Description

Technical Field

[0001] This utility model relates to the field of high-precision injection mold locking technology, specifically a high-precision injection mold locking mechanism. Background Technology

[0002] A high-precision injection mold locking mechanism is a device specifically designed to ensure that injection molds maintain precise alignment during the manufacturing process. In injection molding, mold stability directly affects the dimensional accuracy and surface quality of the final product. Therefore, the design and manufacture of a high-precision injection mold locking mechanism are crucial.

[0003] Currently widely used locking devices generally rely on auxiliary installation parts such as bolts during the installation process. These parts need to firmly fix the equipment to the mold. To achieve this, it is usually necessary to make holes or perform other similar machining operations on the mold body. However, this approach inevitably causes some damage to the structural integrity of the mold, increases the risk of mold damage, and may even affect its service life and accuracy. Therefore, this traditional installation method has certain limitations in practical applications. Utility Model Content

[0004] The purpose of this invention is to provide a high-precision injection mold locking mechanism to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: It includes an injection mold assembly, on which a first clamping assembly and a second clamping assembly are installed from bottom to top on the front and rear sides. A winding assembly is installed on one side of the second clamping assembly, and a connecting assembly is installed on the other side of the second clamping assembly. The winding assembly includes a collection box, a traction belt, a winding rod, a receiving sleeve, a coil spring, and a hook. The traction belt is installed inside the collection box, and a winding rod is installed inside the traction belt. A receiving sleeve is provided below the collection box, and a coil spring is installed inside the receiving sleeve. A hook is connected to the end of the traction belt away from the collection box, and a connecting assembly is connected to the hook.

[0006] Preferably, the injection mold assembly includes an upper high-precision template and a lower high-precision template, and the lower high-precision template is provided below the upper high-precision template; By adopting the above technical solution, a complete injection molding template is formed, which facilitates the reference for equipment installation.

[0007] Preferably, the first clamping assembly includes a central support frame, a hook plate, a first spring, a first guide rod, and a clamping plate. The hook plate is installed below the central support frame, the middle of the left and right sides of the central support frame is connected to the first spring, and the upper and lower ends of the left and right sides of the central support frame are installed with the first guide rod. The end of the first spring away from the central support frame is connected to the clamping plate. By adopting the above technical solution, the equipment can be initially clamped and installed.

[0008] Preferably, the connecting assembly includes a hook rod and a fixing block, and fixing blocks are installed on the upper and lower sides of the hook rod; By adopting the above technical solution and cooperating with the winding assembly, the equipment can be reinforced and clamped for secondary installation.

[0009] Preferably, a traction component is installed at the end of the second clamping component away from the injection mold component, and the traction component includes a receiving box, a lifting plate, a second guide rod, a traction rope, a fixed pulley, a second spring and a first electromagnet. The lifting plate is installed inside the receiving box, and the second guide rod is installed at both ends of the lifting plate. The upper end of the lifting plate is connected to the traction rope, and the fixed pulley is connected to the traction rope. The lower end of the lifting plate is connected to the second spring, and the lower end of the second spring is connected to the first electromagnet. By adopting the above technical solution, the auxiliary fixing component can be pulled to make it work.

[0010] Preferably, the lower end of the traction component is connected to a lower fixing component, and the lower fixing component includes an inverted triangular fixing block and a second electromagnet, wherein the second electromagnet is installed on the inverted triangular fixing block; By adopting the above technical solution, it is possible to connect with the traction component by magnetic attraction and perform the first locking of the equipment.

[0011] Preferably, auxiliary fixing components are installed on the left and right sides of the traction component, and the auxiliary fixing components include a movable plate, a triangular block, a third guide rod and a third spring. The lower end of the movable plate is equipped with a triangular block, and the upper end of the movable plate is through-mounted with a third guide rod. The third guide rod is equipped with a third spring on its outside. By adopting the above technical solution, it can be used in conjunction with the lower fixing component to perform auxiliary locking and increase the locking effect.

[0012] Compared with the prior art, the advantages of this application are: the equipment does not need to cause a certain degree of damage to the structural integrity of the mold, reducing the risk of mold damage and not affecting its service life and accuracy. The equipment will still apply clamping force when locking, which will ensure the stability of the equipment after locking and prevent the locking from loosening.

[0013] This utility model connects to the connecting component via a hook, and uses the elasticity of the coil spring to cause the winding rod to rewind the traction belt in real time, thereby stably fixing both the first clamping component and the second clamping component to the injection mold component. The above fixing method does not damage the injection mold component and can ensure the stability of the fixation. This invention achieves a locking effect through the attraction between the first and second electromagnets. At the same time, the inclined structure between the triangular block and the inverted triangular fixing block, along with the elasticity of the second spring, keeps the connection between the traction component and the lower fixing component stable, thus ensuring a stable docking state for the injection mold component.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-3This utility model provides a technical solution: including an injection mold assembly 1, with a first clamping assembly 2 and a second clamping assembly 3 installed from bottom to top on the front and rear sides of the injection mold assembly 1, and a winding assembly 4 installed on one side of the second clamping assembly 3, and a connecting assembly 5 installed on the other side of the second clamping assembly 3. The winding assembly 4 includes a collection box 401, a traction belt 402, a winding rod 403, a receiving sleeve 404, a coil spring 405, and a hook 406. The traction belt 402 is installed inside the collection box 401, and the winding rod 403 is provided inside the traction belt 402. The receiving sleeve 404 is provided below the collection box 401, and the coil spring 405 is installed inside the receiving sleeve 404. The end of the traction belt 402 away from the collection box 401 is connected to the hook 406, and the connecting assembly 5 is connected to the hook 406. The winding rod 403 forms an elastic rotation structure with the receiving sleeve 404 through the coil spring 405. Through the elastic rotation structure, the traction belt 402 can be continuously wound up and wound into the collection box 401. This will cause the traction belt 402 to form a stable traction force on the hook 406, and stably pull the connecting assembly 5, so that the two second clamping assemblies 3 or the first clamping assembly 2 can be connected together. The hook 406 is connected to the connecting component 5, and the elasticity of the coil spring 405 causes the winding rod 403 to wind up the traction belt 402 in real time, thereby stably fixing the first clamping component 2 and the second clamping component 3 to the injection mold component 1. The above fixing method does not cause damage to the injection mold component 1 and can ensure the stability of the fixation.

[0018] Injection mold assembly 1 includes an upper high-precision template 101 and a lower high-precision template 102, and the lower high-precision template 102 is provided below the upper high-precision template 101.

[0019] The first clamping assembly 2 includes a middle support frame 201, a hook plate 202, a first spring 203, a first guide rod 204, and a clamping plate 205. The hook plate 202 is installed below the middle support frame 201. The first spring 203 is connected to the middle of the left and right sides of the middle support frame 201. The first guide rod 204 is installed at the upper and lower ends of the left and right sides of the middle support frame 201. The clamping plate 205 is connected to the end of the first spring 203 away from the middle support frame 201. The clamping plate 205 forms an elastic structure with the middle support frame 201 through the first guide rod 204 and the first spring 203. The elastic structure enables the clamping plate 205 to clamp the lower high-precision template 102. Thus, the equipment is clamped and installed onto the injection mold assembly 1 through the first clamping assembly 2 and the second clamping assembly 3. The hook plate 202 can increase the vertical force on the equipment, making it easy to tightly connect the upper high-precision template 101 and the lower high-precision template 102 when they are separated or merged.

[0020] The connecting component 5 includes a hook rod 501 and a fixing block 502, and the fixing block 502 is installed on the upper and lower sides of the hook rod 501. The hook rod 501 is fixed by the fixing block 502. The shape of the hook rod 501 makes it easy for the hooks 406 to hook together, so that the two first clamping components 2 or the two second clamping components 3 can be connected by the structure of the winding component 4 and the connecting component 5.

[0021] The second clamping assembly 3 is equipped with a traction assembly 6 at the end away from the injection mold assembly 1. The traction assembly 6 includes a housing 601, a lifting plate 602, a second guide rod 603, a traction rope 604, a fixed pulley 605, a second spring 606, and a first electromagnet 607. The lifting plate 602 is installed inside the housing 601. The second guide rod 603 is installed at both ends of the lifting plate 602. The upper end of the lifting plate 602 is connected to the traction rope 604, and the fixed pulley 605 is connected to the traction rope 604. The lower end of the lifting plate 602 is connected to the second spring 606, and the lower end of the second spring 606 is connected to the first electromagnet 607. The lifting plate 602 forms a sliding structure with the receiving box 601 through the second guide rod 603. The attraction between the first electromagnet 607 and the second electromagnet 702 causes the second spring 606 to pull the lifting plate 602, thereby causing the lifting plate 602 to pull the auxiliary fixing component 8 through the traction rope 604. This facilitates the connection between the auxiliary fixing component 8 and the lower fixing component 7, locking the equipment. The fixed pulley 605 facilitates the turning of the traction rope 604.

[0022] The lower end of the traction component 6 is connected to the lower fixing component 7, and the lower fixing component 7 includes an inverted triangular fixing block 701 and a second electromagnet 702. The second electromagnet 702 is installed on the inverted triangular fixing block 701. The attraction between the first electromagnet 607 and the second electromagnet 702 creates a locking effect. At the same time, the inclined structure between the triangular block 802 and the inverted triangular fixing block 701, along with the elasticity of the second spring 606, keeps the connection between the traction component 6 and the lower fixing component 7 stable, thus keeping the injection mold component 1 in a stable docking state.

[0023] Auxiliary fixing components 8 are installed on the left and right sides of the traction component 6. The auxiliary fixing components 8 include a movable plate 801, a triangular block 802, a third guide rod 803 and a third spring 804. The lower end of the movable plate 801 is equipped with the triangular block 802, and the upper end of the movable plate 801 is through-installed with the third guide rod 803. The third spring 804 is installed on the outside of the third guide rod 803. The movable plate 801 is easily reset when the traction rope 604 does not pull the movable plate 801, thanks to the elastic structure formed between the movable plate 801 and the housing 601 through the third guide rod 803 and the third spring 804.

[0024] The implementation principle of this application is as follows: First, the two first clamping components 2 are clamped on both sides of the lower high-precision template 102 respectively. Then, the winding component 4 is connected to the connecting component 5, so that the first clamping component 2 is stably installed on the lower high-precision template 102. Similarly, the second clamping component 3 is installed so that the second clamping component 3 is stably installed on the upper high-precision template 101. Then, when the upper high-precision template 101 and the lower high-precision template 102 are connected, the second electromagnet 702 and the first electromagnet 607 will be opened. The first electromagnet 607 and the second electromagnet 702 will be attracted and connected together by magnetism. At this time, the first electromagnet 607 will pull the second spring 606 downward, so that the lifting plate 602 moves. The auxiliary fixing component 8 is clamped on both sides of the lower fixing component 7 by the traction rope 604 to achieve the locking effect.
