Abstract
The utility model relates to a casting device, particularly to a casting device for a brake drum. The casting device for a brake drum solves the problems of bad butting-superposing effect of upper and lower sand moulds, low working efficiency and the like existing in the present casting device for a brake drum. The casting device for a brake drum comprises an upper sand mould and a lower sand mould, wherein the top of the lower sand mould is closed; a pouring gate and a vent hole communicated with a brake drum casting mould space are disposed on the top of the upper sand mould; an upper location element and a lower location element are disposed on the tops of the upper sand mould and the lower sand mould respectively; and the positions of the upper location element and the lower location element are butted and superposed. Compared with the prior art, the casting device for a brake drum disclosed by the utility model is added with the location devices on the basis of the prior art, and the upper and lower moulds can be exactly and rapidly jointed, so that the operating environment of workers is improved, the production cost is decreased, the surface quality of castings is good, and the grade and quality of products are high.
Description
Technical field
The utility model relates to a kind of casting device, is specially a kind of brake drum casting device.
Background technology
The patent No. is 200820076691.3 to have put down in writing a kind of brake drum casting device, and this apparatus structure comprises resin shell core and following resin shell core, on last resin shell, is provided with exhaust outlet, cup, about bind round outside the shell core flexible sandbox arranged.The top of especially going up shell core and lower casing is a hollow form.This technical scheme has solved preferably that the labor strength that the traditional hand molding modeling causes is big, problem such as surface quality of continuous castings is poor, production efficiency is low, and yield rate is low.But in actual use, the technical staff still feels and is embodied in the some shortcomings part; Last drag sheel accurately butt joint is relatively required great effort, after especially mo(u)ld bottom half fastens on this kind casting device, outside more flexible sandbox being wrapped in; Can accurately agree with between the sand mold up and down, bend over shell interface is up and down examined, if after flexible sandbox loaded onto; Basically can't judge whether shell core accurately docks up and down, has wasted operating efficiency, and cause the defect rate of product to rise.
Summary of the invention
Problems such as the utility model is in order to solve the involutory weak effect of sand mold up and down that existing brake drum casting device exists, inefficiency and a kind of brake drum casting device is provided.
The utility model is realized by following technical scheme; A kind of brake drum casting device; Comprise sand mold, following sand mold, the top of last sand mold, following sand mold is a closed, is provided with sprue gate and steam vent with brake drum casting mold spatial communication at the top of last sand mold; The top of last sand mold and play sand mold be respectively equipped with on keeper and following keeper, the described keeper of going up docks coincidence with following locating piece position.
Described upward keeper is positioning sleeve or backstay, and described keeper down is positioning sleeve or backstay.Under the sand mold base being installed down, outside last sand mold, be provided with sandbox, connect through fastening bolt between sandbox and the base.
So, in the time of this device of assembling, directly connect down sand mold and snap together, whether keeper overlaps with following keeper through directly observe upward from the top then, can judge whether sand mold accurately stitchs together up and down.A large amount of energy and times can be practiced thrift like this, the qualification rate of product can be enhanced productivity and improve very like a cork.
Compared with prior art, the utility model has increased positioner on the basis of existing technology; Make accurately amalgamation fast between the mo(u)ld bottom half; And between last sand mold and sandbox, do not use any filler, and directly use the iron sheet sandbox that whole sand mold is wrapped up, connect through bolted; Alleviate workload, improved production efficiency; Improved workman's operating environment, reduced production cost, sand using amount is little, the saving of labor, save time, the molten iron utilization rate is high; Casting section thickness is even, good dynamic balance, and safety coefficient is high, and surface quality of continuous castings is good, and the product specification quality is high.
Description of drawings
Fig. 1 is the structural representation of the utility model
Fig. 2 is the A-A profile of Fig. 1
Fig. 3 is the left view of Fig. 1
Among the figure: keeper under sand mold, 3-sprue gate, the last keeper of 4-, 5-steam vent, 6-sandbox, 7-case handle, 8-fastening bolt, 9-base, 10-brake drum casting mold space, the 11-under the last sand mold of 1-, the 2-.
The specific embodiment
Meaning as shown in Figure 2; A kind of brake drum casting device comprises sand mold 1, following sand mold 2; The top of last sand mold, following sand mold is a closed; Be provided with sprue gate 3 and steam vent 5 with brake drum casting mold space 10 UNICOMs at the top of last sand mold 1, the top of last sand mold 1 and play sand mold 2 be respectively equipped with on keeper 4 and following keeper 11, describedly go up keeper 4 and coincidence is docked in following keeper 11 positions.Described upward keeper 4 is positioning sleeve or backstay, and described keeper 11 down is positioning sleeve or backstay.Through the accurate cover between positioning sleeve and the backstay with, perhaps docking between positioning sleeve and the positioning sleeve promptly can guarantee to dock tight.
At following sand mold base 9 is installed for 2 times, outside last sand mold 1, is provided with sandbox 6, connect through fastening bolt 8 between sandbox 6 and the base 9.Meaning as shown in Figure 3, described fastening bolt 8 one ends are hook-shaped, are hooked on the protrusion position of base 9, the other end is connected with sandbox through nut.
The following sand mold 2 that will make earlier is placed on the base 9; And then be placed on down the last sand mold 1 that makes on the sand mold 2, and it is lumped together through keeper, will go up sand mold, time sand mold and base with fastening bolt then and tightly link together; Accomplish mould assembling to this, promptly pourable.
