Description

Technical Field

[0001] This utility model relates to the field of automotive molds, and in particular to a continuous blanking mold for a shock absorber mounting plate that can be used on both sides. Background Technology

[0002] The shock absorber mounting plate is a crucial component of the automotive suspension system, bearing the heavy responsibility of connecting the shock absorber to the vehicle body. It is typically made of high-strength steel or aluminum alloy, possessing excellent strength and durability. The mounting plate features precisely positioned mounting holes and fixing structures, ensuring the shock absorber is securely installed and effectively absorbs and cushions the impact of road bumps during vehicle operation, improving ride comfort. Simultaneously, it significantly contributes to the stability of the vehicle body structure, helping to disperse vibrations and impacts, reducing damage to other vehicle components, and extending the overall lifespan of the vehicle. Utility model patent application CN201220253078.0 discloses a stamping die for processing automotive shock absorber mounting plates. This stamping die has a single-core structure, capable of stamping only the left or right mounting plate, resulting in low efficiency. Furthermore, the die lacks a mold-closing guide function, which is detrimental to ensuring stamping accuracy. It also lacks a detection mechanism for whether the material is properly placed, requiring visual inspection to determine placement, which can easily lead to misjudgments and affect stamping quality. Utility Model Content

[0004] The technical solution of this utility model is as follows: a continuous blanking mold for a shock absorber mounting plate, comprising an upper mold base, a lower mold base, and a buffer mold base; the buffer mold base is slidably fitted inside the lower mold base, and each of the four corners of the lower mold base is provided with a hanging shaft. An elastic support member, which is a gas spring, is provided between the buffer mold base and the lower mold base. A lower left mold core and a lower right mold core are arranged side by side in the middle of the buffer mold base, and the two mold cores are symmetrically arranged. Both the lower left mold core and the lower right mold core are boss-shaped. A higher left mold core and a higher right mold core are arranged side by side in the middle of the upper mold base, and the two mold cores are symmetrically arranged. Both the upper left mold core and the upper right mold core are groove-shaped. The size of the concave mold matches the size of the convex mold and can be interlocked. An L-shaped locating pin is provided on the outer side of both the lower left mold core and the lower right mold core. A guide slope is provided on the inner side of the locating pin. A feeding detection mechanism is provided between the L-shaped locating pins. A clearance groove for the detection mechanism is provided in the upper mold base. When the mold is closed, the feeding detection mechanism can be matched and fitted into the clearance groove.

[0005] Preferably, the feeding and detection mechanism includes a base plate, a U-shaped frame, an inner swing arm plate, and an outer swing arm plate. The base plate is fixed to the assembly groove on the lower mold base by high-strength screws. The U-shaped frame is vertically fixed to the base plate. A horizontal shaft is provided at both the upper and lower parts of the U-shaped frame. A connecting rod is hinged to the upper part of the U-shaped frame and connected to the upper horizontal shaft. The upper part of the inner swing arm plate is hinged to the connecting rod. A guide slope is provided on the outer side of the upper part of the inner swing arm plate. The outer swing arm plate is hinged to the lower part of the U-shaped frame and is hinged to the lower horizontal shaft. The lower end of the inner swing arm plate is hinged to the tip of the outer swing arm plate. The inner swing arm plate is triangular in shape. A photoelectric switch corresponding to the end of the outer swing arm plate is provided on the base.

[0006] Preferably, the U-shaped frame has a horizontal plate in the middle, a column head in the middle of the horizontal plate, and a column head in the middle of the inner swing arm plate. A return spring is connected between the middle of the inner swing arm plate and the horizontal plate, and the return spring is fitted between the two column heads.

[0007] Preferably, both ends of the side of the lower mold base are provided with guide rods, which are vertically and fixedly connected to the lower mold base. The guide rods are slidably inserted into the sliding sleeves provided on the side of the buffer mold base, and the sliding sleeves are embedded and fixed in the buffer mold base.

[0008] Preferably, both the upper left mold core and the upper right mold core are provided with sliding holes. There are two sliding holes, which are symmetrically arranged at both ends of the mold core. The upper mold base is provided with a telescopic push rod mechanism. The push rod in the telescopic push rod mechanism is fitted into the sliding hole, and the end of the push rod is arc-shaped.

[0009] Preferably, a two-stage guide mechanism is provided between the two ends of the upper mold base, the lower mold base, and the buffer mold base.

[0010] Preferably, the two-stage guiding mechanism includes a first slide table provided on the bottom surface of the upper mold base end, a second slide table provided on the end surface of the buffer mold base, and a first guide groove provided on the end of the lower mold base. The inner side of the first guide groove is provided with a supporting slider, and the second slide table is provided with a second guide groove.

[0011] The beneficial technical effects of this utility model are: This mold integrates the left and right mounting plate mold cores of the shock absorber into one mold. Only one mold is needed to achieve the stamping of the left and right mounting plates, which can effectively improve the production efficiency of the mounting plates. Furthermore, a two-stage guide mechanism is set between the upper and lower mold bases and the middle buffer mold base. The guide mechanism provides guidance for the mold closing stamping, thereby improving the stamping accuracy and quality of the mounting plates.

[0012] The mold is equipped with a feeding detection mechanism. When the sheet is placed in the lower left or lower right mold core, the edge of the sheet will contact the guide slope of the inner swing arm plate in the detection mechanism, driving the lower end of the inner swing arm plate to swing outward, causing the outer swing arm plate to flip so that its outer end blocks the photoelectric switch. The photoelectric switch is triggered to send a signal that the sheet is in place, avoiding misjudgment caused by visual observation. Attached Figure Description

[0015] Example 1, see appendix Figure 1-24. A continuous blanking die for a shock absorber mounting plate, comprising an upper die base 1, a lower die base 2, and a buffer die base 3; the buffer die base 3 is slidably fitted inside the lower die base 2, and an elastic support is provided between the buffer die base and the lower die base to allow the buffer die base 3 a certain sliding allowance within the lower die base 2; a left lower die core 21 and a right lower die core 22 are arranged side by side in the middle of the buffer die base 3, the two die cores being used to place the left and right mounting plates of the shock absorber, respectively; both the left and right lower die cores are boss-shaped, and their dimensions match those of the shock absorber mounting plates; the upper die base 1... The upper left mold core 11 and the upper right mold core 12 are arranged side by side in the middle. Both the upper left mold core 11 and the upper right mold core 12 are groove-shaped and can be fitted into the upper mold core with a boss-shaped shape. The outer side of the lower left mold core 21 and the lower right mold core 22 are provided with a ring of L-shaped positioning pins 25. The L-shaped positioning pins provide a limit for the sheet material and make it accurately placed on the lower mold core. A feeding detection mechanism 4 is provided between the L-shaped positioning pins 25. The upper mold base 1 is provided with a corresponding clearance groove 13 for the detection mechanism. When the mold is closed, the feeding detection mechanism 4 fits into the clearance groove 13 to avoid conflict.

[0016] Guide rods 31 are provided at both ends of the side of the lower mold base 2. The guide rods 31 are slidably fitted into the sliding sleeves 32 provided on the side of the buffer mold base 3. The guide rods 31 provide guiding support for the pressure movement of the buffer mold base 3, thereby improving its movement accuracy.

[0017] Lower mold inserts 23 are evenly distributed between the lower left mold core 21, the lower right mold core 22 and the lower mold base 2. The lower mold inserts 23 improve the assembly firmness between the lower mold core and the lower mold base 2. Upper mold inserts 15 are evenly distributed between the upper left mold core 11, the upper right mold core 12 and the upper mold base 1. The upper mold inserts 15 improve the assembly firmness between the upper mold core and the upper mold base 1. At the same time, upper pads 16 are provided on the edge of the surface of the upper mold base 1 and lower pads 24 are provided on the edge of the surface of the buffer mold base 3 to protect the mold base.

[0018] Both the upper left mold core 11 and the upper right mold core 12 have sliding holes inside. The upper mold base 1 has a corresponding telescopic push rod mechanism inside. The push rod 14 in the telescopic push rod mechanism is fitted into the sliding hole. After the mold closing and stamping are completed, the telescopic push rod mechanism drives the push rod 14 to extend out of the sliding hole and push against the surface of the workpiece. Then the upper mold base 1 rises to separate the upper and lower mold cores, preventing the upper mold core from lifting the workpiece and ensuring safety.

[0019] In this embodiment, the mold cores of the left and right mounting plates of the shock absorber are integrated into one mold. Only one mold is needed to achieve the stamping and forming of the left and right mounting plates, which can effectively improve the production efficiency of the mounting plates.

[0020] Example 2, see appendix Figure 2-35-6, this embodiment is basically the same as embodiment one, and the similarities will not be repeated. The difference is that the feeding and detection mechanism 4 includes a base plate 41, a U-shaped frame 42, an inner swing arm plate 43, and an outer swing arm plate 44. The base plate 41 is fixed in the assembly groove 45 provided on the lower mold base 2. The U-shaped frame 42 is vertically fixed to the base plate 41. A connecting rod 46 is hinged to the upper part of the U-shaped frame 42, forming a double-rod structure, which has the advantage of high stability under force and swing. The inner swing arm plate 43... The upper part is hinged to the connecting rod 46, which rotates from the top to pull the inner swing arm plate 43. A guide slope 431 with a smooth surface is provided on the outer side of the upper part of the inner swing arm plate. The outer swing arm plate 44 is hinged to the lower part of the U-shaped frame 42. The lower end of the inner swing arm plate 43 is hinged to the tip of the outer swing arm plate 44. After the inner swing arm plate 43 is subjected to force and rotates, it can drive the outer swing arm plate 44 to swing. A photoelectric switch 47 with a size corresponding to the end of the outer swing arm plate 44 is provided on the base. In addition, a guide plate 411 is vertically provided on the base plate 41. A guide notch 412 is provided in the middle of the guide plate 411. The outer swing arm plate 44 fits into the guide notch 412.

[0021] A horizontal plate 48 is provided in the middle of the U-shaped frame 42. A return spring 49 is connected between the middle of the inner swing arm plate 43 and the horizontal plate 48. The return spring generates an elastic support force in the middle of the inner swing arm plate 43.

[0022] The principle of the feeding and inspection mechanism 4 is as follows: When the sheet metal is placed into the lower left mold core 21 or the lower right mold core 22, the L-shaped positioning pins 25 around it provide guidance for the workpiece, so that it is accurately placed on the surface of the mold core. During this process, the edge of the sheet metal will contact the guide slope 431 of the inner swing arm plate 43. The resulting top pressure drives the lower end of the inner swing arm plate 43 to swing outward, thereby driving the outer swing arm plate 44 to flip, so that its outer end blocks the photoelectric switch 47. The photoelectric switch 47 is triggered to send a signal that the sheet metal is placed in place, avoiding misjudgment caused by visual observation, and thus avoiding the phenomenon of cracks on the surface of the sheet metal due to uneven force, ensuring stamping quality.

[0023] Example 3, see appendix Figure 1 This embodiment is basically the same as Embodiment 1, and the similarities will not be repeated. The difference is that a two-stage guide mechanism 5 is provided between the upper mold base 1, the lower mold base 2 and the buffer mold base 3. The two-stage guide mechanism 5 includes a first slide 51 provided on the bottom surface of the end of the upper mold base 1, a second slide 52 provided on the end surface of the buffer mold base 3 and a first guide groove 53 provided on the end of the lower mold base 2. The second slide 52 is provided with a second guide groove 54. The first slide 51 can slide into the second guide groove 54 and the second slide 52 can slide into the first guide groove 53.

[0024] When the blanking die is closed and stamped, the first slide 51 at the end of the upper die base 1 matches and enters the second guide groove 54 of the second slide 52, and slides down along the second guide groove 54. After moving to the ground of the second guide groove 54, it pushes the second slide 52 to move down. The second slide 52 slides down in the first guide groove 53, providing guidance for the closing process of the upper die base 1, lower die base 2 and buffer die base 3, avoiding the phenomenon of slight misalignment of the die core due to the stamping pressure, and improving the stamping accuracy and quality of the mounting plate.
