Abstract
The utility model provides a double-layer glue type isopiestic mold core. A bearing working surface of the mold core is covered with a double-layer rubber layer, the surface layer is a hard rubber layer and the base layer is a flexible rubber layer. The flexible rubber layer is substituted for an oiling capsule body to simplify the structure of the mold core, stabilize the performance and enhance isopiestic pressure effect. The defects of the green bricks such as knife curve, concentric reducer, crack, interlayer, etc., can be eliminated, various problems resulted from the nonuniformity of the cloth or the disparity of the powder can be eliminated, and thus, the quality of the green bricks can be ensured.
Description
Technical field
The utility model relates to the tile mould technical field, is specifically related to a kind of double-deck glue formula isobaric mold insert.
Background technology
At present general rubber combined ceramic die mainly is made up of base plate, center and core rod, is coated with individual layer vulcanie layer on the pressure-bearing working face of core rod, because cloth inequality or powder are inconsistent, the repressed brick base is prone to phenomenons such as concentric reducer, cutter are bent, interlayer.A kind of advanced malleation core rods such as oiling capsule-type, in the rubber layer of core rod, be provided with the oiling capsule body, 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, this core rod makes adobe stressed even when compression moulding, can solve the defective of common die.But still there is deficiency in malleation core rods such as above-mentioned oiling capsule-type: the one, and the size of core rod oil pressure is difficult to control; The 2nd, the easy leakage of oil of oil sealing.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of stable performance is provided, makes simple, as to guarantee unfired brick quality double-deck glue formula isobaric mold insert.
The technical scheme that realizes the utility model purpose is:
Double-deck glue formula isobaric mold insert comprises the core rod body, is coated with rubber layer on the pressure-bearing working face of core rod body, and it is characterized in that: described rubber layer has bilayer, and the top layer is the vulcanie layer, and bottom is the soft rubber layer.
The hardness of described vulcanie layer is between 90 ° to 97 °, and the hardness of described soft rubber layer is between 20 ° to 30 °.
The utlity model has following advantage: 1, the designed double-deck glue formula isobaric mold insert of the utility model, substitute the oiling capsule body with the soft rubber layer, make become very simple of the structure of its core rod, thereby manufacture craft is simple, performance is highly stable; 2, soft rubber layer flexibility is good, and toughness is strong after solidifying, and conditioned reaction is fast, and is isobaric effective; 3, can eliminate defectives such as the cutter of adobe is curved, concentric reducer, crackle, interlayer, eliminate because the inconsistent variety of issue that causes of cloth inequality or powder the assurance unfired brick quality.
