A plate extrusion forming die for plate processing

Technical Field

The utility model relates to the technical field of plate processing, in particular to a plate extrusion molding die for plate processing.

Background Art

Moulds are various moulds and tools used in industrial production for injection moulding, blow moulding, extrusion, die-casting or forging, smelting, stamping and other methods to obtain the required products. In short, moulds are tools used to make moulded objects. Such tools are composed of various parts, and different moulds are composed of different parts. They mainly achieve the processing of the shape of the object by changing the physical state of the moulded material. There are many types of moulds. According to the processing object and processing technology, they can be divided into: moulds for processing metals, moulds for processing non-metals and powder metallurgy, including plastic moulds, rubber moulds and powder metallurgy moulds, etc. According to the structural characteristics, moulds can be divided into flat punching moulds and cavity moulds with space. They are known as the "mother of industry".

The molding method of allowing plastic in a viscous flow state to pass through a die with a specific cross-sectional shape under high temperature and high pressure, and then cool and shape it at a lower temperature to produce a continuous profile with the desired cross-sectional shape is called extrusion molding. The existing plastics take a long time to cool and mold in the mold cavity, so there is an urgent need for a sheet extrusion molding die to solve the problem.

For example, a sheet extrusion forming die disclosed in Chinese patent CN213227457U, through the coordinated use of a connecting rod, an air box, a piston plate, an air outlet pipe, a connecting port and a heat conducting rod, blows air through the connecting port to accelerate the dissipation of the temperature of the outer surface of the heat conducting rod, thereby accelerating the forming speed of the sheet and improving work efficiency; the utility model uses the exhaust port and the template in coordination to discharge the gas inside the mold cavity during the process of pressing the upper mold down, thereby avoiding the problem of a large number of bubbles on the formed sheet.

However, the upper die and the lower die in the mold are fixed in the mold, so that only one specification of plate can be produced.

For this reason, we urgently need to provide a sheet material extrusion forming die for sheet material processing with replaceable upper and lower dies.

After the hot melt plastic is cooled, the hydraulic cylinder 4 is started to drive the movable plate 5 to move upward to drive After the upper template 7 is away from the lower template 8, the formed sheet is taken out of the mold cavity. When the mold equipment needs to process sheets of other specifications, the baffle 905 is pressed into the rectangular groove until the baffle 905 moves to the inside of the rectangular groove, and then the upper template 7 and the lower template 8 are pulled forward to drive the rectangular rod 903 to be pulled out of the limit frame 901, and then the rectangular rods 903 at both ends of the upper template 7 and the lower template 8 for processing sheets of other specifications are slid into the limit frame 901, and then the baffle 905 is released and the spring 904 rebounds to push the baffle 905 to the front end of the upper template 7 and the lower template 8, completing the replacement of the upper template 7 and the lower template 8 and then processing sheets of other specifications.
