Abstract
The invention discloses a three-plate mold injection mold, which comprises a fixed-mold fixing plate, a fixed-mold stripping plate, a fixed mold plate, a movable mold plate, a movable mold foot, a top plate and a movable-mold fixing plate, wherein the fixed mold plate and the movable mold plate are provided with a fixed mold insert and a movable mold insert respectively; mold cores on the fixed mold insert and the movable mold insert correspond to each other to form a mold cavity; a hot nozzle is arranged at the front end of a channel on the fixed mold plate; a feeding framework is arranged in the hot nozzle; a hot nozzle pressing plate is arranged at the back part of the hot nozzle; a hot nozzle wiring device is also arranged on the fixed mold plate; and the hot nozzle is connected with a power supply through the hot nozzle wiring device. By arranging the hot nozzle at the front end of the channel to inject plastics by heating the plastics for a second time, the three-plate mold injection mold solves the problem that products are difficult to fill completely because of long channel of a three-plate mold, easy temperature loss and easy cooling of the plastics, gives large space to technicians in a shaping condition area for injecting high-quality products, improves production efficiency, and also greatly reduces material cost because of no need of a hot channel plate.
Description
Technical field
The present invention relates to a kind of heater of injection mold, especially relate to a kind of heat hot mouth of runner front end setting of injection mold, belong to the technology of die manufacturing field.
Background technology
At present, many plastic products all are that the mode by injection mo(u)lding processes, some goods make the very difficult filling of goods penetrate full because of the flowability of plastics itself, the embedding structure of goods, the factors such as thickness of goods glue position in injection moulding process, operating personnel are in order to overcome these problems normal condition of molding that only changes, for example, high speed and high pressure injection moulding, dwell time prolongation, raising mould temperature, this kind mode has influenced the quality of goods, burr, sticking to mould, stress, buckling deformation etc. occur as goods.
Summary of the invention
In order to overcome the deficiencies in the prior art, the object of the present invention is to provide a kind of simple in structure, can change the flowability of improving plastics well, make product molding be easy to three-plate mold injection mold.
The present invention is achieved through the following technical solutions:
A kind of three-plate mold injection mold, comprise the cover half fixed head, cover half stripper plate, solid plate, moving platen, dynamic model mould pin, top board and cover half fixed head, wherein, on solid plate and moving platen, be respectively arranged with cover half Renhe mavable module core, the corresponding mutually die cavity that forms of core on the mavable module core of cover half Renhe, it is characterized in that, the front end of the runner on solid plate is provided with hot mouth, be provided with the charging bone in the hot mouth, its rear portion then is provided with hot mouth pressing plate, also is provided with hot mouth termination on solid plate simultaneously, and hot mouth is connected with power supply by hot mouth termination.
Above-mentioned cover half fixed head is provided with and draws the material pin, draws the material pin to be connected with charging bone in the hot mouth with runner simultaneously.
Further, also be provided with the filling mouth on the above-mentioned cover half fixed head, irritate the mouth mouth and communicate with runner.
The invention has the beneficial effects as follows: the present invention carries out injection moulding by the mode that hot mouth is set at the runner front end plastics are heated once more, three template dies have been solved because of runner is long, temperature is easily lost, plastics easily are cooled to and make goods be difficult to fill the full problem of penetrating, make the goods that the forming technique personnel have very big space to inject in the condition of molding zone, also improved simultaneously production efficiency, because do not need hot runner manifold, so the material cost that yet greatly reduces.

The specific embodiment
Below in conjunction with accompanying drawing, describe the specific embodiment of the present invention in detail:
Fig. 1 is one embodiment of the invention structural representation.
As shown in Figure 1: three-plate mold injection mold, comprise cover half fixed head 1, cover half stripper plate 2, solid plate 3, moving platen 4, dynamic model mould pin 5, top board 6 and cover half fixed head 7, wherein, on solid plate 3 and moving platen 4, be respectively arranged with cover half benevolence 9 and mavable module core 8, the corresponding mutually die cavity that forms of core on cover half benevolence 9 and the mavable module core 8, and the front end of the runner on solid plate 3 is provided with hot mouth 10, be provided with the charging bone in the hot mouth 10, its rear portion then is provided with hot mouth pressing plate 11, be used for fixing hot mouth 10, also be provided with hot mouth termination simultaneously on solid plate 3, hot mouth 10 is connected with power supply by hot mouth termination.
Cover half fixed head 1 is provided with and draws material pin 12, draws material pin 12 to be connected with charging bone in the hot mouth 10 with runner simultaneously, irritates mouth 13 and also be provided with on the cover half fixed head 1, and the mouth of irritating mouth 13 communicates with runner.
Its operation principle is as follows:
In the process of injection moulding, by filling mouth 13 chargings that are arranged on the cover half fixed head 1, plastics directly flow to hot mouth 10 along runner, after hot mouth is heated, flow to die cavity then, be injection molded into goods, after injection moulding was finished, in the process of die sinking, the drawing material pin 12 that is installed on the cover half fixed head 1 was held charging bone and runner in the hot mouth 10, push by cover half stripper plate 2, finish an injection moulding program.
In the present embodiment, hot mouth 10 does not need hot runner manifold control, has saved material cost, at runner front end heating of plastic, has increased the flowability of plastics by hot mouth 10, makes its rapid directive die cavity, makes injection moulding effective.
Below disclose the present invention with preferred embodiment, so it is not in order to restriction the present invention, and all employings are equal to replaces or technical scheme that the equivalent transformation mode is obtained, all drops within protection scope of the present invention.
