Description

Technical Field

[0001] This utility model relates to the field of rotary core-pulling mold technology, specifically a locking mechanism for a rotary core-pulling mold. Background Technology

[0002] In the injection molding process, the mold plays a crucial role, and the rotary core-pulling mold can adapt to the production needs of plastic products with complex internal structures, such as automotive parts and home appliance parts.

[0003] When existing rotary core-pulling molds are installed on production equipment, multiple sets of bolts are used to firmly fix the molds to the production equipment to ensure that the rotary core-pulling molds are firmly locked on the production equipment during product production, thereby ensuring the stable operation of the molds during use.

[0004] However, when installing the mold, workers need to use specialized tools to tighten multiple sets of bolts to ensure a tight fit between the mold and the production equipment. When the mold needs to be replaced to meet the production requirements of different products, workers have to use tools again to remove each bolt one by one in order to remove the old mold from the production equipment. This process is not only time-consuming and labor-intensive, but also greatly prolongs the mold replacement time and reduces the overall efficiency of the production line. Utility Model Content

[0005] The purpose of this invention is to provide a locking mechanism for a rotary core-pulling mold, so as to solve the problem mentioned in the background art that it is time-consuming and labor-intensive to install the mold on the production equipment.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A locking mechanism for a rotary core-pulling mold includes: a mounting plate on which a mold body is mounted; a locking component on the mounting plate, comprising a limiting plate and a spring; the limiting plate on the mold body having a fixing hole; the spring on the mounting plate with a fixing post; the fixing post having a limiting groove; and a buffer plate within the limiting groove. The locking component is used for mounting the mold body. A replacement component on the buffer plate includes an elastic retaining plate on the buffer plate, and a placement groove within the limiting groove. The replacement component is used for replacing the buffer plate.

[0008] Preferably, the locking assembly further includes a slider disposed at one end of the spring, the slider being slidably disposed in a corresponding groove on the mounting plate, a connecting plate being disposed at the top of the slider, a T-shaped block being disposed at the bottom of the connecting plate, a T-shaped groove being disposed on the mounting plate corresponding to the T-shaped block, the T-shaped block being movably disposed in the T-shaped groove, a telescopic rod being disposed between the mounting plate and the fixing post, the telescopic rod being disposed on the inner side of the spring.

[0009] Preferably, two sets of fixing posts are symmetrically arranged on the side of the connecting plate away from the spring. The fixing posts are slidably arranged in the limiting groove and penetrate the limiting groove. The limiting plate matches the limiting groove. The limiting plate is provided with fixing holes corresponding to the fixing posts. The fixing holes match the fixing posts.

[0010] Preferably, a fixing strip is provided on one side of the connecting plate, a telescopic plate is provided in the middle of the fixing strip, a connecting column is fixedly installed on the telescopic plate, and a through hole is provided on the fixing strip corresponding to the connecting column, and the connecting column is movably disposed in the through hole.

[0011] Preferably, the mounting plate has a circular groove corresponding to the connecting post, and an elastic element is fixedly installed in the circular groove. One end of the elastic element is provided with a sliding cylinder, which matches the through hole.

[0012] Preferably, the replacement component also includes a storage slot located in the middle of the buffer plate, a handle is movably installed inside the storage slot, one end of the handle is provided with a slide bar, and the slide bar passes through the storage slot.

[0013] Preferably, a connecting block is provided at the end of the slide bar away from the handle, and both ends of the connecting block are rotatably connected to cranks, which are rotatably connected to the elastic plate.

[0014] Preferably, two sets of elastic retaining plates are symmetrically arranged on the buffer plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] When the mold body needs to be installed on the production equipment, the operator controls the limiting plate to be aligned with the limiting groove and inserted, so that the fixing hole is aligned with the fixing post. The spring force can make the fixing post firmly locked in the fixing hole, realizing the quick locking of the mold body. The buffer plate can prevent the mold body from hitting the mounting plate.

[0017] When the buffer plate becomes damaged after a long period of time, the staff can pull the handle to make the two sets of elastic plates retract inward at the same time, which makes it easier for the staff to take out the buffer plate from the placement slot. The new buffer plate can be quickly installed by aligning it with the placement slot, which can greatly improve the replacement speed of the buffer plate. Attached Figure Description

[0028] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0030] like Figure 1 - Figure 9As shown, this application provides a locking mechanism for a rotary core-pulling mold, including: a mounting plate 1, on which a mold body 2 is disposed, and a locking assembly on the mounting plate 1, the locking assembly including a limiting plate 6 and a spring 17, the limiting plate 6 being disposed on the mold body 2, the limiting plate 6 being provided with a fixing hole 8, the spring 17 being disposed on the mounting plate 1, the spring 17 being provided with a fixing post 10, the fixing post 10 being provided with a limiting groove 7, and a buffer plate 9 being disposed in the limiting groove 7, the locking assembly being used for mounting the mold body 2.

[0031] Specifically, such as Figure 6 As shown, the locking assembly also includes a slider 15 disposed at one end of the spring 17. The slider 15 is slidably disposed in a corresponding groove on the mounting plate 1. A connecting plate 3 is disposed at the top of the slider 15, and a T-shaped block 12 is disposed at the bottom of the connecting plate 3. A T-shaped groove 11 is disposed on the mounting plate 1 corresponding to the T-shaped block 12. The T-shaped block 12 is movably disposed in the T-shaped groove 11. A telescopic rod 16 is disposed between the mounting plate 1 and the fixed post 10. The telescopic rod 16 is disposed inside the spring 17. Through the cooperation of the T-shaped block 12 and the T-shaped groove 11, the movement direction of the fixed post 10 can be limited, preventing the fixed post 10 from detaching from the mounting plate 1.

[0032] Specifically, such as Figure 4 As shown, two sets of fixing posts 10 are symmetrically arranged on the side of the connecting plate 3 away from the spring 17. The fixing posts 10 are slidably arranged in the limiting groove 7 and pass through the limiting groove 7. The limiting plate 6 matches the limiting groove 7. The limiting plate 6 is provided with fixing holes 8 corresponding to the fixing posts 10. The fixing holes 8 match the fixing posts 10. Through the cooperation of the fixing posts 10 and the fixing holes 8, the mold body 2 can be firmly fixed on the mounting plate 1.

[0033] Specifically, such as Figure 6 As shown, a fixing strip 4 is provided on one side of the connecting plate 3, and a telescopic plate 18 is provided in the middle of the fixing strip 4. A connecting column 19 is fixedly installed on the telescopic plate 18. A through hole 20 is provided on the fixing strip 4 corresponding to the connecting column 19. The connecting column 19 is movably disposed in the through hole 20. With the setting of the telescopic plate 18, it is convenient for the staff to drive the fixing column 10 to move away from the placement groove 14.

[0034] Specifically, such as Figure 6 As shown, a circular groove 21 is provided on the mounting plate 1 corresponding to the connecting post 19. An elastic element 23 is fixedly installed in the circular groove 21. A sliding cylinder 22 is provided at one end of the elastic element 23. The sliding cylinder 22 matches the through hole 20. Through the elastic force of the elastic element 23, the sliding cylinder 22 can lift the connecting post 19 in the through hole 20, so that the sliding cylinder 22 can be firmly stuck in the through hole 20, thereby fixing the position of the connecting plate 3.

[0035] The buffer plate 9 is provided with a replacement component, which includes an elastic retaining plate 13 provided on the buffer plate 9 and a placement slot 14 provided in the limiting groove 7. The replacement component is used to replace the buffer plate 9.

[0036] Specifically, such as Figure 8 As shown, the replacement component also includes a storage slot 5 located in the middle of the buffer plate 9. A handle 27 is movably installed inside the storage slot 5. A slide rod 24 is provided at one end of the handle 27 and passes through the storage slot 5. The storage slot 5 is designed to prevent the handle 27 from affecting the normal operation of the buffer plate 9.

[0037] Specifically, such as Figure 9 As shown, a connecting block 25 is provided at one end of the slide bar 24 away from the handle 27. Both ends of the connecting block 25 are rotatably connected to cranks 26. The cranks 26 are rotatably connected to the elastic plate 13. Through the setting of the elastic plate 13, the buffer plate 9 can be firmly fixed in the limiting groove 7.

[0038] Specifically, such as Figure 9 As shown, two sets of elastic retaining plates 13 are symmetrically arranged on the buffer plate 9. The stability of the buffer plate 9 within the limiting groove 7 can be increased by the two sets of elastic retaining plates 13.

[0039] In this embodiment: the limiting plate 6 is aligned with the limiting groove 7 to achieve pre-positioning of the mold body 2. The spring force of the spring 17 can make the fixing post 10 firmly locked in the fixing hole 8, thereby locking the mold body 2 and preventing the mold body 2 from shaking during operation, so that the mold body 2 can work stably. The buffer plate 9 is provided inside the limiting groove 7, which can reduce the collision force between the mold body 2 and the mounting plate 1 when installing the mold body 2, thereby preventing damage to the mold body 2. When the buffer plate 9 is damaged, the operator can pull the handle 27 to drive the slide rod 24 to slide, thereby driving the two sets of elastic clamping plates 13 to rotate inward at the same time, so that the elastic clamping plates 13 can be disengaged from the placement groove 14, which facilitates the operator to quickly replace the buffer plate 9 and effectively prevents the buffer plate 9 from affecting the installation of the mold body 2.

[0040] The specific solution is as follows: When the mold body 2 needs to be installed on the production equipment, since the mounting plate 1 is fixed on the production equipment, and since the initial state of the fixing column 10 is through the limiting groove 7, the operator first pulls the telescopic plate 18 to drive the fixing column 10 away from the limiting groove 7. By pulling the telescopic plate 18, the through hole 20 is aligned with the circular groove 21. Through the elastic force of the elastic element 23, the sliding column 22 is inserted into the through hole 20 and the connecting column 19 is lifted, thereby fixing the connecting plate 3. This avoids the fixing column 10 affecting the limiting plate 6 being inserted into the limiting groove 7. At this time, the operator inserts the limiting plate 6 into the limiting groove 7 to achieve the pre-positioning of the mold body 2, so that the fixing column 10 is aligned with the fixing hole 8. Then, the operator presses the telescopic plate 18. The connecting column 19 pushes the sliding cylinder 22 out of the through hole 20. At this time, the elastic force of the spring 17 can drive the connecting plate 3 to move towards the mold body 2, so that the fixing column 10 can be firmly locked in the fixing hole 8, thereby quickly locking the mold body 2 and firmly fixing the mold body 2 on the mounting plate 1.

[0041] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary; within the framework of this invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of this invention as described above, which are not provided in the details for the sake of brevity.

Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
