Description
Technical field
The present invention relates to a kind of foundry machinery, and in particular to a kind of casting machine venting structure.
Background technology
In the production process of casting, if casting vertical direction size is larger, when cast, molten iron is difficult to discharge gas after flowing into peak, causes cast(ing) surface to have sand holes or the casting to have defect phenomenon.To avoid the generation of this phenomenon, typically after mould assembling, several cores are pricked on the sand mold of top box, play scavenging action.So, the operation of venting is indispensable operation during castings production.It is typically all that operating personnel take air tube dazzling by hand in China's venting, and method more advanced in the world is to prick exhaust eye with special venting machine.Either dazzling or machine is dazzling by hand, and core position is intended to be estimated by operating personnel, often causes core to bias, and is vented not smooth consequence.
The content of the invention
Instant invention overcomes the deficiencies in the prior art, it is proposed that a kind of casting machine venting structure, described device uses combined type venting device, is directly installed on the compacting table top of moulding machine, and one is realized with moulding machine；Using spring compression form, when vent wire touches template, spring-compressed, it is to avoid damage template；According to the shape of model on template, the position of venting device is determined, it is ensured that the accuracy of institute's venting position.
The technical scheme is that：A kind of casting machine venting structure, including compacting platform, top box, template, raising middle flask and venting mechanism, the venting mechanism is fixed on compacting platform by fastener, the template is located at the lower section of the venting mechanism, and template links together with raising middle flask, and the top box is located at the top of raising middle flask, top box is fixed by the fastener, support is provided with the top of compacting platform, cylinder is provided with the bracket, one end of the piston of the cylinder links together with the fastener；
The venting mechanism includes upper lid, spacer, axle sleeve, spring and air tube, and cavity is provided with inside the axle sleeve, and upper lid links together with spacer, for the spring to be fixed in the cavity；The top of the air tube is fixed together by fixing device with the spring, and the venting mechanism is connected by the axle sleeve with the compacting platform.
The compacting platform is provided with control system, and the cylinder is connected by holding wire with the control system.
The present invention has the advantages that：
1）Using combined type venting device, it is directly installed on the compacting table top of moulding machine, one is realized with moulding machine；
2）Using spring compression form, when vent wire touches template, spring-compressed, it is to avoid damage template；
3) according to the shape of model on template, the position of venting device is determined, it is ensured that the accuracy of institute's venting position;
4) present invention realizes the process of venting while upper and lower case mould assembling modeling process, eliminates single venting operation, saves the moulding time, improves productivity ratio;
5）Core position is accurate, the accurate venting in modeling process, the vapor and other gases of sand mold top layer generation can in time be excluded, metal liquid Fast Filling can be conducive to and mitigate arch action of the high temperature gas flow to sand mold top layer, be beneficial to be moved and reduction moisture condensation area moisture after making moisture condensation area.
Brief description of the drawings
The present invention is further illustrated below in conjunction with the drawings and specific embodiments.
Fig. 1 is structural representation of the invention.
Fig. 2 is venting mechanism structure schematic diagram of the invention.
In figure, 1, compacting platform；2nd, top box；3rd, venting mechanism；4th, template；5th, raising middle flask；6th, control system；7th, cylinder；8th, support；9th, fastener；10th, upper lid；11st, spacer；12nd, axle sleeve；13rd, spring；14th, air tube.
Specific embodiment
Further illustrated below in conjunction with accompanying drawing, not limit scope involved in the present invention.
Referring to shown in Fig. 1 and Fig. 2, the present invention includes compacting platform 1, top box 2, template 4, raising middle flask 5 and venting mechanism 3, the venting mechanism 3 is fixed on compacting platform 1 by fastener 9, the template 4 is located at the lower section of the venting mechanism 3, template 4 links together with raising middle flask 5, the top box 2 is located at the top of raising middle flask 5, top box 2 is fixed by the fastener 9, support 8 is provided with the top of compacting platform 1, cylinder 7 is provided with the support 8, one end of the piston of the cylinder 7 links together with the fastener 9；The cylinder 7 can change oil cylinder into.The compacting platform 1 is provided with control system 6, and the cylinder 7 is connected by holding wire with the control system 6.
The venting mechanism 3 includes upper lid 10, spacer 11, axle sleeve 12, spring 13 and air tube 14, and cavity is provided with inside the axle sleeve 12, and upper lid 10 links together with spacer 11, for the spring 13 to be fixed in the cavity；The top of the air tube 14 is fixed together by fixing device with the spring 13, and the venting mechanism 3 is connected by the axle sleeve 12 with the compacting platform 1.
During work, under the control of the control system 6 of compacting platform 1, cylinder 7 is acted, 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 the mould assembling modeling process of raising middle flask 5, air tube 14 goes to contact template 4 through molding sand, when template 4 is touched, spring 13 is started to shrink at, even if venting mechanism 3 continues to move down, air tube 14 will not also damage template 4, and the operation of venting is completed on template 4.
