Vehicle lamp lens and three-ejection horizontal type rotary disc injection molding machine for producing vehicle lamp lens

Abstract

The invention discloses a vehicle lamp lens and a three-ejection horizontal type rotary disc injection molding machine for producing the vehicle lamp lens. The vehicle lamp lens comprises a base, a core part and an arch-shaped casing part, wherein the core part is fixedly and integrally connected with the base and is in a sphere notch shape; the arch-shaped casing part is integrally and fixedly connected with the core part; the outer wall of one end, near the base, of the casing part is provided with four light collection surfaces. The three-ejection horizontal type rotary disc injection molding machine comprises a machine frame, an injection assembly, a fixed die assembly, a moving die assembly, a die removal assembly and a die closing driving assembly, wherein the moving die assembly comprises a rotary disc and a moving die plate which are rotationally connected, and the moving die plate is fixedly connected with the rotary disc; a fixed die plate is provided with a first fixed cavity, a second fixed cavity and a third fixed cavity, and the moving die plate is provided with three same moving cavities; in the die closing process, the first fixed cavity is matched with the base, the second fixed cavity is matched with the whole structure of the core part, and the third fixed cavity is matched with the casing part; the injection assembly comprises a first ejection mechanism, a second ejection mechanism and a third ejection mechanism which are respectively communicated with the first fixed cavity, the second fixed cavity and the third fixed cavity. The three-ejection horizontal type rotary disc injection molding machine has the advantages that the effect of layered processing is realized, and the processing efficiency is high.

Description

Technical field [0001] The invention relates to the field of automobile parts processing, in particular to an automobile lamp lens and a three-shot horizontal turntable injection molding machine for producing automobile lamp lenses. Background technique [0002] In modern automobile manufacturing and processing, some parts will use injection molding process, using injection molding machine to inject thermoplastic or thermosetting material into a molding mold using a syringe-like principle to make plastic parts in various shapes. When processing relatively large parts, the more common two-plate horizontal injection molding machine is often used. For example, the Chinese patent with the authorized announcement number CN206733467U discloses a horizontal injection molding machine. A general horizontal injection molding machine mainly includes an injection molding machine frame, a feeding mechanism, a heating injection mechanism, a fixed mold fixedly connected to the injection moldin...

Problems solved by technology

However, using this method, different processes need to take out the semi-finished injection molding products and reinstall them on the mold. The workload of manual operations for mass processing is very large, which is very inconvenient.
