Abstract

The invention discloses a shaping die body used for a high-speed plastic profile extrusion die. The shaping die body comprises an upper plate, a lower plate and an air duct, wherein the lower plate is fixedly connected with the upper plate; the air duct is located on the periphery of an extrusion flow channel, and the direction of the air duct is the same as the extrusion direction of the die; both the upper plate and the lower plate are provided with a plurality of air pipes in a penetrating manner, and the directions of the air pipes are perpendicular to the extrusion direction of the die; both the upper plate and the lower plate are provided with a plurality of kidney-shaped cooling water tanks and a plurality of water cooling chambers, the directions of the kidney-shaped cooling water tanks are the same as the extrusion direction of the die, and the directions of the water cooling chambers are perpendicular to the extrusion direction of the die. The shaping die body is simple in structure, and easy and convenient to machine; after the structure is adopted, water in the cooling water tanks is introduced into the water cooling chambers additionally arranged in poor cooling areas, the trafficability and the traction speed of original air channels are guaranteed, and the cooling uniformity is improved, therefore, the quality of products is guaranteed and the production efficiency is improved.

Description

technical field [0001] The invention relates to a calibrating die for high-speed plastic profile extrusion die. Background technique [0002] With the improvement of people's requirements for product quality, the requirements for the surface quality and physical properties of profiles are also continuously improved. In order to obtain the profile of the product design size, the extrusion die has very high requirements on the cooling uniformity of the calibrating die. In the general calibrating die design, the water and air paths are arranged alternately (such as Figure 4 ), so that there will be weak cooling areas in some areas in the alternation of water channels and air channels (such as Figure 4 ). In the mold with low pulling speed, the influence of cooling unevenness caused by these areas is not obvious; but in the current extrusion molding, due to the use of energy-saving, high-efficiency, and large-capacity hosts, the pulling speed of the profile is continuously inc...
