Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a molded product take-out device that takes out a molded product molded in a molding section provided in a mold device that performs injection molding of a material to be molded such as a synthetic resin.

Conventionally, in a mold device that performs injection molding of materials to be molded such as synthetic resin, a method for removing the molded product is to suck the molded product using a suction device installed separately from the mold device. The extraction method is used.

In this method of suctioning out the molded product using a suction device independent of the mold device, after the material to be molded is molded, the suction is carried out at the point where the upper and lower molds that make up the molding section are completely opened. Since the device is configured to enter between the upper mold and the lower mold, the molding cycle from molding to removal of the molded product is long, and efficient molding cannot be performed. In addition, it is necessary to configure a sequence for driving the suction device in connection with mold opening of the mold device, which complicates the drive circuit of the molding machine into which the mold device is incorporated, and ultimately increases the cost of the entire device. I get used to it.

Furthermore, as another method, after molding, a part of the mold including the molded part is taken out of the mold apparatus with the molded product attached, and then the mold is opened and the molded product is sucked out. Even with this method, the molding cycle from molding to suction is long and efficient molding cannot be performed.

Therefore, the present invention provides a slide block equipped with a suction port connected to a suction means that is driven in conjunction with the mold opening operation of the mold device.
At least, the molding cycle from molding to removal of the molded product can be shortened and molding can be carried out efficiently, and the drive of the slide block can be related to the mold opening operation of the mold device, so that the molding cycle can be shortened and the molded product can be taken out. This eliminates the need to provide a means for moving the suction device, simplifies the entire device, and makes it possible to provide an inexpensive device.

Furthermore, in the present invention, suction ports are provided in the slide block so as to correspond to the plurality of molding sections provided in the mold device, so that the molded products molded in each of the molding sections can be sorted and taken out by suction. This aims to simplify the sorting work and facilitate the management of quality inspections, etc.
