Description

Technical Field

[0001] The utility model relates to the technical field of limiting mechanisms, in particular to a mold unloading limiting mechanism. Background Art

[0002] Molds are tools used to manufacture various industrial products or parts. Through molds, raw materials can be processed into finished products of specific shapes and sizes. Molds play a very important role in the manufacturing industry and are widely used in industries such as automobile manufacturing, plastic products, and rubber products. Molds are usually composed of an upper mold and a lower mold. Products are processed by combining the upper and lower molds. However, there are still problems that need to be solved when unloading existing molds.

[0003] At present, the upper mold in the mold is usually moved by a hydraulic drive device. During the unloading process, the upper mold will rise away from the lower mold, and the staff will perform unloading operations near the lower mold. If the hydraulic drive device fails at this time, the upper mold will fall quickly and may injure the staff, causing irreparable losses. Therefore, it is necessary to design a mold unloading limit mechanism to solve the above problem. Utility Model Content

After the extrusion plate moves past the limit plate, the limit plate will extend out to block the bottom of the extrusion plate, so as to drag the extrusion plate, thereby stabilizing the fixed seat in the specified position, thereby ensuring the positioning of the upper mold. If the hydraulic drive device fails, it will not cause the upper mold to fall. At the same time, by providing the first limit rod, the stability of the upper mold during movement can also be ensured, which effectively solves the problem raised in the background technology that if the hydraulic drive device fails, the upper mold will fall quickly, which may injure the staff and cause irreparable losses, thereby achieving the technical effect of being able to effectively limit the position of the upper mold and improve the safety of unloading work.

[0024] In this embodiment, the two side panels 2 are fixedly connected with a plurality of slide grooves 11 on the side away from each other. The slide grooves 11 are connected with the mounting grooves 3. Slide blocks 12 are arranged in the slide grooves 11. The slide blocks 12 are fixedly connected with the limit plates 4. The plurality of slide blocks 12 at the same end are fixedly connected with the same connecting plate 13.

[0025] In this embodiment, the two connecting plates 13 at the same end are provided with a fixing plate 14 on the side close to each other, and the fixing plate 14 is penetrated by a limiting ring 15 and a bidirectional screw rod 16, the limiting ring 15 and the bidirectional screw rod 16 are rotatably connected to the fixing plate 14, the limiting ring 15 is rotatably connected to the bidirectional screw rod 16, and the two bidirectional screw rods 16 are both provided with a threaded sleeve 17, and the threaded sleeve 17 is threadedly connected to the bidirectional screw rod 16.

[0028] In this embodiment, a motor 21 is fixedly connected to one side of the housing 20 , and an output shaft of the motor 21 is fixedly connected to the bidirectional lead screw 16 .

[0029] In this embodiment, a circular hole 22 is formed on the mounting plate 1 .

[0030] Working principle: Fix the mounting plate 1 to the fixing frame on the top of the upper mold by bolts, place the device just above the upper mold, make the output end of the hydraulic cylinder driving the upper mold to move pass through the circular hole 22, connect the output end of the hydraulic cylinder with the connecting pin 8, fix the upper mold on the fixing seat 23, and when unloading, the upper mold needs to be raised to shrink the output end of the hydraulic cylinder, so that the connecting pin 8 can be raised, and the rising of the connecting pin 8 will drive the square plate 7 to rise, and the square plate 7 will drive the fixing seat 23 to rise, and the fixing seat 23 will be The upper mold will be driven up, and the rise of the square plate 7 will drive the collar 9 to rise. The collar 9 will move along the first limiting rod 10, and the fixed seat 23 will not deviate when moving. The upper mold will not deviate when moving. When the square plate 7 rises, it will also drive the extrusion plate 6 to move, and the extrusion plate 6 will move along the side plate 2.

When the extrusion plate 6 moves past the limiting plate 4, The spring 5 will stretch out, and the limit plate 4 will extend out to block the bottom of the extrusion plate 6. If the hydraulic system fails during the unloading work, the limit plate 4 can support the extrusion plate 6, which can ensure the stability of the upper mold and prevent it from falling quickly. When the upper mold is lowered when needed, the motor 21 is started, and the output shaft of the motor 21 will drive the bidirectional screw rod 16 to rotate, and the bidirectional screw rod 16 will drive the threaded sleeve 17 to move, and the threaded sleeve 17 will drive the sleeve plate 18 to move along the second limit rod 19, and the threaded sleeve 17 will not move when moving. When an offset occurs and the threaded sleeve 17 continues to move when it contacts the connecting plate 13, the connecting plate 13 will drive the slider 12 to move, and the slider 12 will drive the limit plate 4 to move. The limit plate 4 is no longer directly below the extrusion plate 6, so that the output end of the hydraulic cylinder can be extended to lower the upper mold. After the upper mold and the lower mold are closed, the output shaft of the motor 21 is reversed to make the two threaded sleeves 17 approach each other, and the spring 5 will stretch again to return the limit plate 4 to the initial position, and the connecting plate 13 will also return to the initial position.
