DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] Example 1

[0040] See also Figure 1 - Figure 7The present invention provides a technical solution: a stamping die for automobile parts, comprising a lower die base 100, a cavity plate 101 is arranged above the lower die base 100, an upper die base 102 is arranged above the lower die base 100, and a punching head is arranged on the lower surface of the upper die base 102, and a brushing mechanism 200 for brushing the cavity of the cavity plate 101 is arranged on the front surface of the lower die base 100. The mold can spray a release agent on the inner wall of the cavity before the plate-shaped workpiece 103 is stamped and evenly dry it, which can reduce the adhesion and friction between the stamping part and the inner wall of the cavity, thereby reducing the deformation of the stamping part during demolding, improving the demolding quality of the stamping part, and reducing the trouble and danger of manual application. The brushing mechanism 200 includes a frame 202 located outside the cavity plate 101, a spraying component 203 is arranged at the inner end of the frame 202, a drying component 204 is arranged on the upper surface of the frame 202, and a moving component 205 is arranged on the lower surface of the outer end of the frame 202;

[0041] The spraying component 203 includes a material storage box 2031 embedded in the frame 202, and the material storage box 2031 stores diluted demoulding agent. A plurality of spray heads 2032 are vertically arranged at the inner end of the frame 202, and a brushing plate 2033 is arranged outside the spray head 2032. After demoulding the inner wall of the mold cavity, the demoulding agent is evenly applied by the brushing plate 2033 to facilitate demoulding of the stamping part.

[0042] The drying component 204 includes a gas cylinder 2041 installed on the upper surface of the frame 202, a clamp for fixing the gas cylinder 2041 is arranged on the upper surface of the frame 202, an extension pipe 2043 is arranged on the outer side of the drying component 204, the rear end of the extension pipe 2043 extends to the rear end of the frame 202, so that the gas can act on the inner wall of the mold cavity when it is ejected, and a connecting pipe is arranged between the two, a movable rod 2042 is arranged inside the gas cylinder 2041, a piston plate is arranged inside the gas cylinder 2041, and the inner end of the movable rod 2042 is fixed to the surface of the piston plate;

[0043] The movable member 205 includes a rack 2055 horizontally fixed on the lower surface of the frame 202, and a gear 2056 is meshed below the rack 2055. The two can drive the frame 202 to move forward and backward, making it convenient for the spraying member 203 to spray the cavity on the surface of the cavity plate 101.

[0044] In this embodiment, preferably, an electric cylinder 2034 is vertically arranged on the inner side of the material storage box 2031. The electric cylinder 2034 can be used to change the height of the brushing plate 2033, which is convenient for extending into the mold cavity to brush the inner wall. The brushing plate 2033 is a brush plate, which is convenient for evenly brushing the release agent. The lower end of the electric cylinder 2034 is connected to the brushing plate 2033, and a feeding pipe is arranged between the nozzle 2032 and the material storage box 2031, so that the release agent in the material storage box 2031 can be sprayed out through the feeding pipe and the nozzle 2032.

[0045] In this embodiment, preferably, a plurality of nozzles 2044 are arranged on the lower surface of the extension tube 2043 along its length direction, a push plate 2045 is vertically sleeved on the free end of the movable rod 2042, a lifting cylinder 2046 is arranged on the upper end of the push plate 2045, and the lifting cylinder 2046 is vertically installed on the surface of the upper mold base 102. When the lifting cylinder 2046 is working, it can drive the frame 202 to move up and down, thereby changing the height position of the spray component 203.

[0046] In this embodiment, preferably, the movable component 205 also includes a bottom rail 2051 arranged on the lower surface of the frame 202, and a guide sleeve 2052 is sleeved on the bottom rail 2051, and the two are slidably connected to facilitate the movement of the frame 202, and a telescopic column 2053 is vertically arranged on the lower surface of the guide sleeve 2052, and the telescopic column 2053 can support the frame 202, and a supporting cross plate 2054 is arranged between the two telescopic columns 2053 to facilitate the installation of the drive motor 2057, and a base 201 for installing the telescopic column 2053 is arranged on the front surface of the lower mold base 100, and a driving motor 2057 connected to the gear 2056 is arranged on the upper surface of the supporting cross plate 2054, and the driving motor 2057 can drive the gear 2056 to rotate, thereby driving the rack 2055 meshing with the gear 2056 to move.

[0047] In summary, before the plate-like workpiece 103 is punched, the driving motor 2057 works to drive the gear 2056 to rotate, and the gear 2056 rotates to drive the rack 2055 meshing therewith to move backward, driving the frame 202 and the bottom rail 2051 to move in the guide sleeve 2052. When the frame 202 moves backward to a suitable position, the demoulding agent in the storage box 2031 is sprayed out through the feed pipe and the nozzle 2032, and acts on the inner wall of the mold cavity. The brushing plate 2033 brushes the inner wall of the mold cavity as the frame 202 moves, and the sprayed demoulding agent is evenly applied. As the frame 202 moves backward, it drives the gas cylinder 2041 to move backward, allowing the internal piston plate to move forward, squeezing out the gas inside the gas cylinder 2041 and extending the gas cylinder 2041. The tube 2043 and the nozzle 2044 spray out, and the sprayed gas acts on the inner wall of the mold cavity to accelerate the drying of the release agent on the inner wall. After drying, the driving motor 2057 reverses to drive the gear 2056 to reverse, and the rack 2055 meshing with it moves forward, and the air cylinder 2041 moves forward to exhaust air, which is convenient for spraying again. When the frame 202 moves forward to the outside of the stamping die, the driving motor 2057 stops working, and the frame 202 moves back and forth. After the stamping part is demolded, the frame 202 pushes the demolded stamping part to be unloaded. During the unloading process of the stamping part, the release agent will not be sprayed. The brushing mechanism 200 can reduce the friction resistance and adhesion between the stamping part and the mold cavity, facilitate the demolding of the stamping part, and reduce deformation after demolding.

[0048] Example 2

[0049] Reference Figure 8, which is the second embodiment of the present invention.

[0050] In this embodiment, preferably, a blanking component 400 is provided at the rear side of the cavity plate 101. By providing the blanking component 400, it can guide and collect the stamped parts when the plate-like workpiece 103 is blanked after being stamped, and after each stamped part is blanked, foam particles are added to the blanking box 401, so that the next stamped part will not collide with the previous stamped part, thereby increasing the safety of stamping part blanking. The blanking component 400 includes a blanking box 401 located at the rear of the cavity plate 101, and two partition plates 403 are vertically arranged inside the blanking box 401. The partition plates 403 divide the blanking box 401 into a storage space in the middle for collecting stamped parts and a filling space on both sides filled with foam particles. The surface of the partition plates 403 is open. A notch is provided to facilitate the discharge of foam particles from the notch, a rotating baffle 404 is rotatably arranged at the notch, a rotating motor for driving the rotating baffle 404 is arranged on the surface of the partition plate 403, and the rotating baffle 404 is driven by the rotating motor to rotate to expose the notch, a guide plate 402 is tiltedly arranged on the front side of the discharge box 401, and an adjusting cylinder 405 connected to the side of the discharge box 401 is arranged on the rear surface of the lower die base 100, and the positions of the discharge box 401 and the guide plate 402 can be changed by the adjusting cylinder 405, so that the discharge box 401 and the guide plate 402 can be moved close to the cavity plate 101, which is convenient for the discharge of stamping parts, and during stamping, the discharge box 401 and the guide plate 402 can be moved outward again without affecting the stamping process of the stamping die.

[0051] In summary, after the plate-like workpiece 103 is stamped, the stamped part is separated from the die cavity upwards and is pushed toward the blanking member 400 by the movable frame 202. At this time, the adjusting cylinder 405 works, and the internal piston rod retracts, driving the blanking box 401 and the guide plate 402 to move toward the cavity plate 101. The stamped part is pushed by the frame 202 and falls on the guide plate 402, and falls into the blanking box 401 along the guide plate 402. At this time, the rotating motor works, driving the rotating baffle 404 to rotate, and the partition plate 403 is moved. The notch on the stamping part is exposed, allowing the foam particles in the filling space to enter the storage space from the notch and cover the stamping part, playing a barrier role when the next stamping part is unloaded, so that the adjacent stamping parts will not be directly contacted and collided to cause deformation, thereby improving the stamping quality of the stamping parts. After the stamping parts are unloaded, the adjusting cylinder 405 works again, and the internal piston rod extends to drive the unloading box 401 and the guide plate 402 to move outward away from the cavity plate 101, which does not affect the stamping die to stamp the plate workpiece 103 again.

[0052] Example 3

[0053] Reference Fig. 9 and Fig.10 , which is the third embodiment of the present invention.

[0054] In the present embodiment, preferably, a feeding mechanism 300 is provided on the left side of the lower die base 100. The feeding mechanism 300 can play a guiding role when the plate-like workpiece 103 is fed and stamped, and can press the plate-like workpiece 103 during stamping to avoid deformation or arching of the plate-like workpiece 103 during stamping, thereby increasing the stamping stability of the plate-like workpiece 103 and improving the stamping quality. The feeding mechanism 300 includes a support plate 301 horizontally located on the outer side of the cavity plate 101, which supports and prevents the plate-like workpiece 103 from falling. The plate-like workpiece 103 extending to the upper surface of the cavity plate 101 is placed above the support plate 301, and two frames 302 are provided on the lower surface of the support plate 301. The frames 302 are fixed on the mounting surface to support the support plate 301, and the upper surface of the support plate 301 is provided with guide components 303 relatively located on both sides of the plate-like workpiece 103.

[0055] In this embodiment, preferably, the guide member 303 includes a fixed rail 3031 fixed horizontally on the upper surface of the support plate 301, and a guide wedge block 3032 for guiding the plate-like workpiece 103 is arranged above the inner end of the fixed rail 3031. The inner side surface of the guide wedge block 3032 is in contact with the side surface of the plate-like workpiece 103 to play a guiding role. A movable wedge block 3033 is in contact with the outer side of the guide wedge block 3032, and a pressing plate 3034 for pressing the upper surface of the plate-like workpiece 103 is arranged on the outer side of the movable wedge block 3033. The pressing plate 3034 contacts the plate-like workpiece 103 and can fix the plate-like workpiece 103 by using the clamping force and friction resistance, so that the plate-like workpiece 103 will not be arched or moved, which is convenient The plate-like workpiece 103 is stamped, and a moving cylinder 3035 is arranged above the outer end of the fixed rail 3031, and the inner end of the moving cylinder 3035 is connected to the outer side of the moving wedge 3033, and the two are slidably connected. A sliding groove is provided on the outer side of the moving wedge 3033, and a sliding block extending into the sliding groove is arranged at the inner end of the moving cylinder 3035, and a return spring is arranged between the lower surface of the sliding block and the lower end of the sliding groove. The sliding cooperation between the two will not allow the moving wedge 3033 to be separated from the piston rod, and the moving wedge 3033 can be moved up and down. The bottom of the moving cylinder 3035 and the guide wedge 3032 are both provided with a sliding seat 3036 mounted on the fixed rail 3031, which is convenient for the movement of the moving cylinder 3035 and the guide wedge 3032.

[0056] In summary, when in use, the plate-like workpiece 103 can be placed on the support plate 301 and located between the two guide wedge blocks 3032. As the plate-like workpiece 103 is fed, the side surface of the plate-like workpiece 103 contacts the inner surface of the guide wedge block 3032. When the plate-like workpiece 103 moves to a suitable length, the moving cylinder 3035 works, and the internal piston rod extends to drive the moving wedge block 3033 to move, so that the moving wedge block 3033 fits with the guide wedge block 3032. As the moving wedge block 3033 fits, it gradually moves downward, and the return spring is gradually compressed and generates a reverse return elastic force, and the moving wedge block 3033 moves. It will drive the pressure plate 3034 to move downward to contact the plate-like workpiece 103, fix the position of the plate-like workpiece 103, and prevent it from moving or arching during the stamping process, thereby increasing the stamping stability of the plate-like workpiece 103. After the stamping is completed, when the plate-like workpiece 103 is fed again, the moving cylinder 3035 works, and the internal piston rod retracts, driving the moving wedge block 3033 to move outward without the restriction of the guide wedge block 3032. The reset spring restores its elasticity, driving the moving wedge block 3033 and the pressure plate 3034 to move upward and away from the plate-like workpiece 103, making it convenient for the plate-like workpiece 103 to be fed again.
