Description

Technical Field

[0001] This utility model relates to the field of punching die technology, and in particular to a punching die for bonding fabric to the rear trim of a roof. Background Technology

[0002] The headliner rear trim fabric bonding and die-cutting die is a specialized die used in the production of automotive headliner rear trim parts. It is primarily used to bond fabric materials to a substrate (such as plastic or metal sheet) through a bonding process, while simultaneously cutting them into the required shape and size using a die-cutting process. This die is widely used in automotive interior manufacturing, especially in the production of headliners, doors, and other interior components, ensuring precise fabric bonding and shaping.

[0003] Patent document CN218283370U discloses a punching die translation mechanism and a punching die, including a base. The bottom of the base is provided with at least one recessed mounting groove. A rolling component is provided in the mounting groove to reduce the friction at the bottom. The base is also provided with a control component to control the rolling component to move up and down relative to the base. In the first state, the control component controls the rolling component to descend relative to the base and fixes the rolling component at a position beyond the mounting groove, so as to support the base upward and allow the punching die to move smoothly, making the translation operation of the punching die more labor-saving and convenient. In the second state, the control component removes the force on the rolling component, and the base descends due to its own weight, pushing the rolling component into the mounting groove so as not to interfere with the placement and installation of the punching die.

[0004] However, the existing headliner fabric bonding die requires cumbersome steps such as traditional bolt fixing during use, making it difficult to easily disassemble and assemble the die, and increasing the cycle of die replacement or maintenance. Utility Model Content

[0013] (III) Beneficial Effects This utility model provides a die for bonding and cutting fabric for the rear trim of a roof, which has the following advantages: 1. The fabric of the rear trim piece of the roof fits the punching die. Through the setting of the limiting component and the fixed box, when it is necessary to disassemble or install the upper or lower die, press the sliding plate, so that the sliding plate slides inside the fixed box. Then the sliding plate squeezes the support spring, so that the support spring is compressed by force. At the same time, one end of the insert rod slides in the groove on the sliding plate, so that the locking block disengages from the locking groove on the insert rod. This pulls the upper or lower die, so that the insert rod disengages from the inside of the fixed box. This achieves the effect of convenient disassembly and assembly of the die, avoiding the cumbersome steps of traditional bolt fixing, and significantly shortening the die replacement or maintenance cycle.

[0014] 2. The fabric of the rear roof trim is attached to the punching die. By setting the push component, during punching, the upper die presses down, so that the rear roof trim is attached to the surface of the lower die. At the same time, the top plate slides down inside the lower die, so that the two ends of the transmission rod rotate on the movable bolt and the sliding seat respectively, thereby pushing the sliding seat to slide on the surface of the sliding rod. When the sliding seat moves in the slide groove, it squeezes the telescopic springs on both sides, so that the telescopic springs are deformed and generate elastic force. When the upper die moves up, the telescopic spring pushes the sliding seat, thereby pushing the top plate to push the rear roof trim out, thus avoiding the workpiece from being deformed or scratched due to vacuum adsorption or residual stress adhering to the die surface.
