Abstract
The utility model relates to a shaping casting mould of a diesel engine iron gear chamber cover, which comprises an upper mould 5 which is composed of the connection of an upper foundry flask 8, an upper mould sand mold 7 with a gear chamber cover shape, and a pouring opening 6, and a lower mould 2 which is composed of a lower mould sand mold 4 with a gear chamber cover shape, a movable mould core 9 and a lower foundry flask 1, wherein the upper and the lower moulds 5 and 2 are connected through a positioning column 3. The utility model is characterized in that a mold cavity 10 of a throttle regulator installing seat is firstly manufactured on the lower mould sand mold 4 of the lower mould 2, and the movable mould core 9 which is matched with the mold cavity 10 of the installing seat and is provided with a concave part 11 is secondly manufactured on the lower mould 2. when the utility model is installed, the movable mould core 9 is firstly arranged on the lower mould 2, the concave part 11 is covered o n the mold cavity 10 of the installing seat, an upper mould 5 is covered on the lower mould 2, the positioning column 3 is inserted into the lower mould 2 and an iron pressing plate is covered to carry out the casting. The manufacture of the mould is easy. Compared with an integral mould which is not provided with the movable mould core, the moulding speed of the utility model is improved by five to six times and the quality is also improved. If the mould is utilized to cast, the disability rate of the product and the production cost can be reduced.
Description
Affiliated technical field
The utility model relates to a kind of shape casting mould of diesel engine iron teeth gear chamber cover.
Diesel engine iron teeth gear chamber cover is because special-shaped complicated, and difficulty is big when mold is watered in making, work efficiency is slow, and sand mo(u)ld has damage just to cause foundry goods to scrap slightly, so product rejection rate is very high.Particularly there is a round bump throttle adjustment device switch mount pad upper end, can't the demoulding when manufacturing whole mould, as make active block and need again to make special trouble and difficulty with taking the photograph the son folder, careless slightlyly will break its parts.Because of manufacture difficulty is big, thereby consumption is just many man-hour, and the certified products qualification rate is also few, and the scrappage of product is increased, and production cost also increases.
Summary of the invention
The purpose of this utility model is in order to solve the deficiency described in the background technology, a kind of outer its middle casting mould that also has movable core rod of upper die and lower die that has to be provided.This mould is easy to manufacture, and manufacturing speed is fast, and the die quality of making is good, uses this die casting gear chamber cover can reduce scrappage, thereby reduces production costs.
The technical solution of the utility model is: a kind of shape casting mould of diesel engine iron teeth gear chamber cover, it comprises by cope, is the last model sand mold of gear chamber cover shape and patrix that the sprue gate connects to form and the counterdie of being made up of the following model sand mold that is the gear chamber cover shape, movable core rod and drag box.Upper and lower mould is connected by reference column.Be characterized in: produce throttle adjustment device mount pad die cavity earlier on the following model sand mold of counterdie, make a movable core rod that matches with the mount pad die cavity again, this activity core rod has the recess that matches with the mount pad die cavity.Earlier movable core rod is contained on the counterdie during installation, and its recess is covered on the mount pad die cavity.Patrix is also inserted good reference column on the counterdie upper cover then, and covering the foundary weight plate at last can cast.
The utility model has the advantages that: owing to adopt technique scheme to make this mould easy to manufacture, and compare with the whole mould that does not have movable core rod, molding speed improve 4-5 doubly and quality raising is also arranged, can reduce the scrappage of product greatly and reduce production costs greatly with this die casting.
