Description

Technical Field

[0001] This utility model relates to the field of rabbit-shaped light guide cover mold technology, and in particular to a rabbit-shaped light guide cover mold structure. Background Technology

[0002] The mold base is the fundamental component supporting the entire mold structure, typically used to secure mold cores, mold cavities, and other parts. Mold bases are usually made of high-quality alloy steel or steel plates, possessing characteristics such as high strength, wear resistance, and pressure resistance. Molds are tools used in industrial production to shape products; their fundamental knowledge covers structural composition, design elements, and manufacturing principles. Core content includes mold classification, component functions, and the influence of shape, involving fields such as injection molding and structural optimization. Molds mainly consist of components such as the front mold (fixed mold), rear mold (moving mold), inserts, slides, and ejector pins.

[0003] In an existing type of rabbit-shaped light guide cover mold structure, when workers cooperate with the mold during actual operation and processing, the mold body is mostly connected by a single force, which affects the mold expansion and the processing quality of the product. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a rabbit-shaped light guide cover mold structure.

[0005] This utility model is achieved by the following technical solution: a rabbit-shaped light guide cover mold structure, including a bottom mold plate, a mounting column fixedly connected to the top of the bottom mold plate, and a positioning column fixedly connected to the top of the bottom mold plate; An outer mold 1 is inserted into the top of the bottom mold plate. A cooling pipe 1 is fixedly connected inside the outer mold 1. An inner mold 1 is fixedly connected inside the outer mold 1. A connecting support is fixedly connected to the top of the outer mold 1. An outer mold 2 is inserted into the top of the connecting support. An inner mold 2 is inserted into the inside of the outer mold 2. A cooling pipe 2 is fixedly connected inside the inner mold 2. An injection pipe is fixedly connected inside the inner mold 2. A sealing top plate is inserted into the top of the outer mold 2. A positioning support ring is fixedly connected inside the sealing top plate.

[0006] With the above technical solution, the bottom mold plate serves as the basic platform, with ample operating space around it to facilitate the insertion / removal of mold components. The mounting column also serves as a lifting lug, simplifying the handling of large molds.

[0007] As a further improvement to the above solution, the number of mounting columns and buffer springs is set to four, with each pair forming a group, and the four mounting columns and buffer springs are symmetrically distributed with the bottom mold plate as the center.

[0008] As a further improvement to the above solution, an outer mold is inserted into the top of the mounting column, and a cooling pipe is fixedly connected inside the inner mold. The top of the inner mold is in contact with the bottom surface of the inner mold.

[0009] With the above technical solution, cooling pipe one is built into inner mold one, and cooling pipe two is integrated into inner mold two. The two can be independently temperature controlled and can be repaired separately in case of failure, reducing downtime.

[0010] As a further improvement to the above solution, the top of the outer mold one is in contact with the bottom surface of the outer mold two, and the top of the outer mold two is in contact with the bottom surface of the sealing top plate.

[0011] Through the above technical solution, the outer mold 1 is symmetrically distributed around the connecting pillar, which supports the quick insertion and removal of the outer mold 2 and the inner mold 2, and adapts to the production needs of light guide covers with different shapes.

[0012] As a further improvement to the above solution, an injection pipe is fixedly connected inside the positioning support ring, the injection pipe is inserted into the inside of the sealing top plate, and the second cooling pipe is fixedly connected inside the second inner mold.

[0013] As a further improvement to the above scheme, the number of connecting pillars is set to four, and two pillars are grouped together. The four connecting pillars are symmetrically distributed around the mold as the center.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention uses a positioning support ring to fix the injection pipe, ensuring that the molten resin is injected along the central axis, avoiding bubbles or cold lines caused by flow deviation. The sealing top plate contacts the top of the second outer mold, forming a closed high-pressure environment and improving the filling density. By setting the top of the first outer mold to contact the bottom of the second outer mold and connecting the support columns in series, a segmented clamping force distribution is achieved, reducing the risk of mold expansion in deep cavity structures.

[0015] This invention reduces light scattering loss and improves the light transmittance of the light guide by setting the inner mold surface to be polished with high precision. The double-layer mold structure isolates external impurities and ensures the cleanliness of the optical surface. By setting the injection tube at the center of the positioning support ring and using a tangential injection port, the melt is guided to spirally fill the cavity, avoiding air entrapment and weld lines, and improving the uniformity of light guiding.

The cooling pipe 11 is fixedly connected to the inside of the inner mold 10. By setting the surface of the inner mold to be polished with high precision, light scattering loss is reduced and the light transmittance of the light guide is improved. The double-layer mold structure isolates external impurities and ensures the cleanliness of the optical surface. By setting the injection tube 12 to be located at the center of the positioning support ring 14 and using a tangential injection port, the melt is guided to spirally fill the cavity, avoiding air entrapment and weld lines, and improving the uniformity of light guiding.

[0027] The number of connecting pillars 8 is set to four, and they are grouped into two groups. The four connecting pillars 8 are symmetrically distributed around the center of mold 5.
