DETAILED DESCRIPTION
[0020] The technical scheme in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application. Embodiment 1
[0021] As shown in the drawings, Figure 1 - Figure 7 The utility model provides a kind of technical scheme: a clamp for the removal of cylindrical injection molded part, comprising: drive mechanism 1, the side of drive mechanism 1 is provided with fixed mechanism 2, drive mechanism 1 includes slide cylinder 11, the inside of slide cylinder 11 is slidably connected with slide rod 12, the bottom of slide rod 12 is fixedly connected with limit plate 13, the bottom of limit plate 13 is provided with support plate 14, the top of support plate 14 is distributed with four limit rods 15 in rectangle, the side of four limit rods 15 is provided with two cross plates one 16, the side of two cross plates one 16 is provided with cross plate two 17, the middle of four cross plate two 17 is provided with rotating bolt 18, the side of four cross plate two 17 is rotatably connected with arc plate 19.
[0022] In this embodiment, the outer side of the slide rod 12 is slidably connected to the inside of the slide cylinder 11, and the bottom of the slide rod 12 is fixedly connected to the limiting plate 13. The inside of the limiting plate 13 is slidably connected to the outer side of the limiting rod 15, which can restrict the slide rod 12 to only make stable forward and backward displacements when sliding. The top of the support plate 14 is rectangular and fixedly connected to four limiting rods 15. The tops of the four limiting rods 15 are fixedly connected to the bottom of the slide cylinder 11, so that the position of the slide cylinder 11 is fixed. The bottoms of the two cross plates 16 are connected to the bottom of the slide rod 12. The components are rotatably connected via rotating parts. When the slide rod 12 moves upward, it will cause the first cross plate 16 to move accordingly. The top of the second cross plate 17 is rotatably connected to the bottom of the slide cylinder 11 via rotating parts. When the slide rod 12 moves upward, it will pull the second cross plate 17 upward. The top of the first cross plate 16 is rotatably connected to the bottom of the slide cylinder 11 via rotating parts. When the second cross plate 17 moves upward, the first cross plate 16 will not move. The middle part of the second cross plate 17 is rotatably connected to the middle part of the two first cross plates 16 via rotating bolts 18. Therefore, the upward movement of cross plate 17 will change the angle of cross plate 16. The top of cross plate 16 is fixedly connected to the top of the arc plate 19. The arc plate 19 is curved, so it will not damage the shape of the injection molded part when clamping it. The bottoms of the two cross plates 17 are rotatably connected to the bottom of the arc plate 19 through a rotating component. The angle change between cross plate 16 and cross plate 17 will cause the arc plate 19 to move outward. The two arc-shaped plates 19 move outwards simultaneously, which can clamp the inner wall of the cylindrical injection molded part without damaging its shape. The different angles of the first cross plate 16 and the second cross plate 17 can control the position of the arc-shaped plates 19, thereby clamping cylindrical injection molded parts of different sizes. When it is necessary to put down the injection molded part, simply push the slide bar 12 back to reduce the angle between the first cross plate 16 and the second cross plate 17, thereby moving the position of the arc-shaped plates 19 inwards and canceling the clamping of the injection molded part. Example 2
[0023] like Figure 1 - Figure 7 As shown, the fixing mechanism 2 includes an inclined groove 21, a limiting block 22 is provided on one side of the inclined groove 21, two springs 23 are fixedly connected to one side of the limiting block 22, and a moving block 24 is provided on the top of the springs 23.
[0024] In this embodiment, a plurality of inclined grooves 21 are provided on one side of the slide rod 12. The inclined grooves 21 are arranged in a straight line. The bottom of the inclined grooves 21 is inclined, and the top of the inclined grooves 21 is a right-angled plane. A groove is provided inside the top side of the slide cylinder 11. The outer side of the limiting block 22 is slidably connected to the top groove of the slide cylinder 11. The limiting block 22 is rectangular. The outer side of the limiting block 22 is engaged with the inside of the inclined groove 21. Two springs 23 are fixedly connected to the side of the limiting block 22 away from the slide rod 12. The end of the spring 23 away from the limiting block 22 is fixedly connected to the inside side of the slide cylinder 11, so that the limiting block 22 is always pushed by the spring 23 and always in contact with the inside of the inclined groove 21. When the slide rod 12 moves outward, the bottom inclined surface of the inclined groove 21 presses against one side of the limiting block 22. The limiting block 22 is pressed and the springs are engaged. Spring 23 retracts and slides back into the slide cylinder 11. After moving through one inclined groove 21, spring 23 releases its elastic force to push the limiting block 22, causing the limiting block 22 to contact the inside of the next inclined groove 21 until the slide rod 12 stops moving. If the slide rod 12 is pushed inward, the top plane of the inclined groove 21 will press against the top of one side of the limiting block 22. Because the limiting block 22 is rectangular, the inclined groove 21 will be restricted to its original position by the limiting block 22, thus preventing the slide rod 12 from changing its position arbitrarily due to external reasons. When the slide rod 12 needs to be pushed back, it is only necessary to push the moving block 24 fixedly connected to the top of the limiting block 22, so that spring 23 is compressed by force, and the limiting block 22 will move with the moving block 24, thus releasing the restriction on the inclined groove 21.
[0025] Working principle: When the injection molding process is completed and the molded part needs to be removed, support the bottom of the slide cylinder 11 with your hand, insert one side of the drive mechanism 1 into the cylindrical injection part, grasp the handle on one side of the slide rod 12, and pull the slide rod 12 upward. The slide rod 12 moves upward, which will drive the four sets of cross plates 17 arranged in a ring at the bottom to move upward. The cross plates 17 are rotatably connected to the middle of the cross plates 16 via rotating bolts 18. When the cross plates 17 move upward, the cross plates 16 do not move upward, but their angle will change. As the cross plate 17 moves upward, its angle changes, pushing the arc plate 19 on one side outward. All four arc plates 19 move outward until they contact the inner wall of the injection molded part. At this point, the upward pulling of the slide rod 12 stops, and instead, the slide cylinder 11 moves upward. Because the injection molded part is held by the arc plate 19, the upward movement of the slide cylinder 11 will remove the entire injection molded part. After removal, when the injection molded part needs to be lowered, the slide rod 12 is pushed downward. The top plane of the inclined groove 21 on one side of the slide rod 12 presses against the top of the limiting block 22 on one side. Because the top of the limiting block 22... The slide bar 12 is also planar, so it cannot push against the limiting block 22 and will be restricted. The bottom of the inclined groove 21 is inclined. If the slide bar 12 moves upward, the inclined bottom of the slide bar 12 will press against the bottom of one side of the limiting block 22. The limiting block 22 will move outward due to the pressure from the inclined surface, causing the spring 23 fixedly connected on one side to contract, so that the limiting block 22 will be completely retracted into the slide cylinder 11. Therefore, the limiting block 22 only restricts the downward movement of the slide bar 12. When the slide bar 12 moves upward, it will not be restricted by the limiting block 22. To allow the slide bar 12 to move downward... Simply push the moving block 24 outwards, and the moving block 24 will move the limiting block 22, causing the limiting block 22 to slide back into the slide cylinder 11, thereby releasing the restriction on the slide rod 12. At this time, the slide rod 12 can be pushed down. The slide rod 12 moves down, which makes the angle between the bottom cross plate 16 and the cross plate 17 smaller. The smaller angle between the cross plate 16 and the cross plate 17 makes the arc plate 19 move inwards. When the arc plate 19 moves inwards, the outer side will slowly detach from the inner wall surface of the injection molded part, thereby releasing the clamping of the injection molded part. At this time, the injection molded part can be easily removed.
[0026] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
