This utility model discloses a three-section structure for the lower mold of a wheel hub mold, including: a lower mold for the wheel hub, a lower mold section body provided on the inner cavity of the lower mold through a mold base, a lower mold section water-cooling insert for the lower mold section body which is fixed with bolts for disassembly and replacement, and a lower mold section cold water insert for the lower mold section which is fixed with screws for disassembly and replacement. Through the independent water-cooling structure of the lower mold section cold water insert, the cooling efficiency of the original weak heat dissipation area can be enhanced, the local temperature can be reduced quickly, and the segmented water cooling makes the temperature distribution of each area more balanced, reducing the thermal deformation of the mold caused by temperature difference and improving the quality of wheel hub forming. The lower mold section two and three both adopt the insert structure fixed with bolts / screws. When a certain section or the easily corroded third section is worn or corroded, it is not necessary to disassemble or replace the entire lower mold, but only to replace the corresponding insert, which greatly reduces maintenance costs and downtime.

The application provides an LCD black-and-white screen projection lighting structure, which is mainly composed of a projection assembly, a light funnel and a light source rotating disc. The light source rotating disc is designed to rotate around the central axis, so as to reduce the local temperature rise of the light source rotating disc. A plurality of color source areas are arranged in the circumferential direction on the light source rotating disc. The light outlet of the light funnel is opposite to the projection assembly, and the light inlet is opposite to the color source area on the light source rotating disc, so that the light loss in the transmission process is minimized. The light emitted by the color source area is efficiently collected by the light funnel and transmitted to the projection assembly, so that the light utilization rate is improved. The rotation of the light source rotating disc enables the color source areas to work alternately, so that the local high temperature caused by long-time light irradiation in a single area is avoided, and good heat dissipation effect is achieved. Meanwhile, the color source areas are independently lighted, only the working color source area generates heat, the overall heat generation is reduced, and the temperature is lowered.

This invention relates to the field of automotive parts processing technology, specifically disclosing an injection molding device for the production of plastic automotive trim parts. The device includes an injection molding material block and an injection molding block, with the injection molding block positioned above and in contact with the injection molding material block. The injection molding material block has a feed inlet. The device also includes an air removal mechanism; the air removal mechanism includes a blower, a recessed block, a moving tube, air removal components symmetrically arranged on both sides of the moving tube, a drive component for driving the moving tube to reciprocate along the length of the recessed block, a chamber on the injection molding material block, and an air inlet on the moving tube. The blower and the recessed block are both fixedly connected to the chamber; the moving tube is slidably connected to the recessed block. The air removal components include an air supply pipe, a sliding hole on the chamber, a through hole on the moving tube, and an air supply hole on the air supply pipe; the sliding hole communicates with the feed inlet. This solves the problem of feed inlet blockage easily occurring after injection molding of the injection molding material in existing injection molding devices.

This invention provides a shampoo production device, including a raw material storage tank and a heating assembly for heating the raw material storage tank. A gas recovery mechanism is provided between the raw material storage tank and the heating assembly. The gas recovery mechanism includes a gas recovery pipe connected to the raw material storage tank, a gas recovery pump connected to the gas recovery pipe, and a gas diversion pipe located at the end of the gas recovery pipe away from the raw material storage tank. The gas diversion pipe includes a gas return section and a gas release section, both of which are connected to the gas recovery pipe. This invention reduces heating energy consumption in the production process by recovering and utilizing high-temperature hot gas. Furthermore, the high-temperature hot gas is ejected through the gas release section, increasing thermal convection, breaking down temperature stratification, and preventing localized excessively low temperatures during the heating process.
