[0001] This utility model relates to the field of thermal shaping technology, and in particular to a pull-out mechanism and a thermal shaping device. Background Technology

[0002] Hot forming equipment is a commonly used piece of equipment in the manufacturing industry, mainly used for die castings. In order to solve the problems of deviation and internal stress generated during the cooling and shrinkage process of die castings, hot forming equipment is used to heat the product and apply pressure, thereby achieving the purpose of product shaping.

[0003] However, after the product has been shaped, it is usually taken directly out of the shaping mold by the worker. At this time, the product has not been completely cooled and shaped. After being freed from the mold constraint, the product size may deviate from the design tolerance due to gravity, residual stress and other factors. Furthermore, direct touch can easily cause the product to bend or dent, thereby reducing the product's precision. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a pull-out mechanism and a hot forming device, which allows workers to easily remove the entire forming mold, protecting the integrity of the product and improving product precision.

[0005] A pull-out mechanism according to a first aspect embodiment of the present invention includes: The machine is equipped with a slide rail and a pull-out table. The slide rail is parallel to the horizontal plane, and the pull-out table is equipped with a rotating seat with a rotating screw hole. The lower pressure plate is provided with a first sliding groove and a second sliding groove, and the bottom of the lower pressure plate is provided with a lower pressure plate slider, which is slidably connected to the slide rail. The lower template is located on the upper surface of the lower pressure plate; A clamping screw is threaded into a rotating screw hole, and a rotating handle is provided at one end of the clamping screw. A clamping block, one end of which is provided with a first connecting block, the first connecting block being slidably connected to a first sliding through groove, the sliding direction of the clamping block being parallel to the slide rail, and the bottom end of the first connecting block being provided with a first toothed rack; The driving block is provided with a driving groove, and the clamping screw is rotatably connected to the driving groove. One end of the driving block is provided with a second connecting block, which is slidably connected to a second sliding through groove. The sliding direction of the driving block is parallel to the slide rail, and the bottom end of the second connecting block is provided with a second rack. The gear is rotatably connected to the bottom of the lower pressure plate, and the first rack and the second rack mesh on opposite sides of the gear.

[0006] In this embodiment, a heating element is embedded in the lower pressure plate.

[0007] In this embodiment, the slide rail is provided with a limiting block, and the lower pressure plate slider is located on the side of the limiting block close to the contact block.

[0008] In this embodiment, heat-insulating handles are symmetrically arranged on the left and right sides of the lower template.

[0009] In this embodiment, the lower pressure plate is provided with a sliding groove, and the bottom of the lower template is provided with a lower template slider that matches the sliding groove.

[0010] In this embodiment, the drive groove is a T-shaped groove, and the other end of the clamping screw is provided with a frustum that mates with the drive groove.

[0011] A heat shaping device according to a second aspect of the present invention includes a pull-out mechanism according to any of the first aspects of the present invention.

[0012] In this embodiment, the system also includes a hydraulic cylinder, a frame, an upper pressure plate, an upper template, a control console, and a base arranged sequentially from top to bottom.

The base is provided with a control console, and a pull-out mechanism is provided on the base.

[0013] This utility model embodiment has at least the following beneficial effects: It is simple in overall design, easy to install and maintain. After shaping, rotating the handle drives the clamping screw, causing the drive block and the second rack to shift. Through reverse gear transmission, the first rack and the clamping block shift in the opposite direction. When the drive block shifts to one end of the second sliding groove, it pulls the lower pressure plate along the slide rail out of the shaping area. After the workpiece is placed in, reversing the handle drives the drive block and the clamping block to move towards each other to clamp the lower template. Then, the lower pressure plate is pushed into the shaping area. This not only pulls the product out of the shaping area, ensuring worker safety during operation, but also brings the workpiece closer to the worker, providing ample operating space for easy removal and placement of the lower template. This allows the product to cool and solidify in the mold, ensuring product integrity, preventing direct contact with the product from causing shape defects, improving product precision, and reducing economic losses.

[0021] The following is for reference only. Figure 1 To be continued Figure 6 This describes the pull-out mechanism and heat-forming device of embodiments of the present utility model.

[0022] Reference Figures 1 to 5 The first aspect of this utility model provides a pull-out mechanism, including a machine base 1, a lower pressure plate 2, a lower template 3, a clamping screw 4, a clamping block 5, a drive block 6, and a gear 7. The machine base 1 is provided with a slide rail 11 and a pull-out table 12. The slide rail 11 is parallel to the horizontal plane. The pull-out table 12 is provided with a rotating seat 121, which has a rotating screw hole 122. The lower pressure plate 2 is provided with a first sliding groove 21 and a second sliding groove 22, and a lower pressure plate slider 24 is provided at the bottom of the lower pressure plate 2. The lower pressure plate 2 is slidably connected to the slide rail 11 via the lower pressure plate slider 24. The lower template 3 is provided on the upper surface of the lower pressure plate 2. One end of the clamping screw 4 is provided with a rotating handle 41, which is threadedly connected to the rotating screw hole 122. One end of the clamping block 5 is... The first connecting block 51 is provided at one end, and the bottom end of the first connecting block 51 is provided with a first rack 52. The first connecting block 51 is slidably connected to the first sliding through groove 21. The first rack 52 is located at the bottom of the lower pressure plate 2. The sliding direction of the clamping block 5 is parallel to the horizontal plane. The driving block 6 is provided with a driving groove 61 and a second connecting block 62. The bottom end of the second connecting block 62 is provided with a second rack 63. The other end of the clamping screw 4 is rotatably connected to the driving groove 61. The sliding direction of the driving block 6 is parallel to the horizontal plane. The second rack 63 is located at the bottom of the lower pressure plate 2. The gear 7 is rotatably connected to the bottom of the lower pressure plate 2. The first rack 52 and the second rack 63 are respectively meshed on opposite sides of the gear 7. This pull-out mechanism has a simple overall structure and is easy to install and maintain.

[0023] It is understandable that multiple sets of heating elements 8 are evenly distributed inside the lower pressure plate 2, and a gear shaft 25 is provided at the bottom. The gear 7 is rotatably connected to the bottom of the lower pressure plate 2 through the gear shaft 25. The heating elements 8 can be electric heating tubes used to heat the product.

[0024] It is understandable that the first connecting block 51, the second connecting block 62 and their corresponding first rack 52 and second rack 63 are all provided with corresponding threaded holes. The connection between the connecting block and the rack is a bolt-fixed connection, which facilitates the assembly, updating and maintenance of the overall mechanism.

[0025] It is understood that the drive groove 61 is a T-shaped groove, and the other end of the clamping screw 4 is provided with a frustum 42 that cooperates with the drive groove 61. The diameter of the frustum 42 is larger than the diameter of the clamping screw 4. The clamping screw 4 is movably connected to the drive groove 61 through the frustum 42, so that the clamping screw 4 can rotate in the drive groove 61 and drive the drive block 6 to reciprocate.

[0026] After the product is shaped, rotate the handle 41 clockwise. The clamping screw 4 pulls the drive block 6 to move. The second rack 63 at the bottom of the second connecting block 62 moves closer to the contact block 26. The gear 7 acts as a reaction force on the first rack 52 at the bottom of the first connecting block 51, causing the clamping block 5 to move away from the contact block 26, thus releasing the clamp on the lower template 3. When the drive block 6 moves to one end of the second sliding groove 22, continue to rotate the handle 41. The drive block 6 pulls the lower pressure plate 2 to move through the slide rail 11, pulling the lower pressure plate 2 and the lower template 3 out of the shaping area. This protects the safety of the workers' working environment and makes it easier for workers to remove the lower template 3. It also prevents the product size from deviating from the design tolerance due to gravity, residual stress, etc., after the product is freed from the mold constraint.

[0027] Similarly, the product to be shaped is placed in the lower template 3 and placed on the lower pressure plate 2. The rotating handle 41 is rotated counterclockwise, and the driving block 6 is displaced by the clamping screw 4. The second rack 63 at the bottom of the second connecting block 62 moves away from the contact block 26. The reaction force of the gear 7 on the first rack 52 at the bottom of the first connecting block 51 drives the clamping block 5 to move closer to the contact block 26. The clamping block 5 cooperates with the contact block 26 to clamp and fix the lower template 3. When the driving block 6 moves to one end of the second sliding groove 22, the rotating handle 41 is rotated again. The driving block 6 pushes the lower pressure plate 2 to move through the slide rail 11, pushing the lower pressure plate 2 and the lower template 3 into the shaping area. One action completes the pushing of the lower pressure plate 2 and the clamping of the lower template 3, increasing the worker's work efficiency.

[0028] It is understandable that the slide rail 11 is equipped with a limiting block 111, and the lower pressure plate slider 24 is located on the side of the limiting block 111 close to the contact block 26. During the process of pulling out the lower pressure plate 2, the clamping screw 4 pulls the drive block 6 to move, and the second rack 63 at the bottom of the second connecting block 62 moves to the side close to the contact block 26. The gear 7 acts as a reaction force on the first rack 52 at the bottom of the first connecting block 51, causing the clamping block 5 to move to the side away from the contact block 26, thus releasing the clamping of the lower template 3. When the drive block 6 has not moved to one end of the second sliding groove 22, the rotating handle 41 is turned, and the drive block 6 pulls the lower pressure plate 2 to move through the slide rail 11. At this time, the lower template 3 is not completely released. In the first state, after limiting the displacement of the lower pressure plate 2 on the slide rail 11 by limiting block 111, continue to rotate the rotating handle 41 to pull the drive block 6 to one end of the second sliding groove 22, so that the clamping block 5 completely releases its clamping of the lower template 3; similarly, when the drive block 6 has not moved to the other end of the second sliding groove 22, rotate the rotating handle 41, and the drive block 6 pushes the lower pressure plate 2 to generate displacement through the slide rail 11. At this time, the lower template 3 is in a state of not being fully clamped. After limiting the displacement of the lower pressure plate 2 on the slide rail 11 by limiting block 111, continue to rotate the rotating handle 41 to push the drive block 6 to the other end of the second sliding groove 22, so that the clamping block 5 completely clamps the lower template 3, thereby improving the shaping accuracy of the device.

[0029] It is understandable that heat-insulating handles 31 are symmetrically arranged on the left and right sides of the lower template 3 to facilitate the removal and removal of the lower template 3, prevent workers from being burned, and avoid product defects caused by direct contact with the product. The bottom is provided with a lower template slider 32, and the lower pressure plate 2 is provided with a sliding groove 23 corresponding to the lower template slider 32. By sliding the lower template slider 32 and the sliding groove 23, the stability of the lower template 3 on the upper surface of the lower pressure plate 2 can be increased, and the shaping accuracy of the device can be improved.

[0030] Based on the above implementation plan, see Figure 6 The second aspect of this utility model provides a heat shaping device, including the pull-out mechanism of any of the first aspects of the present invention. The heat shaping device includes a hydraulic cylinder 9, a frame 10, an upper pressure plate 13, an upper template 14, a control console 15, and a base 16 arranged sequentially from top to bottom. The output end of the hydraulic cylinder 9 extends through to the lower surface of the frame 10. The output direction of the hydraulic cylinder 9 is perpendicular to the horizontal plane. The output end of the hydraulic cylinder 9 is provided with the upper pressure plate 13. One end of the upper pressure plate 13 is provided with an upper template 14 that matches the lower template 3. The base 16 is provided with the control console 15. The control console 15 is provided with an emergency stop button 17, a heating button 18, and a start button 19 arranged sequentially from left to right. The machine base 1 is located on the base 16.

[0031] When product shaping is required, the worker places the product into the lower template 3, pushes the lower pressure plate 2 and the lower template 3 into the frame 10 by rotating the handle 41, heats the lower pressure plate 2 by pressing the heating button 18 until the product reaches the shaping temperature, presses the start button 19, and the output end of the hydraulic cylinder 9 and the upper pressure plate 13 and upper template 14 set on it press down vertically to apply pressure to the product. After the device reaches the set time, the output end of the hydraulic cylinder 9 returns to its position, and the lower pressure plate 2 is pulled out of the frame 10 by rotating the handle 41, leaving the hydraulic shaping area, ensuring that the worker can safely remove the lower template 3 together with the product and place it for cooling.

[0032] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
