Multi-channel color mixing injection molding device for upper cover of lampshade

Abstract

The invention discloses a multi-channel color mixing injection molding device for an upper cover of a lampshade, and relates to the technical field of equipment for producing and processing lighting appliances. The multi-channel color mixing injection molding device comprises a box body, a discharging mechanism, an isolation mechanism and a leading-out mechanism, the leading-out mechanism is arranged in the middle of the front end of the box body in a penetrating mode, the leading-out mechanism comprises a mounting plate which is connected to the middle of the bottom of a leading-out plate of the leading-out mechanism, rolling wheels are connected to the lower middles of the inner sides of middle supporting blocks on the two sides of the bottom of the mounting plate through rolling shafts, a discharging mechanism is connected to the middle of the front end of the leading-out plate, the discharging mechanism comprises a spraying nozzle which is connected to the front end of a discharging pipe of the discharging mechanism, a preheating pipe is connected to the middle in the discharging pipe, the isolation mechanism connected to the inner side wall of the discharging pipe comprises a set of guide rails in central symmetry, isolation pipes are arranged in the middles of the inner ends of the guide rails in a sliding mode through guide blocks, and sealing rings are connected to the end parts of the isolation pipes in a clamped mode. According to the multi-channel color mixing injection molding device, the isolation mechanism, the discharging mechanism and the guiding-out mechanism are arranged, so that the device has the advantages that cleaning in the channel and dismounting of a spiral propelling structure are easy, the labor intensity is reduced, and use is convenient.

Description

technical field [0001] The invention belongs to the technical field of equipment for production and processing of lighting appliances, in particular to a multi-channel color-mixing injection molding device for a lampshade upper cover. Background technique [0002] Lighting supplies generally refer to appliances that can be illuminated. Lamps belong to lighting appliances, and lampshades are one of the components of lamps. The lampshade not only covers the lamp to gather the light, but also prevents electric shock and protects the eyes. In the process of processing the lampshade, the injection molding device is an indispensable device. [0003] After retrieval, China Authorized Patent No. CN105392232A, authorized publication date 2016.03.09, discloses an LED multi-channel color-mixing smart light bulb, which includes at least four color-mixing channels and at least four sets of color LED chips or LED light source components, enabling the light bulb to reproduce Now it is inf...

AI Technical Summary

Problems solved by technology

[0010] The object of the present invention is to provide a multi-channel color-mixing injection molding device for the upper cover of the lampshade. By setting an isolation mechanism, a material discharge mechanism and a lead-out mechanism, the existing injection molding device is solved. The channel used for injection molding is a single tubular structure with a certain depth. After a long period of use, it is very inconvenient to clean the inner wall. At the same time, the raw materials injected into the channel are generally heated and melted, but part of the heat is lost during transportation, which will easily affect the discharge effect of the channel. The screw rod used to propel the raw material is generally disassembled by disassembling the channel for its disassembly and maintenance. The steps are cumbersome, and the collision during the disassembly process may easily cause damage to the inner wall of the channel, which increases the cost.
