Description

Technical Field

[0001] This utility model relates to the technical field of intermediate mold resetting equipment, specifically to an intermediate mold resetting tooling. Background Technology

[0002] In modern manufacturing, the production efficiency and quality of parts are core elements of corporate competitiveness. To improve production efficiency, companies widely adopt automated production lines, in which mold processing is an indispensable link. Through carefully designed molds, rapid prototyping and mass production of parts can be achieved. However, in actual production processes, the use of molds faces several technical challenges.

[0003] Molds themselves have a certain weight, especially in the machining of large parts, where the weight is even more significant. Driven by an electric telescopic rod, the mold needs to frequently open and close. The electric telescopic rod controls the opening and closing of the mold through its telescopic movement, and its accuracy and stability directly affect the mold's working performance. However, with prolonged use, the electric telescopic rod may experience slight deviations in its displacement distance due to wear, aging, or external environmental factors. In the field of precision machining, such minute deviations can have serious consequences.

[0004] When the mold's opening and closing displacement distances shift, the relative positions of the various parts of the mold, including the middle mold, upper mold, and lower mold, also change. This can affect the product's accuracy when the mold closes. Therefore, real-time monitoring of the mold's displacement during the opening and closing process is crucial.

[0005] To address the aforementioned issues, there is an urgent need for innovative design based on the existing reset fixture. Utility Model Content

[0006] This utility model addresses the problem that existing technical solutions are too simplistic by providing a solution for a mid-mold resetting tool that is significantly different from existing technologies, thereby resolving the issues raised in the background section.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a middle mold resetting fixture, including a worktable, a mounting frame connected to the top of the worktable, a lower mold platform mounted below the mounting frame on the top of the worktable, and a hydraulic mechanism mounted on the top of the mounting frame. The end of the hydraulic mechanism passes through the mounting frame and is connected to a middle mold mounting platform for cooperating with the lower mold platform. The two sides of the middle mold mounting platform are connected to the support column of the mounting frame through sliding sleeves. A positioning structure is provided between the mounting frame, the sliding sleeves and the worktable, and the positioning structure is electrically connected to a control mechanism. The control mechanism is electrically connected to the lower mold platform and the middle mold mounting platform.

[0008] Preferably, the positioning structure includes a height adjustment part and a reset detection part. The height adjustment part includes a rotating cylinder, a connecting rod, and a bearing plate. Several rotating cylinders are connected to the top of the workbench and the top of the mounting frame. Each rotating cylinder is provided with a connecting rod, and the end of the connecting rod passes through the rotating cylinder and connects to the bearing plate.

[0009] Preferably, the rotating drum and the connecting rod are threaded together, and the rotating drum and the top of the mounting bracket are rotatably connected, and the rotating drum is distributed at equal angles with respect to the bottom of the bearing plate.

[0010] Preferably, the reset detection unit includes a mounting block, a sensor, a trigger plate, a magnetic block, a magnetic column, a cylinder, a support groove, a sliding groove, a reset spring, and a trigger rod. The top of the support plate is connected to the mounting block, and a sensor is installed on one side of the top of the mounting block. The sensor is electrically connected to the control mechanism. The outer wall of the sliding sleeve is connected to a trigger plate for sensing the sensor. A magnetic block is connected below the trigger plate, and a magnetic column is located directly below the magnetic block. The lower end of the magnetic column is located inside the cylinder, and the cylinder is installed on the other side of the top of the mounting block. The mounting block has a support groove and a sliding groove, and the two ends of the support groove are connected to the cylinder and the sliding groove, respectively. A reset spring is connected inside the sliding groove, and one end of the reset spring is connected to the trigger rod. The other end of the trigger rod passes through the outer wall of the mounting block to press the corresponding trigger button on the control mechanism.

[0011] Preferably, the magnetic block and the magnetic column have the same magnetism, and the magnetic column and the cylinder body are in a sealed, snap-fit ​​sliding connection.

[0012] Preferably, the trigger rod is configured with a "T" shaped structure, and the trigger rod and the slide groove are connected by a snap-fit ​​sliding connection.

[0013] Compared with existing technologies, the beneficial effects of this utility model are as follows: This intermediate mold reset fixture, through the setting of the positioning structure and control mechanism, enables the device to accurately detect whether the movement of the intermediate mold has been reset during the mold opening and closing process, ensuring that it is always in the correct position, thereby guaranteeing the accuracy of mold operation. Specifically, the trigger plate connected to the intermediate mold mounting platform works in conjunction with the sensor to monitor the displacement distance during mold closing in real time. For example, if the intermediate mold mounting platform fails to move to the predetermined position after mold closing, a deviation will occur. At this time, the distance between the trigger plate and the sensor will also change accordingly, and the sensor will send a signal to the control mechanism to stop the operation of the equipment, thereby avoiding further errors or damage.

[0014] In addition, this device is equipped with extra parts such as magnetic blocks, magnetic pillars, and cylinders, achieving dual protection of electronic and physical detection. This dual detection mechanism not only improves the accuracy of the mid-mold reset detection, but also ensures that even in extreme environmental conditions, such as excessively cold or hot environments, the physical detection method of magnetic blocks and magnetic pillars remains stable and reliable even if the sensor malfunctions due to environmental influences, resulting in incorrect detection results. When the data obtained from electronic and physical detection are inconsistent, the control mechanism will promptly issue a prompt signal to remind maintenance and testing, ensuring the normal operation of the equipment and the stability of product quality.

Several rotating cylinders 701 are connected to the top of the workbench 1 and the top of the mounting frame 2. Each rotating cylinder 701 is provided with a connecting rod 702, and the end of the connecting rod 702 passes through the rotating cylinder 701 and connects to the bearing plate 703.

[0023] The rotating drum 701 and the connecting rod 702 are threaded together, and the rotating drum 701 and the top of the mounting bracket 2 are rotatably connected. The rotating drum 701 is distributed at equal angles with respect to the bottom of the bearing plate 703.

The mounting block 704 is connected to the top of the support plate 703, and the sensor 705 is mounted on one side of the top of the mounting block 704. The sensor 705 is electrically connected to the control mechanism 8. The outer wall of the sliding sleeve 6 is connected to the trigger plate 706 for sensing by the sensor 705, and the magnet 707 is connected below the trigger plate 706. A magnetic post 708 is located directly below block 707.

The two detection effects of electronic and material make this device adaptable to working in various environments and ensure the stability of the detection results. This is the working principle of the middle mold reset fixture.
