Piston ring cylindrical shell cast pattern die machine and method for manufacturing pattern die

Abstract

The invention relates to a piston ring cylindrical shell cast pattern die machine, comprising a machine frame, a sand core fixed template, a power plant, a movable template, a die and a sand core shell guide pole; wherein, the sand core fixed template is fixed at the top of the machine frame, the sand core fixed template is provided with at least a hole through which the die can move up and down; the die is a cylindrical cylinder which is fixed on the movable template; the guide pole is arranged at the center of the die, the guide pole is fixed on a guide pole locating plate of the machine frame; the movable template is arranged between the sand core fixed template and the guide pole locating plate, the movable template move up and down by the power plant. The invention further relates to a method for manufacturing the piston ring cylindrical shell pattern die, comprising the following steps: 1) uplifting the movable template and putting a slip flask in place; 2) pouring and pressing bonded sand; 3) lowering the movable template to a lower position; and 4) taking off the slip flask and obtaining the product. The invention solves the problems that the manufacturing process of the piston ring cylindrical shell pattern die is backward and the loss is great, and offsets the defects that the material cast by the prior art has bulky molecule and is not wearable.

Description

technical field [0001] The invention relates to a piston ring cylinder casting mold machine and a mold manufacturing method, in particular to an automatic molding piston ring cylinder casting mold machine and a mold manufacturing method, which are suitable for piston ring cylinders and cylinders. Oval cylinder. Background technique [0002] At present, the casting of piston ring materials is divided into two processes: cylinder body and single casting. The piston rings cast by single body are mostly used in machines with low temperature, while the piston rings cast by cylinder can be used in high temperature resistant occasions, especially suitable for diesel engines. and air compressors etc. But now the cylinder casting still adopts the traditional process to make the mold, which has obvious disadvantages: [0003] 1. The machining allowance of the cylinder is large, so that the addition of high-priced alloys is large; [0004] 2. The technology is backward and the produ...
