Description
Technical Field
[0001] This utility model relates to the field of injection molding processing technology, and in particular to a slitting device for injection molded parts. Background Technology
[0002] In order to improve production efficiency, some injection molded products adopt multi-cavity molds or continuous injection molding methods when designing molds. For example, some plastic toys may be injection molded into multiple connected small toys at the same time in one mold. These connected toys can be easily separated into independent individuals by cutting equipment, which facilitates subsequent packaging, sales and other processes.
[0003] Existing injection molding slitting equipment requires manual pushing of the injection molded parts to the slitting position under the slitting machine. This method makes it difficult to ensure that each injection molded part can be accurately placed in the designated position of the slitting equipment. Positioning errors may lead to inaccurate slitting positions, affecting the slitting quality of the injection molded parts and causing problems such as dimensional deviations and uneven cuts. In addition, the speed of manual feeding is difficult to keep up with the running speed of the slitting equipment, which can easily cause the equipment to wait for feeding, resulting in low overall production efficiency. Utility Model Content
[0004] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide a feeding plate that moves the injection molded part from right to left to the cutting position, accurately placing it below the injection molded part cutting machine. This solves the problem that it is difficult to ensure that each injection molded part can be accurately placed in the designated position of the cutting equipment when manually pushing the injection molded part to the cutting position below the cutting machine.
[0005] To solve the problems of the existing technology, the technical solution of this utility model is as follows: A slitting device for injection molded parts includes a slitting table, an injection molded part slitting machine is movably connected to the outer wall of the slitting table, a mounting plate is fixedly connected to the outer wall of the slitting table, a motor is fixedly connected to the top of the mounting plate, a support frame is fixedly connected to the top of the motor output shaft, a middle circular block, an inner circular ring, and an outer circular ring are fixedly connected to the top of the support frame, a notch is opened on the inner circular ring, a limit plate is fixedly connected to the outer wall of the slitting table, a limit groove is opened on the outer wall of the limit plate, an L-shaped rod is slidably connected to the inner wall of the limit groove, and one end of the L-shaped rod is fixed. The device is connected to a movable bolt, the outer wall of which is slidably connected to the middle block, inner ring, and outer ring. The position of the L-shaped rod can be changed by changing the position of the movable bolt on the middle block, inner ring, and outer ring. When the movable bolt is located in the groove between the middle block and the inner ring, the L-shaped rod is located on the far right of the limiting groove. When the movable bolt is located in the groove between the inner ring and the outer ring, the L-shaped rod is located on the far left of the limiting groove. The L-shaped rod drives the feeding plate to move through the telescopic mechanism. The feeding plate moves from right to left to push the injection molded part to be fed and cut. The telescopic mechanism is used to prevent the feeding plate from contacting the injection molded part when it returns from left to right.
[0006] Preferably, a rotating shaft is rotatably connected to the top of the middle circular block, and an inner guide plate is fixedly connected to the top of the rotating shaft. A first torsion spring is sleeved on the outer wall of the rotating shaft, and the two ends of the first torsion spring are fixedly connected to the opposite sides of the middle circular block and the inner guide plate, respectively. When the inner guide plate contacts the moving bolt, the moving bolt moves along the inclined edge of the inner guide plate from the groove between the middle circular block and the inner ring to the groove between the inner ring and the outer ring. This process causes the feeding plate to move from right to left. A rotating shaft is rotatably connected to the top of the outer ring, and an outer guide plate is fixedly connected to the top of the rotating shaft. A second torsion spring is sleeved on the outer wall of the rotating shaft, and the two ends of the second torsion spring are fixedly connected to the opposite sides of the outer ring and the outer guide plate, respectively. When the outer guide plate contacts the moving bolt, the moving bolt moves along the inclined edge of the outer guide plate from the groove between the inner ring and the outer ring to the groove between the middle circular block and the inner ring, this process causes the feeding plate to move from left to right.
[0007] Preferably, an inner stop bolt is fixedly connected to the top of the middle circular block, which is used to fix the initial position of the inner guide plate, and an outer stop bolt is fixedly connected to the top of the outer circular ring, which is used to fix the initial position of the outer guide plate.
[0008] Preferably, the L-shaped rod and the limiting groove are connected by a sliding block, so that the L-shaped rod can only slide left and right in the limiting groove and cannot move back and forth. That is, the front and back position of the moving bolt will not change, but it can only move left and right.
[0009] Preferably, the telescopic mechanism includes a telescopic rod, the outer wall of which is slidably connected to one end of an L-shaped rod, a telescopic bolt slidably connected to the bottom of the telescopic rod, a compression plate fixedly connected to the outer wall of the telescopic bolt, a spring sleeved on the outer wall of the telescopic bolt, the top of the spring slidably connected to the bottom of the L-shaped rod, and the bottom of the spring fixedly connected to the top of the compression plate, a telescopic groove is provided at the bottom of the L-shaped rod, the inner wall of the telescopic groove is slidably connected to the outer wall of the telescopic bolt, one end of the telescopic rod is fixedly connected to one side of a feeding plate, the bottom of the feeding plate is slidably connected to the top of a cutting table, a fixing block is fixedly connected to the top of the cutting table, a D-shaped groove is provided at the top of the fixing block, the inner wall of the D-shaped groove is slidably connected to the outer wall of the telescopic bolt, and the D-shaped groove is used to guide the telescopic bolt to move back and forth when it moves left and right.
[0010] Preferably, the D-shaped groove includes a straight groove and an arc groove. The straight groove is located in front of the arc groove and they are connected end to end. The straight groove rises from right to left, and the arc groove rises from left to right. That is, on the right side of the D-shaped groove, the arc groove is higher than the straight groove. After the telescopic bolt falls from the arc groove into the straight groove, it can only move along the straight groove from right to left. At this time, the feeding plate is at the front end and is always in contact with the injection molded part. On the left side of the D-shaped groove, the straight groove is higher than the arc groove. After the telescopic bolt falls from the straight groove into the arc groove, it can only move along the arc groove from left to right. At this time, the feeding plate is not in contact with the injection molded part.
[0011] Compared with the prior art, the advantages of this utility model are as follows:
[0012] This invention uses a motor to move the feeding plate from right to left, which in turn moves the injection molded part from right to left until it is accurately positioned below the injection molded part slitting machine. The injection molded part slitting machine is then started to cut the part. As the motor continues to rotate, it moves the feeding plate to the far right and into close contact with the part. The motor continues to rotate, causing the feeding plate to push the part to the next cutting position, which is then accurately positioned below the injection molded part slitting machine. This process is repeated, ensuring that each injection molded part is precisely placed in the designated position on the cutting equipment. This avoids inaccurate cutting positions, which can affect the cutting quality of the injection molded part and cause problems such as dimensional deviations and uneven cuts. Furthermore, the feeding speed is uniform, improving production efficiency.
[0013] This invention utilizes a telescopic rod that moves the feed plate from right to left along the straight groove of the D-shaped groove, and a telescopic bolt that moves along the arc groove of the D-shaped groove, when the feed plate moves from left to right. The telescopic bolt moves backward and then forward along the inner wall of the telescopic groove. The telescopic bolt, through the telescopic rod, moves the feed plate backward and then forward, thus ensuring that the feed plate does not contact the injection molded part when returning from left to right until it reaches the far right and then makes close contact with the injection molded part. This prevents the injection molded part from moving to the right, which could cause the cutting position to be inaccurately located below the injection molded part cutting machine.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0024] Please see Figure 1-8A slitting device for injection molded parts includes a slitting table 1, which serves as the main body of the device, supporting other components and providing a platform for slitting operations. An injection molded part slitting machine 2 is movably connected to the outer wall of the slitting table 1. The injection molded part slitting machine 2 is connected to an external power source and can move left and right. This is the main component for slitting injection molded parts, as described in the prior art. It achieves fixed-length cutting of the injection molded parts using cutting blades. A mounting plate 3 is fixedly connected to the outer wall of the slitting table 1. A motor 4 is fixedly connected to the top of the mounting plate 3. The motor 4 is a three-phase asynchronous motor connected to an external power source, providing power to drive the rotation of a support frame 5 and components such as a middle circular block 6, an inner circular ring 7, and an outer circular ring 8. The top of the output shaft of the motor 4 is fixedly connected to the support frame 5, which is connected to the output shaft of the motor 4. The shaft and components such as the middle circular block 6, inner ring 7, and outer ring 8 transmit the power of the motor 4. The top of the support frame 5 is fixedly connected to the middle circular block 6, inner ring 7, and outer ring 8, which serve as the sliding rails for the moving bolt 12. By changing the position of the moving bolt 12 on these rings, the left and right movement of the L-shaped rod 11 and the loading plate 13 is achieved. A notch is provided on the inner ring 7, through which the moving bolt 12 changes position. The top of the middle circular block 6 is fixedly connected to the inner stop bolt 20, which is used to fix the initial position of the inner guide plate 15. The top of the outer ring 8 is fixedly connected to the outer stop bolt 21, which is used to fix the initial position of the outer guide plate 18. The outer wall of the cutting table 1 is fixedly connected to the limit plate 9. A limiting groove 10 is provided in the wall, which provides a sliding track for the L-shaped rod 11, restricting its sliding direction. The L-shaped rod 11 is slidably connected to the inner wall of the limiting groove 10. The L-shaped rod 11 is slidably connected in the limiting groove 10, connected to the movable bolt 12, and drives the feeding plate 13 to move left and right. The L-shaped rod 11 and the limiting groove 10 are connected by a sliding block, so that the L-shaped rod 11 can only slide left and right in the limiting groove 10 and cannot move back and forth. That is, the back and forth position of the movable bolt 12 will not change, only left and right. One end of the L-shaped rod 11 is fixedly connected to the movable bolt 12. The movable bolt 12 slides in the grooves on the middle circular block 6, the inner circular ring 7, and the outer circular ring 8, changing the position of the L-shaped rod 11. The outer wall of the movable bolt 12 slides with the middle circular block 6, the inner circular ring 7, and the outer circular ring 8. The position of the L-shaped rod 11 can be changed by altering the position of the movable bolt 12 on the middle circular block 6, inner ring 7, and outer ring 8. When the movable bolt 12 is located in the groove between the middle circular block 6 and the inner ring 7, the L-shaped rod 11 is located on the far right of the limiting groove 10. When the movable bolt 12 is located in the groove between the inner ring 7 and the outer ring 8, the L-shaped rod 11 is located on the far left of the limiting groove 10. The L-shaped rod 11 drives the feeding plate 13 to move via a telescopic mechanism. The feeding plate 13 moves from right to left, pushing the injection molded part to be fed and cut. The telescopic mechanism is used to prevent the feeding plate 13 from contacting the injection molded part when it returns from left to right. By starting the motor 4, the feeding plate 13 is driven to move from right to left, and the feeding plate 13 moves the injection molded part from right to left until it is accurately positioned below the injection molded part cutting machine 2.The injection molding slitting machine 2 is started to cut the injection molded parts. The motor 4 continues to rotate, driving the feeding plate 13 to the far right, where it makes close contact with the injection molded parts. The motor 4 then continues to rotate, causing the feeding plate 13 to push the injection molded parts to the next cutting position, accurately placing them below the injection molding slitting machine 2. This process repeats, ensuring that each injection molded part is precisely placed in the designated position on the cutting equipment. This avoids inaccurate cutting positions, which can affect the cutting quality, causing dimensional deviations, uneven cuts, and other problems. Furthermore, the feeding speed is uniform, improving production efficiency.
[0025] Please see Figure 3-5 A rotating shaft 14 is rotatably connected to the top of the middle circular block 6. An inner guide plate 15 is fixedly connected to the top of the rotating shaft 14. A first torsion spring 16 is sleeved on the outer wall of the rotating shaft 14. The two ends of the first torsion spring 16 are fixedly connected to the opposite sides of the middle circular block 6 and the inner guide plate 15, respectively. When the inner guide plate 15 contacts the moving bolt 12, the moving bolt 12 will move along the inclined side of the inner guide plate 15 from the groove between the middle circular block 6 and the inner ring 7 to the groove between the inner ring 7 and the outer ring 8. This process causes the feeding plate 13 to move from right to left. A rotating shaft 17 is rotatably connected to the top of the outer ring 8. An outer guide plate 18 is fixedly connected to the top of the rotating shaft 17. A second torsion spring 19 is sleeved on the outer wall of the rotating shaft 17. The two ends of 19 are fixedly connected to the opposite sides of the outer ring 8 and the outer guide plate 18, respectively. When the outer guide plate 18 contacts the movable bolt 12, the movable bolt 12 will move along the inclined side of the outer guide plate 18 from the groove between the inner ring 7 and the outer ring 8 to the groove between the middle block 6 and the inner ring 7. This process causes the feeding plate 13 to move from left to right. The inner guide plate 15 and the outer guide plate 18 are connected to the middle block 6 and the outer ring 8 through the rotating shaft 14 and the rotating shaft 17, providing guidance for the movable bolt 12 and pushing it to slide into the adjacent groove. The first torsion spring 16 and the second torsion spring 19 provide the restoring force for the inner guide plate 15 and the outer guide plate 18, respectively, to ensure that they can return to the initial position after contacting the movable bolt 12.
[0026] Please see Figure 6-8The telescopic mechanism includes a telescopic rod 22, the outer wall of which is slidably connected to one end of an L-shaped rod 11. A telescopic bolt 23 is slidably connected to the bottom of the telescopic rod 22. A compression plate 24 is fixedly connected to the outer wall of the telescopic bolt 23. A spring 25 is sleeved on the outer wall of the telescopic bolt 23. The top of the spring 25 is slidably connected to the bottom of the L-shaped rod 11, and the bottom of the spring 25 is fixedly connected to the top of the compression plate 24. A telescopic groove 26 is formed at the bottom of the L-shaped rod 11, and the inner wall of the telescopic groove 26 is slidably connected to the outer wall of the telescopic bolt 23. One end of the telescopic rod 22 is fixedly connected to one side of a feeding plate 13. The bottom of the feeding plate 13 is slidably connected to the top of a cutting table 1. A fixing block 27 is fixedly connected to the top of the cutting table 1. A D-shaped groove 28 is formed at the top of the fixing block 27. The D-shaped groove 28 guides the telescopic bolt 23 to move back and forth when moving left and right, ensuring that the feeding plate 13 can move according to the direction of movement. Moving along a predetermined path, the inner wall of the D-groove 28 is slidably connected to the outer wall of the telescopic bolt 23. The D-groove 28 is used to guide the telescopic bolt 23 to move back and forth when it moves left and right. When the feeding plate 13 moves from right to left, the telescopic rod 22 drives the telescopic bolt 23 to move from right to left along the straight groove of the D-groove 28. When the feeding plate 13 moves from left to right, the telescopic rod 22 drives the telescopic bolt 23 to move from left to right along the arc groove of the D-groove 28. The telescopic bolt 23 will move backward and then forward along the inner wall of the telescopic groove 26. The telescopic bolt 23 drives the feeding plate 13 to move backward and then forward through the telescopic rod 22. This allows the feeding plate 13 to return from left to right without contacting the injection molded part until the feeding plate 13 moves to the far right and then makes close contact with the injection molded part. This avoids moving the injection molded part to the right, which would cause the cutting position to be inaccurately located below the injection molded part cutting machine 2.
[0027] Please see Figure 8 The D-shaped groove 28 includes a straight groove and an arc groove. The straight groove is located in front of the arc groove and they are connected end to end. The straight groove rises from right to left, and the arc groove rises from left to right. That is, on the right side of the D-shaped groove 28, the arc groove is higher than the straight groove. After the telescopic bolt 23 falls from the arc groove into the straight groove, it can only move along the straight groove from right to left. At this time, the feeding plate 13 is at the front end and is always in contact with the injection molded part. On the left side of the D-shaped groove 28, the straight groove is higher than the arc groove. After the telescopic bolt 23 falls from the straight groove into the arc groove, it can only move along the arc groove from left to right. At this time, the feeding plate 13 is not in contact with the injection molded part.
[0028] In use, the operator places the injection molded part to be cut between the loading plate 13 and the front baffle on the cutting table 1. The movable bolt 12 is located in the groove between the middle block 6 and the inner ring 7. At this time, the loading plate 13 is located on the far right, the spring 25 in the telescopic mechanism is in its natural state, and the telescopic bolt 23 is located in the right straight groove of the D-shaped groove 28. The telescopic rod 22 and the loading plate 13 are also in their initial positions. The motor 4 is started, and the motor 4 drives the support frame 5 to rotate. The support frame 5 drives the middle block 6, the inner ring 7, the outer ring 8, and the inner guide plate 15 and the outer guide plate 18 above to rotate synchronously. When the inner guide plate 15 rotates until its inclined side contacts the movable bolt 12, the movable bolt 12 will push the inner guide plate 15 to rotate around the rotation axis 14. Simultaneously, the first torsion spring 16 is twisted, and the movable bolt 12 moves along the inclined side of the inner guide plate 15 from the notch on the inner ring 7 to the groove between the inner ring 7 and the outer ring 8. During this process, the movable bolt 12 drives the L-shaped rod 11 to slide from right to left along the inner wall of the limiting groove 10. Then, due to the reciprocating nature of the first torsion spring 16, the inner guide plate 15 returns to its original position and contacts the inner stop bolt 20. The L-shaped rod 11 drives the feeding plate 13 to move from right to left through the telescopic rod 22. At the same time, the telescopic rod 22 drives the telescopic bolt 23 to move from right to left along the straight groove of the D-shaped groove 28. During the movement, the compression plate 24 will compress the spring 25 upward until the telescopic bolt 23 moves into the leftmost arc groove of the D-shaped groove 28. At this time, the spring 25 will return, and the feeding will resume. Plate 13 moves the injection molded part from right to left a certain distance until the cutting position is accurately located below the injection molded part cutting machine 2. The injection molded part cutting machine 2 is started to cut the injection molded part. The motor 4 continues to rotate, driving the outer guide plate 18 to rotate until its inclined edge contacts the moving bolt 12. The moving bolt 12 pushes the outer guide plate 18 to rotate around the rotating shaft 17 as the center, while simultaneously twisting the second torsion spring 19. The moving bolt 12 moves along the inclined edge of the outer guide plate 18 from the notch on the inner ring 7 to the groove between the middle ring block 6 and the inner ring 7. During this process, the moving bolt 12 drives the L-shaped rod 11 to slide from left to right along the inner wall of the limiting groove 10. Then, due to the reciprocating nature of the second torsion spring 19, the outer guide plate 18 returns to its original position until it contacts the outer stop bolt 21. Rod 11 drives the loading plate 13 to move from left to right via telescopic rod 22. At the same time, telescopic rod 22 drives telescopic bolt 23 to move from left to right along the arc groove of D-shaped groove 28. During the movement, compression plate 24 will compress spring 25 upward, and telescopic bolt 23 will move backward and then forward along the inner wall of telescopic groove 26. Telescopic bolt 23 drives loading plate 13 to move backward and then forward via telescopic rod 22, so that loading plate 13 does not contact the injection molded part when it returns from left to right until loading plate 13 moves to the far right and then makes close contact with the injection molded part. The motor 4 continues to rotate, which will cause loading plate 13 to push the injection molded part to move a certain distance to the next cutting position, accurately located below the injection molded part cutting machine 2, and then cut.
[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
