Abstract
The invention relates to a sealing mechanism for a sand unloading door of a sand mixer. According to the technical scheme provided by the invention, the sealing mechanism for a sand unloading door of a sand mixer comprises a sand unloading door body characterized in that an elastic sealing ring is arranged at the peripheric edge of the sand unloading door. The outer diameter of the elastic sealing ring increases gradually from front to back facing the direction of the inner side of the sand mixer. The invention has simple and skillful structure, convenient assembly and good sealing property and can prevent sand leakage at the door crack of the sand unloading door in the process of molding and mixing sand by the sand mixer and ensure that the equipment is integral in the process of sand mixing and the work site is environmental-friendly. The invention can be assembled according to the size of the sand unloading door and meets the requirement of sealing the sand unloading doors of the rotor sand mixer or those of the same structure. The elastic sealing ring is made of polyurethane material and has long service life.
Description
Technical field
The invention belongs to the apparatus for casting technical field, relate to a kind of puddle mixer and unload the sand door, specifically a kind of sealing mechanism for sand unloading door of sand mixer.
Background technology
In foundry production, the molding sand system of mixing is the indispensable unit in the sand preparing system, and puddle mixer just molding sand mix main equipment in the system unit.Existing puddle mixer mixes in the system process at molding sand, the sand door occurs unloading through regular meeting and leaks the sand situation, not only causes the waste of molding sand, sometimes also can enter in other equipment, causes other equipment to produce fault.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, provide a kind of simple and ingenious structure, easy to assembly, good sealing effect, the sealing mechanism for sand unloading door of sand mixer of long service life.
According to technical scheme provided by the invention, described sealing mechanism for sand unloading door of sand mixer comprises and unloads sand door body that it is characterized in that: elastic sealing ring is equipped with in described neighboring of unloading sand door body; Before with the direction towards the mulling internal body being, the external diameter of described elastic sealing ring increases from front to back gradually.
As a further improvement on the present invention, be concaved with the O type groove with the elastic sealing ring concentric on the rear end face of described elastic sealing ring, be inlaid with O type sealing strip in this O type groove.
As a further improvement on the present invention, the described sand door body that unloads comprises the stacked first fixing door-plate, second door-plate and base plate, the external diameter of first door-plate and base plate is greater than the external diameter of second door-plate, the neighboring of first door-plate, second door-plate and base plate forms annular groove, described elastic sealing ring is inlaid in this groove, and the front end external diameter of elastic sealing ring is identical with the rear end external diameter of first door-plate.
As a further improvement on the present invention, the rear end external diameter of described first door-plate is greater than the front end external diameter.
As a further improvement on the present invention, described elastic sealing ring adopts polyurethane material to be made.
The present invention compared with prior art, advantage is: simple and ingenious structure, easy to assembly, good seal performance, can prevent effectively that sand mixer from unloading the leakage sand of sand every seam in the process of molding sand mulling, guarantee that molding sand mixes the Plant in good condition of system process, the feature of environmental protection of work-yard.The present invention can be equipped with according to unloading sand door size, satisfies the sealing that rotator mixer or structure of the same type are unloaded the sand door; Elastic sealing ring adopts polyurethane material to make long service life.

Fig. 3 is an application schematic diagram of the present invention.
Description of reference numerals: 1-unloads sand door body, 2-elastic sealing ring, 3-first door-plate, 4-second door-plate, 5-base plate, 6-O type groove, 7-O type sealing strip, 8-mulling body.
The specific embodiment
The invention will be further described below in conjunction with concrete drawings and Examples.
As shown in the figure: described sealing mechanism for sand unloading door of sand mixer comprises and unloads sand door body 1, in the neighboring of unloading sand door body 1 elastic sealing ring 2 is housed, with direction be towards mulling body 8 inside before, the external diameter of described elastic sealing ring 2 increases from front to back gradually.In order to improve the service life of elastic sealing ring 2, described elastic sealing ring 2 preferred employings polyurethane material wear-resistant, high abrasion resistance is made.
As shown in Figure 2,, be concaved with the O type groove 6 with elastic sealing ring 2 concentrics on the rear end face of described elastic sealing ring 2, be inlaid with O type sealing strip 7 in this O type groove 6, to reach the effect of inner elastomeric in order to improve the sealing property of elastic sealing ring 2.
As shown in Figure 1 and Figure 2, installation, dismounting and replacing for the ease of elastic sealing ring 2, the described sand door body 1 that unloads is mainly by adopting screw stacked fixing first door-plate 3, second door-plate 4 and base plate 5 to form, the external diameter of first door-plate 3 and base plate 5 is greater than the external diameter of second door-plate 4, the neighboring of first door-plate 3, second door-plate 4 and base plate 5 forms annular groove, described elastic sealing ring 2 is inlaid in this groove, and the front end external diameter of elastic sealing ring 2 is identical with the rear end external diameter of first door-plate 3; The rear end external diameter of first door-plate 3 is greater than the front end external diameter.
