Title: Injection molding machine
Inventor: NAKADA MASAHIDE
IPC: B29C45/76
Filed: 2020-10-21
Abstract: To provide an injection molding machine capable of suppressing molding defects caused by dimensional changes of a mold in heat and cool molding.SOLUTION: An injection molding machine 1 adjusts a mold temperature to a high temperature target temperature, and a mold is mold-clamped by extending a toggle link mechanism 14. A resin is injected into a cavity when the mold temperature is the high temperature target temperature and in an initial state of mold clamping while extending the toggle link mechanism 14. After injection of the resin into a cavity 83, the mold temperature is adjusted to reach a low temperature target temperature. When a mold clamping force F applied to the mold is obtained in a state of extending the toggle link mechanism 14, and the mold clamping force F is smaller than a high temperature mold clamping force F0 applied to the mold in the initial state of mold clamping, the mold is pressed in a molding direction by a molding force supplementation mechanism 20 so that the mold clamping force F becomes as same as the high temperature mold clamping force F0.SELECTED DRAWING: Figure 3

Abstract: To enhance, in a vehicular lighting fixture that includes a plurality of sets of light emitting elements and reflectors, the conspicuity of the lighting fixture even if a plurality of reflectors is placed within a space that has a narrow back-and-forth width.SOLUTION: A vehicular lighting fixture is configured such that a plurality of cylindrical reflective elements 42s that extends in the vertical direction is formed on a concaved surface C that has a surface shape, as a reflection surface 42a of each reflector 42, which directs light from each light emitting element 30 to the forehead side of a lighting fixture and reflects such light as light spreading in the horizontal direction and in the vertical direction. This enables a placement of the plurality of reflectors 42 in a space that has a narrow back-and-forth width. Moreover, by reflecting the light from each light emitting element 30 at the reflection surface 42a of each reflector 42 as light spreading in not only the horizontal direction but also the vertical direction, and reflecting the light as light further spreading in the vertical direction, the emitted light in the front-side direction of the lighting fixture is effectively prevented from becoming excessively bright.SELECTED DRAWING: Figure 3
