Technical Field

[0001] This utility model relates to the field of spliced ​​hot runner assembly technology, specifically to spliced ​​hot runner assembly tooling. Background Technology

[0002] Modular hot runner systems are hot runner systems composed of standardized modules. They can be flexibly adjusted according to the mold structure and are suitable for multi-cavity and complex molds. They are flexible, easy to maintain, and low in cost. Before use, modular hot runner systems need to be assembled with the help of assembly fixtures.

[0003] The hot runner assembly fixture with announcement number CN222538174U is based on a hot runner assembly fixture. A sliding adjustment chamber is provided inside the hot runner assembly fixture. An adjusting screw is movably mounted on the top side of the hot runner assembly fixture. An adjusting turntable is fixed to the top side of the adjusting screw. A sliding plate is rotatably connected to the top side of the adjusting screw, and the sliding plate is located away from the adjusting turntable. In use, the adjusting screw is rotated by the turntable to move the sliding plate to the desired position inside the hot runner assembly fixture. Then, the two fixed limiters are adjusted to a suitable distance. The hot runner mold body is placed on the fixed limiters, causing the fixed limiters to fix it in place, thus facilitating the assembly of the hot runner mold bodies on both sides and improving the accuracy of the hot runner mold body assembly.

[0004] The above-mentioned splicing hot runner assembly tooling still has problems. During the use of this assembly tooling, it can only assemble one side of the hot runner, and after fixing, the hot runner assembly position cannot be adjusted, resulting in low hot runner assembly efficiency. Therefore, a splicing hot runner assembly tooling is proposed. Utility Model Content

[0005] To address the shortcomings of existing technologies, commercially available assembly fixtures can only assemble one side of the hot runner during use, and once fixed, the hot runner assembly position cannot be adjusted, resulting in low assembly efficiency.

[0007] Preferably, the rotating mechanism includes a movable platform, a rotating platform rotatably mounted on the top side of the movable platform, positioning holes symmetrically opened on the top side of the movable platform, a sliding groove opened on the bottom side of the rotating platform, a locking block slidably mounted inside the sliding groove, a first spring fixedly connected between the locking block and one end of the inner side of the sliding groove, fixing plates symmetrically fixed at both ends of the top side of the rotating platform, a sliding rod slidably inserted inside the fixing plate, a clamping plate fixed at one end of the sliding rod, a second spring fixed between the clamping plate and the fixing plate, the second spring being fitted onto the sliding rod, and the locking block being snapped into the inner side of the positioning hole. The rotating platform has a rectangular structure. Through the structure of the rotating platform, the fixed spliced ​​hot runner can be flipped over to assemble the other side, thereby improving its assembly efficiency.

[0009] Preferably, the adjustment mechanism includes a rectangular groove, a limit rod fixed inside the rectangular groove, and a lead screw rotatably mounted inside the rectangular groove on the other side. A servo motor is fixed to the side of the processing table, and rectangular grooves are symmetrically opened on the top side of the processing table. The output end of the servo motor passes through the processing table and is fixedly connected to the lead screw. A movable table is connected to the limit rod through a sliding seat. A connecting seat is rotatably connected to the lead screw, and the top side of the connecting seat is fixedly connected to the movable table.

[0010] The advantages of this utility model are:

[0011] 1. This utility model, through the structural design of a splicing hot runner assembly fixture, uses a rotating mechanism to push a rotating table to rotate around the center of a moving table. When the locking block moves to the top side of the positioning hole, the first spring pushes the locking block to engage with the inside of the positioning hole, limiting the rotation table. At this point, the other side of the splicing hot runner can be assembled, improving the assembly efficiency of the splicing hot runner and solving the problem of low assembly efficiency of existing assembly fixtures.

[0012] 2. This utility model utilizes a modular hot runner assembly fixture design. By setting up a fixing mechanism, a second spring pushes the two side clamps into contact with the modular hot runner.

[0020] 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 scope of protection of the present utility model.

[0021] Please see Figure 1-4 As shown, the modular hot runner assembly fixture includes a processing table 1; a rotating mechanism is provided on the top side of the processing table 1, a fixing mechanism is provided on the top side of the rotating mechanism, an adjusting mechanism is provided on the inner side of the processing table 1, and a movable table 5 is symmetrically slidably installed on the top side of the processing table 1.

[0022] Please see Figure 2As shown, the rotating mechanism includes a movable platform 5, a rotating platform 6 rotatably mounted on the top side of the movable platform 5, positioning holes 10 symmetrically opened on the top side of the movable platform 5, a sliding groove 7 opened on the bottom side of the rotating platform 6, a locking block 8 slidably mounted inside the sliding groove 7, a first spring 9 fixedly connected between the locking block 8 and one end of the inner side of the sliding groove 7, fixing plates 11 symmetrically fixed at both ends of the top side of the rotating platform 6, a sliding rod 12 slidably inserted inside the fixing plate 11, a clamping plate 13 fixed at one end of the sliding rod 12, a second spring 14 fixed between the clamping plate 13 and the fixing plate 11, the second spring 14 being fitted onto the sliding rod 12, and the locking block 8 being fastened to... Inside the positioning hole 10, the rotary table 6 has a rectangular structure. During operation, when the existing assembly fixture requires disassembling the workpiece before the assembly surface can be changed, resulting in low assembly efficiency of the spliced ​​hot runner, the structure of the rotating mechanism is used to fix the spliced ​​hot runner to the top side of the rotary table 6. At this time, the rotary table 6 can be pushed to rotate around the center of the moving table 5. After the rotary table 6 drives the spliced ​​hot runner to flip, the locking block 8 moves to the top side of the positioning hole 10. The first spring 9 pushes the locking block 8 to be fastened inside the positioning hole 10, limiting the rotation table 6. At this time, the other side of the spliced ​​hot runner can be assembled, improving the assembly efficiency of the spliced ​​hot runner.

[0023] Please see Figure 3 The fixing mechanism shown includes a limiting seat 15, with a trapezoidal plate 16 slidably inserted inside the limiting seat 15. The surface of the rotating table 6 is evenly provided with fixing grooves 17. The limiting seat 15 is symmetrically fixed to the back of the clamping plate 13. The trapezoidal plates 16 on both sides are fixedly connected by straight rods, and the trapezoidal plates 16 are fastened to the inside of the fixing grooves 17. During operation, when encountering the problem of cumbersome operation when disassembling and assembling workpieces using existing assembly tools, the structure of the fixing mechanism allows for easier assembly. The hot runner is placed inside the clamping plate 13. The second spring 14 pushes the clamping plates 13 on both sides to slide inward until the clamping plates 13 contact the hot runner. At this time, the trapezoidal plate 16 slides downward inside the limiting seat 15 and is fastened inside the fixing groove 17 to fix the position of the clamping plate 13 and prevent the hot runner from falling off. When disassembly is required, the trapezoidal plate 16 can be pulled up to raise it. At this time, the clamping plate 13 can be retracted to remove the assembled hot runner, which is more convenient for operators to use.

[0024] Please see Figure 4As shown, the adjustment mechanism includes a rectangular groove 2, with a limit rod 4 fixed inside the rectangular groove 2. A lead screw 3 is rotatably installed inside the rectangular groove 2 on the other side. A servo motor 18 is fixed to the side of the processing table 1. Rectangular grooves 2 are symmetrically opened on the top side of the processing table 1. The output end of the servo motor 18 passes through the processing table 1 and is fixedly connected to the lead screw 3. A moving table 5 is connected to the limit rod 4 through a sliding seat 19. A connecting seat 20 is rotatably connected to the lead screw 3. The top side of the connecting seat 20 is fixedly connected to the moving table 5. During operation, when encountering the problem of easy tipping when using existing assembly fixtures, the structure of the adjustment mechanism controls the servo motor 18 to drive the lead screw 3 at the output end to rotate. At this time, with the cooperation of the connecting seat 20, the moving tables 5 on both sides move along the limit rod 4 in opposite directions, thereby facilitating the operator to move the workpiece to the assembly position for subsequent assembly processing.

[0025] Please see Figure 5 As shown, a rubber pad 21 is fixed to the clamping surface of the clamping plate 13. During operation, when encountering the problem of easy detachment during the clamping process of the spliced ​​hot runner, the structure of the rubber pad 21 can increase the friction between the clamping plate 13 and the clamping surface of the spliced ​​hot runner, while also preventing the spliced ​​hot runner from deforming due to excessive force.

[0026] Working Principle: The modular hot runner system is composed of standardized modules. It can be flexibly adjusted according to the mold structure, making it suitable for multi-cavity and complex molds. It offers advantages such as flexibility, ease of maintenance, and low cost. Before use, the modular hot runner system requires assembly with the aid of assembly fixtures. Existing assembly fixtures can only assemble one side of the hot runner, and once fixed, the assembly position cannot be adjusted, resulting in low assembly efficiency. To solve this problem, a rotating and fixing mechanism is used. The modular hot runner is placed inside the clamping plate 13. The second spring 14 pushes the clamping plates 13 on both sides to slide inward until they contact the modular hot runner. At this point, the trapezoidal plate 16 slides downward inside the limiting seat 15 and is fastened inside the fixing groove 17, fixing the position of the clamping plate 13 and preventing the modular hot runner from falling off. The servo motor 18 is controlled to drive the output screw 3 to rotate. With the cooperation of the connecting seat 20, the two moving platforms 5 are driven to move inward along the limiting rod 4. When the two spliced ​​hot runners are moved to the required position, the fixed spliced ​​hot runners can be assembled. When the assembly surface needs to be replaced after assembly, the servo motor 18 is controlled to separate the two moving platforms 5. At this time, the rotary table 6 can be pushed to rotate around the center of the moving platform 5. After the rotary table 6 drives the spliced ​​hot runners to flip, the locking block 8 moves to the top side of the positioning hole 10. The first spring 9 pushes the locking block 8 to be fastened to the inside of the positioning hole 10, limiting the rotary table 6. At this time, the other side of the spliced ​​hot runners can be assembled, improving the assembly efficiency of the spliced ​​hot runners. After the assembly is completed, the trapezoidal plate 16 is pulled to rise. At this time, the clamping plate 13 can be retracted to remove the assembled spliced ​​hot runners so that the next spliced ​​hot runner can be assembled. This solves the problem of low assembly efficiency of the existing assembly tooling.
