Description

Technical Field

[0001] This utility model relates to the field of mold clamping technology, specifically a vibration suppression clamp for mold processing. Background Technology

[0002] A fixture is a device used in mechanical manufacturing to fix a workpiece in the correct position for construction or inspection. It is also called a clamp. In a broader sense, any device used to quickly, conveniently and safely install a workpiece in any step of the process can be called a fixture.

[0003] Currently, commonly used clamps typically fix the mold by directly driving the clamping plate with a motor, which is relatively simple. When the mold is fixed on the table, it can stabilize the mold and the whole structure, which can greatly suppress the vibration generated by the mold during operation and further improve product quality.

[0004] Traditional clamps are typically only suitable for a single mold when used to clamp and fix it. When the size and dimensions of the mold change, the clamp must be replaced, which is inconvenient. Therefore, a multi-functional clamping fixture for plastic mold processing is proposed to address the above problems. Utility Model Content

[0016] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] Please see Figures 1-4This utility model provides a technical solution: a vibration suppression fixture for mold processing, including a base 1. Eight guide rails 10 are provided on the upper surface of the base 1. The guide rails 10 can limit and guide the sliding of the screw 12. Every two guide rails 10 form a group, and four groups of guide rails 10 are arranged in a circular center symmetrical arrangement on the upper surface of the base 1 to ensure that the four rubber plates 15 can contact the four sides of the mold 2, thereby improving the clamping force. A motor 3 is fixedly connected to the inner wall of the base 1. The output end of the motor 3 is fixedly connected to one end of the lead screw 4. The other end of the lead screw 4 is rotatably connected to the inner wall of the base 1 through an interference fit of a bearing. After the motor 3 is started, the motor 3 can drive the lead screw 4 to rotate.

[0018] After placing the mold 2 on the upper end of the base 1, start the motor 3. At this time, the lead screw 4 rotates, thereby driving the sleeve 5 to change its state. This allows the rubber plate 15 to approach the mold 2 and fix it. After fixing, the vibration generated during operation can be suppressed.

[0019] The inner wall of the sleeve 5 is threadedly connected to the surface of the lead screw 4. When the lead screw 4 rotates, the sleeve 5 begins to change state. The surface of the sleeve 5 is evenly rotated and connected to one end of the four pull rods 6. The pull rods 6 and the sleeve 5 move synchronously. The other end of the pull rod 6 is located on the inner wall of the pull tube 7 and is slidably connected to it, so as to facilitate the adjustment of the position of the clamping plate 11 and thus adapt to molds 2 of different sizes. There are four pull tubes 7. Several through adjustment holes 9 are opened on the surface of the pull tube 7. The position of the pull rod 6 can be observed and adjusted through the adjustment holes 9. A bolt 8 is inserted into the surface of the pull tube 7. The other end of the bolt 8 passes through the adjustment hole 9 and the pull rod 6 in sequence and is threadedly connected to a nut. At this time, the pull rod 6 is fixed in the pull tube 7 and cannot move. The bolt 8 is slidably connected to the pull rod 6. When the nut is rotated and the bolt 8 is removed, the pull rod 6 can slide.

[0020] The mold 2 is measured, and then its position in the tube 7 is changed by sliding the pull rod 6 to change the overall length. Then the bolt 8 is inserted and tightened. At this time, the pull rod 6 and the tube 7 are fixed to each other and cannot slide relative to each other. When the sleeve 5 moves up and down, the pull rod 6 and the tube 7 will also rotate at the same time.

[0021] The ends of the four pull tubes 7 furthest from the sleeve 5 pass through the base 1 and are slidably connected to it. The ends of the pull tubes 7 furthest from the sleeve 5 are rotatably connected to the clamping plate 11. When the sleeve 5 moves up and down, the clamping plate 11 begins to move under the action of the pull rod 6 and the pull tubes 7. The other end of the clamping plate 11 is fixedly connected to a rubber plate 15. The rubber plate 15 can increase the friction between the clamping plate 11 and the mold 2, thereby making their contact more firm. There are eight screws 12, two screws 12 form a group. One end of each group of screws 12 is fixedly connected to a T-shaped block. The width and length of the T-shaped block are both greater than the diameter of the screw 12. The T-shaped block and the guide... The inner wall of the rail 10 is slidably connected. The rail 10 is a T-shaped rail. One end of the rail 10 passes through the base 1, and the other end of the screw 12 passes through the clamping plate 11 and is slidably connected to it. The screw 12 can guide and fix the clamping plate 11. The surface of the screw 12 is threadedly connected to the fixing plate 13. The surface of the fixing plate 13 is fixedly connected to the spring 14. The other end of the spring 14 is in contact with the clamping plate 11. At this time, the elastic force of the spring 14 can be adjusted by rotating the fixing plate 13, so that the height of the clamping plate 11 can be changed. At the same time, in cooperation with the bolt 8, the mold 2 can be clamped at different height positions. The lower side of the mold 2 is in contact with the base 1.

[0022] The height and range of motion of the adjustable clamping plate 11 are adjusted by the cooperation of the fixed plate 13 and the bolt 8. When the sleeve 5 slides down, the clamping plate 11 gradually approaches the mold 2. Through the buffering of the spring 14, the contact position of the rubber plate 15 with the mold 2 can be automatically adjusted to maintain the best contact surface. When using, adjust the position of all clamps 11 first, and then start the motor 3.

[0023] In actual use, remove bolt 8, then pull rod 6 and pull tube 7 to adjust the overall visible length of pull rod 6 and pull tube 7. During this process, clamp 11 will move accordingly. After adjustment, install bolt 8 and tighten it. When it is necessary to adjust the height of clamp 11, rotate fixed plate 13. At this time, spring 14 moves accordingly. The height of clamp 11 can be adjusted by spring 14 and fixed plate 13. When the height of clamp 11 changes, pull rod 6 and pull tube 7 will rotate, and screw 12 will slide along guide rail 10. Then start motor 3. At this time, lead screw 4 will rotate. The drive sleeve 5 moves downward. At the same time, since the clamping plate 11 needs to remain horizontal to clamp the mold 2, the drive tube 7 rotates relative to the clamping plate 11 under the reaction force of the screw 12 supporting the clamping plate 11. This drives the pull rod 6 and the pull tube 7 to rotate together around the hinge point between the pull rod 6 and the drive sleeve 5. At this time, the clamp 11 drives the screw 12 to start sliding along the guide rail 10 and gradually approach the surface of the mold 2. Then the mold 2 can be fixed by the rubber plate 15 to suppress vibration. The whole is easy to use and is suitable for molds 2 of various sizes.

[0024] 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.
