Abstract

The invention provides a painting mold of a varnished wire. The painting mold can solve the problem that an existing painting mold is not prone to replacement and can effectively avoid the phenomenon that in the painting process, insulation varnish is wasted. The painting mold comprises a mold core and a mold sleeve; the mold core is arranged in the mold sleeve; and the painting mold is characterized by further comprising an upper cover plate and a lower cover plate. The mold core is formed by splicing a left half mold core body and a right half mold core body; and the mold sleeve is formed by splicing a front half mold sleeve body and a rear half mold sleeve body; the front half mold sleeve and the rear half mold sleeve are placed to be mounted on the periphery of the mold core, and the mold core is packaged in the mold sleeve through the upper cover plate and the lower cover plate; and the upper cover plate and the lower cover plate are in fastened connection with the mold core and the mold sleeve respectively through bolts.

Description

The japanning die of enamel-covered wire

Technical field

The present invention relates to the processing unit (plant) field of enamel-covered wire, be specially the japanning die of enamel-covered wire.

Background technology

The enamelling process of current enamel-covered wire generally has felt method to paint and die methods japanning, wherein the japanning of felt method has easy to operate, exchange wire gauge advantage easily, but the viscosity requirement of the method to insulated paint is higher, and paint film is wayward, needs often change felt and insulated paint is vulnerable to pollute thus affects the insulating properties of enamel-covered wire, and adopt of die methods japanning fixes japanning die 2 more, insulated paint is stored in paint cylinder 3, bare copper wire 1 from bottom to top through paint cylinder 3 after again through japanning die 2, see Fig. 1 and Fig. 2, japanning die 2 wherein comprises mould cover 2-1 and core rod 2-2, core rod 2-2 is installed in mould cover 2-1 by jump ring 2-3 in fact, its film thickness is easy to control, japanning precision is high, but need to change corresponding japanning die when processing different size enamel-covered wire, generally that bare copper wire is cut off at first mould place during replacing, then corresponding mould is changed, again the bare copper wire cut off is welded to connect, therefore its to there is die change loaded down with trivial details, labor strength is large, inefficient problem, and more during mold exchange, bare copper wire welds after cutting off again and also directly results in scrapping of bare copper wire, cause the waste of bare copper wire, in addition, existing die methods japanning is stored in paint cylinder due to edge paint, there is the phenomenon of the waste of insulated paint in lacquering process.In Fig. 1,4 is felt.

Summary of the invention

For the problems referred to above, the invention provides the japanning die of enamel-covered wire, it can solve and adopt the not easily changeable problem of existing japanning die, and effectively can reduce the insulated paint wasting phenomenon existed in lacquering process.

The japanning die of enamel-covered wire, it comprises core rod and die sleeve, described core rod is installed in die sleeve, it is characterized in that: it also comprises upper cover plate and lower cover, described core rod is made up of left half core rod and right half core rod split, described die sleeve is made up of first half die sleeve and later half die sleeve split, described first half die sleeve and later half die sleeve split are installed on the surrounding of described core rod, described core rod is packaged in described die sleeve by described upper cover plate, lower cover, and described upper cover plate, lower cover are respectively and described core rod, to be bolted connection between die sleeve.

Further, described core rod is installed on the top of described die sleeve, and the cavity between the bottom surface of described core rod and described lower cover is formed and stores up paint bath, described upper cover plate, be bolted between core rod and die sleeve fixing.

Further, described first half die sleeve and back mold half have into paint hole, described in enter to paint hole connect paint inlet tube.

The beneficial effect of japanning die of the present invention is: its core rod and die sleeve are split structure half-and-half, core rod is packaged in die sleeve by upper cover plate and lower cover simultaneously, its easy accessibility, no longer need during die change to cut off bare copper wire, therefore greatly can improve the replacing efficiency of mould and avoid because of more mold exchange and damage to naked copper money, and reduce scrapping and waste of bare copper wire, save production cost; In addition, its core rod is installed on the top of mould cover, thus between die sleeve and lower cover, form storage paint bath, first half die sleeve and back mold half have into paint hole, enter to paint hole and connect paint inlet tube, insulated paint is conveyed in the storage paint bath of mould by paint inlet tube, therefore insulated paint to be closed in mould thus effectively can to avoid the waste of insulated paint, also insulated paint can be avoided contaminated, ensure that the quality of production of enamel-covered wire.
