Abstract
The present invention discloses a kind of hydraulic pressure ejecting structure of plastic mould, and the structure includes：Oil hydraulic cylinder, on the support block of the plastic mould；Oil circuit, connected in the support block, and with the oil hydraulic cylinder；Connecting rod, its one end and the telescopic end of the oil hydraulic cylinder are fixed, and the liftout plate of the other end and the plastic mould is fixed.Compared to prior art, the hydraulic pressure ejecting structure of plastic mould of the invention, due to being that oil circuit is arranged in the support block of plastic mould, oil pipe is damaged by pressure in die-filling, form removal and transportation so as to avoid；Oil pipe reduces space, and will not interfere with the other structures on the outside of mould in support block；It is longer than using the service life of oil pipe；Oil hydraulic cylinder, which installs rear subsequent maintenance form removal and is not required to tear oil hydraulic cylinder open, is not present Leakage.
Description
【Technical field】
The present invention relates to a kind of hydraulic pressure ejecting structure, and in particular to a kind of hydraulic pressure ejecting structure of plastic mould.
【Background technology】
Male model pours in down a chimney designed into glue for plastic mould in commonly use mould structure, and male model pour in down a chimney into glue mould substantially
All ejected using hydraulic pressure (oil hydraulic cylinder).
Fig. 1 is please referred to, the visual angle of hydraulic pressure ejecting structure first that Fig. 1 is schematically shown as a kind of plastic mould of prior art is cutd open
View, Fig. 2 are schematically shown as a kind of the second visual angle of hydraulic pressure ejecting structure sectional view of plastic mould of prior art.
As illustrated, the hydraulic pressure ejecting structure includes oil hydraulic cylinder 101, oil gathering block 102, oil connection 103,104 groups of oil pipe
Into.Using the structure, have as a drawback that：1st, because the oil pipe 104 is located at the outside of the plastic mould, in die-filling, form removal
With easily oil pipe is damaged by pressure in transportation；2nd, oil pipe 104 is easily interfered with the other structures on the outside of mould；3rd, oil pipe 104 is easy
Aging service life is short；4th, mould can all have substantial amounts of oil leak to scene after oil pipe 104 is removed in maintenance, influence environmental sanitation.
In view of this, it is necessary to develop a kind of hydraulic pressure ejecting structure of plastic mould in fact, to solve the above problems.
【The content of the invention】
It is therefore an object of the present invention to provide a kind of hydraulic pressure ejecting structure of plastic mould, solves existing hydraulic pressure ejection knot
Structure is short using service life, the problem of easily damaging by pressure and interfere with plastic mould other structures.
In order to achieve the above object, the hydraulic pressure ejecting structure of plastic mould of the invention, the structure include：
Oil hydraulic cylinder, on the support block of the plastic mould；
Oil circuit, connected in the support block, and with the oil hydraulic cylinder；
Connecting rod, its one end and the telescopic end of the oil hydraulic cylinder are fixed, and the liftout plate of the other end and the plastic mould is fixed.
Optionally, the oil circuit is set up in the support block internal drilling.
Optionally, the connecting rod has orthogonal connecting portion.
Compared to prior art, the hydraulic pressure ejecting structure of plastic mould of the invention, due to being that oil circuit is arranged at into plastic cement
In the support block of mould, oil pipe is damaged by pressure in die-filling, form removal and transportation so as to avoid；Oil pipe reduces in support block
Space, and will not interfere with the other structures on the outside of mould；It is longer than using the service life of oil pipe；Oil hydraulic cylinder is follow-up after installing
Maintenance form removal, which is not required to tear oil hydraulic cylinder open, is not present Leakage.
【Brief description of the drawings】
Fig. 1 is schematically shown as a kind of the first visual angle of hydraulic pressure ejecting structure sectional view of plastic mould of prior art.
Fig. 2 is schematically shown as a kind of the second visual angle of hydraulic pressure ejecting structure sectional view of plastic mould of prior art.
Fig. 3 is schematically shown as the first visual angle of hydraulic pressure ejecting structure sectional view of the plastic mould of the present invention.
Fig. 4 is schematically shown as the second visual angle of hydraulic pressure ejecting structure sectional view of the plastic mould of the present invention.
【Embodiment】
Fig. 3, Fig. 4 are please referred to, Fig. 3 is schematically shown as the first visual angle of hydraulic pressure ejecting structure section view of the plastic mould of the present invention
Figure, Fig. 4 are schematically shown as the second visual angle of hydraulic pressure ejecting structure sectional view of the plastic mould of the present invention.
In order to achieve the above object, the hydraulic pressure ejecting structure of plastic mould of the invention, the structure include：
Oil hydraulic cylinder 201, on the support block 202 of the plastic mould；
Oil circuit 203, connected in the support block 202, and with the oil hydraulic cylinder 201；
Connecting rod 204, its one end and the telescopic end of the oil hydraulic cylinder 201 are fixed, the ejection of the other end and the plastic mould
Plate 205 is fixed.
Wherein, the oil circuit 203 is set up in the internal drilling of support block 202.
Wherein, the connecting rod 204 has orthogonal connecting portion, solid with the oil hydraulic cylinder 201 and liftout plate 205 respectively
It is fixed.
Compared to prior art, the hydraulic pressure ejecting structure of plastic mould of the invention, due to being that oil circuit 203 is arranged at into modeling
In the support block 202 of sealing rubber die, oil pipe is damaged by pressure in die-filling, form removal and transportation so as to avoid；Oil pipe is located at support block 202
It is interior, reduce space, and will not interfere with the other structures on the outside of mould；It is longer than using the service life of oil pipe；Oil hydraulic cylinder 201
Install rear subsequent maintenance form removal and be not required to tear oil hydraulic cylinder 201 open and Leakage is not present.
It is noted that the invention is not restricted to above-mentioned embodiment, any person skilled in the art is based on this hair
Any simple modification, equivalent change and modification that bright technical scheme is made to above-described embodiment, both fall within the protection model of the present invention
In enclosing.
