Opening liner bushing used in conjunction with die-casting fitting

Abstract

The invention discloses an opening liner bushing used in conjunction with a die-casting fitting. The opening liner bushing comprises a die-casting support, a hinged joint component, a sleeve, a die-casting chassis, a foot pad, a hand locking screw and a liner head, wherein the hinged joint component is arranged on the upper end of the die-casting support; the die-casting chassis is fixedly connected to the lower end of the sleeve; the foot pad is connected to the bottom of the die-casting chassis; the hand locking screw is used for positioning the foot pad; the lower end of the die-casting support is arranged on the sleeve through a liner bushing fixed part; the liner head is used for adjusting, locating and fastening the die-casting support and the sleeve; and the liner bushing fixed partis inserted into the side wall of the sleeve and is leaned against the interior of the liner head for engagement. A liner head body and a pedestal relatively move through the mutual inserting of theliner head body and the pedestal; the movement of the pedestal drives an adjusting rod to be inserted and move and up and down, thus, a connecting block and a positioning ball are driven to move up and down; the positioning ball moves up and down to be leaned against the wall of a triangular wedge, so that a sliding pin is squeezed out, a pressing block is driven to be squeezed out to increase theleaning force on the inner side wall of the sleeve for preventing the sleeve from shaking, and thus, the strength is ensured.

Description

technical field [0001] The invention relates to the technical field of machinery, in particular to an open bush used in conjunction with die castings. Background technique [0002] With the continuous development of the machinery industry, at present, the quick release method of this type of products all adopts die-casting and die-casting direct cooperation, and die-casting belongs to metal, after the cooperation, the gap is large, the product shakes seriously, and the gap is difficult to control during production. The rate is high, when there is a defect, one of the die castings will be scrapped as a whole, which will be a huge waste, and the output of qualified products will be low. In order to meet the shaking requirements, increase the output, and reduce the cost of the production process, this product is specially developed. Contents of the invention [0003] The purpose of the present invention is to provide an open bushing used in conjunction with die castings to s...
