Background technology
Reaction injection molding（Abbreviation RIM）, a kind of industrial contour machining procedure.Have the one of chemical reaction in forming process
Kind of injection moulding method, it is not polymer that this method is raw materials used, but by two or more liquid monomer or pre-polymerization
Thing, is added separately in mixing head with certain proportion, is well mixed under elevated pressure, is expelled in Guan Bi mould immediately, in mould
Polymerizing curable, is shaped into product.Due to it is raw materials used be liquid, die cavity can be rapidly filled with smaller pressure, so reducing
Mold clamping force and mould cost, are particularly well-suited to produce large area product.
RIM is only used for polyurethane material earliest, and with the progress of technology, RIM can also be applied to multiple material（Such as ring
Oxygen, nylon, polyureas and dicyclopentadiene etc.）Processing.It is the heat of current research for rubber and the RIM techniques of metal forming
Point.
Reaction injection molding each component one is blended, immediately fast reaction, and material can penetrate core-pulling mechanism and mould
In the gap of tool, influence is brought on core pulling and product quality after solidification.Existing core-pulling mechanism is applied to reaction injection molding mould
Tool, not only easily causes overlap to product, influences yield rate, and easily forms clamping stagnation, influences core pulling effect.
The content of the invention
In order to overcome the defect of prior art, the present invention provides one kind and is difficult clamping stagnation, easy to maintenance for reaction injection
The core-pulling mechanism of mould.
In order to solve the above-mentioned technical problem, the present invention provides a kind of core-pulling mechanism for reaction injection molding mould, bag
Include the first fixed plate being connected with die；The first fixed block being connected with the two ends of first fixed plate respectively and second is fixed
Block；Two ends respectively with first fixed block and second fixed plate being connected away from the first fixed plate end of the second fixed block；With
The core that the cavity that first fixed plate, the first fixed block, the second fixed plate, the second fixed block are surrounded is slidably connected；At least
Two are connected with first fixed plate and the second fixed plate, for the guide runner that the core is slided；It is connected with the core, is driven
Hydraulic jack or cylinder that the dynamic core is slided；It is arranged on the core and the first fixed plate, the first fixed block, the second fixation
Seal groove on plate, the contact surface of the second fixed block；Sealing ring in the insertion seal groove；It is connected with the die, is ensured
The alignment pin that the core can be accurately positioned during matched moulds.
As further improved technology scheme, provided by the present invention for the core-pulling mechanism of reaction injection molding mould, also
With the wearing plate being embedded on the sliding surface that the core is contacted with cavity.
As further improved technology scheme, provided by the present invention for the core-pulling mechanism of reaction injection molding mould, institute
State on the cylinder seat connection one of which guide runner of hydraulic jack or cylinder, the piston rod and institute of the hydraulic jack or cylinder
State core connection.
In the case where not conflicting, above-mentioned improvement project can be implemented alone or in combination.
The technical scheme that the present invention is provided, core is provided with sealing ring, when injecting reaction solution after matched moulds, can prevent reaction solution
Into in the gap between core and cavity, clamping stagnation during so as to avoiding core pulling from operating influences core pulling effect；First fixed plate,
One fixed block, the second fixed plate, the second fixed block connect into the cavity slided for core, and with easy to maintenance, maintenance cost is low
The characteristics of；In improvement project, wearing plate is inlaid with core, the service life of core can be extended.
Brief description of the drawings
Accompanying drawing is used for providing a further understanding of the present invention, constitutes the part of the application, schematic reality of the invention
