A plastic moldless molding device

Abstract

The invention discloses a plastic mouldless forming device which comprises a plasticizing part, a dripping part and a forming part, wherein a switching mechanism which the dripping part adopts is a nozzle needle, and the nozzle needle comprises a sealing ring, an elastic joint and a needle core. An actuator which has a piezoelectric property acts on the nozzle needle, so that the opening and closing of a discharging port is controlled by the needle core, an opening or closing speed of less than 0.01 s can be achieved, and requirements of three-dimensional printing for separating dimensions of high-viscosity materials are met. Problems such as leakage, abrasion and the like are avoided at the same time, and the high-frequency and microscale switching control of high-viscosity, high-pressure and high-temperature fluids is realized. A manipulator of the forming part comprises a plurality of moving joints which are driven by a control system, so that the tail end of the manipulator can be located at any position and direction. Besides, special requirements such as light sensitivity and the like for forming materials do not exist, and objects in any three-dimensional shape can be formed. The mould opening link is omitted, the production time can be saved, the production cost can be reduced, and the plastic mouldless forming device is suitable for producing one-piece or small-batch plastic products which can be used directly.

Description

technical field [0001] The invention belongs to the technical field of plastic molding technology and equipment, and relates to a device for plastic moldless molding. Background technique [0002] The production of plastic products is usually realized in large quantities by means of injection molding or extrusion molding. Although these production methods have advantages in high-precision mass production of plastic products with complex geometric shapes, these production methods require advance Prepare metal molds, which are time consuming and expensive to manufacture. [0003] With the rapid advancement of technology and the increasingly intensified competition, the product life cycle is getting shorter and shorter, and the development of new products has become the key to gaining a competitive advantage. Even if a new product is to be mass-produced, in the research and trial-manufacture stage, various improvements must be made to its structure, performance, and specificat...
