Abstract

The invention relates to a core jig which is used for taking out a sand core from a core setting mould and feeding the sand core into a cavity on a pouring line, wherein the sand core comprises a sand core body; a positioning hole is formed at the top of the sand core body; multiple iron nails are inserted into the sand core body; the flat end of each iron nail is positioned at the upper part of the sand core body, and the sharp end of each iron nail penetrates through the lower part of the sand core body; the core jig comprises a frame, a fixing plate, a pushing plate, a driving mechanism and a locating pin; the fixing plate is connected to the frame; the pushing plate is positioned below the fixing plate and can slide up and down relative to the fixing plate; the driving mechanism drives the pushing plate to slide up and down relative to the fixing plate; the locating pin is arranged on the pushing plate and matched with the positioning hole; and the lower part of the pushing plate is provided with an electromagnetic attraction head which absorbs the sand core through the iron nails. The core jig provided by the invention can ensure that the sand core put in the cavity does not float upward without additionally using compaction stone for the sand core in the core setting process, is simple in structure and convenient to operate, and can be widely applied to the mechanical or automatic production line of batch production.

Description

Core jig

Technical field

The present invention relates to a kind of core jig.

Background technology

Core jig generally is used for core is clamped the back and shifts core down accurately.At present, the core jig of prior art mainly comprises hold assembly, is used for holder is shifted down the moving-member of core.When the operation core jig, hold assembly stretches to earlier in the core mold core is grasped, and core is in die cavity under through moving-member core being shifted then.But; Generally there is following defective in the core jig of this class formation: in following core process; When hold assembly when core is pulled out, core can come-up to a certain degree occur because receive the pulling force that hold assembly makes progress, this just need be with core through manual work or compress stone core is pressed in the die cavity; Complicated operation, inefficiency; Simultaneously, stressed improper when compressing core, can cause core broken, be that defectives such as drop, pore appear in foundry goods, deviation also appears in its precision easily.

Summary of the invention

The object of the invention provides the core jig that a kind of nothing compresses the stone sand core.

For achieving the above object, the technical scheme that the present invention adopts is:

A kind of core jig; Be used for core is taken out and send into the die cavity on the teeming line from following core mold; Described core comprises the core body; The top of described core body offers locating hole; Also be interspersed with many iron nails on the described core body, the flat end of described iron nail is positioned at described core upper part of body, and the sharp end of described iron nail passes the bottom of described core body; The alignment pin that described core jig comprises framework, be connected fixed head on the described framework, be positioned at described fixed head below and the push pedal that can described relatively fixed head slides up and down, drive driving mechanism that described push pedal slides up and down with respect to described fixed head, be arranged in the described push pedal and be complementary with described locating hole; The bottom of described push pedal is provided with the electromagnetic force suction nozzle, and when described electromagnetic force suction nozzle was switched on, described electromagnetic force suction nozzle picked up described core through described iron nail.

Preferably, described electromagnetic force suction nozzle number is identical with the number of described iron nail, and the position that is provided with of described electromagnetic force suction nozzle and described iron nail adapts.

Preferably, what the bottom of described push pedal was provided with hollow pushes away core stone, and described electromagnetic force suction nozzle is housed in the described inside that pushes away core stone.

Because technique scheme utilization, the present invention compared with prior art has advantage and effect: core jig of the present invention need not core used in addition to compress stone in core process down, just can guarantee rising phenomenon can not occur behind the die cavity that core puts into; And it is simple in structure, easy and simple to handle, can be widely used on the production line of mechanization or automation of batch process.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment the present invention is further described:

A kind of core jig 15 as shown in Figure 1, this core jig 15 are used for core is taken out and send into the die cavity 13 on the teeming line from following core mold 14.

Wherein: this core comprises core body 11; The top of core body 11 offers locating hole 12; Also be interspersed with many iron nails 10 on the core body 11, the flat end of iron nail 10 is positioned at the top of core body 11, and the sharp end of iron nail 10 passes the bottom of core body 11.

The alignment pin 5 that core jig 15 comprises framework 1, is connected fixed head 3 on the framework 1, is positioned at fixed head 3 belows and the push pedal 4 that can relative fixed plate 3 slides up and down, drives the driving mechanism 9 that push pedal 4 slides up and down with respect to fixed head 3 and be arranged in the push pedal 4 and be complementary with locating hole 12 through connector 2.

What the bottom of push pedal 4 was provided with hollow pushes away core stone 6; Push away core stone 6 inside and contain the electromagnetic force suction nozzle 7 that can adopt solenoid to process; The upper end of electromagnetic force suction nozzle 7 is connected on the fixed head 3 through a fixed bar 8; And the number of electromagnetic force suction nozzle 7 is identical with the number of iron nail 10, and electromagnetic force suction nozzle 7 adapts with the position that is provided with of iron nail 10.

Below the concrete method of operating of present embodiment down of setting forth:

Core jig 15 moves to down the top of core mold 14, and is as shown in Figure 2; Core jig 15 moves down, and alignment pin 5 is inserted in the locating hole 12 on the

core body

11, and 7 energisings of electromagnetic force suction nozzle hold the iron nail 10 that is arranged in the core body 11, and are as shown in Figure 3; Core jig 15 holds core body 11 and moves up, and move to die cavity 13 directly over, move down again, in die cavity 13, the iron nails 10 in the core body 11 are inserted in the die cavity 13 core body 11, as shown in Figure 4; 7 outages of electromagnetic force suction nozzle, driving mechanism 9 upwards draws framework 1, fixed head 3, push pedal 4 is pushed away downwards, compresses core body 11 downwards and push away core stone 6; As shown in Figure 5, after fixed head 3 and push pedal 4 were relatively moving to certain distance, promptly core body 11 consolidations was pressed in the die cavity 13; Core jig 15 moves on together, and alignment pin 5 breaks away from from locating

hole

12, and 11 of core bodies rest in the die cavity 13; As shown in Figure 6, core jig 15 constantly repeats above-mentioned action.

The foregoing description only is explanation technical conceive of the present invention and characteristics, and its purpose is to let the personage who is familiar with this technology can understand content of the present invention and enforcement according to this, can not limit protection scope of the present invention with this.All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed within protection scope of the present invention.
