This utility model discloses a high-efficiency venting structure for die-casting molds, relating to the field of mold technology. It includes: a fixed mold and a moving mold; the fixed mold has a cavity at the top center, and the moving mold has a mold base fixedly installed at the bottom, inserted into the cavity; a venting groove is located at the bottom center of the mold base, and a venting hole penetrating the mold base and the moving mold is located at the top of the venting groove; a venting assembly is located inside the venting groove; and a cooling assembly is fixedly installed at the top of the venting pipe. This utility model achieves automatic venting, preventing molten metal leakage and ensuring venting efficiency. It also extends the flow path of high-temperature gas within the venting stack. Combined with circulating cold water and heat dissipation fins in the water tank, it can quickly absorb gas heat, reduce the venting temperature, prevent direct venting of high-temperature gas from scalding operators, and reduce the impact on the workshop environment temperature.

The utility model discloses a dust-free bin film pasting device with an upper cover easy to tear and paste and a suit, the film pasting device comprises a bottom plate and a film pasting bin arranged on the inner surface of the bottom plate, and the film pasting bin is used for containing a film assembly and an electronic product; the bottom plate is provided with a head end and a tail end, the head end of the bottom plate is convexly provided with a positioning column on the outer side of the film pasting bin, and the positioning column is used for being clamped with a film assembly during film pasting; the outer surface, deviating from the film pasting bin, of the bottom plate is provided with a finger pressing position and an easy-to-tear pasting position; the finger pressing position is arranged close to one side of the head end, the easy-to-tear pasting position is arranged close to one side of the tail end, and a pasting hole communicated with the film pasting bin is formed in the position, at the easy-to-tear pasting position, of the bottom plate. When the film pasting device is used for pasting films on products such as mobile phones and tablet personal computers, air trapping caused by the fact that the whole tempered film makes contact with a display screen in advance is avoided.

The utility model relates to injection mold technical field discloses a kind of injection mold with automatic exhaust device, including bottom plate, the outside fixed connection of bottom plate has lower mould holder, the outside fixed connection of lower mould holder has multiple guide pillars, the outside fixed connection of guide pillar has upper mould holder, the bottom fixed connection of upper mould holder has mould core, the outside fixed connection of mould core has multiple positioning rods, the outside fixed connection of bottom plate has exhaust mechanism, the inside fixed connection of lower mould holder has driving mechanism;The exhaust mechanism includes mould cavity, the outside fixed connection of mould cavity is in the outside of lower mould holder. In the utility model, positioning rod is moved by mould core, so that servo plate drives tension spring to move, then vacuum pump drives suction pipe to move, so that injection mold realizes automatic exhaust, can accurately discharge cavity gas, and enhances production stability and intelligent level.
