Description

Technical Field

[0001] The utility model relates to the technical field of windshield wiper strip production, in particular to an extrusion die for an automobile windshield wiper strip. Background Technique

[0002] A windshield wiper, also known as a wiper, windshield wiper, or windscreen wiper, is a device used to scrape raindrops and dust attached to the vehicle's windshield to improve the driver's visibility and increase driving safety. Due to legal requirements, almost all cars are equipped with windshield wipers, and the rear windows of hatchbacks and SUVs are also equipped with windshield wipers. In addition to cars, other transportation tools are also equipped with windshield wipers, such as trains and trams. Some engineering tools, such as cranes, are also equipped with windshield wipers. A windshield wiper is a tool for simply cleaning the front glass of a motor vehicle to prevent rainwater and other contaminants from affecting the line of sight. The existing patent, patent publication number CN220429219U, discloses an extrusion die for an automobile windshield wiper strip, which relates to the technical field of extrusion dies, and solves the problem that the die head of the existing extrusion die does not have a quick switching structure and can only be installed with a die head of one specification. Therefore, when the die head needs to be replaced, the installation and disassembly operations of the die head are required, and the steps are cumbersome, and it cannot adapt to the alternating extrusion processing of different specifications of rubber strips. It includes: a die module, the die module is inserted on the side of the switching disk; the switching disk can rotate on the side of the fixed frame, so that the use position of the die module can be switched. Thus, through the cooperation of the die module at different positions and the material channel, it is possible to switch the processing specifications without disassembling the die module, which is convenient to use. At the same time, under the action of the control column, the use position of the switching disk can be locked and adjusted, and the use is stable.

[0003] Regarding the above related technologies, the inventor believes that there are the following defects: in the actual application process, although the adjustment and locking operations are performed on it, when replacing the switching disk, it is not convenient to perform the disassembly and assembly operations, thereby reducing the use convenience of the die and reducing the use efficiency of the die. Therefore, we propose an extrusion die for an automobile windshield wiper strip to solve the above problems. Content of the Utility Model
