Abstract
The invention belongs to the technical field of dies and particularly relates to a plastic die with an automatic waste cutoff function. The plastic die comprises a female die body, a male die body, an injection molding pipeline arranged in the female die body, a cutter arranged on the male die body and an oil cylinder for driving the cutter to move. The cutter corresponds to an output opening of the injection molding pipeline in position. According to the plastic die with the automatic waste cutoff function, the cutter is arranged on the male die body, waste on plastic products can be cut off automatically when the dies are opened, the number of machining steps are reduced, and the working efficiency is improved.
Description
Technical field
The invention belongs to technical field of mold, particularly relate to a kind of mould of plastics having and automatically excising waste material function.
Background technology
Mould is used to the instrument of formed article, and this instrument is made up of various parts, and different moulds is by different zero
Part is constituted, and it mainly realizes the processing of article profile by the change of moulding material physical state.
Along with the fast development of plastics industry, plastic is used in life, the every field produced, and injection mo(u)lding is
A kind of processing method used when producing some complex-shaped parts in batches, during injection, clamping mould, on injection machine, will be heated
The material melted is injected in shaping mold cavity by high pressure, cools down molding at intracavity, and then upper and lower mould is separately, will system via ejection system
Product eject from die cavity and leave mould, and last mould is closed again and is molded next time, and the circulation of whole injection moulding process is carried out.
After plastic product forming, often leave waste material at the joint with injection molded tube, by it when needing following process
Excision or reparation, comparatively laborious.
Because above-mentioned defect, the design people, the most in addition research and innovation, to founding one, to have excision automatically useless
The mould of plastics of material function so that it is have more the value in industry.
Summary of the invention
For solving above-mentioned technical problem, it is an object of the invention to provide a kind of plastics mould having and automatically excising waste material function
Tool, it is possible to die sinking when, automatically excises waste material, decreases procedure of processing, improve work efficiency.
A kind of mould of plastics with excision waste material function automatically that the present invention proposes, including die, punch, is arranged on institute
State the injection molded tube in die, the cutter being arranged on described punch, drive the oil cylinder of described tool motion, the position of described cutter
Put the delivery outlet of corresponding described injection molded tube.
Further, described die is provided with pressure transducer.
Further, described pressure transducer is connected with described oil cylinder.
Further, it is provided with water annulus in described die and punch.
Further, described water annulus is externally provided with sealing ring.
Further, the material of described cutter is rustless steel.
By such scheme, the present invention at least has the advantage that the present invention to pass through on punch and arranges cutter, it is possible to
The when of die sinking, automatically the waste material on plastic is excised, decrease procedure of processing, improve work efficiency.
Described above is only the general introduction of technical solution of the present invention, in order to better understand the technological means of the present invention,
And can be practiced according to the content of description, below with presently preferred embodiments of the present invention and coordinate accompanying drawing describe in detail as after.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, the detailed description of the invention of the present invention is described in further detail.Hereinafter implement
Example is used for illustrating the present invention, but is not limited to the scope of the present invention.
See Fig. 1, a kind of mould of plastics with excision waste material function automatically described in a preferred embodiment of the present invention, bag
Include die 1, punch 2, the injection molded tube 3 being arranged in die 1, the cutter 4 being arranged on punch 2, the oil of driving cutter 4 motion
Cylinder 5, the delivery outlet of the position correspondence injection molded tube 3 of cutter 4.
Die 1 is provided with pressure transducer, and pressure transducer is connected with oil cylinder 5, and when die sinking, pressure transducer is experienced
The change of pressure, transmits a signal to oil cylinder 5, thus oil cylinder 5 drives cutter 4 to move downward, and is excised by waste material.Die 1 and convex
It is provided with water annulus 6 in mould 2, is used for cooling down workpiece.Water annulus 6 is externally provided with sealing ring.The material of cutter 4 is rustless steel.
In sum, the present invention is by arranging cutter 4 on punch 2, it is possible to die sinking when, automatically by plastic
On waste material excision, decrease procedure of processing, improve work efficiency.
The above is only the preferred embodiment of the present invention, is not limited to the present invention, it is noted that for this skill
For the those of ordinary skill in art field, on the premise of without departing from the technology of the present invention principle, it is also possible to make some improvement and
Modification, these improve and modification also should be regarded as protection scope of the present invention.
