Embodiment 1
[0051] The composition and production of the coated sand mold: ①The composition of the mold: a total of 28 independent structural parts are assembled, which are the upper outer mold shell type 10, the lower outer mold shell type 11, and eight air inlet shells. Core 9, eight exhaust duct shell cores 16, two cooling water cavity solid cores 12, sprue cup 7, sprue 8, filter screen 3, horizontal-inner runner 13, two exhaust duct sides The solid core 14 of the core base and the solid core 15 of the lower core base on the side of the two exhaust passages; 2. The manufacturing method of 25 independent structural parts in the mold: there are three types of manufacturing, which are respectively shell molding, shell core manufacturing and Solid core production. Among them, the upper outer mold shell type 10 and the lower outer mold shell type 11 are made of shell molds: the templates of the upper half mold shell type and the lower half mold shell type are preheated to 180-220°C, and the...

[0057] The composition and production of the coated sand mold: ①The composition of the mold: a total of 16 independent structural parts are assembled, which are the upper outer mold shell type, the lower outer mold shell mold, four crankcase shell cores, two Valve lifter solid core, oil cooler solid core, cooling water cavity solid core, first cylinder side solid core, fourth cylinder side solid core, cylinder barrel solid core seat, sprue cup, sprue, filter ; ②Manufacturing of 16 independent structural parts of the mold: There are three types of manufacturing, which are shell mold making, shell core making and solid core making. Among them, the upper outer mold shell type and the lower outer mold shell mold are made of shell molds: preheat the templates of the upper outer mold shell mold and the lower outer mold shell mold to 200°C, and the coated sand will naturally fall into the preheated mold under the action of gravity. In the shell molding cavity formed by the single-sid...
