Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a device for purposefully taking out foamed coin shapes and arranging them for connection to the next process such as transfer and packaging in a styrofoam coin shape machine. This invention relates to an improvement in the transfer and reception of foamed molded products in a molding machine equipped with the same.

(Prior Art) Conventionally, a guide member is installed inside the tie bar and outside of the Styrofoam molding machine for a Styrofoam molding machine, and is used to take out the Styrofoam molding machine from the cavity of the mold using a method such as vacuum suction. A take-out machine that takes out and takes out a take-out member has been proposed.

(Problems to be Solved by the Invention) However, in all of the cases proposed so far, there have been the following problems.

■With the vacuum suction method using a take-out member such as a suction pad, the strength of the device that guides the take-out member as it moves in and out within the mold opening interval is not strong enough. There was a problem with the accuracy of getting closer, which sometimes led to errors in ejection.

■In today's world of high-mix, low-volume production, it is necessary to change the arrangement of ejecting parts for molds that are frequently replaced after the mold is replaced.
This had to be done by internal setup between the molds, which was not only dangerous but also a big problem in terms of overall work efficiency.

■Also, a transfer panel removal method has been proposed in which a transfer panel is positioned between the parted molds and the ejected foam molded body is inserted into the transfer panel and taken out, but in this case, the transfer panel is simply raised and lowered. Because it was not possible to get close to the product mold side, a gap was created between the product mold and the receiving panel, and the foam molded product had a shallow bottom that would fall out of the cavity as soon as it was ejected. In the case of a method in which the foamed coin is removed by adhering it to the parting surface of the mold, the foamed coin may fall off before it is inserted into the receiving/receiving frame, making it impossible to take out the foamed coin using the receiving/receiving panel. There wasn't.

(Object of the present invention) The present invention has been made in view of the drawbacks of the conventional examples, and its purpose is to integrally equip a device for taking out the foamed molded product, and to connect the transfer panel of the device to the mold on the product side. By making it possible to move the product, it improves take-out accuracy, improves work efficiency, and adapts to high-mix, low-volume production.
