Description
Technical field
The utility model relates to a kind of casting mould of automatic molding.
Background technology
Precision-investment casting is a kind of casting technique of cutting less or not having cutting, is the technology of an excellence in the casting industry, and its application is very extensive.It is not only applicable to the casting of all kinds, various alloys, and the casting dimension accuracy of producing, surface quality are than other casting method height, even with other casting method be difficult to cast complexity, high temperature resistant, the foundry goods that is not easy to process, all can adopt precision-investment casting to cast.Therefore this advanced person's precision casting process is widely adopted in process industries such as aviation, automobile, lathe, boats and ships, internal combustion engine, gas-turbine, telecommunication instrument, weapon, medicine equipment and cutter, also is used for the manufacturing of workmanship simultaneously.Casting mould is the important process equipment that is used for making fusible pattern, and casting mould should satisfy condition: guarantee that the fusible pattern of making can meet the requirements of dimensional accuracy and surface roughness; Mounting or dismounting are convenient, and are light and handy, durable, are convenient to molding; Each parts of casting mould all should be easy to process, economical, reasonable; Smallclothes one type multi-cavity is to improve fusible pattern productivity ratio.In the actual production, when molding, have only vertical molding could guarantee the apparent size and the quality of product, the mould that convex design is especially arranged for the patrix bottom, manually molding is difficult to guarantee perpendicularity, and, need to rise earlier module during molding, the recurrence patrix for the mould of patrix band module, manually molding need have twice action, and production efficiency is lower.
Summary of the invention
For overcoming above-mentioned shortcoming, the purpose of this utility model is to provide a kind of casting mould of molding automatically.
In order to reach above purpose, the technical solution adopted in the utility model is: a kind of casting mould of automatic molding, and it comprises counterdie, upper die and lower die sprue gate, patrix sprue gate, counterdie has the inner chamber of depression; Patrix comprises first body, second body and be positioned between the two spring, offer first through hole on first body and with this first through hole coaxial and size greater than this first through hole from the counterbore of the first body end face to lower recess, has the outstanding projection that extends to form on the bottom surface of first body downwards, offer the position on second body, second through hole that size matches with projection, has connector on second body, this connector inserts in first through hole, connector has the end that radially becomes big, this end is positioned at counterbore, under free state, projection is positioned at the bottom surface that second through hole and its bottom do not exceed second body; When the first body pressurized contacted with second body, projection was passed second through hole and is exceeded the second body bottom surface.
Preferably, have first groove on the first body bottom surface, offer second groove on the end face of second body, insert respectively in first groove and second groove at the two ends of spring.
Preferably, when the first body pressurized contacted with second body, the end did not exceed the first body end face.
Preferably, first body has the end face that extends in horizontal plane.
Preferably, counterdie is provided with first connecting portion, and patrix is provided with second connecting portion.
Preferably, counterdie is provided with die lifter.
Owing to adopted technique scheme, the casting mould of the automatic molding of the utility model, by wax injector patrix first body is exerted pressure during production, first body and second body are compacted, and projection is stretched out the second body bottom surface thereupon, after casting is finished, wax injector rises, the bounce of spring is with the first body jack-up, and projection rises thereupon, has finished the automatic molding of module.This automatic molding mode had both guaranteed the perpendicularity of molding, and the time of contraposition has been improved production efficiency when having saved the time of artificial molding again and having adorned mould.

The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail, thereby protection domain of the present utility model is made more explicit defining so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that.
From the structural representation of the casting mould of accompanying drawing 1 automatic molding as can be seen, the utility model provides a kind of casting mould of automatic molding, it comprises, it comprises counterdie 10, patrix 20, counterdie sprue gate 41, patrix sprue gate 42, counterdie 10 is provided with first connecting portion 51, patrix 20 is provided with second connecting portion 52, in the present embodiment, first connecting portion 51 is for being positioned at the cylinder on relative two jiaos of counterdie 10 end faces, correspondingly, second connecting portion 52 is pegged graft counterdie 10 and patrix 20 like this for being positioned at the circular hole on patrix 20 relevant positions, take the direction of mould when having limited molding simultaneously, guaranteed the perpendicularity of molding; After counterdie 10 joined with patrix 20, counterdie sprue gate 41 combined with patrix 42 sprue gates, forms a complete sprue gate, links to each other with wax injector and finishes casting.
Counterdie 10 has the inner chamber 11 and the die lifter 12 of depression; Patrix 20 comprises first body 21, second body 22 and the spring 23 that is located at the two, have first groove 211 on the bottom surface of first body 21, offer second groove 221 on the end face of second body 22, insert respectively in first groove 211 and second groove 221 at the two ends of spring 23, with fixing spring 23 positions, simultaneously, when first body 21 and second body 22 compress, for spring 23 provides placement space.
Offer first through hole 25 on first body 21 and from first body, 21 end faces to the coaxial and size with first through hole 25 of lower recess counterbore 26 greater than first through hole 25, the bottom surface of first body 21 has the outstanding projection 27 that extends to form downwards, offer the position on second body 22, size and projection 27 second through holes 28 that match, on second body 22, be fixed with the connector 30 that is connected with first body 21, this connector 30 has the end 31 that radially becomes big, connector 30 positions, size matches with first through hole 25, and insert in first through hole 25, end 31 is positioned at counterbore 26, like this, counterbore 26 bottom surfaces can be blocked end 31, first body 21 and second body 22 can be relatively moved, and can not break away from.When first body, 22 pressurizeds contacted with second body 22, end 31 did not exceed first body, 21 end faces, avoids influencing wax injector first body 21 is exerted pressure; First body 21 has the end face that extends in horizontal plane, so that patrix 20 is stressed evenly during casting.
When casting, wax injector is exerted pressure to first body 21, and spring 23 shrinks, and when first body 21 contacted with second body 22, projection 27 was passed second through hole 28 and exceeded second body, 22 bottom surfaces, stretches in the inner chamber 11 of counterdie 10; When casting is finished, wax injector rises, under the effect of the restoring force of spring, first body 21 is by spring 23 jack-up, when first body 21 moves to extreme position, promptly end 31 is blocked by counterbore 26 bottom surfaces, and projection 27 is positioned at second through hole 28 and does not exceed second body, 22 bottom surfaces.
Above embodiment only is explanation technical conceive of the present utility model and characteristics; its purpose is to allow the people that is familiar with this technology understand content of the present utility model and is implemented; can not limit protection domain of the present utility model with this; all equivalences of doing according to the utility model spirit essence change or modify, and all should be encompassed in the protection domain of the present utility model.
