Abstract
The utility model relates to the field of casting and particularly relates to a casting machine external mold. The casting machine external mold with a buffered die sinking force comprises a connecting rod, a coupling body, an external mold, a bolt and a pin hole sleeve core, wherein one end of the connecting rod is fixedly mounted on the outer end face of the coupling body, and the other end of the connecting rod is connected with an output rod of an oil cylinder; the coupling body is fixedly connected with the external mold through the bolt; the casting machine external mold also comprises an elastic buffering piece; and one end of the elastic buffering piece is fixedly mounted on the inner end face of the coupling body, and the other end of the elastic buffering piece passes through the external mold and is fixedly connected with the pin hole sleeve core. The casting machine external mold with the buffered die sinking force has the beneficial effects that as the elastic buffering piece arranged at the axis of the coupling body is connected with the pin hole sleeve core, at the initial stage of die sinking, the elastic buffering piece can be stretched to buffer the pulling force borne by the bolt, thus avoiding bolt rupture or external mold damage.
Description
Technical field
The utility model relates to the casting field, relates in particular to a kind of casting machine external mold.
Background technology
For metal mold aluminum cast member, such as traditional casting machine mold-opening structure of aluminium piston as shown in Figure 1, connecting rod 1 is by connected body 2 direct pull external molds 3, mould opening force all concentrates on the bolt 4 that links to each other with external mold simultaneously, because being subject to the restriction of connected body 2 sizes and external mold 3 structures, bolt 4 can not surpass a pair of usually.This mould opening force mainly is divided into three parts: mould self is because of the frictional force of gravity generation when the power that produces with external mold when foundry goods 6 shrinks the power of holding pin-and-hole cover core 5 tightly that produces, foundry goods 6 outer wall condensation and die sinking.When foundry goods 6 hour can pull open external mold 3 by the stressed of bolt 4 smoothly, but when the larger needed mould opening force of foundry goods of production was excessive, the phenomenons such as bolt abruption, thread stripping or external mold damage just may appear in bolt 4.For this mould damaged condition, solution only has a kind of, and the repair welding external mold is also repaired internal thread, and the common material of mould is cast iron, this cast iron welding is very difficult, simultaneously owing to being subject to the little and stressed large restriction of die sinking in locus, so that the die life of fixing is very limited; In addition, all be a whole set of moulding during Mould Machining, there is not versatility, once damage an arbitrarily part, a whole set of mould will be scrapped, the required strength of die sinking greatly also will need more large-scale hydraulic jack, further improved production cost.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of casting machine external mold that cushions mould opening force, link to each other with pin-and-hole cover core by the resilient snubber that is arranged on place, connected body axle center, in the die sinking starting stage, the pulling force that the buffering bolt bears has been avoided the fracture of bolt or the damage of external mold.
The utility model is achieved in that a kind of casting machine external mold that cushions mould opening force; comprise connecting rod, connected body, external mold, bolt and pin-and-hole cover core; described connecting rod one end is fixedly mounted on the outer face of connected body; the other end of connecting rod links to each other with the oil cylinder take-off lever; described connected body is fixedly linked by bolt and external mold; this casting machine external mold also comprises resilient snubber; described resilient snubber one end is fixedly mounted on the inner face of connected body, and the other end of resilient snubber passes external mold and pin-and-hole cover core is fixedly linked.
Described resilient snubber is helical spring.
Described bolt has two, and two bolts are symmetricly set on the two ends of connected body.
The casting machine external mold of the utility model buffering mould opening force, link to each other with pin-and-hole cover core by the resilient snubber that is arranged on place, connected body axle center, in the die sinking starting stage, resilient snubber can be stretched, the pulling force that the buffering bolt bears has been avoided the fracture of bolt or the damage of external mold.
Description of drawings
Fig. 1 is existing casting machine mold-opening structure schematic diagram;
Fig. 2 is the casting machine cast outer mold structure schematic diagram of the utility model buffering mould opening force.
Among the figure: 1 connecting rod, 2 connected bodies, 3 external molds, 4 bolts, 5 pin-and-holes cover core, 6 foundry goods, 7 resilient snubbers.
The specific embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only are used for explanation the utility model and are not used in the scope of the present utility model that limits.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model statement, these equivalent form of values fall within the application's appended claims limited range equally.
As shown in Figure 2; a kind of casting machine external mold that cushions mould opening force; comprise connecting rod 1, connected body 2, external mold 3, bolt 4 and pin-and-hole cover core 5; described connecting rod 1 one ends are fixedly mounted on the outer face of connected body 2; the other end of connecting rod 1 links to each other with the oil cylinder take-off lever; described connected body 2 is fixedly linked by bolt 4 and external mold 3; this casting machine external mold also comprises resilient snubber 7; described resilient snubber 7 one ends are fixedly mounted on the inner face of connected body 2, and the other end of resilient snubber 7 passes external mold 3 and is fixedly linked with pin-and-hole cover core 5.
In the utility model, described resilient snubber 7 is helical spring.
Described bolt 4 has two, and two bolts 4 are symmetricly set on the two ends of connected body 2.
Use the utility model to cast, in the die sinking starting stage, resilient snubber 7 can be stretched, will share like this foundry goods 6 and shrink the power of holding pin-and-hole cover core 5 tightly that produces, at this moment, mould self has reduced the pulling force that bolt 4 connecting portions bear because of the frictional force that gravity produces when 4 usefulness of bolt are born foundry goods 6 outer wall condensation and when the power that produces of external mold and die sinking, has avoided the fracture of bolt 4 or the damage of external mold.
