Abstract

The utility model provides a coating spraying device in a mold. The coating spraying device comprises a die casting machine, wherein the mold is arranged in the die casting machine. The coating spraying device is characterized in that a pipe-shaped spraying pipe is arranged in the die casting machine; a plurality of spraying holes are arranged on the spraying pipe; coating is sprayed into the mold by the spraying holes; and the spraying pipe is movable. The coating spraying device provided by the utility model has the advantages that the spraying performance of the mold is improved, and the sprayability of dead corners and dark-side parts is improved; since a coating and compressed-air entering structure is added, the dark side of the mold can be correspondingly sprayed, and further the excellent spraying effect is achieved; and the dead corners and the dark-side parts of the mold can be prevented from being damaged due to the sticky mold, so that the service life of a complex mold is prolonged.

Description

Painting spraying device in a kind of mould

Technical field

The utility model relates to the interior painting spraying device of device, especially mould of sprayed coating in a kind of casting industry die casting.

Background technology

Die casting machine is a kind of common equipment of field shaping technique in the mechanical industry, is a kind of under pressure molten metal bath injection cooling forming in the die casting, obtains a kind of industrial machinery of solid metal foundry goods after the die sinking.

In order to strengthen the demolding performace of mould; Usually need in mould, spray releasing agent; The important procedure of sprayed coating in the die cavity of die casting (like releasing agent etc.) when being die casting; Usually spray with manual spray gun in the prior art, or on die casting machine, set flush coater, in die cavity, spray releasing agent through manual spray gun or flush coater.Spraying in the prior art has only could realize spraying coating to the mould exposed face; When spray paint; Could be sprayed onto coating on the mould the mould exposed face, when mould has the dead angle and the back (spray is less than the position of coating), just can not be sprayed onto coating on the dead angle and back position of mould; The dead angle of mould and back position do not have coating basically; Perhaps have only a very thin coating, cause the release property of mould mold cavity inhomogeneous, and the dead angle of mould and back position can be damaged because of sticking to mould.That is to say this spraying method or spraying equipment to the mould that the dead angle and the back are arranged can not realize the spraying.By the die casting industry characteristics, the frequent sticking to mould of compression mod can cause the phenomenon that often stops production.

Summary of the invention

To above-mentioned deficiency of the prior art, the main purpose of the utility model is to overcome the above-mentioned deficiency that prior art exists, and painting spraying device in a kind of mould is provided.The utility model has adopted a kind of novel spraying structure; Can be with the position that can not spray under the mould routine; Dead angle and back position like mould can both be sprayed onto coating; And in mould, the back is sprayed, can corresponding as required mould different facial make spray equipment, be particularly useful for the needs of complicated and large mold.

The technical scheme of the utility model is following: painting spraying device in a kind of mould, comprise die casting machine, and in die casting machine, be provided with mould; It is characterized in that: in die casting machine, the spray pipe of tubulose is set, spray pipe is provided with several spraying holes, through the spraying hole coating is ejected in the mould, and spray pipe is a packaged type.

Further characteristic is: said spray pipe is a kind of double-layer structure, is made up of outer tube and inner sleeve, and inner sleeve is arranged in the overcoat tube chamber in the middle of the outer tube, is provided with internal canula lumen in the middle of the inner sleeve; The spray pipe upper end is provided with inlet for pressurised gas and coating import, and inlet for pressurised gas is communicated with internal canula lumen, and the coating import is communicated with the overcoat tube chamber; Described spraying hole, correspondence is arranged on outer tube and the inner sleeve.

The upper end of spray pipe is connected in the push pedal of die casting machine dynamic model.

With respect to prior art, the utility model painting spraying device has following beneficial effect:

1, improves the spraying property of mould, but improved the sprayability at mould dead angle and back position.

2 and be added with coating and compressed air and get into structure, the spray equipment in mould can spray by the corresponding mould back, reaches good spraying effect.

3, prevent that mould dead angle and the back position from can damage because of sticking to mould, improve the service life of complicated die.

Description of drawings

Fig. 2 is a kind of concrete spray pipe structure cutaway view.

The specific embodiment

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described further.

Like Fig. 1, shown in 2, painting spraying device in the mould of the utility model comprises die casting machine 1, in die casting machine, is provided with mould 2 according to technological requirement, and mould 2 closes up the back and forms die cavity, and foundry goods is cooling forming in this die cavity.

The improvement of the utility model is in die casting machine 1, and the spray pipe 3 of tubulose is set; Spray pipe 3 is provided with several spraying holes 4; Specifically be provided with, coating (like releasing agent etc.) be ejected in the mould 2, cover on the forming surface of mould 2 through spraying hole 4 in stage casing and lower end; Spray pipe 3 is packaged types, and under the power set of die casting machine 1 drove, the power set that perhaps set separately drove down, upper and lower moving; The upper end of spray pipe 3 specifically can be connected in the push pedal 6 of die casting machine 1 dynamic model, follows push pedal 6 upper and lower moving., mould 2 (ejects the back) after opening; Spray pipe 3 stretches in the mould 2; With coating ejection in 4 from a plurality of sprayings hole, cover in the die cavity of mould 2 (on the forming surface), can parallel or ejection from the bottom up with respect to forming surface; With respect to the ejection from top to bottom of prior art, especially can make the dead angle of mould and back position can both be sprayed onto coating.

As shown in Figure 2; A kind of specific embodiment structure of the utility model spray pipe 3, spray pipe 3 is a kind of double-layer structures, is made up of outer tube 31 and inner sleeve 32; Inner sleeve 32 is arranged in the overcoat tube chamber 33 in the middle of the outer tube 31, is provided with internal canula lumen 34 in the middle of the inner sleeve 32; Spray pipe 3 upper ends are provided with inlet for pressurised gas 35 and coating import 36, and inlet for pressurised gas 35 is communicated with internal canula lumen 34, and coating import 36 is communicated with overcoat tube chamber 33; On sleeve pipe 31 and the inner sleeve 32, correspondence is provided with spraying hole 4 outside.Outside gases at high pressure and coating are respectively through inlet for pressurised gas 35 and coating import 36; Get in the spray pipe 3, be fed in spraying hole 4 through internal canula lumen 34 and overcoat tube chamber 33 respectively, when needing spraying; Under the control of the control device on the die casting machine 1; With the open and close synchronised of mould 2, under the pressure effect of Compressed Gas, with the 4 interior ejections of the coating in the overcoat tube chamber 33 from a plurality of sprayings hole; Cover the die cavity interior (on the forming surface) of mould 2, especially can make the dead angle of mould and back position can both be sprayed onto coating.

Need to prove; Above embodiment is only in order to explain the utility model technical scheme but not the restriction technologies scheme; Although the applicant specifies the utility model with reference to preferred embodiment, those of ordinary skill in the art should be appreciated that those technical schemes to the utility model make amendment or be equal to replacement; And do not break away from the aim and the scope of present technique scheme, all should be encompassed in the middle of the claim scope of the utility model.
