Description

TECHNICAL FIELD

[0001] The application relates to a special clamp for injection mold production, in particular to a high-efficiency special clamp for injection mold production, and belongs to the technical field of clamps. BACKGROUND

[0002] In the injection mold production process, the precise assembly of the mold plate and the mold opening performance test are the key links to ensure the molding precision of the mold and prolong the service life. On the one hand, the special clamp is needed to realize the stable positioning of the movable mold and the fixed mold during the mold assembly stage, so as to avoid displacement and deflection during the assembly process, ensure that the core assembly parameters such as cavity butt joint, guide column guide sleeve cooperation meet the design requirements; on the other hand, after the assembly is completed, the horizontal mold opening test and the vertical mold opening test are carried out in turn to verify the smoothness of the mold in different opening directions, the guiding accuracy and the stress balance, and to check potential problems such as interference, jamming or abnormal gap.

[0003] However, the existing clamps for injection mold production generally have the defects of fixed shape and single function: most of the clamps can only realize the clamping and fixing in a single direction (horizontal or vertical), cannot simultaneously limit the movable mold and the fixed mold, and need to repeatedly disassemble and assemble the clamp and adjust the mold placement posture during the test process; and the clamps lack flexible position adjustment function, cannot adapt to the clamping needs of molds of different specifications, and cannot quickly fine-tune the relative position of the movable mold and the fixed mold according to the test scene, which not only increases the complexity of the test operation, but also prolongs the preparation time of the mold opening test and reduces the efficiency, seriously affecting the overall rhythm and delivery cycle of the mold production.

[0004] Therefore, a high-efficiency special clamp for injection mold production is designed to optimize the above problems. SUMMARY

[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.

[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 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 side of the base 1 is symmetrically provided with a rotating mechanism 4 for driving two groups of the lower turning plates 3 to rotate around the rotating shafts, respectively.

[0047] The top of each lower turning plate 3 is provided with a linear moving mechanism 6 for driving the mounting block 5 to slide horizontally along the top of the lower turning plate 3.

[0048] The top of each mounting block 5 is provided with a supporting mechanism 8 for driving the upper turning plate 7 to rotate around the rotating shaft.

[0049] The overall working principle is as follows: the movable mold and the fixed mold of the injection mold are respectively placed on the top of the two groups of upper turning plates 7, the clamping and fixing mechanism 9 is started to clamp and fix the edge protrusions of the mounting seats of the movable mold and the fixed mold in a bidirectional extrusion manner, and the mold is horizontally assembled and positioned; after the assembly is completed, if horizontal opening and closing test is needed to be carried out, the upper turning plates 7 are driven by the supporting mechanisms 8 at both ends of the base 1 to rotate around the rotating shafts by ninety degrees, the mounting blocks 5 are driven by the linear moving mechanisms 6 to slide horizontally along the top of the lower turning plates 3, and the upper turning plates 7 and the fixed movable mold and fixed mold are driven to move at a uniform speed, so that the horizontal opening and closing test is realized; if it is needed to switch to vertical opening and closing test, the upper turning plates 7 are driven by the supporting mechanisms 8 at one end of the top of the base 1 to rotate around the rotating shafts, and the lower turning plates 3 are driven by the rotating mechanisms 4 to rotate around the rotating shafts in the mounting groove 2 at the same time, so that the posture of the movable mold and the fixed mold is adjusted to a vertical relative state, and then the mounting blocks 5 are driven by the linear moving mechanisms 6 on the lower turning plates 3 at the vertical position to slide, so that the vertical opening and closing test is completed; the whole process does not need to disassemble the mold, and the integrated operation of “assembly-horizontal test-vertical test” is realized.

[0050] Embodiment 2;

[0051] The scheme in embodiment 1 will be further introduced in combination with a specific working mode, and details are described as follows:

[0052] In this embodiment, the rotating mechanism 4 includes a servo motor 401 and a speed reducer 402, the servo motor 401 is symmetrically installed on the side of the base 1, the output end of the servo motor 401 is in transmission connection with the input end of the speed reducer 402, and the output ends of the two groups of speed reducers 402 are fixedly connected with the rotating shafts of the lower turning plates 3, respectively.

[0053] Partial working principle: the servo motor 401 is started, the power output by the servo motor 401 is transmitted to the rotating shaft of the lower turning plate 3 after being reduced and increased in torque by the speed reducer 402, the lower turning plate 3 is driven to rotate accurately around the rotating shaft in the mounting groove 2, and then the overall placement angle of the lower turning plate 3, the mounting block 5 and the upper turning plate 7 is adjusted, so as to adapt to the posture requirement of the opening and closing test.

[0054] In the embodiment, the linear moving mechanism 6 comprises a first linear sliding groove 601, a first sliding block 602, a first conveying motor 603 and a first screw rod 604. The first linear sliding groove 601 is arranged on the top of the lower flap 3 along the length direction of the lower flap 3. The first sliding block 602 is slidingly embedded in the first linear sliding groove 601 and is fixedly connected with the mounting block 5 at the top. The first conveying motor 603 is fixedly installed at one end of the lower flap 3. The first screw rod 604 is rotatably installed in the first linear sliding groove 601 and is threadedly connected with the first sliding block 602. One end of the first screw rod 604 is fixedly connected with the output end of the first conveying motor 603.

[0055] The local working principle is as follows: the first conveying motor 603 is started to drive the first screw rod 604 to rotate in the first linear sliding groove 601. Since the first screw rod 604 is threadedly connected with the first sliding block 602 and the first sliding block 602 is slidingly embedded in the first linear sliding groove 601, the rotational movement of the first screw rod 604 is converted into the horizontal linear movement of the first sliding block 602, thereby driving the mounting block 5 fixedly connected with the first sliding block 602 to stably slide along the top of the lower flap 3, so as to realize the relative movement of the movable mold and the fixed mold.

[0056] In the embodiment, the supporting mechanism 8 comprises a second linear sliding groove 801, a second sliding block 802, a second conveying motor 803, a second screw rod 804 and a supporting rod 805. The second linear sliding groove 801 is arranged on the top of the mounting block 5 along the length direction of the mounting block 5. The second sliding block 802 is slidingly embedded in the second linear sliding groove 801. The second conveying motor 803 is fixedly installed at the end of the mounting block 5. The second screw rod 804 is rotatably installed in the second linear sliding groove 801 and is threadedly connected with the second sliding block 802. One end of the second screw rod 804 is fixedly connected with the output end of the second conveying motor 803. The supporting rod 805 is hingedly installed between the top of the second sliding block 802 and the bottom of the upper flap 7.

[0057] The local working principle is as follows: the second conveying motor 803 is started to drive the second screw rod 804 to rotate in the second linear sliding groove 801. The second screw rod 804 drives the second sliding block 802 to slide along the second linear sliding groove 801. When the second sliding block 802 moves, it pushes the supporting rod 805 to rotate around the hinged point. The top of the supporting rod 805 pushes the upper flap 7, so that the upper flap 7 rotates around the rotating shaft at the top of the mounting block 5, thereby completing the angle adjustment of the upper flap 7.

[0058] In the embodiment, the bottom of the upper flap 7 is provided with a hidden groove 806 along the length direction. The hinged point at the top end of the supporting rod 805 is located in the hidden groove 806, and the width of the hidden groove 806 is greater than the width of the supporting rod 805.

[0059] Local working principle: when no support is needed, the second slider 802 is driven to move reversely, the support rod 805 is folded and stored in the hidden groove 806, which does not affect the horizontal placement of the upper turnover plate 7.

[0060] In the embodiment, the clamping and fixing mechanism 9 comprises a cross-shaped sliding groove 901, a cylinder 902, a vertical plate 903 and a double-sided clamping assembly 904. The cross-shaped sliding groove 901 is arranged on the top of the upper turnover plate 7. The cylinder 902 is fixedly installed at the end of the cross-shaped sliding groove 901. The vertical plate 903 is slidingly embedded in the cross-shaped sliding groove 901 and is fixedly connected with the output end of the cylinder 902. The double-sided clamping assembly 904 is arranged on the side of the vertical plate 903 close to the mold, and is used for bidirectional extrusion clamping of the edge protrusion of the mounting seat of the movable mold or the fixed mold from the side and the top.

[0061] Local working principle: when the mold is fixed, the mold is first placed between the multiple vertical plates 903, and then the cylinder 902 is started. The cylinder 902 drives the vertical plate 903 to slide along the cross-shaped sliding 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 movable mold or the fixed mold, and clamps the edge protrusion from the side and the top.

[0062] In the embodiment, the double-sided clamping assembly 904 comprises a horizontal plate 9041, a vertical groove 9042, a pressing plate 9043, a side pressing plate 9044, a sliding rod 9045, a horizontal groove 9046, a reset 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 arranged on the horizontal plate 9041. The pressing plate 9043 is vertically slidingly arranged in the vertical groove 9042. The horizontal groove 9046 is evenly arranged on the side of the vertical plate 903 close to the horizontal plate 9041 along the length direction. The sliding rod 9045 is horizontally slidingly arranged in the horizontal groove 9046. The side pressing plate 9044 is fixedly arranged between the ends of the multiple sliding rods 9045. The connecting rod 9048 is hingedly installed on the top of the side pressing plate 9044 and the side of the pressing plate 9043. The reset spring 9047 is arranged between the side pressing plate 9044 and the vertical plate 903, and 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 mold edge, and as the vertical plate 903 continues to advance, the slide rod 9045 slides along the horizontal groove 9046 towards the air cylinder 902 and compresses the return spring 9047, at the same time, the side pressure plate 9044 pulls the lower pressing plate 9043 through the connecting rod 9048 to move vertically downward along the vertical groove 9042, finally realizing the extrusion and limiting of the side pressure plate 9044 on the side edge of the mold, and the pressing and limiting of the lower pressing plate 9043 on the top surface of the mold, forming a double clamping and fixing effect, the return spring 9047 provides buffer compensation during clamping, ensuring that the clamping force of the side pressure plate 9044 and the lower pressing plate 9043 is uniform, and at the same time, when the air cylinder 902 resets, it pushes the side pressure plate 9044 and the lower pressing plate 9043 back to the initial position, facilitating the taking and placing of the mold.

[0064] In this embodiment, the bottom end of the lower pressing plate 9043 and the side edge of the side pressure plate 9044 are both provided with anti-skid lines, and the shape of the bottom end of the lower pressing plate 9043 and the side edge of the side pressure plate 9044 is rectangular.

[0065] Local working principle: the anti-skid lines on the bottom end of the lower pressing plate 9043 and the side edge of the side pressure plate 9044 increase the friction with the mold mounting seat, avoiding sliding displacement of the mold after clamping.

[0066] In this embodiment, the speed reducer 402 is a worm gear reducer, and the input end of the worm gear reducer is connected with the output end of the servo motor 401 through a shaft coupling, and the output end of the worm gear reducer is keyed connected with the rotating shaft on the lower turning plate 3.

[0067] Local working principle: the worm gear reducer 402 adopted receives the output power of the servo motor 401 through the shaft coupling, realizes speed reduction and torque increase through the meshing transmission of the worm gear and the worm, and at the same time, utilizes the self-locking characteristic of the worm gear and the worm to fix the position of the rotating shaft of the lower turning plate 3 when the servo motor 401 stops working, avoiding the rotation of the lower turning plate 3 due to external force, and ensuring the posture stability during testing.

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

[0069] Local working principle: the bottom of the mounting block 5 is attached to the top of the lower turning plate 3, ensuring the stability during sliding; the wear-resistant coating coated on the bottom end reduces the sliding friction loss between the mounting block 5 and the lower turning plate 3, prolongs the service life of the components, and at the same time, ensures the sliding accuracy after long-term use.

[0073] When the horizontal opening and closing test is carried out, the second conveying motor 803 at both ends of the base 1 is started, the second conveying motor 803 drives the second screw 804 to rotate in the second linear sliding groove 801, the second screw 804 drives the second sliding block 802 to slide along the second linear sliding groove 801, the second sliding block 802 moves to push the supporting rod 805 to rotate around the hinge point, the top of the supporting rod 805 pushes the upper turning plate 7, so that the upper turning plate 7 rotates around the rotating shaft at the top of the mounting block 5, the angle adjustment of the upper turning plate 7 is completed, then the first conveying motor 603 drives the first screw 604 to rotate, drives the first sliding block 602, the mounting block 5 and the upper turning plate 7 to move synchronously, realizes the horizontal opening and closing action of the movable mold and the fixed mold, and verifies the smoothness of the horizontal movement;

[0074] When the vertical opening and closing test is switched, the second conveying motor 803 at one end of the base 1 is started to drive the second screw 804 to rotate, the second sliding block 802 pushes the supporting rod 805 to push the upper turning plate 7 to rotate to the vertical state, at the same time, the servo motor 401 drives the lower turning plate 3 to rotate through the reducer 402, so that the molds on the two groups of upper turning plates 7 are vertically and oppositely distributed; the first conveying motor 603 is started again to drive the mounting block 5 to slide, realizes the vertical opening and closing test of the movable mold and the fixed mold, and the whole process is realized through the cooperative action of each mechanism, guarantees the mold assembly precision and test efficiency.
