The utility model is characterized in that a supporting bracket ring is arranged on the upright column, a rotation arm is sleeved on the upright column, a fixing pressing ring is arranged above the rotation arm, a trans-position handle is arranged on the rotation arm, a master cylinder is arranged under the rotation arm, the lower part of the master cylinder is connected with the supporting bracket ring, the piston rod under the master cylinder is fixed through connection with a compacting flat plate through a connecting element, vibrators are symmetrically arranged on the compacting flat plate, an air valve is arranged on the rotation arm, and an air inlet Q of the air valve is connected with the compressed air source; the machine applies to the cast of small castings, relieves the labor intensity, increases the working efficiency more than two times, and greatly improves the casting quality.

Description

Portable microseism squeeze moulding machine

(1) technical field:

The utility model relates to a kind of casting and molding equipment.

(2) background technology:

Before the utility model was made, China's casting small size foundry goods generally adopted hand moulding, dashed the real sand mold of pounding with sand, and it is big to exist labour intensity, inefficiency, shortcomings such as molding quality difference.

(3) technology contents:

Problem to be solved in the utility model provides and a kind ofly reduces labour intensity, increases work efficiency and the portable microseism squeeze moulding machine of molding quality, is applicable to that the casting small size foundry goods uses.

The technical scheme that the utility model solves is, structure such as Fig. 1 of this movable type microseism squeeze moulding machine, Fig. 2, Fig. 3, shown in Figure 4, it comprises base plate, workbench, compress flat board, vibrator, master cylinder, column, parts such as bracing frame ring and pivoted arm: wherein set of wheels 1 is equipped with at base plate 2 two ends, column 15 is housed on base plate 2, workbench 4 is installed on the base plate 2 by adjusting bolt 17, workbench 4 is welded with side dog screw 3 and main dog screw 16, the location that is used for sandbox 5, column 15 is set with bracing frame ring 14, supporting locating ring 12 is welded on the column 15, column 15 is set with pivoted arm 10, fixedly trim ring 11 is housed above, locating piece 13 is housed on the pivoted arm 10 is used for the duty location, transposition handle 20 is housed above the pivoted arm 10, master cylinder 9 is equipped with in pivoted arm 10 belows, master cylinder 9 bottoms are connected with bracing frame ring 14, form strong fix, master cylinder 9 following piston rods 21 are connected and fixed with compressing flat board 6 by connector 8, compress dull and stereotyped 6 and are symmetrically installed with vibrator 7; Air valve 19 is installed on the pivoted arm 10, and the air inlet Q of air valve 19 is connected with compressed air gas source, and interface a ' is connected with a of master cylinder 9, and interface b ' is connected with master cylinder 9 interface b, and interface c ' is connected with the c interface of vibrator 7; It includes housing 7-3 this vibrator 7, and piston 7-4 is equipped with in the inside, and piston 7-4 right-hand member has compression spring 7-5, and two ends are equipped with plug 7-1,7-7 and sealing ring 7-2,7-6 respectively, and piston 7-4 has internal channel f and circular passage e, air inlet c and exhaust outlet d.

The utility model has the following advantages compared with the prior art:

1, owing to adopt machinery that sand mold is carried out the microseism compacting, finishes the labour intensity that ramming work alleviates the foundry worker greatly, can reduce this station labor grade requirement simultaneously;

2, adopt mechanical sand mold to carry out the microseism compacting, can increase work efficiency more than 2 times;

3, adopt mechanical vibrator that sand mold is carried out the microseism compacting, even because of its microseism compaction force, all can meet the demands to the hardness of the degree of packing of molding sand, sandstone and gas permeability etc., thereby improve casting quality greatly.

(5) specific embodiment

Below in conjunction with description of drawings the utility model operating principle.

During work sandbox 5 is placed on the workbench 4, move transposition handle 20, pivoted arm 10 is moved on to the operating position, move on the position that switch knob 18 to ON opens, compressed air enters the interface of master cylinder 9a and the air inlet c of vibrator 7 through the interface of air valve 19a ', c ', compress dull and stereotyped 6 downlink working, the high-frequency vibration of vibrator 7 advances sand mold microseism compacting in the sandbox 5 simultaneously, finishes ramming work; On the position that rotating switch handle 18 to OFF closes, compressed air enters the interface of master cylinder 9b through the interface of air valve 19b ', and workbench 6 is up, and vibrator 7 stops vibrations, master cylinder 9 exhausts suitable for reading; Move transposition handle 20 once more, pivoted arm 10 is moved on to the location to be processed, change sandbox and proceed molding modeling operation once more.
