Utility Model Content

[0004] This utility model relates to a demolding mechanism for an integrated mold for assembling automotive gear shift lever injection molding inserts. It solves the problems of existing devices being unable to achieve demolding simultaneously through multiple demolding structures, resulting in low demolding efficiency; and existing devices having a demolding structure without a limit on the number of positions during disassembly and assembly, resulting in low disassembly and assembly efficiency.

[0005] This utility model provides a demolding mechanism for an integrated mold for assembling an injection-molded insert of a car gear shift lever, specifically including: a mold base; a demolding rod that slides on the mold base, the demolding rod having a stepped shaft structure, one right end of the demolding rod being flush with the inner wall of the mold groove on the mold base, and a seat body welded to one left end of the demolding rod, with a helical spring sleeved on the demolding rod, one right end of the helical spring contacting the mold base, and one left end of the helical spring contacting the seat body.

[0006] Furthermore, a fixing seat is fixed on the mold base by two fixing screws, and the fixing seat is also snapped into the mold base. When the fixing seat is snapped into the mold base, the fixing screws are aligned with the threaded grooves on the mold base.

[0007] Furthermore, a hydraulic cylinder is fixed to the right end face of the fixed base. The hydraulic cylinder is driven by an external hydraulic pump. The hydraulic cylinder is aligned with the base body and acts as a rightward driving component for the base body.

[0008] Furthermore, the front and rear faces of the mold base are provided with slots at equal intervals, and the slots are semi-cylindrical groove structures; two auxiliary screws are threadedly connected to the base body, and one end of the inner side of the two auxiliary screws is respectively engaged with the slots on the front and rear faces of the mold base.

[0009] Furthermore, each of the auxiliary screws is welded with a handle, which serves as an adjustment component for the auxiliary screw.

[0010] Furthermore, each handle is threaded with a locking screw, and the inner ends of the two locking screws abut against the front and rear faces of the mold base, respectively. The demolding rod, base, helical spring, fixed base, fixed screw, hydraulic cylinder, auxiliary screw, handle and locking screw together constitute the demolding assembly.

[0011] Furthermore, the inner sides of both auxiliary screws are polished, and after polishing, one end of the inner side of both auxiliary screws is an arc-shaped structure.

[0012] Furthermore, two vibrators are symmetrically installed on the mold base. Both vibrators are electrically connected to an external control switch and an external power supply. The two vibrators are model: Wacker Neuson ARFU26.

[0013] This utility model provides a demolding mechanism for an integrated mold assembly of automotive gear shift lever inserts, which has the following advantages: From the perspective of the installation of the fixed base, this application uses a dual fixing method of snap-fit ​​and fixing screw, which not only ensures the stability of the fixed base after installation and avoids the problem of loosening and displacement during use, but also eliminates the need to repeatedly align the installation position, greatly improving the installation and fixing efficiency of the fixed base and laying a stable foundation for subsequent demolding operations.

[0014] In this application, during the demolding action, a hydraulic cylinder drives the demolding rod to move and complete the demolding. After demolding, a helical spring drives the demolding rod to automatically reset, achieving highly efficient automation of the demolding process, reducing manual intervention, and improving overall demolding efficiency. At the same time, during the movement of the demolding rod, the auxiliary screw continuously engages with the slot to generate vibration. Combined with the symmetrically installed Wacker Neuson ARFU26 vibrators on the mold base, the dual vibration action can effectively assist demolding, further improving demolding efficiency and avoiding the insertion of inserts to the inner wall of the mold groove, which would cause demolding difficulties.

[0015] In terms of adjustability and maintenance, this application allows for flexible adjustment of the vibration amplitude by rotating the handle to meet different demolding requirements. The inner side of the auxiliary screw is polished into an arc structure, which reduces wear when in contact with the slot and reduces maintenance costs. In addition, locking the screw can prevent the auxiliary screw from loosening and ensure stable vibration demolding effect. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Example 1: Please refer to Figures 1 to 5 : This utility model proposes a demolding mechanism for an integrated injection molding insert assembly of an automotive gear shift lever, comprising: a mold base 1; a demolding rod 201 sliding on the mold base 1, the demolding rod 201 having a stepped shaft structure, one right end of the demolding rod 201 being flush with the inner wall of the mold groove on the mold base 1, a seat body 202 welded to one left end of the demolding rod 201, and a helical spring 203 sleeved on the demolding rod 201, one right end of the helical spring 203 contacting the mold base 1, and one left end of the helical spring 203 contacting the seat body 202.

[0022] The mold base 1 is fixed with a fixing seat 204 by two fixing screws 205. The fixing seat 204 is also snapped into the mold base 1. After the fixing seat 204 is snapped into the mold base 1, the fixing screws 205 are aligned with the threaded grooves on the mold base 1. When installing the fixing seat 204, the fixing seat 204 is snapped into the mold base 1 and then fixed by the fixing screws 205. On the one hand, the stability of the fixing seat 204 is ensured, and on the other hand, the fixing efficiency of the fixing seat 204 is improved.

[0023] A hydraulic cylinder 206 is fixed to the right end face of the fixed base 204. The hydraulic cylinder 206 is driven by an external hydraulic pump. The hydraulic cylinder 206 is aligned with the base 202 and is the rightward driving component of the base 202. During demolding, the hydraulic cylinder 206 is driven to extend, and the hydraulic cylinder 206 drives the base 202 and the demolding rod 201 to move to the right to complete the demolding action. After demolding, the hydraulic cylinder 206 is driven to retract, and the demolding rod 201 automatically returns to its original position under the action of the helical spring 203.

[0024] The mold base 1 has slots 101 equidistantly spaced on both the front and rear faces. The slots 101 are semi-cylindrical groove structures. Two auxiliary screws 207 are threaded onto the base 202. The inner ends of the two auxiliary screws 207 are respectively engaged with the slots 101 on the front and rear faces of the mold base 1. When the demolding rod 201 moves to the right to demold, the continuous engagement of the auxiliary screws 207 with the slots 101 generates vibration, which assists in demolding and improves demolding efficiency.

[0025] Each auxiliary screw 207 is welded with a handle 208, which is an adjustment component of the auxiliary screw 207. By rotating the handle 208, the auxiliary screw 207 can be adjusted, thus achieving the adjustment of the vibration amplitude, which is highly adjustable.

[0026] Each handle 208 is threaded with a locking screw 209. The inner ends of the two locking screws 209 are respectively pressed against the front and rear faces of the mold base 1. The demolding rod 201, the base 202, the helical spring 203, the fixed base 204, the fixed screw 205, the hydraulic cylinder 206, the auxiliary screw 207, the handle 208 and the locking screw 209 together form the demolding assembly 2. During use, tightening the locking screw 209 can prevent the auxiliary screw 207 from loosening and ensure the vibration demolding effect.

[0027] The inner sides of both auxiliary screws 207 are polished. After polishing, one end of the inner side of both auxiliary screws 207 is arc-shaped. During use, this can reduce the wear of the auxiliary screws 207 and the slots 101, and reduce maintenance costs.

[0028] Example 2, based on Example 1, such as Figures 1 to 5As shown, two vibrators 3 are symmetrically installed on the mold base 1. Both vibrators 3 are electrically connected to the control switch and external power supply of the external device. The two vibrators 3 are model: Wacker Neuson ARFU26. When demolding, the two vibrators 3 are activated, and the vibration of the vibrators 3 can achieve demolding assistance.

[0029] The working principle of this embodiment is as follows: First, the fixing seat 204 needs to be snapped onto the mold seat 1, ensuring that the fixing screw 205 is aligned with the threaded groove on the mold seat 1 after the fixing seat 204 is snapped onto the mold seat 1. Then, the fixing screw 205 is used to fix the fixing seat 204 onto the mold seat 1, completing the installation and fixing of the fixing seat 204 in the demolding assembly 2. After that, according to the demolding requirements, the auxiliary screw 207 is adjusted by rotating the handle 208 to adjust the vibration amplitude. After adjustment, the locking screw 209 on the handle 208 is tightened so that one end of the locking screw 209 abuts against the front or rear face of the mold seat 1 to prevent the auxiliary screw 207 from loosening. When demolding is required, the two vibrators 3 of model ARFU26 symmetrically installed on the mold seat 1 are first started, and then the hydraulic cylinder 2 fixed on the right end face of the fixing seat 204 is driven by the external hydraulic pump. 06. The hydraulic cylinder 206 extends, driving the seat 202 aligned with it and the demolding rod 201 welded to the seat 202 to move to the right. The right end of the demolding rod 201 is flush with the inner wall of the mold groove on the mold base 1. During the movement of the demolding rod 201 to the right, the inner sides of the two auxiliary screws 207 threaded on the seat 202 are ground into an arc structure and continuously engage with the semi-cylindrical groove 101 opened on the front and rear faces of the mold base 1 to generate vibration. This vibration, combined with the vibration of the vibrator 3, assists in demolding and improves demolding efficiency. After demolding is completed, the hydraulic cylinder 206 is driven to retract by the external hydraulic pump. Under the action of the helical spring 203 sleeved on the demolding rod 201, the right end of which contacts the mold base 1 and the left end of which contacts the seat 202, the demolding rod 201 and the seat 202 automatically reset. Then, the vibrator 3 is turned off to complete one demolding operation.
