Abstract
Description
Technical Field
[0001] This utility model relates to the field of demolding and material handling technology for parts, specifically to an automatic demolding and material handling device for demolding parts from bottom to top. Background Technology
[0002] In the vulcanization production of sealing components, the simplest and most conventional demolding method is top-down demolding, with the removed parts falling directly onto a conveyor belt and being transported away to the next cycle of the equipment. However, due to factors such as part structure and production process, many parts are in the opposite direction, and demolding can only be done from bottom to top. While existing bottom-up demolding methods separate parts from the mold core, gravity causes them to fall back onto the core, requiring manual removal before they can enter the next cycle, resulting in low efficiency. Furthermore, during demolding, due to the tight fit between the part and the mold core, the part may even fly out of the mold upon release, causing it to fall to the ground and become unusable, or even posing a safety hazard.
[0003] Therefore, there is an urgent need to design a safe, efficient, and rhythmically stable automatic demolding and material handling device suitable for demolding parts from bottom to top. Summary of the Invention
[0004] To address the problems of manual material handling and parts flying off during demolding in existing technologies, this invention provides an automatic demolding and material handling device for demolding parts from bottom to top, eliminating the need for manual material handling and preventing parts from flying off during demolding.
[0005] The technical solution of this utility model is as follows:
[0006] An automatic demolding and material handling device for bottom-to-top demolding parts includes a reverse demolding ejection mechanism, an upper clamping mechanism, and a material handling mechanism. The material handling mechanism is fixedly connected to the upper clamping mechanism and is located above the reverse demolding ejection mechanism. The upper clamping mechanism moves up and down, driving the material handling mechanism to move closer to or away from the reverse demolding ejection mechanism. The material handling mechanism includes grippers, a three-jaw cylinder, a pressure block, a height-equalizing bolt, and an anti-breakage / flying pressure ring. The grippers are connected to the three-jaw cylinder, and the pressure block is positioned between two adjacent grippers and matches the position of the mold core. A connecting hole is provided through the pressure block, and the height-equalizing bolt passes through the connecting hole and is fixedly connected to the anti-breakage / flying pressure ring, which matches the demolded part. A wear-resistant sleeve is provided between the height-equalizing bolt and the connecting hole, and a spring is fitted onto the portion of the height-equalizing bolt located between the pressure block and the anti-breakage / flying pressure ring.
[0007] Furthermore, the reverse demolding ejection mechanism includes a demolding cylinder, a mold core carrier, and a demolding plate. The demolding plate is arranged circumferentially on the mold core carrier and protrudes horizontally from the mold core carrier. A mold core is provided on the mold core carrier, and the part for demolding is nested on the mold core. The demolding cylinder is connected to the demolding plate, and the demolding cylinder drives the demolding plate to move upward to eject the part from the mold core.
[0008] Furthermore, the upper pressing mechanism includes an upper pressing cylinder and an upper lifting plate. The upper lifting plate is connected to the output end of the upper pressing cylinder, and the upper lifting plate is fixedly connected to the pressing block through a connecting rod two perpendicular to the upper lifting plate.
[0009] Furthermore, during the pressing process of the upper pressing mechanism, the pressing block contacts the mold core, and the anti-collision and flying pressure ring contacts the part to be demolded.
[0010] Furthermore, the bolt head of the equal-height bolt is positioned above the pressure block.
[0011] Furthermore, the wear-resistant sleeve allows the equal-height bolts to move up and down on the connection hole, forming an elastic floating connection structure.
[0012] The beneficial effects achieved by this utility model are as follows:
[0013] In the process of demolding parts from bottom to top, this utility model uses an upper clamping mechanism and a material picking mechanism set at the same station to prevent parts from flying off during the picking process and to promptly pick up the demolded parts after demolding by the material picking mechanism, thus eliminating safety hazards and improving work efficiency.

[0030] like Figures 1-8 As shown, the automatic demolding and material handling device for demolding parts from bottom to top is used in production lines where parts need to be automatically removed from the demolding process from bottom to top. Its advantages are safety, high efficiency, stable cycle time, and labor saving.
[0031] like Figure 8 This is a schematic diagram of part 4, which needs to be demolded from bottom to top, as shown below. Figure 5 As shown, the part to be demolded 4 is nested on the mold core 108, and the part to be demolded 4 includes, but is not limited to, plastic parts and rubber parts. The demolding of this part is from bottom to top.
[0032] A schematic diagram of the automatic part-removing device for demolding from bottom to top is shown below. Figures 1-4 As shown, it is divided into three main parts: reverse demolding ejection mechanism 1, upper clamping mechanism 2, and material handling mechanism 3. The purpose of this device is to remove the part 4 to be demolded without risk and to automatically handle the material.
[0033] In this embodiment, the reverse demolding ejection mechanism 1 in the automatic material handling device for demolding parts from bottom to top has the following structure: Figure 5As shown, it includes a demolding cylinder 101, a lower support plate 102, a support block 103, a lower lifting plate 104, a connecting rod 105, a demolding template 106, a mold core carrier 107, and a mold core 108.
[0034] The assembly relationship is as follows: the demolding cylinder 101 is installed on the lower part of the lower support plate 102, the support block 103 is installed on the upper part of the lower support plate 102, the lower lifting plate 104 is connected to the piston rod of the demolding cylinder 101, the connecting rod 105 is connected to the lower lifting plate 104, the support block 103 is provided with a hole, the connecting rod 105 passes through the hole on the support block 103 and is connected to the demolding template 106, the connecting rod 105 can slide up and down along the hole on the support block 103, the lower lifting plate 104, the connecting rod 105, and the demolding template 106 are driven up and down by the demolding cylinder 101, the mold core carrier 107 is installed on the support block 103, the mold core 108 is placed on the mold core carrier 107, and the demolding part 4 that needs to be demolded in reverse is nested on the mold core 108.
[0035] The basic motion relationship is as follows: the piston rod of the demolding cylinder 101 pushes out, driving the lower lifting plate 104, connecting rod 105, and demolding plate 106 to push out. The demolding plate 106, together with the upper clamping mechanism 2 and the material picking mechanism 3, pushes the part 4 to be demolded out of the mold core 108 and automatically picks it up.
[0036] Specifically, the structure of the upper clamping mechanism 2 in the automatic material handling device for demolding parts from bottom to top is as follows: Figure 6 As shown, it includes a support member 201, an upper support plate 202, an upper pressure cylinder 203, and an upper lifting plate 204.
[0037] The assembly relationship is as follows: the support member 201 is installed on the lower support plate 102 in the reverse demolding ejection mechanism 1, the upper support plate 202 is installed on the support member 201, the upper pressure cylinder 203 is installed on the upper support plate 202, and the upper lifting plate 204 is connected to the piston end of the upper pressure cylinder 203.
[0038] The basic motion relationship is as follows: the piston rod of the upper pressure cylinder 203 pushes out, driving the upper lifting plate 204 to move downward.
[0039] The material handling mechanism 3 is structured as shown in Figure 7. It includes a connecting rod 301, a pressure block 302, a three-jaw cylinder 303, a gripper 304, a wear-resistant sleeve 305, a spring 306, an equal-height bolt 307, and an anti-collision pressure ring 308.
[0040] The assembly relationship is as follows: the upper end of connecting rod 301 is connected to the upper lifting plate 204 in the upper clamping mechanism 2; the pressure block 302 is connected to the lower end of connecting rod 301; the three-jaw cylinder 303 is installed on the pressure block 302; the gripper 304 is installed on the three-jaw cylinder 303, and the opening and closing of the gripper 304 is controlled by the three-jaw cylinder 303; the wear-resistant sleeve 305 is installed on the pressure block 302; the equalizing bolt 307 passes through the wear-resistant sleeve 305 and the spring 306 and is connected to the anti-collision pressure ring 308. Figure 7 As shown, the large end of the equal-height bolt 307 is on top, and the threaded part is connected to the anti-breakage and flyback pressure ring 308. In this structure, the equal-height bolt 307 slides through the wear-resistant sleeve 305 without completely disengaging. When the anti-breakage and flyback pressure ring 308 is subjected to an upward force, the spring 306 is compressed; when the anti-breakage and flyback pressure ring 308 is not subjected to an upward force, the spring 306 is not compressed.
[0041] The automatic material handling device for demolding parts of this utility model, which achieves demolding and automatic material handling of the part 4 to be demolded from bottom to top, works as follows: The piston rod of the upper pressure cylinder 203 pushes out, driving the upper lifting plate 204 to move downward. The upper lifting plate 204 drives the entire material handling mechanism 3 to move downward until the pressure block 302 of the material handling mechanism 3 presses down on the upper part of the mold core 108. At this time, the anti-collision pressure ring 308 presses on the undemolded part 4 to be demolded, and the equalizing bolt 307 slides upward about 5mm along the wear-resistant sleeve 305, and the spring 306 is compressed about 5mm. This step is used to fix the mold core 108 to prevent displacement or other malfunctions during demolding. Subsequently, the piston rod of the demolding cylinder 101 pushes out, driving the lower lifting plate 104, connecting rod 105, and demolding plate 106 to move upward. The demolding plate 106 rises to press against the part to be demolded 4 and continues to rise until the part to be demolded 4 is completely separated from the mold core 108 and successfully demolded. During this process, the anti-collision pressure ring 308 always presses on the upper part of the part to be demolded 4. The equal height bolt 307 slides upward along the wear-resistant sleeve 305 for about 10mm, and the spring 306 is further compressed. This time, the compression is about 10mm. The impact accumulated when the part to be demolded 4 is demolded is absorbed by the spring 306, preventing the part to be demolded 4 from collapsing. After the demolded part 4 is completely detached from the mold core 108 and successfully demolded, the piston rod of the demolding cylinder 101 stops pushing out. The three-jaw cylinder 303 drives the gripper 304 to close and grasp the demolded part 4. The piston rod of the demolding cylinder 101 retracts, causing the demolding plate 106 to return to its original position. The piston rod of the upper pressure cylinder 203 retracts, causing the upper lifting plate 204 to move upward. The upper lifting plate 204 drives the entire material handling mechanism 3 and the demolded part 4 to move upward, completing the grasping action. At this point, the reverse demolding automatic material handling action of the demolded part 4 is completed, and the equipment can now realize the automatic material handling of reverse demolded parts. The grasped demolded part 4 will be placed in the next station to allow the equipment to enter a cycle. Its structure is irrelevant to this application and will not be described.
[0042] The embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the scope of protection of the claims of this utility model.
