This mould is pour to cylindrical test piece can make things convenient for, swift the cylindrical test piece that needs have the joint crack. The utility model discloses a following technical scheme realizes.
A cylindrical test piece pouring mold with parallel cracks comprises a mold main body 1, a bolt 2, a movable rotating shaft 3, a joint crack prefabricated sheet 4, a fixing strip 5 and a clamping groove 6; the cylindrical test piece pouring mold is formed by combining symmetrical structures, each symmetrical structure comprises a mold main body 1 formed by two detachable large-radius semi-cylinders, a clamping groove 6 and a movable rotating shaft 3, the mold main body is formed by two detachable small-radius semi-cylinders, the clamping groove 6 and the movable rotating shaft 3 are formed by two groove strips, the middle positions of the two detached large-radius semi-cylinders are respectively connected with the two detached small-radius semi-cylinders, the two detached small-radius semi-cylinders are connected through the movable rotating shaft 3, and the end parts of the side ends of the two detached large-radius semi-cylinders are respectively provided with one groove strip; when the device is used, symmetrical structures are combined through the movable rotating shaft 3 to form a cylindrical mold main body 1 and a clamping groove 6, a joint crack prefabricated sheet 4 is installed between the mold main body 1 at the middle upper part and the mold main body 1 at the lower part of the combined cylindrical test piece pouring mold, the joint crack prefabricated sheet 4 is a round metal solid surface, a bolt ring is arranged at the end part of the joint crack prefabricated sheet 4, the diameter of the bolt ring is the same as that of a synthesized small-radius cylinder, a bolt 2 penetrates through the small-radius cylinder and the bolt ring of the combined cylindrical test piece pouring mold, and a fixing strip 5 matched with the clamping groove 6 penetrates through the clamping groove 6.
The die main body 1 and the joint crack prefabricated pieces 4 are made of steel.
The working principle of the cylindrical test piece pouring mold with the parallel cracks is as follows:
as shown in fig. 1, the symmetrical structures of the cylindrical test piece pouring molds of each parallel crack are combined, the cylindrical test piece pouring mold of each parallel crack is inserted into a clamping groove 6 to form a fixing strip 5 matched with the clamping groove 6, the cylindrical test piece pouring molds of two parallel cracks are combined and provided with a joint crack prefabricated sheet 4 in the middle, and a bolt 2 is inserted into a small-radius cylinder and a bolt ring of the combined cylindrical test piece pouring mold in a penetrating manner; pouring a test piece material to a cylindrical test piece pouring mold at the top, waiting for the pouring of the test piece material to be half-dry, overturning the cylindrical test piece pouring mold of the combined parallel crack, continuously pouring the test piece material to the top of the cylindrical test piece pouring mold of the overturned parallel crack, waiting for the pouring of the test piece material to be half-dry, rotating the pin ring at the end part of the joint crack prefabricated sheet 4, rotating the joint crack prefabricated sheet 4 out, compacting the half-dry pouring test piece material at the top downwards to generate 180-degree parallel joint cracks, when the model is completely solidified, drawing out the fixing strip 5 from the clamping groove 6 and the pin 2, unfolding a symmetrical structure, and taking the model out of the cylindrical test piece pouring mold.
The utility model has the advantages that:
the cylindrical test piece pouring mold has good flexibility and can be assembled and used according to different requirements; the material of the die is steel, so that the die can be repeatedly used for many times, the material is saved, and the manufactured test pieces are kept consistent; the test piece does not need to be cut and bonded with resin in the manufacturing process, so that the test error is reduced; when the die is poured, 180-degree parallel joint cracks can be generated only by rotating the joint crack prefabricated pieces of the die; when the test piece is manufactured, the fixing strip is only required to be detached, the mold is opened for 180 degrees through the movable rotating shaft, and the mold is removed.
