Description

Technical Field

[0001] This utility model belongs to the field of stamping die technology, specifically a die structure for rapid demolding. Background Technology

[0002] Stamping dies are special process equipment used in cold stamping to process materials (metal or non-metal) into parts (or semi-finished products). They are called cold stamping dies (commonly known as cold stamping dies). At room temperature, pressure is applied to the material using a die mounted on a press, causing it to separate or plastically deform, thereby obtaining the desired part.

[0003] A mold capable of rapid demolding, with publication number CN 210208318 U, includes a base plate and a worktable. The bottom of the worktable is fixedly connected to the top of the base plate. A fixing groove is provided in the middle of the top of the worktable, and a buffer plate is movably connected inside the fixing groove. Elastic plates are fixedly connected to both sides of the bottom of the buffer plate. A fixing post is fixedly connected to the bottom of the inner wall of the fixing groove and between the two opposite sides of the elastic plates. A sliding block is slidably connected to the surface of the fixing post. Buffer springs are fixedly connected to both sides of the bottom of the sliding block, and the bottom end of the buffer spring is fixedly connected to the bottom of the inner wall of the fixing post.

[0004] In the process of using the aforementioned mold that enables rapid demolding, the rapid demolding mechanism mainly relies on springs. After long-term use, the elastic modulus of the springs will change, and the compression and elongation of the springs cannot be precisely controlled. There is even a risk that the processed parts cannot be ejected normally, resulting in the inability to achieve rapid demolding.

[0005] Therefore, a mold structure for rapid demolding is proposed to address the above problems. Utility Model Content

[0006] To address the problems mentioned in the background section, this invention provides a mold structure for rapid demolding, which has the advantage of maintaining good demolding function after long-term use.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a mold structure for rapid demolding, including a punch, a die at the bottom of the punch, a base fixedly connected to the bottom of the die, a worm gear inside the base, a drive shaft passing through the worm gear, gears at both ends of the drive shaft, and the gears, drive shaft, and worm gear arranged coaxially, a rack meshing with the outer side of the gears, and a push plate fixedly connected to the top of the rack.

[0008] Preferably, the bottom of the die has a square hole, and a release module is slidably disposed inside the square hole, and the square hole and the release module have the same size.

[0009] By adopting the above technical solution, during the stamping process, the bottom of the ejector module is squeezed against the square hole, and the top of the ejector module is squeezed against the product, which prevents the product from deforming during the stamping process. After the product is stamped, the product is ejected by the upward movement of the ejector module.

[0010] Preferably, a second square hole is formed at the bottom center of the first square hole, and a push plate is slidably provided inside the second square hole.

[0011] By adopting the above technical solution, the push plate can move vertically without tilting due to the constraint of the second square hole.

[0012] Preferably, the base has an installation compartment inside, the bottom of the installation compartment is fixedly provided with a track, and a rack is slidably provided on the outer side of the track.

[0013] By adopting the above technical solution, the horizontal deviation when the rack moves up and down is reduced, and the friction between the rack and square hole three, and between the push plate and square hole two is reduced.

[0014] Preferably, the top of the base has a square hole three, and a rack is slidably disposed inside the square hole three.

[0015] By adopting the above technical solution, the rack can move up and down inside the square hole three.

[0016] Preferably, an adjustment handle is provided on one side of the base, and a worm gear is fixedly connected to the output end of the adjustment handle, with a worm wheel meshing in the middle of the worm gear.

[0017] By adopting the above technical solution, it is convenient to rotate the worm after stamping, thereby causing the worm to drive the worm wheel to rotate.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] 1. This utility model drives the worm gear to rotate by adjusting the handle. The motion is transmitted in sequence through the worm wheel, transmission shaft, gear, and rack, so that the push plate drives the demolding module to move in the vertical direction. The upward movement of the demolding module pushes the workpiece out of the cavity mold, realizing rapid demolding. Since no spring or similar elastic parts are used, the demolding effect of this rapid demolding component will not change after long-term use.

[0020] 2. By setting the square hole and the ejector module to be the same size, the ejector module can act as part of the die when rapid demolding is not required, so that there are no obvious holes at the bottom of the die. When the product is being stamped, the possibility of stamping problems caused by holes on the bottom surface is reduced, and the stamping success rate of this mold structure is improved.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] The following describes an embodiment of this utility model based on its overall structure.

[0030] like Figures 1 to 6 As shown, this utility model provides a mold structure for rapid demolding, including a punch 1, a die 2 at the bottom of the punch 1, a base 7 fixedly connected to the bottom of the die 2, a worm gear 13 inside the base 7, a drive shaft 12 passing through the inside of the worm gear 13, gears 11 at both ends of the drive shaft 12, and the gears 11, drive shaft 12, and worm gear 13 are arranged coaxially, a rack 10 meshing with the outer side of the gears 11, and a push plate 6 fixedly connected to the top of the rack 10.

[0031] The bottom of the die 2 has a square hole 3, and a stripping module 4 is slidably disposed inside the square hole 3. The square hole 3 and the stripping module 4 have the same size. During the stamping process, the bottom of the stripping module 4 is squeezed against the square hole 3, and the top of the stripping module 4 is squeezed against the product to prevent the product from deforming during the stamping process. After the product is stamped, the product is ejected by the upward movement of the stripping module 4.

[0032] A square hole 5 is provided at the bottom center of square hole 3. A push plate 6 is slidably provided inside square hole 3. Due to the constraint of square hole 3, push plate 6 can move in the vertical direction without tilting.

[0033] The base 7 has an installation chamber 8 inside, and a track 15 is fixedly installed at the bottom of the installation chamber 8. A rack 10 is slidably installed on the outside of the track 15 to reduce the horizontal deviation when the rack 10 moves up and down, and to reduce the friction between the rack 10 and the square hole 9, and between the push plate 6 and the square hole 5.

[0034] The top of the base 7 has a square hole 3 9, and a rack 10 is slidably installed inside the square hole 3 9. The rack 10 can move up and down inside the square hole 3 9.

[0035] An adjustment handle 16 is provided on one side of the base 7. A worm gear 14 is fixedly connected to the output end of the adjustment handle 16. A worm wheel 13 is engaged in the middle of the worm gear 14, which facilitates the rotation of the worm gear 14 after the stamping is completed, thereby causing the worm gear 14 to drive the worm wheel 13 to rotate.

[0036] The structural design of the mold is existing technology and will not be described in detail here. In addition, this utility model also includes a power supply, a controller and a switch, which are not the main technical points of this patent and will not be described in detail here.

[0037] The working principle and process of a mold structure for rapid demolding:

[0038] During the stamping process, the ejector module 4 is located at the bottom of the square hole 3, and the top of the ejector module 4 is flush with the bottom of the die 2. When the product is pressed into the die 2, the ejector module 4 and the die 2 together extrude pressure on the product, completing the stamping process. After stamping, when rapid demolding is performed, the adjusting handle 16 starts to rotate. The adjusting handle 16 drives the worm gear 14 to rotate, which in turn drives the worm wheel 13 to rotate. The worm wheel 13 then drives the transmission shaft 12 to rotate. The worm wheel 13 is connected to the gear 11 through the transmission shaft 12. The rotation of the transmission shaft 12 drives the gear 11 to rotate, which in turn drives the rack 10 to move upward. Because the rack 10 is constrained by the track 15, the rack 10 can only move upward along the track 15. The top of the rack 10 is fixedly connected to the push plate 6, which pushes the ejector module 4 to slide upward. Because the push plate 6 is constrained by the square hole 2 5, the push plate 6 slides upward along the square hole 2 5. Because the ejector module 4 is constrained by the square hole 3, the ejector module 4 slides upward along the square hole 3. The ejector module 4 pushes the product out from the bottom of the die 2 by sliding upward, thus completing the rapid demolding. By reversing the adjustment handle 16, the ejector module 4 can be moved downward into the interior of the square hole 3. After the bottom of the ejector module 4 contacts the bottom of the square hole 3, the subsequent parts can be stamped.
