Description

Technical Field

[0001] This utility model relates to an automatic stripping mold for automotive hardware stamping, belonging to the technical field of automotive hardware stamping parts. Background Technology

[0002] Automotive hardware stamping parts are metal stamping parts that make up automotive components. Among automotive hardware stamping parts, some become automotive components directly after stamping, while others need to undergo welding, machining, painting, or other processes after stamping before they can become automotive components.

[0003] Chinese Patent Publication No. CN 111036750A discloses a stamping device for automotive hardware parts, including a stamping table. Support plates are fixedly connected to both sides of the upper end of the stamping table. A top plate is fixedly connected to the upper end of the support plates. A horizontal plate is slidably connected between the opposite sidewalls of the two support plates. A stamping head is fixedly connected to the lower end of the horizontal plate. This invention, by setting up a pumping mechanism, a pushing mechanism, a first driving mechanism, a cleaning mechanism, a second driving mechanism, and a cooling mechanism, allows a reversible motor that drives the stamping head to move downwards and press, driving a sliding plug to reciprocate horizontally. This pumps coolant from the reservoir into a cooling tank, cooling the stamping head and preventing deformation due to high temperatures. Simultaneously, the heat dissipation fins cool the coolant returning to the reservoir, maintaining good cooling performance. The motor also drives a cleaning brush to reciprocate horizontally, promptly cleaning up scraps, reducing labor intensity, and avoiding hazards.

[0004] However, after the stamping of automotive parts, due to the change in shape, they are more likely to get stuck inside the mold. At this time, operators often need to spend a lot of time to manually remove the parts. This process consumes a lot of labor costs and also affects the overall efficiency of stamping automotive parts, making it inconvenient for operators to use.

[0005] To address this, an automatic stripping die for automotive hardware stamping is proposed. Utility Model Content

[0006] In view of this, the present invention provides an automatic stripping mold for automotive hardware stamping to solve or alleviate the technical problems existing in the prior art, and at least provides a beneficial option.

[0007] The technical solution of this utility model is implemented as follows:

[0008] An automatic stripping mold for automotive hardware stamping includes a worktable, a mounting frame fixedly installed on the top of the worktable, a hydraulic telescopic cylinder fixedly installed on the top of the mounting frame, a stamping device fixedly installed on the bottom of the hydraulic telescopic cylinder, a mold body placed on the top of the worktable, and insertion holes opened at the bottom of the inner cavity of the mold body.

[0009] The surface of the workbench is provided with a demolding mechanism, which includes a housing and connecting rods. The housing is fixedly installed at the bottom of the workbench. A first clamping plate is fixedly installed on the top of each of the four connecting rods. A movable rod is movably connected to the inner side of each of the four first clamping plates. A second clamping plate is movably connected to the other end of each of the four movable rods. A top plate is fixedly installed on the top of each of the four second clamping plates. A push rod is fixedly installed on the top of each top plate.

[0010] More preferably, a motor is fixedly installed at the bottom of the housing, a rotating plate is fixedly connected to the output end of the motor, connecting rods are movably connected to the front and rear sides of the top of the rotating plate, sliding blocks are movably connected to the bottom of the two connecting rods, and the four connecting rods are fixedly installed on the front and rear sides of the two sliding blocks.

[0011] More preferably, sliding grooves are provided on both the left and right sides of the bottom of the inner cavity of the box, and the bottoms of the two sliding blocks are slidably connected to the inner cavities of the two sliding grooves.

[0012] More preferably, the front and rear sides of the inner cavity of the box are provided with movable grooves, and the front and rear sides of the top plate are slidably connected to the inner cavities of the two movable grooves.

[0013] More preferably, each of the worktables has a slot on its top, and the five push rods pass through the inner cavities of the five slots and the five insertion holes and extend into the inner cavity of the mold body.

[0014] More preferably, the inner cavities of the five sockets and the inner cavities of the five slots are all in the same vertical direction, and the inner cavities of the five sockets and the five slots are all interconnected.

[0015] More preferably, electric telescopic rods are fixedly installed on both the left and right sides of the top of the workbench, and clamping plates are fixedly installed on the inner sides of the two electric telescopic rods, with the inner sides of the two clamping plates fitting against the outer side of the mold body.

[0016] More preferably, the top of the workbench is provided with movable slots on both the left and right sides, and the bottoms of the two clamping plates are slidably connected to the inner cavities of the two movable slots.

[0017] More preferably, a base plate is fixedly installed at the bottom of the workbench, and anchor bolts are threaded around the top of the base plate.

[0018] The present invention has the following advantages due to the adoption of the above technical solution:

[0019] 1. This utility model, by setting up a demolding mechanism, uses the output of a motor to rotate a rotating plate, which in turn causes the connecting rod to flip. At this time, the sliding block drives the connecting rod and the first clamping plate to move outward synchronously. Due to the movement of the first clamping plate, the movable rod flips and pushes the second clamping plate, the top plate, and the push rod upward. The push rod ejects the molded part from the inner cavity of the mold body, completing the automatic demolding process. This effectively reduces the need for operators to manually remove materials multiple times after stamping, improving the convenience and efficiency of demolding automotive parts, reducing labor costs, and making it convenient for operators to use.

[0020] 2. This utility model, by setting a sliding groove, can limit the movement of the sliding block, preventing it from shifting and affecting the demolding process. By setting a movable groove, the movement of the top plate can be limited, preventing directional deviation and ensuring proper demolding. By setting a slot, the movement of the push rod can be limited, preventing directional deviation and ensuring the part can be ejected from the mold body cavity. The slot and insertion hole, being in the same vertical direction and interconnected, facilitate the push rod's passage through both cavities. This allows for the demolding of components within the mold body's internal cavity. The electric telescopic rod and clamping plate effectively hold the mold body in place, preventing displacement of the mold body during stamping and ensuring the stamping process continues smoothly. The moving groove limits the movement of the clamping plate, preventing displacement and ensuring stability during mold clamping. Anchor bolts stabilize the entire equipment, preventing accidental tipping and ensuring the stamping of automotive parts is not affected.

[0021] The above overview is for illustrative purposes only and is not intended to be limiting in any way. In addition to the illustrative aspects, embodiments, and features described above, further aspects, embodiments, and features of the present invention will become readily apparent from the accompanying drawings and the following detailed description.

[0029] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0030] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0031] Example 1

[0032] like Figure 1-6 As shown, this utility model embodiment provides an automatic stripping mold for automotive hardware stamping, including a workbench 1, a mounting frame 3 fixedly installed on the top of the workbench 1, a hydraulic telescopic cylinder 4 fixedly installed on the top of the mounting frame 3, a stamping device 5 fixedly installed on the bottom of the hydraulic telescopic cylinder 4, a mold body 6 placed on the top of the workbench 1, and insertion holes 7 are provided at the bottom of the inner cavity of the mold body 6.

[0033] The surface of the workbench 1 is provided with a demolding mechanism 2. The demolding mechanism 2 includes a housing 201 and connecting rods 206. The housing 201 is fixedly installed at the bottom of the workbench 1. The top of each of the four connecting rods 206 is fixedly installed with a first clamping plate 207. The inner side of each of the four first clamping plates 207 is movably connected with a movable rod 208. The other end of each of the four movable rods 208 is movably connected with a second clamping plate 209. The top of each of the four second clamping plates 209 is fixedly installed with a top plate 210. The top of each top plate 210 is fixedly installed with a push rod 211. The bottom of the housing 201 is fixedly installed with a motor 202. The output end of the motor 202 is fixedly connected with a rotating plate 203. The front and rear sides of the top of the rotating plate 203 are movably connected with connecting rods 204. The bottom of each of the two connecting rods 204 is fixedly connected with a push rod 211. The device is connected by sliding blocks 205. Four connecting rods 206 are fixedly installed on the front and rear sides of two sliding blocks 205. Sliding grooves 213 are provided on the left and right sides of the bottom of the inner cavity of the box body 201. The bottom of the two sliding blocks 205 are slidably connected to the inner cavity of the two sliding grooves 213. Movable grooves 212 are provided on the front and rear sides of the inner cavity of the box body 201. The front and rear sides of the top plate 210 are slidably connected to the inner cavity of the two movable grooves 212. Slots 13 are provided on the top of the workbench 1. Five push rods 211 pass through the inner cavities of the five slots 13 and the five insertion holes 7 and extend into the inner cavity of the mold body 6. The inner cavities of the five insertion holes 7 and the inner cavities of the five slots 13 are in the same vertical direction, and the inner cavities of the five insertion holes 7 and the five slots 13 are interconnected.

[0034] By setting up a demolding mechanism 2, the rotating plate 203 rotates due to the output of the motor 202, which in turn causes the connecting rod 204 to flip. At this time, the sliding block 205 drives the connecting rod 206 and the first clamping plate 207 to move outward synchronously. Due to the movement of the moving rod 208 of the first clamping plate 207, the second clamping plate 209, the top plate 210, and the push rod 211 move upward. The push rod 211 pushes out the formed part in the inner cavity of the mold body 6, completing the automatic demolding work. This effectively reduces the need for operators to manually remove materials multiple times after stamping, improves the convenience and efficiency of demolding automotive parts, reduces labor costs, and facilitates operation. The groove 213 can limit the movement of the sliding block 205 to prevent the sliding block 205 from deviating during movement, thus affecting the demolding of the part. By setting the movable groove 212, the movement of the top plate 210 can be limited to prevent the top plate 210 from deviating in direction during movement, thus affecting the normal demolding process. By setting the slot 13, the movement of the push rod 211 can be limited to prevent the push rod 211 from deviating in direction when moving upward, thus preventing the part from being ejected from the inner cavity of the mold body 6. By setting the slot 13 and the insertion hole 7, since both are in the same vertical direction and are interconnected, the push rod 211 can easily pass through the inner cavities of both, thereby demolding the part in the inner cavity of the mold body 6.

[0035] Example 2

[0036] like Figure 1-3 As shown, in one embodiment, electric telescopic rods 8 are fixedly installed on the left and right sides of the top of the workbench 1. Clamping plates 9 are fixedly installed on the inner sides of the two electric telescopic rods 8. The inner sides of the two clamping plates 9 are attached to the outer side of the mold body 6. Moving grooves 10 are opened on the left and right sides of the top of the workbench 1. The bottom of the two clamping plates 9 is slidably connected to the inner cavity of the two moving grooves 10. A base plate 11 is fixedly installed on the bottom of the workbench 1. Anchor bolts 12 are threaded around the top of the base plate 11.

[0037] By setting the electric telescopic rod 8 and the clamping plate 9, the mold body 6 can be clamped, preventing the position of the mold body 6 from shifting during the stamping process, which would affect the normal operation of the stamping work. By setting the moving groove 10, the movement of the clamping plate 9 can be limited, preventing the clamping plate 9 from shifting during movement, which would lead to a decrease in the stability of clamping the mold body 6. By setting the anchor bolts 12, the overall equipment can be stabilized, preventing the equipment from tipping over due to accidental collisions, which would affect the stamping of automotive parts.

[0038] In operation, the following steps are taken: After the part to be processed is placed in the inner cavity of the mold body 6, the extension of the electric telescopic rod 8 causes the clamping plate 9 to fix the mold body 6 inward. Then, the downward extension of the hydraulic telescopic cylinder 4 causes the stamping device 5 to stamp the part in the inner cavity of the mold body 6. After stamping, the hydraulic telescopic cylinder 4 drives the stamping device 5 to move upward, and the output of the motor 202 causes the rotating plate 203 to rotate, which in turn drives the connecting rod 204 to flip. As the connecting rod 204 flips, the sliding block 205 moves outward, and the connecting rod 206 and the first clamping plate 207 move outward synchronously. At this time, the movable rod 208 flips and pushes the second clamping plate 209 upward. As the second clamping plate 209 moves, the top plate 210 and the push rod 211 both move upward and push the part in the inner cavity of the mold body 6 out, completing the demolding of the automobile part.

[0039] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
