Abstract
The utility model discloses a 3-plate mold injection mold which comprises a stationary mold fixed plate, a stationary mold striper plate, a stationary mold plate, a dynamic mold plate, a dynamic mold support, a top plate and a stationary mold fixed plate; a stationary mold insert and a dynamic mold insert are respectively arranged on the stationary mold plate and the dynamic mold plate, the mold cores of the stationary mold insert and the dynamic mold insert are arranged in opposite to form a cavity, a hot nozzle is arranged on the front end of a runner of the stationary mold plate, a feeding bar is arranged in the hot nozzle and the rear part of the hot nozzle is provided with a hot nozzle press plate, a hot nozzle wiring device is also arranged on the stationary mold plate, and the hot nozzle is connected with a power supply through the hot nozzle wiring device. As the hot nozzle is arranged on the front end of the runner for reheating the plastic and performing injection, the problem that the finished product is difficult to be completely filled through injection as the 3-plate mold has a long runner, is easy to have temperature loss and has easily-cooled plastic; so the forming technicians can obtain better forming conditions for producing good products through injection, meanwhile the productivity is improved, and the material cost is greatly reduced as no runner plate is not needed.
Description
Technical field
The utility model relates to a kind of heater of injection mold, especially relates to a kind of heat hot mouth of runner front end setting of injection mold, belongs 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.
The utility model content
In order to overcome the deficiencies in the prior art, the purpose of this utility model be 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 utility model 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 beneficial effects of the utility model are: the utility model 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 utility model in detail:
Fig. 1 is the utility model one example structure schematic diagram.
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 utility model with preferred embodiment, so it is not in order to restriction the utility model, and all employings are equal to replaces or technical scheme that the equivalent transformation mode is obtained, all drops within the protection domain of the present utility model.
