Vertical type take out device for injection molding machines

Claim 1

A vertical type automatic take-out device for injection molding machines including: a. a base mounted on the injection molding machine; b. a sliding member mounted on said base so as to slide in a first direction and in a second direction opposite thereto; c. a support extending upwardly from said sliding member; d. a head mounted on the upper portion of said support and slidable along said support for adjustment of the height of said head; e. a main shaft penetrating said head and projecting therefrom in said first direction; f. a swing member pivotally mounted on said main shaft; g. a swing shaft arranged in parallel with said main shaft and penetrating said swing member so as to project therefrom in said first direction; h. a combination of a first cylinder pivotally connected with said head and a first piston rod means inserted into said first cylinder and connected with said swing shaft so as to rock said swing member together with said swing shaft by the operation of said first cylinder and first piston rod; i. a holder penetrated by said main shaft and swing shaft and slidable along said main and swing shafts; j. a guiding rod arranged in parallel with said main shaft and projecting from said head in said first direction; k. a sliding block means receiving said holder and mounted on said guiding rod so as to slide lengthwise thereof; l. a combination of a second cylinder normally substantially vertically held by said holder and a second piston rod means inserted into said second cylinder so as to move through said second cylinder; m. a combination of a third cylinder mounted on said head in parallel with said guiding rod and a third piston rod means inserted into said third cylinder so as to move along said guiding rod, said third piston rod being fixed to said sliding block; n. a first chucking mechanism comprising a first mounting member coupling said second piston rod to said first chucking mechanism, a fourth cylinder extending downwardly from said mounting member, a fourth piston rod means inserted into said fourth cylinder to move therethrough, a casing connected with said fourth cylinder, a first link connected with said fourth piston rod, a pair of second links having their upper ends pivoted to the respective ends of said first link, and a pair of third links having their middle portions pivotally supported on said casing and their upper ends pivoted to the lower ends of the respective second links wherein said third links hold a runner in the injection molding machine when said fourth piston rod is advanced from said fourth cylinder and releases said molded products when said fourth piston rod is retracted into said fourth cylinder; o. an extension member connected to said first mounting member so as to project therefrom in said first direction; p. a second chucking mechanism disposed in parallel with said first chucking mechanism, said second chucking mechanism comprising a combination of fifth cylinder mounted on said extension member and a fifth piston rod means inserted thereinto and movable in parallel with said fourth piston rod of said first chucking mechanism; a fixed frame including a first top member connected with said fifth cylinder and a pair of first vertical side members extending downwardly from both ends of said first top member; a vertically movable frame including a second top member connected with said fifth piston rod so as to move said movable frame together with the fifth piston rod, a pair of second vertical side members extending downwardly from both ends of said second top member, said vertically movable frame being so disposed as to face said fixed frame; a first crosswise movable frame so disposed as to face the opposite side of the fixed frame to that which faces said movable frame, said first crosswise movable frame comprising a pair of third vertical side members, first traverses fixed thereto, fourth links disposed slantwise with respect to the second vertical side members of said vertically movable frame and said first traverses of said first crosswise movable frame, each of said fourth links having one end pivoted to one of said second vertical side members and the other end pivoted to the corresponding first traverse, and fifth links each having one end pivoted to substantially the center of the corresponding fourth link and the other end pivoted to one of said first vertical side members of the fixed frame thereby moving said first crosswise movable frame across said fixed frame upon operation of said fifth piston rod; and a second crosswise movable frame comprising a pair of fourth vertical side members and mostly superposed on said first crosswise movable frame, second traverses fixed thereto, sixth links disposed slantwise with respect to said second vertical members of said vertically movable frame and said second traverses of said second crosswise movable frame, each of said sixth links having one end pivoted to the other of said second vertical side members and the other end pivoted to the corresponding second traverse and seventh links each having one end pivoted to the center of the corresponding sixth link and the other end pivoted to the other of said first vertical side member of said fixed frame thereby moving the second crosswise movable frame across said fixed frame upon operation of said fifth piston rod, whereby the third vertical side members of the first crosswise movable frame and the fourth vertical side members of the second crosswise movable frame hold molded products therebetween when the fifth piston rod is retracted in the fifth cylinder; and q. a detecting means mounted on said base for detecting the number of molded products taken out by said chucking means.
