Abstract
The invention discloses a novel injection mould. The novel injection mould comprises a pouring system, a molding part and a hot and cold circulating device, wherein the hot and cold circulating device covers outside the pouring system and the molding part; the hot and cold circulating device is provided with a hot flow inlet and a cold flow inlet which are parallel to each other; the hot and cold circulating device is further provided with a temperature induction control system. With the adoption of the manner, the novel injection mould can overcome the disadvantages in the prior art, the surface texture and the glossiness of a product are improved, the visibility of a fusing trace is reduced and the precision of the product is improved; meanwhile, the internal stress of a plastic part is reduced and the service life of the product is prolonged.
Description
Technical field
The present invention relates to mould applications, particularly relate to a kind of injection mold.
Background technology
Along with national economic development and manufacturing high speed development, precision to the requirement of injection mold and plastic components is also more and more higher, traditional injection mold is because temperature is controlled the unreasonable incomplete or cooling insufficient problem of molten plastic of plastics melting that often exists, cause the plastic components of producing rough, precision is not high.Plastics melting simultaneously is incomplete, also can cause cooling waste material, has wasted raw material.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of novel injection mold, can overcome the deficiencies in the prior art, improves product surface quality and glossiness, reduce the visibility of weld mark, improve the precision of product, reduce the working of plastics internal stress simultaneously, extend product service life.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is:
A kind of Novel injection mold is provided, comprise: running gate system, profiled part and cold and heat circulating device, described cold and heat circulating device is wrapped in the outside of described running gate system and described profiled part, described cold and heat circulating device is provided with parallel hot-fluid entrance and cold flow entrance, also is provided with the temperature sense control system on described cold and heat circulating device.
In a preferred embodiment of the present invention, also be provided with the flow of the hot-fluid of controlling the described hot-fluid entrance of flowing through and the by-pass valve control of the flow of the cold flow of the described cold flow entrance of flowing through described in described Novel injection mold on cold and heat circulating device.
In a preferred embodiment of the present invention, described Novel injection mold, described hot-fluid is steam or superheated water, described cold flow is cold water.
The invention has the beneficial effects as follows: a kind of Novel injection mold of the present invention, be provided with cold and heat circulating device in the injection mold outside, cold and heat circulating device has the temperature sense control system, and design temperature changes running status as requested, in conjunction with valve, controls alternately entering of hot-fluid or cold flow, heating or cooling die, the articles injection-moulded smooth in appearance that adopts the present invention to produce, weld mark is few, and internal stress is low, long service life, and reduced material loss.
The accompanying drawing explanation
Fig. 1 is the structural representation of a preferred embodiment of the present invention;
In accompanying drawing, the mark of each parts is as follows: 1, running gate system, 2, profiled part, 3, cooling and heating circulation system, 4, the temperature sense system, 5, the hot-fluid entrance, 6, the cold flow entrance, 7, by-pass valve control.
The specific embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made to more explicit defining.
Refer to Fig. 1, the embodiment of the present invention comprises:
A kind of Novel injection mold, comprise running gate system 1, profiled part 2 and cold and heat circulating device 3, cold and heat circulating device 3 is wrapped in outside running gate system 1 and profiled part 2, change the running status of mould by temperature sense system 4, hot-fluid and cold flow are from outside input cold and heat circulating device 3, type of thermal communication superheat flow entrance 5 by-pass valve control 7 of flowing through enters cold and heat circulating device 3 and forms thermal cycles, and same cold flow enters cold and heat circulating device 3 and forms cold circulation from cold flow entrance 6 by-pass valve control 7 of flowing through.
At the injection moulding initial period, hot-fluid circulates, the heating mould surface.After reaching design temperature, the temperature sense control system starts, and makes the injection mold picked up signal, in plastic melt injection moulding parts.By-pass valve control 7 receives the signal that temperature sense system 4 is sent, and the logical hot-fluid of wheel stream translation or cold flow complete injection after being full of in mould, and cold flow enters mould immediately, makes the quick cooling and shaping of plastic components.After plastic components is cooling, to open mould and eject the plastic components of moulding, 4 conversion and control valves 7 of temperature sense system flow into hot-fluid and form thermal cycle, restart to be heated for mould.
This Novel injection mold provided by the invention can be used in the production of various product, and can effectively improve surface texturisation and the glossiness precision of plastic components, extends life of product, reduces material loss.
The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes specification of the present invention and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in scope of patent protection of the present invention.
