Abstract

PURPOSE: A takeup arm of an automatic takeup device for an injection molder is provided to correspond to a narrow mounting space by reducing the height of a mechanism remarkably through 2-step descending of an arm and to simplify the structure by rotating the arm simply. CONSTITUTION: A sleeve(19) is assembled to a primary descending plate(18) and a secondary descending plate(22) is assembled to a guide bar(20) inserted into the sleeve and a secondary descending cylinder(16) rod. A clamper(23) is mounted under the secondary descending plate. A primary descending cylinder rod is extruded down when compressed air is injected into the upper portion of a primary descending cylinder. The primary descending plate assembled to the rod descends. Then, the secondary descending cylinder, sleeve and guide bar descend by the secondary descending cylinder inserted into the sleeve.

Description

Telescoping arm enable swing of automatic take-off machine for injection molding machine

The present invention relates to an arm of an automatic ejector for automatically ejecting a molded product or sprue by mounting a thermoplastic synthetic resin into an injection molding machine, and more specifically, to a rotating function while descending to two stages. It is related with the extraction arm provided.

The automatic ejector for the injection molding machine is generally installed and operated on the fixed plate of the injection molding machine. When the space between the injection machine and the ceiling, that is, the installation space of the ejector is small, the height of the ejector itself needs to be reduced. In the case of the case, in order to make the ejector itself compact, it is common to use a two-stage descending method. However, in the conventional method, a stroke expanding mechanism or a lead screw and a servo motor (Servo motor) are used. However, they have a problem that the machine is complicated and expensive to manufacture. Furthermore, if it needs to swing, the arm itself does not have a rotating function. Since the frame or the sidebar itself has to be rotated, there are parts for other movements installed there, Lin deona is a problem that must rotate the entire core component generated for the take-out operation such as a motor, the guidance bearing, ssenseo.

The present invention corresponds to a narrow installation space by greatly reducing the height of the machine by using the two-stage lowering method, and by having a rotation function, the machine itself is simple and the manufacturing cost is extremely low because only the arm itself rotates without any other parts rotating. It becomes cheap.

The present invention relates to the ejection arm of the automatic ejector, and thus, the structure of the arm is exemplified except for the overall structure or the parts structure and the manner of operation for other operations.

Hereinafter will be described in detail with reference to the accompanying drawings.

In Fig. 2, the base plate 1 (which is attached to the frame or side bar of the take-out machine and assembled with parts for other operation) forms a demand 1 'under the reference plate 1 and the rotating plate 2 A hinge 3 is formed on the lower side of the lower side to fit the request 1 'of the reference plate 1, and is assembled with the pin 4 and the bolt 5 as shown in FIGS. 2 and 4.

In Fig. 3, a long hole 1 "is formed on the upper side of the reference plate 1, and the pin 7 is inserted in accordance with the swinging bracket 6, and assembled with a bolt 8. The swinging bracket 6 ), A rotating cylinder 9 is assembled as in FIG.

In FIG. 2, the protrusion 10 is formed on the upper side of the rotating plate 2, and the recessed portion 10 ′ is formed in the middle of the protrusion 10, and then assembled to the rod of the rotating cylinder 9 as shown in FIG. 4. Inserted bracket 11 is assembled into pins 12. The primary lowering cylinder 13 is assembled on the left side of the projection 10.

In FIG. 5 a second projection 14 is formed on the upper back of the rotating plate 2, in which a sleeve 15 is assembled. The secondary lowering cylinder 16 is inserted into the sleeve 15, and the cylinder itself serves as a guide bar during the primary lowering and simplifies the structure without a separate guide bar.

In FIG. 6, the rod 17 of the primary lowering cylinder 13 is assembled with the primary lowering plate 18, and the secondary lowering cylinder 16 is mounted thereto, so that the secondary lowering cylinder 16 when the primary lowering is performed. Is guided to the rib 15 is moved up and down to serve as a guide bar.

6, 7 in the primary lowering plate (18) to assemble the sleeve 19, the secondary lowering plate in the rod 21 of the guide bar 20 and the secondary lowering cylinder (16) inserted into the sleeve (19) 22 is assembled. Underneath the second lower plate 22 is assembled tongs (23).

In the present invention configured as described above, when compressed air is injected into the upper side of the primary lowering cylinder 13 and the rod 17 is extruded downward, as shown in FIG. 6, the primary lowering plate 18 assembled to the rod 17 is shown. ) Is lowered, so that the secondary lowering cylinder 16, the sleeve 19, the guide bar 20, and the like assembled to the primary lowering plate are inserted into the sleeve 15 by the secondary lowering cylinder 16. Guided down.

In FIG. 7, when pneumatic pressure is applied to the upper side of the secondary lowering cylinder 16, the rod 21 is extruded, and the secondary lowering plate 22 assembled therein is guided to the guide bar 20 and descends, and a bundle of tongs ( 23) reaches the take-out position.

If the pneumatic pressure of the primary and secondary cylinders is reversed, it rises to the standby state.

In FIG. 8, when pneumatic is applied to the upper side of the rotating cylinder 9 and the lot 24 is extruded, the rod pushes the rotating plate 2 assembled with the metal fitting 11, and the rotating plate rotates the pin 4 around the rotating shaft. . In the rotating state, as in the vertical state, the lowering and raising operations are performed.

The two-stage arm reduces the size to cope with a narrow installation space, and also includes a rotating function to simplify the machine structure, thereby reducing the manufacturing cost.
