Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, and in particular to a stamping die for a car taillight housing. Background Art

[0002] The car taillight is an important lighting device at the rear of the vehicle, which can alert the rear vehicles and improve visibility. The shell of the car taillight is generally processed by stamping. This method can quickly complete the processing and manufacturing of large quantities. A transparent shell will be installed on the outside of the car taillight, and lighting beads are also arranged inside the car taillight to achieve the purpose of lighting.

[0003] In the prior art, when stamping the automobile taillight housing, it is generally processed in the form of a punch and a die, and the raw material is placed on the top of the die. The punch stamps the die. At this time, the raw material will enter the interior of the die under the influence of pressure. Due to the large force generated during the stamping process, the raw material is impacted, which will cause the raw material to be too close to the die. During the collection process, it will be inconvenient to take it. If the tool is warped, it will cause certain damage to the finished product. Utility Model Content

[0006] With the above solution, the lower die is connected to the base by bolts, which is convenient for installation and removal of the die. When the die needs to be replaced or repaired, the lower die can be easily removed by loosening the bolts, and the lifting assembly arranged inside the base can effectively extrude the material inside the lower die, making the stamping parts more smoothly when demolding, reducing the scrap rate caused by poor demolding.

[0012] By adopting the above scheme, the pedal body is rotatably connected to the inside of the base, so that the operator can easily operate the entire jacking structure by stepping on the pedal body, and through the coordinated use of auxiliary wheels and chains, the position of the lock hook can be more flexibly controlled, thereby conveniently controlling the jacking structure through the pedal.

[0013] As a preferred embodiment of the above technical solution, the upper top of the rising plate is symmetrically fixedly connected with a fixed bracket, and the two locking hooks are respectively rotatably connected to the second set of rods and the middle part of the fixed bracket.

[0015] As a preferred embodiment of the above technical solution, the upper top of the top plate is symmetrically fixedly connected with a hydraulic push rod, the telescopic end of the hydraulic push rod is fixedly connected with a load-bearing plate, the telescopic end of the hydraulic push rod passes through the top plate, and the lower bottom end of the load-bearing plate is bolted with an upper convex mold that cooperates with the lower concave mold.

[0016] By adopting the above scheme, the telescopic end of the hydraulic push rod can drive the load-bearing plate and the upper punch to move, thereby cooperating with the lower die to complete the stamping work, and the bolt-type connection method can quickly replace the upper punch.

[0017] As a preferred embodiment of the above technical solution, the load-bearing plate is slidably connected to a plurality of fixing rods.

[0018] By adopting the above solution, the sliding connection between the fixing rod and the load-bearing plate can guide the load-bearing plate during use, thereby achieving more stable operation.

[0019] Compared with the prior art, the beneficial effects of the utility model are:

At this time, the material will extend out of the lower die after being pushed upward, and in this way, the material can be quickly taken out to a certain extent. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] like Figure 3 and Figure 4 As shown, the jacking assembly includes a jacking structure and a pedal structure arranged inside the base 1, the jacking structure includes a guide rod 31 symmetrically fixedly connected to the inside of the base 1, the outer wall of the guide rod 31 is movably sleeved with a protective sleeve 32, the outside of the protective sleeve 32 is fixedly connected with a rising plate 3 to protect the rising plate 3 and ensure that the rising plate 3 always moves in a straight line, the upper top of the rising plate 3 is symmetrically fixedly connected with a push rod 33, the upper top of the push rod 33 passes through the interior of the base 1 and is located at the inner bottom end of the lower die 16, the end of the push rod 33 is flush with the inner bottom end of the lower die 16 so as not to affect the extrusion of the finished product and to achieve a corresponding ejection effect.

[0029] like Figure 3 and Figure 4 As shown, the pedal structure includes a pedal body 2 rotatably connected to the inside of the base 1, an outer groove 22 is symmetrically opened at the end of the pedal body 2, and a second set of rods 23 is fixedly connected to the inner wall of the outer groove 22, and a first set of rods 21 is symmetrically fixedly connected to the inside of the base 1, and an auxiliary wheel 26 is symmetrically and movably sleeved on the outer wall of the first set of rods 21, and a chain 25 is wrapped around the outer wall of the auxiliary wheel 26 so that the auxiliary wheel 26 can assist the chain 25 to work and make it respond quickly, and locking hooks 24 are fixedly connected to the two ends of the chain 25, and a fixed bracket 34 is symmetrically fixedly connected to the upper top of the rising plate 3, and the two locking hooks 24 are respectively rotatably connected to the middle part of the second set of rods 23 and the fixed bracket 34, so that the rising plate 3 can be driven to move upward through the chain 25. When the pedal body 2 loses pressure, the rising plate 3 will drive the chain 25 to reset due to gravity and reset the pedal body 2.

[0030] like Figure 1 and Figure 2 As shown, the upper top of the top plate 13 is symmetrically fixedly connected with a hydraulic push rod 14, the telescopic end of the hydraulic push rod 14 is fixedly connected with the load-bearing plate 12, the telescopic end of the hydraulic push rod 14 passes through the top plate 13, and the lower bottom end of the load-bearing plate 12 is bolted with an upper punch 15 that cooperates with a lower concave die 16, so as to achieve the purpose of quick disassembly, thereby replacing different molds, and the load-bearing plate 12 is slidably connected with a plurality of fixed rods 11.
