This invention relates to the field of silicone rubber materials technology, specifically to a wide-temperature-range pressure-heated silicone rubber material for automobiles and its preparation method. The automotive wide-temperature-range pressure-heated silicone rubber material comprises the following raw materials: by weight, 40-60 parts liquid silicone rubber, 30-50 parts phase change energy storage system, 3-8 parts damping reinforcing filler, 2-5 parts antifreeze modifier, 1-3 parts silane coupling agent, 1-3 parts flame retardant synergist, and 0.5-1.5 parts platinum catalyst. The automotive wide-temperature-range pressure-heated silicone rubber material prepared by this invention possesses pressure-triggered self-heating characteristics, along with wide-temperature-range stability, excellent damping and vibration reduction performance, and compliance with safety standards.

This invention relates to the field of rail transit signaling equipment technology, specifically disclosing an LED signal controller and its usage method. The LED signal controller of this invention includes a base and at least two light boxes. All the light boxes are stacked and connected sequentially from top to bottom, with the center of all the light boxes aligned on a central line. The connection between each pair of adjacent light boxes is a square sleeve structure. A rubber ring is interference-fitted between the upper and lower light box connection parts. Spring washers are disposed on the top of the base. By using a square sleeve structure with interference-fitted rubber rings between adjacent light boxes, the center of all the light boxes is aligned on a central line, completely solving the problem of easy turning with circular sleeves, while simultaneously achieving waterproofing, dustproofing, and vibration resistance. The spring washers between the base and the light boxes effectively absorb vibration, preventing bolt loosening, and the self-locking latch ensures a tight lock on the door cover, further improving overall sealing and vibration resistance.

This invention relates to the field of stamping die technology and discloses a bidirectional slide rail side-cutting system for separating display screen front frame products from waste materials. The system includes: an upper die assembly and a lower die assembly, which are capable of relative opening and closing; at least one set of side-cutting units disposed on the lower die assembly, each set of side-cutting units including: a slide rail assembly slidably mounted on the lower die assembly for supporting the product to be stamped and flexibly pressing it; a cutting punch mounted on the slide rail assembly for performing the stamping action; and at least one set of drive components. This invention cleverly decomposes and converts the longitudinal stamping force of traditional stamping dies into transverse side-cutting force through the inclined surface cooperation between the drive components and the slide rail assembly. This force conversion makes the stamping action smoother, avoiding the deformation risk caused by longitudinal impact on thin-walled products, and solving the problem of unstable product dimensions from a mechanical perspective.
