Description

TECHNICAL FIELD

[0001] The utility model relates to injection molding machine technical field, concretely relates to a full -automatic EVA vertical disc injection molding machine. BACKGROUND

[0002] The disc type plastic injection molding machine is a kind of equipment specially used for manufacturing plastic shoe sole, and multiple shoe sole molds of the same style and different sizes are usually arranged on the disc, so the mold needs to be arranged on the rotating disc to be injection molded by the plastic injection molding machine for the mold of the same style and different sizes, and the mold opening and the molded shoe sole taking out and other process operations are facilitated.

[0003] Chinese patent CN200710128914.6 discloses a vertical disc plastic injection molding machine, which comprises a rotating disc device, an injection device and a mold closing device; the rotating disc device comprises a rotatable disc and a driving device for driving the rotation of the disc; the injection device comprises an injection frame, a vertical pre-plasticizing mechanism, an injection cylinder and an injection head arranged on the injection frame; the mold closing device comprises a mold closing frame and a mold closing cylinder arranged on the mold closing frame and below the disc, and the mold closing cylinder piston can move up and down reciprocally.

[0004] The working process of the vertical disc plastic injection molding machine is as follows:

[0005] (1) position multiple molds on the disc, and the number of molds is determined according to the size of the disc, the size of the mold and actual needs, and generally, there are 16 to 30 molds; then start the disc driving device to rotate the disc; when the disc rotates to a suitable position, the disc driving device stops rotating, and the disc also stops rotating, at this time, one mold is just located below the injection head;

[0006] (2) the mold closing cylinder piston moves from top to bottom, pushes the mold closing cylinder seat to move downward, thereby driving the injection head to move downward through the injection frame until the injection head is pressed on the mold, and the injection head is aligned with the injection port of the mold;

[0007] (3) the injection device starts injection work, the injection cylinder piston shortens, the screw applies pressure to the plasticized fluid material in the barrel, so that the material is injected into the mold cavity through the injection port of the mold from the discharge channel in the injection nozzle; when the injection amount of the plastic fluid reaches the preset amount, the injection cylinder piston stops moving downward, that is, the injection of the plastic fluid into the mold cavity is stopped;

[0008] (4) after the injection device stops injecting material, the mold closing cylinder piston further pulls and presses the injection head on the upper surface of the mold for a period of time to perform delay pressure maintaining operation, also known as locking work, so as to facilitate the cooling and fixing of the plastic fluid in the mold cavity to form a molded product;

[0009] (5) When the mold oil cylinder piston completes the delay pressure keeping work, the mold oil cylinder piston starts to move upward from the bottom, and simultaneously drives the injection frame to move upward together, until it returns to the starting position; then the disc driving device is started again and the disc is rotated to the next appropriate position, so that the next mold is just located directly below the injection head; the vertical disc plastic injection molding machine starts the next round of injection molding operation.

[0010] A main disadvantage of this kind of plastic injection molding machine is that the multiple molds on the disc are positioned and fixed on the disc by means of bolts or welding, which is troublesome to replace or disassemble and maintain, and the molds are heavy, which is laborious to install or disassemble on the disc, and the position adjustment of the molds after installation is troublesome, resulting in difficulty in aligning the injection port of the mold with the injection head of the injection device.
