Abstract

The utility model discloses a hot runner injection mold. The hot runner injection mold comprises an injector nozzle, a hot runner plate and a hot runner, wherein the hot runner is located in the hot runner plate; a female die is connected with the hot runner plate; pouring openings are formed in the female die; a male die is matched with the female die; the injection nozzle is connected with the inlet of the hot runner; the outlet of the hot runner is connected with the pouring openings. The hot runner injection mold is characterized in that two pouring openings are arranged; the inside of the hot runner plate is provided with a heater; the female die is provided with a location post; a groove matched with the location post is formed in the male die. The two pouring openings are formed in the female die, so that the working efficiency of the hot runner injection mold is doubled; in order to prevent the raw material from coagulating in the hot runner plate, an electric heater is additionally arranged, so that the molten state of plastics in the hot runner is ensured; the coagulation of the raw material on the surface of the hot runner is avoided; the injection pressure loss is small; the production cost is reduced.

Description

Hot runner injection mould
Technical field
The utility model belongs to processing mechanical apparatus field, relates in particular to a kind of hot runner injection mould.
Background technology
Hot flow path mold for injection molding, because its Hot runner Technology is a kind of advanced technology that is applied to plastic injection mold cast flow passage system, is a focus direction of injection molding technological development.So-called hot runner molding refers to the independent heating depending on hot flow path, the plastics that are sent to cast gate from nozzle of injector remain molten condition, when each die sinking, do not need to solidify as waste material and take out, the melt being trapped in running gate system can be injected into die cavity when injecting again.Hot flow path mold for injection molding has the products surface quality of improvement and mechanical property, hot flow path waste material, saves material, reduces costs, shortens molding cycle, improves machine efficiency, improves the plurality of advantages such as injection-molded item surface aesthetic degree.So hot flow path mold for injection molding has obtained more and more extensive use.But existing hot runner injection mould only arranges a cast gate, and operating efficiency is limited.The problem that while having in the closure of die and punch in addition, closure does not go up, closed precision is not high.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides a kind of hot runner injection mould, comprise nozzle of injector, hot runner manifold, hot flow path, die, punch and cast gate, described hot flow path is positioned at described hot runner manifold, described die is connected with described hot runner manifold, described cast gate is positioned on described die, described punch mates with described die, described nozzle of injector is connected with described hot flow path entrance, described hot flow path outlet is connected with described cast gate, the quantity that it is characterized in that described cast gate is two, in described hot runner manifold, be provided with heater, described die is provided with locating dowel, described punch is provided with the groove mating with described locating dowel.
Described heater is electric heater.
The beneficial effects of the utility model are: two cast gates are set on die, operating efficiency of the present utility model is doubled, for preventing that the solidifying material of raw material from having added electric heater in hot runner manifold, guaranteed plastics in hot flow path in molten condition, avoided the solidifying material in surface of raw material hot flow path, injection pressure loss is little, has lowered production cost; Locating dowel is set on die, the groove mating with described locating dowel is set on described punch, improved the closed precision of die and punch, improved operating efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
In figure, 1, nozzle of injector; 2, hot runner manifold; 3, hot flow path; 4, die; 5, punch; 6, cast gate; 7, heater; 8, locating dowel; 9, groove.
As shown in Figure 1, hot flow path 3 is positioned at hot runner manifold 2, and die 4 is connected with hot runner manifold 2, and cast gate 6 is positioned on die 4, punch 5 mates with die 4, nozzle of injector 1 is connected with hot flow path 3 entrances, and hot flow path 3 outlets are connected with cast gate 6, and the quantity of cast gate 6 is two, in hot runner manifold 2, be provided with heater 7, die 4 is provided with locating dowel 8, and punch 5 is provided with the groove 9 mating with locating dowel 8, and heater 7 is electric heater.
By embodiment, to of the present utility model, have been described in detail above, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variations of doing according to the utility model application range and improvement etc., within all should still belonging to patent covering scope of the present utility model.
