Fig. 1 is a schematic structural view of a preferred embodiment of the present invention.
Detailed Description
The present invention will be described in detail with reference to fig. 1, and the exemplary embodiments and descriptions of the present invention are provided to explain the present invention, but not to limit the present invention.
In the implementation process, the titanium dioxide powder material can be sintered into a square shape by hot pressing, so that the upper and lower pressure heads of the die are correspondingly square. To square upper and lower pressure head, its two relative sides can adopt the utility model discloses a structure of positive inclined plane and chamfer, two other relative sides also can adopt and this same structure, also can adopt other structures to prevent to extrude, directly set up baffle etc. like two other relative sides. The present invention will be described in detail below with reference to two opposite sides as an example, and the other two opposite sides can be referred to and executed by adopting such a structure.
The utility model discloses a mould includes square upper pressure head 1 and lower pressure head 2 with this upper pressure head complex, is equipped with titanium white powder material 3 between the upper and lower pressure head, the shaping of upper pressure head bottom surface both sides wall has chamfer 11, the shaping of both sides wall that the lower pressure head top surface corresponds has positive inclined plane 21, be equipped with chamfer and positive inclined plane complex wedge 4 outside upper and lower pressure head; the wedge-shaped block is provided with a transmission mechanism 5, the transmission mechanism is connected with an outer mold 6 positioned on the side surface of the titanium dioxide powder material, and the wedge-shaped block drives the transmission mechanism to drive the outer mold to tightly abut against the side surface of the titanium dioxide powder material. The utility model adopts the matching mode of the wedge block and the inclined plane, on one hand, even if the titanium dioxide powder material is pressed to be very thin during hot pressing, the wedge block can not obstruct the movement of the pressing head, because under the action of the downward pressure or the upward pressure of the pressing head, the wedge block can move horizontally outwards to reduce the distance between the upper pressing head and the lower pressing head; even if the wedge-shaped block moves outwards horizontally, the transmission mechanism can also tightly support the outer die, so that the extrusion of materials is prevented; on the other hand, the wedge-shaped block is horizontally moved inwards by applying force from the outside to enlarge the distance between the upper pressure head and the lower pressure head so as to facilitate the die unloading, and at the moment, the transmission mechanism can continuously support the outer die to prevent the interference on the hot-pressed material during the die unloading, thereby further ensuring the quality of the material. In general, the wedge block cannot move outwards, and the wedge block can move outwards only when the titanium dioxide powder material needs to be pressed to be thin, but the wedge block can not move under the condition that the design is carried out according to the size of the material needing to be pressed.
Particularly, the wedge is cavity form, and this wedge inner chamber is provided with the drive head, actuating lever one end is connected with this drive head, and the other end wear out the wedge inner chamber with the external mold is connected. The wedge-shaped block can drive the driving head, the driving rod and the outer die to move. An inverted wedge surface 41 opposite to the wedge surface of the wedge block is formed in the wedge block, and two side surfaces of the driving head are attached to the inverted wedge surface. On one hand, the design can ensure that the outer die has enough thrust to tightly abut against the edge of the titanium dioxide powder material when the wedge block drives the driving head and the driving rod to move inwards; on the other hand, the contact area between the driving head and the wedge-shaped block is large, so that the driving head can be prevented from being damaged by the upper pressure or the lower pressure of the upper pressure head and the lower pressure head acting on the wedge-shaped block. Preferably, a compression spring 7 is arranged between the inner wall of the wedge block and the driving head. Therefore, even if the wedge-shaped block moves outwards, the compression spring has enough elasticity to ensure that the driving head and the driving rod enable the outer die to tightly abut against the edge of the titanium dioxide powder material.
Preferably, a corner groove 8 is formed between the inclined plane at the outer side of the upper pressure head and the inclined plane at the outer side of the lower pressure head and the plane for receiving the titanium dioxide powder material, the inner side surface of the outer die is of a planar structure, and the planar structure is tightly attached to the groove walls of the two corner grooves corresponding to the upper pressure head and the lower pressure head. In the implementation process, the height of the outer die is smaller than the sum of the heights of the two grooves, but is larger than the thickness of the hot-pressed material, so that the outer die is ensured not to interfere with the hot pressing of the pressure head. The utility model discloses a design of corner recess can guarantee on the one hand that the external mold pastes tight cell wall in order to support tight titanium white powder material edge, and on the other hand has the guide effect in addition, promptly in hot pressing process, when the pressure head has not contacted titanium white powder material yet, promotes the cell wall that the external mold made its two corner recesses of contact earlier through the wedge, and the staff just can know the wedge and has moved in place this moment, can stop promoting the wedge.
The above embodiments are provided only for the purpose of illustration, and not for the purpose of limitation, and those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and therefore all equivalent technical solutions should also fall within the scope of the present invention.
