Background

Along with the continuous development of the building field technology, more and more high buildings adopt the exhaust flue and the exhaust passage of prefabricated structure, and the prefabricated exhaust passage not only can improve holistic construction progress, moreover the material resources of using manpower sparingly. However, the existing discharge flue is of a rectangular hollow structure, is integrally formed by adopting a mould machine and is of a concrete structure, but in order to save the material of the flue, the wall thickness of the discharge flue is thinner and thinner, and when two vertical discharge flues are arranged in a row, dislocation is easily caused, so that the concrete flows into the discharge flue, or the discharge flue is not tightly blocked, and the like, so that the construction progress is influenced, the construction quality cannot be ensured, the sealing performance and the air leakage rate cannot reach the use function, the design requirements cannot be met, and the hidden construction trouble is easily left in the internal corner part.

Disclosure of Invention

The to-be-solved technical problem of the utility model is to provide an automatic pressure regulating water conservancy diversion discharge flue mechanism mould head, this mould head can directly process out the water conservancy diversion discharge flue that has boss structure to the discharge flue that makes the installation is pegged graft the assembly in proper order, guarantees the cooperation precision, and each item indicates that the standard can reach the designing requirement.

For solving the above problems, the specific technical scheme of the utility model is as follows: a machine-made mould head of an automatic pressure-regulating diversion discharge flue comprises a male mould and a female mould; the male die is of a hollow trapezoidal platform structure with a large opening area at one end and a small opening area at the other end, and the end with the large opening area is movably connected with the male die of the existing discharge flue die; the female die is of a rectangular frame structure, the inner edge of the rectangular frame is matched with the end part with small opening area of the male die, and the outer edge of the rectangular frame is connected with the female die of the existing discharge flue die.

The male die is composed of four single plates, the four single plates serve as four side surfaces of the trapezoidal table respectively, the outer surface of each single plate is in an isosceles trapezoid shape, two side edges of each trapezoid are provided with inward inclined bends, and when the axis of the male die is horizontally arranged, the inclined bends of the single plates on the upper side and the lower side are overlapped on the inclined bends of the single plates on the left side and the right side of the corresponding position.

The inner frame of the female die of the rectangular frame body is provided with a die drawing inclined plane, the inclination angle of the die drawing inclined plane is 2-10 degrees, a clamping plate which is flush with the outer surface of the female die is arranged at a small opening of the die drawing inclined plane, and the shape of the inner edge of the clamping plate is consistent with that of a small port of a male die.

The appearance of the drawing die inclined plane is consistent with that of the clamping plate, and the drawing die inclined plane is equidistantly moved outwards by 10-30 mm.

And one end of the male die with large opening area is provided with an insertion plate which is movably connected with the existing machine-made die.

This automatic pressure regulating water conservancy diversion discharge flue mechanism mould head is used for current discharge flue mould front end, makes the discharge flue of original straight mouthful become the socket structure discharge flue that has interior inclined plane, has not only guaranteed that the discharge flue of two adjacent installations can peg graft, improves the installation effectiveness, and the internal surface of discharge flue socket has the inclined plane of adduction moreover, plays the mesh that the throat pressure boost was transferred and is flowed.

Detailed Description

As shown in fig. 1 to 4, a mold head for an automatic pressure-regulating flow-guiding discharge flue mechanism comprises a male mold 1 and a female mold 2; the male die 1 is a hollow trapezoidal platform structure with a large opening area at one end and a small opening area at the other end, the end with the large opening area is movably connected with the male die of the existing discharge flue die, in the embodiment, the end with the large opening area of the male die is provided with the plugboard 1-3, the plugboard 1-3 is movably plugged with the existing machine-made die, and other movable connection modes can also be adopted; the female die 2 is of a rectangular frame structure, the inner edge of the rectangular frame is matched with the end part of the male die with small opening area, and the outer edge of the female die 2 is inserted into the female die of the existing die. The male die 1 adopts a trapezoidal platform structure, so that after the discharge flue is formed, the inner surface is of a closing structure, the cross-sectional area is reduced, and the gas flow rate is improved.

The male die 1 is composed of four single plates 1-1, the four single plates are respectively used as four side surfaces of the trapezoidal table, the outer surface of each single plate 1-1 is in an isosceles trapezoid shape, two side edges of the isosceles trapezoid shape are provided with inward inclined bends, and when the axis of the male die is horizontally arranged, the inclined bends of the single plates on the upper side and the lower side are overlapped on the inclined bends of the single plates on the left side and the right side of the corresponding positions. The male die 1 is composed of four single plates 1-1, and is respectively assembled with the existing die, in the demolding process, the single plates 1-1 on two sides move inwards, the inclined bending 1-2 of the upper single plate 1-1 and the lower single plate 1-1 lose supporting force, and the upper single plate 1-1 and the lower single plate 1-1 contract inwards, so that smooth demolding can be realized.

As shown in figure 5, the inner frame of the female die 2 of the rectangular frame body is provided with a drawing inclined plane 2-1, the inclination angle of the drawing inclined plane 2-1 is 2-10 degrees, a clamping plate 2-2 which is flush with the outer surface of the female die is arranged at the small opening of the drawing inclined plane, and the shape of the inner edge of the clamping plate is consistent with that of the small port of the male die. The appearance of the drawing die inclined plane is consistent with that of the clamping plate, and the equidistant outward movement H is 10-30 mm. The female die 2 adopts a structure that the die drawing inclined plane 2-1 is combined with the clamping plate 2-2, so that the discharged flue after demoulding has a socket structure, and the two flues can be conveniently spliced with each other.
