Specific embodiment
It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, it is not intended to limit the present invention.
Referring to figure 2. to Fig. 4, tunnel loose core mechanism of the present invention preferred embodiment include tunnel briquetting 10, tunnel mold insert 20,
Type core 30 and core_pulling pole, the core_pulling pole are sheathed in the tunnel that the tunnel briquetting 10 is formed with the type core 30, and can
It is moved along the tunnel, wherein the core_pulling pole successively includes the guide section matched with the tunnel briquetting 10 from outside to inside
40, the cross section of the sealing section 50 and core pulling section 60 matched with the type core 30, the guide section 40 and sealing section 50 is equal
For circle, the cross section of the core pulling section 60 is compatible rectangular with extraneous 70 core pulling hole shape of product.
Wherein, the guide section 40 is sheathed in the tunnel that the tunnel briquetting 10 is formed with the type core 30, and can edge
The tunnel movement.
The diameter of the guide section 40 is greater than the diameter of the sealing section 50, and the diameter of the sealing section 50 is greater than the pumping
The maximum width of core section 60.
One end that the sealing section 50 is connect with the guide section 40 is provided with step, is provided with arc on the step and falls
Angle.
The structural principle of the tunnel loose core mechanism proposed below to the present embodiment elaborates:
The tunnel loose core mechanism that the present embodiment proposes is made of tunnel briquetting 10, core_pulling pole, tunnel mold insert 20, and core_pulling pole is logical
The movement of the tunnel in type core 30 and tunnel briquetting 10 is crossed, wherein core_pulling pole is improved to three-stage, and one section cooperates with tunnel briquetting 10
As guide section 40, two sections are used as sealing section 50 with the cooperation of type core 30, and three sections are core pulling section 60.
Core pulling section 60 is independent to be used as third section, so that guide section 40 and sealing section 50 is no longer limited to core pulling hole location shape and must
It must be designed as rectangular, guide section 40 and sealing section 50 are changed to cylinder, and processing technology is simple, reduce process time and cost,
And the one end of sealing section 50 connecting with the guide section 40 is provided with step, design has arc angling (technique circle at step
Angle R), proof strength, production loss less, reduce spare parts demand to greatest extent.
Design has tunnel briquetting 10 at 40 cooperation of guide section, makes to be screwed, formation combined type tunnel, easy disassembly,
Bedding-in and maintenance.
50 conic projection area of sealing section is greater than 60 square hole of core pulling section, and the region beyond square hole boundary is to set change to reserve,
According to practical set experience, long side a of the conic projection diameter D generally than square hole projection exceeds 2mm, needs to adjust buckle
Only need to boss be freezed or be discharged when elastic, if becoming scope control within cylinder, not will lead to tunnel, core_pulling pole etc.
Mechanism is scrapped, if becoming, risk is small, the period is short, at low cost.
The beneficial effect of tunnel loose core mechanism of the present invention is:
A. structure is simple: tunnel loose core mechanism proposed by the present invention is made of tunnel briquetting, core_pulling pole and tunnel mold insert,
Not complicated movement mechanism；
B. easy to process: building block is all the square and bar of simple shape, and core_pulling pole purchased parts, which are simply restructured, is
Can, since the cooperation precision in bar and hole is easier to realize, tunnel processing only needs depth drill, cuts processing without accurate time-consuming line；
C. dismounting, easy maintenance: using combined type tunnel, removes tunnel briquetting, that is, replaceable and maintenance core_pulling pole；
D. high-efficient: structure is simple, and processing technology simplifies, dismounting, easy maintenance, and bedding-in workload when parts replacement
It is small, it is high-efficient；
E. the safety is improved: core_pulling pole is changed to three-stage, and design is cylindrical and technique fillet ensure that intensity, substantially reduces
The risk of fatigue damage；
F. manufacturing cost is low: core pulling tunnel sections cooperation precision is easily guaranteed that, cuts processing without line, and core_pulling pole can be voluntarily
Buying restructuring, spare parts demand amount reduce, and manufacturing cost reduces；
G. it sets and becomes at low cost: setting change and be controlled within cylinder, core pulling boss need to be only modified, not will lead to tunnel
Mechanism is scrapped, and flexibly, if becoming, risk is small, the period is short, at low cost for change；
H. performance is stablized: dismounting easy maintenance can be inspected periodically and be lubricated, and core_pulling pole intensity is high, and structural stability is high.
The above is only a preferred embodiment of the present invention, is not intended to limit the scope of the invention, all to utilize this hair
Equivalent structure or equivalent flow shift made by bright specification and accompanying drawing content is applied directly or indirectly in other relevant skills
Art field, is included within the scope of the present invention.
