Abstract
The invention relates to the technical field of injection molds, in particular to an injection mold suitable for molding of thermosetting plastic. The injection mold is provided with a fixed mold seat plate. A main runner bush is arranged at the middle position of the fixed mold plate. A main runner is formed in the main runner bush. Multiple layers of warm runner plates are arranged on the lower surface of the fixed mold seat plate and are internally and commonly provided with branch runners connected with the main runner. A female mold plate is arranged on the lower surface of the warm runner plate located on the lowermost layer, and a movable mold plate is arranged on the lower surface of the female mold plate. The main runner bush is evenly provided with a plurality of main runner cooling water holes. Each layer of warm runner plate is evenly provided with a plurality of branch runner cooling water holes. By means of the injection mold, the plastic cannot be cured and can have the proper viscosity, and thus the smooth conduction of injection molding is ensured.
Description
Technical field
The present invention relates to the technical field of injection mold, especially a kind of injection mold being applicable to thermoset plastic forming.
Background technology
Injection mold is the instrument producing plasthetics, and the material melted that is heated is injected die cavity by high pressure by it, after cooling curing, obtains formed products.Can soften flowing during thermosetting plastics first time heating, be heated to uniform temperature, produce chemical reaction one cross-linking reaction and cure hard, this change is irreversible, after this, when again heating, can not deliquescing flow again.Carry out processing and forming by this characteristic just, utilize plasticizing flowing during first time heating, be full of die cavity under stress, and then be solidified into the goods determining shape and size.But existing most injection mold comes with some shortcomings part in structural design, cause thermosetting plastics just to produce solidification phenomenon in flow passage system, cause injection mo(u)lding not go on smoothly, and waste a large amount of thermosetting plastics raw materials.
Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of injection mold being applicable to thermoset plastic forming, overcomes existing injection mold has just produced solidification phenomenon in flow passage system defect when using thermoset plastic forming.
The technical solution adopted for the present invention to solve the technical problems is: a kind of injection mold being applicable to thermoset plastic forming, there is top clamping plate, the middle position of described top clamping plate is provided with sprue bush, sprue is offered in described sprue bush, the lower surface of top clamping plate is provided with multilayer warm runner plate, the runner be connected mutually with sprue is jointly offered in described multilayer warm runner plate, the lower surface being positioned at undermost warm runner plate is provided with concave template, and the lower surface of described concave template is provided with moving platen; Described sprue bush evenly offers several sprue cooling water holes, every layer of warm runner plate all evenly offers several runner cooling water holes.
Further restriction, the concave template described in technique scheme and moving platen evenly offers several and is positioned at heater mounting hole around plastic product forming chamber.
Further restriction, the upper surface of the top clamping plate described in technique scheme is provided with cover half heat-insulating shield, and described is provided with warm mould thermal insulation board between undermost warm runner plate and concave template, and the lower surface of described moving platen is provided with dynamic model heat-insulating shield.
The invention has the beneficial effects as follows: the injection mold being applicable to thermoset plastic forming of the present invention, by setting up warm flow passage system, make thermosetting plastics continuously shaped operation in runner, remain melt-flow state and do not solidify, do not produce running gate system waste material, save raw material, plastics not only can not solidify, and there is suitable viscosity, ensure injection moldingly to carry out smoothly.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present invention.
In figure: 1, top clamping plate, 2, sprue bush, 3, sprue, 4, warm runner plate, 5, runner, 6, concave template, 7, moving platen, 8, sprue cooling water hole, 9, runner cooling water hole, 10, heater mounting hole, 11, cover half heat-insulating shield, 12, warm mould thermal insulation board, 13, dynamic model heat-insulating shield.
Detailed description of the invention
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present invention are described in a schematic way, and therefore it only shows the formation relevant with the present invention.
The present invention is as shown in Figure 1 applicable to the injection mold of thermoset plastic forming, there is top clamping plate 1, the middle position of described top clamping plate 1 is provided with sprue bush 2, sprue 3 is offered in described sprue bush 2, the lower surface of top clamping plate 1 is provided with multilayer warm runner plate 4, the runner 5 be connected mutually with sprue 3 is jointly offered in described multilayer warm runner plate 4, the lower surface being positioned at undermost warm runner plate 4 is provided with concave template 6, and the lower surface of described concave template 6 is provided with moving platen 7; Described sprue bush 2 evenly offers several sprue cooling water holes 8, every layer of warm runner plate 4 all evenly offers several runner cooling water holes 9.
Wherein, described concave template 6 and moving platen 7 evenly offer several and be positioned at heater mounting hole 10 around plastic product forming chamber.The upper surface of described top clamping plate 1 is provided with cover half heat-insulating shield 11, and described is provided with warm mould thermal insulation board 12 between undermost warm runner plate 4 and concave template 6, and the lower surface of described moving platen 7 is provided with dynamic model heat-insulating shield 13.
By setting up warm flow passage system in this injection mold, make thermosetting plastics continuously shaped operation in runner, remain melt-flow state and do not solidify, do not produce running gate system waste material, save raw material, plastics not only can not solidify, and have suitable viscosity, ensure injection moldingly to carry out smoothly.
With above-mentioned according to desirable embodiment of the present invention for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this invention technological thought, can carry out various change and amendment completely.The technical scope of this invention is not limited to the content on description, must determine its technical scope according to right.
