Description

Technical Field

[0001] This utility model relates to the technical field of tailgate lower trim panel injection molding system, specifically to a novel tailgate lower trim panel injection molding system. Background Technology

[0002] The tailgate trim is a decorative or functional component installed on the inside or outside of the bottom of the tailgate (trunk door). It is usually made of plastic, composite materials or metal. Most tailgate trims are covered with a layer of velour to enhance their visual and tactile appeal.

[0003] In existing technology, the production of the lower tailgate trim panel of a car typically begins with injection molding a single piece of plastic as the main material. During the injection molding process, reinforcing ribs and clips are then injected onto this single piece of plastic. After cooling and solidification, the entire panel is removed from the injection molding machine and transported to the next station for surface and edge treatment. The panel is then transported to the next station where a velour fabric is applied to its surface. Finally, the panel is transported to the next station for trimming, completing the production of the lower tailgate trim panel.

[0004] The production method for this type of tailgate trim panel involves many steps, is time-consuming, and has low production efficiency.

[0005] Therefore, it is necessary to provide a production system with fewer processes and higher production efficiency. Utility Model Content

[0006] This application provides a novel injection molding system for the lower tailgate trim panel, which solves the technical problems of multiple processes and low efficiency in the production system of the lower tailgate trim panel.

[0007] This application provides a novel tailgate lower trim panel injection molding system, comprising: a three-in-one injection molding machine, a preheating box for heating sheet metal, a first robotic arm for transporting velvet material, and a second robotic arm for transporting sheet metal; the three-in-one injection molding machine includes a fixed mold, a moving mold, and an injection molding device; the fixed mold is provided with a first mounting part for placing velvet material; the moving mold is provided with a second mounting part for placing sheet metal; the moving mold and the fixed mold are closed to stamp the velvet material and sheet metal, and the injection molding device is located in the moving mold and is used for injection molding on the sheet metal; the opening of the preheating box faces the initial position of the moving mold, and the preheating box is located on one side of the three-in-one injection molding machine.

[0008] By adopting the above technical solution, and replacing the injection molding process of the lower tailgate trim panel with a pre-formed sheet, production efficiency is greatly improved. Furthermore, the three-in-one injection molding machine integrates the stamping and injection molding of materials, further reducing production steps and improving production efficiency. In addition, a preheating box is set up to preheat the sheet, enhancing the bonding strength between the molten plastic and the sheet during the injection molding process. While ensuring the strength of the lower tailgate trim panel, production efficiency is further improved.

[0009] Preferably, the maximum injection pressure output by the injection molding device is 16.2 MPa.

[0010] By adopting the above technical solution, the precise injection pressure control of 16.2MPa can ensure that the molten plastic fully fills the mesh molding groove, and prevent the sheet from being damaged due to excessive pressure.

[0011] Preferably, the other side of the three-in-one injection molding machine is equipped with a conveyor belt for transporting finished materials.

[0013] Preferably, a novel tailgate lower trim panel injection molding system also includes a third robotic arm for transporting finished materials from a three-in-one injection molding machine to a conveyor belt.

[0014] By adopting the above technical solution and setting up a third robotic arm to transport materials and products, the system's automation and production efficiency are improved.

[0015] Preferably, the fixed mold has multiple recessed molding cavities arranged vertically, and the moving mold has multiple protruding pressing blocks arranged vertically. When the moving mold and the fixed mold are closed, each pressing block presses the velvet material and the sheet into the corresponding molding cavity.

[0016] By adopting the above technical solution, multiple mold cavities and pressure blocks arranged vertically can be used to simultaneously complete the molding of multiple products in a single mold closing, thereby significantly improving production efficiency.

[0017] Preferably, each pressure block surface is provided with a mesh-like molding groove, and each mesh-like molding groove is provided with multiple injection ports at intervals, and each injection port is connected to an injection molding device.

[0018] By adopting the above technical solution, the mesh-distributed molding grooves, combined with the spaced injection ports, allow the molten plastic to spread evenly along the mesh path. Multi-point injection reduces the time required for injection molding and improves production efficiency.

[0019] Preferably, the moving mold moves horizontally, and the first mounting part includes multiple first hanging pins, with the multiple first hanging pins in groups of three, and each group of first hanging pins is spaced apart above each molding cavity.

[0020] By adopting the above technical solution and combining it with the horizontal mold closing mode of the three-in-one injection molding machine, the first hanging needle pierces the fleece material for fixation, optimizing the time required for the fleece material to be fixed and further improving production efficiency.

[0021] Preferably, the moving mold moves horizontally, and the second mounting part includes multiple second pins, which are arranged in groups of three, with each group of two pins spaced above each pressure block.
