Abstract
The utility model discloses a hollow cubic prefabricated mould last, which consists of supporting plates, angular elastic steel plates and a forward and backward thread screw, wherein each supporting plate is provided with a central hole, and leaves are arranged on the four sides of the supporting plate; four angular elastic steel plates are movably connected through hinges to form a hollow mould last; the supporting plates are positioned in the hollow mould last; the angular elastic steel plates are supported by the leaves on the supporting plates; the forward and backward thread screw penetrates through the central hole of the supporting plates and is combined with the leaves on the four sides of the supporting plate through threads; and the two ends of the forward and backward thread screw are provided with torsion rings. According to the hollow cubic prefabricated mould last, shrinkage of the hollow mould last can be achieved by adjusting the leaves on the supporting plates; after pouring, the mould last can be easily drawn out by loosening the supporting plates after a member is solidified, so that mechanical drawing is not required and the equipment purchasing expenditure is saved; and according to building requirements, mould lasts of different shapes can be manufactured, or the hollow size is increased, i.e., the material is saved and the cost of the member is also saved. The hollow cubic prefabricated mould last has the advantages of simple structure, easiness and convenience for manufacturing, low manufacturing cost, material saving, time saving and reduced cost during use, suitability for building industry and broad market prospect.
Description
Technical field
The utility model relates to the building prefabricated components field, relates in particular to a kind of hollow cubic body prefabricated molds shoe last or hat block.
Background technology
At present, in building industry prefabricated components industry, when the precast hollow member, most of steel pipe, plastic tube filling hollow parts of adopting done core rod; Treat to extract out with mechanical territory hoist engine before member solidifies, the problem that this kind method exists is that equipment purchasing is many, and cast is worried about many; Once forget rotation mould shoe last or hat block, treat that member solidifies back core pipe fully and is difficult to extract out, scrap is many; Core body can only be a cylinder in addition, can't the rotating of other shape, so core body is confined to cylinder.
Summary of the invention
In view of above-mentioned, the purpose of the utility model is to provide a kind of hollow cubic body prefabricated molds shoe last or hat block.
The utility model is realized through following technical scheme:
A kind of hollow cubic body prefabricated molds shoe last or hat block is made up of gripper shoe, knuckle spring steel plate and positive and negative silk screw rod, and gripper shoe is provided with centre bore, and its four limit is provided with pattra leaves; 4 knuckle spring steel plates flexibly connect through hinge, constitute hollow mould shoe last or hat block; Gripper shoe is arranged in hollow mould shoe last or hat block, and the pattra leaves on the gripper shoe is supported the knuckle spring steel plate; Positive backward leading screw passes the centre bore of gripper shoe, and the pattra leaves through screw thread and gripper shoe four limits chews and closes; Positive backward leading screw two ends are provided with torsion ring;
Above-mentioned gripper shoe has 4～10.
Advantage of the utility model and beneficial effect:
1, the utility model can reach the contraction of hollow mould shoe last or hat block through the pattra leaves on the adjustable support plate, after the cast, treats that member solidifies the loosening gripper shoe in back and can easily extract the mould shoe last or hat block out; Need not mechanical pull; Saving equipment purchasing expenditure, and can build needs as required, make difform mould shoe last or hat block; Or the increase hollow volume, promptly material-saving is practiced thrift the member cost again.
2, the utility model is simple in structure, makes to put just, and is honest and clean at the bottom of the cost, uses its material-saving, saves time, falls cost, is applicable to building industry, and market prospects are wide.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the sketch map of gripper shoe among Fig. 1.
Among the figure: the positive backward leading screw 5-of 1-gripper shoe 2-knuckle spring steel plate 3-hinge 4-torsion ring 6-centre bore 7-pattra leaves
The specific embodiment
Below in conjunction with description of drawings the utility model is done further explanation:
As shown in Figure 1, a kind of hollow cubic body prefabricated molds shoe last or hat block is made up of gripper shoe 1, knuckle spring steel plate 2 and positive backward leading screw 4, and gripper shoe 1 is provided with centre bore 6, and its four limit is provided with pattra leaves 7; 4 knuckle spring steel plates 2 flexibly connect through hinge 3, constitute hollow mould shoe last or hat block; Gripper shoe 1 is arranged in hollow mould shoe last or hat block, and the pattra leaves 7 on the gripper shoe 1 is supported knuckle spring steel plate 2; Positive backward leading screw 4 passes gripper shoe 1 centre bore 6, and the pattra leaves 7 through screw thread and gripper shoe 1 four limits chews and closes; Positive backward leading screw 4 two ends are provided with torsion ring 5;
Described gripper shoe 1 has 4～10.
Embodiment
Positive backward leading screw 4 is passed the centre bore 6 of gripper shoe 1, and rotation torsion ring 5 is through pattra leaves 7 angles on the threaded adjustment gripper shoe 1 on the positive backward leading screw 4; When the angle of pattra leaves 7 during perpendicular to knuckle spring steel plate 2, hollow mould shoe last or hat block becomes maximum cube, is used for molding; After pouring into a mould successfully, when needing to take out the mould shoe last or hat block, through rotation torsion ring 5; Adjustment pattra leaves 7 angles, the angle of pattra leaves 7 and knuckle spring steel plate 2 are during less than 90 °, and the hinge 3 of knuckle spring steel plate 2 junctions is loosening; Hollow mould shoe last or hat block dwindles, and breaks away from pour mass, extracts the mould shoe last or hat block out.
