Movable distribution plastic mixture compression molding machine

Abstract

The invention relates to a movable distribution plastic mixture compression molding machine. The machine is characterized in that: the machine comprises a mold-closing molding mechanism; the mold-closing molding mechanism comprises an upper fixed die plate and a lower fixed die plate; the upper fixed die plate is connected with the lower fixed die plate through a pull rod; a movable die plate is arranged on the lower fixed die plate; the movable die plate comprises a die-closing oil cylinder and die-opening oil cylinder; a model plate is arranged on the movable die plate; and the movable die plate is characterized in that the model plate has a mobile device, the mobile device drives the model plate to move out of the die-closing molding mechanism and move into the die-closing molding mechanism, a material distributor is arranged on the model plate which is out of the die-closing molding mechanism, and a material discharge port of the material distributer blanks materials to the model plate. According to the scheme which adopts a mode of simultaneously moving the model plate and blanking, the materials are uniformly distributed on the model plate, and then are subject to compression molding. Compared with hot press molding and injection molding, the plastic injection molding pressure does not need to be considered, phenomena that materials are cold and material injection is not in place do not occur, the materials are uniformly distributed, the overall strength of compressed products is good, the specification is neat, so the machine of the present invention is especially suitable for large-area thin-wall product molding.

Description

technical field [0001] The invention relates to a mobile distributed plastic mixture molding machine, which belongs to the field of plastic machinery. Background technique [0002] Production is the sheet material that is material with plastic mixture (plastic and wood powder, stalk etc. mix), as wood-plastic board etc., prior art adopts extruder to extrude or hot press machine thermocompression molding. The extruder extruded products have many defects, the specifications are not neat, and the production speed is slow; when the hot press is hot-pressed, the material is placed in the center of the hot-pressing plate for hot-pressing, and the material is not uniform during hot-pressing, resulting in the formed product The center has high density and strong strength, while the surrounding area has low density and poor strength. Therefore, the inventor once designed a "wood-plastic board injection molding machine", and applied for a Chinese patent number of 200820169001.9, whic...

AI Technical Summary

Problems solved by technology

However, in actual production, especially when producing large-area plates, due to the limited injection pressure of the injection molding machine and the easy cooling of the material, the injection is not in place, which seriously affects the appearance and internal quality of the product.
