Description

Technical Field

[0001] This utility model relates to the field of coilover mold technology, specifically a coilover reversing mechanism. Background Technology

[0002] The product's threaded teeth are angled, and if the threaded teeth mechanism is too large, it interferes with the mold and the injection molding machine's isolation pillar. The conventional approach is to use a larger injection molding machine, which increases costs and reduces efficiency. To address this, we have developed a threaded teeth reversing mechanism. This mechanism, through its unique design, effectively solves the interference problem caused by the angled threaded teeth, improving mold efficiency and product quality. Furthermore, the reversing mechanism's structure has been optimized, making it more compact and facilitating operation in limited spaces, reducing production costs and increasing production efficiency.

[0020] A preferred embodiment of the coilover reversing mechanism provided by this utility model is, for example... Figure 1-4The diagram shows a reversing mechanism for a sprue. This mechanism is located within a sprue mold, which includes an upper mold base 11 and a lower mold base 12 directly below it. The outer side of the sprue mold is fitted with injection molding machine isolation pillars 19.

A swivel drive mechanism 1 2 is provided on one side of the male template 14. A sliding core-pulling mechanism 1 3 is provided between one side of the male template 14 and the female template 15. A swivel drive mechanism 2 4 is also provided on the female template 15. A sliding core-pulling mechanism 2 5 is also provided between one side of the male template 14 and the female template 15.

[0021] The spool drive mechanism 2 includes a motor base 21 mounted on one side of the male template 14. A hydraulic motor 22 is mounted on the motor base 21. A sprocket 23 is fixedly connected to the output end of the hydraulic motor 22. The sprocket 23 is mounted to another sprocket 23 via a chain 24. The other sprocket 23 is mounted on a spool shaft 25. The bottom end of the spool shaft 25 passes through the male template 14 and the upper mold core, and extends into the upper mold core to fit against the inner wall of the product 20, thereby performing spooling.

[0022] Hydraulic motor 22 starts, driving sprocket 23 to rotate, which is transmitted to coilover shaft 25 via chain 24, causing it to rotate rapidly. The coilover core on coilover shaft 25 fits tightly against the inner wall of product 20, achieving precise coiling. At the same time, coilover drive mechanism 4 works in coordination with sliding core-pulling mechanisms 3 and 5 to ensure the smoothness and efficiency of the entire coiling process. This design not only guarantees the quality of the product but also improves production efficiency.

[0023] The sliding core-pulling mechanism 3 includes a cylinder mounting base 32 installed on one side of the mother template 15. A magnetic cylinder 31 is fixedly installed on the cylinder mounting base 32. A T-block 33 is fixedly connected to the output end of the magnetic cylinder 31. The function of the T-block 33 is to push the push rod 34 connected to it, thereby driving the sliding component of the sliding core-pulling mechanism 3 to move back and forth, so as to realize the core-pulling action.

[0024] A sliding seat 34 is installed on the mother template 15. The sliding seat 34 is adapted to the T-block 33 and is fitted with a braking block 35 on the outer wall of the sliding seat 34. A baffle slider 36 is installed on the inner side of the sliding seat 34.

[0025] The second coilover drive mechanism 4 includes a conversion seat 41 mounted on the mother template 15, two slider fixing plates 42, and a slider seat 43 mounted on one side of the slider fixing plates 42. A motor 44 is mounted on the conversion seat 41. The output end of the motor 44 is fixedly connected to a drive shaft 45. The other end of the drive shaft 45 passes through the conversion seat 41 and extends to the outside. A bevel gear 46 is fixedly connected to the other end of the drive shaft 45. The bevel gear 46 meshes with a bevel gear 47. A driven shaft 48 is installed in the inner hole of the bevel gear 47. A driven gear 49 is fixedly sleeved on the outer wall of the driven shaft 48. The driven gear 49 is installed in the gear seat 410. A power gear 411 meshes with the top of the driven gear 49. The driven gear 49 is installed in the slider fixing plate 42. A coilover shaft 412 is installed in the inner hole of the driven gear 49. The other end of the coilover shaft 412 extends to the inner wall of the product 20 for contact, thereby performing coilover.

[0026] After the motor 44 starts, it drives the drive shaft 45 to rotate. The meshing of bevel gear 1 46 and bevel gear 2 47 enables the driven shaft 48 to obtain power, which in turn drives the driven gear 49 and the coilover shaft 2 412 to rotate at high speed. The coilover core on the coilover shaft 2 412 is in close contact with another part of the inner wall of the product 20 to complete the fine coilover operation. This design makes the cooperation between the sliding core pulling mechanism and the coilover drive mechanism more tight, further improving production efficiency and product quality.

[0027] The sliding core-pulling mechanism 25 includes a slider seat 51, a slider fixing plate 2 54 is installed on the inner side of the slider seat 51, and a slider 55 is installed on the inner side of the slider fixing plate 2 54, which works together with the baffle slider 36. An inclined guide post 53 is provided through the slider seat 51, and a braking block 2 52 is installed on the outer wall of the slider seat 51.

[0028] After the inclined guide post 53 is pulled out and the second brake block 52 is released, the slider 55 retracts on the second slider fixing plate 54, thereby realizing the secondary core pulling action and ensuring the structural integrity and precision of the product.

[0029] During use, when the mold is closed, the injection molded product is produced. When the mold is opened, the first step is to perform thread tightening. The hydraulic motor 22 starts and drives the sprocket 23 to rotate. The rotation is transmitted to the thread tightening shaft 25 through the chain 24, causing it to rotate rapidly. The thread tightening core on the thread tightening shaft 25 fits tightly against the inner wall of the product 20 to achieve precise thread tightening. After the motor 44 starts, it drives the drive shaft 45 to rotate. The meshing of the bevel gear 46 and the bevel gear 47 gives power to the driven shaft 48, which in turn drives the driven gear 49 and the thread tightening shaft 412 to rotate at high speed. The core on the second 412 of the auger shaft is in close contact with another part of the inner wall of the product 20 to complete the fine auger operation; then the magnetic cylinder 31 is activated, which pushes the T-block 33, and the T-block 33 pushes the sliding seat 34 to pull the core outward; on the other hand, after the inclined guide post 53 is pulled out and the second brake block 52 is released, the slider 55 retracts on the second slider fixing plate 54, thereby realizing the second core pulling action, ensuring the structural integrity and precision of the product.

[0030] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any 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.
