First method: split plot design after the first molding.
1, die shape processing: select the thick multilayer board of 15---18mm (density board, acrylic board, pine, bakelite, bakelite, resin plate etc. all can) for use; Carve out the violin inner mold with engraving machine according to data and (comprise up and down the breach of totally 6 angle blocks; This procedure also can artificially be made with carpenter's saw, but wants after finishing figure on the sheet material, to reprocess earlier).
2, mould side perforate:, open two circular holes to mold center perpendicular to angle block with dividing during planer drill bit (or electric hand drill) is respectively in angle block breach up and down according to dimensional requirement.Same operation, about 4 angle block breach middle parts open a circular hole respectively.Divide equally at 6 side plate positions successively then and respectively open two circular holes, all circular holes are for the circle such as grade and less than 10mm, the degree of depth is less than 50mm.
3, splint construction: selecting 2 thickness for use is 3-5mm corrosion resistant plate or copper coin (requiring the material with the high difficult deformation of hardness); Cut into the sheet material of shape but outer identical less than mould with mould; Then mould being lain on the clamping plate with the cross curve is to align around the benchmark; 6 the angle block breach outline lines that draw fall clamping plate unnecessary place sawing according to setting-out.After with mould place align in the middle of the two clamping plates fixing, according to drawing with bench drill at the clamping plate center and periphery beat some open-works (fixed mould usefulness), afterwards screw thread is processed in the hole on the following clamping plate, it is fastening to be used to tighten up a screw.
4, die face fluting perforate: will go up lower plate and mould and fit, will go up lower plate through the circular hole on the clamping plate and mould is fastening, and open groove in getting with milling cutter above the die side face according to drawing afterwards, beat open-work with screw.
5, fixed processing bar: fixed bar core matter is hardwood, and crust is stainless steel or copper pipe (also can directly use hardwood without crust), and is cylindrical; Length is less than circular hole degree of depth 8mm; Diameter is advisable just can be free to slide in the patchhole, forward bores two diameter 3-5mm holes at the bar end, and two hole external diameter spacings are less than fluting internal diameter 3-5mm; Subsequent use diameter 3-5mm length 15mm steel bolt can insert in the hole and not and slidably be advisable.
6, processing angle block pad: select hardwood or resin, bakelite, metal for use, cut into respective shapes according to the figure paper size and get final product.
7, mould is cut apart and is processed module: will go up lower plate and take off, the mould sawing become four according to drawing, and promptly up and down each one, about center section each one.
8, fixed tray: select two of multilayer board or solid woods for use; Similar and the size of shape and mould is greater than mould (wherein bottom plate is greater than mounting plate), and it is smooth smooth to be trimmed to pros and cons, mould is placed on the center aligns on the mounting plate; Open two holes according to the fixed orifice of mold center, built-in woodenware nut.Then the mould limited screw is tightened, and be fixed into one with screw and bottom plate.Along 150mm delineate line, 16 jump rings are installed in the outline line neighboring again according to drawing apart from the mould outer.
9, external fixation wooden unit: first wood and tail tree fixedly wooden unit are selected transparent acrylic material for use; Joint close bar and gim peg are stainless steel; Other fixed block is a wood materials, and fixedly wooden unit inner spring circle selects moderate spring leaf or the rubber of elastic force to do cylindrical barrel, combine with wooden unit.Concrete manufactured size is decided according to drawing requirement.
10, mould assembling: will go up lower plate and mould holder earlier and lump together with screw fasteningly, and again spring put into the die side face, then with the fixed bar insertion, again with the circular hole on the subsequent use contact pin insertion fixed bar.Fixed bar installs back (angle block breach in place pad) and it is exposed an end (side plate one end) repairs, and polishes the termination with sand paper, flushes with breach and mould circular arc side to be as the criterion.Mould is placed on the fixed tray, mould and pallet can be carried out the side plate production process after fixing with screw rod.
Second method: cut apart back molding method earlier.
This method complex operation is not so recommend.
Because die main body of the present invention is by four modules and two clamping plates and 20 fixed bars and 6 pads constitute up and down; Module flat assembling is inserted after fastening with clamping plate again fixed bar and pad the violin internal mold (also can make very easy assembling die in addition; Do not want fixed bar and pad; Just the combination of four modules and last lower plate gets final product, but this mould must peel off mould with angle block with the parting cutter and repair when the later stage demoulding, and if be with mould that side plate and backboard are repaired angle block after bonding again and damaging backboard easily; And polishing finishing etc. are very inconvenient, and the mould of band fixed bar just can be avoided above-mentioned drawback).Therefore, though split of the present invention combination external fixation formula mould is development on the whole board-like mold foundation of one, the die shape after the assembling is the same with whole board-like die shape; But their key distinction is: whole board-like (an only plate) mould of one can not be split; And take interior support fixation when making side plate, promptly anchor clamps will be clipped on the mould, and it is solid inelastic that the angle block fixed block is arranged again; And sectional die of the present invention (split) can split; Take outer support fixation when making side plate, promptly anchor clamps are clipped in outside the mould, and the fixed block inboard is that hollow arbor braid is flexible; And angle block can be seen tail seam butt joint situation intuitively with transparent acrylic up and down, the adjustment in time of pinpointing the problems.Elasticity joint close bar then can prevent to move return with side plate independently to the center extruding.Simultaneously,, make up up and down because split of the present invention combination external fixation formula violin mould can be dismantled by piecemeal, so,, will not take out by mould side plate after making moulding, directly can repair angle block.And after all finishing process of side plate are all accomplished, can be with mould disposable gluing within a short period of time directly to carry out bondingly with backboard,, panel getting final product the mould taking-up again when making the completion preparation and close qin at last.Adopt this mould, can guarantee fully side plate and mould in system qin process all the time disjunctor rely on, fundamentally solved because of shifting to an earlier date problems such as side plate easy deformation that mold removal brings and gluing difficulty.In addition, mould is fixed on the purpose-made pallet, when bonding angle block and side plate; Can guarantee its steadiness and verticality; And when side plate finishing finish wait for this that closes qin during, it is fixing still can to reset, and plays more firm effect to guaranteeing that backboard and side plate are indeformable.There are fixed tray and outer grip device that the wright can be fixed very easily, polish again and repair side plate.
