Abstract
The utility model provides a compacting tool set for an impeller of a glass fibre reinforced plastic centrifugal pump, which is an integral compacting tool set for an impeller of a glass fibre reinforced plastic centrifugal pump. The utility model is characterized in that every core mould of a flow channel of the compacting tool set is composed of a core mould I, a core mould II, a core mould III and a core mould IV (12, 13, 14, 15), wherein, the core moulds I, II (12, 13) of the flow channel are outwards disengaged, and the core mould I (12) of a flow channel in the core moulds I, II (12, 13) of the flow channel has inclination with a thick outer part and a thin inner part; the core moulds I, II (12, 13) of the flow channel are fixed on an upper outer mould (9) by screw nails (21) when assembled; the core moulds III, IV (14, 15) of the flow channel are inwards disengaged are fixed on a core mould of a wheel centre (17) through a tongue-and-groove structure. The utility model can integrally compact and manufacture the impeller of a glass fibre reinforced plastic centrifugal pump. Compared with the quality of item of a glass fibre reinforced plastic impeller which is compacted and glued, the quality of item of the utility model has the advantages of good integrity and high strength. The utility model is mainly characterized in that the core moulds of the flow channel are formed by combining a plurality of core moulds of the flow channel, and the core moulds of the flow channel can be disengaged from an impeller product according to a definite sequence.
Description
The utility model relates to the whole compacting tool set of a kind of glass fibre reinforced plastics impeller, particularly a kind of whole compacting tool set of glass fibre reinforced plastics centrifugal pump impeller.
Glass fibre reinforced plastics also claims glass fiber reinforced plastic, is a kind of good resistant material, adopts already in the manufacturing of centrifugal pump impeller.But existing glass fibre reinforced plastics centrifugal pump impeller is to be divided into two compression mouldings, is bonded with tackiness agent again.The impeller integrity that this method is made is poor, and binding face is its weakness, is easy in the running throw off damage.
The purpose of this utility model provides the whole compacting tool set of a kind of glass fibre reinforced plastics centrifugal pump impeller, and it can realize the integral body compacting manufacturing of glass fibre reinforced plastics centrifugal pump impeller.
The purpose of this utility model is achieved in that the impeller channel stamen mould by adopting polylith to combine, when the glass fibre reinforced plastics impeller on mould after the compression moulding, it can be deviate from from impeller channel in certain sequence, solved the difficult problem of runner stamen moulding/demoulding, thereby realize the integral body compacting of glass fibre reinforced plastics impeller, specifically, a kind of mould of whole pressed glass steel centrifugal pump impeller, it is characterized in that: each runner stamen mould of this mould is by four stamen mould I, II, III, IV (12,13,14,15) combine.Wherein said runner stamen mould I of outwards deviating from, the runner stamen mould I (12) in the II (12,13) have outer thick interior thin gradient; Be fixed on the external mold (9) with screw (21) when runner stamen mould I, II (12,13) assembling; Described runner stamen mould III of inwardly deviating from, IV (14,15) are fixed on the core wheel stamen mould (17) by tenon groove structure.
The concrete structure of model utility is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is the structural type figure according to the glass fibre reinforced plastics impeller of whole compacting of wanting that the utility model proposes.Wherein (a) is main sectional view, (b) is the sectional view of bowing.
Fig. 2 is the die cut view that is used for whole pressed glass steel impeller provided by the utility model.
Each part name is in Fig. 2: (1) drop handle; (2) base plate; (3) set screw; (4) locating stud; (5) external mold under; (6) drag hook; (7) screw; (8) runner stamen mould locating stud; (9) go up external mold; (10) top die; (11) dip mold; (12) runner stamen mould I (13) runner stamen mould II; (14) runner stamen mould III; (15) runner stamen mould IV (16) set screw; (17) core wheel stamen mould; (18) stamen; (19) keyway stamen mould; (20) set screw; (21) runner stamen mould set screw; (22) filling block (not expressing among the figure); (23) filling block set screw (not expressing among the figure); (24) external mold cylinder locating stud up and down.
Below in conjunction with details and the working condition of accompanying drawing detailed description according to the concrete mould that the utility model proposes.
With reference to Fig. 2, the major character of this mould is that the stamen mould of each runner is formed (i.e. stamen mould among the figure 12,13,14,15) by four, has outer thick interior thin gradient in order to deviate from, must make the stamen mould of deviating from first 12 from the runner of glass fibre reinforced plastics impeller.The demoulding of runner stamen mould is followed successively by I, II, III, IV (being stamen mould 12,13,14,15) in proper order.Wherein, I, II are outwards deviate from, and III, IV are inwardly deviate from.
With reference to Fig. 2, this mould structure is made the following instructions: the first, stamen (18) wheel stamen stamen mould (17) keyway stamen mould (19) is fixing by screw (16,20), is combined as the stamen mould assembly.Last external mold (9) filling block (22) is fixing by screw (23), is combined as external mold.The part combination is the processing for the ease of mould.The second, runner stamen mould III, IV (14,15) adopt tenon groove structure with the mount of core wheel stamen mould.Go up the processing tenon at runner stamen mould (14,15), go up processing groove at wheel stamen stamen mould (17).Three, the mount of runner stamen mould I, II (12,13) is by pin (8) location, is fixed on the external mold (9) with screw (21).Four, up and down both sides are inserted molding compound and are suppressed, to improve glass fibre reinforced plastics impeller Products Quality.
With reference to Fig. 2, the whole compacting of glass fibre reinforced plastics impeller main operational steps is as follows:
(1) will descend external mold (5), stamen mould assembly (18,17,19), dip mold (11) to fix with screw (3) by pin (4) location with base plate (2).And with in runner stamen mould III, IV (14,15) insertion wheel stamen stamen mould (17) mould.
(2) molding compound of adding Lower Half institute requirement amount in lower mold cavity.
(3) runner stamen mould I, II (12,13) are located by pin (8), be fixed on the external mold (9) with screw (21).
(4) will go up external mold and be inserted in down on the external mold, and it is fixing with drag hook (6) to tighten screw (7) by the location.
(5) in upper cavity, add institute's requirement amount molding compound.
(6) top die (10) is inserted in.
(7) compacting.
(8) demoulding.Unclamp screw (7) and throw off drag hook (6).From top, top stamen mould (18), together with base plate, following external mold, dip mold (2,5,11) are deviate from together.Screw out screw (21), top top die (10) deviates to go up external mold (9).Throw off top die (10).Take out runner stamen mould I, II, III, IV (12,13,14,15) successively, promptly get whole pressed glass steel impeller goods shown in Figure 1.
