Description

The pneumatic fast demoulding molding core maker of a kind of tide mould sand

Technical field

The utility model relates to a kind of sand casting mo(u)lding equipment, the pneumatic fast demoulding molding core maker of especially a kind of tide mould sand.

Background technology

Tide mould sand is one of the simplest the most conventional sand casting molding and core making technique, the foundry goods of producing with tide mould sand, and production cost is low, any surface finish, corner angle are clear, percent defective is low, applied widely, production less investment; Original tide mould sand moulding and core manufacturing craft are a kind of strong physical works, are manual operations in modeling process substantially, complete on the ground modeling coremaking, in one day workman to repeatedly bend over for a long time, turnover mould, labour intensity is quite large, and meanwhile, operating efficiency is low; Again because the feature of tide mould sand is that sand mold intensity is low, resting period is short, technology and qualification to operator are had relatively high expectations, along with improving constantly of modern society's living standard, increasing people is unwilling to be engaged in the occupation that this labour intensity is large, technical requirement is high, many Foundry Works can not find the casting technique that such operator has to select other, and this selection will cause rising and the production equipment replacement investment of enterprise's production cost, reduced the competitive advantage of enterprise in market.

Summary of the invention

In order to reduce existing tide mould sand molding and core making, produce the dependence to operator, alleviate operator's labour intensity, reduce operator's technical ability requirement, improve production efficiency and product quality, the utility model provides a kind of tide mould sand pneumatic fast demoulding molding core maker, can effectively realize mechanization production, alleviate the labour intensity in molding and core making process, improve production efficiency and product quality.

The utility model solves the technical scheme that its technical problem adopts: the pneumatic fast demoulding molding core maker of a kind of tide mould sand, there is a mould and a molding flask, it is characterized in that: it also has a rectangle modeling platform, actuating cylinder, guide pillar, pneumatic control switch, Die and mould plate; There is a rectangular opening at the platform middle part of rectangle modeling platform, and the size of rectangular opening is identical with the profile of Die and mould plate, and is slidably matched with the profile of Die and mould plate; Actuating cylinder is arranged on the installing rack of rectangle modeling platform bottom, for Die and mould plate moves, provides power, and Die and mould plate is rectangle, be arranged on the top land of actuating cylinder, mould is positioned on Die and mould plate, and in the both sides of Die and mould plate, reverse side is provided with slide opening plate, and slide opening plate is provided with slide opening; Guide pillar is arranged between the platform and installing rack of rectangle modeling platform, and coordinates with the slide opening on slide plate, for moving up and down of Die and mould plate provides accurate location; Pneumatic control switch is located on the column outside of rectangle modeling platform, and is communicated with actuating cylinder and external compressed air by force pipe.

Accompanying drawing explanation

Fig. 1 is the pneumatic fast demoulding molding core maker of a kind of tide mould sand of the utility model structural representation.

In Fig. 1,1, mould, 2, molding flask, 3, banker, 4, pneumatic control switch, 5, actuating cylinder, 6, force pipe, 7, guide pillar, 8, Die and mould plate.

The specific embodiment

Below in conjunction with accompanying drawing 1, the pneumatic fast demoulding molding core maker of a kind of tide mould sand of the utility model is described further.

The pneumatic fast demoulding molding core maker of a kind of tide mould sand shown in Fig. 1, there is a mould 1 and a molding flask 2, molding flask 2 is detachable rectangular configuration, modeling platform 3 is rectangle steel, the platform of rectangle modeling platform 3 adopts more abundant steel plate to make, there is a rectangular opening at platform middle part, and rectangular opening size is identical with the profile of Die and mould plate 8, and is slidably matched with the profile of Die and mould plate 8; Actuating cylinder 5 is arranged on the installing rack of rectangle modeling platform 3 bottoms, for moving up and down, mould 1 provides power, Die and mould plate 8 is rectangle, its thickness is identical with the platform of rectangle banker 3, and be fixed on the top land of actuating cylinder 5, mould 1 is positioned on Die and mould plate 8, is provided with slide opening plate 9 below the both sides of Die and mould plate 8, and slide opening plate 9 is provided with slide opening; Guide pillar 7 is arranged between the platform and installing rack of rectangle banker 3, and coordinates with the slide opening on slide opening plate 9, for moving up and down of Die and mould plate 8 provides accurate location; Pneumatic control 4 switches are located on the column outside of rectangle banker 3, and are communicated with actuating cylinder 5 and external compressed air by force pipe 6.

Said actuating cylinder 5 can adopt gear mechanism or hydraulic system to replace as power source.

For the molding and core making of larger workpiece, for guaranteeing that mould 1 moves up and down smooth and easy and accurate positioning, can adopt 2 or 2 above actuating cylinders 5.

Operation principle: according to big or small design model platform 3 and the Die and mould plate 8 of mould 1, and mould 1 is arranged on Die and mould plate 8, compressed air is connected to actuating cylinder 5 by pneumatic control switch 4, open the up switch of pneumatic control switch 4, actuating cylinder 5 will be shifted molding and core making position onto on Die and mould plate 8 and mould 1, up switch is in closed condition, molding flask 2 is arranged on banker 3 platforms, tide mould sand consolidation molding and core making is put in beginning in molding flask 2, after completing, open the downing switch of pneumatic control switch 4, actuating cylinder 5 is descending, drive moves downward Die and mould plate 8 together with mould 1, stop motion while going downwards to certain position, the downing switch of pneumatic control switch 4 is in closed condition, actuating cylinder 5 is quit work, now mould 1 is separated stably smoothly under the drive of Die and mould plate 8 from tide mould sand type or core, complete smoothly molding work.Operator is transported to other place by tide mould sand sand mold or core from banker 3 and waits for next operation, next operator clears up banker 3 and mould 1, open the up switch of pneumatic control switch 4, actuating cylinder 5 will be shifted molding and core making position onto on Die and mould plate 8 and mould 1, enters next circulation.
