Abstract: Provided is a mold core structure, which is arranged on a mold.

Abstract: 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.

Abstract: Provided is a mold structure with a fast replacement of a mold core, including an upper mold base and a lower mold base corresponding to the upper mold base. The upper mold base is provided with at least one upper mold base, wherein the bottom of the upper mold base is provided with a push-pull device, the push-pull device includes a pressure cylinder and a push-pull rod capable of expansion and contraction and the upper mold core is driven by the expansion and contraction of the push-pull rod, and is relatively separated from or embedded in the upper mold base, and wherein the bottom of the upper mold core is provided with a chute, and the upper mold core is operatively coupled with or separated from the push-pull rod by the chute. Consequently, the action of replacing the mold core is performed.

Abstract: Provided is a liquid silicone molding die, including a first mold base, having at least one first molding zone and a feed hole on one side thereof and having a feeding mechanism coupled to the feed hole on the other side thereof, wherein the feeding mechanism is coupled to an injection machine to inject a raw material, and a heating element is provided around the first molding zone; and a second mold base, operatively facing or separating from the first mold base, corresponding to the side of the first mold base and correspondingly provided with a second molding zone, an injection channel, a sealing ring groove and a sealing ring.

Abstract: Provided is an injection molding device, including an injection port arranged on an upper mold base; an upper mold arranged in the upper mold base, wherein at least one ejection port, a gasket groove and a gasket are provided and the ejection portion is connected to the injection port; a lower mold base operatively aligned with or separated from the upper mold base and provided with at least one gas passage for the gas to enter or exit; and a lower mold disposed on the lower mold base. The lower mold base is aligned with or separated from the upper mold base, the lower mold is provided with a mold cavity and at least one shaped air path is provided to connect the mold cavity with the gas passage. The lower mold is a porous material and has a plurality of pores. Gas is pre-injected into the mold cavity through the gas passage and at least one air path to maintain a preset pressure inside the mold cavity.

Abstract: A side alarm for vehicles has a post mounted in a front side of the vehicle; and at least one monitor mounted on the post. In usage, the monitor can be pivoted manually and is connected to a screen in the vehicle. When the monitor is switched on, the monitor can shoot the scene outside of the vehicle. The scene of the monitor is transferred to display on the screen in the vehicle so that a driver can monitor the road condition by the screen to avoid the car accident.

Abstract: 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.
