The special mold for packaging brackets includes a fixed mold and a moving mold. A slider is slidably mounted on the surface of the moving mold, and a pressure plate is fixed to the side of the fixed mold corresponding to the slider. The slider and pressure plate are symmetrically arranged. When the fixed mold and the moving mold approach each other, the pressure plate squeezes the inner slider, achieving the purpose of squeezing the slider inward to form an arc-shaped plate structure. A slider is slidably mounted inside the mold, and in conjunction with the contact between the moving mold and the fixed mold, the fixed pressure plate squeezes the slidably mounted slider. This allows the mold itself to be larger than required to accommodate the flow needs of molten material injection. The slider squeezes inward to form an arc-shaped injection structure. On the one hand, a larger flow channel facilitates the injection molding of complex structures, and on the other hand, the squeezing action removes air bubbles from inside the molten material, ensuring the strength requirements of the molded part.

Description

Technical Field

[0001] This utility model proposes a special mold, which relates to the field of natural gas pipeline packaging technology, specifically to a special mold for packaging brackets. Background Technology

[0002] To avoid problems such as messy placement or even mutual compression of oil and gas pipelines during transportation, the pipelines are usually packaged and secured with packaging supports before transportation. Existing packaging supports mainly consist of a main body and an arc-shaped plate that fits against the pipeline. The main bodies can be connected in parallel, and the pipeline is secured by the arc-shaped plate.

[0003] Existing brackets are usually made of rigid plastic and produced by injection molding. However, the structure of the packaging bracket is relatively complex, with many parts using hollow structures. Ordinary injection molds cannot form it in one step. After injection molding, the side plates need to be heated by heating equipment for a second molding operation to produce the arc-shaped plate bracket with open ends. The production process is complicated. In addition, the injection molding process generally produces many small air bubbles in the injection molded parts, which affects the quality of the molded parts.

[0004] Therefore, those skilled in the art propose a special mold for packaging brackets. In order to meet the injection molding needs of packaging brackets that are large in volume and have hollow arc-shaped structures at both ends, a special mold is designed to facilitate one-time molding and make production convenient. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a special mold for packaging brackets. Symmetrical and slidably mounted sliders on both sides compress the middle mold. The injection mold itself has a slightly larger internal width to facilitate injection molding of complex internal structures. As the fixed mold and moving mold approach each other, the pressure plate fixed on the side of the fixed mold compresses the slidably mounted sliders. This not only compresses the mold, which is originally slightly larger than the actual required size, into a size that meets the specifications, but also helps to eliminate internal air bubbles and ensure the quality of the molded parts.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a special mold for packaging brackets, comprising a fixed mold and a moving mold, wherein the fixed mold and the moving mold are combined to form a complete mold to meet the injection molding requirements.

[0007] The upper surface of the moving mold is slidably equipped with sliders. As the fixed mold and the moving mold approach each other, the two symmetrically arranged sliders squeeze and shape the material in the fixed mold towards the center, making the size slightly larger than the actual need, and appropriately widening the injection channel to facilitate the compression of the fixed mold into the actual required size, and removing air bubbles during the compression process.

[0008] A pressure plate is fixed to the side of the fixed mold. The pressure plate is symmetrically fixed to the corresponding slider. One end of the pressure plate is fixed to the side wall of the fixed mold, and the other end extends outward a certain distance to obtain a certain elasticity. The pressure plates on both sides slide towards the middle as the fixed mold and the moving mold approach each other.

[0009] Preferably, the upper surface of the moving mold is provided with a groove, and the slider is symmetrically arranged on the upper surface of the moving mold through the groove. Within a certain distance range, the slider can slide along the groove on the surface of the moving mold to extrude the injection molded part inside the mold.

[0010] A sealing strip is fixed to the upper surface of the moving mold corresponding to the slider. The slider is installed by limiting the sealing strip. The sealing strip protrudes from the surface of the moving mold and works with the slider to prevent leakage of the molten injection and to limit the sliding range of the slider.

[0011] Preferably, the two sliders are configured with a trapezoidal slope that is smaller at the top and larger at the bottom on the side away from each other. The trapezoidal slope facilitates the pressure plate pressing the sliders when the fixed mold and the moving mold are close to each other.

[0012] The two sliders are positioned close to each other and are configured with an arc-shaped extrusion surface. The arc-shaped extrusion surface, together with the fixed mold, forms a packaging bracket with an arc-shaped surface.

[0013] Preferably, the fixed mold has an alignment hole on its inner side, and the moving mold has a guide post fixed to the alignment hole at one end near the fixed mold. The fixed mold and the moving mold are guided and installed through the guide post.

[0014] During injection molding, molten material is injected into the moving mold, and then the moving mold is moved closer to the fixed mold. The alignment hole on the inner side of the fixed mold will not affect the injection molding, and it works with the guide post to guide the mold closing.

[0015] Preferably, one end of the pressure plate is fixedly connected to the fixed mold, and the inner side of the other end of the two pressure plates is provided with an inclined extrusion surface corresponding to the slider. As the fixed mold and the moving mold approach each other, the extended ends of the pressure plates contact the outer wall of the slider and extrude it, driving the slider to extrude the mold itself towards the center.

[0016] The fixed mold and the moving mold are symmetrically fixed with fixed blocks on their inner sides. The fixed blocks are pressed against the inner cavity of the mold, and together with the slider, they form a hollow arc-shaped plate structure by extruding from the outside to the inside.

[0017] This utility model discloses a special mold for packaging brackets, which has the following beneficial effects:

[0018] This special mold for packaging brackets features a sliding slider installed inside the mold. In conjunction with the contact between the moving mold and the fixed mold, a fixed pressure plate compresses the sliding slider, resulting in a mold size that is larger than required to accommodate the flow of the molten material during injection molding. The slider is then used to compress the material inward to form an arc-shaped injection structure. This allows for the injection molding of complex structures with a larger flow channel, facilitating the process. Furthermore, the extrusion action removes air bubbles from the molten material, ensuring the strength requirements of the molded part are met. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] This utility model embodiment discloses a special mold for a packaging bracket;

[0026] According to the appendix Figure 1-3 As shown, it includes a fixed mold 1 and a moving mold 2. The fixed mold 1 and the moving mold 2 are used to close the mold to form a complete mold to meet the injection molding requirements.

[0027] The upper surface of the moving mold 2 is slidably equipped with sliders 3. As the fixed mold 1 and the moving mold 2 approach each other, the two symmetrically arranged sliders 3 squeeze and shape the material in the fixed mold 1 towards the center, making the size slightly larger than the actual need, and appropriately widening the injection channel to facilitate the compression of the fixed mold 1 into the actual required size, and removing air bubbles in the compression process.

[0028] A pressure plate 4 is fixed on the side of the fixed mold 1. The pressure plate 4 is symmetrically fixed to the slider 3. One end of the pressure plate 4 is fixed to the side wall of the fixed mold 1, and the other end extends outward a certain distance to obtain a certain elasticity. As the fixed mold 1 and the moving mold 2 approach each other, the pressure plates 4 on both sides squeeze the slider 3 and slide towards the middle.

[0029] The upper surface of the moving mold 2 is provided with a groove 5, and the slider 3 is symmetrically arranged on the upper surface of the moving mold 2 through the groove 5. Within a certain distance range, the slider 3 can slide along the groove 5 on the surface of the moving mold 2 to extrude the injection molded part inside the mold.

[0030] A sealing strip 6 is fixed on the upper surface of the moving mold 2 corresponding to the slider 3. The slider 3 is installed by limiting the sealing strip 6. The sealing strip 6 protrudes from the surface of the moving mold 2, and works with the slider 3 to prevent leakage of the molten injection and to limit the sliding range of the slider 3.

[0031] The two sliders 3 are set to a trapezoidal slope with a smaller top and a larger bottom on one side away from each other. The trapezoidal slope facilitates the pressure plate 4 to squeeze the sliders 3 when the fixed mold 1 and the moving mold 2 are close to each other.

[0032] The two sliders 3 are positioned close to each other and are set as arc-shaped extrusion surfaces. The arc-shaped extrusion surfaces work together with the fixed mold 1 to form a packaging bracket with an arc-shaped surface.

[0033] The fixed mold 1 has an alignment hole 7 on its inner side. The moving mold 2 has a guide post 8 fixed at one end near the fixed mold 1, corresponding to the alignment hole 7. The fixed mold 1 and the moving mold 2 are guided and installed through the guide post 8.

[0034] During injection molding, molten material is injected into the moving mold 2, and then the moving mold 2 is moved closer to the fixed mold 1. The alignment hole 7 on the inner side of the fixed mold 1 will not affect the injection molding, and it is guided by the guide post 8 for mold closing.

[0035] One end of the pressure plate 4 is fixedly connected to the fixed mold 1. The inner side of the other end of the two pressure plates 4 is provided with an inclined extrusion surface corresponding to the slider 3. As the fixed mold 1 and the moving mold 2 approach each other, the extended ends of the pressure plates 4 contact the outer wall of the slider 3 and extrude it, driving the slider 3 to extrude the mold itself towards the middle.

[0036] Fixed blocks 9 are symmetrically fixed on the inner sides of the fixed mold 1 and the moving mold 2. The fixed blocks 9 are pressed against the inner cavity of the mold, and together with the slider 3, they form a hollow arc plate structure by extruding from the outside to the inside.

[0037] A sliding block 3 is installed inside the mold. In conjunction with the contact between the moving mold 2 and the fixed mold 1, the sliding block 3 is squeezed by the fixed pressure plate 4. This makes the mold itself larger to meet the flow requirements of the molten injection. The sliding block 3 is squeezed inward to form an arc-shaped injection structure. On the one hand, the complex structure is injected with a larger flow channel, which facilitates the process. On the other hand, the squeezing action removes air bubbles inside the molten material, ensuring the strength requirements of the molded part.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
