Abstract
The utility model relates to an oiling-capsule-type equal positive pressure die core, comprising an upper die core and a lower die core, which is characterized in that a rubber layer is arranged on the pressure face of the upper die core and the lower die core; an oiling capsule body is arranged in the rubber layer of the upper die core; a connecting oil sink is evenly distributed in the oiling capsule body; an oiling orifice and a drainage orifice are arranged in the oiling capsule body to the outside of the die core. The utility model has the advantages of having a uniform oil pressure, a smooth oil way, a fast adjustment response a great equal positive pressure performance in the capsule body; having no degrumming, no bulge, no oil leakage, but a long service life in the compression molding process of the raw bricks; eliminating the drawbacks of cutter bending, uneven end and cracks; removing all kinds of problems caused by the uneven mix feeding or inconsistent powder lot.
Description
(1) technical field
The utility model relates to the tile mould technical field, is specifically related to malleation core rods such as a kind of oiling capsule-type.
(2) background technology
General rubber combined ceramic die mainly is made up of base plate, buffer stopper, center and core rod at present, mould is when compression moulding, because cloth inequality or powder are inconsistent, be prone to phenomenons such as the adobe cutter is curved, concentric reducer, plane warping, crackle, concave edge, chimb.A kind of isostatic mold core by being provided with the oil groove of whole connections in the core rod body, and is provided with the pressure transmission part between oil groove and rubber layer, this core rod can make adobe when compression moulding stressed evenly, can solve the defective of common die.But, described isostatic mold core, because complex structure causes the difficulty of processing height, production efficiency is low; Its oil pressure is inhomogeneous, regulates slow; In the adobe pressing process, easily come unstuck, bulge, leakage of oil.
(3) summary of the invention
The purpose of this utility model is the malleation core rods such as a kind of oiling capsule-type that design at the deficiencies in the prior art, by improvement to core rod, in the rubber layer body, be provided with the oiling capsule body, can eliminate the defective that General Purpose Rubber ceramic die and malleation core rod such as common exist simultaneously.
Malleation core rods such as oiling capsule-type, comprise upper mold core and lower mold core, the pressure-bearing surface of upper mold core and lower mold core is provided with rubber layer, it is characterized in that being provided with the oiling capsule body in the rubber layer of upper mold core, be evenly equipped with the oil groove of connection in the oiling capsule body, the oiling capsule body is provided with pouring orifice and drain tap to the core rod outside.
The setting of described connection oil groove be according to the specification of adobe and area and fixed, oil groove can be strip and distribute, the distribution that also can be square also can be I-shaped distribution, is interconnected between the oil groove.
Described pouring orifice is a check valve, is used for not backflowing when the oiling capsule body injects hydraulic oil after moulding, and drain tap is a sealing screw.
Oiling capsule body in the rubber layer body owing to be communicated with the pressure transfer function that oil groove forms, if powder is inhomogeneous, can transmit the pressure that does not wait by being communicated with oil groove mutually, and the every bit pressure that is adjusted to adobe powder face is identical.
The malleation core rods such as oiling capsule-type that the utility model is designed, simple in structure, easy to process; Oil pressure is even in the capsule body, and oil circuit is smooth and easy, and conditioned reaction is fast, and is effective etc. malleation; In adobe compression moulding process, not come unstuck, not bulge, oil-proof, long service life, defectives such as the cutter that can eliminate adobe is curved, concentric reducer, crackle can be eliminated the inconsistent variety of issue that causes owing to cloth inequality or powder.

(5) specific embodiment
Present embodiment is the malleation core rods such as oiling capsule-type of rectangle tile mould, comprise upper mold core and lower mold core, the pressure-bearing surface of upper mold core and lower mold core is provided with rubber layer, be provided with oiling capsule body (3) in the rubber layer (2) of upper mold core (1), be evenly equipped with the oil groove (4) of connection in the oiling capsule body, the oiling capsule body is provided with pouring orifice (5) and drain tap (6) to the core rod outside.
The oil groove of present embodiment (4) is strip and distributes, and is interconnected between the oil groove.
Claims (3)
1, malleation core rod such as oiling capsule-type, comprise upper mold core and lower mold core, the pressure-bearing surface of upper mold core and lower mold core is provided with rubber layer, it is characterized in that being provided with the oiling capsule body in the rubber layer of upper mold core, be evenly equipped with the oil groove of connection in the oiling capsule body, the oiling capsule body is provided with pouring orifice and drain tap to the core rod outside.
2, malleation core rod such as oiling capsule-type according to claim 1 is characterized in that oil groove can be strip and distribute, and the distribution that also can be square also can be I-shaped distribution, is interconnected between the oil groove.
