Description
Technical field
The present invention relates to sports goods manufacture technology field, the manufacture method of the thick embryo of club that especially a kind of inner wall thickness is inconsistent.
Background technology
The inner wall thickness ratio of the thick embryo of existing club is more uniform, the consistency of thickness of its weight bearing area and non-weight bearing area, thus causing that the weight of hockey lever is big, and underaction during use, relatively heavy, have impact on serviceability.
Summary of the invention
The manufacture method of the thick embryo of club that the invention aims to solve the deficiency of above-mentioned technology and provide a kind of inner wall thickness inconsistent, it gets final product, by one-shot forming, the thick embryo of club that inner wall thickness is uneven.
In order to achieve the above object, the manufacture method of the thick embryo of club that inner wall thickness designed by the present invention is inconsistent, it comprises the steps:
(1), the signature bar mould inner surface being used for the silica gel signature bar molding that crest line thickens is cleaned up, and brush upper mould release；
(2), on the outer peripheral face of steel core bar, brush silica gel solid, then steel core bar is baked to surface white till；
(3), by the bar shaped silica gel piece parcel steel core bar being made up of raw silica gel material；
(4), the steel core bar being enclosed with bar shaped silica gel piece putting in signature bar mould, close signature bar mould, and is heated molding, and forming temperature 160-200 DEG C, molding time is 50-70min；
(5) silica gel that the crest line being made up of bar shaped silica gel piece and steel core bar molding is thickened after completing by molding is given as security bar and is taken out；
(6), by carbon fiber or glass fibre adhere to liquid-state viscosity resin, and by each bar fibers parallel and evenly distributed, form cloth-like silvalin material；
(7), cloth-like silvalin material is cut into sheet-like fiber yarn material；
(8) the plastics membrane tube putting one end sealing outside bar given as security by the silica gel, by crest line thickened, and the opening of plastics membrane tube inserts vacuum tube, plastics membrane tube and silica gel is given as security the air between bar and extracts out, makes plastics membrane tube be close to silica gel and gives as security bar；
(9), at the silica gel being enclosed with plastics membrane tube give as security and bar wraps up some layers be attached with the sheet-like fiber yarn material of tackifying resin, obtain the thick embryo preform of club；
(10) the thick embryo forming mould of club, by thick for club embryo preform is put into, at temperature 120-150 DEG C of compacted under 50-80min；
(11), thick for the club of forming embryo preform is taken out from mould, silica gel is given as security bar and takes out from the thick embryo preform of club, the inner wall thickness thick embryo of inconsistent club can be obtained.
(8) in repeat the above steps-(11), the repeatable thick embryo of production club.
As optimization, described steel core bar outer peripheral face is provided with spiral projection, and described protruding cross section is isosceles triangle, and the dual-side in the cross section of projection is identical.
The spacing between projection adjacent on same axial location is 0.1-0.15cm, and protruding height is 0.1-0.2cm.
One end of steel core bar is provided with nut.
The described longitudinal cross-section giving as security bar mould is: be provided with the octagonal structure that the square concave inward structure of four consistent size is formed on four angles of rectangular configuration.
When the signature bar mould inner surface being used for the silica gel signature bar molding that crest line thickens is cleaned, first the heating of signature bar mould is carried out after 62-85 DEG C again.
The manufacture method of the thick embryo of club that the obtained inner wall thickness of the present invention is inconsistent, to give birth to bar shaped silica gel piece that silica gel material makes as inserts, middle using steel core bar as centre post, utilizing crest line to thicken signature bar mould high-temperature molding makes bar shaped silica gel piece be combined the silica gel signature bar that formation crest line thickens with steel core bar high density, each layer yarn material is produced pressure by the thermal expansivity utilizing bar shaped silica gel piece, make the epoxy resin cure being attached on each layer carbon fiber or glass fiber yarn material, and combine closely between each layer yarn bed of material, make product inwall form the silica gel thickened with crest line and give as security the product coarse embryo inwall effect of bar appearance respective shapes.
Although bar molding given as security by corner of the prior art silica gel can meet the requirement producing the thick embryo of club, but the thick embryo product quality instability of club that bar forms out given as security by corner silica gel, and club wall thickness, intensity are unstable, cause unstable properties, and bad scrappage is higher.
The irregular thick embryo of inwall club that the silica gel signature bar that crest line thickens is made has the inner wall shape of uniqueness, the silica gel signature bar thickened at the crest line being inserts with silica gel material expands under forming temperature and extrudes each layer carbon fiber or glass fiber yarn material, so that the thick embryo inwall of club that the thick embryo of the club thick embryo inwall made becomes wall thickness inconsistent, club crest line wall thickness can be effectively improved, make constant product quality, improve conforming product rate, reduce production cost.
Therefore, the manufacture method of the thick embryo of club that inner wall thickness designed by the present invention is inconsistent, the thick embryo of club produced has more multi-functional and improves the thick embryo fraction defective of club, make the thick embryo intensity stabilization of club made, ball-handling several times fast, handle effect is good, crest line uniform wall thickness, stay-in-grade feature.
There is advantages that
(1) save silica gel and give as security bar inserts silica gel cost；
(2) improve the thick embryo quality of the thick embryo of club, improve bad scrappage；
(3) it is effectively improved the thick embryo crest line wall thickness of former corner rule club, makes product more multifunction.
