Abstract
The utility model relates to an exhaust structure of reaction injection forming mould, excessive gas -reservoir material piece including the activity, the gas -reservoir material piece that overflows is inside or the outside is equipped with the cavity and have open end to link to each other with it, the gas -reservoir material piece that overflows sets up in the tired gas position of the part that takes shape, and the part is stranded the open end UNICOM of gas position and excessive gas -reservoir material, the utility model discloses a be stranded the gas position at the part and set up the gas -reservoir material piece that overflows, solved the problem that formed part is not enough of being stranded gas and arousing in forming process.
Description
Technical field
The utility model relates to a kind of exhaust structure of mould, particularly relates to a kind of exhaust structure of reaction injection molding mould.
Background technology
The injection forming process that reaction injection molding technique is different with common, the problem often can encountered in forming process is that formation of parts is stranded gas, the exhaust solution of existing injection molded is not suitable for reaction injection molding mould completely, in industry solution is preferentially stranded the increase of gas position as the gas-guiding structure of muscle one class at part at present, but, the change of formation of parts structure is not allowed in most instances, can only be solved by adjustment die angle or injection speed, if said method can not thoroughly be dealt with problems, can only solve by carrying out filling and repairing after shaping, therefore, tired gas is a difficult problem of restriction the sector development, effective especially solution is there is no at present in industry.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of exhaust structure of reaction injection molding mould, solves the exhausting problem that formation of parts is stranded gas position.
The utility model solves the technical scheme that its technical problem adopts: provide a kind of reaction injection molding die venting structure, comprise excessive gas-reservoir materials and parts, and the inner or outside of described excessive gas-reservoir materials and parts is provided with the open port that cavity is connected with cavity with at least one.
Described excessive gas-reservoir material exhaust part can take off from mould actively, and described excessive gas-reservoir materials and parts use to be made by the material of attraction, and described excessive gas-reservoir materials and parts can be the combinations of a part or multiple part.
Beneficial effect
Owing to have employed above-mentioned technical scheme, the utility model compared with prior art, there is following advantage and good effect: the utility model arranges excessive gas-reservoir materials and parts by being stranded gas position at part, solve the exhaust at tired gas position in part forming process and cause scarce material problem, improve the quality of formation of parts.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with specific embodiment, further elaboration the utility model, should understand, these embodiments are only not used in restriction scope of the present utility model for illustration of the utility model, in addition should understand, after the content of having read the utility model instruction, those skilled in the art can make various changes or modifications the utility model, and these equivalent form of values fall within the application's appended claims limited range equally.
As shown in Figure 1, embodiment of the present utility model relates to a kind of die venting structure, comprises excessive gas-reservoir materials and parts 1, and the inside of the gas-reservoir materials and parts 1 that overflow is processed with cone space and 2 open ports be attached thereto, the material of excessive gas-reservoir materials and parts 1 is steel, can by the adhesive of magnetic material institute.Before matched moulds, excessive gas-reservoir materials and parts 1 are put into mould assigned address, the locking of part is ensured by magnetic force, injection material enters die cavity, and the tired gas produced at the boss place of formation of parts 2 and part clout are extruded in the interior tapered space of excessive gas-reservoir materials and parts 1, during the demoulding, the gas-reservoir materials and parts 1 that overflow are separated from die cavity with formation of parts 2, excessive gas-reservoir materials and parts 1 are separated with formation of parts 2, the residue in the cavity of excessive gas-reservoir materials and parts 1 are cleared up, again recycles.
Claims (2)
1. an exhaust structure for reaction injection molding mould, comprises excessive gas-reservoir materials and parts, it is characterized in that the open port that the inside of excessive gas-reservoir materials and parts or outside are provided with cavity and are connected with cavity with at least one.
2. the exhaust structure of a kind of reaction injection molding mould according to claim 1, is characterized in that, described excessive gas-reservoir materials and parts can take off from mould actively, and described excessive gas-reservoir materials and parts use the magnetic steel of tool to make.
