Abstract
The utility model relates to the field of casting, in particular to a casting machine outer mold. A casting machine outer mold with an air hole comprises a connecting rod, a connecting body, an outer mold, a bolt, a pin hole jacketed core and a casting jacket, wherein the connecting rod is fixedly installed on the connecting body, the connecting body is fixedly installed on the outer mold through the bolt, and the pin hole jacketed core is arranged in the casting sleeve. The casting sleeve is arranged in the outer mold and is positioned through the pin hole jacketed core, a movable pin is further arranged on the casting machine outer mold, and the movable pin penetrates through the outer mold to contact with the casting sleeve and a casting. According to the casting machine outer mold with the air hole, the movable pin is arranged, the movable pin is firstly pulled out when a mold is opened, so gas tightness is destroyed, the mold opening force is lowered, and the breakage of the bolt and damage of the outer mold are prevented. The mold is protected, consumption of the mold is reduced, and equipment cost is saved.
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, two half modules about the counterdie of external mold 3 is divided into, two half modules, connected body 2 is fixedly linked by bolt 4 and external mold 3, and by connected body 2 direct pulls, mould opening force all concentrates on the bolt 4 that links to each other with external mold simultaneously by connecting rod 1, 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: the frictional force that mould self produces because of gravity when the power of foundry goods cover 7 generations when power of holding pin-and-hole cover core 5 tightly that foundry goods 6 contractions produce, foundry goods 6 outer wall condensation and in the external mold 3 and die sinking; In addition because external mold 3 and foundry goods cover 7 is the body of a sealing, thus when cast complete after foundry goods 6 along with temperature constantly reduces, cause foundry goods to overlap 7 interior generation certain vacuum degree because expanding with heat and contract with cold, this so that mould opening force further increase so that die sinking is unusually difficult.
In the existing this structure, bolt 4 bears above all simultaneously during die sinking, disposable external mold 3, pin-and-hole cover core 5 and foundry goods cover 7 are pulled out together, 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 producing is 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 with pore, is provided with a removable pin, at first extracts removable pin during die sinking, has so just destroyed air-tightness, has reduced mould opening force.
The utility model is achieved in that a kind of casting machine external mold with pore, comprise connecting rod, connected body, external mold, bolt, pin-and-hole cover core and foundry goods cover, described connecting rod is fixedly mounted on the connected body, described connected body is mounted by means of bolts on the external mold, described pin-and-hole cover core is arranged in the foundry goods cover, described foundry goods is set in the external mold and is located by pin-and-hole cover core, also is provided with removable pin on this casting machine external mold, and described removable pin passes external mold and contacts with foundry goods with the foundry goods cover.
Described removable pin is arranged on two half module junctions of external mold.
Described removable pin is square alignment pin.
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 band pore is provided with a removable pin, at first extracts removable pin during die sinking; so just destroy air-tightness, reduced mould opening force, avoided the fracture of bolt and the damage of external mold; protect mould, reduced mould consumption, saved equipment cost.
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 band pore.
Among the figure: 1 connecting rod, 2 connected bodies, 3 external molds, 4 bolts, 5 pin-and-holes cover core, 6 foundry goods, 7 foundry goods covers, 8 removable pins.
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.
Embodiment 1
As shown in Figure 2, a kind of casting machine external mold with pore, comprise connecting rod 1, connected body 2, external mold 3, bolt 4, pin-and-hole cover core 5 and foundry goods cover 7, described connecting rod 1 is fixedly mounted on the connected body 2, described connected body 2 is fixedly mounted on the external mold 3 by bolt 4, described pin-and-hole cover core 5 is arranged in the foundry goods cover 7, described foundry goods cover 7 is arranged in the external mold 3 by pin-and-hole cover core 5 location, also be provided with removable pin 8 on this casting machine external mold, described removable pin 8 passes external mold 3 and foundry goods cover 7 and contacts with foundry goods 6.
In the present embodiment, described removable pin 8 is arranged on two half module junctions of external mold 3, and removable pin 8 can also play the effect of alignment pin like this, so just can select square alignment pin as removable pin.
In addition, in the utility model, 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, during die sinking, the first step is extracted removable pin 8 first, outside like this air just enters into external mold 3 and foundry goods and overlaps gap between 7 and foundry goods 6 and foundry goods and overlap gap between 7 from pin-and-hole, and then pulling connecting rod 1, external mold 3 and foundry goods cover 7 are pulled out together, reduced needed mould opening force.
