Problems solved by technology
[0002] Under high temperature and certain pressure, pass through a die with a specific cross-sectional shape, and then at a lower temperature, shape it into a continuous profile of the desired cross-sectional shape. The production process of extrusion molding is to prepare for molding Materials, extrusion molding, cooling and setting, traction and cutting, post-treatment of extruded products (tempering or heat treatment), during the extrusion molding process, pay attention to adjust the temperature of each heating section of the extruder barrel and the die of the die, In order to obtain qualified extruded profiles, special attention should be paid to adjusting the extrusion rate of the polymer melt from the die of the machine head, because when the extrusion rate of the molten material is low, the extruded The extruded product has a smooth surface and uniform cross-sectional shape, but when the extrusion rate of the molten material reaches a certain limit, the surface of the extruded product will become rough, lose luster, and appear shark skin, orange peel, shape distortion, etc.

The invention discloses a novel mold for accelerating cooling of a metal block. The novel mold comprises brackets, bases and a mold base, wherein the brackets are arranged on the bases; the brackets are arranged on both sides of the mold base; the mold base is connected with the brackets by fixtures; and rotating disks are arranged between the fixtures and the brackets. The mold can clamp the cooled metal block, and then the rotating disks rotate to achieve the cooling effect, or the cooling liquid is poured after clamping and rotation.
Description
technical field [0001] The invention relates to the field of metal molds, in particular to a new type of mold for accelerating cooling of metal blocks. Background technique [0002] Under high temperature and certain pressure, pass through a die with a specific cross-sectional shape, and then at a lower temperature, shape it into a continuous profile of the desired cross-sectional shape. The production process of extrusion molding is to prepare for molding Materials, extrusion molding, cooling and setting, traction and cutting, post-treatment of extruded products (tempering or heat treatment), during the extrusion molding process, pay attention to adjust the temperature of each heating section of the extruder barrel and the die of the die, In order to obtain qualified extruded profiles, special attention should be paid to adjusting the extrusion rate of the polymer melt from the die of the machine head, because when the extrusion rate of the molten material is low, the extru...
