Description

The carbon fibre rim mould

Technical field

The utility model relates to a kind of technology of vehicle wheel rim, is meant a kind of one-body molded mould that goes out tire groove and overhead kick size of carbon fibre rim that makes especially.

Background technology

TaiWan, China patent announcement I236983 patent case discloses a kind of manufacture method of bicycle rim, and step is as follows:

A. composite wood is coated on the mould heart 20 outer rims of moulding in advance, in order to housing 11 is formed out, this mould heart 20 is to be made by silica gel, and can change shape on demand;

B. utilize composite wood that inside casing 12 rows are built up type;

C. will arrange folded housing of finishing 11 and inside casing 12 and insert in the mould 50 hot-formingly, and and housing 11 be engaged with inside casing 12, and, inside casing 12 can be fitted perfectly take shape in the inwall of mould 50, in order to mold a wheel rim 10 with in the gas injection inside casing;

D. the mould heart 20 in wheel rim 10 housings 11 is taken out, grind this wheel rim 10 of repairing then and can finish.

Be to mold the tire groove in the housing 11 of described wheel rim 10 with the mould heart 20, these tire channel opening both sides necessarily have overhead kick, the tire of the tool inner tube of a tyre can be installed in this tire groove, this overhead kick meeting interferes with the demoulding, and for this reason, the mould heart 20 must be with the heat-proof silica gel manufacturing, so could be after housing 11 moulding, the operator forces to make 20 distortion of the mould heart, could can reuse in order to this mould heart 20 by taking out in the housing 11 again.

This mould heart 20 is owing to be to adopt the one-body molded manufacturing of silica gel, it has the physical characteristic of quality softness, buffering distortion, cause it when moulding housing tire groove and overhead kick, have size and the low problem of superficiality accuracy rate, therefore must after the demoulding, grind and repair, and this grinding and repair to adopt and manually repeat, it not only accumulates man-hour because of action frequency increases, the operating efficiency that wheel rim 10 is finished also can't promote, more be difficult to increase economic efficiency, this is that present process technology can't break through part.

Have fraction defective high and time-consumingly take a lot of work again because commonly use the carbon fibre rim manufacturing, so that cost is surging, the shortcoming that quality, efficient can't promote is professional experiences and the gains in depth of comprehension with for many years, grind through constantly conceiving, creating, and be to develop the utility model.

The utility model content

The purpose of this utility model is to provide a kind of carbon fibre rim mould, and the mould heart can adopt metal or other hard material manufacturing, therefore can make wheel rim tire groove, overhead kick size and the superficiality accuracy rate of moulding higher.

For reaching above-mentioned purpose, the utility model is adopted following scheme:

A kind of carbon fibre rim mould, it is made up of upper die and lower die and middle mould; These upper die and lower die have can be to the ring-type die cavity of synthesis type carbon fibre rim outer surface, and upper die and lower die are provided with one in the die cavity periphery in addition and hold the cave; This middle mould is circumferential arrangement and is positioned in this appearance cave.Should in mould be to add folded the composition with a plate in the upper plate, one and a lower plate, and upper plate, middle plate and lower plate all have the mould heart that can stretch into die cavity relatively, these mould gains in depth of comprehension are to mold the tire groove and the overhead kick of carbon fibre rim.

This upper plate, middle plate and lower plate are with having the mould heart that can stretch into die cavity, and this three moulds heart is and adds folded the setting, should go up the groove that template die heart end face is concaved with an energy moulding carbon fibre rim overhead kick, this time template die heart bottom surface then be concaved with one can moulding the groove of another overhead kick of carbon fibre rim, intracardiac week of template die in this, go up template die heart end face and in week, down template die heart bottom surface and in form a plastic tire groove that goes out carbon fibre rim week.

These upper die and lower die respectively are concaved with the appearance cave of a tool class in the die cavity periphery, and this holds cave and is made up of a bypass road and an interior circuit; Middle plate has the block that can be positioned in the bypass road, and formation one can be kept supplying upward takeing on of plate assembling between its mould heart end face and the block, and upper plate has the ring piece that can be positioned the interior circuit of patrix in addition; In plate also between mould heart bottom surface and block, form one can be for the following shoulder of lower plate assembling, lower plate and have the ring piece that can be positioned circuit in the counterdie.

These upper die and lower die are disc-shape, and both central authorities have an open-work that runs through up and down, and the die cavity of upper die and lower die is provided with open-work is concentric.

This counterdie is provided with the location female seat in open-work, patrix then be provided with the location male seat that cooperates.

This upper die and lower die involutory surface is between open-work and die cavity, and other is provided with the intermeshing flank of tooth of energy, and this flank of tooth is trapezoidal shape.

A plurality of perforation have been provided respectively in middle plate, upper plate, lower plate.

After adopting such scheme; the utility model is mainly by the design of mould in these special three layers; during the demoulding; need only remove patrix or counterdie; middle mould and wheel rim are taken out in the lump; middle plate is extracted out; can make the involutory constriction of upper plate and lower plate; by deviating from tire groove and the overhead kick; carry out the demoulding smoothly, make the mould heart can adopt metal or other hard material manufacturing, and case must be with the shortcoming of soft silica gel manufacturing before can changing patent; therefore wheel rim tire groove, overhead kick size and the superficiality accuracy rate of institute's moulding are quite high, promote quality effectively, enhance productivity.

Below with preferred embodiment and conjunction with figs. the utility model is elaborated.
