The utility model discloses a mould matter is light, matched die face non-deformable, long service life, and the mould shell adopts rubber materials injection moulding, and size precision is high, and interchangeability is good, and the difficult concentration of stress is not afraid of the collision in the use.

Description

The cement railing mould

The utility model relates to the mould that a kind of placing concrete is used, especially a kind of mould that is used to produce cement railing.

The swinging cement railing is the construction material of house, garden, flower bed decoration, it is produced by mould, this cement railing mould structurally comprise two identical can be relatively and the formwork that closes, each formwork has a land area, two sidewalls and two end walls have a corresponding spill die cavity of 1/2nd profiles with cement railing and two groups of positioners that when two formwork matched moulds two die cavities are aligned with each other on the land area; On the upper end wall of formwork, there is a semicircular cast gate to be communicated with die cavity.Behind two formwork matched moulds, can will insert in the die cavity of mould by cast gate on reinforcing bar and the coagulation, solidify through the maintenance a few days, just can be with the cement railing demoulding that is shaped.The mould of this class cement railing, normally adopt the glass-reinforced plastic material home built, the formwork wall is thin, in use, the nonclient area that needs to form between outer surface, medial surface and the inner face of die cavity fills the reinforcing of sand filler, safeguarding the dimensionally stable of profile, land area, thereby mold weight is big, carrying and inconvenient operation; Because of the formwork moulding of fiberglass is by home built, dimensional accuracy is low, and interchangeability is poor, and formwork surface matter sclerine is thin, buckling deformation easily, and during matched moulds, the slit at matched moulds place is big, influences the quality of production and the concrete waste of railing product; This outer mold is easily aging, only 1 year service life.

At the problems referred to above, it is a kind of reasonable in design that the purpose of this utility model provides, the cement railing mould of light weight, long service life.

The utility model is to realize like this, the cement railing mould that is provided, it comprise two identical can be relatively and the formwork that lumps together, each formwork has a land area, two sidewalls, upper and lower end wall, the positioner that has a corresponding spill die cavity of 1/2nd profiles with cement railing and at least two groups that the die cavity of two relative formworks is aligned with each other on the described land area; A cast gate that is communicated with die cavity is arranged on the upper end wall of formwork, be fixed with respectively on described two inside surface of side wall a plurality ofly have at interval, transversely arranged reinforcement, between the back side of described land area and adjacent surface, two side or reinforcement, be fixed with several bosses respectively.

Described formwork adopts rubber-plastics material to make.

After adopting cement railing mould structure of the present utility model, owing on the side wall inner surfaces a plurality of transversely arranged reinforcements are arranged, and there are several bosses to be connected between the back side of land area and adjacent sidewall or the reinforcement, this reinforcement has increased the lateral stiffness of formwork side, and boss makes the leg-of-mutton robust structure of formation between land area and the sidewall, and land area shape is difficult for buckling deformation, and whole formwork rigidity improves, long service life, and can guarantee the quality of production of cement railing product; Because formwork adopts the rubber-plastics material injection molded, the dimensional accuracy height, production cost is low, and interchangeability is good, and is easy to use, and die quality significantly alleviates, and labor strength is low, and work efficiency is improved; The mould made of rubber-plastics material in addition, its case hardness is low than fiberglass, and good toughness is difficult for stress and concentrates in the use, be not afraid of collision, and resistance to ag(e)ing is good.

Concrete structure of the present utility model is provided by the following drawings.

Fig. 1 is the structure sectional side elevation of the utility model cement railing mould.

Fig. 2 is the side view of Fig. 1.

Fig. 3 is the front view of formwork among Fig. 1.

Fig. 4 be Fig. 3 along B-B to cutaway view.

Fig. 5 be Fig. 2 along A-A to cutaway view.

Below in conjunction with accompanying drawing embodiment of the present utility model is described in detail.

As Fig. 1, shown in Figure 2, the cement railing mould has two relative amalgamations of identical energy formwork 1,3 together, and the land area 5 of a flat shape is arranged on each formwork, vertical with land area two

sidewalls

8,9 and upper end wall 4, lower end wall 7.Formwork 1,3 adopts the rubber-plastics material injection moulding to make.

As Fig. 1, shown in Figure 3, a corresponding spill die cavity 6 of 1/2nd profiles with cement railing is arranged on the land area 5, the semicircular runners 2 that is communicated with die cavity is arranged on the upper surface of formwork 1,3.

By Fig. 3, Fig. 4 as can be known, on formwork 1 or 2 the land area two groups of positioners are arranged, every group of positioner comprises a truncated cone-shaped tappet 13 and and die cavity 6 center lines 12 symmetries on die cavity 6 sides, its shape, size and tappet 13 corresponding blind holes 14, when two formwork matched moulds, tappet on formwork and blind hole respectively with another formwork on blind hole and tappet match, thereby 6 of the die cavities of two formworks 1,3 can be aimed at mutually.

As Fig. 1, Fig. 2, shown in Figure 5, on

sidewall

8,9 inner surfaces of formwork 1 and 3, be fixed with many reinforcements 10 at interval, transversely arranged that have respectively, being illustrated as each side wall inner surfaces respectively has six reinforcements, and these reinforcements have increased the lateral stiffness of sidewall.The back side and adjacent two side 8 at formwork 1 or 3 land areas 5, having several to have triangle between the reinforcement 10 on 9 inner surfaces has the boss 11 and the back side of land area 5 to be solidly fixed, make between the back side of land area and the reinforcement on the two side to have constituted leg-of-mutton rock-steady structure, the flatness of land area is stablized.

Certainly above-mentioned boss also can be connected between the back side and side wall inner surfaces of land area.

Cement railing mould of the present utility model is reasonable in design, and light weight, long service life are inexpensive, can produce the cement railing that standard is unified, quality is high, inexpensive with it.
