Description
Technical field
The present invention relates to metal material casting field, particularly relate to a kind of molding sand mold compacting device.
Background technology
Development and the progress of science and technology along with society; people to the protection of environment and energy-saving and emission-reduction particularly development to modern automobile industry have higher requirement; automobile casting just develops towards lightweight, thin-walled property direction; realize automobile casting lightweight, thin-walled property it is crucial that improve further the degree of packing of the casting mold producing automobile casting, this just requires that the mo(u)lding equipment of modernization has the most advanced molding sand mold compacting device.The present invention, to promoting the development of mo(u)lding equipment of modernization, particularly improves the degree of packing of the casting mold producing automobile casting, it is achieved automobile casting lightweight, thin-walled property are significant.
Molding sand mold compacting device is the critical component in the mo(u)lding equipment of modernization, its compacting effect directly affects the quality of automobile casting, in " development of Airflow Squeeze Moulding Process " literary composition, (Cai Qihao writes, " Chinese Foundry equipment and technology " the 5th phase in 1999), disclose the development of Airflow Squeeze Moulding Process the most both at home and abroad, Airflow Squeeze Moulding Process described in article refers to the molding sand mold compacting device that stream pressure (or gas shock) consolidation mechanism and multiple contact system for compacting combine, and its principal organ's pattern sees Figure of description 6 to Fig. 9.
Theoretical according to stream pressure (or claiming gas shock reality sand or static pressure reality sand) consolidation, the principal element affecting molding sand compacting effect is the Specifeca tion speeification " barometric gradient " of Air compacting sand mechanism, i.e. gas shock sand densifying mechanism under pulse valve with sandbox pre-fill frame upper space moment produce pressure and generation this pressure required time ratio, and one of key factor affecting barometric gradient is exactly, and the size of sandbox upper space volume is (see " jiangxi Palytechnic Univ.'s journal " second phase in 1988 " gas shock sand densifying mechanism and the research of Specifeca tion speeification " author: Geng Mao Peng Zhouliwu road light, other key factor affecting barometric gradient be have also been made and is discussed in detail by this article).The subject matter that above-mentioned static press moulding mechanism exists is: the sandbox pre-fill frame upper space volume of these moulding machines is excessive, the pulse control valve of single gas shock sand densifying mechanism is typically the most directly opened in the top of sandbox pre-fill frame, make its upper space minimum, barometric gradient can reach maximum, real sand effect is best, and air consumption is the most minimum.And the real sand device of the static press moulding recited in above-mentioned, the static press device that the molding sand mold compacting device that i.e. stream pressure sand densifying mechanism and multiple contact system for compacting combine is referred to as the most now, designer is not in order to affect the compaction actions of multiple contact system for compacting, its pulse control valve is all disposed within the top of multiple contact mechanism, so space of multiple contact mechanism becomes the passage of Air compacting sand process, thus expand under pulse valve the volume with sandbox pre-fill frame upper space, thus reduce the pressure gradient of Air compacting sand mechanism, thus had a strong impact on the effect of Air compacting sand.Particularly KW Static Pressure Molding Machine, both sides on the top of multiple contact mechanism, it is provided with two pulse control valve, two the tracheas the thickest that are provided with further below at two valves are passed through multiple contact cavity, the most significantly expand the volume of sandbox pre-fill frame upper space, reduce further its pressure gradient, air consumption is the biggest.Another problem of KW Static Pressure Molding Machine is to implement consolidation by two pulse control valve from both sides to the molding sand pre-fill frame, owing to the mechanical damping effect of two valves can not be identical, two pulse control valve are made to be difficult to accomplish high level of synchronization, easily make the movement disorder of entrance pre-fill frame air-flow, have a strong impact on the effect of Air compacting sand.
Summary of the invention
It is an object of the invention to solve the problems referred to above, it is provided that a kind of molding sand mold compacting device.
In order to realize the purpose of the present invention, the technical solution used in the present invention is:
A kind of molding sand mold compacting device, this device is body structure, casing is divided into top gas bag casing and bottom multiple contact mechanism casing by first order valve curtain, first order valve curtain has first order valve opening connection gas bag casing and multiple contact mechanism casing, it is provided with channel valve in air drum tank body, channel valve opens and closes first order valve opening, gas bag casing is provided with air inlet pipe, in multiple contact mechanism case body, multiple contact mechanism is set, there is second level valve curtain at multiple contact mechanism box bottom and have the second level valve opening of several and multiple contact authority match, multiple contact mechanism opens and closes second level valve opening, multiple contact mechanism casing is provided with exhaustor.
Multiple contact mechanism includes oil cylinder mechanism, contact stem, contact, oil cylinder mechanism controls contact by contact stem and moves, contact is set to the outside stretching out second level valve curtain at multiple contact mechanism casing, contact opens and closes second level valve opening the outside of multiple contact mechanism casing, in multiple contact mechanism, casing bottom margin one circle is provided with sealing flange, and sealing flange height is more than the endface position of contact foot when closing second level valve opening.
Also including that pre-filling frame, sandbox, template, template frame, lifting mechanism, above-mentioned parts are sequentially arranged in multiple contact mechanism lower box, the frame edge of pre-filling frame docks with sealing flange.
The beneficial effects of the present invention is: 1, the present invention is minimum with the channel space between below up to second level valve curtain at pre-filling frame.
