[0002] The clamp for automobile parts injection molding machine is a clamp system specially used for automobile parts production. During the production process, the mold is clamped by a specific clamp to complete the injection molding. It is used to fix and stabilize the injection mold to ensure the accuracy and efficiency of the injection molding process.

[0003] After searching, the Chinese patent document announcement number: CN209320144U discloses a mold clamp for an injection molding machine. The injection molding machine is placed inside the mold placement box through a through groove, and then the control switch is pressed, the two motors start working, and each drives the screw on one side to rotate, so that the two motors make linear motion on the two slide rails respectively, so that the two screws press the injection molding machine, and a rubber pad is fixed at one end of the two screws to prevent the two screws from causing damage to the injection molding machine when the mold clamp for the injection molding machine fixes the injection molding machine. The box door movably connected to the front of the groove through the rotating shaft has a good protective effect on the storage power supply, and is convenient for the staff to inspect and maintain the storage power supply. The second through hole opened on the front of the mold placement box and the connecting flange fixed on the front of the mold placement box facilitate the connection between the injection system of the injection molding machine and the mold clamp for the injection molding machine.

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Reference Figure 1 and Figure 3 The utility model provides an embodiment: a clamp for an automobile parts injection molding machine, comprising a base 1, the base 1 is usually made of metal, provides a counterweight support force for the clamp, and improves stability, the top of the base 1 is fixedly connected to a box body 2, a cavity is arranged inside the box body 2, and a lifting assembly is arranged inside the box body 2, the support rod 3 is slidably connected inside the box body 2, the top of the support rod 3 is fixedly connected to the box body 4, the inside of the box body 4 is fixedly connected to an electric push rod 5, the electric push rod 5 serves as a power source for the clamping assembly of the clamp, the outside of the electric push rod 5 is slidably connected to a connecting piece 6, the inside of the connecting piece 6 is slidably connected to a slider 8, and the two sliders 8 are mutually connected. A sliding plate 9 is fixedly connected to the near side, and a clamping plate 13 is fixedly connected to the right side of the sliding plate 9. There are many protrusions on the clamping side of the clamping plate 13. When an object is clamped, the friction force can be increased and the clamping is more stable. A T-shaped groove 10 is opened inside the adjacent side of the two sliding plates 9, and a T-shaped slider 11 is slidably connected inside the T-shaped groove 10. A pushing block 12 is fixedly connected to the adjacent side of the two T-shaped sliders 11, and the left side of the pushing block 12 is fixedly connected to the driving end of the electric push rod 5. When the pushing block 12 is pulled by the electric push rod 5, the T-shaped slider 11 can apply a pulling force backwards, thereby pulling the sliding plate 9 to move to the middle, driving the clamping plate 13 to complete the clamping.

[0031] Reference Figure 3 The two sliding plates 9 slide on the front and rear sides of the connecting member 6. The sliding plates 9 are fixedly connected with sliders 8 on the upper and lower sides and slide inside the connecting member 6. The outsides of the two clamping plates 13 are slidably connected to the front and rear sides of the connecting member 6. The clamping is completed by moving the clamping plates 13 to the adjacent side.

[0032] Reference Figure 1 and Figure 2The lifting assembly includes a support rod 3, and a plurality of tooth grooves 14 are provided at the front bottom of the support rod 3. A fixed rod 3 21 is fixedly connected inside the box body 2, and a gear 15 is rotatably connected to the outside of the fixed rod 3 21. The fixed rod 3 21 provides support for the gear 15, and the outside of the gear 15 meshes with the outside of the tooth groove 14. A fixed rod 17 is rotatably connected inside the box body 2, and the fixed rod 17 provides support for the gear 2 16. A fixed rod 20 is rotatably connected inside the box body 2, and a gear 2 16 is fixedly connected to the outside of the fixed rod 17. The outside of the gear 15 meshes with the outside of the gear 2 16. When the gear 2 16 rotates, the gear 15 rotates in the opposite direction. A ratchet 18 is fixedly connected to the outside of the fixed rod 17. A pawl 19 is fixedly connected to the outside of the fixed rod 20, and the outside of the pawl 19 meshes with the outside of the ratchet 18. When the pawl 19 is engaged with the ratchet 18 slot, the ratchet 18 is limited in rotation, and the bottom of the support rod 3 contacts the inner wall of the bottom end of the box 2. The right side of the fixed rod 17 is fixedly connected with a crank 1 22, which is the power source of the lifting assembly. The right side of the fixed rod 20 is fixedly connected with a crank 2 7, which can control the direction of the pawl 19 by shaking the crank 2 7. Manually adjusting the limit device can automatically switch the clamp up and down.

[0033] Working principle: First, place the clamp in a suitable position and turn the crank 22 forward, thereby driving the fixed rod 17, the gear 2 16 and the ratchet 18 to rotate around the fixed rod 17, and the pawl 19 on the ratchet 18 meshes with the ratchet 18 in the opposite direction of the slot to limit the ratchet 18, and then drive the gear 15 meshing with the gear 2 16 to rotate backward around the fixed rod 3 21. At this time, the support rod 3 meshing with the other side of the gear 15 is subjected to the upward movement force of the gear 15, thereby sliding and lifting inside the box 2, so that the clamp is suitable for clamping higher and larger molds, thereby improving the applicability of the clamp.

[0034] Secondly, open the electric push rod 5, and through the contraction of the electric push rod 5, pull the push block 12 to slide inside the T-shaped slide groove 10 of the two sliding plates 9. Due to the bevel design on both sides of the push block 12, the T-shaped sliders 11 on both sides apply a pulling force to the sliding plate 9 toward the adjacent side, thereby driving the clamping plate 13 connected to the right side of the sliding plate 9 to move toward the adjacent side to complete the clamping. The electric push rod 5 is used as the driving source, and no manual operation is required, which improves the ease of operation of the clamp and saves labor costs.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
