Description

Technical Field

[0001] This utility model belongs to the technical field of mold fixing auxiliary support, specifically a fixing auxiliary support for hardware molds. Background Technology

[0002] Metal molds are used in industrial production to shape metal materials into parts or products of the required shape using various presses and special tools mounted on the presses. These special tools are collectively called metal molds, and metal mold fixing frames are fasteners used to fix metal molds.

[0003] A search revealed that patent publication number CN2209428563U discloses an auxiliary fixing bracket, particularly an auxiliary fixing bracket for hardware molds. This utility model provides such an auxiliary fixing bracket for hardware molds, including a support frame and a mold, with the mold slidably mounted on the support frame. By pushing a push rod backward to press the inclined panel outward and press the limiting rod upward, the limiting rod disengages from the mold, allowing the mold to be removed. This enables quick mold disassembly, facilitating mold replacement for workers.

[0004] In practical use, existing fixed auxiliary supports for hardware molds require manual centering of the hardware molds during installation and fixation. This positioning operation is cumbersome and affects the efficiency of hardware mold installation. Furthermore, the friction between the hardware mold and the fixed support is large when the hardware mold is moved during centering, making it difficult to move and further affecting the efficiency of hardware mold installation. Therefore, a fixed auxiliary support for hardware molds is designed. Utility Model Content

[0010] A second rotating shaft is installed in the bearings at both the front and rear ends of the surface of the movable plate. An L-shaped positioning clamp is installed at the top of the second rotating shaft, and an L-shaped spring plate is installed at the bottom of the second rotating shaft. A second connecting post is provided at the bottom of the L-shaped spring plate. The second connecting post is connected to the first connecting post through a tension spring.

[0014] Preferably, both the rotating plate and the movable plate are located below the support plate, a first rotating shaft is installed at the center of the upper surface of the rotating plate, and the other end of the first rotating shaft is installed in a bearing at the center of the lower surface of the support plate.

[0015] Preferably, the top end of the second rotating shaft passes through the strip-shaped slot, the L-shaped positioning clamp is located above the top plate, and the outer wall of the second rotating shaft and the wall of the strip-shaped slot are in clearance fit.

[0016] Preferably, the second hydraulic telescopic rod is installed at the rear end of the lower surface of the support plate.

[0017] Compared with existing technologies, one or more of the above technical solutions have the following beneficial effects:

[0018] 1. In this utility model, through the coordinated arrangement of structures such as the mold moving mechanism, when the worker installs and fixes the hardware mold, after the worker hoists the hardware mold to the relatively central position on the upper surface of the top plate, the worker activates the first hydraulic telescopic rod, which drives the lifting plate to move upward. After the lifting plate moves upward to a certain position, when the top of the bullseye caster passes through the first through hole on the surface of the top plate, it will lift the hardware mold on the top plate to a certain height. Then, the bottom of the hardware mold contacts the top of the bullseye caster. At this time, the hardware mold is in a state that is easy to move, thereby avoiding the situation where the hardware mold is difficult to move during the automatic center positioning process due to excessive friction between the hardware mold and the installation components, thus improving the efficiency of automatic center positioning and fixed clamping of the hardware mold.

[0019] 2. In this utility model, through the coordinated arrangement of a series of structures such as the mold positioning and fixing mechanism, when the worker performs automatic center positioning of the hardware mold, the worker hoists the hardware mold to the relatively central position on the upper surface of the top plate, and after the bottom of the hardware mold contacts the top of the bullseye caster, the worker activates the second hydraulic telescopic rod and puts the second hydraulic telescopic rod into a retracted working state. When the second hydraulic telescopic rod retracts, it will drive two moving plates to move simultaneously along the central area of ​​the guide rod. When the two moving plates move, they will drive four L-shaped positioning clamps to move. During the movement of the L-shaped positioning clamps, when the inner side wall of one or more L-shaped positioning clamps contacts the outer wall of the hardware mold, it will drive the hardware mold to perform automatic center positioning. When the inner sides of the four L-shaped positioning clamps are fixedly clamped at the four corners of the hardware mold, the center positioning of the hardware mold is completed. When the worker fixes and clamps the hardware mold after center positioning, the worker activates the second hydraulic telescopic rod again, so that the L-shaped positioning clamp does not exert force on the hardware mold, but the four L-shaped positioning clamps limit the four corners of the hardware mold. The worker then activates the first hydraulic telescopic rod, so that the first hydraulic telescopic rod drives the lifting plate to move downward. After the worker moves the bullseye caster to below the top plate, the hardware mold is now on the surface of the top plate. When the worker activates the second hydraulic telescopic rod again, so that the second hydraulic telescopic rod is in the retracted working state, the four L-shaped positioning clamps can fix and clamp the hardware mold. Thus, this utility model can automatically center and fix the hardware mold without the need for manual center positioning, further improving the efficiency of automatic center positioning and fixing of the hardware mold.

[0037] like Figure 1-9 As shown, a fixed auxiliary bracket for hardware molds includes a mounting component 100, on which a mold moving mechanism 200 and a mold positioning and fixing mechanism 300 are provided;

[0038] The mold moving mechanism 200 is composed of a first hydraulic telescopic rod 210, a lifting plate 220, a bullseye caster 230, and a guide assembly 240. The first hydraulic telescopic rod 210 is installed at the center of the lower surface of the lifting plate 220. When the first hydraulic telescopic rod 210 is activated, it can drive the lifting plate 220 and the bullseye caster 230 to move in the Y-axis direction. The bullseye caster 230 is installed on the upper surface of the lifting plate 220 and is arranged in a rectangular array. When the top of the bullseye caster 230 contacts the bottom of the metal mold, the metal mold is in a state that is easy to move.

[0039] The mold positioning and fixing mechanism 300 is provided with two movable plates 340. A second hydraulic telescopic rod 310 is installed on the outer wall of the movable plate 340 on one side. A connecting rod 330 is installed on the lower surface of both movable plates 340. The connecting rod 330 is movably connected to the movable plate 340 through a movable pin. The other ends of the two connecting rods 330 are respectively installed at both ends of the rotating plate 320, and the connecting rod 330 is movably connected to the rotating plate 320 through a movable pin. When the second hydraulic telescopic rod 310 is activated to extend or retract, it will drive one movable plate 340 to move. When one movable plate 340 moves, it will drive the other movable plate 340 to move through the connecting rod 330, the rotating plate 320 and other structures.

[0040] A second rotating shaft 360 is installed in the bearings at both the front and rear ends of the surface of the movable plate 340. An L-shaped positioning clamp 361 is installed at the top of the second rotating shaft 360, and an L-shaped spring plate 362 is installed at the bottom of the second rotating shaft 360. A second connecting post 363 is provided at the bottom of the L-shaped spring plate 362. The second connecting post 363 is connected to the first connecting post 343 through a tension spring 370. The first connecting post 343 is located at both the front and rear ends of the lower surface of the movable plate 340. Limiting rods 342 are installed at both the front and rear ends of the lower surface of the movable plate 340. With the coordinated arrangement of the L-shaped spring plate 362, tension spring 370, limiting rods 342, and second rotating shaft 360, when the L-shaped positioning clamp 361 no longer fixes and clamps the metal mold and no longer contacts the metal mold, the L-shaped spring plate 362 moves to its initial position under the action of the tension spring 370.

[0041] The mounting assembly 100 is provided with a support plate 130. Both sides of the upper surface of the support plate 130 are connected to the top plate 110 through connecting plates 120. The top plate 110 has a first through hole 111 in the central area of ​​its surface. The first through holes 111 are distributed in a rectangular array. Both sides of the surface of the support plate 130 have strip-shaped slot holes 112. Both sides of the lower surface of the support plate 130 are equipped with support frames 140.

[0042] Guide components 240 are installed on both sides and the front and rear ends of the lower surface of the lifting plate 220. The bottom ends of the four guide components 240 are respectively installed on both sides and the front and rear ends of the upper surface of the support plate 130. The moving plate 340 is located between the top plate 110 and the support plate 130. The setting of the guide components 240 plays a role in limiting and guiding the movement of the lifting plate 220, thereby enhancing the stability of the lifting plate 220 during movement. The first hydraulic telescopic rod 210 is installed at the center of the upper surface of the support plate 130.

[0043] The outer wall of the movable plate 340 has a second through hole 341 at both the front and rear ends. A guide rod 350 is installed in the second through hole 341. The outer wall of the guide rod 350 and the hole wall of the second through hole 341 are in clearance fit. Both ends of the guide rod 350 pass through the second through hole 341 on the two movable plates 340 and are respectively installed on the outer wall of the two support frames 140. Because the outer wall of the guide rod 350 and the hole wall of the second through hole 341 are in clearance fit, the movement of the movable plate 340 can be limited and guided.

[0044] Both the rotating plate 320 and the movable plate 340 are located below the support plate 130. The first rotating shaft 321 is installed at the center of the upper surface of the rotating plate 320, and the other end of the first rotating shaft 321 is installed in the bearing at the center of the lower surface of the support plate 130.

[0045] The top end of the second rotating shaft 360 passes through the strip-shaped slot 112, the L-shaped positioning clamp 361 is located above the top plate 110, and the outer wall of the second rotating shaft 360 and the hole wall of the strip-shaped slot 112 are in clearance fit.

[0046] The second hydraulic telescopic rod 310 is installed at the rear end of the lower surface of the support plate 130.

[0047] Working Principle: When in use, an external power supply is connected. When the worker installs and fixes the hardware mold, after hoisting the mold to the relatively central position on the upper surface of the top plate 110, the worker activates the first hydraulic telescopic rod 210, causing it to move the lifting plate 220 upwards. After the lifting plate 220 moves to a certain position, the top of the bullseye caster 230, penetrating the first through hole 111 on the surface of the top plate 110, lifts the hardware mold on the top plate 110 to a certain height. Then, the bottom of the hardware mold contacts the top of the bullseye caster 230, placing the hardware mold in a easily movable state, thus preventing the hardware mold from colliding with the installation platform. Excessive friction between the components 100 can cause difficulties in moving the hardware mold during automatic center positioning. To improve the efficiency of automatic center positioning and clamping of the hardware mold, when the operator performs automatic center positioning, the hardware mold is hoisted to the relatively central position on the upper surface of the top plate 110, and after the bottom of the hardware mold contacts the top of the bullseye caster 230, the operator activates the second hydraulic telescopic rod 310, causing it to retract. When the second hydraulic telescopic rod 310 retracts, it drives two moving plates 340 to move simultaneously along the central area of ​​the guide rod 350. During movement, the four L-shaped positioning clamps 361 will move. As the L-shaped positioning clamps 361 move, when the inner wall of one or more L-shaped positioning clamps 361 contacts the outer wall of the hardware mold, the hardware mold will automatically center-position. When the inner sides of all four L-shaped positioning clamps 361 are fixedly clamped at the four corners of the hardware mold, the center positioning of the hardware mold is complete. When the operator fixes the hardware mold after center positioning, the operator will activate the second hydraulic telescopic rod 310 again, so that the L-shaped positioning clamps 361 do not exert force on the hardware mold, but the four L-shaped positioning clamps 361 limit the movement of the four corners of the hardware mold. When in use, the operator activates the first hydraulic telescopic rod 210, causing it to move the lifting plate 220 downwards. After the operator moves the bullseye caster 230 below the top plate 110, the hardware mold is positioned on the surface of the top plate 110. When the operator activates the second hydraulic telescopic rod 310 again, causing it to retract, the four L-shaped positioning clamps 361 can fix and hold the hardware mold. Thus, this utility model can automatically center and fix the hardware mold, eliminating the need for manual center positioning and further improving the efficiency of automatic center positioning and fixing of the hardware mold.

[0048] The above description is merely a preferred embodiment of this utility model and is not intended to limit the invention. For those skilled in the art, various modifications and variations can be made to this invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this invention should be included within the protection scope of this invention.
