Description
Technical field
The utility model is related to mold injection field, refers in particular to hole-cutting device in a kind of mould.
Background technology
At present, directly by hole injection moulding when the surface of many products is provided with hole position feature, such as fruit product injection moulding,
Then glue stream is combined in Kong Chu and can produce weld bond, influences product appearance；If not directly by hole injection moulding, formed product
After need by artificial removal, so as to increased labour intensity, reduce production efficiency.
As disclosed a kind of mould inside hole-cutting device and mould, including mould in prior art 201520696977.1
Plate and inner membrance, are provided with the cutter mechanism of converted products forming hole in the inner membrance, the template is provided with the power of cutter mechanism
Mechanism；Although after formed product can directly mould inside cut off sizing material, converted products forming hole, cutter mechanism is by cutting
Knife, the first backing plate and the second backing plate composition, assembling is inconvenient, and less stable.
Utility model content
The utility model purpose is to provide hole-cutting device in a kind of mould to overcome the deficiencies in the prior art, by adopting
With the cutting knife of monolithic construction, sizing material converted products forming hole directly can be removed in mould inscribe, it is ensured that the outward appearance of product is good, and
It is easy to assembly, good stability.
To reach above-mentioned purpose, the technical solution adopted in the utility model is：Hole-cutting device in a kind of mould, comprising template
And die, the cutting knife of converted products forming hole is provided with the die, it is provided with the template and drives the dynamic of cutting knife motion
Force mechanisms；The section Cheng " Shang of the cutting knife " fonts, the upper end end of wherein cutting knife is provided with the edge of a knife for being cut into type hole, and lower end sets
Spacing tool rest is equipped with, and the edge of a knife and spacing tool rest are monolithic construction.
Preferably, be provided with the cutting knife be fixed in template and with the guide rod of cutting knife coaxial line；In the guide rod also
It is provided with the thimble of ejection waste material.
Preferably, the both sides of the spacing tool rest are provided with back-moving spring in die.
Preferably, the actuating unit is drive cylinder or drives oil cylinder.
Due to the utilization of above-mentioned technical proposal, the utility model has following advantages compared with prior art：
Hole-cutting device, can directly in mould by the cutting knife using monolithic construction in mould described in the utility model
Excision sizing material converted products forming hole, it is ensured that the outward appearance of product is good, and easy to assembly, good stability.
Brief description of the drawings
Technical solutions of the utility model are described further below in conjunction with the accompanying drawings：
Accompanying drawing 1 is the structural representation of hole-cutting device in mould described in the utility model.
Wherein：1st, template；2nd, actuating unit；3rd, die；4th, cutting knife；41st, the edge of a knife；42nd, spacing tool rest；5th, guide rod；6th, it is multiple
Position spring；7th, thimble.
Specific embodiment
Below in conjunction with the accompanying drawings and specific embodiment the utility model is described in further detail.
Accompanying drawing 1 is hole-cutting device in mould described in the utility model, comprising template 1 and die 3, is set in the die 3
The cutting knife 4 of converted products forming hole is equipped with, the actuating unit 2 for driving the motion of cutting knife 4 is provided with the template 1；The cutting knife 4
Section be in " Shang " font, the upper end end of wherein cutting knife 4 is provided with the edge of a knife 41 for being cut into type hole, and lower end is provided with spacing tool rest
42, and the edge of a knife 41 and spacing tool rest 42 are monolithic construction, it is not only easy to assembly, and good stability when being cut into type hole；It is described to cut
Be additionally provided with knife 4 be fixed in template 1 and with the guide rod 5 of the coaxial line of cutting knife 4；Knife of the upper end of the guide rod 5 higher than cutting knife 4
Mouth 41, will not produce weld bond, and facilitate cutting knife 4 to cut off sizing material, converted products forming hole at hole during product injection moulding；Institute
State and thimble 7 is provided with guide rod 5, the thimble 7 passes through outside ejecting mechanism and drives, the waste material for ejecting excision so that produce
Product waste material is removed easy；The both sides of the spacing tool rest 42 are provided with back-moving spring 6 in die 3, are cut into after the completion of type hole
Enable the Rapid reset of cutting knife 4；The actuating unit 2 is two drive cylinders or drives oil cylinder.
When using：After the completion of product injection, actuating unit 2 promotes cutting knife 4 to be moved to shaped article direction, to realize producing
The processing of product forming hole, and cutting knife 4 is in movement, the forced compression of back-moving spring 6, treats that formed product hole machined is completed, cutting knife 4 exists
Rapid reset under the elastic force of back-moving spring 6.
Due to the utilization of above-mentioned technical proposal, the utility model has following advantages compared with prior art：
Hole-cutting device, can directly in mould by the cutting knife using monolithic construction in mould described in the utility model
Excision sizing material converted products forming hole, it is ensured that the outward appearance of product is good, and easy to assembly, good stability.
The above is only concrete application example of the present utility model, any limit is not constituted to protection domain of the present utility model
System.All use equivalents or equivalence replacement and the technical scheme that is formed, all fall within the utility model rights protection scope it
It is interior.
