The technical solution of the utility model is; A kind of heavy-duty car axle housing integral core cold-box mould with following structure is provided: it comprises mould bases, core box body, penetrates the sand plate, the air blowing plate; Saidly penetrate the top that sand plate and air blowing plate are arranged on the core box body; Described core box body comprises core box and following core box, and said going up on core box and the following core box is equipped with two corresponding mud core cavitys; It also comprises upper plate and lower roof plate, and described upper plate is arranged on the core box top, and upper plate is provided with plunger tip mechanism, described lower roof plate and the bottom flexible connection of following core box, and lower roof plate is provided with down plunger tip mechanism; Said down core box is provided with that piece is taken out in a plurality of activities and a plurality of cylinders that piece moves are taken out in the driving activity.
After adopting above structure, the utility model heavy-duty car axle housing integral core cold-box mould compared with prior art has the following advantages: this heavy-duty car axle housing integral core cold-box mould adopts goes up the lower open die structure; And owing on following core box, be provided with two mud core cavitys; And design the pumping mode action that piece is taken out in a plurality of cylinder completion activities, so its coremaking labour intensity is low, basic about 70 seconds moulds; And a mould two cores, production efficiency is high; The mud core blank quality of making is evenly full, highly polished, quality is good.
As preferably; The said plunger tip mechanism of going up comprises the upper plate plunger tip limited post that is fixedly connected on the upper plate; The spacing motion bar of the upper plate of matched in clearance in last core box; The lower end of described upper plate plunger tip limited post and the upper end of the spacing motion bar of upper plate offset, and the lower end abutment of the spacing motion bar of said upper plate is on following core box top.When the mud core solidifies the upper and lower core box die sinking in back; Upper plate presses down; The lower end of upper plate plunger tip limited post presses down the upper end of the spacing motion bar of upper plate, and the lower end of the spacing motion bar of upper plate pushes against down the core box top, goes up core box simultaneously to rising; After upper plate plunger tip limited post ejects 20 millimeters downwards, on last core box, move, thereby make core box break away from core box down.
As preferably, said plunger tip mechanism down is meant and is connected with a plurality of plunger tip bars down on the said lower roof plate, is provided with the through hole of the corresponding one by one and matched in clearance of a plurality of and following plunger tip bar in the mud core cavity of said core box down.When core box was in the plunger tip station instantly, the piece pumping mode was taken out in the air cylinder driven activity on the following core box, and to rising, following plunger tip bar upper end ejects the mud core in the mud core cavity to lower roof plate, gets core then along suspension rod then.
As preferably, be fixedly connected with upper plate plunger tip guide finger on the said upper plate, last core box is provided with the pilot hole with upper plate plunger tip guide finger matched in clearance.
As preferably, said lower roof plate is connected bottom following core box through suspension rod, and lower roof plate is provided with the suspension rod installing hole with the suspension rod matched in clearance.
