Abstract

The invention provides a floating mold clamping device for a sand-core accompanying support plate. The floating mold clamping device for the sand-core accompanying support plate is used for overturning a pattern drawing machine. The floating mold clamping device for the sand-core accompanying support plate comprises an upper roller way. Pairs of sand-core accompanying support plate locking mechanisms are symmetrically arranged at the left and the right of the front side and the right side of the upper roller way. Pairs of sand-core accompanying support plate floating mechanisms are symmetrically arranged at the left and right of the front side and the rear side of the upper roller way. The sand-core accompanying support plate floating mechanisms are provided with horizontally-arranged drive oil cylinders. The rear ends of the drive oil cylinders are hinged to backseats of oil cylinders on the upper roller way. The front ends of the drive cylinders are hinged to the upper ends of L-shaped floating clamping jaws. The middle portions of the floating clamping jaws are hinged to the clamping jaw supports fixed on the upper roller way. The lower ends of he floating jaws are provided with moving balls. The moving balls make contact with the lower plane of an upper plate of the sand-core accompanying support plate. The floating mold clamping device for the sand-core accompanying support plate has the advantages that the accuracy of die assembly of the sand-core accompanying plate and the sand core can be improved, the quality of the sand core is improved, and the production efficiency is improved.

Description

technical field [0001] The invention relates to casting molding equipment, in particular to a floating mold-clamping device for a sand core follow-up support plate used for an overturning mold lifting machine. Background technique [0002] In the process of demoulding the sand core with the flipping mold machine, the accurate positioning of the sand core and the sand core supporting plate for mold clamping is a key process step to ensure the quality of the sand core. In the current flipping mold lifting machine, the sand core follow-up pallet and the core box pallet are fixed on the respective roller tables by using the pallet locking mechanisms respectively arranged on the upper roller table and the lower roller table. The oil cylinder drives the upper roller table and the lower roller table to move to the center of the turning mold lifting machine to complete the mold clamping of the sand core and the sand core supporting plate. This mold closing method is prone to inaccu...
