrusion adapted to the mold cavity at one end near the rear mold core 4, which participates in the formation of the mold cavity and is part of the mold cavity composition for molding of plastic iron products.

[0020] The specific implementation method is as follows: When using this utility model, the steel plate used for molding is placed directly in the mold cavity, and then the molten glue is injected into the mold cavity through the gate of the front mold 1. After the molten glue cools and solidifies, that is, when the plastic iron product is formed, the front mold 1 begins to move away from the rear mold 3, so that the parting surface opens. At this time, due to the upward movement of the front mold 1, each base column 8 is driven to move upward. Due to the inclined design of the base column 8, when it moves vertically upward, it will decompose a horizontal pulling force away from the center of the mold cavity in the inclined hole, so that the two sliders 5 slide outward synchronously away from the mold cavity, and then away from the periphery of the plastic iron product. The periphery of the plastic iron product is no longer wrapped by the sliders 5, there is no obstruction, and the clamping force on the plastic iron product is effectively reduced. When the slider 5 moves away from the mold cavity, the space for the spring block 6 to move in the blind hole increases, and it will automatically extend and then abut against the outside of the spring block 6, so that the position of the spring block 6 can remain unchanged, supporting and positioning the four corners of the plastic iron product, keeping it in its initial position, thereby preventing the plastic iron product from moving as the slider 5 is removed, and preventing it from sticking to the inner wall of the slider 5. Subsequently, the plastic iron product is pushed upward from the mold cavity by the ejector pins inside the rear mold 3, and can be removed by the staff to complete the production of the plastic iron product. After molding, the plastic iron product will not stick to the slider 5, and the appearance is relatively complete after ejection, without the need for further repair, thus improving the production quality and molding quality. This embodiment specifically solves the problem in the prior art that, after the plastic iron products are formed in the plastic iron injection mold, the plastic iron products are ejected by the slide block 5. However, when the slide block 5 is removed, the plastic frame products are easy to stick to the slide block 5, which means that the appearance needs to be re-trimmed after ejection, resulting in low production quality.

[0022] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
