Straight line type high-speed single-cylinder injection mechanism

Abstract

The invention discloses a straight line type high-speed single-cylinder injection mechanism which comprises an injection base, wherein a front injection plate and a rear injection plate are arranged on the injection base; the front injection plate and the rear injection plate are connected through four guide rods up and down; a charging barrel is mounted on the front injection plate; a screw is mounted in the charging barrel; an injection head is mounted at the head of the charging barrel; a hopper is mounted on the charging barrel; a middle injection plate is arranged between the front injection plate and the rear injection plate; a sliding block is arranged on the bottom surface of the middle injection plate; a linear guide rail is mounted on the injection base; the sliding block is matched with the linear guide rail; an oil motor is mounted on the rear wall of the middle injection plate; a screw connector is arranged on the front wall of the middle injection plate and is connected with the screw; a single-cylinder injection oil cylinder is mounted on the rear wall of the rear injection plate; and a piston rod of the single-cylinder injection oil cylinder penetrates through the rear injection plate to be connected with the oil motor. According to the scheme, the straight line type high-speed single-cylinder injection mechanism is small in occupied area and energy consumption, low in cost and high in efficiency.

Description

Technical field [0001] The invention relates to an injection molding machine, in particular to a linear high-speed single-cylinder injection mechanism for an injection molding machine, belonging to the field of plastic machinery. Background technique [0002] The injection mechanism is a device used by the injection molding machine to heat and plasticize the thermoplastic material and squeeze the plasticized material into the molding die. The injection mechanism of the current injection molding machine mostly adopts a double-cylinder injection structure. Two injection cylinders are symmetrically arranged between the injection front plate and the injection rear plate. The oil motor is installed on the outer wall of the injection rear plate, making the base of the injection mechanism very long. , Takes up a lot of space. In particular, the double oil cylinder consumes a lot of fuel during injection, and requires high precision to achieve the balance of the injection movement on bo...

Problems solved by technology

The injection mechanism of the current injection molding machine mostly adopts a double-cylinder injection structure. Two injection cylinders are symmetrically arranged between the injection front plate and the injection rear plate, and the oil motor is installed on the outer wall of the injection rear plate, making the base of the injection mechanism very long. , takes up a lot of space

In particular, the double oil cylinder consumes a lot of fuel during injection, and requires high precision to achieve the balance of injection movement on both sides, resulting in high processing and maintenance costs and low production efficiency.
