The first slider 6 slides in the first slide groove 4 to ensure the smooth movement of the moving block 7, reduce the friction resistance and shaking during the movement, and ensure that the mold core 14 can be accurately pulled out of the filter housing 3. During the movement of the moving block 7, the elastic force of the spring 5 will act on the first slider 6. Under the action of the elastic force of the spring 5, the mold core 14 can be automatically pulled out of the filter housing 3.

[0023] In one aspect of this embodiment, after the filter housing 3 is mounted on the mounting base 2 on the base plate 1, the second electric push rod 17 is started, and the second electric push rod 17 begins to extend, pushing the second slider 18 connected to one end thereof to move in the second slide groove 16. The sliding of the second slider 18 in the second slide groove 16 has a guiding effect to ensure that the moving direction is accurate. The movement of the second slider 18 drives the movable frame 19 fixedly connected to its upper side to move toward the filter housing 3. As the movable frame 19 approaches, when the rubber block 20 moves to a certain position, it will be stuck in the slot 15 opened on one side surface of the filter housing 3.

[0024] In one aspect of this embodiment, the main function of the handle 21 is to facilitate the operator to carry and move the entire core pulling mechanism. When the core pulling mechanism needs to be installed on the injection molding equipment or removed from the equipment for maintenance, mold replacement, etc., the operator can hold the handles 21 on both sides of the base plate 1 to easily lift and move the entire mechanism. The rubber pad 22 slightly protrudes to the lower side of the base plate 1. When the core pulling mechanism is placed on the workbench of the injection molding equipment, the rubber pad 22 contacts the surface of the workbench, which increases the friction and prevents the core pulling mechanism from sliding during operation, ensuring the accuracy and stability of the core pulling operation. When the core pulling mechanism is installed on the injection molding equipment, the base plate 1 is firmly fixed to the workbench of the injection molding equipment by passing the fixing nails or screws through the fixing holes 23. The protective pad 24 is made of rubber material and is fixedly connected to the front and back sides of the base plate 1. The rubber material has good elasticity and wear resistance. The textured groove 25 can increase the friction of the protective pad 24, which can effectively protect the base plate 1 from external damage such as collision and scratching.

[0025] The working principle of the present utility model is as follows: when the automobile filter housing core pulling mechanism is in use, the inclined guide block 10 drives the connecting block 9, the moving block 7 and the mold core 14 fixed on one side of the moving block 7 to move horizontally along the first slide groove 4 on the bottom plate 1 under the action of the horizontal component force, and the first slider 6 slides in the first slide groove 4, ensuring the smooth movement of the moving block 7, reducing the friction resistance and shaking during the movement, and ensuring that the mold core 14 can be accurately pulled out of the filter housing 3. During the movement of the moving block 7, the elastic force of the spring 5 will act on the first slider 6, and under the elastic force of the spring 5, the mold core 14 can be automatically pulled out of the filter housing 3, and the second electric The push rod 17 begins to extend, pushing the second slider 18 connected to one end thereof to move in the second slide groove 16. The sliding of the second slider 18 in the second slide groove 16 has a guiding effect to ensure that the moving direction is accurate. The movement of the second slider 18 drives the mobile frame 19 fixedly connected to its upper side to move toward the filter housing 3. As the mobile frame 19 approaches, when the rubber block 20 moves to a certain position, it will be stuck in the slot 15 opened on the side surface of the filter housing 3. The shape and size of the rubber block 20 match the slot 15. After being stuck, they can be tightly combined, which plays an auxiliary stabilizing role for the filter housing 3. All electrical equipment in this solution is powered by an external power supply.
