Description

Technical Field

[0001] This invention relates to the field of low-pressure injection molding technology, and more specifically to a deformation-resistant automotive pillar injection molding equipment. Background Technology

[0002] Low-pressure overmolding is a process in interior parts production where fabrics such as cloth, leather, and velvet are first fixed to the inner wall of the mold cavity using mold pins. Then, plastic raw materials are injected under low pressure and low temperature, allowing the melt to penetrate and adhere from the back of the fabric. The finished product is cooled and molded as a single piece. The finished fabric and substrate are firmly bonded, with a smooth, wrinkle-free surface and a soft, delicate feel. It eliminates the need for a manual overmolding process, is highly efficient, environmentally friendly, and odorless, and is widely used in the production of soft interior parts such as automotive door panels, pillars, and headliners.

[0003] Chinese patent CN119820797B discloses a low-pressure injection mold for automobile manufacturing, specifically relating to the field of injection mold technology. It includes a fixed mold and a moving mold, with the moving mold positioned on one side of the fixed mold. An ejector pin is located inside the fixed mold, and a guide post is located on one side of the fixed mold. The surface of the guide post is slidably connected to the inner wall of the moving mold. An injection cavity is located on one side of the moving mold, and a cutting device is also located on one side of the moving mold. This device separates the residual molten plastic inside the injection cavity from the molten plastic inside the mold cavity, and pushes the cooled molten plastic out of the moving mold. This allows for more complete filling of the mold cavity by the molten plastic, reducing the likelihood of residual molten plastic in the injection cavity connecting with the molded parts inside the cavity after cooling and solidification, thus preventing the formation of excess columnar protrusions on the surface of the parts that require secondary removal. This improves the molding quality and processing efficiency of plastic products. However, this device still has the following problems. When it is necessary to cover the injection molding, the device requires manual fixation of the covering cloth to the inside of the device through the positioning slot pin. After production is completed, manual entry into the mold is also required to remove the molded workpiece.

[0004] Based on this, the present invention designs a deformation-resistant automotive column injection molding equipment to solve the above problems. Summary of the Invention

[0016] In this invention, the covering fabric released from the feeding mechanism 2 enters between two clamping frames 334. After a certain length is released, the feeding mechanism 2 stops unwinding. Then, the two first push cylinders 333 drive the two clamping frames 334 and the second moving frame 332 to limit and slide, clamping the covering fabric. At the same time, the first tensioning rod 342, the second tensioning rod 345, and the transverse tensioning rod 348 all clamp the covering fabric synchronously. Then, the feeding mechanism 2 cuts the covering fabric. After cutting, the first tensioning push cylinder 341 drives the first tensioning rod 342 to move down and tension the upper half of the covering fabric vertically. Then, the second tensioning push cylinder 344 pushes the second tensioning rod 345 to move down and tension the lower half of the covering fabric vertically. Then, the second tensioning rod 345 drives the transverse tensioning rod 348 through the first inclined surface 346 and the second inclined surface 347 to move laterally under the limitation of the third slider rail limiting assembly 349, tensioning the covering fabric horizontally. After tensioning, the multi-axis...

Then, the overhead track trolley 322 drives the first moving frame 31 to move through the L-shaped connecting plate 323 and the linear module 324 to press the vacuum suction cup 336 against the injection-molded car pillar workpiece. Then, the vacuum suction cup 336 adsorbs the car pillar workpiece. After adsorption, the overhead track trolley 322 resets. Then, the first push cylinder 333 drives the clamping frame 334 to reset.
