Description

Technical Field

[0001] This utility model relates to the technical field of hydraulic locking devices, specifically a hydraulic locking device for quick mold changing in injection molds. Background Technology

[0002] Injection molding, as one of the most widely used technologies in the plastics processing field, occupies a pivotal position in modern manufacturing. With the continuous development of the global economy and the constant progress of technology, the demand for plastic products in various industries has experienced explosive growth. From automotive parts to electronic product casings, from everyday household goods to medical equipment components, injection molded products are ubiquitous. This widespread application has driven the vigorous development of the injection molding industry, with the number of injection molding machines and their usage frequency constantly increasing. Mold change, as a key link in the injection molding production process, directly affects the smoothness of the entire production process and the stability of product quality.

[0003] When using a hydraulic locking device for quick mold change in injection molding, traditional hydraulic locking devices generally require manual pushing to engage with the mold locking groove, and then hydraulic locking of the mold. The traditional manual pushing method is often cumbersome, thus reducing the working efficiency of the equipment. Utility Model Content

[0004] The purpose of this utility model is to provide a hydraulic locking device for quick mold change of injection molds, so as to solve the problem that the traditional hydraulic locking device mentioned in the background art generally requires manual pushing to the mold locking groove for engagement, and then locking the mold by hydraulic means. The traditional manual pushing method is often cumbersome, thus reducing the working efficiency of the equipment.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hydraulic locking device for quick mold changing of injection molds, comprising a main base plate, wherein connecting blocks are fixedly connected to the top of the main base plate near the four corners, a fixing plate is fixedly connected between the tops of the four connecting blocks, a fixing limiting ear is fixedly connected to the top of the fixing plate near the four corners, a sliding rod is slidably arranged between the interiors of the four fixing limiting ear brackets, a movable platform is fixedly connected between the opposite ends of each pair of sliding rods, and a fixing rod is fixedly connected to the top of the two movable platforms near the front and rear edges.

[0006] In a preferred embodiment, a hydraulic locking device is fixedly provided on the top of each of the four fixing rods, and a hydraulic connection port is provided on the outer surface of each of the four hydraulic locking devices.

[0007] In a preferred embodiment, a slide rail is provided laterally at the bottom center of the fixed plate, and sliders are slidably provided on the outer surface of the slide rail near the edges on both sides.

[0008] In a preferred embodiment, a hydraulic telescopic device is fixedly installed at the top edge of the main body base plate near the front side, and an L-shaped fixing frame is fixedly connected to the output end of the hydraulic telescopic device.

[0009] In a preferred embodiment, the top of the L-shaped fixing frame is rotatably connected to a transmission rod near both sides via a short rotating rod.

[0010] In a preferred embodiment, the opposite ends of both transmission rods are connected to the slider via a rotating short rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention first activates the hydraulic telescopic device. The output end of the device extends forward, causing the L-shaped fixed frame to slide to one end. The L-shaped fixed frame is rotatably connected to the transmission rod, which in turn is rotatably connected to the slider. When the L-shaped fixed frame slides to one end, the transmission rod causes the slider to slide outwards along the outer surface of the slide rail, thus causing the movable table to slide outwards. The sliding arrangement of the fixed limiting ear and the slide rod makes the sliding of the movable table more stable. The outward sliding of the movable table causes the fixed rod and the hydraulic locking device to slide outwards, facilitating quick mold changes. Conversely, by retracting the hydraulic telescopic device inwards, the movable tables on both sides retract inwards, causing the fixed rod and the hydraulic locking device to retract inwards and engage with the mold locking groove. The hydraulic device connected through the hydraulic connection port then tightens the hydraulic locking device, improving the equipment's working efficiency. Attached Figure Description

Connecting blocks 2 are fixedly connected to the top of the main base plate 1 near the four corners. The connecting blocks 2 can fix a fixing plate 3 to the main base plate 1. A fixing plate 3 is fixedly connected between the tops of the four connecting blocks 2. A fixing limiting ear 4 is fixedly connected to the top of the fixing plate 3 near the four corners. The fixing plate 3 and the fixing limiting ear 4 can make the sliding of the slide rod 5 more stable. Slide rods 5 are slidably arranged inside the four fixing limiting ear 4. The sliding arrangement of the fixing limiting ear 4 and the slide rod 5 can make the sliding of the movable platform 6 more stable. A movable platform 6 is fixedly connected between the opposite ends of each pair of slide rods 5.

The sliding of the fixing rod 7 can drive the hydraulic locking device 8 to slide synchronously.

[0021] Hydraulic locking devices 8 are fixedly installed at the top of each of the four fixed rods 7. Hydraulic connection ports 9 are provided on the outer surfaces of the four hydraulic locking devices 8. A slide rail 10 is horizontally arranged at the bottom center of the fixed plate 3. Sliding blocks 11 are slidably installed on the outer surfaces of the slide rail 10 near the edges on both sides. A hydraulic telescopic device 12 is fixedly installed at the top of the main body base plate 1 near the front edge. An L-shaped fixing frame 13 is fixedly connected to the output end of the hydraulic telescopic device 12. A transmission rod 14 is rotatably connected to the top of the L-shaped fixing frame 13 near the edges on both sides via a rotating short rod. The opposite ends of the two transmission rods 14 are rotatably connected to the sliding blocks 11 via a rotating short rod. When the hydraulic telescopic device 12 is activated, it extends forward through the output end of the hydraulic telescopic device 12, thereby driving the L-shaped... The fixed frame 13 extends and slides to one end. It is rotatably connected to the transmission rod 14 through the L-shaped fixed frame 13, and rotatably connected to the slider 11 through the transmission rod 14. When the L-shaped fixed frame 13 extends and slides to one end, the slider 11 slides outward on the outer surface of the slide rail 10 through the transmission rod 14, thereby driving the movable table 6 to slide outward.

The L-shaped fixed frame 13 is rotatably connected to the transmission rod 14, and the transmission rod 14 is rotatably connected to the slider 11. When the L-shaped fixed frame 13 extends and slides to one end, the transmission rod 14 causes the slider 11 to slide outward on the outer surface of the slide rail 10, thereby driving the movable table 6 to slide outward. The fixed limit ear is used to control the movement. The sliding arrangement of the frame 4 and the slide bar 5 makes the sliding of the movable platform 6 more stable. The outward sliding of the movable platform 6 drives the fixed rod 7 and the hydraulic locking device 8 to slide outward, which facilitates quick mold replacement. Conversely, the inward retraction of the hydraulic telescopic device 12 can drive the movable platforms 6 on both sides to retract inward, thereby driving the fixed rod 7 and the hydraulic locking device 8 to retract inward and push them into the mold locking groove for locking. The hydraulic equipment connected through the hydraulic connection port 9 drives the hydraulic locking device 8 to tighten, improving the working efficiency of the equipment.
