Title:
MOLD APPARATUS FOR MOLDING RESIN
Document Type and Number:
Japanese Patent JP3936468
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide the subject apparatus reduced in its size or arranging floor area and fitted to energy saving and cost reduction by increasing the dust collecting efficiency of a dust collector by improving the structure of the changeover valve arranged to the duct route of the dust collector and highly efficiently collecting dust from a plurality of dust generating places by one dust collector.
SOLUTION: A changeover valve 37 fitted with a valve drive device 33 is arranged to the duct route connecting the respective suction ports provided in the vicinity of the respective dust generation places in an apparatus and a valve disc 39 is connected to the movable part 38 of the valve drive device 33 to be made possible to advance and retreat and formed into a conical trapezoidal shape made small in its diameter toward the leading end thereof by using an elastic member. The center line of the valve disc 39 is allowed to coincide with a movable direction and the center line of a duct on-off valve member receiving part 41 in which the valve member 39 is fitted at a time of closing.
