Technical Field
[0001] The utility model belongs to the technical field of motorcycle headlight processing and relates to a precision injection mold for a motorcycle headlight cover. Background Art
[0002] During the production and processing of motorcycles, in order to improve the safety of motorcycles driving at night, a headlight structure needs to be installed on the front of the motorcycle. Among them, the motorcycle headlight cover is one of the important accessories of the headlight. The headlight cover effectively protects the bulb inside the headlight. The current motorcycle headlight cover is mainly formed by injection mold processing.
[0003] In the process of processing motorcycle headlight shades, we found that the cooling water pipe of the injection mold is only set inside the lower mold base, and the cooling water pipe is horizontally designed. Due to the arc-shaped structure design of the headlight shade, it is easy to cause uneven heat dissipation when the headlight shade is cooled and formed, affecting the molding efficiency of the headlight shade and thus affecting the processing efficiency of the headlight shade. For this reason, we designed a motorcycle headlight shade precision injection mold to solve the above technical problems. Summary of the Invention
[0004] The purpose of the utility model is to provide a precision injection mold for a motorcycle headlight cover, so as to solve the problem proposed in the above background technology that the cooling water pipe inside the traditional headlight cover injection mold is designed as a horizontal type. Due to the arc-shaped structure design of the headlight cover, it is easy to cause uneven heat dissipation during the cooling and molding of the headlight cover, thereby affecting the molding efficiency of the headlight cover.
[0005] The purpose of the utility model can be achieved through the following technical solutions: a precision injection mold for a motorcycle headlight cover, comprising a lower fixed plate and an upper fixed plate, support blocks are fixedly provided on both sides of the top of the lower fixed plate, and a lower mold base is fixedly installed on the top of the two support blocks, and an upper mold base adapted to the lower mold base is fixedly installed on the bottom end of the upper fixed plate, a plurality of water inlet pipes are equidistantly fixed on one side of the lower mold base and the upper mold base, a plurality of water outlet pipes are equidistantly fixed on the other side of the lower mold base and the upper mold base, a plurality of cooling water pipes are equidistantly fixed inside the lower mold base and the upper mold base, and the plurality of cooling water pipes are distributed in an arc shape, and the plurality of cooling water pipes are connected to the water inlet pipes and water outlet pipes that are aligned with each other. The purpose of this setting is to achieve synchronous cooling of the top and bottom of the headlight shade by arranging cooling water pipes inside the upper mold base and the lower mold base, thereby improving the molding efficiency of the headlight shade. At the same time, the arc-shaped arrangement design is adopted for the arrangement of the cooling water pipes, replacing the traditional flat design, which can make the cooling water pipe arrangement fit the shape design of the headlight shade and improve the uniformity of the cooling of the headlight shade.
[0006] In the aforementioned precision injection mold for a motorcycle headlight shade, a sealing edge is fixedly installed at the mold closing position between the lower and upper mold bases. Concave locking modules are fixedly installed on the four sides of the top of the lower mold base, and matching convex locking modules are fixedly installed on the four sides of the bottom of the upper mold base. The convex locking modules are locked and fixed with the concave locking modules. This arrangement aims to ensure a tight seal between the upper and lower mold bases through the sealing edge. Furthermore, the cooperation between the convex locking modules and the concave locking modules allows the upper and lower mold bases to be locked after closing, thus improving the stability of the mold closing.
[0007] In the aforementioned precision injection mold for a motorcycle headlight shade, the shade mold core is assembled within the lower mold base. Mounting slots are defined on both sides of the lower mold base's top. Fixing blocks are fixed within these slots and are bolted to the shade mold core. This arrangement ensures that the fixing blocks secure the shade mold core in place.
[0008] In the aforementioned precision injection mold for a motorcycle headlight shade, the bottom end of the lower mold base is provided with a mounting plate fixedly connected to the lower fixing plate. Multiple U-shaped conduit fixing blocks are equidistantly fixed to the surface of the mounting plate. These U-shaped conduit fixing blocks engage and secure the water inlet pipe. This arrangement ensures that the U-shaped conduit fixing blocks secure the water inlet pipe, improving the stability of the water inlet pipe layout.
[0009] In the above-mentioned precision injection mold for a motorcycle headlight shade, a plurality of cooling water pipes are vertically arranged, and the bottoms of two adjacent cooling water pipes are connected via a branch pipe. The purpose of such arrangement is to ensure the conduction between the plurality of cooling water pipes.
[0010] In the above-mentioned precision injection mold for the motorcycle headlight shade, a plurality of assembly holes are equidistantly provided on both sides of the lower fixing plate and the upper fixing plate, so as to facilitate the assembly between the injection mold and the injection molding machine body.
[0011] Compared with the existing technology, the advantages of the precision injection mold of a motorcycle headlight shade of the utility model are: by arranging cooling water pipes inside the lower mold base and the upper mold base, the top and bottom of the formed headlight shade can be cooled synchronously, which effectively improves the molding efficiency of the headlight shade. At the same time, the cooling water pipes are distributed in an arc shape, replacing the traditional flat design, which can make the cooling water pipes fit the shape design of the headlight shade more closely, improve the molding cooling efficiency of the headlight shade, and thus improve the processing efficiency of the headlight shade.
