Abstract
The utility model discloses a kind of single bimodulus of casting for piston, it is characterised in that：Include mold I and mold II, the mold I connects casting gate with mold II by running channel, the mold I and mold II have separately included pedestal, shell I, shell II, it fans on the left side, the right is fanned and upper mold, the pedestal top is the space that shell I and shell II are surrounded, it is provided with annular table on the inner wall of the shell I and shell II, the left side fan connects lower semicircular cylinder by handle with the right fan and forms, the lower part of the semicylinder is recessed inwardly, boss is formed between top and lower part, the left side fan and the right fan are placed close to shell I and shell II respectively, at the boss engaging and the annular table, the upper mold is positioned between left side fan and the right fan.The utility model not only improved work efficiency, but also reduced rejection rate.
Description
Technical field
The utility model is related to casting for piston technical field, the single bimodulus of specially a kind of casting for piston.
Background technology
Piston is the key components and parts of engine, and with the fast development of automobile industry, the demand of piston is also got over
Come bigger.In piston casting, when casting specification is compared with piston as large as 80 or more ￠, an automatic single mould casting machine installation one
Single mode once produces 1 blank, is stablized with single mode production blank dimension, and casting is useless less, but inefficiency class produces 400 or so,
Utilization rate of equipment and installations is low.One bimodulus automatic casting machine, install a bimodulus, once produce 2 blanks, bimodulus casting ￠ 80 with
On piston blank size it is unstable, the place below bad demoulding, especially key seat, demoulding is difficult yielding, and casting is useless more.
Invention content
The present invention is directed to the above shortcoming, provides a kind of single bimodulus of casting for piston, not only improved work efficiency, but also
Reduce rejection rate.
The technical solution adopted by the present invention to solve the technical problems is：A kind of single bimodulus of casting for piston, includes mould
Tool I and mold II, the mold I and mold II connect casting gate by running channel, and the mold I and mold II have separately included bottom
Seat, shell I, shell II, left side fan, the right fan and upper mold, the pedestal top are the space that shell I and shell II are surrounded, institute
It states and is provided with annular table on the inner wall of shell I and shell II, the left side fan is fanned with the right connects lower semicircular cylinder by handle
Composition, the lower part of the semicylinder are recessed inwardly, and boss, the left side fan and the right fan difference are formed between top and lower part
It is placed close to shell I and shell II, at the annular table, the upper mold is positioned over left side fan and the right fan for the boss engaging
Between.
Further, the annular is set at 2/3rds of outer cover height from bottom to top, the position of the boss with
Annular table is adapted.
Further, the shell I of the shell I of the mold I, shell II and mold II, shell II are fixedly connected.
The beneficial effects of the invention are as follows：Single mode is changed to share single bimodulus of two single modes composition of a casting gate, both
Improve the utilization rate of equipment and installations of single mould casting machine, and working efficiency improves 2 times, mould inside be arranged two sides fan and on
Mould, the common making for completing piston blank, side fan top are respectively arranged to the handle of extraction, make the piston blank size of casting
Stablize, and be unlikely to deform, casts the rate of giving up and reduce 80% than bimodulus casting machine.
Description of the drawings
It is the structural schematic diagram of the utility model shown in Fig. 1；
It is the sectional view of the utility model shown in Fig. 2；
In figure：1- pedestals, the left sides 2- shells I, 3- shell II, 4- fan, the right 5- fan, 6- upper molds, 7- annular tables, 8- handles
Hand, 9- boss, 10- casting gates, 11- running channels.
Specific implementation mode
The present invention will be described in detail in the following with reference to the drawings and specific embodiments：
It as shown is the specific embodiment of the present invention, a kind of single bimodulus of casting for piston, includes mold I and mould
Have II, the mold I and mold II and casting gate 10 is connected by running channel 11 respectively, the mold I and mold II have been separately included
Pedestal 1, shell I2, shell II3, left side fan 4, the right fan 5 and upper mold 6,1 top of the pedestal are that shell I2 and shell II3 encloses
At space, be provided with annular table 7 on the inner wall of the shell I2 and shell II3, the left side fan 4 and the right fan 5 are by handle 8
Lower semicircular cylinder composition is connected, the lower part of the semicylinder is recessed inwardly, and boss 9 is formed between top and lower part, described
Left side fan 4 and the right fan 5 are placed close to shell I2 and shell II3 respectively, described at the engaging of the boss 9 and the annular table 7
Upper mold 6 is positioned between left side fan 4 and the right fan 5.The annular table 7 is set to 2/3rds of outer cover height from bottom to top
Place, position and the annular table 7 of the boss 9 are adapted.Shell I2, the shell II3 of the mold I and the shell I2 of mold II,
Shell II3 is fixedly connected.
When using the utility model, by mold integral installation on single mould casting machine, shell I2 and shell II3 are in separation
Left side fan 4 and the right fan 5 are mounted on shell I1 and shell II3 by state, and the boss 9 of left side fan 4 and the right fan 5 blocks respectively
Close shell I2, shell II3 annular table 7 on, the propulsion device on single mould casting machine inwardly pushes away shell I2 and shell II3
Into, engage with pedestal 1, shell I2 and shell II3 also have the gap therebetween, then, from top by upper mold 6 mounted on the left side fan
Between 4 and the right fan 5, propulsion device again inwardly promotes shell I2 and shell II3, at this point, shell I2, left side fan 4, upper mold
6, the right fan 5, shell II3 are close together, and then, from the casting gate 10 at middle part, inwardly casting liquid, casting liquid pass through running channel 11
It flows into mold, after standing a period of time, upper mold 6 is taken out, then, manually take out left side fan 4 and the right fan 5, by mold I
It is detached with the shell I2 of mold II and shell II3, you can obtain two piston blanks.
Certainly, above description is not limitation of the present invention, and the present invention is also not limited to the example above, this technology neck
The variations, modifications, additions or substitutions that the technical staff in domain is made in the essential scope of the present invention should also belong to the present invention's
Protection domain.
