Abstract

The invention relates to a multilevel telescopic cylindrical type nozzle color mixing mechanism which is suitable to produce products with color mixing, multilayer color mixing or interlayer color mixing requirements in a plastics injection molding way. The multilevel telescopic cylindrical type nozzle color mixing mechanism comprises a valve core nozzle device and a multilevel telescopic cylindrical assembly, wherein the valve core nozzle device is fixed on a front supporting plate, the multilevel telescopic cylindrical assembly is fixed on a rear supporting plate, the valve core nozzle device is connected with the multilevel telescopic cylindrical assembly, and the front supporting plate and the rear supporting plate are oppositely fixed on four positioning rods by round nuts. The multilevel telescopic cylindrical type nozzle color mixing mechanism is also provided with round threads which tightly support the round nuts through stop screws. The invention controls a valve core to move through a plurality of layers of cylinders, thereby controlling the multilayer injection of a plurality of plastics so as to lead the products to achieve the effect of color mixing, multilayer color mixing or interlayer color mixing.

Description

technical field

[0001] The invention relates to a multi-stage sleeve type nozzle color mixing mechanism, which is suitable for plastic injection molding to produce products requiring color mixing, multi-layer color mixing or interlayer color mixing. Background technique

[0002] Generally, in the molding of plastic products, products of various colors are involved, and there are more mixed-color and clear-color products, while interlayer mixed-color products require less technology developed in China. Chinese patent ZL200620101766 "Interlayer Mixed Color Common Injection Mold" discloses a sandwich mixed color shared injection mold for producing interlayer mixed color plastic products. The flow channel in this patent is controlled by a one-way valve, and the structure of the diverter valve core is determined. Runner A and runner B cannot be opened at the same time, that is, the actions can only be completed in sequence. When one check valve is opened, the other check valve ca...

Embodiment Construction

[0015] see figure 1 , the present invention comprises a spool type nozzle device I and a multistage cylinder assembly II, the spool type nozzle device I and the multistage cylinder assembly II are respectively fixed on the front support plate 9 and the rear support plate 18, the front support plate 9, Rear support plate 18 is relatively fixed on four positioning rods 17 with round nut 8, because the two ends of positioning rod 17 are provided with steps, so after front and rear support plates are fixed by round nut 8, front support plate 9 and rear support plate 18 The relative position between them has been determined. In order to prevent the loosening of the nut 8, a round nut 7 is provided and tightened with a loosening screw. Spool type nozzle device 1 comprises: nozzle 1, material distribution body 2, thimble 3, washer 4, material plug body 5, transition seat 6, heating ring 27, thermocouple 28. Wherein the transition seat 6 is fixed on the middle position of the front ...
