Description

Technical Field

[0001] The utility model relates to the technical field of sealing strip punching, in particular to a punching die for automobile sealing strips. Background Art

[0002] Automobile sealing strips are important automobile parts and are mainly used in doors, bodies, sunroofs, trunks and other parts. They have sealing functions such as sound insulation, dustproof, windproof and waterproof. They can also buffer the body parts when the body vibrates slightly, and can effectively prevent the glass and other parts from shaking, so as to improve the service life of other automobile parts and the riding comfort. In addition, they can also absorb the dimensional tolerances and assembly tolerances generated during the automobile production process. According to the use parts, sealing strips can be divided into glass guide grooves, door outer sealing strips, door opening sealing strips, outer pressure strips, inner pressure strips, luggage compartment strips, sunroof strips and other types. After the automobile sealing strips are produced, they need to be punched into a certain length by a punching die.

[0003] The prior art (publication number: CN 212123577 U) discloses a punching die for automobile sealing strips, comprising a mounting plate, a rubber strip guide groove arranged on the mounting plate and two punching dies, the two punching dies are arranged at both ends of the rubber strip guide groove, the punching die comprises a bottom plate, a punching bottom die and a bracket arranged on the bottom plate, and a cylinder arranged on the bracket, the piston rod end of the cylinder is connected with a punching knife, the punching bottom die is arranged below the punching knife, the top of the punching bottom die is provided with a punching opening adapted to the punching knife, the punching bottom die is provided with a through sealing strip through-opening, and the sealing strip through-opening corresponds to the notch of the rubber strip guide groove.

[0004] Although the cutting length and cutting angle of the above patent are stable, both ends of the product are punched and formed at one time, and the punched products can be directly inspected, packaged and put into storage, which reduces waste generation and saves production costs. However, there are the following disadvantages: when punching, no other operation steps are required, and it is necessary to wait until the punching is completed before loading and taking materials, etc. can be performed, which easily wastes time and affects work efficiency. Further improvement is needed. For this reason, we propose a punching mold for automobile sealing strips. Utility Model Content

[0005] The main purpose of the utility model is to provide a die for punching automobile sealing strips, which can effectively solve the problems in the background technology.

The specific structure is: the pushing component 10 includes a horizontal plate 101, and the horizontal plate 101 is installed at the left end of the bracket 7. A cylinder 102 is installed at the upper end of the horizontal plate 101. The output end of the cylinder 102 movably passes through the lower end of the horizontal plate 101 and is transmission-connected with a pushing rod 103, and the pushing rod 103 is used to push the sealing strip.

[0028] In order to improve the rotation stability of the circular plate 21 , an annular groove 13 is formed on the inner wall of the circular groove 12 , and a guide ring 24 is located in the annular groove 13 .

[0029] The left ends of the two lower molds 3 both have discharge ports 4 for convenient placement of the sealing strip. The discharge ports 4 extend to the right ends of the lower molds 3. The upper ends of the two lower molds 3 both have a plurality of punching grooves 5 distributed in a linear array. The two lower molds 3 are both mounted on the upper ends of the circular plate 21.

[0030] A through slot 11 is provided at the lower end of the bottom plate 1 , and the through slot 11 extends to the upper end of the bottom plate 1 . The through slot 11 is used to facilitate the automobile sealing strip that has been punched to fall out of the punching die.
