Technical field
The invention belongs to the metal casting field of mechanical technique, be specifically related to a kind of Novel mold releasing agent spraying device for die casting and squeeze casting mould.
Background technology
The mould of die casting machine, extrusion casting machine all need spray releasing agent so that foundry goods is easy to the demoulding before carrying out the foundry goods operations for forming.Existing and die casting machine, the supporting mold releasing agent spraying device of extrusion casting machine mostly are the device of shifting block type spray equipment, when carrying out spraying operation, nozzle component on it is relative with the position of mould fixing, therefore be unfavorable for even spraying, spray time is longer, and when being used for the mould of spraying large-scale circular, subcircular foundry goods (such as automotive hub), spraying effect is not satisfactory.
Summary of the invention
The object of the invention is to for the deficiencies in the prior art part, a kind of Novel mold releasing agent spraying device that adopts the rotary spraying mode is provided, to improve coating quality, shorten spray time.
For achieving the above object, the present invention adopts following technical scheme:
Novel mold releasing agent spraying device comprises a mount pad, and described mount pad is provided with the gentle motor of outer shaft, is provided with rotating shaft in the outer shaft; Described rotating shaft is connected with the gas motor by transmission component; Be provided with at least one shaft orientation flowing channel in the described rotating shaft, every shaft orientation flowing channel forms respectively a runner exit in the two ends of rotating shaft, and corresponding every shaft orientation flowing channel is provided with a radial flow path, and each radial flow path forms a runner entrance in the lateral surface of rotating shaft; Corresponding each the runner entrance of the madial wall of described outer shaft is provided with a cannelure, and corresponding every cannelure is provided with an input duct, and each input duct forms an input port in the lateral wall of outer shaft; The two ends of described rotating shaft are respectively equipped with a rotating disk, and each rotating disk is provided with nozzle component, and described nozzle component is communicated with the runner exit of homonymy by pipeline.
As preferably, described shaft orientation flowing channel is at least two.
Further, the both sides of each cannelure are provided with sealing ring.
As preferably, the two ends of described rotating shaft are respectively equipped with a pipeline connecting plate, and corresponding each runner exit of each pipeline connecting plate is provided with a connected chamber, and each connected chamber forms connector on the pipeline connecting plate, and described nozzle component is connected with this connector by pipeline.
As preferably, described transmission component is comprised of pinion and gear wheel, and pinion is located on the gas motor drive shaft of gas motor, and gear wheel is located in the rotating shaft and and pinion.
As preferably, described rotating shaft vertically arranges.Further preferred, be positioned at the disk diameter of rotating shaft upper end greater than the disk diameter of rotating shaft lower end.
The present invention is by adopting said structure, have advantages of that the releasing agent spraying is more even, spray area is larger, spray time is shorter, operating efficiency is higher and the scope of application is wider, is particularly useful for the releasing agent spraying operation of the mould of large-scale circular, subcircular foundry goods (such as automotive hub).

Now in conjunction with the accompanying drawings and embodiments the present invention is described in further detail:
The specific embodiment
As shown in Figure 1, Novel mold releasing agent spraying device of the present invention has a mount pad 1, is provided with outer shaft 11 gentle motors 12 on the mount pad 1, by bearing 7 rotating shaft 2 is set vertically in the outer shaft 11.The upper end installing gear wheel 92 of rotating shaft 2, installing pinion 91 in the rotating shaft of gas motor 12, pinion 91 and the gear wheel 92 intermeshing gas motor drive shafts 2 that make are rotated.
Be provided with some shaft orientation flowing channels 21 (quantity of shaft orientation flowing channel is set according to the quantity of fluid media (medium)) in the rotating shaft 2, every shaft orientation flowing channel 21 forms respectively a runner exit 24 in the upper and lower sides end face of rotating shaft 2; Corresponding every shaft orientation flowing channel 21 has a radial flow path 22 that is communicated with this shaft orientation flowing channel, and every radial flow path 22 forms a runner entrance 23 in the lateral surface of rotating shaft.Corresponding each the runner entrance 23 of the madial wall of outer shaft 11 is provided with a cannelure 111, and the both sides of every cannelure 111 are respectively equipped with sealing ring 6; Corresponding every cannelure 111 is provided with an input duct 112 that is communicated with this cannelure, every input duct 112 forms an input port 113 in the lateral wall of outer shaft 11, and the multiple fluid media such as releasing agent, water and compressed air can be by those input port inputs.
Upper and lower sides end face in rotating shaft 2 is respectively equipped with a pipeline connecting plate 5, and these pipeline connecting plate 5 each runner exits of interior correspondence are provided with a connected chamber 51, and each connected chamber 51 is connector 52 of 5 formation on the pipeline connecting plate.Between pipeline connecting plate 5 and the rotating shaft side end face seal washer 8 need be set, to prevent between the different fluids revealing mutually and to outward leakage.Be provided with top rotary table 31 in the upper end of rotating shaft 2, the lower end of rotating shaft 2 is provided with lower rotary table 32, the diameter of top rotary table 31 is greater than the diameter of lower rotary table 32, and be equipped with one group of nozzle component 4 on top rotary table 31 and the lower rotary table 32, every group of nozzle component 4 all is communicated with connector 52 on the pipeline connecting plate of the same side by flexible pipe (not shown in FIG.).
When the present invention works, rotated by gas motor drive shaft, and the multiple fluid media such as releasing agent, water and compressed air enter respectively from a plurality of access ports of outer shaft, pipeline connecting plate and flexible pipe through separately input duct, radial flow path, shaft orientation flowing channel, rotating shaft two ends enter in the nozzle component, go through the shower nozzle ejection again, because upper and lower rotating disk is by the rotating shaft driven rotary, therefore can be simultaneously the upper die and lower die of die casting machine/extrusion casting machine mould be rotated spraying operation, spray area is large and even, spray time shortens, and has greatly improved operating efficiency.Also have, because the area of top rotary table is greater than the area of lower rotary table, therefore top rotary table has the bits of connecing function in the course of the work, can prevent that the casting fin, residue etc. in the patrix from falling in the counterdie.
