Abstract

The utility model relates to an improvement for a plastic extrusion die, and particularly to an extrusion die with double material ports for an embossed veneer. The extrusion die comprises a die body, wherein the die body is provided with a material extrusion port and a runner, and a die plate A, a die plate B, a confluence plate and a transition die plate are connected above the die body by screws respectively; and cavities are arranged on the die plate A and the die plate B respectively, a flow cavity is arranged on the lower plate surface of the die plate A, the flow cavity is communicated with two flow mixing cavities, and a lateral material extrusion port and a through hole are arranged at one side of the die plate B. The extrusion die is characterized in that a bearing seat is installed above the die plate A, two rollers are installed on the bearing seat, and the roller surface generatrixes of the two rollers are superposed with the outer side surfaces of a horizontal cavity body and a vertical cavity body in the die cavity of the die plate A. The extrusion die disclosed by the utility model solves the problems of low production efficiency and complex production process existing in the production for a plastic product with a patterned veneer, of the conventional extrusion die; and the extrusion die is mainly used for improvement for the conventional extrusion die.

Description

Extra quality mouthful of embossing facing extrusion die

The (1) technical field: the utility model relates to the improvement of plastics extrusion die, is a kind of extra quality mouthful of embossing facing extrusion die.

The (2) background technology: the prior art outer surface has the production of the plastic products of decorative pattern facing, at first is to adopt extra quality mouthful of extrusion die to produce the blank of plastic products, and then adopts rolling process to produce the decorative pattern of plastic products outer surface; The problem that the prior art extrusion die is produced the existence of decorative pattern facing plastic products is: the low and complex manufacturing of production efficiency.

The (3) summary of the invention: the purpose of the utility model is exactly will solve existing extrusion die to produce the low problem that reaches complex manufacturing of the existing production efficiency of decorative pattern facing plastic products, and a kind of extra quality mouthful of embossing facing extrusion die is provided.

The concrete scheme of the utility model is: a kind of extra quality mouthful of embossing facing extrusion die, and it has die body, and the lower end of die body is provided with crowded material mouth, is provided with runner in the die body, and the top of die body adopts screw to be connected with A template, B template, cylinder manifold and transition template respectively; Be respectively equipped with on cylinder manifold and the transition template and conflux, be respectively equipped with die cavity on A template and the B template, die cavity is L-shaped structure; On the lower face of A template, be provided with the stream chamber, the stream chamber is communicated with twice mixed flow chamber, the other end in twice mixed flow chamber be respectively with the L shaped die cavity of A template in horizontal cavity and the interior side-lower of vertical cavity side end be communicated with; One side of B template is provided with side direction crowded material mouth and through hole, and the side direction crowded material mouth in the described B template is to adopt through hole to be communicated with stream chamber in the A template; It is characterized in that: above the A template, supporting base is installed, two rollers is installed on the supporting base, the tube face bus of two rollers be with A template die cavity in horizontal cavity and the lateral surface of vertical cavity overlap installation.

Stream chamber in the described A template of the utility model be with the B template in through hole align installation up and down.

The depth value H in the mixed flow chamber in the described A template of the utility model is that a side of deflection die cavity progressively shoals.

The described roller of the utility model is provided with roll shaft, and the tube face of roller is provided with impression, and described roller is to cooperate installation with the axis hole in the supporting base of being installed above roll shaft and the A template.

The utility model is compared with existing extrusion die; The utility model is in the outside of extrusion die die cavity discharging opening the roller that has impression to be installed; Can realize that then the extrusion die one-shot forming produces the plastic products that outer surface has the decorative pattern facing; The steady quality of product, production efficiency is high; The utility model is simple in structure, effect significantly reaches the production efficiency height; The utility model preferably resolves existing extrusion die and produces the low problem that reaches complex manufacturing of the existing production efficiency of decorative pattern facing plastic products.
