Abstract
The utility model discloses an evaporative pattern casting sand box. The evaporative pattern casting sand box comprises an outer sand box protection plate, a negative pressure chamber, side plates, a vacuumizing port and lifting lugs, wherein each side plate is connected with the corresponding lifting lug; the negative pressure chamber is positioned between the outer sand box protection plate and the side plates and is connected with the vacuumizing port. The evaporative pattern casting sand box is characterized in that a stainless steel standard air plug is arranged at a joint of the negative pressure chamber and the side plates. An outer pressing plate and two layers of stainless steel screens are eliminated, and ventilation holes are formed in the stainless steel standard air plug. The air plug no longer needs to be replaced and only needs to be blown once regularly so as not to be blocked, the later-stage maintenance cycle is long, the cost is reduced, and the yield of castings is favorably improved.
Description
Technical field
The utility model relates to a kind of casting sandbox, relates in particular to a kind of lost foam casting sandbox.
Background technology
The casting dimension shape of lost foam casting is accurate, surface smoothness is high, duplicating property is good, is widely used in hot investment casting.Castability is received the impact of sandbox to a great extent.Fig. 2 is the aspirating hole partial schematic diagram of traditional sandbox negative pressure chamber, is from left to right outer plate 11,100 order stainless steel mesh 12,40 order stainless steel mesh 13 successively, outer panel 14, and sandbox negative pressure chamber exterior panel 16, has air-vent 15 on outer panel 14.Use traditional sandbox of this design, using a period of time dust can get lodged in the air-vent in screen cloth outside, easily damaged bad blocking of screen cloth after long-time, when cast, negative pressure can not improve or sand is pumped in the negative-pressure pipeline outside sandbox, have a strong impact on product quality, and average every three months left and right needs to change screen cloth one time, and one day ability of every 2 people is changed a sandbox.(replacing) maintenance cost is very high as can be seen here.
Summary of the invention
The purpose of this utility model is to provide a kind of easily cleaning tamper, need not often change the lost foam casting sandbox of screen cloth.
The utility model is realized like this.A kind of lost foam casting sandbox, comprise sandbox outer casing, negative pressure chamber, side plate, vacuum orifice, hanger, side plate surrounds sandbox casing, side plate is connected with hanger, negative pressure chamber is between sandbox outer casing and side plate, negative pressure chamber connects vacuum orifice, it is characterized in that negative pressure chamber and side plate junction adopt stainless steel standard vent plug.
As of the present utility model further preferred, four sides of described sandbox all arrange negative pressure chamber.
The beneficial effects of the utility model are: the utility model has been cancelled outer plate and two-layer stainless steel mesh, will in air-vent, insert stainless steel standard vent plug.Forever air exchanging plug more, only needs regularly (3-5 months) blow stainless steel standard vent plug one time with compressed air (0.6mpa), does not make its obstruction.Negative pressure chamber is formed by the bending of 6mm steel plate, in playing negative pressure chamber's effect, good reinforcement effect has also been played in sandbox periphery, improves more than 5 times service life compared with traditional design.Later period maintenance is long maintenance period, reduces cost, and is conducive to improve casting yield.
Brief description of the drawings
Fig. 1 is schematic diagram of the present utility model.
Fig. 2 is the aspirating hole partial schematic diagram of traditional sandbox negative pressure chamber.
Sandbox outer casing 2, negative pressure chamber 3, side plate 4, vacuum orifice 5, stainless steel standard vent plug 6, hanger 11, outer plate 12,100 order stainless steel mesh 13,40 order stainless steel mesh 14, outer panel 15, air-vent 16, sandbox negative pressure chamber exterior panel in the drawings 1.
Detailed description of the invention
For convenience of explanation, illustrate in detail the utility model below in conjunction with embodiment.
A kind of lost foam casting sandbox, comprise sandbox outer casing 1, negative pressure chamber 2, side plate 3, vacuum orifice 4, hanger 6, side plate 3 surrounds sandbox casing, side plate 3 is connected with hanger 6, negative pressure chamber 2 is between sandbox outer casing 1 and side plate 3, negative pressure chamber 2 connects vacuum orifice 4, it is characterized in that negative pressure chamber 2 and side plate 3 junctions adopt stainless steel standard vent plug 5.
Negative pressure chamber is formed by the bending of 6mm steel plate, and negative pressure chamber's width is 240mm.Stainless steel standard vent plug is diameter 5.8 standard stainless steel vent plugs.
