[Technical field to which the device belongs]

 The present invention relates to a structure for taking out a molded product in a molding machine such as a foam molding machine.

[0002]

[Prior art]

 FIG. 1 is a view showing a molding machine having a molded product taking-out structure of the present invention. However, the structure as a general molding machine excluding the molded product taking-out structure is the same as the conventional one, and therefore this drawing is shown for convenience. The general configuration of a molding machine will be outlined using.

In the figure, (1) is a fixed mold, and (2) is a fixed die plate on which the fixed mold (1) is mounted. (3) is a moving mold, and (4) is a cylinder of a drive device for reciprocating the moving mold (3). (5) is a control device for the foam molding machine, which controls the entire device. (6) is an ejector, which is slidably attached to the fixed die plate (2), and the tip of the ejector can project to the inner surface of the cavity (9). Reference numeral (7) is a filler, which is arranged so as to communicate with the cavity (9) of the fixed mold (1). Reference numeral (8) is a raw material supply cylinder, which is connected to the filler (7) and supplies the raw material beads to the filler (7). (11) is a tie bar, which is installed between the fixed die plate (2) and the cylinder plate (10) so that the moving mold (3) can reciprocate along the tie bar (11). .

The drive device (4) is operated to move the moving mold (3) toward the fixed mold (1) to close the mold, and then the filler (7) is operated to move the moving mold (3). ) And the fixed mold (1) are filled with raw material beads.

The supply of the raw material beads to the cavity (9) is performed by the raw material supply tube (8). When the raw material beads are filled in the cavity (9), high temperature steam is supplied to the steam chamber of the fixed mold (1) or the moving mold (3) to heat the raw material beads in the cavity (9) to expand the foam. Then, the foamed molded product (12) is formed. After that, after cooling the foamed molded product (12), the driving device (4) is reversely operated to separate the moving mold (3) from the fixed mold (1). When the moving mold (3) moves away from the fixed mold (1), the ejector actuating plate (6a) that works with the moving mold (3) comes into contact with the end of the ejector (6), and the ejector (6) moves. Extrude the molded product from the fixed mold (1).

As a means for taking out the extruded molded product, there has been conventionally the following type. [Prior art example 1] First, there is a means for inserting a take-out section equipped with a vacuum pad for decompressing and sucking with a pump or the like between a movable die and a fixed die, and adsorbing a molded product and transferring it to an alignment table or the like. (Not shown).

However, in the case of the vacuum pad type, when the molded product is used for taking out the foamed molded product, the mark of the suction port (so-called “kiss mark”) due to strong suction remains on the molded product, and the product price is lowered.

Further, if the suction port abutting portion of the molded product has irregularities, air cannot be sufficiently sucked in because air enters through the gap between the molded product and the vacuum pad, and the weight of the molded product is further reduced. If it is large, it will be difficult to retain by adsorption. Therefore, there is a problem that the shape and weight range of the applicable molded product are narrow.

Conventional Example 2 Next, a leaf spring type molded product takeout structure is shown in FIG. In the transfer panel (117) of the molded product take-out member (118) that moves up and down along the vertical guide (115), the molded product take-through holes (117a) are formed at regular intervals according to the molded product. , A leaf spring (117b) is provided around it, and when the ejector is actuated to push the molded product out of the cavity, the molded product is inserted into the through hole (117a) for receiving the molded product, and the leaf spring ( The outer surface of the molded product (112) is clamped and held by 117b).

In this state, the elevation drive device (133) is lowered to hold the molded product and pull down the molded product takeout member to the bottom dead center. The molded products (112) are taken out from the molded product taking-out member that has been pulled down and reached the bottom dead center, and they are successively aligned on the alignment table which is the molded product delivery position.

In this case, since the molded product (112) is collected by the molded product collecting through hole (117a) formed in conformity with the molded product (112), if the shape of the molded product (112) is changed, Since it is necessary to switch to the transfer panel (117a) that exactly matches the shape of the molded product each time, there is a problem that it is very complicated.

In addition, if the ejected position of the molded product (112) by the ejector is defective, the molded product (112) may not be inserted properly into the through hole (117a) for receiving the molded product, or the molded product (112) may not pass through the through hole for the molded product. There is a problem in that it strongly contacts the hole (117a) and scratches the outer surface for a long time. There is also a problem that in order to remove the molded product from the transfer panel (117), it is necessary to separately provide an extrusion cylinder for pushing out the molded product (112) from the transfer panel (117).

[Prior Art 3] Next, FIG. 6 shows a needle stick type molded product takeout structure proposed in Japanese Patent Laid-Open No. 7-96524. A molded product take-out member (218) that moves between the mold opening space and the molded product delivery position is provided, and a needle (219) that projects toward the molded product is implanted therein. At the time of taking out, the needle (219) pierces the molded product in the mold to hold the molded product in the molded product removing member.

However, since the needle is pierced into the molded product, needle puncture scratches naturally remain on the molded product. Further, the molded articles that can be taken out by this method are limited to those that can be pierced with a needle, such as foamed articles, and cannot be used for taking out molded articles such as hard resins and metals. Furthermore, in order to remove the molded product from the molded product take-out member, an extrusion cylinder was required as in the case of Conventional Example 2.

[Problems to be solved by the device]

 The conventional problems described above are eliminated, and there are few restrictions on the material, shape, and weight of the molded product that can be taken out, the molded product is less likely to be scratched, and changes in the size of the molded product can be easily accommodated. It is an issue to provide a molded product takeout structure.

[0016]

[Means for Solving the Problems]

 The molded product takeout structure of the molding machine of the present invention has a molded product takeout member (18) that can move between the mold opening space of the molds (1) and (3) of the molding machine and the molded product delivery position. , The molded product take-out member is capable of holding the molded product (12) between the shelf (19) on which the molded product (12) is placed and the molded product (12) by pressing the molded product (12). And a movable face plate (21).

Further, the molding machine has a molded product taking-out member (18) that can move between the mold opening space of the molds (1) and (3) of the molding machine and the molded product delivering position. 18) has an opening (13) into which a molded product can be inserted, and movable face plates (21) that can move toward the inside of the opening (13) above and below the opening (13).
