Description

Technical Field

[0001] This utility model belongs to the field of injection mold technology, and relates to the sliding block feeding sprue fixing mechanism of the injection mold for the dual-color trim frame of automotive headlights. Background Technology

[0002] The dual-color headlight bezel is a component in automobiles, generally made of plastic. Most existing dual-color headlight bezels are mass-produced using injection molds. However, during the injection molding process, the molds used for these bezels tend to cause the plastic part to tilt, resulting in a smaller ejection area and range, and a less than ideal ejection effect.

[0003] A search revealed a sliding block ejector mechanism for a two-tone headlight trim frame injection mold, disclosed in patent publication number CN216708243U. This invention includes a lower injection mold and an upper injection mold. The upper injection mold has a flow divider at its top and a molding upper plate at its bottom. The lower injection mold has a sprue forming auxiliary component. During injection molding, the lower and upper injection molds are brought close together, ensuring the sprue forming auxiliary component fits snugly against the molding upper plate, forming a complete cavity. Molten material is injected into the cavity from the flow divider, completing the injection process. After injection, the mold is opened, and a multi-directional sliding block ejector assembly is moved. This assembly simultaneously ejects the upper and lower parts of the two-tone headlight trim frame located at the sprue forming auxiliary component, resulting in comprehensive multi-directional ejection. The ejection area and range are large, the ejection effect is good, and the plastic part is prevented from tilting during ejection, resulting in good flatness.

[0004] Although the above solution utilizes a slider-feed sprue holder to secure the moving mold mechanism, it has shortcomings in other aspects of mold performance, such as heat dissipation of the mold and the moving mold mechanism. Using a traditional water pipe inserted into the inside of the moving mold mechanism can easily cause water vapor to be generated in the moving mold mechanism during the cooling process. Therefore, a slider-feed sprue holder to secure the moving mold mechanism for the injection mold of the dual-color trim frame of automotive headlights was designed. Summary of the Invention

[0005] The purpose of this utility model is to provide a sliding block feeding sprue locking mechanism for a two-color trim frame injection mold for automotive headlights, so as to solve the problems mentioned in the background art.

[0006] The objective of this utility model can be achieved through the following technical solution: a sliding block inlet sprue and moving mold mechanism for a dual-color trim frame injection mold for automotive headlights, comprising an upper mold body and a lower mold base with a moving mold mechanism, wherein the moving mold mechanism of the upper mold body is connected to the mold cavity of the lower mold base for mold closing. Multiple heat conduction channels are provided on one side of the lower mold base. A fan plate mounting beam is installed on one side of the lower mold base. A fan plate component is installed at the bottom end of the fan plate mounting beam. Multiple fan bodies are installed on one side of the fan plate component. A water inlet pipe and a water outlet pipe are provided on the top of the other side of the fan plate component. Multiple U-shaped water pipes are provided at the bottom end of the water inlet pipe. All of the multiple U-shaped water pipes are connected to the water outlet pipe. An air guide and air distribution plate is provided on the other side of the air panel.

[0007] In the aforementioned sliding block injection molding mechanism for a dual-color trim frame of an automotive headlight, the top of the upper mold body is provided with a mold top plate, and a sprue is installed at the center of the mold top plate. The bottom of the sprue has a sprue channel extending to the upper mold body's moving mold mechanism. This design allows molten plastic material to be poured into the sprue channel and then injected into the upper mold body's moving mold mechanism and the lower mold base cavity.

[0008] In the aforementioned sliding block injection sprue locking mechanism of the dual-color trim frame injection mold for automotive headlights, a condenser strip is wound around the surface of the injection channel, and water pipe connectors are provided at both ends of the condenser strip. This design facilitates better cooling of the injection channel, preventing the molten plastic material entering the mold cavity from becoming too hot, which could affect the subsequent cooling and molding time. It also prevents heat loss from high temperatures affecting the injection channel.

[0009] In the aforementioned injection mold sliding block sprue fixing mechanism for the dual-color trim frame of automotive headlights, a hollow protective cover is installed at the bottom end of the mold top plate. Two through holes are provided on one side of the protective cover to accommodate water pipe connectors. This design aims to provide good protection, not only reducing heat interference but also ensuring the water pipe connectors and condenser hoses maintain a proper posture.

[0010] In the aforementioned sliding block injection sprue fixing mechanism of the dual-color trim frame injection mold for automotive headlights, a one-way inlet valve is provided at one end of the water inlet pipe, and an inlet valve control valve is installed at one end of the one-way inlet valve; a one-way outlet valve is provided at one end of the water outlet pipe, and an outlet valve control valve is installed at one end of the one-way outlet valve. This arrangement facilitates better flow control of the incoming and outgoing water, ensuring sufficient flow time for the water in the U-shaped water pipe.

[0011] In the aforementioned injection mold mechanism for a dual-color trim frame of an automotive headlight, the air guide plate is located between the water inlet pipe and the air distribution plate, and a cold source is provided on the air guide plate. This arrangement aims to generate cool air for the air guide plate, further accelerating the cooling and molding time.

[0012] Compared with the prior art, the advantages of the sliding block inlet sprue fixing mold mechanism of the dual-color trim frame injection mold of the automotive headlight are as follows: by setting up a wind plate component, multiple fan bodies are installed on one side, and water inlet and outlet pipes are set on the top of the other side. Multiple U-shaped water pipes are set at the bottom of the water inlet pipe to connect to the water outlet pipe. The flow of air and water is used to achieve efficient heat dissipation and ensure the efficiency of cooling and molding. At the same time, a cold source is set on the air guide plate to generate cold air for the air guide plate, which further accelerates the cooling and molding time. Attached Figure Description
