Summary of the invention
the utility model object is: provide a kind of simple in structure, foundry goods form accuracy is high, and the few jaw foundry goods investment casting mold of manufacturing procedure.
the technical solution of the utility model is: a kind of jaw foundry goods investment casting mold, it is characterized in that, comprise base, be located at the material drag plate on described base, on, counterdie, be located at the gripper shoe between described base and described counterdie, be located at respectively described on, upper in counterdie, lower fuse and be located at described on, cast gate on the die joint of counterdie, in described counterdie, be provided with jaw pattern chamber, described jaw pattern is provided with interior fuse in chamber, described material drag plate is connected with described jaw pattern chamber by described lower fuse simultaneously, described cast gate is communicated with the opposite face of teeth in described jaw pattern chamber.
preferably, described upper and lower mould correspondence position is provided with two locating holes that are interconnected, and described upper and lower mould is fixedly connected with by the alignment pin matching with described two locating holes that are interconnected.
preferably, described base is all parallel with the die joint of described upper and lower mould with described material drag plate.
preferably, described lower fuse is vertical with the die joint of described upper and lower mould.
preferably, the die joint fit clearance of described upper and lower mould is less than or equal to 0.05mm.
preferably, the fit clearance of described lower fuse and described counterdie is less than or equal to 0.02mm.
preferably, the length of described cast gate is more than or equal to 10mm, the width of this cast gate is determined according to the size of foundry goods, the surface area of foundry goods is larger, the width of cast gate is also just larger, thereby in guaranteeing to ask, be full of jaw pattern chamber when very short, reach saturation degree and the surface roughness of foundry goods requirement, avoid producing the phenomenons such as shrinkage cavity and porosity.
the utility model jaw foundry goods is as follows with the concrete operation step of investment casting mold, first utilize Wire EDM equipment to process the jaw shape in required jaw pattern chamber, then punching is located, recycling Wire EDM equipment is divided into this casting mould, counterdie, after parting, pack upper fuse into patrix, lower fuse packs counterdie into, utilize Wire EDM equipment to process the required step surface of lower fuse, by lower fuse, material drag plate and jaw pattern chamber are coupled together again, then upper, the die joint of counterdie is as positioning datum, utilize grinding machine to fall the allowance of material drag plate, and guarantee the parallel of material drag board plane and die joint, and lower fuse and material drag plate, jaw pattern chamber vertical, and then by gripper shoe, whole casting mould is supported, recycling electric spark equipment processes the shape of small tooth, finally utilize alignment pin that upper die and lower die are fixed together.
the utility model has the advantages that:
1. the utility model can reach the desired surface roughness of foundry goods, and can guarantee significant dimensions and the form accuracy of foundry goods;
2. the utility model selects the opposite face of teeth in jaw pattern chamber that cast gate is set, and just can obtain desired shape after cutting away like this cast gate, need not carry out secondary operations again, and minimizing postorder is processed;
3. under the utility model utilization, fuse directly ejects casting out the foundry goods coming, to prevent from casting out next casting deformation.
