Abstract

The utility model relates to a hollow brick die, and belongs to the field of dies of brick machines. The hollow brick die comprises a pressure head, a die frame and an exhaust mechanism, wherein a die core is arranged in the die frame, a supporting plate is arranged below the die frame, and the exhaust mechanism is arranged in the die core; the exhaust mechanism comprises an exhaust hole, and a guide rod that can move up and down; the upper end of the guide rod is a first end in match with the exhaust hole, and the lower end of the guide rod is a second end in match with the supporting plate. According to the technical scheme, the hollow brick die has the advantages that the lower end surfaces of the die frame and the die core are ejected against the supporting plate, the second end of the guide rod is arranged against the supporting plate, and the first end of the guide rod upwards moves to block the exhaust hole during forming; the die frame and the die core upwards move during die releasing after the forming is done, the guide rod downwards moves at the same time, the second end of the guide rod moves away from the exhaust hole, thus outside air enters the inner wall of a hollow brick through the exhaust hole to ensure the consistency of pressure between the inner wall and the outer wall of the hollow brick, and as a result, bubbling and cracking are uneasy to be generated during die releasing of the hollow brick.

Description

A kind of hollow brick dies

Technical field

The utility model belongs to brick machine mould applications, is specifically related to a kind of hollow brick dies.

Background technology

Hollow brick light weight, intensity are high, insulation, sound insulation and noise reduction performance are good, and environmental protection, pollution-free, is the desirable packing material of frame structure building.Existing a kind of hollow brick dies comprises the framed and framed core rod being connected, pressure head and the gripper shoe that is arranged under framed forms.Region between the outer wall of core rod and framed inwall forms in order to place the die cavity of material, and core rod adopts hollow-core construction conventionally, and to avoid in knockout course, hollow brick inside and outside wall pressure difference is excessive, causes hollow brick produce bulge or occur crackle.When use, material is filled in die cavity, carries out moulding by drive ram sheeted product, then framed and core rod are upwards lifted to carry out the demoulding from gripper shoe, the hollow brick of moulding is stayed in gripper shoe, carries out subsequent treatment.

But there is such problem in this hollow brick dies in use: when in the time of the demoulding, framed and core rod lifts gradually from gripper shoe, because the outer wall of hollow brick directly contacts with air, its pressure being subject to is atmospheric pressure; And the inwall of hollow brick is not in the time that framed and core rod departs from gripper shoe completely, along with increase framed and core rod and gripper shoe distance, the pressure difference of hollow brick inside and outside wall increases gradually, for thinner hollow brick, is prone to bubbling or crackle.

Given this, this case inventor further investigate the problems referred to above, then has this case to produce.

Utility model content

The purpose of this utility model is to provide a kind of hollow brick dies that is not prone to bubbling and crack in the time of the demoulding.

In order to achieve the above object, the utility model adopts such technical scheme:

A kind of hollow brick dies, comprises pressure head, framed, is provided with core rod in framed, the die cavity that forms accommodating material between framed and core rod, also comprises the gripper shoe that is arranged on framed below, and one end of core rod is top board, the other end is openend, is hollow chamber between top board and openend; Also comprise and be arranged on the indoor exhaust gear of described hollow cavity, described exhaust gear comprises the guide rod that the steam vent that is arranged on described top board and length are mated with described core rod, the upper end of guide rod is the first end coordinating with steam vent, the lower end of guide rod is the second end coordinating with described gripper shoe, also comprise the guide plate that guides described guide rod to move up and down, it is indoor that guide plate is fixed on described hollow cavity.

In such scheme, described guide plate is two, is made as respectively guide plate and lower guide plate, and upper guide plate and lower guide plate are provided with the through hole passing for described guide rod, and the week of described guide rod, fixture block was arranged between guide plate and lower guide plate along being connected with fixture block.

In such scheme, through hole on described bottom guide is made as the first perforation, also comprise bolt, the screw rod of described bolt is screwed onto in the first perforation, the head of described bolt is arranged at the lower end of described bottom guide, also comprise the second perforation that runs through described bolt along described bolt length direction, described guide rod is bored a hole through described second and is extended to the lower end of described core rod.

In such scheme, between the head of described bolt and the lower surface of described bottom guide, be provided with spring washer.

In such scheme, described fixture block ring is located at edge of described guide rod week, and the lower surface of described fixture block is resisted against the upper surface of described screw rod, also comprises spring, and one end of spring is resisted against the upper surface of described fixture block, and the other end is resisted against the lower surface of described upper guide plate.

Also comprise the crossbeam that is erected at described framed upper surface, the two ends of crossbeam are welded on respectively described framed upper by connecting plate, and described core rod is fixed on the lower surface of crossbeam.

Adopt after the technical solution of the utility model, in the time of moulding, framed and lower surface core rod is supported in gripper shoe, and the second end of guide rod props up gripper shoe, the first end of guide rod moves up and blocks steam vent, and the hollow cavity of avoiding material to flow into core rod from steam vent is indoor.When moulding is complete while carrying out the demoulding, when framed and core rod moves up, guide rod moves down under the effect of self gravitation, the second end of guide rod departs from steam vent, outside air enters the inwall of hollow brick from steam vent, consistent to ensure the pressure of hollow brick inside and outside wall, hollow brick is not prone to bubbling and crack like this.
