Description

Technical Field

[0001] This invention relates to a special fixture for injection mold production, and more particularly to a high-efficiency clamping fixture for injection mold production, belonging to the field of fixture technology. Background Technology

[0002] In the injection mold production process, the precise assembly of the mold template and the performance testing of mold opening and closing are crucial steps to ensure mold forming accuracy and extend service life. On the one hand, during the template assembly stage, specialized fixtures are needed to ensure the stable positioning of the moving and fixed molds, preventing displacement or skew during assembly and ensuring that core assembly parameters such as cavity alignment and guide post / sleeve fit meet design requirements. On the other hand, after assembly, horizontal and vertical mold opening and closing tests must be conducted sequentially to verify the smoothness of mold movement, guiding accuracy, and force balance in different opening and closing directions, and to identify potential problems such as interference, jamming, or abnormal fitting gaps.

[0003] However, existing fixtures used in injection mold production generally suffer from fixed shapes and limited functions: most fixtures can only clamp and fix in a single direction (horizontal or vertical), and cannot simultaneously limit the movement and fixed molds, resulting in the need to repeatedly disassemble and assemble the fixtures and adjust the mold placement during testing; moreover, the fixtures lack flexible position adjustment functions, making it difficult to adapt to the clamping requirements of different mold sizes, and they cannot quickly fine-tune the relative positions of the movement and fixed molds according to the test scenario, which not only increases the cumbersomeness of the test operation, but also leads to a longer preparation time and lower efficiency for mold opening and closing tests, seriously affecting the overall cycle time and delivery cycle of mold production.

[0004] To address these issues, a high-efficiency clamping fixture specifically designed for injection mold production was developed. Summary of the Invention

[0005] The main objective of this invention is to provide a high-efficiency clamping fixture specifically designed for injection mold production. Through a combination of a lower flap mounted rotatably at both ends of the base, a horizontally sliding mounting block on the top of the lower flap, and an upper flap structure rotatably mounted on the mounting block, along with a clamping and fixing mechanism on the top of the upper flap, integrated operation of multiple mold processes can be achieved. Without disassembling the mold, the moving and fixed molds can be first fixed to the two sets of upper flaps to complete horizontal assembly. After assembly, simply controlling the rotation of the two sets of upper flaps adjusts the relative horizontal position of the moving and fixed molds, allowing for direct horizontal opening and closing tests. For vertical opening and closing tests, only the simultaneous rotation of the upper and lower flaps at one end of the base is needed to achieve vertical adjustment of the moving and fixed molds. The entire process eliminates the need for repeated fixture changes or mold placement adjustments, enabling flexible conversion between "assembly - horizontal testing - vertical testing." This covers the needs of multiple processes while significantly simplifying the operation, effectively solving the problems of traditional fixtures' limited functionality and poor adaptability. The upper flap's top features a cross-shaped groove and a pneumatic... The clamping and fixing mechanism, composed of a cylinder, vertical plate, horizontal plate, lower pressure plate, and side pressure plate, can achieve a double-sided clamping effect of side extrusion and top extrusion on the edge protrusion structure of the mold mounting base when fixing the moving mold and the fixed mold. The cylinder drives the vertical plate to link with the horizontal plate. The horizontal plate drives the side pressure plate to limit from the side through the vertical groove, slide rod, and connecting rod. At the same time, the lower pressure plate applies pressure from the top. With the buffer compensation of the return spring, multi-dimensional tight limiting is achieved. Compared with traditional single-direction clamping, this structure can effectively avoid displacement and skewing of the mold during assembly or testing, significantly improving clamping stability and ensuring the accuracy of core assembly parameters such as cavity docking and guide post and guide sleeve mating. Through the linear movement mechanism composed of the first linear slide, the first slider, the first conveying motor, and the first screw, during the movement of the mold for horizontal or vertical opening and closing tests, the first conveying motor drives the first screw to drive the mounting block to slide smoothly along the first linear slide, thereby achieving uniform and smooth relative movement of the moving mold and the fixed mold.

One end of the second screw is fixedly connected to the output end of the second conveying motor. The support rod is hinged between the top of the second slider and the bottom of the upper flip plate.

[0015] Preferably, the bottom of the upper flap has a hidden groove along its length, the hinge point at the top of the support rod is located inside the hidden groove, and the width of the hidden groove is greater than the width of the support rod.

[0016] Preferably, the clamping and fixing mechanism includes a cross-shaped slide groove, a cylinder, a vertical plate, and a double-sided clamping assembly.

[0017] Preferably, the double-sided clamping assembly includes a horizontal plate, a vertical groove, a lower pressure plate, a side pressure plate, a slide rod, a horizontal groove, a return spring, and a connecting rod.

[0021] The beneficial effects of this invention are as follows:

[0022] This invention provides a high-efficiency clamping fixture for injection mold production. Through a combination of a lower flap mounted on both ends of the base, a horizontally sliding mounting block on the top of the lower flap, and an upper flap structure rotating on the mounting block, along with a clamping and fixing mechanism on the top of the upper flap, it enables integrated operation of multiple mold processes. Without disassembling the mold, the moving and fixed molds can be first fixed to the two sets of upper flaps to complete horizontal assembly. After assembly, simply controlling the rotation of the two sets of upper flaps adjusts the relative horizontal position of the moving and fixed molds, allowing for direct horizontal opening and closing tests. For vertical opening and closing tests, only the simultaneous rotation of the upper and lower flaps at one end of the base is needed to achieve vertical adjustment of the moving and fixed molds. The entire process eliminates the need for repeated fixture changes or mold placement adjustments, enabling flexible conversion between "assembly-horizontal testing-vertical testing." This covers the needs of multiple processes while significantly simplifying the operation, effectively solving the problems of traditional fixtures' limited functionality and poor adaptability.

[0023] Relying on the clamping and fixing mechanism composed of a cross-shaped groove, cylinder, vertical plate, horizontal plate, lower pressure plate, and side pressure plate at the top of the upper flip plate, when fixing the moving mold and the fixed mold, it can form a double-sided clamping effect of side extrusion and top extrusion on the edge protrusion structure of the mold mounting seat. The cylinder drives the vertical plate to link with the horizontal plate. The horizontal plate drives the side pressure plate to limit from the side through the vertical groove, slide rod, and connecting rod. At the same time, the lower pressure plate applies pressure from the top. With the buffer compensation of the return spring, multi-dimensional tight limiting is achieved. Compared with the traditional single-direction clamping, this structure can effectively avoid displacement and skewing of the mold during assembly or testing, significantly improve clamping stability, and provide a guarantee for the accuracy of core assembly parameters such as cavity docking and guide post and guide sleeve mating.

[0024] The linear movement mechanism, consisting of the first linear slide, the first slider, the first conveying motor, and the first screw, enables the first screw to be precisely driven by the first conveying motor during the horizontal or vertical opening and closing test of the mold. This allows the mounting block to slide smoothly along the first linear slide, thereby achieving uniform and smooth relative movement between the moving mold and the fixed mold.

[0042] To enable those skilled in the art to more clearly understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0043] Example 1;

[0044] like Figures 1-9 As shown, this embodiment provides a high-efficiency clamping fixture for injection mold production, including a base 1. Both ends of the top of the base 1 are provided with mounting grooves 2. The lower flip plate 3 is rotatably mounted on one end of the mounting groove 2 near the center of the base 1 through a rotating shaft. The top of the two sets of lower flip plates 3 are horizontally slidably provided with mounting blocks 5. The top of the two sets of mounting blocks 5 near the center of the base 1 is rotatably mounted with an upper flip plate 7 through a rotating shaft.

[0045] The top of each upper flip plate 7 is provided with a clamping and fixing mechanism 9, which is used to fix the moving mold and the fixed mold of the injection mold respectively.

[0046] The base 1 is symmetrically provided with a rotating mechanism 4 on its side, which is used to drive the two sets of lower flip plates 3 to rotate around the rotating shaft respectively;

[0047] The top of each lower flap 3 is provided with a linear movement mechanism 6, which is used to drive the mounting block 5 to slide horizontally along the top of the lower flap 3;

[0048] Each mounting block 5 is equipped with a support mechanism 8 on its top, which is used to drive the upper flip plate 7 to rotate around the pivot.

[0049] Overall working principle: The moving mold and fixed mold of the injection mold are placed on the top of the two sets of upper flip plates 7 respectively. The clamping and fixing mechanism 9 is activated to perform bidirectional extrusion clamping on the protrusions of the mounting bases of the moving mold and fixed mold, thus completing the horizontal assembly and positioning of the mold. After assembly, if a horizontal opening and closing test is required, the upper flip plates 7 are driven to rotate around the pivot by the support mechanisms 8 at both ends of the base 1, rotating the two sets of upper flip plates 7 by 90 degrees. The linear movement mechanism 6 drives the mounting block 5 to slide horizontally along the top of the lower flip plate 3, causing the upper flip plates 7 and the fixed moving and fixed molds to move relative to each other. The system moves at a constant speed to achieve horizontal opening and closing tests. If it needs to switch to vertical opening and closing tests, the upper flip plate 7 is driven to rotate around the pivot by the support mechanism 8 at one end of the top of the base 1. At the same time, the lower flip plate 3 is driven to rotate around the pivot in the mounting groove 2 by the rotating mechanism 4. The postures of the moving mold and the fixed mold are adjusted to a vertically opposite state. Then, the mounting block 5 is driven to slide by the linear movement mechanism 6 on the lower flip plate 3 at the vertical position to complete the vertical opening and closing test. The whole process does not require disassembling the mold, realizing the integrated operation of "assembly-horizontal test-vertical test".

[0050] Example 2;

[0051] The solution in Example 1 will be further described below with reference to its specific working method.

[0052] In this embodiment, the rotating mechanism 4 includes a servo motor 401 and a reducer 402. The servo motor 401 is symmetrically mounted on the side of the base 1. The output end of the servo motor 401 is connected to the input end of the reducer 402. The output ends of the two sets of reducers 402 are respectively fixedly connected to the rotating shaft of the lower flip plate 3.

[0053] Local working principle: When the servo motor 401 is started, the power output by the servo motor 401 is reduced and increased in torque by the reducer 402, and then transmitted to the rotating shaft of the lower flip plate 3, which drives the lower flip plate 3 to rotate precisely around the rotating shaft in the mounting groove 2, thereby adjusting the overall placement angle of the lower flip plate 3, the top mounting block 5, and the upper flip plate 7 to meet the posture requirements of the opening and closing test.

[0054] In this embodiment, the linear movement mechanism 6 includes a first linear slide 601, a first slider 602, a first conveying motor 603, and a first screw 604. The first linear slide 601 is formed along the length of the lower flap 3 at the top of the lower flap 3. The first slider 602 is slidably embedded in the first linear slide 601 and its top is fixedly connected to the mounting block 5. The first conveying motor 603 is fixedly installed at one end of the lower flap 3. The first screw 604 is rotatably installed in the first linear slide 601 and threadedly connected to the first slider 602. One end of the first screw 604 is fixedly connected to the output end of the first conveying motor 603.

[0055] Partial working principle: When the first conveyor motor 603 is started, the first conveyor motor 603 drives the first screw 604 to rotate in the first linear slide groove 601. Since the first screw 604 is threadedly connected to the first slider 602 and the first slider 602 is slidably embedded in the first linear slide groove 601, the rotational motion of the first screw 604 is converted into the horizontal linear motion of the first slider 602, which in turn drives the mounting block 5, which is fixedly connected to the first slider 602, to slide smoothly along the top of the lower flip plate 3, thereby realizing the relative movement of the moving mold and the fixed mold.

[0056] In this embodiment, the support mechanism 8 includes a second linear slide 801, a second slider 802, a second conveying motor 803, a second screw 804, and a support rod 805. The second linear slide 801 is formed at the top of the mounting block 5 along the length direction of the mounting block 5. The second slider 802 is slidably embedded in the second linear slide 801. The second conveying motor 803 is fixedly installed at the end of the mounting block 5. The second screw 804 is rotatably installed in the second linear slide 801 and threadedly connected to the second slider 802. One end of the second screw 804 is fixedly connected to the output end of the second conveying motor 803. The support rod 805 is hinged between the top of the second slider 802 and the bottom of the upper flip plate 7.

[0057] Partial working principle: Start the second conveyor motor 803, which drives the second screw 804 to rotate in the second linear slide groove 801. The second screw 804 drives the second slider 802 to slide along the second linear slide groove 801. When the second slider 802 moves, it pushes the support rod 805 to rotate around the hinge point. The top of the support rod 805 pushes the upper flip plate 7, causing the upper flip plate 7 to rotate around the pivot at the top of the mounting block 5, thus completing the angle adjustment of the upper flip plate 7.

[0058] In this embodiment, a hidden groove 806 is provided at the bottom of the upper flip plate 7 along the length direction, the hinge point at the top of the support rod 805 is located inside the hidden groove 806, and the width of the hidden groove 806 is greater than the width of the support rod 805.

[0059] Local working principle: When no support is needed, the second slider 802 is moved in the reverse direction, and the support rod 805 is folded and stored in the hidden slot 806, which does not affect the horizontal placement of the upper flip plate 7.

[0060] In this embodiment, the clamping and fixing mechanism 9 includes a cross-shaped slide 901, a cylinder 902, a vertical plate 903, and a double-sided clamping assembly 904. The cross-shaped slide 901 is opened on the top of the upper flip plate 7. The cylinder 902 is fixedly installed at the end of the cross-shaped slide 901. The vertical plate 903 is slidably embedded in the cross-shaped slide 901 and fixedly connected to the output end of the cylinder 902. The double-sided clamping assembly 904 is disposed on the side of the vertical plate 903 near the mold and is used to perform bidirectional compression clamping on the side and top surface of the mounting edge protrusion of the moving mold or the fixed mold.

[0061] Local working principle: When the mold is fixed, the mold is first placed between multiple sets of vertical plates 903, and then the cylinder 902 is started. The cylinder 902 pushes the vertical plate 903 to slide along the cross-shaped slide groove 901 towards the mold. The vertical plate 903 drives the double-sided clamping assembly 904 to approach the edge protrusion of the mounting seat of the moving mold or fixed mold, and performs bidirectional compression clamping on the edge protrusion from the side and top.

[0062] In this embodiment, the double-sided clamping assembly 904 includes a horizontal plate 9041, a vertical groove 9042, a lower pressure plate 9043, a side pressure plate 9044, a sliding rod 9045, a horizontal groove 9046, a return spring 9047, and a connecting rod 9048. The horizontal plate 9041 is fixedly installed on the top of the vertical plate 903. The vertical groove 9042 is provided on the horizontal plate 9041, and the lower pressure plate 9043 is vertically slidably arranged inside the vertical groove 9042. The vertical plate 903 is close to the horizontal plate 9041. A transverse groove 9046 is evenly provided on one side along the length direction of 41. A sliding rod 9045 is horizontally slidably arranged inside the transverse groove 9046. A side pressure plate 9044 is fixed between the ends of multiple sets of sliding rods 9045. A connecting rod 9048 is hinged to the top of the side pressure plate 9044 and the side of the lower pressure plate 9043. A return spring 9047 is provided between the side pressure plate 9044 and the vertical plate 903. The return spring 9047 is sleeved on the outside of the sliding rod 9045.

[0063] Local working principle: During the movement of the vertical plate 903, the side pressure plate 9044 first contacts the edge of the mold. As the vertical plate 903 continues to advance, the slide rod 9045 slides along the horizontal groove 9046 towards the cylinder 902 and compresses the return spring 9047. At the same time, the side pressure plate 9044 pulls the lower pressure plate 9043 vertically downward along the vertical groove 9042 through the connecting rod 9048. Finally, the side pressure plate 9044 squeezes and limits the side of the mold, and the lower pressure plate 9043 presses and limits the top surface of the mold, forming a double-sided clamping and fixing effect. The return spring 9047 provides buffer compensation during the clamping process to ensure that the clamping force of the side pressure plate 9044 and the lower pressure plate 9043 is uniform. At the same time, when the cylinder 902 resets, it pushes the side pressure plate 9044 and the lower pressure plate 9043 back to the initial position, which facilitates the removal and placement of the mold.

[0064] In this embodiment, anti-slip textures are provided on the bottom end of the lower pressure plate 9043 and the side edge of the side pressure plate 9044, and the bottom end of the lower pressure plate 9043 and the side edge of the side pressure plate 9044 are both rectangular.

[0065] Local working principle: The anti-slip texture at the bottom of the lower pressure plate 9043 and the anti-slip texture on the side of the side pressure plate 9044 increases the friction with the mold mounting base, preventing the mold from sliding after clamping.

[0066] In this embodiment, the reducer 402 is a worm gear reducer, and the input end of the worm gear reducer is connected to the output end of the servo motor 401 through a coupling, and the output end of the worm gear reducer is connected to the key on the lower flip plate 3.

[0067] Local working principle: The worm gear reducer 402 is used to receive the output power of the servo motor 401 through the coupling. The speed reduction and torque increase are achieved through the meshing transmission of the worm wheel and worm. At the same time, the self-locking characteristic of the worm gear is used to fix the position of the rotating shaft of the lower flip plate 3 when the servo motor 401 stops working, so as to prevent the lower flip plate 3 from rotating due to external force and ensure the posture stability during the test.

[0068] In this embodiment, the bottom of the mounting block 5 is attached to the top of the lower flap 3, and the bottom of the mounting block 5 is coated with a wear-resistant coating.

[0069] Local working principle: The bottom of the mounting block 5 fits against the top of the lower flip plate 3 to ensure stability during sliding; the wear-resistant coating applied to the bottom reduces sliding friction loss between the mounting block 5 and the lower flip plate 3, extends the service life of the components, and ensures sliding accuracy after long-term use.

[0070] Example 3;

[0071] The solutions in Embodiments 1 and 2 will be further described below with reference to their specific working methods.

[0072] In use, first adjust both the lower flip plate 3 and the upper flip plate 7 to a horizontal state, and place the moving mold and the fixed mold in the designated positions of the two sets of upper flip plates 7 respectively; start the cylinder 902, which drives the double-sided clamping assembly 904 to move through the vertical plate 903, so that the side pressure plate 9044 and the lower pressure plate 9043 clamp the mold mounting seat from the side and the top surface respectively, and complete the assembly and fixation.

[0073] When conducting the horizontal opening and closing test, the second conveyor motors 803 at both ends of the base 1 are started. The second conveyor motors 803 drive the second screw 804 to rotate in the second linear slide 801. The second screw 804 drives the second slider 802 to slide along the second linear slide 801. When the second slider 802 moves, it pushes the support rod 805 to rotate around the hinge point. The top of the support rod 805 pushes the upper flip plate 7, so that the upper flip plate 7 rotates around the pivot of the top of the mounting block 5, thus completing the angle adjustment of the upper flip plate 7. Then, the first conveyor motor 603 drives the first screw 604 to rotate, which drives the first slider 602, the mounting block 5 and the upper flip plate 7 to move synchronously, realizing the horizontal opening and closing action of the moving mold and the fixed mold, and verifying the smoothness of the horizontal movement.

[0074] When switching to the vertical opening and closing test, the second conveyor motor 803 at one end of the base 1 is started to drive the second screw 804 to rotate. The second slider 802 pushes the support rod 805 to push the upper flip plate 7 to rotate to the vertical position. At the same time, the servo motor 401 drives the lower flip plate 3 to rotate through the reducer 402, so that the molds on the two sets of upper flip plates 7 are vertically opposite each other. The first conveyor motor 603 is started again to drive the mounting block 5 to slide, realizing the vertical opening and closing test of the moving mold and the fixed mold. The coordinated action of each mechanism throughout the process ensures the mold assembly accuracy and testing efficiency.

[0075] The above description is merely a further embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope disclosed in the present invention, based on the technical solution and concept of the present invention, shall fall within the scope of protection of the present invention.
