Problems solved by technology
However, in the current extruder technology, it is seldom possible to quickly change the mold when it is necessary to change the mold, and the current mold change technology is to heat the mold in the heating furnace to a certain temperature and then replace it. Take it out and install it at the extrusion port. This technology does not bring efficient work efficiency. If there are many types of products and low output, the work efficiency will be greatly reduced.

The invention discloses a quick mould replace device for an extruder, and relates to the technical field of section bar processing equipment. The quick mould replace device comprises a machine enclosure, a mould and mould holes. The quick mould replace device is characterized by further comprising a mould gear and a pre-heating device, wherein the mould gear is arranged in the machine enclosure and is rotatably connected to the machine enclosure; the mould holes are uniformly formed in the mould gear; the outermost layer of the mould gear is equipped with cam gears which are arranged at equalinterval; one cam gear in the outward radial direction of the mould gear corresponds to the mould holes; a fixed screw is formed in a position, in the radial direction of the mould gear, of the cam gear; and the preheating device surrounds the mould holes, and is arranged on the mould gear. The preheating device and the mould gear are combined, so that the mould can be preheated in advance; and while the mould needs to use, the mould is quickly put into use. The quick mould replace device is extremely high in working efficiency, is suitable for a multi-batch multi-kind condition of small products, and has an extremely good application prospect.
Description
technical field [0001] The invention relates to the technical field of profile processing equipment, in particular to a quick mold change device for an extruder. Background technique [0002] Metal extrusion machine is the most important equipment for metal extrusion processing. Metal extrusion processing is an important method of metal plastic pressure forming. Its important feature is that the processing of metal ingots into tubes, rods, and profiles can be completed in an instant, and there is hardly any other method that can match it. Decoration materials for beautiful and elegant buildings; aircraft flying across continents and oceans; spaceships and space stations that allow human beings to explore outer space; are closely related to extrusion processing. However, in the current extruder technology, it is seldom possible to quickly change the mold when it is necessary to change the mold, and the current mold change technology is to heat the mold in the heating furna...
