Driving working platform of sand shooting machine

Abstract

The invention provides a driving working platform of a sand shooting machine. The driving working platform comprises an annular track which is sealed, wherein a plurality of bearing frames are supported on the lower end surface of the annular track; a revolving platform is arranged at the center of the annular track; three bearing platforms protruding towards one side are uniformly distributed on the output outer annular surface of the revolving platform; two travelling wheels are arranged on the lower end surface of the outer part of each bearing platform; the bottom parts of the travelling wheels are arranged in a concave track on the upper end surface of the annular track in a supporting way; a centering and locking hole is formed in the outer side of each bearing platform; a revolving location seat is arranged in a position, corresponding to one working position, on the outer side of the annular track; the revolving location seat is provided with a radial location oil cylinder; a location cone is fixedly arranged on the output end of the radial location oil cylinder. According to the driving working platform provided by the invention, molds are respectively arranged on the annular track in the supporting way, so that mold structures can sequentially pass through a sand shooting working position, an air blowing working position and a drawing working position along a working driving direction, the preparation efficiency is greatly increased, and labor cost is reduced.

Description

technical field [0001] The invention relates to the technical field of the structure of a cold box core making machine, in particular to a driving workbench of a sand shooting machine. Background technique [0002] At present, there are mainly two types of mechanisms for the brake disc cold box core making machine, one is the bottom top type (the table drives the mold to lift), and the other is the top pressure type (the work table and the mold are perpendicular to each other without movement, the injection head, The air blowing frame and the upper pressure head move up and down to compress the mold), all of which are single-station core making, which has low production efficiency and requires a lot of labor costs. Contents of the invention [0003] In view of the above problems, the present invention provides a driving workbench for a sand shooting machine, which supports the molds on circular rails respectively, so that the mold structure passes through the sand shooting...
