Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a mold reflux lifting module. Background Technology

[0002] In modern industrial production, molds, as key forming tools, are widely used in the manufacturing process of various products. Especially on automated production lines that require batch and high-efficiency production and involve the movement of molds between different workstations, the return and lifting operations of molds are important links to ensure smooth production processes and improve production efficiency.

[0003] Currently, pneumatic thrust is the primary power source for moving molds, but its magnitude is difficult to control precisely. When the pneumatic thrust is too small, it cannot overcome the friction between the mold and the slide, as well as other possible resistance forces, causing the mold to be unable to move to the position required for the next process.

[0004] Furthermore, the mold and the slide table are often tilted or misaligned, and not parallel to each other. This positioning deviation causes uneven force distribution between the mold and the slide table when the cylinder pushes the mold. When the cylinder applies thrust, because the mold and the slide table are not parallel, some areas experience excessive force while others experience insufficient force, making the mold more prone to jamming during movement. Simultaneously, this uneven force makes manual operation extremely difficult, requiring operators to expend considerable physical strength and energy to adjust the mold's position, and even then, accurate positioning is difficult to guarantee. More seriously, manual operation requires applying significant force to overcome the jamming between the mold and the slide table, posing a safety risk that could result in operator injury and damage to the mold and slide table, increasing production costs.

[0005] Therefore, this application develops a mold recirculation lifting module to solve the problems existing in the prior art. Utility Model Content

[0006] The purpose of this utility model is to provide a mold recirculation lifting module to solve the problem of mold jamming caused by uneven force during mold recirculation in the prior art.

[0007] The technical solution of this utility model is: a mold recirculation lifting module, comprising:

[0008] A partition plate, wherein the partition plate is provided with partition holes to provide movement space;

[0009] A lifting mechanism, wherein the lifting mechanism passes through the partition plate and its main body is located at the center of the partition hole;

[0010] A tilting device is installed on top of the lifting mechanism and moves synchronously with the lifting mechanism. During the lifting process, the angle of the tilting device relative to the horizontal plane changes. When the mold is placed on the tilting device, the two sides of the mold remain parallel to the two sides of the tilting device. By changing the angle of the tilting device, the mold can slide along the tilting surface of the tilting device.

[0011] A baffle is positioned in front of the mold in the sliding direction and installed on the partition plate to prevent the mold from disengaging from the tilting device.

[0012] Preferably, the tilting device includes a support part and a moving part. The support part is installed on the top of the lifting mechanism. The side of the moving part away from the baffle is rotatably connected to the support part, and the side of the moving part close to the baffle is elastically connected to the support part. When the side of the moving part close to the baffle moves to abut against the baffle, that side stops moving. The side of the moving part away from the baffle continues to move with the lifting mechanism, causing the moving part as a whole to tilt towards the baffle.

[0013] Preferably, a bracket and a spring are respectively provided between the support part and the moving part. The bracket is located on the side away from the baffle, and one end is fixed to the support part, while the other end is hinged to the moving part. The two ends of the spring are respectively connected to the two adjacent sides of the moving part and the support part.

[0014] Preferably, a limiting groove is formed on the side of the baffle adjacent to the partition plate, and a protrusion matching the limiting groove extends from the side of the moving part near the baffle. When the protrusion contacts the limiting groove, the moving part rotates around the contact position.

[0015] Preferably, the baffle is located at the edge of the partition hole, and the baffle is provided with a buffer plate on the side near the moving part.

[0016] Preferably, the lifting mechanism has a fixed plate at the end away from the tilting device, and multiple buffers and buffer blocks are respectively provided on the two adjacent sides of the fixed plate and the support.

[0017] Compared with the prior art, the advantages of this utility model are:

[0018] (1) The tilting device is tilted so that the mold can slide smoothly to the appropriate position. Compared with the traditional method, the cylinder movement distance is reduced, the possibility of the mold getting stuck on the tilted part is reduced, and the mold can be moved smoothly in a specific direction.

[0019] (2) A limiting groove is opened on the adjacent side of the baffle and the partition plate. The moving part extends a matching protrusion on the side close to the baffle. After the two come into contact, the moving part rotates around the contact position as the rotation center. It can change the angle according to the preset method to ensure that the moving part moves to the inclined position, so that the mold slides along the inclined surface. At the same time, it can also ensure that the inclined part and the mold are in a free state, without affecting the inclined part to return to the horizontal position and move down with the lifting mechanism.

[0026] The present invention will be further described in detail below with reference to specific embodiments:

[0027] like Figures 1-3As shown, a mold recirculation lifting module includes a partition plate 1, a lifting mechanism 2, a tilting device 3, and a baffle 4. The partition plate 1 has a partition hole 11, which provides necessary space for the movement of the lifting mechanism 2 and the tilting device 3. The lifting mechanism 2 extends through the partition plate 1 and is located at the center of the partition hole 11. The lifting mechanism 2 moves vertically, enabling the tilting device 3 to switch between horizontal and tilted positions. The tilting device 3 is installed on top of the lifting mechanism 2 and moves synchronously with it. During the lifting process, the angle of the tilting device 3 relative to the horizontal plane changes. When the mold is placed on the tilting device 3, as the angle of the tilting device 3 gradually increases, the mold can slide smoothly on the tilting surface of the tilting device 3, thus achieving movement of the mold in a specific direction. Furthermore, a baffle 4 is provided in front of the mold in the sliding direction and is fixedly installed on the partition plate 1. Its main function is to block the mold, preventing it from detaching from the tilting device 3 due to inertia or other factors during sliding, ensuring that the mold is always in the correct position, so that it can enter the next process after the lifting mechanism 2 descends.

[0028] In the traditional method, the tilting device 3 has only one horizontal position. The mold is moved onto the tilting device 3 by a cylinder. In order not to affect the next process, the mold needs to be pushed into place. Therefore, the pushing distance of the cylinder is relatively long, and it cannot be guaranteed whether the mold will tilt during the pushing process, which will cause the mold to get stuck on the tilting device 3. In this application, by setting the tilting device 3 to move from the horizontal position to the tilting position, the mold can slide smoothly to the appropriate position, while reducing the moving distance of the cylinder and reducing the possibility of the mold getting stuck.

[0029] In this embodiment, the tilting device 3 includes a support part 31 and a moving part 32. The support part 31 is installed on the top of the lifting mechanism 2 and moves up and down together with the lifting mechanism 2, providing a stable support base for the moving part 32. The side of the moving part 32 away from the baffle 4 is rotatably connected to the support part 31, so that this side of the moving part 32 can rotate freely around the connection point, thereby realizing the movement of the moving part 32 relative to the support part 31 on this side. The side of the moving part 32 near the baffle 4 is elastically connected to the support part 31, so that this side has a certain degree of elastic movement capability.

[0030] During operation, when the lifting mechanism 2 drives the tilting device 3 to move as a whole, the side of the moving part 32 closest to the baffle 4 will gradually move closer to the baffle 4. When this side moves to the point of contact with the baffle 4, the movement on this side stops due to the blocking effect of the baffle 4. At the same time, the lifting mechanism 2 continues to drive the support part 31 to move, causing the moving part 32 to rotate around the side closest to the baffle 4, thereby causing the moving part 32 to tilt towards the baffle 4 as a whole, so that the mold slides along the tilted surface.

[0031] Specifically, such as Figures 2-3 As shown, a bracket 33 and a spring 34 are provided between the support part 31 and the moving part 32. The bracket 33 is located on the side away from the baffle 4. One end is fixed to the support part 31 by welding, bolting, or other means, and the other end is connected to the moving part 32 by hinge, allowing the moving part 32 to swing at a certain angle relative to the support part 31 on this side. The two ends of the spring 34 are respectively connected to two adjacent surfaces of the moving part 32 and the support part 31. When the side of the moving part 32 close to the baffle 4 contacts the baffle 4, the spring 34 is compressed, and the movement of the moving part 32 on the side close to the baffle 4 stops. When the other side continues to move, causing the moving part 32 to tilt, the elastic force of the spring 34 will restore the moving part 32 to a horizontal position when the lifting mechanism 2 descends, thereby enabling the mold to move to the next process.

[0032] Furthermore, such as Figure 2 As shown, a limiting groove 41 is provided on the side of the baffle 4 adjacent to the partition plate 1. The moving part 32 extends a protrusion 42 that matches the limiting groove 41 on the side near the baffle 4. During the movement, as the side of the moving part 32 near the baffle 4 gradually approaches the baffle 4, the protrusion 42 on the moving part 32 will come into contact with the limiting groove 41 on the baffle 4. Once the protrusion 42 comes into contact with the limiting groove 41, due to the constraint of the limiting groove 41 on the protrusion 42, the moving part 32 will start to rotate around the contact position between the protrusion 42 and the limiting groove 41 as the rotation center, so that the moving part 32 can change the angle in a preset manner, thereby meeting the movement requirements of the mold and ensuring the stability and accuracy of the mold during the reflow lifting process.

[0033] To reduce the impact wear of the mold, the baffle 4 is set at the edge of the partition hole 11, and a buffer plate 43 is installed on the side of the baffle 4 near the moving part 32 of the tilting device 3. When the mold slides along the inclined surface and comes into contact with the baffle 4, the buffer plate 43 can play a buffering role, absorb and disperse part of the impact force, reduce the vibration and wear caused by the collision, extend the service life of the baffle 4, the mold and other related components, and reduce the noise during operation.

[0034] like Figure 4As shown, when moving the mold to the next process, it needs to be moved to the bottom of the partition plate 1 by the lifting mechanism 2. Therefore, a fixed plate 5 is installed at the end of the lifting mechanism 2 away from the tilting device 3. On the two adjacent sides of the fixed plate 5 and the support part 31 of the tilting device 3, multiple buffers 51 and buffer blocks 52 are respectively set, and the multiple buffers 51 and multiple buffer blocks 52 correspond one-to-one. When the lifting mechanism 2 descends to the position, the buffer 51 can absorb energy through its own elastic deformation, and the buffer block 52 plays the role of auxiliary support and further dispersing the impact force. The two work together to effectively reduce the rigid collision between the fixed plate 5 and the support part 31, and avoid the position deviation of the mold after movement due to severe vibration, thereby affecting the next process.

They should not be construed as limiting the scope of protection of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects.
