Technical Field
[0001] This utility model relates to the field of injection molding mold technology, specifically a fixing device for injection molding molds. Background Technology
[0002] Injection molding, also known as injection molding, is a molding method that combines injection and molding. The advantages of injection molding are fast production speed, high efficiency, automated operation, a wide variety of colors and patterns, shapes ranging from simple to complex, sizes ranging from large to small, precise product dimensions, easy product updates and replacements, and the ability to produce complex-shaped parts.
[0003] For example, application number CN202221610572.8 relates to the field of injection mold technology and discloses a fixing component for injection molding, including a device body. The device body includes a frame and a base plate. A support plate is installed on the top of the frame, and a pressure plate is installed below the hydraulic cylinder. Slide grooves are opened on both sides of the center of one end of the base plate. Connecting rings are installed at both ends of the push plate. A drive rod is installed inside the drive tube, and a support seat is installed on one side of the fixing plate. This fixing component for injection molding utilizes the connection relationship between the frame and the base plate to form a stable frame structure. The injection mold is placed inside the frame and below. Pushing the push plate activates the hydraulic cylinder to drive the pressure plate to press down, improving the stability of the injection mold during fixing. The push plate fixes the bottom of the injection mold. By rotating the drive rod, the connecting rings and push plate are moved through the thread, thereby effectively controlling the push plate to clamp and fix the injection mold, and facilitating the replacement of the injection mold.
[0004] Based on the search of the aforementioned patents and the findings of existing equipment, while the aforementioned equipment can solve the problems of traditional injection molding machines where the injection mold is a single unit, making it inconvenient to fix and resulting in poor fixing effect, and the welding fixing method which makes mold replacement inconvenient, different molding specifications are often equipped with different mold sizes. When changing molds, due to the difference in fixing methods, direct fixing is not possible, and it is often necessary to change the clamps simultaneously, i.e., disassemble and replace the corresponding mold fixing device, which leads to extended replacement time and increased workload.

Therefore, it is often necessary to change the clamps at the same time, that is, to remove and replace the corresponding mold fixing device, which leads to the extension of replacement time and the increase of workload.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a fixing device for injection molding molds, comprising a frame, a push plate, a base, and a support base. The frame is fixedly connected to the top of the base, the support base is fixedly connected to the rear side of the top of the base, the push plate is movably connected to the front side of the top of the base, and first sliding grooves are provided on both sides of the top of the push plate and both sides of the top of the support base. A fixing plate is provided on the top of the first sliding groove, and a first slider is fixedly connected to the bottom of the fixing plate. The first slider is slidably connected to the first sliding groove, and a positioning mechanism is provided inside the first sliding groove.
[0007] In a preferred embodiment of this utility model, the positioning mechanism includes a groove, a first spring, a positioning element, and a positioning slot. The groove is formed inside the first slider, the first spring is inside the groove, the positioning element is fixedly connected to the other end of the first spring, and the positioning slot is formed on the side of the first slide near the groove. Several positioning slots are provided and are distributed in a rectangular shape at equal intervals. The positioning element is movably connected to the positioning slot.
[0008] In a preferred embodiment of this invention, a second sliding groove is provided on the outer side of the slider, a fixed rod is fixedly connected to the outer side of the positioning member, the fixed rod is slidably connected to the second sliding groove, a rocker arm is movably connected to the outer side of the first slider, a third sliding groove is provided on the outer side of the rocker arm, and the fixed rod is slidably connected to the third sliding groove.
[0009] In a preferred embodiment of this invention, a movable rod is movably connected inside the first slide groove, and a protruding plate is fixedly connected to the surface of the movable rod.

An arc-shaped groove is formed at the bottom of the outer side of the first slider, and the protruding plate is movably connected to the arc-shaped groove.
[0010] As a preferred embodiment of this utility model, a fixing member is fixedly connected to the outer side of the surface of the movable rod, and fixing blocks are fixedly connected to both sides of the top of the support base and both sides of the top of the push plate. A positioning hole is opened on the inner side of the fixing block, and a pin is movably connected to the inner side of the fixing member.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] 1. This utility model, by setting a first sliding groove, a fixed plate, and a first slider, moves the first slider inside the first sliding groove, and then causes the first slider to drive the fixed plate to move. This allows the fixed plate to fix molds of different sizes by moving from the inside to the outside. This solves the problem that different molding specifications are often equipped with molds of different sizes, and when changing molds, they cannot be directly fixed due to differences in fixing methods. It is often necessary to change the clamps at the same time, that is, to remove and replace the corresponding mold fixing device, which leads to extended replacement time and increased workload. This utility model has the advantage of mold fixing adjustment.
[0015] 2. This utility model, by setting a positioning mechanism, when it is necessary to adjust the fixing plate to fix the mold for replacement, causes the first slider to move the positioning component and the fixing plate inside the first slide groove. Then, when it moves to the appropriate position, the first spring inside the groove is compressed and released, causing the positioning component to move. After that, the positioning component is inserted into the corresponding positioning groove, so that the positioning component and the positioning groove cooperate to position the first slider, thereby completing the adjustment and fixing of the fixing plate. Furthermore, by setting a second slide groove, a fixing rod, a rocker arm, and a third slide groove, when it is necessary to release the positioning of the first slider, by rotating the rocker arm, the fixing rod inside the third slide groove opened by the rocker arm moves the positioning component. Then, the fixing rod inside the second slide groove causes the positioning component to compress and contract the first spring, thereby causing the positioning component to detach from the positioning groove and retract into the groove, thus releasing the fixing of the first slider.
[0016] 3. This utility model, by setting a movable rod, a convex plate, and an arc-shaped groove, allows the rocker arm to rotate when the movable rod is rotated, causing the convex plate to rotate. The convex plate then drives the rocker arm to rotate inside the arc-shaped groove, thus completing the rotation of the rocker arm by the movable rod. Furthermore, by setting a fixing component, a fixing block, a positioning hole, and a pin, to prevent the first slider from continuously rotating the movable rod and retracting the positioning component during adjustment, the fixing component is fixedly connected to the surface of the movable rod. Then, the fixing component drives the pin to align with the positioning hole of the fixing block. Afterward, the positioning component is inserted into the positioning hole to fix the fixing component and prevent rotation. At the same time, the fixing component is fixed by moving the rocker arm.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] like Figures 1 to 4 As shown, the present invention provides a fixing device for injection molding molds, including a frame 1, a push plate 2, a base 3, and a support base 4. The frame 1 is fixedly connected to the top of the base 3, the support base 4 is fixedly connected to the rear side of the top of the base 3, the push plate 2 is movably connected to the front side of the top of the base 3, and first sliding grooves 5 are provided on both sides of the top of the push plate 2 and both sides of the top of the support base 4. A fixing plate 6 is provided on the top of the first sliding groove 5, and a first slider 7 is fixedly connected to the bottom of the fixing plate 6. The first slider 7 is slidably connected to the first sliding groove 5, and a positioning mechanism 8 is provided inside the first sliding groove 5.
[0024] refer to Figure 4 The positioning mechanism 8 includes a groove 81, a first spring 82, a positioning element 83, and a positioning slot 84. The groove 81 is opened inside the first slider 7, the first spring 82 is inside the groove 81, the positioning element 83 is fixedly connected to the other end of the first spring 82, and the positioning slot 84 is opened on the side of the first slide 5 near the groove 81. Several positioning slots 84 are provided and are distributed in a rectangular shape at equal intervals. The positioning element 83 is movably connected to the positioning slot 84.
[0025] As a technical optimization of this utility model, by setting a positioning mechanism 8, when it is necessary to adjust the fixing plate 6 to fix the mold to be replaced, the first slider 7 drives the positioning part 83 and the fixing plate 6 to move inside the first slide groove 5. Then, when the appropriate position is reached, the first spring 82 is squeezed and compressed inside the groove 81 to release the pressure and drive the positioning part 83 to move. Then, the positioning part 83 is inserted into the corresponding positioning groove 84, so that the positioning part 83 and the positioning groove 84 cooperate to position the first slider 7, thereby completing the adjustment and fixing of the fixing plate 6.
[0026] refer to Figure 3 The outer side of the slider is provided with a second sliding groove 9, and the outer side of the positioning member 83 is fixedly connected with a fixing rod 10. The fixing rod 10 is slidably connected to the second sliding groove 9. The outer side of the first slider 7 is movably connected with a rocker arm 11. The outer side of the rocker arm 11 is provided with a third sliding groove 12, and the fixing rod 10 is slidably connected to the third sliding groove 12.
[0027] As a technical optimization of this utility model, by setting a second slide groove 9, a fixing rod 10, a rocker arm 11 and a third slide groove 12, when it is necessary to release the positioning of the first slider 7, by rotating the rocker arm 11, the fixing rod 10 inside the third slide groove 12 opened by the rocker arm 11 drives the positioning member 83 to move. Then, the fixing rod 10 inside the second slide groove 9 drives the positioning member 83 to squeeze and contract the first spring 82, thereby causing the positioning member 83 to disengage from the positioning groove 84 and retract into the groove 81 to complete the release of the fixing of the first slider 7.
[0028] refer to Figure 3 The first slide groove 5 is movably connected to a movable rod 13. A protruding plate 14 is fixedly connected to the surface of the movable rod 13. The slider and the rocker arm 11 are both sleeved on the surface of the movable rod 13. An arc-shaped groove 15 is opened at the bottom of the outer side of the first slider 7. The protruding plate 14 is movably connected to the arc-shaped groove 15.
[0029] As a technical optimization of this utility model, by setting up a movable rod 13, a convex plate 14 and an arc-shaped groove 15, when rotating the rocker arm 11, the movable rod 13 can be rotated to drive the convex plate 14 to rotate, and then the convex plate 14 drives the rocker arm 11 to rotate inside the arc-shaped groove 15, so that the movable rod 13 rotates to complete the rotation of the rocker arm 11.
[0030] refer to Figure 2 A fixing member 16 is fixedly connected to the outer side of the surface of the movable rod 13. Fixing blocks 17 are fixedly connected to both sides of the top of the support base 4 and both sides of the top of the push plate 2. A positioning hole 18 is opened on the inner side of the fixing block 17. A pin 19 is movably connected to the inner side of the fixing member 16.
[0031] As a technical optimization of this utility model, by setting a fixing member 16, a fixing block 17, a positioning hole 18 and a pin 19, in order to prevent the first slider 7 from continuously rotating the movable rod 13 to retract the positioning member 83 during the movement and adjustment, the fixing member 16 is fixedly connected to the surface of the movable rod 13. Then, the fixing member 16 drives the pin 19 to align with the positioning hole 18 of the fixing block 17. After that, the positioning member 83 is inserted into the positioning hole 18 to fix the fixing member 16 to prevent rotation. At the same time, the fixing member 16 is fixed by moving the rocker arm 11.
[0032] refer to Figure 4A telescopic rod 20 is fixedly connected to the side of the groove 81 away from the positioning member 83. The other end of the telescopic rod 20 is fixedly connected to the end of the positioning member 83 near the first spring 82. The first spring 82 is sleeved on the surface of the telescopic rod 20.
[0033] As a technical optimization of this utility model, by setting the telescopic rod 20, the stability and safety of the first spring 82 are increased, and the first spring 82 is prevented from twisting and being damaged when squeezed and contracted, thereby extending the service life of the first spring 82.
[0034] refer to Figure 3 A second spring 21 is fixedly connected to the back of the fastener 16, and a fixing ring 22 is fixedly connected to the surface of the pin 19. The other end of the second spring 21 is fixedly connected to the outside of the fixing ring 22.
[0035] As a technical optimization of this utility model, by setting a second spring 21 and a fixing ring 22, in order to prevent the pin 19 from falling out when it is not inserted into the positioning hole 18, the second spring 21 is stretched to drive the fixing ring 22 to move, and then the fixing ring 22 drives the pin 19 to disengage from the positioning hole 18, and finally the end of the pin 19 close to the fixing block 17 contacts the inner side of the fixing block 17.
[0036] The working principle and usage process of this utility model are as follows: When it is necessary to replace the mold adjustment fixing plate 6, rotate the fixing part 16, causing the fixing part 16 to drive the movable rod 13 to rotate, which in turn drives the convex plate 14 to rotate. Then, the convex plate 14 drives the rocker arm 11 to rotate inside the arc groove 15. After that, when the rocker arm 11 is rotated, the fixing rod 10 inside the third slide groove 12 of the rocker arm 11 drives the positioning part 83 to move. Then, the fixing rod 10 inside the second slide groove 9 drives the positioning part 83 to compress and contract the first spring 82. At the same time, the pin 19 is connected to the positioning hole 18, causing the second spring 21 to release its tensile tension and drive the fixing ring 22 to move, causing the fixing ring 22 to drive the pin 19 to move. Pin 19 moves and inserts into the positioning hole 18, thereby causing the positioning member 83 to disengage from the positioning groove 84 and retract into the groove 81, thus unfixing the first slider 7. Finally, the first slider 7 moves and adjusts the positioning member 83 and the fixing plate 6 within the first slide groove 5. After adjustment, the second spring 21 is stretched, causing the fixing ring 22 to move. Then, the fixing ring 22 moves the pin 19 out of the positioning hole 18. Finally, the end of the pin 19 near the fixing block 17 contacts the inside of the fixing block 17. At the same time, the first spring 82 is released from its restraint and squeezes, causing the positioning member 83 to insert into the corresponding positioning groove 84, thus completing the movement adjustment of the fixing plate 6. This achieves the advantage of mold fixing adjustment.
[0037] In summary, this injection molding die fixing device, through the setting of a first sliding groove 5, a fixing plate 6, and a first slider 7, allows the first slider 7 to move inside the first sliding groove 5, thereby causing the fixing plate 6 to move. This allows the fixing plate 6 to fix molds of different sizes by moving from the inside to the outside, solving the problem that different molding specifications are often equipped with different mold sizes, and when changing molds, the different fixing methods make it impossible to fix them directly. This often requires simultaneous replacement of the clamps, i.e., disassembling and replacing the corresponding mold fixing device, which leads to extended replacement time and increased workload.
