Abstract
The utility model relates to the impeller and making mould of a centrifugal water pump, in particular to a single suction impeller made from thermosetting plastics. The single suction impeller made from thermosetting plastics is adopted with the glass-reinforced plastic material and shaped via being pressed for one time with a purpose-made mould. The mould is composed of a front mould surface and a back mould surface which are respectively provided with mould cores of the front shroud and the back shroud of an impeller, a plurality of pairs of cores and middle shaft cores of an upper lamina and a lower lamina equipped between the front mould surface and the back mould surface, an upper locating piece and a lower locating piece for fixing the cores of the upper lamina and the lower lamina, an outer tightening hoop and an inner hoop between the upper locating piece and the lower locating piece. The whole impeller made by the impeller and making mould of a centrifugal water pump has simple art, time saving and labor saving, and the whole impeller is made with small resistance, high efficiency, corrosion prevention and eternal combined lamina.
Description
The utility model relates to a kind of impeller and mfg. moulding die of centrifugal water pump, the single-suction (single-in let) impeller that particularly adopts thermosetting plastics to make.
Used thermosetting plastics impeller on the existing water pump as the fiberglass impeller, all is after blade, front shroud, back shroud are made respectively, is shaped with screw assembling or bonding.Such processing technology complexity, time-consuming, effort, the impeller resistance of producing is big, and efficient is poor, and the corrosion of normal coping screw or adhesive are aging and come off, and causes blade to separate, and causes water pump normally not move.
The purpose of this utility model is to provide a kind of manufacturing process simple, and resistance is little, overall thermal solidity plastic impeller and mfg. moulding die thereof that efficient is high.
Overall thermal solidity plastic impeller adopts special mould, disposable drawing.
Below in conjunction with embodiment shown in the drawings the utility model is explained in detail.
Fig. 1 is whole fiberglass impeller schematic diagram, and Fig. 2 is whole fiberglass impeller mold A-A cutaway view, and Fig. 3 is the B-B cutaway view of Fig. 1; Among the figure: 1, blade, 2, back shroud, 3, shaft hole, 4, front shroud, 5, outer lock ring, 6, go up locating piece, 7, lower blade fuse, 8, the blade fuse, 9, impeller, 10, preceding die face, 11, spring, 12, the axle fuse, 13, back die face, 14, following locating piece, 15, interior lock ring, 16, screw, 17, nut.
Overall thermal solidity plastic impeller comprises: blade (1), back shroud (2), front shroud (4); Have garden shape water inlet in the middle of the shaft hole (3) that has convex on the back shroud (2), front shroud (4).This impeller adopts glass-reinforced plastic material with the disposable drawing of special mould, and need not they be connected into integral body with screw or screw thread, thereby has blade and be evenly distributed, and resistance is little, efficient height, advantages such as blade never becoming loose.
The mould of making overall thermal solidity plastic impeller comprises: the preceding die face (10) and the back die face (13) that have impeller (9) front shroud (4) and back shroud (2) the mould heart respectively, be contained in several between two die faces (10,13) to blade fuse (8) and lower blade fuse (7), be contained in the middle axle fuse (12) of two die faces (10,13), play the last locating piece (6) and the following locating piece (14) of the effect of fixing upper and lower lobes sheet fuse (7,8), lock ring (5) and lock ring (15) in several outside between locating piece (6,14), having.
Upper and lower locating piece (6,14) and outer lock ring (5) are made the garden annular, have several corresponding screws on it, are used for fixing blade fuse (7,8); Locating piece (6,14) and the contacted side of blade fuse (7,8) have groove and the flange that male and female are harmonious up and down, are used for distribution, fixed blade fuse (7,8).
Preceding die face (10) and back die face (13) are convex, and its landolsring matches with upper and lower locating piece (6,14).
On axle fuse (12) side relative, have groove, spring (11) is housed in the groove with preceding die face (10).
During making, blade fuse (7,8) is arranged between the garden upper and lower locating piece of annular (6,14), fix its position with inside and outside lock ring (15,5) and screw (16) nut (17) in the space, put into then on the back die face (13), the axle fuse (12) that will have spring (11) places blade fuse (7,8) and die face (13) center, back, add glass-reinforced plastic material again, topped on it with preceding die face (4), heating, punching press.By anti-order dismounting, promptly get the integral wheel of once-forming at last.
Obviously, use described Mold Making integral wheel, save time, laborsaving, technology is simple, and the integral wheel of making to have a resistance little, the efficient height, corrosion-resistant, the advantage such as blade is never to be separated.
Claims (3)
1, the overall thermal solidity plastic impeller of using on a kind of water pump is characterized in that: form this impeller by blade (1), back shroud (2), front shroud (4).
2, make the described impeller mold of claim 1, it is characterized in that: it comprises preceding die face (10) and the back die face (13) that has impeller (9) front shroud (4) and bonnet (2) the mould heart respectively, be contained in the several axle fuses (12) between two die faces (10,13) to upper and lower blade fuse (8,7) and centre, the last locating piece (6) and the following locating piece (14) of fixing upper and lower blade fuse (7,8), lock ring (5) and interior lock ring (15) outside between two locating pieces (6,14), having.
3, impeller mold according to claim 2 is characterized in that: have groove on the side of described axle fuse (12) and the relative end of preceding die face (10), spring (11) is housed in the groove.
