Problems solved by technology

[0002] At present, metal hot extrusion mold bases do not include heating mode. When the preheated mold is installed on a cold mold base, the temperature at the contact position between the mold and the mold base will drop, and the temperature of the lower side of the mold base is lower than that of the upper side. side, which will cause the metal fluidity on the lower side of the die to be worse than that on the upper side during the extrusion process, which will lead to uneven size and performance of the extruded product

Embodiment Construction

[0022] The present invention will be further described below in conjunction with specific drawings and embodiments.

[0023] like Figure 1-3 Shown: a kind of extruding mold seat heating device, it is characterized in that,

[0024] The heating device includes a mold base 3, a temperature controller 7, a thermocouple 6, a heating element 4, and a cover plate 5;

[0025] The mold base has a structure with an open upper end, and a stepped U-shaped through groove 3.1 is opened in the middle, and the mold 1 and the mold pad 2 are matched and placed in the U-shaped groove 3.1. The mold is placed on the front end of the mold pad and passed through the mold. Pad support; another U-shaped groove 3.2 is provided on the front surface of the mold base, and an assembly hole 3.3 for inserting a heating element 4 is arranged in the U-shaped groove, and the heating element includes a plurality of heating rods 4.1 and a plurality of Wires 4.2 for heating rod connection,

[0026] The wire i...

Abstract

The invention relates to the technical field of heaters, in particular to an extrusion die seat heating unit. The heating unit comprises a die seat, a temperature controller, a thermocouple, a heatingelement and a cover plate, wherein the die seat is of a structure with the upper end open, a stepped U-shaped slot is formed in the middle of the die seat, and a die and a die cushion are matched andput in the U-shaped groove; another U-shaped groove is formed in the front end surface of the die seat, and the heating element is disposed in the U-shaped groove; the temperature controller is disposed on one side surface of the die seat; the thermocouple is disposed beside the temperature controller; the thermocouple is relatively perpendicular to the heating element and located at the bottom of the U-shaped groove which is half of depth of the heating element. According to the heating unit, the die seat is designed to be of a structure into which the heating element and the thermocouple are inserted as shown in the figures, the temperature is controlled through the temperature controller, and then the die seat can be heated to the needed temperature.

Description

technical field [0001] The invention relates to a heating device, in particular to an extrusion die base heating device. Background technique [0002] At present, metal hot extrusion mold bases do not include heating mode. When the preheated mold is installed on a cold mold base, the temperature at the contact position between the mold and the mold base will drop, and the temperature of the lower side of the mold base is lower than that of the upper side. This will cause the metal fluidity on the lower side of the die to be worse than that on the upper side during the extrusion process, which will lead to uneven size and performance of the extruded product. The new mold base preheating device can avoid the above problems and achieve more uniform flow rate, size and performance of the product, especially suitable for multi-hole die extrusion and high-precision extrusion. Contents of the invention [0003] The purpose of the invention is to realize the preheating of the mol...
