Embodiment Construction

[0012] exist figure 2 In the shown embodiment of the case, the structure of the mold includes the die pads that are used in combination with each other in sequence, and the female die, and the upper die punch. The upper die punch is placed in the female die cavity at one end for applying powder samples. Pressed cylindrical object, the die pad is a disc-shaped gasket placed in the cavity of the female die opposite to the pressure end of the upper die punch. The upper die punch and die pad are not shown in the figure. The female die consists of two grooves The two-petal trough is composed of trough 1 and trough 6 respectively, the groove surface of trough 1 is opposite to the groove surface of trough 6, and groove 1 and curved One end of the arm 2 is connected, the trough 6 is connected to one end of the curved arm 5, and the remaining end of the curved arm 2 is connected to the remaining end of the curved arm 5 via a hinge mechanism 4 are mutually hinged, the material of the ...

Abstract

The invention relates to a mould for an easy-demoulding ceramic blank, which pertains to the field of ceramics molding and aims at solving the problem of hard demoulding of the existing ceramic mould. The mould comprises a die cushion, a female die and an upper punch which are sequentially and mutually sheathed and combined for use, and has the main points that: the female die consists of two groove-shaped objects, two groove surfaces which respectively belong to the two groove-shaped objects are oppositely arranged; the two groove-shaped objects are respectively connected with two ends whichrespectively belong to two bent arm-shaped objects; the rest two ends of the two bent arm-shaped objects are mutually articulated; the material of the bent arm-shaped object is magnetic conductivity material; and at least one bent arm-shaped object is wound with a magnet exciting coil at the bent arm. The mould can conveniently control the female die structure to fast switch between a magnetic attachment clench state and a power-down loose state, thus solving the problem of hard demoulding.

Description

technical field [0001] The invention relates to an easy-release ceramic billet molding die, which belongs to the field of B28B ceramic molding. Background technique [0002] Dry compression molding of powder is a high-efficiency molding method, which is widely used in the production of enterprises and the research and development experiments of related scientific research departments. [0003] In the process of carrying out a research and development experiment on silicon carbide ceramics, the designer of this case noticed that there is a defect in the forming mold used. The extension becomes more and more obvious. The reason is due to the high hardness of silicon carbide. Since the hardness of silicon carbide is second only to diamond, in the process of molding, it forms a strong scraping effect on the inner wall of the female mold. It doesn't take long for the wall surface of the inner wall of the female mold to be planed. In the area where the forming pressure effect is ...
