Description

Technical Field

[0001] The utility model belongs to the technical field of injection molds, in particular to an injection mold with a guide structure. Background Art

[0002] Injection molds can be used to produce plastic products. Injection molds can quickly and massively produce plastic products of the same shape and size. When used, molten plastic material is injected into the mold, and the molded plastic product is taken out after cooling and solidification.

[0003] In the prior art, when installing the injection mold, it is necessary to manually align the mold with the mounting holes on the connecting plate. Since the mold is usually heavy, the position of the mold is easily offset during the installation process, making it difficult to align and install it in one go, which is time-consuming and labor-intensive. Summary of the invention

[0004] The purpose of the utility model is to provide an injection mold with a guide structure to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solution: an injection mold with a guide structure, comprising an upper connecting plate, an upper mold, a lower connecting plate, a lower mold and an injection hole, the upper mold is installed at the bottom of the upper connecting plate, the lower connecting plate is arranged below the upper mold, the lower mold is installed on the surface of the lower connecting plate, and the injection hole is opened inside the lower mold.

[0006] Preferably, the top of the upper mold and the bottom of the lower mold are both connected to guide blocks, the top of the upper connecting plate and the bottom of the lower connecting plate are both welded with fixed blocks, the surface of the fixed block is welded with connecting blocks, the inside of the fixed block is connected to a bidirectional screw rod through a bearing, and the outer side of the bidirectional screw rod is threadedly connected to a slider.

[0007] Preferably, the end of the slider is connected to a moving block, a clamping block is welded on the side of the moving block close to the guide block, a first gear is welded on the outside of the bidirectional screw rod, the inside of the connecting block is connected to a rotating rod through a bearing, and a second gear is welded on the outside of the rotating rod.

[0008] Preferably, a meshing structure is formed between the second gear and the first gear, and a clamping structure is formed between the clamping block and the guide block.

[0009] Preferably, a mounting block is welded to the bottom of the upper connecting plate, and a spring is connected inside the mounting block.

[0010] Preferably, one end of the spring is connected to a stopper, and both sides of the stopper are connected to limit blocks.

[0011] Preferably, a fixing rod is welded on the surface of the lower connecting plate, and the end of the fixing rod is connected to a fixing plate.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. When the upper mold of the utility model moves, it drives the guide block to move. When the top of the upper mold moves to the bottom of the upper connecting plate, the guide block will penetrate the upper connecting plate. When the rotating rod rotates, it drives the second gear to rotate, and the second gear drives the first gear to mesh and rotate. The first gear drives the two-way screw to rotate, and the two-way screw drives the two sets of sliders to slide threads close to each other. When the moving block moves, it drives the card block to move. When the end of the card block is inserted into the inside of the guide block, the inclined surface of the card block will engage and dock with the guide block. When installing the lower mold, you only need to pass the guide block on the lower mold through the lower connecting plate. The subsequent operation method is the same as the installation method of the upper mold. The guide block plays a guiding role in the process of installing the upper mold, so that the position of the upper mold is not easy to shift, and the installation operation can be carried out quickly, thereby improving the efficiency of replacing the mold.

[0014] 2. When the bottom of the upper mold drops to the top surface of the lower mold, the mounting block will move to the outside of the fixed rod. At this time, the fixed plate will squeeze the block, and when the block moves, it will compress the spring, thereby playing a buffering role to prevent a large degree of collision when the upper mold and the lower mold are docked, thereby reducing the degree of damage to the surface of the upper mold and the lower mold.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figures 1 to 3 It can be seen that the utility model provides a technical solution: an injection mold with a guide structure, including an upper connecting plate 1, an upper mold 2, a lower connecting plate 3, a lower mold 4 and an injection hole 5, the upper mold 2 is installed at the bottom of the upper connecting plate 1, the lower connecting plate 3 is arranged below the upper mold 2, the lower mold 4 is installed on the surface of the lower connecting plate 3, the injection hole 5 is opened inside the lower mold 4, the top of the upper mold 2 and the bottom of the lower mold 4 are both connected with a guide block 6, the top of the upper connecting plate 1 and the bottom of the lower connecting plate 3 are both welded with a fixing block 7, and the surface of the fixing block 7 A connecting block 8 is welded, and a bidirectional screw rod 9 is connected to the inside of the fixed block 7 through a bearing. A slider 10 is threadedly connected to the outer side of the bidirectional screw rod 9, and a moving block 11 is connected to the end of the slider 10. A clamping block 12 is welded to the side of the moving block 11 close to the guide block 6, and a first gear 13 is welded to the outer side of the bidirectional screw rod 9. A rotating rod 14 is connected to the inside of the connecting block 8 through a bearing, and a second gear 15 is welded to the outer side of the rotating rod 14. A meshing structure is formed between the second gear 15 and the first gear 13, and a clamping structure is formed between the clamping block 12 and the guide block 6.

[0023] When the utility model is used, the upper mold 2 is pushed to move, driving the guide block 6 to move. When the top of the upper mold 2 drops to the bottom of the upper connecting plate 1, the guide block 6 will penetrate the upper connecting plate 1. At this time, the rotating rod 14 can be rotated to drive the second gear 15 to rotate, and the second gear 15 drives the first gear 13 to mesh and rotate. The first gear 13 drives the two-way screw rod 9 to rotate, and the rotation of the two-way screw rod 9 drives the two sets of sliders 10 to slide the threads close to each other. The slider 10 drives the moving block 11 to move, and the moving block 11 drives the clamping block 12 to move. When the end of the clamping block 12 is inserted into the guide block 6, the inclined surface of the clamping block 12 will engage and dock with the guide block 6, so that the upper mold 2 can be quickly installed on the bottom of the upper connecting plate 1; when installing the lower mold 4, it is only necessary to pass the guide block 6 on the lower mold 4 through the lower connecting plate 3, and the subsequent operation method is the same as the installation method of the upper mold 2.

[0024] See also Figures 1 to 3 It can be seen that the guide block 6 plays a guiding role during the installation of the upper mold 2, so that the position of the upper mold 2 is not easily offset, and the installation operation can be carried out quickly, thereby improving the efficiency of mold replacement.

[0025] See also Figure 1 , Figure 2 and Figure 4 It can be seen that a mounting block 16 is welded to the bottom of the upper connecting plate 1, a spring 17 is connected to the inside of the mounting block 16, one end of the spring 17 is connected to a stopper 18, and both sides of the stopper 18 are connected to limiting blocks 19. A fixing rod 20 is welded to the surface of the lower connecting plate 3, and a fixing plate 21 is connected to the end of the fixing rod 20, and a sliding structure is formed between the fixing plate 21 and the mounting block 16.

[0026] During specific implementation, when the upper connecting plate 1 drives the upper mold 2 to descend, it drives the mounting block 16 to move. When the bottom of the upper mold 2 drops to the top of the lower mold 4, the mounting block 16 will move to the outside of the fixed rod 20. At this time, the fixed plate 21 will squeeze the stopper 18. When the stopper 18 is squeezed, it drives the limit block 19 to move. When the stopper 18 moves, it compresses the spring 17, thereby playing a buffering role to prevent a large degree of collision when the upper mold 2 and the lower mold 4 are docked.

[0027] See also Figure 1 , Figure 2 and Figure 4 It can be seen that the spring 17 plays a certain buffering effect during the descent of the upper mold 2, thereby reducing the degree of damage to the surfaces of the upper mold 2 and the lower mold 4.

[0028] In summary, when the utility model is used, when the upper mold 2 is docked with the lower mold 4, the molten plastic is injected into the lower mold 4 through the injection hole 5, so that the molten plastic fills the interior of the upper mold 2 and the lower mold 4. After the molten plastic is cooled and formed, the upper mold 2 is lifted and opened to be taken out. No further description is given here. When installing the lower mold 4, it is only necessary to pass the guide block 6 on the lower mold 4 through the lower connecting plate 3. The subsequent operation method is the same as the installation method of the upper mold 2. The guide block 6 plays a guiding role in the installation process of the upper mold 2, so that the position of the upper mold 2 is not easy to shift, and the installation operation can be carried out quickly, thereby improving the efficiency of replacing the mold; when the spring 17 is compressed, it can play a buffering role to prevent a large degree of collision when the upper mold 2 and the lower mold 4 are docked, thereby reducing the degree of damage to the surface of the upper mold 2 and the lower mold 4.
