Description

Vertical pouring hydraulic opening and closing mould for box culvert of character-shaped piece Technical Field The application relates to the field of box culvert molds, in particular to a vertical pouring hydraulic opening and closing box culvert mold for a character-shaped piece. Background The box culvert is a precast concrete structural member commonly used in the fields of water conservancy, traffic, municipal administration and the like, has various cross-sectional shapes, and is widely applied due to the fact that the 'mesh' -shaped box culvert is internally provided with a plurality of parallel culverts, and has high structural strength and good water passing capability. At present, vertical pouring dies are adopted for molding in the production of the 'mu' -shaped box culvert. In the prior art, the vertical box culvert mould mainly comprises an outer mould and an inner mould, wherein the outer mould and the inner mould are of integral structures. During demoulding, the whole internal mould is pulled out of the formed concrete box culvert through a hydraulic system. However, for the complex structure of the 'mu' shape with multiple long and narrow inner cavities, However, the contact area of the integral internal mold and the concrete is large, the mold drawing resistance is large, the demolding is difficult, the pull damage on the surface of the concrete and even the damage of components are easy to cause, and the mold drawing gradient of the integral internal mold is usually smaller due to the structural limitation, so that the demolding difficulty is further increased, and the improvement is needed. Disclosure of Invention In order to solve the problems of difficult demolding and low efficiency of the existing box culvert mold, the application provides a vertical pouring hydraulic opening and closing box culvert mold for a character-shaped piece. The application provides a vertical pouring hydraulic opening and closing mould for a box culvert of a character part, which adopts the following technical scheme: The utility model provides a mesh word box culvert mould that hydraulic pressure opened and shut is pour to vertical, includes the bottom plate and locates preceding external mold, well culvert centre form, two back external molds and two side culvert centre forms on the bottom plate, well culvert centre form is located the middle part of bottom plate, two back external mold uses the axis of bottom plate to lay as axisymmetrically, two back external mold is connected with the both ends of preceding external mold respectively, well culvert back external mold is kept away from the one end of preceding external mold and is connected with well culvert centre form, preceding external mold and two back external molds enclose and form the frame, two side culvert centre form is located the frame, well culvert centre form is located between two side culvert centre forms, preceding external mold and back external mold are all in through moving assembly sliding connection on the bottom plate for moving assembly is used for driving preceding external mold and back external mold are close to each other or keep away from, preceding external mold and back external mold are connected through coupling assembling. By adopting the technical scheme, the die is divided into a plurality of independent functional modules such as the front outer die, the rear outer die, the middle culvert inner die, the side culvert inner die and the like, so that the precise disassembly of the complex 'mu' -shaped structure is realized. The culvert inner mold is positioned in the middle of the bottom plate and used for forming a middle culvert, the two side culvert inner molds are positioned at two sides and used for forming culverts at two sides, and the front outer mold and the rear outer mold are jointly enclosed to form an integral outer contour. Through moving the subassembly, preceding external mold and back external mold can be close or keep away from each other along the bottom plate to close in order to form inclosed pouring space when pouring, open in order to give up the space when the drawing of patterns, the product of being convenient for hangs out. The modularized and movable design ensures that the actions of all the parts are independent and do not interfere with each other, and effectively solves the problem of demolding interference caused by rigid connection of the traditional mold. The connecting assembly ensures the connection strength of the front outer die and the rear outer die in the die assembly state, ensures the integral rigidity of the die and improves the casting molding precision. Optionally, the front outer die comprises a top plate outer die and two corner dies, the two corner dies are positioned at two sides of the top plate outer die, and the corner dies are rotationally connected to the top plate outer die through a rotating shaft; the middle culvert internal mold comprises a middle culvert front
