Description

Technical Field

[0001] This utility model relates to the field of mold fixing technology, specifically a mold locking device. Background Technology

[0002] In the field of mold application, mold locking devices play a crucial role. Molds, as tools used in industrial production for injection molding, die casting, stamping, extrusion and other processing technologies to manufacture products or parts of specific shapes, are directly related to product quality and production efficiency. Mold locking devices are the key to ensuring that molds maintain a stable position and prevent movement or loosening during the production process.

[0003] While some locking devices can lock molds, the cumbersome locking process greatly affects the locking speed and reduces work efficiency. Some mold locking devices have limitations in their application range, and cannot effectively fix molds with different groove orientations on the outer wall, making it difficult to meet diverse production needs.

[0004] In view of this, we propose a mold locking device. Utility Model Content

[0005] The purpose of this invention is to provide a mold locking device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A mold locking device includes a bracket, a self-locking caster wheel at the bottom of the bracket, a U-shaped frame fixedly mounted on the top of the bracket, and a movable component on the U-shaped frame. The movable component includes:

[0008] A central frame is fixedly installed inside the U-shaped frame. The top of the central frame is fixedly connected to the bottom fixed end of the hydraulic cylinder, and the top of the piston end of the hydraulic cylinder is fixedly connected to the bottom center of the storage tray.

[0009] An asynchronous motor is fixedly installed on the outer wall of the U-shaped frame. A bidirectional threaded rod is fixedly installed at the output end of the asynchronous motor. Both ends of the bidirectional threaded rod are rotatably installed on the inner wall of the U-shaped frame through bearing components. Threaded blocks are threadedly engaged on the bidirectional threaded rod.

[0010] A top block is fixedly installed on the top of the threaded block. An asynchronous motor is fixedly installed on the outer wall of the top block. A rotating plate is fixedly installed on the output end of the asynchronous motor. A first V-shaped frame is fixedly installed on the outer wall of one end of the rotating plate. A first roller is rotatably installed on the first V-shaped frame. Two sets of the threaded block, top block, asynchronous motor, rotating plate, and first V-shaped frame are arranged. Both sets of the threaded block, top block, asynchronous motor, rotating plate, and first V-shaped frame are mirror images of each other at both ends of the central frame, with the vertical centerline of the central frame as the mirror axis.

[0011] In a further embodiment, multiple sets of self-locking casters are provided, allowing the device body to move more easily.

[0012] In a further embodiment, the mold body is placed on the tray.

[0013] In a further embodiment, multiple sets of first rollers are provided on the first V-shaped frame of a single unit, which can effectively fix and lock more types of molds, thereby improving the practicality of the device body.

[0014] In a further embodiment, the rotating plate is provided with an auxiliary component, which includes a hydraulic rod. The fixed end of the hydraulic rod is fixedly connected to the inner wall of the other end of the rotating plate. A second V-shaped frame is fixedly installed on the piston end of the hydraulic rod, and a second roller is rotatably installed on the second V-shaped frame.

[0015] In a further embodiment, two sets of the hydraulic rod and the second V-shaped frame are provided.

[0016] In a further embodiment, multiple sets of second rollers are provided on the second V-shaped frame of a single unit, which can effectively fix and lock more types of molds, improving the practicality of the device body.

[0017] Compared with the prior art, the present invention provides a mold locking device, which has the following advantages:

[0018] 1. This mold locking device, in order to better fix various types of molds, is equipped with a moving component. When the hydraulic cylinder on the central frame is activated, the placement tray can move up and down, thereby driving the molds placed on the placement tray to move synchronously to accommodate molds of different heights. When the asynchronous motor is activated, the bidirectional threaded rod rotates, causing the two sets of threaded blocks to drive the top block to move towards each other. When the asynchronous motor is activated, the rotating plate drives the first V-shaped frame and the second roller to rotate. Thus, when the two sets of first V-shaped frames approach each other, more types of molds can be well fixed and locked, improving the practicality of the device body.

[0019] 2. In order to improve the locking and fixing effect of the mold, the mold locking device is equipped with an auxiliary component. When the hydraulic rod is activated, the second V-shaped frame can move, thereby driving the second roller to move synchronously. This changes the distance between the first V-shaped frame and the second V-shaped frame, which can better lock and fix molds of different sizes, improve applicability, and improve the locking and fixing effect of the mold.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

Those skilled in the art can understand the specific meaning of these terms in this application according to the specific circumstances.

[0029] Please see Figures 1-3This utility model provides a technical solution:

[0030] A mold locking device includes a bracket 1, with self-locking casters 2 at the bottom of the bracket 1. In addition, three sets of self-locking casters 2 are provided to enable the device body to move better. After reaching the designated position, the device is self-locked by the braking mechanism on the self-locking casters 2, ensuring that the device remains stable during the mold fixing process and avoiding the impact of device movement on the mold fixing effect. A U-shaped frame 3 is fixedly installed on the top of the bracket 1.

[0031] In one embodiment of this utility model, a moving component 4 is provided on the U-shaped frame 3. The moving component 4 includes a central frame 41, which is fixedly installed at the center inside the U-shaped frame 3. The top of the central frame 41 is fixedly connected to the bottom fixed end of the hydraulic cylinder 42, and the top of the piston end of the hydraulic cylinder 42 is fixedly connected to the bottom center of the placement tray 43. In addition, the mold body is placed on the placement tray 43. An asynchronous motor 44 is fixedly installed on the outer wall of the U-shaped frame 3. A bidirectional threaded rod 45 is fixedly installed at the output end of the asynchronous motor 44. The two ends of the bidirectional threaded rod 45 are rotatably installed on the inner wall of the U-shaped frame 3 through bearing components. A threaded block 46 is threadedly engaged on the bidirectional threaded rod 45. A top block 47 is fixedly installed on the top of the threaded block 46, and the outer wall of the top block 47 is fixed. An asynchronous motor 48 is installed, and a rotating plate 49 is fixedly installed at the output end of the asynchronous motor 48. A first V-shaped frame 410 is fixedly installed on the outer wall of one end of the rotating plate 49. A first roller 411 is rotatably installed on the first V-shaped frame 410. Two sets of threaded blocks 46, top blocks 47, asynchronous motor 48, rotating plate 49 and first V-shaped frames 410 are provided. The two sets of threaded blocks 46, top blocks 47, asynchronous motor 48, rotating plate 49 and first V-shaped frames 410 are mirror images of the vertical center line of the central frame 41 at both ends of the central frame 41. In addition, two sets of first rollers 411 are provided on each set of first V-shaped frames 410, which can better fix and lock more types of molds and improve the practicality of the device body.

[0032] In this embodiment, when the mold is placed on the placement tray 43, if there is a difference between the center height of the mold and the height of the top block 47, the hydraulic cylinder 42 on the center frame 41 is activated. The working principle of the hydraulic cylinder 42 is based on hydraulic transmission, and the piston end drives the placement tray 43 to move up and down vertically. Since the mold is placed on the placement tray 43, it will move synchronously, thereby adjusting the height of the mold to accommodate molds of different heights. After the height adjustment is completed, the asynchronous motor 44 is activated. The output end of the asynchronous motor 44 drives the bidirectional threaded rod 45 to rotate. The two ends of the bidirectional threaded rod 45 are rotatably mounted on the inner wall of the U-shaped frame 3 through bearing components. The threads at both ends of the rod have opposite directions. The two sets of threaded blocks 46 that are threadedly engaged with the bidirectional threaded rod 45 will move towards each other along the bidirectional threaded rod 45 under the threaded transmission. The top block 47, which is fixedly installed, also moves towards each other, thereby initially positioning the mold in the horizontal direction. Before the top block 47 completes the initial horizontal positioning, when it is necessary to adapt to molds with different outer wall types, the outer walls of different molds present grooves with different directions. First, start the asynchronous motor 48 on the outer wall of the top block 47. Its output end drives the rotating plate 49 to rotate. The first V-shaped frame 410 fixedly installed on the outer wall of one end of the rotating plate 49 and the first roller 411 rotatably installed on it will also rotate. When the two sets of first V-shaped frames 410 approach each other, the V-shaped structure of the first V-shaped frame 410 and the first roller 411 can contact the groove on the surface of the mold. In this way, by adjusting the angle and position of the first V-shaped frame 410, more types of molds can be fitted, fixed and locked, improving the adaptability of the device to molds of different shapes and improving work efficiency.

[0033] In one embodiment of this utility model, an auxiliary component 5 is provided on the rotating plate 49. The auxiliary component 5 includes a hydraulic rod 51. The fixed end of the hydraulic rod 51 is fixedly connected to the inner wall of the other end of the rotating plate 49. A second V-shaped frame 52 is fixedly installed on the piston end of the hydraulic rod 51. A second roller 53 is rotatably installed on the second V-shaped frame 52. In addition, two sets of hydraulic rods 51 and second V-shaped frames 52 are provided. Furthermore, two sets of second rollers 53 are provided on each set of second V-shaped frames 52, which can effectively fix and lock more types of molds and improve the practicality of the device body.

[0034] In this embodiment, before the moving component 4 completes the initial fixation of the mold, to further enhance the locking effect on molds of different sizes, the hydraulic rod 51 in the auxiliary component 5 is activated. The hydraulic rod 51 works similarly to the hydraulic cylinder 42. The second V-shaped frame 52, which is fixedly installed at the piston end of the hydraulic rod 51, moves when the hydraulic rod 51 extends or retracts. The second roller 53, which is rotatably installed on the second V-shaped frame 52, also moves synchronously. By adjusting the extension and retraction length of the hydraulic rod 51, the distance between the first V-shaped frame 410 and the second V-shaped frame 52 can be changed, allowing the device to adjust its position according to the actual size of the mold. This allows for better all-round and tight locking and fixing of molds of different sizes, further improving the applicability and locking effect of the device.

[0035] All electrical components mentioned in this application are electrically connected to the controller and 220V AC mains power. The controller is a conventional and known device that can control the hydraulic cylinder 42, asynchronous motor 44, asynchronous motor 48, and hydraulic rod 51. All standard parts used in this application can be purchased from the market. The specific connection methods of each part are all conventional methods such as riveting and welding that are mature in the prior art. The machinery, parts, and equipment are all conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, and will not be described in detail here.

[0036] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
