Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0030] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions therein can be combined with each other.

[0031] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not require further definition or explanation in subsequent drawings.

[0032] like Figure 1-5 As shown, this embodiment proposes a car cover stamping die with a guide structure, comprising a workbench 1, a U-shaped plate 2 is fixedly connected to the top of the workbench 1, and a stamping guide mechanism 3 is provided between the U-shaped plate 2 and the workbench 1;

[0033] The punching guide mechanism 3 includes a hydraulic cylinder 301, a movable plate 302, a lower mold 303, an upper mold 304, a through hole 306, a limiting rod 305, a connecting spring 307, a guide groove 309, a guide block 308 and a positioning assembly 3010. The hydraulic cylinder 301 is bolted to the inner top of the U-shaped plate 2, the movable plate 302 is fixedly connected to the telescopic end of the hydraulic cylinder 301, the lower mold 303 is bolted to the top of the workbench 1, and the upper mold 304 is arranged directly below the movable plate 302. A plurality of through holes 306 all pass through the movable plate 302. The limiting rod 305 is fixedly connected to the top of the upper mold 304 and is slidably connected to the through hole 306. The connecting spring 307 is sleeved on the periphery of the limiting rod 305. The guide groove 309 is opened on the inner two side walls of the U-shaped plate 2. The guide block 308 is fixedly connected to the two side walls of the movable plate 302 and is slidably connected to the guide groove 309. The positioning assembly 3010 is arranged on When in use, the automobile cover plate to be stamped is placed on the top of the lower mold 303 between the mold 304 and the lower mold 303, and then the hydraulic cylinder 301 is started to drive the movable plate 302 to move downward. The movable plate 302 will drive the guide block 308 to move along the trajectory of the guide groove 309, thereby guiding the moving trajectory of the movable plate 302. At the same time, the movable plate 302 will drive the upper mold 304 to move downward. At this time, the upper mold 304 and the lower mold 303 will cooperate to stamp and shape the automobile cover plate, and then the limit rod 305 will move along the through hole 306. At this time, the connecting spring 307 will be compressed, which can reduce the impact force of the hydraulic cylinder 301. By setting the positioning component 3010, the upper mold 304 and the lower mold 303 can be positioned during their use to avoid misalignment between the upper mold 304 and the lower mold 303.

[0034] like Figure 4As shown, the positioning assembly 3010 includes positioning columns 30101 and positioning holes 30102. Multiple positioning columns 30101 are fixedly connected to the bottom of the upper mold 304. The positioning holes 30102 are opened at the top of the lower mold 303 and are plugged into the positioning columns 30101. When the upper mold 304 and the lower mold 303 cooperate to stamp and shape the automobile cover plate, the upper mold 304 will drive the positioning columns 30101 to be plugged into the positioning holes 30102 on the lower mold 303, so that the upper mold 304 and the lower mold 303 can be positioned during the use process of cooperation to avoid misalignment between the upper mold 304 and the lower mold 303.

[0035] like Figure 1 As shown, an I-shaped buffer block 4 is provided between the movable plate 302 and the upper mold 304. The top of the I-shaped buffer block 4 is fixedly connected to the bottom of the movable plate 302, and the bottom of the I-shaped buffer block 4 is fixedly connected to the top of the upper mold 304. When the upper mold 304 and the lower mold 303 cooperate to stamp and shape the automobile cover plate, the upper mold 304 is subjected to force and moves along the through hole 306 through the limiting rod 305. At the same time, the I-shaped buffer block 4 between the upper mold 304 and the movable plate 302 will be squeezed, thereby playing an auxiliary buffering role.

[0036] like Figure 5 As shown, the interior of the through hole 306 is fixedly connected with a guide sleeve 5 used in conjunction with the limiting rod 305, which can protect the limiting rod 305 and the passage to avoid wear between the limiting rod 305 and the through hole 306 due to long-term work.

[0037] like Figure 1 As shown, both side walls of the U-shaped plate 2 are fixedly connected with storage boxes 6, which are convenient for placing the staff's personal belongings or tools, thereby improving convenience.

[0038] like Figure 1 As shown, the upper mold 304 and the lower mold 303 have the same size. The upper mold 304 and the lower mold 303 are used in conjunction with each other, which can ensure that the upper mold 304 and the lower mold 303 are used in conjunction with each other normally, thereby improving the stability of the mold closing process.

[0039] like Figure 1 and Figure 5 As shown, the guide sleeve 5 and the I-shaped buffer block 4 are both made of synthetic rubber, which has excellent wear resistance and good weather resistance, thereby increasing the service life of the guide sleeve 5 and the I-shaped buffer block 4.

[0040] Specifically, when the automobile cover stamping die with a guide structure is used: first, the automobile cover plate is placed on the top of the upper die 304, and then the hydraulic cylinder 301 is started to drive the movable plate 302 to move downward, and the movable plate 302 will drive the guide block 308 to move along the track of the guide groove 309, so as to guide the moving track of the movable plate 302. At the same time, the movable plate 302 will drive the upper die 304 to move downward. At this time, the upper die 304 and the lower die 303 cooperate to stamp and shape the automobile cover plate, and then the limit rod 305 will move along the through hole 306. At this time, the connecting spring 303 is connected to the upper die 304. 07 will be compressed, which can reduce the impact force of the hydraulic cylinder 301. When the upper mold 304 and the lower mold 303 cooperate to stamp and shape the automobile cover plate, the upper mold 304 will drive the positioning column 30101 to plug into the positioning hole 30102 on the lower mold 303, so that the upper mold 304 and the lower mold 303 can be positioned during the coordinated use process to avoid misalignment between the upper mold 304 and the lower mold 303. Finally, the hydraulic cylinder 301 is started to drive the movable plate 302 to move upward, so that the upper mold 304 and the lower mold 303 are separated, and then the automobile cover after stamping and shaping is taken out.

[0041] All technical features in this embodiment can be freely combined according to actual needs.

[0042] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the scope of protection of the present invention.
