Description

Technical Field

[0001] The present application relates to the technical field of guard plate mold frames, and in particular to a rear door guard plate mold frame. Background Art

[0002] Guardrails are a type of safety facility used to protect people and prevent accidents. They are widely used in roads, bridges, buildings, factories, etc. The main function of guardrails is to prevent pedestrians, vehicles and other objects from falling from heights or running off the road, thereby reducing the possibility of accidents.

[0003] When embossing guardrails in three dimensions, the embossing molds on most equipment are fixed on the equipment and are not easy to replace, making the equipment unsuitable for the production and processing of a variety of patterns, resulting in reduced functionality of the equipment and reduced work efficiency. When embossing guardrails, the guardrails will be under pressure. If the pressure is too great, the probability of deformation and damage of the guardrail will increase, resulting in reduced equipment utilization efficiency and increased use costs.

[0004] In response to the above technical problems, the patent number CN214492326U discloses a three-dimensional embossing device for guardrails, which relates to the technical field of guardrail processing equipment, including an embossing device, the embossing device includes an outer guard plate, the outer guard plate includes a connecting rod, the top end of the side of the connecting rod is fixedly connected to an upper plate, the bottom surface of the upper plate is fixedly installed with an embossing machine, the bottom surface of the connecting rod is fixedly connected to a workbench, and the upper surface of the workbench is fixedly connected to a bottom plate. The utility model rotates the threaded rod on the threaded groove and cooperates with the connection between the ring plate and the threaded rod to separate the ring plate from the locking head, and then uses the connection between the sliding rod and the locking head to remove the ring plate and the embossing plate for replacement, thereby avoiding the problem that the embossing mold on most equipment is fixed on the equipment and is not easy to replace, making the equipment unsuitable for the production and processing of a variety of patterns, resulting in reduced functionality of the equipment and reduced work efficiency, thereby achieving the effect of improving the functionality and work efficiency of the equipment.
