Abstract

The utility model provides a simple and easy stripper, it includes the base, fixes the setting support on the base, can set up with reciprocating stripper roof on the support is located stripper roof below just fixes cylinder on the base, a tip of cylinder has the telescopic piston rod, the stripper roof with the free end fixed connection of piston rod, be provided with on the upper surface of stripper roof and be used for the fixed quick change coupler who treats the ejector core mould. When the sand core in the core box needs to be ejected, the piston rod of the air cylinder moves upwards to enable the top plate of the stripper to move upwards, and the ascending motion of the top plate of the stripper pushes the outer ejector rod of the core box to move upwards at the same time, so that the purpose of ejecting the sand core in the core box is achieved. When the core box needs to work continuously to eject the sand cores in other core boxes, only the core box part on the support needs to be replaced, the core box is not required to be repeatedly disassembled and assembled with the cold core box core shooter, the purpose of quickly replacing the core box can be achieved, and the demolding efficiency is high.

Description

A kind of simple and easy ingot stripper

Technical field

The utility model relates to a kind of simple and easy ingot stripper.

Background technology

The cold-box sand core manufacturing craft is that the core box that will assemble connects with coremaking equipment, will inject in the core box die cavity with the mixed silica sand of resin, is blown into the triethylamine gas of heating again, makes core in the core box that the chemistry reflection take place and solidifies the back and form core, is used for casting pouring.

In the prior art, as shown in Figure 3, present core box is by upper plate 11, penetrate sand plate 20, last core box base plate 30, last core box 40, following core box 50 and following core box base plate 60 are formed, wherein upper plate 11, penetrating sand plate 20 is connected with core shooter, when changing whole pair of core box, needs then need to unclamp being connected between upper plate 11 and the core shooter, unclamp and penetrate being connected between sand plate 20 and the core shooter, unclamp being connected between core box base plate 30 and the last core box 40, unclamp down being connected of core box 50 and following core box base plate 60, and then the new core box of a pair is retightened on cold-box core blower.As run into the situation of a mould amphitypy, when needing to change a type wherein, need equally will be all connection adorn again again one time after removing.Therefore changing core box needs a large amount of duplication of labour, causes the significant wastage in manpower and man-hour, also greatly reduces production efficiency simultaneously.

The utility model content

The purpose of this utility model provides a kind of simple and easy ingot stripper that is exclusively used in the demoulding, and the core box of only changing on the support when changing core box partly gets final product, and need not repetition and cold-box core blower dismounting, can change core box apace.

The utility model can be implemented by the following technical programs: a kind of simple and easy ingot stripper; it comprises base, be fixedly installed on support on the described base, can be arranged on the ingot stripper top board on the described support up or down; be positioned at described ingot stripper top board below and be fixed on cylinder on the described base; one end of described cylinder has telescopic piston rod; the free end of described ingot stripper top board and described piston rod is fixedly connected, and the upper surface of described ingot stripper top board is provided with and is used for fixing the hydraulic quick coupler for the treatment of the plunger tip mould.

In a kind of technical scheme of optimization, described hydraulic quick coupler comprises and is T-shape connector and two buckles that are " n " type.

Compared with the prior art the utility model has following advantage:

The utility model is when using; when the core box on the support that is placed on ingot stripper is finished when needing plunger tip in coremaking; the bottom of core box also has inverted T-shape joint, with on the end that two buckles that are " n " type is buckled in after the T-shape joint of hydraulic quick coupler matches two T-shape joints with fastening core box and ingot stripper top board.When needs ejected the core of core box the inside, the piston rod of cylinder moved upward and makes the ingot stripper top board move upward, and the outer push rod that the ascending motion promotion core box of ingot stripper top board carries moves upward simultaneously, reaches the purpose that ejects the core in the core box.

When needs work on when ejecting core in other core boxes, a core box that only needs to change on the support partly gets final product, and need not repetition and cold-box core blower dismounting, can change core box apace.

The specific embodiment

As shown in Figure 1; a kind of simple and easy ingot stripper; it comprises base 1, be fixedly installed on support 2 on the described base 1, can be arranged on the ingot stripper top board 4 on the described support 2 up or down; be positioned at described ingot stripper top board 4 belows and be fixed on cylinder 3 on the described base 1; one end of described cylinder 3 has telescopic piston rod 5; described ingot stripper top board 4 is fixedly connected with the free end of described piston rod 5, and the upper surface of described ingot stripper top board 4 is provided with and is used for fixing the hydraulic quick coupler 6 for the treatment of the plunger tip mould.

Described hydraulic quick coupler 6 comprises and is T-shape connector 7 and two buckles 8 that are " n " type, is used for changing easily and fast the core box for the treatment of plunger tip.

When the core box on the support 2 that is placed on ingot stripper is finished when needing plunger tip in coremaking; because the bottom of core box 10 also has inverted T-shape joint; with two buckles that are " n " type are buckled on the end of two T-shape joints after the T-shape joint of hydraulic quick coupler matches, core box 10 and ingot stripper top board 4 are firmly fixed together.When ejecting the core of core box 10 the insides; the piston rod 5 of cylinder 3 moves upward and makes ingot stripper top board 4 move upward; the outer push rod 9 that the ascending motion promotion core box 10 of ingot stripper top board 4 carries moves upward simultaneously, reaches the purpose of the core that ejects 10 li of core boxes, and stable and reliable operation.

When needs work on when ejecting core in other core boxes 10, core box 10 parts that only need to change on the support 2 get final product, and need not repetition and cold-box core blower dismounting, then can reach the purpose of changing core box 10 apace.Can adopt screw to connect flat key location, dismounting simple and convenient being connected between core box 10 and the ingot stripper.

The utility model is simple in structure, and to compare manufacturing cost lower with large-scale demoulding equipment, can be widely used in The phenolic sand molding Simple demoulding does not need the demoulding of overturning. And the utility model is exclusively used in the stripping process, Do not need frequent the dismounting and being connected of core making machine equipment, core box replacing speed has been saved manpower and man-hour, Demoulding efficiency is higher.
