Abstract
The invention relates to a venting device for a molding machine. The venting device comprises a compaction table, an upper box, a molding board, a middle box and a venting mechanism. The venting mechanism is fixed on the compaction table through a fastening device and the molding board is located under the venting mechanism; the molding board is connected with the middle box and the upper box is located at the upper part of the middle box; the upper box is fixed through the fastening device and a bracket is arranged at the upper part of the compaction table; the bracket is provided with an air cylinder and one end of a piston of the air cylinder is connected with the fastening device. In the invention, the venting device can be used for venting accurately in the process of molding due to the accurate position of an air vent and water vapor and other gases which are generated on the surface of a sand mold can be discharged in time, which is good for quick filling of metal liquid and alleviation of the arching function of high-temperature air flow on the sand mold surface layer and beneficial to the backward moving of a water condensation zone and reduction of the water content of the water condensation zone.
Description
Technical field
The present invention relates to a kind of foundry machinery, be specifically related to a kind of novel moulding machine venting device.
Background technology
In the production process of foundry goods, if foundry goods vertical direction size is bigger, when cast, molten iron is difficult to gas is discharged after flowing into peak, causes cast(ing) surface to have sand holes or foundry goods that damaged phenomenon is arranged.For avoiding the generation of this phenomenon, generally after mould assembling, on the sand mold of top box, prick several cores, play scavenging action.So the operation of venting is an indispensable operation in the castings production process.At China's venting generally all is that operating personnel take air tube manual dazzling, and more advanced in the world method is to prick the exhaust eye with special venting machine.No matter be that craft is dazzling or machine is dazzling, the core position all will be estimated by operating personnel, tends to cause the core biasing, the consequence that exhaust is not smooth.
Summary of the invention
The present invention has overcome the deficiency of prior art, has proposed a kind of novel moulding machine venting device, and said device adopts combined type venting device, is directly installed on the compacting table top of moulding machine, realizes one with moulding machine; Adopt the spring compression form, when vent wire touched template, the spring compression avoided damaging template; According to the shape of model on the template, confirm the position of venting device, guaranteed the accuracy of institute venting position.
Technical scheme of the present invention is: a kind of novel moulding machine venting device; Comprise compacting platform, top box, template, raising middle flask and venting mechanism, said venting mechanism is fixed on the compacting platform through fastener, and said template is positioned at the below of said venting mechanism; Template and raising middle flask link together; Said top box is positioned at the top of raising middle flask, and top box is fixed by said fastener, is provided with support on the top of compacting platform; On said support, be provided with cylinder, an end and the said fastener of the piston of said cylinder link together;
Said venting mechanism comprises loam cake, spacer, axle sleeve, spring and air tube, and said axle sleeve inside is provided with cavity, and loam cake and spacer link together, and are used for said spring is fixed in the said cavity; The top of said air tube is fixed together through fixture and said spring, and said venting mechanism is connected with said compacting platform through said axle sleeve.
Said compacting platform is provided with the control system, and said cylinder links to each other with said control system through holding wire.
The present invention has following beneficial effect:
1) adopts combined type venting device, be directly installed on the compacting table top of moulding machine, realize one with moulding machine;
2) adopt the spring compression form, when vent wire touched template, the spring compression avoided damaging template;
3) according to the shape of model on the template, confirm the position of venting device, guaranteed the accuracy of institute venting position;
4) the present invention has realized the process of venting in upper and lower case mould assembling modeling process, has saved independent venting operation, saves the moulding time, has improved productivity ratio;
5) the core position is accurate; Venting accurately in modeling process; Can get rid of steam and other gas that the sand mold top layer produces in time; Can help the quick filling of metal liquid and alleviate the rise arch action of high temperature gas flow, be of value to making and move behind the moisture condensation region and reduce moisture condensation region moisture the sand mold top layer.
Description of drawings
Further specify the present invention below in conjunction with the accompanying drawing and the specific embodiment.
Fig. 1 is a structural representation of the present invention.
Fig. 2 is a venting mechanism structure sketch map of the present invention.
Among the figure, 1, the compacting platform; 2, top box; 3, venting mechanism; 4, template; 5, raising middle flask; 6, control system; 7, cylinder; 8, support; 9, fastener; 10, loam cake; 11, spacer; 12, axle sleeve; 13, spring; 14, air tube.
The specific embodiment
Further specify below in conjunction with accompanying drawing, and unrestricted scope involved in the present invention.
Referring to illustrated in figures 1 and 2; The present invention includes compacting platform 1, top box 2, template 4, raising middle flask 5 and venting mechanism 3, said venting mechanism 3 is fixed on the compacting platform 1 through fastener 9, and said template 4 is positioned at the below of said venting mechanism 3; Template 4 links together with raising middle flask 5; Said top box 2 is positioned at the top of raising middle flask 5, and top box 2 is fixed by said fastener 9, is provided with support 8 on the top of compacting platform 1; On said support 8, be provided with cylinder 7, an end and the said fastener 9 of the piston of said cylinder 7 link together; Said cylinder 7 can change oil cylinder into.Said compacting platform 1 is provided with control system 6, and said cylinder 7 links to each other with said control system 6 through holding wire.
Said venting mechanism 3 comprises loam cake 10, spacer 11, axle sleeve 12, spring 13 and air tube 14, and said axle sleeve 12 inside are provided with cavity, and loam cake 10 links together with spacer 11, is used for said spring 13 is fixed in the said cavity; The top of said air tube 14 is fixed together through fixture and said spring 13, and said venting mechanism 3 is connected with said compacting platform 1 through said axle sleeve 12.
During work, under the control of the control system 6 of compacting platform 1, cylinder 7 actions are because venting mechanism 3 links together with compacting platform 1; Template 4 links together with raising middle flask 5, during moulding, in top box 2 and raising middle flask 5 mould assembling modeling processes; Air tube 14 sees through molding sand and removes to contact template 4, and when touching template 4, spring 13 begins to shrink; Even venting mechanism 3 continues to move down, air tube 14 can not damage template 4 yet, and on template 4, has accomplished the operation of venting.
