Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for extracting a polyethylene terephthalate resin expansion molding piece immediately after molding from a core of an injection molding apparatus and conveying it to the next process.
It is possible to reliably transport a large number of pieces to a desired location for the next process without changing their arrangement position without damaging the pieces.

That is, the present invention is an apparatus in which a piece is held between the main body and the piece can be transported as it is from the injection molding apparatus to a desired location in the next process by a moving mechanism.

Embodiments of the present invention will be described below with reference to the drawings.

What is shown in FIGS. 1 and 2 is the main body 1 in the present invention.
However, this main body 1 has a flat front plate 20 and a rear plate 30.
The front plate 20 and the rear plate 30 are configured to slide relative to each other in accordance with the vertical movement of a hydraulic cylinder 40 attached to the back surface of the rear plate 30, and the front plate 20 and the rear plate 30 are arranged in surface contact with each other. A gate G protruding from the center of the bottom of a piece P for molding an increased salary made of polyethylene terephthalate resin can be clamped or released.

First, the flat plate-shaped front plate 20 is arranged so that its front face faces a male mold 51 of an open injection molding apparatus (see FIG. 5), and a core protruding into this male mold 51 52
The same number of vertical holes 21 are bored in the same arrangement corresponding to the
The vertically elongated hole 21 has a desired length that allows the gate G of the piece P to enter the lower end thereof.

Further, on the front surface of the front plate 20, a pedestal 22 is protruded directly below the vertically elongated holes 21, which are bored in large numbers.
When the gate G is located at 1, the piece P itself can be placed. Therefore, the protruding position of the pedestal 22 is below the lower end of the vertically elongated hole 21 by the radius of the piece P. Next, the flat rear plate 30, which is arranged so as to overlap the back surface of the aforementioned front plate 20, includes:
Relief holes 31 are formed opposite to the lower part of each vertical hole 21 in the front plate 20, so that when the gate G enters the vertical hole 21, the tip of the gate G does not collide, so that the gate G is completely inserted. It is designed so that it can enter into the vertically elongated hole 21 of the front plate 20. At the upper part of the relief hole 31, there is a presser part 32 which is slidably positioned within the vertically elongated hole 21 of the front plate 20.
is installed protrudingly.

This holding portion 32 holds the gate G, which was located within the lower end of the vertical hole 21, between the lower end surface of the vertical hole 21 when the front plate 20 and the rear plate 30 are slid relative to each other as described later. It is something. That is, as is clear from FIG. 3, the presser part 32 has a presser plate 32b that is constantly receiving a downward force from a spring 32a, and the front plate 20 and the rear plate 3
0 slides relative to each other, the action of the spring 32a moves the gate G between the lower end surface of the vertical hole 21 and the holding plate 32b.
It is designed so that it can be held comfortably and reliably between the lower surface and the lower surface. Furthermore, inside the holding plate 32b, there is also a pin 32 which is constantly pushed upward by a spring 32c.
d is built-in, and the upper part of the pin 32d is a presser part 32.
It penetrates through and protrudes above the presser part 32. The pin 32d rises relative to the rear plate 30 when the gate G is clamped, and a limit switch (not shown) provided above the pin 32d detects the clamping of the gate G. This makes it possible to send a signal for the next operation. Further, a slide plate 32e is integrally provided at the front end of the presser part 32 so as to protrude from the front plate 20, and the inner surfaces of both ends of the slide plate 32e are in surface contact with the front surfaces of the front plate 20 on the left and right sides of the vertically elongated hole 21 so that it can slide. The front plate 20 and the rear plate 30 are old.
The assembly has been achieved.

Next, the hydraulic cylinder 40 that operates in the vertical direction is connected to the rear plate 30.
It is attached to the rear plate 30 via a bracket 33 fixed to the upper rear surface so as to be vertically slidable.

That is, a vertical pin 41 is exposed on the side of the cylinder 40, and the bracket 33 is attached to the vertical pin 41.
The rear plate 30 and the cylinder 40 are able to move up and down relative to each other. Further, a frame body 42 is provided hanging down from the lower end of the cylinder 40, and the frame body 42
A pinion 43 is attached to the inner lower part. cylinder 4
A rack 35 that meshes with the pinion 43 is connected to the lower end of the piston rod 34 that moves up and down due to
Furthermore, the lower part of this rack 35 is fixed to the lower back surface of the rear plate 30 via a bracket 35.

Therefore, as described above, the rear plate 30, the bracket 33, the piston rod 34, the rack 35, and the bracket 36 are integrally assembled via pins, etc., so that the rear plate 30 is moved by the operation of the cylinder 40. will move up and down with respect to the cylinder 30. Next, 23 is also a rack, and a rack 35 is connected to the piston rod 34 mentioned above.
The rack 23 is located against the rack 23 and is slidably incorporated into the frame body 42 and meshed with the pinion 43.
is integrally fixed to the front plate 20 via a connecting pin 24 loosely fitted into a vertically elongated hole 37 bored in the lower part of the rear plate 30.

The main body 1 has the configuration as described above, but as is clear from FIG. 4, the piston rod 34 is in a lowered state with respect to the cylinder 40 (FIG. (This is the same condition as in Figure 2).

Therefore, when hydraulic pressure is applied to raise the piston rod 34, the pinion 43 that meshes with the rack 35 connected to the piston rod 34 rotates in the direction of the arrow, and the rack 23 integrated with the front plate 20 moves in the direction of the arrow. direction, that is, descending. Therefore, through this series of operations, the front plate 20 and the rear plate 30
and slide up and down relative to each other. Therefore, the longitudinal hole 37 of the rear plate 30 into which the connecting pin 24 connecting the front plate 20 and the rack 23 is loosely fitted has a length that does not obstruct the connecting pin 24 during this mutual vertical movement. must be maintained. The front plate 20 and the rear plate 30 move up and down relative to each other as described above, but since the cylinder 40 is further fixed to the upper moving mechanism 60 as described later, the rear plate 20 moves up and down as the piston rod 34 rises. The plate 30 rises relative to the cylinder 40 and the front plate 20, and the positions of the front plate 20 and the cylinder 40 themselves do not change at all.

In the main body 1, when the gap between the lower end surface of the longitudinal hole 21 of the front plate 20 and the lower surface of the holding part 32 of the rear plate 30 is sufficiently opened (that is, when the piston rod 34 is rising),
The gate G of the piece P is positioned in this gap, and then the piston rod 34 is lowered to move the front plate 20 and the rear plate 30 up and down relative to each other. This means that the gate G can be held between the two.

Now, the main body 1 having the configuration and function described above can fully exhibit its functions when attached to the moving mechanism 60, the outline of which is shown in FIGS. 5 and 6.

First, a rail 61 is installed above the opening of the injection molding device 50 to the desired location of the next process, here the cutting device 70 of the gate G. A movable body 62 that slides left and right is attached to the movable body 62.
Front and rear cylinders 63 are installed horizontally in a manner perpendicular to the front and rear cylinders.

An upper and lower cylinder 64 is vertically attached to the front end of the piston rod 63a of the front and rear cylinders 63, and the upper end of the cylinder 40 of the main body 1 is connected to the lower end of the piston rod 64a of the upper and lower cylinders 64. Therefore, in FIG. 5, the main body 1 is moved left and right along the rail 61 by the movable body 62, moved back and forth by the front and rear cylinders 63, and moved up and down by the up and down cylinders 64.

Therefore, for example, in order to operate the apparatus according to the present invention, the main body 1 is first raised by the upper and lower cylinders 64, brought closer to the movable body 62 by the front and rear cylinders 63, and then moved upward by the movable body 62 between the molds of the injection molding apparatus 50. to be located.

On the other hand, the piece P immediately after molding is attached to the protruding core 52 of the male mold 51 of the injection molding device 50 that has been opened, and the main body 1 is attached to the surface of the male mold 51.
In order to make the front plate 20 face each other at a predetermined position, the front and rear cylinders 6
3 and the upper and lower cylinders 64 are operated.

Then, the front and rear cylinders 63 are further actuated to bring the main body 1 closer to the male mold 51, and the gate G of the piece P is placed in the predetermined position of the longitudinal hole 21 of the front plate 20 as described above. Next, when the main body 1 clamps the gate G of the piece P by operating the cylinder 40 as described above, the front and rear cylinders 63 operate to horizontally extract the piece P from the core 52.

At this time, since the piece P is attached almost tightly to the core 52, if an attempt is made to move the front plate 20 up and down to achieve clamping, there is a risk that the piece P itself will be deformed. Therefore, in the present invention, the front plate 20 in the main body 1 is adjusted so that the position of the longitudinal hole 21 of the front plate 20 that is reliably aligned with the piece P fitted in the core 52 does not shift.
When the rear plate 30 and the rear plate 30 move vertically relative to each other, only the rear plate 30 is configured to move vertically. Now, the main body 10 from which the piece P has been extracted is raised by the upper and lower cylinders 64, moved by the movable body 62 above the gate cutting device 70 in this embodiment, and further moved by the front and rear cylinders 6
3 and the upper and lower cylinders 64, the piece holder 71 of the cutting device 70 is positioned opposite to the piece holder 71. Then, in the next process, in order to remove a certain gate G, the piece P is moved to the piece holder 7.
The cutter 72 performs cutting. The device according to the present invention has the configuration and functions as described above.

Therefore, it is possible to transport a large number of polyethylene terephthalate resin bottle molding pieces immediately after molding to the next process without disrupting the arrangement during molding, and to remove the pieces from the core by holding the gates of the pieces. Moreover, since the piece is transported as it is, the piece body, which is easily damaged immediately after being formed, is not damaged.
