Description

The injection molding syringe-press is known, which includes the material cylinder, the rotary disk with the molds and the mechanism for their disclosure. The described injection syringe-press automation is simpler and allows drying of the plasticized mass injection and closing the molds with one mechanism for one cycle of the machine.

To this end, the housing of the rolling material cylinder and its piston rod are kinematically connected with the shaft, by means of a connecting rod, driven by a camshaft.

The mechanism for opening the molds is made in the form (driven from the camshaft through the eccentric, pusher and angle lever and located on one side of the swivel disk) spring-loaded strips with pins passed through the holes of the disk and through the holes attached to it from the other side of the lower mold covers, with the top covers of the molds attached to the pins.

FIG. 1 shows a kinematic:; hema injection syringe-press machine; in fig. 2 is a diagram of the mechanism for disclosing p) ess-fo: 1M without showing its drive.

A disk / e with several molds mounted on it is mounted on shaft 2. All bottom covers 5 of the molds are also fixed on the disk on one side, and the top cover 4 of each mold is fixed on the ends of two pins 5. On the pins 5 installed in the holes of the disk 1 n in the holes of the lower covers 3, on the other side of the disk are put on the springs 6. The springs 6 abut against the bar 7 connecting the ends of the pins 5 and, moving in the direction of the arrow A, close the press form.

On the camshaft 8 of the machine, eccentrics 9 and JO are mounted. The eccentric 9 through the pusher 11 and the angular lever 12 acts on the bar 7. The eccentric Yu through a tooth fixed on the pusher 13 and interacting with the last ratchet wheel mounted on the shaft 2 produces a turn of the disc.

The body of the m.crystal unit M by means of the lever 15, the spring damper 16 and the piston rod / 7 is connected to the connecting rod 18. The rod 19 nopujn 20 of the cylinder 14 through the hydraulic or spring damper 21 pressure theory and the KI; 1I,: s 22 also It is connected with shatuyom 18. The hydraulic damper 2} of pressure is a cylinder filled with liquid, which is affected by a piston, whose joint is connected to the slide 22. When the pressure is increased, the liquid has been removed from the cylinder of the damper 2 for the body through the switch; valve in the collection, from where we will turn to shares re-enters the cylinder ha;: itel when it moves back.

Before starting work, the material cylinder 14 is heated with the help of electric heating etemtep to a certain temperature of 1 m, and a pressure-feed is loaded into the funnel 23. After switching on the drive of the press porognok, coming from the funnel 23 into the cylinder 14, porsche 20, Grot; 1, it turns out, with turning towards the nozzle, where the section is tavits. In the course of the next movements of the Norshi 20, the molten mass is plasticized mass is injected into the mold. When the shaft 8 is rotated, the rod 18 rotates the spider arm 22 on the rider 24, causing the cylinder 14 to press against the mold, and the piston 20 injects a plasticized mass into the mold, which solidifies in it. The eccentric 9 acts through the plunger // and the angular lever 12 on the bar 7, which opens the mold through the pins 5, with the top cover 4 advancing by a casting hole on the fixed stop 25, as a result of which the product with the sprue is pushed out of the preos shape into the collecting box. During the subsequent rotation of the shaft 5, the piston 20 occupies the initial position, and the eccentric 10 through the pusher 13 turns the disc / at a predetermined angle and the cycle of operation of the injection molding and priming presses of the automaton ....
