Technical Field

[0001] This utility model relates to the field of support device technology, specifically a support device suitable for injection molds with complex shapes. Background Technology

[0002] Injection mold: a tool for producing plastic products. Molten plastic is injected into the mold cavity under high pressure by an injection molding machine. After cooling and solidification, the molded product is obtained. It is also a tool that gives plastic products a complete structure and precise dimensions. During the injection mold processing, it needs to be polished, and grinding machines are widely used.

[0003] Existing support devices for complex-shaped injection molds have been found to be in use during the injection mold production process. Traditional support devices have a fixed platform position. When the position of the injection mold needs to be raised, the fixed support device cannot raise the position of the injection mold, which reduces the production efficiency of the injection mold. Therefore, the efficiency and effectiveness of the support device are reduced, resulting in poor practicality. Utility Model Content

The lifting mechanism is used to adjust the height of the support platform.

[0008] The lifting mechanism also includes a lifting plate, a connecting plate, a rotating plate, a fixed seat, a sliding plate, and a first lead screw. The support box contains a working cavity. Multiple sets of sliding grooves are provided at the top of the support box and communicate with the working cavity. The multiple sets of connecting plates are slidably fitted with corresponding sliding grooves. The tops of the multiple sets of connecting plates are connected to the bottom of the support platform, and the bottoms of the multiple sets of connecting plates are fixedly connected to the top of the lifting plate. The left and right ends of the first lead screw are rotatably connected to the inner walls of the corresponding working cavities via bearings. A threaded through hole is provided in the middle of the sliding plate, and the first lead screw is screwed onto the sliding plate through the threaded through hole. The sliding plate is slidably connected to the inner wall of the support box via a guide mechanism. Multiple sets of fixed seats are provided at the tops of the two sets of sliding plates and at the bottom of the lifting plate. The upper and lower sides of the rotating plate are rotatably connected to the corresponding fixed seats.

[0009] Furthermore, to facilitate smooth sliding of the sliding plate, the present invention includes an improvement in the guiding mechanism, which further includes guide rods. Guide rods are symmetrically installed on the inner wall of the support box, and first through holes are provided on both sides of the sliding plate. The guide rods slide and fit with the sliding plate through the first through holes.

[0010] Furthermore, to facilitate the driving and adjustment of the first lead screw, the present invention includes a drive motor, wherein the mounting end of the drive motor is fixedly connected to the middle of the outer side of the support box, and the output end of the drive motor is fixedly connected to the first lead screw.

[0013] Furthermore, in order to facilitate the sliding of the two sets of sliding plates in opposite directions, the improvement of this utility model is that the threaded through holes between the two sets of sliding plates rotate in opposite directions.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides a support device suitable for injection molds with complex shapes, which has the following beneficial effects:

[0016] Highly efficient and flexible height adjustment: By setting up a lifting mechanism, utilizing the threaded engagement between the first lead screw and the sliding plate, as well as the linkage of components such as the rotating plate and the connecting plate, the support platform can be quickly and accurately raised and lowered, completely changing the drawbacks of the fixed platform of traditional support devices. When it is necessary to raise or lower the position of the injection mold, it can be done without complicated operations, significantly improving the efficiency of height adjustment in the injection mold production process, thereby improving the overall production efficiency.

[0017] Stable and reliable structural design: The guide rod and sliding plate in the guide mechanism are fitted together, which effectively restricts the movement direction of the sliding plate and prevents it from deviating during the rotation of the screw, thus ensuring the smoothness of the lifting process; the setting of the limit column and rubber pad plays a limiting and buffering role when the support platform and lifting plate reach the limit position, preventing damage to components due to excessive lifting, and enhancing the stability and safety of the entire support device.

[0018] High degree of automation: The drive motor configuration, especially the use of servo motors, enables automated control of the support platform's lifting and lowering. Operators only need to control the motor's start, stop, and direction to easily complete height adjustments, reducing manual operation and labor intensity. Furthermore, the high precision of servo motors allows for more accurate control of the support platform's lifting height, meeting the high-precision height adjustment requirements of complex-shaped injection molds.

[0019] Enhanced practicality: This support device effectively solves the problem that traditional support devices cannot adjust the mold height. The convenience of height adjustment, the stability of the structure, and the automated control make it more widely applicable in the production and processing of complex-shaped injection molds, greatly enhancing the efficiency and effectiveness of the support device and improving its practicality.

[0024] 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.

[0025] Please see Figure 1-3 A support device suitable for injection molds with complex shapes includes an injection mold body 1, a support platform 2, a support box 3, and a support leg 4. The top of the support platform 2 is provided with the injection mold body 1, the bottom of the support box 3 is fixedly connected to the support leg 4, and a lifting mechanism is provided inside the support box 3. The lifting mechanism is used to adjust the height of the support platform 2.

[0026] The lifting mechanism also includes a lifting plate 5, a connecting plate 6, a rotating plate 7, a fixed seat 8, a sliding plate 9, and a first lead screw 10. The support box 3 is provided with a working cavity 11. The top of the support box 3 is connected to the working cavity 11 and is provided with multiple sets of sliding grooves 12. The multiple sets of connecting plates 6 are slidably fitted with the corresponding sliding grooves 12. The top of the multiple sets of connecting plates 6 is connected to the bottom of the support platform 2, and the bottom of the multiple sets of connecting plates 6 is fixedly connected to the top of the lifting plate 5. The left and right ends of the first lead screw 10 are rotatably connected to the inner wall of the corresponding working cavity 11 through bearings. The sliding plate 9 is provided with a threaded through hole in the middle. The first lead screw 10 is screwed to the sliding plate 9 through the threaded through hole. The sliding plate 9 is slidably connected to the inner wall of the support box 3 through a guide mechanism. The top of the two sets of sliding plates 9 is provided with multiple sets of fixed seats 8. The bottom of the lifting plate 5 is provided with multiple sets of fixed seats 8. The upper and lower sides of the rotating plate 7 are rotatably connected to the corresponding fixed seats 8.

[0027] It is worth noting that the injection mold body 1, support platform 2, and support box 3 used in this invention are all existing technologies and will not be described here.

[0028] When this device is in use

[0029] Start-up preparation: When it is necessary to adjust the height of the injection mold body 1, check whether the drive motor 14, the first lead screw 10, the sliding plate 9 and other components are in normal condition, and ensure that the connection of each component is firm and there is no looseness or damage.

[0030] Height Adjustment: The operator starts the drive motor 14 via a control switch according to actual needs. Since the output end of the drive motor 14 is fixedly connected to the first lead screw 10, the drive motor 14 drives the first lead screw 10 to rotate after it starts running. Because the threaded through holes between the two sets of sliding plates 9 rotate in opposite directions, when the first lead screw 10 rotates, the two sliding plates 9 will slide in opposite directions along the guide rod 13. During the movement of the sliding plates 9, the rotating plate 7 is driven to rotate through the fixed seat 8, and the rotating plate 7 in turn pushes the lifting plate 5 to move up and down. The lifting plate 5 is connected to the support platform 2 through the connecting plate 6, thereby realizing the raising or lowering of the support platform 2 and completing the adjustment of the height of the injection mold body 1.

[0031] Limit protection: During the descent of the support platform 2, when it reaches the set limit position, the support platform 2 or the lifting plate 5 will contact the rubber pad 16 at the top of the limit post 15. The rubber pad 16 acts as a buffer, and at the same time, the limit post 15 restricts the continued movement of the support platform 2 and the lifting plate 5, preventing damage to the equipment due to excessive lifting and lowering, and ensuring the safe operation of the entire support device.

[0032] Adjustment complete: When the support platform 2 reaches the required height, the operator turns off the drive motor 14, the first lead screw 10 stops rotating, the sliding plate 9 no longer moves, and the support platform 2 stays stably at the target height. At this time, the subsequent processing operations of the injection mold can be carried out.

[0033] In actual use, it was found that the sliding plate 9 was not easy to slide smoothly. In order to solve the above problem, in this embodiment, the guiding mechanism also includes a guide rod 13. The guide rod 13 is symmetrically installed on the inner wall of the support box 3. The sliding plate 9 is provided with first through holes on both sides. The guide rod 13 slides and fits with the sliding plate 9 through the first through holes.

[0034] In actual use, it was found that it was inconvenient to drive and adjust the first lead screw 10. In order to solve the above problem, this embodiment also includes a drive motor 14. The mounting end of the drive motor 14 is fixedly connected to the middle of the outer side of the support box 3, and the output end of the drive motor 14 is fixedly connected to the first lead screw 10.

[0035] In actual use, it was found that it was not convenient to limit the sliding of the support platform 2 and the lifting plate 5. In order to solve the above problem, this embodiment also includes a limiting post 15 and a rubber pad 16. The top of the support box 3 and the bottom of the working cavity 11 are provided with limiting posts 15. The top of the limiting post 15 is fixedly connected to the rubber pad 16. The limiting post 15 is used to limit the sliding of the support platform 2 and the lifting plate 5.

[0036] In actual use, it was found that it was not convenient to improve the driving effect. In order to solve the above problem, in this embodiment, the drive motor 14 is set as a servo motor.

[0037] As a preferred embodiment of the above, the threaded through holes between the two sets of sliding plates 9 have opposite rotation directions.
