Detailed Implementation

[0046] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] Example 1

[0048] like Figures 1 to 5 As shown, a forming mold frame with an automatic demolding mechanism includes a base 100, an upper plate 101, a lower plate 102, a female mold mounting plate 103, and a demolding rod 104. The upper plate 101 and the lower plate 102 are both slidably connected to the base 100, with the upper plate 101 located above the lower plate 102. The female mold mounting plate 103 is located between the upper plate 101 and the lower plate 102 and is fixedly connected to the base 100. A female mold 107 is fixedly mounted on the female mold mounting plate 103. An upper punch 108 is fixedly mounted on the upper plate 101, and a lower punch 109 is fixedly mounted on the lower plate 102. The upper punch 108 and the lower punch 109 are arranged opposite to each other, and both the upper punch 108 and the lower punch 109 can extend into the female mold 107.

[0049] The demolding rod 104 is in sliding connection with the upper plate 101 and the lower plate 102, the spring 105 is sleeved on the demolding rod 104, the two ends of the spring 105 are respectively in abutment with the upper plate 101 and the lower plate 102, the two ends of the demolding rod 104 are fixed with the limiting piece 106, the movement of the upper plate 101 and the lower plate 102 is limited by the limiting piece 106 to prevent the demolding rod 104 from being separated from the demolding rod 104; through the structure of the demolding rod 104 and the spring 105, the lower plate 102 and the lower punch 109 on the lower plate 102 can be driven to move upward to eject the workpiece while the movement of the upper plate 101 is not affected.

[0050] The number of the demolding rod 104 is set according to actual conditions, and one or more demolding rods 104 can be arranged, and preferably two demolding rods 104 are arranged.

[0051] In use, the shaping mold base is placed at the hydraulic machine 200, the workpiece to be shaped is placed in the cavity 107, and the four-column hydraulic machine 200 is pressed downward, the upper punch 108 drives the product to enter the cavity 107, the product abuts against the lower punch 109, the lower punch 109 drives the lower plate 102 of the shaping mold base to descend, and the lower plate 102 stops descending after contacting the base 100, at this time, the upper plate 101 continues to move downward and compresses the spring 105, so that the upper punch 108 and the lower punch 109 fully extrude the workpiece to be shaped, and the shaping process ends after pressure delay.

[0052] The spring 105 has two functions: one is to reduce the impact vibration of the lower punch assembly when the upper plate 101 of the mold base moves upward quickly; and the other is that when the lower plate 102 moves downward to the position, the lower punch 109 is in place in advance through the spring force, so as to reduce the risk of position deviation of the product entering the cavity.

[0053] After the shaping is completed, the oil cylinder of the hydraulic machine 200 moves upward, the upper plate 101 also moves upward, and the lower plate 102 is driven to move upward by the limiting piece 106 at the lower end of the demolding rod 104, so that the lower punch 109 on the lower plate 102 takes out the shaped workpiece; after the shaped workpiece is taken out, a new workpiece is placed to continue the shaping.

[0054] Further, the upper plate 101 can be directly connected with the hydraulic machine 200, but when the positioning sensor of the hydraulic machine 200 fails, the upper plate 101 will continue to move upward, and the mold base will be damaged as a whole.

[0056] In use, the pressing block flange 111 is connected with the hydraulic machine 200, so that when the conventional hydraulic machine 200 is not accurately positioned, the upper plate 101 will be pulled to break the pull pin 112 in the process, thereby ensuring that the shaping mold frame will not be damaged.

[0057] Further, the sliding connection between the upper plate 101, the lower plate 102 and the base 100 can be achieved in various structures, such as arranging sliding rails and the like; preferably, the following structure is arranged:

[0063] Further, the upper punch 108, the lower punch 109 and the female die 107 can be fixedly connected with the upper plate 101, the lower plate 102 and the female die mounting plate 103; but in order to facilitate installation and replacement, the corresponding upper punch block 119 and the lower punch block 120 can be arranged; the upper punch 108 is fixedly connected with the upper plate 101 through the upper punch block 119, and the lower punch 109 is fixedly connected with the lower plate 102 through the lower punch block 120; similarly, the female die 107 can be fixedly connected with the female die mounting plate 103 through the female die pressing plate 121.

[0076] In the shaping process, whether one of the material pickup gripper 202 is always on the cavity 107, so as to save the time of gripper clamping and loosening.

[0077] Specifically: the cylinder body of the first telescopic cylinder 204 is fixedly connected with the support frame 203, and the telescopic rod thereof can extend into the feeding groove 206, thereby pushing the workpiece in the feeding groove 206 to move.
