Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment technology for injection molding machines, and in particular to a balancing support device for a moving template of an injection molding machine. Background Technology

[0002] In injection molding, the moving platen is a crucial component of the mold, and its smooth operation and precise positioning directly affect the quality of the final product. Especially for large and heavy molds, the moving platen may sag or tilt due to gravity during movement and clamping. This not only accelerates wear on the guide rails but also prevents the mold from closing precisely, resulting in defects such as flash and dimensional deviations.

[0003] To address this issue, auxiliary support devices are typically installed below the moving mold. Existing support devices are mostly simple rollers or fixed-height support blocks. While they provide some support, their function is limited and their adaptability is weak. When changing to molds of different sizes or weights, these support devices often require tedious readjustment or even replacement, reducing production changeover efficiency.

[0004] Furthermore, some adjustable support devices typically employ a rigid contact clamping mechanism when locking the template in place. The operator applies a rigid clamping force directly to the template using a screw or other mechanical structure. The drawback of this locking method is that the clamping force relies entirely on the operator's experience and is difficult to control precisely. Insufficient force cannot guarantee secure support, while excessive force will create excessive stress concentration in localized areas of the template, leading to deformation or damage over time and posing a safety hazard to production.

[0005] Therefore, this utility model proposes a moving template balancing support device for injection molding machines to overcome the shortcomings of the prior art. Summary of the Invention

[0006] In view of the problems existing in the injection molding machine moving template balancing support device, such as the single structure, difficulty in adapting to different template models, and the rigid contact used during clamping and locking, which is prone to damaging the template due to excessive clamping force, this utility model aims to provide an injection molding machine moving template balancing support device with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a moving template balancing support device for an injection molding machine, comprising: a fixed plate, and a support arm telescopically connected to the fixed plate, the support arm being composed of support rods and support tubes that are sleeved together; and a locking mechanism for driving the fixed plate to move and locking.

[0008] The locking mechanism includes a support plate, on which a slide rail is fixedly connected, and a threaded rod and a through-hole are rotatably connected.

[0009] Furthermore, the fixing plate is slidably connected to the slide rail through a sliding groove and threadedly connected to the threaded rod; at the same time, a connecting rod passing through the limiting hole is fixedly connected to the fixing plate, and a second spring is sleeved on the connecting rod. The two ends of the second spring abut against the inner wall of the limiting hole and the limiting block fixed to the end of the connecting rod, respectively, forming a complete buffer locking structure.

[0010] Preferably, a telescopic plate is slidably connected to the inner wall of the fixed plate. A pull ring is fixedly connected to the telescopic plate, and a locking groove is provided for engaging with the top end of the support rod. Correspondingly, a bearing hole is provided on the fixed plate for the support rod to pass through, so as to realize the rapid adjustment of the support height.

[0011] Preferably, the support plate has a support groove for mounting the limiting shaft of the support arm and for providing structural space for the support tube to rotate around the limiting shaft.

[0012] Preferably, the bottom end of the support rod is provided with a telescopic locking assembly, which includes a latch and a ball that can extend radially out of the outer wall of the support rod, and a spring for driving the latch and ball to reset, so as to achieve self-locking of the support arm length.

[0013] Furthermore, the telescopic locking assembly also includes a connecting plate fixed inside the support rod, a compression tube slidably connected to the connecting plate, a compression column slidably inside the compression tube, and a connecting block connected between the compression column and the card and ball, with one spring connected between the compression column and the compression tube.

[0014] In one specific implementation, when the card and ball are pressed inward, the card and ball compress the spring through the connecting block and the squeezing column, thereby causing the card and ball to retract into the support rod to release the lock. After release, the elastic force of the spring pushes the components in the opposite direction to extend the card and ball to achieve locking.

[0015] Preferably, when the rotating handle of the locking mechanism is rotated to drive the threaded rod to rotate, the fixing plate can be driven to move linearly along the slide rail, and then the spring II is compressed through the connecting rod, thereby providing effective buffering force for clamping the template and preventing damage.

[0016] This utility model has the following beneficial effects: 1. This utility model solves the problem that existing support devices are mostly rigid clamping devices, which are prone to damaging the template due to excessive clamping force. It achieves the technical effect of providing a firm lock while effectively buffering the clamping force, thereby protecting the template and improving operational safety.

[0017] This utility model solves the problem in the prior art where the length of the support device is fixed or inconvenient to adjust, resulting in its inability to adapt to different template models and poor versatility. By designing a telescopic support arm with an internal spring clip and ball locking assembly, it achieves the technical effect of being able to quickly and conveniently adjust the support length and realize reliable self-locking, greatly enhancing the practicality and adaptability of the device.

[0018] This invention solves the problems of difficult height adjustment and inaccurate positioning of the support device in the prior art by adding a telescopic plate that can slide on the fixed plate and be positioned by the locking groove. It achieves the ability to quickly adjust and position the reference height of the support arm, and further improves the flexibility and convenience of the device in dealing with complex working conditions.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in 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 a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0022] Example: Please refer to Figures 1 to 4 This utility model provides a moving template balancing support device for injection molding machines, which aims to solve the problems of existing support devices, which are usually simple in structure, difficult to adapt to different template models, and are prone to damage to the template due to excessive clamping force when clamping and locking.

[0023] like Figure 1 As shown, a moving template balancing support device for an injection molding machine includes a fixed plate 1 and a support arm that is telescopically and rotatably connected to the fixed plate 1. The fixed plate 1 serves as a base component for connecting the device to external equipment and provides a reference for adjusting the support arm. The support arm provides a variable length support function to adapt to different working conditions.

[0024] To solve the above-mentioned technical problems, the technical solution of this embodiment is that a moving template balancing support device for an injection molding machine further includes a locking mechanism 2, and the locking mechanism 2 and the aforementioned fixed plate 1 form a specific structural fit and connection relationship to achieve clamping and locking with buffering function.

[0025] Please refer to Figure 1 , Figure 2 and Figure 4 The structure will be described in detail below: The locking mechanism 2 includes a support plate 201 that serves as a mounting base. A slide rail 204 is fixedly connected to the support plate 201, and a through limiting hole 203 is also provided on the support plate 201. The fixed plate 1 is slidably connected to the slide rail 204 through a sliding groove 4 provided thereon, so that it can perform linear reciprocating motion on the support plate 201.

[0026] A threaded rod 208 is rotatably connected to the support plate 201. A rotating handle 209 for easy operation is fixedly connected to the end of the threaded rod 208, and the threaded rod 208 forms a threaded connection with the fixed plate 1. At the same time, a connecting rod 205 is fixedly connected to the fixed plate 1. The connecting rod 205 passes through the limiting hole 203 of the support plate 201. The part of the connecting rod 205 located in the limiting hole 203 is fitted with a second spring 206, and the end of the connecting rod 205 is fixedly connected to a limiting block 207. The two ends of the second spring 206 abut against the inner wall of the limiting hole 203 and the limiting block 207, respectively. This structural combination allows the fixed plate 1 to be moved by rotating the rotating handle 209, thereby compressing the second spring 206 through the connecting rod 205, thus generating a flexible buffer clamping force.

[0027] Based on the above embodiments, the present invention may further include the following preferred technical solutions: As a preferred embodiment, in order to achieve convenient adjustment of the support height, a telescopic plate 5 is slidably connected to the inner wall of the fixed plate 1, a pull ring 7 is fixedly connected to the telescopic plate 5, a locking groove 6 is provided on the telescopic plate 5, and a bearing hole 3 is correspondingly provided on the fixed plate 1. The top end of the support rod 8 in the support arm can pass through the bearing hole 3 and be locked and fixed with the locking groove 6.

[0028] In a preferred embodiment, a support groove 202 is provided on the support plate 201 to provide a structural basis for the rotation of the support arm. The support groove 202 is used to install the limiting shaft 10 and to provide the necessary space for the support tube 9 in the support arm to rotate around the limiting shaft 10.

[0029] In a preferred embodiment, to achieve self-locking adjustment of the support arm length, a telescopic locking assembly is provided at the bottom end of the support rod 8. The assembly includes a clip and ball 11 that can extend radially out of the support rod 8, and a spring 14 for providing a reset force.

[0030] For a more specific implementation method, please refer to Figure 3 The telescopic locking assembly also includes a connecting plate 16 fixed inside the support rod 8. A compression tube 15 is slidably connected to the connecting plate 16. A compression column 13 is slidably connected inside the compression tube 15. The compression column 13 is connected to the card and ball 11 through a connecting block 12. A spring 14 is disposed between the compression column 13 and the compression tube 15. By pressing the card and ball 11 inward, the spring 14 can be compressed through the connecting block 12 and the compression column 13, causing the card and ball 11 to retract into the support rod 8 to release the lock. After being released, the spring 14 rebounds and pushes the card and ball 11 out to achieve automatic locking.

[0031] Working principle: When the device is working normally, first pull the pull ring 7 to make the telescopic plate 5 move up and down on the inner wall of the fixed plate 1. Then, the support rod 8 and the support tube 9 rotate together around the limiting shaft 10 until the top of the support rod 8 is fixedly engaged with the locking groove 6 through the bearing hole 3. At the same time, the clip and ball 11 at the bottom of the support rod 8 can be squeezed first, so that the clip and ball 11 drive the connecting block 12 to move towards the connecting plate 16, and then squeeze the extrusion column 13 to compress the spring 14 on the inner wall of the extrusion tube 15. When the clip and ball 11 are fully inserted into the inner wall of the support tube 9, the support rod 8 can be freely extended and retracted. When the appropriate length is reached, the spring 14 rebounds and drives the clip and ball 11 to move outward. Finally, the extension and locking of the support rod 8 and the support tube 9 are completed, and the extension plate 5 is extended to the fixed plate 1. It can be adapted to various types of templates and improves the practicality of the device. The locking mechanism 2 is used to fix and lock the template. First, rotate the rotating handle 209, which drives the threaded rod 208 to rotate on the inner wall of the support plate 201. This causes the fixing plate 1, which is fixedly connected to it, to slide centripetally on the slide rail 204 through the sliding groove 4. The fixing plate 1 also drives the connecting rod 205 to move together, so that the connecting rod 205 and the limiting block 207 slide in the limiting hole 203 and compress the second spring 206, preventing the template from being clamped too tightly and thus damaging the template. At the same time, the support groove 202 is used to fix the limiting shaft 10 and provide space for the rotation of the support tube 9. Finally, the fixing plate 1 is used to fix and support the template, which improves the practicality of the device.
