AI Technical Summary
Existing LED lamp bead molds lack guiding structures during molding, resulting in poor mold molding quality. Furthermore, traditional guiding structures are costly, and the molten plastic tends to solidify, affecting the molding process.
A mold with a low-cost guiding structure was designed, including a mold guiding mechanism and a heating mechanism. The mold guiding mechanism achieves stable descent of the upper mold base through components such as bolts, ear plates, guide rods and guide holes. The heating mechanism maintains the molten plastic in a liquid state through a hot air inlet pipe, a copper heat-conducting plate and a temperature control system.
This achieves stability during the descent of the upper mold base and liquid retention of the molten plastic, improving the molding quality of the mold and reducing manufacturing material costs, thus ensuring the molding effect of the LED beads.
