Description
Technical field
The present invention relates to a kind of ceramic blank forming die that helps to solve demoulding difficult problem, belong to B28B forming process of ceramics field.
Background technology
Powder is carried out the dry method compression molding, is a kind of high-efficient molding method, and this method is widely used in the research and development experimental work of enterprise's production and related scientific research department.
This case designer is in carrying out the research and development experimentation of a relevant silicon carbide ceramics; notice; there is a kind of defective in employed shaping dies; this defective shows as demoulding difficulty after the blank moulding; this problem becomes obvious further along with the prolongation of shaping dies operating period; trace it to its cause; be due to the high rigidity of carborundum; because the hardness of carborundum is only second to diamond; in the process of compression molding; wall to the former inwall forms strong scraping action; how long do not disappear; the wall of former inwall is just by the one deck of shooting off; zone in briquetting pressure effect maximum; the zone between die-cushion and upper punch just; the wall of former inwall is deeper planed; and and then form one the circle depressed area; blank sample blocks after pressure forming is embedded in this zone and is difficult to the demoulding, and in this case, the demoulding will cause blank sample blocks elephant skin by force; broken; scrap; and; the demoulding also can make the sample piece of former inwall take off by force to be subjected to related serious grinding by way of the zone, to form horn mouth by force, scraps fast to former eventually; because the powerful planing effect that the high rigidity of carborundum is brought makes the problems referred to above thorny a bit.
Summary of the invention
Technical problem to be solved by this invention is at demoulding difficulty phenomenon after the above-mentioned blank moulding, to research and develop a kind of ceramic blank forming die that is easy to the demoulding.
The present invention solve the technical problem by following scheme, this scheme provides a kind of ceramic blank forming die that helps to solve demoulding difficult problem, this mould comprises the die-cushion that mutual sheathing in regular turn is used in combination, and, former, and, upper punch, described former is cylindric thing, described upper punch is that an end places and is used for cylinder that the powder sample is exerted pressure in the negative impression, described die-cushion is to place interior the exerting pressure with upper punch of negative impression to hold locational in opposite directions circular plate type pad, this case main points are, this former is made up of two lobe flute profile things, two groove surfaces that belong to two lobe flute profile things respectively are opposed in opposite directions, and, the structure of this mould also comprises six arms, four arms wherein are hinged from beginning to end and form the chain structure of sealing, the profile of the chain structure of this sealing is quadrangle, it is hinged with an end separately of two arms of remainder respectively that this profile is tetragonal chain structure a pair of relative drift angle wherein, the other end of the remainder separately of two arms of described remainder is connected with two lobe flute profile things respectively, and, the material of described arm is a magnetic conductive material, has at least an arm that is connected with the flute profile thing to be wound with magnet exciting coil in its surface.The art-recognized meanings of described die-cushion and former and upper punch is known in the forming process of ceramics technical field.Described magnetic conductive material refers to magnetic conductivity material preferably, and described magnetic conductive material is the carbon steel of soft iron, different phosphorus content and multi-element alloy steel or the like for example, and the art-recognized meanings of described magnetic conductive material is known.This case mould can further include some annexes, described annex is power supply for example, cable, and, be installed in the power switch on the circuit, or the like, described magnet exciting coil in this case mould structure can connect with power supply by cable and via power switch, when the described flute profile thing of two lobes involutory in opposite directions, and when connecting the current path of described magnet exciting coil and described power supply, form complete closed magnetic circuit, the described flute profile thing of two lobes relies on powerful magneticaction to each other, be interlocked mutually powerfully, and when contactor was in off-state, magneticaction disappeared, and the described flute profile thing of two lobes can transfer open state to from involutory state like a cork.
The structural requirement of this case has at least an arm that is connected with the flute profile thing to be wound with magnet exciting coil in its surface, and such structure just is enough to form the closed magnetic circuit that satisfies this case purpose.
Further the preferred construction scheme is, is all twining magnet exciting coil on the surface separately of two arms that are connected with two lobe flute profile things respectively.Such structure helps further to strengthen the described closed magnetic circuit of constraint, helps to offset the magnetic attraction loss that brings because of the disperse of magnetic line of force part.
Advantage of the present invention is, utilize the switch motion of the described power supply that is connected with described magnet exciting coil, just can control the described flute profile thing of two lobes, they are switched between mutual interlocking pattern of brute force and relaxed state fast, so, can carry out the powder operation of exerting pressure under the mutual interlocking pattern of described brute force, and the sample piece that will form through the operation of exerting pressure under described relaxed state takes out easily, this case mould has been dissolved the demoulding difficult problem after the described blank moulding.
