Description

Technical Field

[0001] This utility model relates to the field of fixture technology, and in particular to a fixture for quickly clamping grinding gates. Background Technology

[0002] In the field of mold processing, gate grinding is one of the key processes in mold manufacturing. Its processing accuracy and efficiency directly affect the final quality and production cycle of the mold. In order to ensure the stability of the mold during gate grinding and avoid processing errors caused by mold displacement, it is usually necessary to use special fixtures to fix the mold.

[0003] Most existing fixtures adopt a single clamping structure, which can only fix a single mold at a time. If multiple sets of molds need to be clamped, multiple independent clamping control components are often required. This not only increases the overall structural complexity of the fixture, but also makes the operation steps cumbersome. The operator needs to adjust each clamping component one by one, which greatly prolongs the mold clamping time and seriously restricts the improvement of processing efficiency. To solve the above problems, this application proposes a fixture for quick clamping of grinding gates. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a quick clamping fixture for grinding gates. This fixture can clamp multiple sets of molds with grinding gates without the need for multiple independent clamping control components, simplifying the overall structure and avoiding manual adjustments by operators. Multiple sets of molds can be clamped and fixed by a unified driving clamping mechanism, significantly reducing mold clamping time, effectively adapting to batch production scenarios, and significantly improving processing efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A quick clamping fixture for grinding gates includes a base. Two horizontal plates are fixedly connected to the top of the base. A vertical plate is fixedly connected to the same side end of the two horizontal plates. A fixing plate is fixedly connected to the two vertical plates. Multiple sets of molds with grinding gates are provided above the base. Two pairs of clamping plates are provided above the base. Two tension springs are fixedly connected to each pair of clamping plates. Both ends of each clamping plate are provided with inclined surfaces. Each vertical plate is provided with two clamping mechanisms. Each clamping mechanism includes a threaded rod that passes through the vertical plate and is threadedly connected to it. A handle is fixedly connected to the end of the threaded rod away from the vertical plate. A pin is fixedly connected to the end of the threaded rod away from the handle. The outer wall of the pin is arranged to abut against the outer wall of the inclined surface.

[0006] Preferably, multiple arc surfaces are provided at both ends of the fixing plate, on the side wall of each clamping plate, and on the side wall of the horizontal plate, and the inner wall of the arc surface is arranged to abut against the outer wall of the mold with the grinding gate.

[0007] Preferably, a plurality of protective pads are fixedly connected to the top of the base, and the mold with the grinding gate is arranged above the protective pads.

[0008] Preferably, the two clamping plates are provided with grooves at their opposite ends, and the two ends of the tension spring are respectively inserted into the corresponding grooves and fixedly connected to their inner walls.

[0009] Preferably, the vertical plate has a through opening, the outer wall of the threaded rod has an external thread, and the inner wall of the through opening has an internal thread that mates with the external thread.

[0010] Preferably, the insert is a frustum, and the inclined surface of the inclined surface is arranged to abut against the outer wall of the frustum.

[0011] Compared with the prior art, the advantages of this utility model are as follows: 1. The fixture can clamp multiple sets of molds with grinding gates without the need for multiple independent clamping control components, which simplifies the overall structure and avoids the need for operators to adjust and operate them one by one. Multiple sets of molds can be clamped and fixed by a unified driving clamping mechanism, which greatly reduces the time spent on mold clamping, effectively adapts to batch production scenarios, significantly improves processing efficiency, and solves the problem of low efficiency of single clamping structures in existing technologies.

[0012] 2. The fixture achieves precise positioning of the mold by setting positioning structures that are adapted to the outer wall of the mold on the fixed plate, clamping plate and horizontal plate, avoiding lateral displacement of the mold during processing and ensuring the dimensional accuracy of the grinding gate; at the same time, the protective pad on the top of the base and the adapted positioning contact surface form double protection, which can prevent indentation and wear problems caused by rigid contact between the mold and the fixture, thus protecting the appearance and accuracy of the mold and reducing the defect rate, making up for the shortcomings of the existing technology in mold positioning and protection.

[0013] 3. The clamping mechanism adopts a drive component with a handle, which can be manually operated by the operator without the need for additional tools, and the force is more even, avoiding the imbalance of force on the mold. With the coordinated design of the reset component, the reset component can automatically pull the relevant parts to reset when the mold is released, so that the mold can quickly get out of the clamping state without having to loosen the drive components one by one, simplifying the operation steps, improving the mold release efficiency, and solving the problems of cumbersome operation and low degree of automation in the existing technology.

[0014] In summary, the fixture can clamp multiple sets of molds with grinding gates without the need for multiple independent clamping control components, simplifying the overall structure and avoiding the need for operators to adjust each one individually. Multiple sets of molds can be clamped and fixed by a unified driving clamping mechanism, which greatly reduces the time spent on mold clamping, effectively adapts to batch production scenarios, and significantly improves processing efficiency.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Reference Figures 1-4 A quick clamping fixture for grinding gates includes a base 1, which provides basic support for the entire fixture. Two horizontal plates 2 are fixedly connected to the top of the base 1. The horizontal plates 2 are used to connect the base 1 and vertical plates 3, and cooperate with clamping plates 13 and fixing plates 4 to form a clamping space for a mold 5 with grinding gates. The vertical plates 3 are fixedly connected to the same side ends of the two horizontal plates 2. The vertical plates 3 provide an installation carrier for the clamping mechanism, and strengthen the overall frame strength of the fixture by connecting with the horizontal plates 2 and fixing plates 4. The two vertical plates 3 are fixedly connected to a fixing plate 4, which is fixedly connected to the base 1. The fixing plate 4, together with the horizontal plates 2 and clamping plates 13, provides lateral limit for the mold 5 with grinding gates, ensuring that the mold does not shift laterally during clamping.

[0019] Multiple sets of molds with grinding gates 5 are provided above the base 1. The molds with grinding gates 5 are the objects to be clamped by this fixture. Batch processing is achieved through multiple clamping. Two pairs of clamping plates 13 are provided above the base 1. The clamping plates 13 are adjusted in spacing under the drive of the clamping mechanism. Together with the horizontal plate 2 and the fixed plate 4, they complete the clamping and releasing action of the molds with grinding gates 5. Multiple arc surfaces 6 are provided on both ends of the fixed plate 4, on the side wall of each clamping plate 13 and on the side wall of the horizontal plate 2. The arc surfaces 6 fit against the outer wall of the molds with grinding gates 5, which not only avoids damage to the mold surface during clamping, but also improves the positioning accuracy of the mold. The inner wall of the arc surface 6 is arranged to abut against the outer wall of the molds with grinding gates 5. Multiple protective pads 7 are fixedly connected to the top of the base 1. The protective pads 7 are placed between the base 1 and the molds with grinding gates 5, which play a buffering and protective role for the bottom of the mold, preventing the mold from directly contacting the base 1 and causing wear. The molds with grinding gates 5 are arranged above the protective pads 7. Each pair of clamping plates 13 is fixedly connected to two tension springs 8. The tension springs 8 provide a restoring force through their own elastic deformation. When the clamping mechanism is released, they pull the two clamping plates 13 closer to each other, realizing the automatic mold release action of the fixture. The opposite ends of the two clamping plates 13 are provided with grooves. The grooves are used to fix the two ends of the tension springs 8, ensuring that the tension springs 8 and clamping plates 13 are firmly connected and preventing the springs from falling off during the extension and contraction process. The two ends of the tension springs 8 are respectively inserted into the corresponding grooves and fixedly connected to their inner walls. Each clamping plate 13 has inclined surfaces 9 at both ends. The inclined surfaces 9 cooperate with the outer wall of the insert post 12 to convert the axial movement of the insert post 12 into the lateral movement of the clamping plate 13, realizing the spacing adjustment of the clamping plates 13. The insert post 12 is a frustum. The inclined surface of the inclined surface 9 is arranged to abut against the outer wall of the frustum. Each vertical plate 3 is provided with two clamping mechanisms. The clamping mechanisms provide driving force for the movement of the clamping plates 13, and the clamping and fixing of the mold 5 with the grinding gate is realized through mechanical transmission. The clamping mechanism includes a threaded rod 10 that passes through and is threadedly connected to the vertical plate 3. The threaded rod 10 converts rotational motion into axial linear motion through the threaded engagement with the vertical plate 3, driving the insert 12 to move closer to or away from the inclined plane 9. A through-hole is provided on the vertical plate 3. The internal thread of the inner wall of the through-hole engages with the external thread of the threaded rod 10, providing rotational support and axial movement guidance for the threaded rod 10. The outer wall of the threaded rod 10 is provided with external threads, and the inner wall of the through-hole is provided with internal threads that engage with the external threads. A handle 11 is fixedly connected to the end of the threaded rod 10 away from the vertical plate 3. The handle 11 increases the force application point, making it easier for the operator to rotate the threaded rod 10 and reducing the difficulty of operation. The insert 12 is fixedly connected to the end of the threaded rod 10 away from the handle 11. The insert 12 contacts the inclined plane 9 and applies pressure under the drive of the threaded rod 10, pushing the clamping plate 13 to move to achieve the clamping action. The outer wall of the insert 12 is arranged to abut against the outer wall of the inclined plane 9.

[0020] In this utility model, when multiple molds with grinding gates 5 need to be clamped and fixed, the operator places the molds with grinding gates 5 between two arc surfaces 6. The bottom of the molds with grinding gates 5 can be protected by the arrangement of the protective pads 7. The operator holds multiple handles 11 and rotates them, which drives the threaded rod 10 and the insert 12 to rotate, so that the insert 12 moves towards the inclined surface 9 until the outer wall of the insert 12 abuts against the outer wall of the inclined surface 9, thereby increasing the distance between the two clamping plates 13. During this process, the tension spring 8 is stretched until the horizontal plate 2, the clamping plate 13, and the fixing plate 4 clamp and fix the multiple molds with grinding gates 5, thus completing the installation and fixing of the molds with grinding gates 5. After processing, the worker holds the handle 11 and rotates it in the opposite direction, causing the threaded rod 10 and the insert 12 to rotate in the opposite direction. This moves the insert 12, the threaded rod 10, and the handle 11 away from the mold with the grinding gate 5, so that the insert 12 is no longer pressed against the inner wall of the inclined surface 9. Under the reset action of the stretched tension spring 8, the two clamping plates 13 move closer to each other and are located between the two clamping plates 13 through the insert 12, so that the two clamping plates 13 and the insert 12 remain in contact, thereby increasing the distance between the horizontal plate 2, the clamping plate 13, and the fixed plate 4. At this time, multiple molds with grinding gates 5 can be taken out.
