Patent number: 11524437Abstract: Provided is an improved mold structure, including a first mold base, a second mold base and two controllers. The first mold base and the second mold base are operably aligned. When the first mold base and the second mold base are in an aligned state, a mold cavity is jointly framed. Two gas passages, a first mold core and a second mold core are provided. The first mold base is provided with a runner. Two ends thereof are respectively connected to a material tube and a mold cavity of a molding machine. The first and second mold cores are made of porous material. Vent pipelines thereof are connected to the respective gas passages. The two controllers are respectively connected to the gas passages, and control the gas in and out such that the pressure in different areas in the mold cavity reaches a predetermined value, thereby controlling the flow direction of the raw material in the mold cavity.Type: GrantFiled: March 11, 2021Date of Patent: December 13, 2022Assignee: RAYSPERT PRECISION INDUSTRIAL INC.Inventors: Shun-Fu Lin, Yu-Chang Su

Publication number: 20070236569Abstract: A car-use camera comprises: a monitor shell having a monitor lens on the outside thereof and a charge-coupled device on the inside thereof; and a motherboard shell having a motherboard having peripheral circuits on the inside thereof, wherein a transmission line is located to electrically connect the motherboard and the charge-coupled device and an image output line is additionally mounted on the motherboard. The large-sized motherboard is separable from the monitor shell so only the monitor shell located on the outside of the car body is affected by the heat. As a result, the lifetime of the car-use camera can be extended. Besides, only the monitor shell may be taken away when the car-use camera suffers from thievery. Consequently, the risk of being taken away can be reduced.Type: ApplicationFiled: March 31, 2006Publication date: October 11, 2007Inventor: Shun-Fu Lin
