Abstract
The invention discloses a plastic mold. The plastic mold comprises a mold cavity and a convex mold insert which are matched with each other, a pipeline is tightly attached to the joint of the mold cavity and the convex mold insert, and a plurality of electric heaters are evenly distributed in the pipeline. The pipeline is in an inverted-U shape and filled with heat conduction media. The electric heaters are oval, so that the contact area between the electric heaters and water inside the pipeline is maximized, and heating is accelerated advantageously. During use, water in the pipeline is heated through the electric heaters and becomes hot, the overall heat transfer is faster through the heat conduction media, heat is transferred to the mold cavity through the pipeline to be heated, and plastic materials in the mold cavity are molten and further cooled, cured and formed. The plastic mold is novel and ingenious in structural design, uniform in heating and high in heating speed, the working efficiency is remarkably improved, and the quality of produced plastic products is ensured.
Description
[technical field]
The present invention relates to machine die technical field, be used for, particularly to one, the plastics system that produces
The mould of plastics of product.
[background technology]
For thermosetting plastics, such as solid silicone rubber or liquid thermosetting plastics, use it
When producing plastic product, need to put between mold cavity and punch, to plastics by plastic material
Material carries out heating makes it melt, and the melt in die cavity is through pressurize, cooling, solidifying and setting shape
Become plastic product.The mode such as the PULSE HEATING generally by soldering tip or heated at constant temperature that heats heats
Solid silicone rubber or fluent material are to molten state, and PULSE HEATING costly, and heats uneven,
Heated at constant temperature is relatively slow, need to consume the long period.
[summary of the invention]
In view of this, for overcoming the deficiencies in the prior art, the present invention provides a kind of mould of plastics,
Heating is more uniformly distributed, and firing rate is faster, easy to use, economical and practical.
For achieving the above object, technical scheme is as follows:
A kind of mould of plastics, including suitable mold cavity and punch insert, at described mould
Die cavity closely posts pipeline with the joining place of punch insert, is uniformly distributed multiple electricity in described pipeline
Heater.
Further, described pipeline is form of an inverted " u ", and the inside arranges heat-conducting medium.
Described electric heater oval in shape so that it is maximum with the current contact area in pipeline
Change, be conducive to heating faster.
During use, placing water and heated by electric heater in described pipeline, current heating is also
Made its overall heat transfer faster by described heat-conducting medium, transfer heat to described mould by pipeline
It is heated by die cavity, melts its interior plastic material, further cools and solidifies sizing, complete
Mold pressing process.
The invention has the beneficial effects as follows, novel in structural design, easy to use, heat mould speed
Faster, heating.
[accompanying drawing explanation]
In order to be illustrated more clearly that the embodiment of the present invention or technical scheme of the prior art, under
The accompanying drawing used required in embodiment or description of the prior art will be briefly described by face,
It should be evident that the accompanying drawing in describing below is only some embodiments of the present invention, for
From the point of view of those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to
Other accompanying drawing is obtained according to these accompanying drawings.
Fig. 1 is the structural representation of the present invention.
In figure, 1, mold cavity, 2, punch insert, 3, pipeline, 4, electric heater, 5,
Current.
[detailed description of the invention]
Below in conjunction with the accompanying drawing in the embodiment of the present invention, to the technology in the embodiment of the present invention
Scheme is clearly and completely described, it is clear that described embodiment is only the present invention
A part of embodiment rather than whole embodiments.Based on the embodiment in the present invention, this
It is every other that field those of ordinary skill is obtained under not making creative work premise
Embodiment, broadly falls into the scope of protection of the invention.
With reference to Fig. 1, a kind of mould of plastics for heating, including suitable mold cavity 1
With punch insert 2, the joining place at described mold cavity 1 with punch insert 2 closely posts pipe
Road 3, is uniformly distributed multiple oval electric heater 4 in described pipeline 3.
Pipeline 3 is in form of an inverted " u ", and the inside arranges heat-conducting medium, be covered with mold cavity 1 with
The junction of punch insert 2, it is simple to mold cavity 1 entirety is evenly heated.
Electric heater 4 oval in shape so that it is maximize with the current contact area in pipeline 3,
Be conducive to heating faster.
During use, placing water and heated by electric heater 4 in described pipeline 3, current become
Heat is also made its overall heat transfer faster by described heat-conducting medium, transfers heat to institute by pipeline 3
Stating mold cavity 1 to heat it, melt its interior plastic material, further cooling and solidifying is fixed
Type, completes mold pressing process.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention,
All within the spirit and principles in the present invention, any modification, equivalent substitution and improvement etc. made,
Should be included within the scope of the present invention.
