AI Technical Summary
In the existing technology, the edge wrapping process of the backing layer of car seat cushions relies on manual operation, which leads to low production efficiency, poor product quality consistency, safety risks, and high labor costs.
Design an automated mold that integrates hot pressing, folding, and pressing functions. Through the coordinated action of pressing cylinders and folding cylinders, the edge of the coating layer is automatically bent and pressed. Combined with the design of contour blocks and hot air channels, the tight fit between the coating layer and the structural component is ensured.
It improved the production efficiency and product quality consistency of seat cushions and backrest covers, reduced labor intensity and scrap rate, and achieved efficient and low-cost large-scale production.

Abstract
Claims
1. A cushion back cover mold characterized by comprising: It includes an upper mold assembly and a lower mold assembly; the upper mold assembly includes an upper contour block, the lower surface of which has a contour of the back of the backrest structure; the lower mold assembly includes a lower contour block, the upper surface of which has a contour groove for the front of the backrest structure. The upper mold assembly includes an upper fixed plate and a support plate. The support plate is fixed between the fixed plate and the upper contour block. At least one edge-pressing cylinder is fixedly connected to the support plate. The movable end of the edge-pressing cylinder is connected to the edge-pressing block. The edge-pressing block is located at the edge of the upper contour block, and the lower part of the edge-pressing block is the contour of the inner side of the backrest structure. An air passage is opened inside the upper contour block. The air inlet of the air passage is connected to a hot air blower, and the air outlet of the air passage is located at the edge of the upper contour block. The aforementioned lower mold assembly includes a lower fixed plate. Folding cylinders are provided on the lower fixed plate at positions corresponding to the pressing cylinders. An folding block is fixedly connected to the movable end of the folding cylinder. The folding block has a contouring structure for the edge of the backrest structure on the side near the lower contour block.
2. The cushion back cover mold according to claim 1, wherein, The lower side of the pressing block is provided with a first inclined surface, and the folding block is provided with a second inclined surface corresponding to the first inclined surface.
3. The cushion and back cover mold of claim 2, wherein, A slot or block is provided below the upper contour block.
4. The cushion and back cover mold of claim 3, wherein, The lower mold assembly is provided with at least two folding cylinders and two folding blocks; the two folding cylinders and folding blocks are distributed on opposite sides of the lower contour block; each folding block has a groove on the side away from the lower contour block, through which a U-shaped frame is set, and a clamping cylinder is rotatably installed in the U-shaped frame; a pressure plate is provided on the side of the folding block near the lower contour block; a connecting rod is provided between the clamping cylinder and the pressure plate; one end of the connecting rod is rotatably connected to the clamping cylinder, and the other end of the connecting rod is fixedly connected to the pressure plate; a support rod is also provided on the folding block; the support rod is located in the middle of the connecting rod and is rotatably connected to the connecting rod; driven by the clamping cylinder, the pressure plate can be raised or lowered.
5. The cushion and back cover mold of claim 4, wherein, The lower fixed plate is also provided with at least two telescopic cylinders, and the movable end of the telescopic cylinder is fixedly connected to a positioning pin.
