Metal die-casting machine nozzle device that can spray evenly

Abstract

A nozzle device for a metal die-casting machine capable of uniform spraying, comprising a base unit, a main sprayer and a main nozzle unit. The base unit includes a recessed seat hole on one side and a guide hole connected to the seat hole. The main sprayer is installed on the base unit and has a main nozzle connected to the seat hole. The main nozzle Can selectively spray water, release liquid, or a mixture of the two, the main nozzle unit can be detached and installed in the seat hole, the main nozzle unit has a main nozzle seat, and several connections on the main nozzle of the main nozzle seat. The main nozzle unit can be detached and installed in the seat hole, and can be quickly replaced according to the needs of use, and the mixing tank of the main nozzle seat is circular, and each of the main nozzles An inner port is equidistant from the main axis of the main spray seat, which can achieve the purpose of uniform spraying.

Description

technical field [0001] The invention relates to a metal die-casting machine, in particular to a nozzle device for a metal die-casting machine capable of uniform spraying. Background technique [0002] Existing metal die-casting machines need to spray release liquid onto a male mold and a female mold before die-casting operation, so that the casting can be ejected smoothly. The release liquid is sprayed by a spraying device, and the spraying device has several nozzles arranged side by side, and the nozzles are nozzles formed by bending copper pipes. After the die-casting is completed and the casting is taken out, the spray device will be driven between the male mold and the female mold, and the release liquid (a mixture of water and release liquid) will be sprayed out using the spray pipe to allow the release liquid to adhere to the mold. The surfaces of the male mold and the female mold close the mold, and continue the metal die-casting process of the next cycle. [0003] ...

AI Technical Summary

Problems solved by technology

[0006] 1. When the male mold and the female mold are replaced, the spray pipe of the spray head cannot be disassembled from the corresponding body (because it takes time and the accuracy of the corresponding male mold and female mold needs to be adjusted when reinstalling after disassembly), And it is necessary to disassemble the entire set of nozzles in order to achieve a faster replacement. However, the difference between the molds to be replaced may only be localized. Disassembling the entire set of nozzles is too time-consuming and affects production capacity.

[0007] 2. The air outlet of the atomizer directly corresponds to the outlet of the spray tube, and the atomized release liquid may still be sprayed out directly, and the atomization amount of each atomizing tube may still not be very high. Uniformity, so that the uniformity of the air and release liquid sprayed through the nozzle unit of the nozzle unit is not enough, and the atomization effect is not good

[0008] 3. For the side module, and the deep holes set in the male mold, the female mold and the side module cannot produce a better spraying effect of the release liquid
