Description

Technical Field

[0001] The utility model relates to the technical field of light guide columns, in particular to a universal liquid light guide column silicone mold. Background Art

[0002] A silicone light guide mold is a specialized mold used to manufacture light guides, typically made from silicone. Silicone molds offer high-temperature resistance, corrosion resistance, and strong tear resistance, making them suitable for the production of various crafts and optical devices. When crafting a silicone light guide mold, factors such as mold size, design, and production process must be considered.

[0003] Usually, the light guide column mold consists of a frame, a mold core, a pouring system, a demoulding mechanism and a temperature control system. The pouring system pours the raw materials into the mold core, and the temperature control system adjusts the temperature of the mold. After the raw materials solidify, the demoulding mechanism ejects the formed workpiece.

[0004] However, since the design of the light guide column needs to consider the light transmission efficiency and uniformity, the parting line of the visible surface of the product is not taken into account in the design of the mold, which will lead to poor light guiding effect of the product and a high defective rate during production.

[0005] Based on this, the utility model designs a universal liquid light guide column silicone mold to solve the above problems. Utility Model Content

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solution: the mold core includes an upper template, a middle template and a lower template, the upper template is fixedly provided with a main channel, the middle template includes a fixed mold and a movable mold, a cavity is provided between the movable mold and the fixed mold, the main channel is connected to the cavity, the lower template is provided with a groove, the groove is matched with the bottom of the cavity, a slider is provided on the side of the movable mold, a slide rail is provided on the frame, and the movable mold is slidably connected to the frame.

[0007] By adopting the above technical solution, the pouring system injects the raw material into the cavity through the main channel. The top and bottom of the cavity are respectively composed of the upper template and the lower template. After the raw material is cooled and formed in the cavity, the upper template and the lower template are separated from each other, exposing the visible surface of the light guide column. After the visible surface is completely formed, the fixed mold and the movable mold are separated from the left and right, and the entire light guide column can be removed from the mold. The parting line will appear on the side of the light guide column to avoid affecting the integrity of the visible surface of the light guide column, thereby improving the light guiding effect of the light guide column and effectively reducing the defective rate of the product.

[0008] Preferably, two movable molds are provided, and the movable molds are respectively located on both sides of the fixed mold. A plurality of branch runners are provided on the main channel, and the cavity is connected with the branch runners.

[0009] By adopting the above technical solution, the mold can form multiple products at one time, thereby improving the molding efficiency of the mold.

[0010] Preferably, a limiting groove is provided on the lower template, and the limiting groove is tightly pressed against the side of the mold core.

[0011] By adopting the above technical solution, the lower mold plate can further limit the merging between the movable mold and the fixed mold, thereby avoiding glue overflow during injection molding.

[0012] Preferably, a groove is provided on the movable mold, and when the movable mold is placed on the lower mold plate, two sides of the groove are tightly pressed against the lower mold plate.

[0013] By adopting the above technical solution, the lower mold plate and the movable mold can be matched more closely, so that the movable mold can be more stable when combined with the fixed mold.

[0014] Preferably, the groove is provided with an inclined surface, and the inclined surface cooperates with the lower template.

[0015] By adopting the above technical solution, the upper and lower sliding of the lower mold plate and the movable mold becomes smoother, which reduces jamming and scratching, ensures the quality of the mold and improves production efficiency.

[0016] To sum up, the present application has the following beneficial technical effects: by adopting the above-mentioned technical scheme, the pouring system injects raw materials into the cavity through the main channel, and the top and bottom of the cavity are respectively composed of the upper template and the lower template. After the raw material is cooled and formed in the cavity, the upper template and the lower template are separated up and down, exposing the visible surface of the light guide column. The visible surface is completely formed, and then the fixed mold and the movable mold are separated left and right, and the entire light guide column can be removed from the mold. The parting line will appear on the side of the light guide column to avoid affecting the integrity of the visible surface of the light guide column, thereby improving the light guiding effect of the light guide column and effectively reducing the defective rate of the product.
