Casting mould support frame

Technical Field

The utility model belongs to the technical field of the casting mould appurtenance, in particular to casting mould support frame.

Background

In casting production, casting molds need to be prepared in advance, the placement of the casting molds cannot meet the requirement of positive placement due to site limitation, the casting molds need to be laterally placed for production, and the casting molds with certain structures deform to different degrees due to the aging strength of the casting molds changing along with time and temperature.

The casting produced after the deformed casting mold is cast is unqualified, thereby causing waste.

Disclosure of Invention

The utility model aims at overcoming the above-mentioned shortcoming of prior art, provide a casting mould support frame, support the die cavity of the casting mould of putting to the side, reduce the deformation of casting mould.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

a casting mold support frame comprises a telescopic rod and support plates which are positioned at two ends of the telescopic rod and used for supporting the inner wall of a cavity; the telescopic rod comprises a sleeve, telescopic pipes positioned at two ends of the sleeve, nuts positioned on the sleeve and bolts in threaded connection with the nuts; the support plates are connected to the corresponding telescopic pipes, one ends of the telescopic pipes, far away from the corresponding support plates, are inserted into the corresponding ends of the sleeves, and the end parts of the bolts abut against the telescopic pipes. The support plate is supported on the inner wall of the cavity to slow down the deformation of the mold.

Preferably, the bolt is an M12 bolt. The M12 bolt is a common gauge, easy to produce.

Preferably, the thickness of the sleeve is 5 mm. The strength is higher.

Preferably, the bellows has a thickness of 5 mm. The strength is higher.

Preferably, the outer diameter of the sleeve is 60 mm. The outer diameter of the sleeve is large, and the sleeve is not easy to bend.

Preferably, one end of the extension tube, which is far away from the corresponding support plate, is provided with a piston, the sleeve is provided with an air tube used for being connected with the air pump, and the sleeve is provided with a pressure limiting valve used for controlling the air pressure in the sleeve. When the casting mold is supported, the air pump runs, the telescopic pipe extends, the supporting plate is automatically pressed on the inner wall of the casting mold, and meanwhile, in order to prevent the supporting plate from being too high in pressure, the pressure limiting valve is arranged, so that the pressure of the supporting plate can be effectively controlled, and the inner wall of the casting mold is effectively protected.

Preferably, the pressure limiting valve comprises a cylinder body with one end connected to the sleeve, an air outlet hole formed in the sleeve, a blocking block arranged in the cylinder body and used for blocking the air outlet hole, a spring used for pressing the blocking block on the air outlet hole, and a second air outlet hole formed in the cylinder body. When the pressure in the sleeve is overlarge, the spring contracts, and the blocking block is separated from the air outlet.

The utility model has the advantages that: the utility model provides a casting mould support frame supports the die cavity of the casting mould of putting to the offside, reduces the deformation of casting mould.

FIG. 2 is a cross-sectional view A-A of FIG. 1;

fig. 3 is a cross-sectional view of the present invention;

fig. 4 is an enlarged view of fig. 3 at B.

In the figure: the telescopic rod 1, the cavity 2, the supporting plate 3, the sleeve 4, the telescopic pipe 5, the nut 6, the bolt 7, the piston 8, the air pipe 9, the cylinder body 10, the air outlet hole 11, the blocking block 12, the spring 13 and the second air outlet hole 14.

Detailed Description

The invention will be further explained in detail with reference to the drawings and the following detailed description:

example (b):

referring to fig. 1 to 4, a casting mold support frame comprises a telescopic rod 1 and support plates 3 which are positioned at two ends of the telescopic rod 1 and are used for supporting the inner wall of a cavity 2;

the telescopic rod 1 comprises a sleeve 4, telescopic pipes 5 positioned at two ends of the sleeve 4, a nut 6 positioned on the sleeve 4 and a bolt 7 in threaded connection with the nut 6;

the support plate 3 is connected to the corresponding extension tube 5, one end of the extension tube 5, which is far away from the corresponding support plate 3, is inserted into the corresponding end of the sleeve 4, and the end part of the bolt 7 abuts against the extension tube 5.

Bolt 7 is an M12 bolt. The thickness of the sleeve 4 is 5 mm. The thickness of the bellows 5 is 5 mm. The outer diameter of the sleeve 4 is 60 mm.

A piston 8 is arranged at one end of the extension tube 5 far away from the corresponding support plate 3, an air tube 9 used for being connected with an air pump is arranged on the sleeve 4, and a pressure limiting valve used for controlling the air pressure in the sleeve 4 is arranged on the sleeve 4.

The pressure limiting valve comprises a cylinder body 10 with one end connected to the sleeve 4, an air outlet 11 positioned on the sleeve 4, a blocking block 12 positioned in the cylinder body 10 and used for blocking the air outlet 11, a spring 13 used for pressing the blocking block 12 on the air outlet 11, and a second air outlet 14 positioned on the cylinder body 10.

Principle of embodiment:

the air pump operation, telescopic link 1 extension, then backup pad 3 supports and leans on the inner wall of die cavity, then rotates bolt 7 to fixed with the length of telescopic link 1, after the casting mould side is put, support the inner wall that has a better support to the die cavity, thereby slow down the deformation of casting mould.

When the air pump runs, the air pressure of the sleeve 4 can be increased, and in order to prevent the pressure of the supporting plate to the cavity from being too high, a pressure limiting valve is arranged.

The working principle of the pressure limiting valve is that when the air pressure in the sleeve 4 is too high, the spring 13 is shortened, at the moment, the blocking block 12 is separated from the air outlet hole 11, and the air in the sleeve 4 is discharged from the air outlet hole 11.
