Description

Technical Field

[0001] The utility model belongs to the technical field of injection molding correction, in particular to an injection molding correction device. Background Art

[0002] Injection molded parts refer to various injection molded products produced by injection molding machines, including various packages, parts, etc. Injection molded parts are prone to thermal expansion and contraction deformation after injection molding. Injection molded parts will produce certain shrinkage deformation during the cooling process after injection molding is completed and taken out of the mold. This shrinkage deformation will affect the quality of the injection molded products, making them defective or defective products, resulting in a waste of resources. In order to reduce the shrinkage deformation during the cooling process of injection molded parts and affect the quality of injection molded parts, an injection molded parts correction device is needed to correct them.

[0003] Publication No. "CN220482566U" discloses "a device for correcting injection molded parts", which is used in conjunction with a rotating motor, a turntable, a rotating rod, a connecting rod, a rotating shaft, a fixed block, a correction plate, a mounting rod, a clamping rod, a fixed plate, a pull rod, a tension spring, a vertical plate, a slide rail, a first slider and a limit rod. By starting the rotating motor to drive the rotating rod and the connecting rod to rotate, the fixed block performs horizontal reciprocating motion under the action of the limit rod, the first slider and the slide rail, thereby achieving an automated correction effect. When different correction plates need to be replaced, the clamping rod is disengaged from the mounting rod by pulling the two pull rods under the action of the tension spring, and different correction plates can be replaced to correct different injection molded parts, thereby improving practicality.

[0004] The above technical solution still has the following disadvantages during the specific implementation process:

[0005] Since the length of the connecting rod is fixed, and the height of the correction plate when the connecting rod drives it to move downward to the lowest point is fixed, when the plate-like injection molded part is thicker, as the connecting rod squeezes the correction plate downward, it is easy to cause the injection molded part to be over-squeezed and deformed. When the plate-like injection molded part is thinner, the correction plate cannot contact the injection molded part when it moves down to the lowest point, and thus the correction treatment of the injection molded part cannot be achieved, making the device unable to adapt to the correction treatment of injection molded parts of different thicknesses. When replacing the correction plate, it is necessary to pull the hand pull rods on both sides at the same time, and it cannot be operated with one hand, which makes the replacement of the correction plate more inconvenient and the use effect is not good.

[0006] In view of the above problems, we propose an injection molded parts correction device. Utility Model Content

DETAILED DESCRIPTION

[0024] This specific embodiment is an injection molded part correction device, such as Figure 1-Figure 6 As shown, the injection molded part correction device includes a processing table 1 and a correction plate 2. A fixing frame 3 is fixed on the processing table 1. A through groove is provided on the fixing frame 3. A disc 5 is arranged in the through groove. A rotating rod is fixed on one side of the surface of the disc 5. A connecting arm 6 is installed on the rotating rod. A fixing plate 7 is hinged at the lower end of the connecting arm 6. A movable plate 8 is arranged on the lower side of the fixing plate 7. A plurality of piston rods 9 are movably arranged on the fixing plate 7. The lower end of the piston rod 9 is fixedly connected to the movable plate 8, and a plurality of first springs 10 are connected between the fixing plate 7 and the movable plate 8. A fixing tube 12 is fixed to the bottom of the movable plate 8. A sleeve 11 is fixed to the top of the correction plate 2 and cooperates with the fixing tube 12. A movable groove 13 is provided on the movable plate 8 and is connected to the inner cavity of the fixing tube 12. A locking piece is arranged inside the movable groove 13 and cooperates with the sleeve 11.

[0025] Through the joint action of the disc 5, the rotating rod and the connecting arm 6, combined with the mutual cooperation of the fixed plate 7, the piston rod 9 and the movable plate 8, the correction plate 2 is driven to reciprocate up and down, thereby realizing the correction operation of the injection molded parts. Under the elastic action of the first spring 10, the movable range of the correction plate 2 is effectively increased to adapt to the correction of injection molded parts of different thicknesses.

[0026] The locking member includes a support rod 14, a paddle plate 15, a second spring 16, a positioning hole 17 and a positioning block 18. The support rod 14 is fixed to the lower side of the inner cavity of the fixed tube 12. The two paddle plates 15 are slidably sleeved on the support rod 14. The two ends of the second spring 16 are respectively connected to the paddle plates 15 on both sides. A plurality of positioning holes 17 are penetrated on the surface of the sleeve 11, and a plurality of through holes are penetrated on the surface of the fixed tube 12. A plurality of positioning blocks 18 are relatively fixed on the sides of the two paddle plates 15 that are away from each other, and the positioning blocks 18 cooperate with the through holes and the positioning holes 17.

[0027] Through the elastic action of the second spring 16, combined with the sliding cooperation between the paddle plate 15 and the support rod 14, it is convenient to squeeze the two paddle plates 15 to the two sides respectively, thereby driving the positioning block 18 to pass through the through hole and insert it into the corresponding positioning hole 17, so that the sleeve 11 and the fixing tube 12 are fixedly connected together, thereby realizing the installation and fixation of the correction plate 2. When the correction plate 2 is subsequently disassembled and replaced, it is only necessary to squeeze the paddle plates 15 on both sides toward the center to drive the positioning block 18 to disengage from the corresponding positioning hole 17, thereby facilitating the rapid disassembly and fixation of the correction plate 2, and solving the problem in the prior art that when replacing the correction plate 2, it is necessary to pull the hand pull rods on both sides at the same time, and it is impossible to operate with one hand, making the replacement of the correction plate 2 more inconvenient.

[0028] A U-shaped plate 4 is provided at the center of the upper surface of the processing table 1, and a cylinder 19 is installed on one side of the fixed frame 3. The telescopic end of the cylinder 19 passes through the fixed frame 3 and is connected to a push plate 20. The push plate 20 cooperates with the inner cavity of the U-shaped plate 4. An avoidance groove 21 is penetrated on the side of the surface of the fixed frame 3 away from the cylinder 19, and a guide plate 22 with an inclined top is provided on the end of the U-shaped plate 4 close to the avoidance groove 21. A collecting groove 23 is provided on one side of the processing table 1, which cooperates with the guide plate 22. The U-shaped plate 4 facilitates the placement of the injection molded parts to be corrected. Under the action of the cylinder 19, combined with the push plate 20, it is convenient to push the injection molded parts after correction in the direction of the avoidance groove 21. Combined with the inclined surface at the top of the guide plate 22, it is convenient for the injection molded parts to slide to the right to the collecting groove 23 for unified collection.

[0029] A mounting plate is fixed on the top of the fixing frame 3 , a servo motor 24 is mounted on one side of the mounting plate, and an output shaft of the servo motor 24 is connected to the disc 5 .

[0030] A guide groove 27 is provided on the inner side of the fixed frame 3 near the cylinder 19, and a guide rod 26 is arranged inside the guide groove 27. A guide plate 25 is slidably sleeved on the guide rod 26. The end of the guide plate 25 away from the guide groove 27 is fixedly connected to the fixed plate 7. Through the sliding cooperation between the guide plate 25 and the guide rod 26, the fixed plate 7 is effectively limited and guided, thereby ensuring the stability of the up and down reciprocating movement of the correction plate 2.

[0031] The first spring 10 is sleeved on the outside of the piston rod 9 , and the second spring 16 is sleeved on the outside of the support rod 14 .

[0032] Example:

[0033] When in use, the plate-shaped injection molded part to be corrected is first placed on the inner side of the U-shaped plate 4, and the servo motor 24 is started at the same time. The servo motor 24 drives the disc 5 to rotate, and under the cooperation of the rotating rod and the connecting arm 6, combined with the sliding cooperation of the guide plate 25 and the guide rod 26, the fixed plate 7 is driven to reciprocate up and down stably, and then the correction plate 2 is driven to reciprocate up and down, which facilitates the correction of the injection molded part;

[0034] When the injection molded part is thicker, when the correction plate 2 moves down to contact the injection molded part, under the elastic action of the first spring 10, combined with the active cooperation of the piston rod 9 and the fixed plate 7, it is convenient for the connecting arm 6 to continue to squeeze the fixed plate 7 downward, so that the first spring 10 is compressed, thereby facilitating the rotation of the disc 5, and the connecting arm 6 drives the fixed plate 7 to move downward, so as to facilitate the correction of the thicker injection molded part, and avoid the injection molded part being too thick, when the correction plate 2 contacts the injection molded part, the rotating rod has not rotated to the lowest point, and under the mutual cooperation of the disc 5 and the connecting arm 6, the correction plate 2 continues to move downward, so that the injection molded part is over-extruded and deformed;

[0035] When the injection molded part is thin, when the connecting arm 6 drives the fixing plate 7 to move down to the lowest position, under the elastic action of the first spring 10, combined with the active cooperation of the piston rod 9 and the fixing plate 7, the correction plate 2 is pressed downward to contact with the injection molded part, and the thinner injection molded part is corrected to avoid the injection molded part being too thin and the correction plate 2 being unable to contact with the injection molded part when it moves down to the lowest position, resulting in the inability to correct the thinner injection molded part;

[0036] When disassembling and replacing the correction plate 2, hold the upper ends of the two shift plates 15 with one hand and squeeze the two shift plates 15 toward the center to compress the second spring 16, drive the positioning block 18 to disengage from the corresponding positioning hole 17, so that the sleeve 11 and the fixing tube 12 are quickly separated, and the correction plate 2 can be quickly replaced.

[0037] Compared with the prior art, the utility model, under the elastic action of the first spring 10, combines the movable cooperation of the piston rod 9 and the fixed plate 7, effectively increases the movable range of the correction plate 2, adapts to the correction treatment of injection molded parts of different thicknesses, and solves the problem in the prior art that the length of the connecting rod is fixed, and then the height of the correction plate 2 driven by the connecting rod to move downward to the lowest point is fixed. When the plate-like injection molded part is thicker, as the connecting rod squeezes the correction plate 2 downward, it is easy to cause the injection molded part to be over-extruded and deformed. When the plate-like injection molded part is thinner, when the correction plate 2 moves down to the lowest point, it cannot contact the injection molded part, and then the correction treatment of the injection molded part cannot be achieved, making it impossible for the device to perform correction treatment on injection molded parts of different thicknesses.

[0038] At the same time, under the joint action of the paddle plate 15, the support rod 14, the second spring 16 and the positioning block 18, it is easy to operate with one hand, and the paddle plates 15 on both sides are squeezed to facilitate the rapid disassembly and replacement of the correction plate 2, which solves the problem in the prior art that when replacing the correction plate 2, it is necessary to pull the hand pull rods on both sides at the same time, and it is impossible to operate with one hand, making the replacement of the correction plate 2 inconvenient.

[0039] It should be further explained that the installation structure, connection method or setting method of each component in the utility model are all common mechanical methods, and they can be implemented as long as they can achieve their beneficial effects. At the same time, the servo motor 24 and the cylinder 19 in the utility model are purchased on the market, and technical personnel in this field can install and use them according to requirements.
