Abstract
The utility model discloses a lower mold core for perforated brick mold, whose ash discharge holes have different cross sections. The utility model is characterized in that the ash discharge holes are changed from equal-diameter straight holes into cone-shaped through holes, and the engagement gap of equal-diameter straight holes are smaller than that of cone-shaped through holes under former equal engagement height. The utility model is advantageous in that the engagement height of equal-diameter through holes can be reduced by adopting cone-shaped variable cross-section, no big-area feed leakage is ensured and friction is reduced; ash discharge is facilitated and mold jamming is prevented if small amount of material is leaked.
Description
Technical field
The utility model relates to the lower mold core of a kind of porous brick die, particularly a kind of porous brick die.
Background technology
The lower mold core of existing porous brick die; ash-hole in its core rod is to be changed to a kind of isometrical column through hole; the ash discharge through hole of this isometrical column; under the equal height condition; fit clearance between core bar and the core rod hole is little, stops up easily when ash discharge, simultaneously because isometrical height is big, and snap gauge takes place during the big so mould operation of the frictional force of being brought easily; usually needing to cause shutting down mediation, promptly having influenced production efficiency, also increased working strength of workers.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art part, and a kind of easy ash discharge is provided, can guarantee mould operation smoothly, be difficult for the lower mold core of the porous brick die of snap gauge.
A kind of lower mold core of porous brick die, its structural feature is: the ash-hole of described lower mold core is the hole that cross section changes.
The ash exhauster that adopts this cross section to change is difficult for stopping up when ash discharge, and frictional force is little, and the mould operation is smooth and easy, is difficult for taking place snap gauge.
The ash-hole that described cross section changes is a kind of round taper hole, and the big end of round taper hole down.
The ash-hole that described cross section changes or for a kind of bus be the hole of curve.
The hole that described cross section changes can also be by superposed isometrical cylinder hole and be positioned at the hole that the cross section of bottom changes and constitute.
Because core bar is in running, can make to be positioned at ash-hole core rod generation wearing and tearing on every side, therefore ash-hole top be adopted isometrical column through hole formation, just can improve the wearability of core rod, thereby when guaranteeing core rod intensity, can guarantee that again ash exhauster has good ash discharge effect.
The hole that the cross section of described bottom changes is a kind of round taper hole.
The utility model also is
The outer peripheral face of lower mold core is for to have certain gradient structure with respect to the lower mold core axial line.
The outer peripheral face of lower mold core is arranged to have certain gradient structure with respect to the axial line of lower mold core, when lower mold core is moved, can reduces the frictional force between core rod and the die cavity like this.
In sum, advantage of the present utility model is:
The ash-hole that the utility model will have now in the lower mold core makes conical through-hole into by isometrical straight hole, isometrical column through hole is compared with conical through-hole, under former identical engagement height, the fit clearance of isometrical column through hole is little, use the taper variable cross-section instead, thereby can reduce isometrical column engagement height, both guarantee that large tracts of land was not leaked material, reduce friction again.Leak material if any trace simultaneously, also help ash discharge, prevent snap gauge.The utility model is also made the outer peripheral face of lower mold core with respect to its axial line and is had certain gradient structure simultaneously, when lower mold core is moved, can reduce the frictional force between core rod and the die cavity like this.

The specific embodiment
Below in conjunction with embodiment the utility model is described in more detail.
Embodiment 1
A kind of lower mold core of the porous brick die shown in Fig. 1-4, the hole that the ash-hole 1 of described lower mold core changes for cross section, the hole that described cross section changes is made of the difform hole of upper and lower two parts, superposed hole be shaped as isometrical cylinder hole 11, be positioned at the bottom the hole be shaped as hole 12 with certain taper.The outer peripheral face 2 of lower mold core is for to have certain gradient structure with respect to the lower mold core axial line.
It is same as the prior art that present embodiment is not stated part.
