Detailed Description
The following further describes the specific technical content of the invention with reference to the drawings and the embodiments:
referring to fig. 1 and 2, the riser ring manufacturing device for casting the casting of the injection molding machine comprises a frame, a workbench, an outer die, a core rod, a lifting table and a cylinder; the workbench is arranged on the frame; the core rod is connected in the outer die, and the bottom in the outer die is connected with a movable block capable of lifting; a cavity among the top surface of the movable block, the outer wall of the core rod and the inner wall of the outer die forms a riser ring cavity; the bottom of the movable block is connected with a vertical ejector rod; the shape of the movable block corresponds to the shape of the inner cavity of the outer die, and a through hole corresponding to the shape of the core rod is formed in the center of the movable block; the riser ring is provided with a plurality of cavities, the heights of the outer molds of the cavities are the same, and the lengths of the ejector rods are the same; the structural dimension specifications of the multiple riser ring cavities are in a plurality of series, and the difference of each specification is obtained by the difference of the structural dimension of the inner cavity of the riser ring cavity, the structural dimension of the shape of the core rod and the thickness dimension of the movable block (namely, the heights of the outer dies of the riser ring cavities of each specification are the same and the bottom surfaces of the outer dies are also flat seen from the shapes of the outer dies); each riser ring cavity is vertically positioned on the workbench; the workbench is provided with a hollow part, and each ejector rod penetrates through the hollow part; the lifting platform is arranged below the workbench, and a vertical guide mechanism is connected between the lifting platform and the workbench; the top surface of the lifting platform is propped against the ejector rod; the top surface of the lifting platform is propped against the ejector rod; the frame is connected with an air cylinder, and a piston rod of the air cylinder is connected with the lifting platform.
As shown in fig. 3, for the riser ring cavity with the same dimension, the outer mold is cuboid, parallel through holes are formed in two sides of the outer mold, and the axes of the through holes are horizontal; the riser ring cavities with the same specification are sequentially arranged along the axis direction of the through hole, and a screw rod penetrates through the through hole on the same side and is locked by a nut;
the surface of the workbench is connected with two vertical side brackets, and the screw rod is detachably connected between the two side brackets.
The riser ring cavities of the same specification are arranged in a row, and a plurality of rows of riser ring cavities of different specifications are mutually parallel. A plurality of groups of through holes are preset on the side support, and the outermost end of the screw rod extends into the through holes and is locked by a nut.
Because the lifting platform is a plane, and the bottom end of the ejector rod is propped against the lifting platform, in the horizontal direction, the position difference of the ejector rod does not influence lifting demoulding. The demoulding in the vertical direction is synchronously driven by the lifting platform.
The guide mechanism comprises a plurality of groups of corresponding guide rails; each guide rail is vertically connected to the bottom surface of the workbench; the lifting platform is provided with a through hole corresponding to the guide rail, the guide rail passes through the through hole, and the tail end of the guide rail is connected with a stop block.
When the engineering is realized, the connecting structure between the core rod and the outer die can be that the bottom of the core rod is connected with the bottom of the outer die through a plurality of horizontal cross rods.
