Description
Technical field
The present invention relates to ejection technique field, the method specificallying relate to demoulding polyurethane semi-finished product material and the device used.
Background technology
Present polyurethane is without mould turning class seal, and general is all first use casting mold, moulding by casting semi-finished product, then is finished product seal by semi-finished product turning.In the process that semi-finished product are shaping, semi-finished product can be close to external mold, cling bed die because semi-finished product shaping after have a certain amount of contraction, and there is extraordinary elasticity, so very tight that semi-finished product can be embraced with internal mold.
Current release method is: 1. manually first firmly knocked out by bed die with hammer; 2., by hydraulic press, by fixture (fixture does not have versatility, and every mold will have supporting fixture), then internal mold is taken off; 3. take off external mold again, obtain semi-finished product.Knock out bed die with hammer, this operational hazards, labor intensive is large, and is easy to damage bed die, also likely damages product; By hydraulic press, and 2-3 part fixture to be needed, such operation also danger close during de-internal mold, and make fixture and can increase cost.
Along with developing rapidly of hydraulic-pneumatic industry, hydraulic-pneumatic have also been obtained in other industry and applies widely, picture coal mine machinery, engineering machinery etc., these industries are all using polyurethane sealing ring in a large number, because polyurethane sealing ring specification is many, and belong to wearing detail, thus market for polyurethane without the demand of mould turning class seal also in steady increase.When producing polyurethane semi-finished product material in batches, present release method, expending for manpower, the speed of burn failure, makes the cost of fixture all by increase at double.
Summary of the invention
The object of the invention is to: the method providing the demoulding, its processing ease, labour intensity is low.
The present invention also aims to provide a kind of stripper apparatus, its cost is low, easily realizes scale and uses.
The present invention for solving the problems of the technologies described above adopted technical scheme is:
A kind of demoulding polyurethane semi-finished product material method, it is characterized in that, it comprises the following steps:
(1) arrange a fixed mould device, this fixed mould device comprises pin and lower stop lever, and described upper pin cover blocks the top of mould external mold, and described lower stop lever cover blocks the bottom of mould external mold, this lower stop lever fixed mould bed die; Described upper pin and lower stop lever and plane-parallel; Described upper pin and lower stop lever orthogonal, restriction mould external mold movement up and down;
(2) connection fastener be connected with power source is set, this connection fastener one end is fastened on mould inner mould, one end is connected with power source, starts power source and connection fastener can be made to pull mould inner mould to move up or move along inner mold center axis;
(3) fixed mould, power-on, drives connection fastener pull mould inner mould to move up or move along inner mold center axis, is slowly pulled out by internal mold, until mould inner mould and polyurethane semi-finished product material depart from completely;
(4) take a vertical level away from the pulling force in mould direction at mould external mold away from one end of bed die, mould external mold and bed die are departed from, it is inner that polyurethane semi-finished product material stays mould external mold;
(5) semi-finished product are slowly pulled out (carrying out mould) external mold, complete the demoulding;
(6) mould and stripper apparatus are assembled, carry out the cast operation of a new round.
Realize a device for above-mentioned demoulding polyurethane semi-finished product material method, it comprises a mainframe, connection fastener, a power source, fixed mould device; Described connection fastener one end is fastened on the internal mold of mould, and it is connected with described power source; This power source is arranged on above mainframe; Described fixed mould device comprises pin and lower stop lever, and this upper and lower pin cover blocks mould.
Described upper pin and lower stop lever and plane-parallel.
Described upper pin and lower stop lever orthogonal.
The shape of described upper pin is corresponding to the external mold upper end shape of mould, can block mould external mold by mosaic set.
The shape of described lower stop lever is corresponding to the external mold lower end shape of mould, can be stuck in around mould external mold by mosaic set, the motion in restriction mould left-right and front-back direction.
Described lower stop lever is arranged on above mold bottom die, and restriction bed die moves upward.
Invention beneficial effect
This release method that the present invention adopts and device, handling safety, simply, the labour intensity of workman is little, and cost is low, and production efficiency is high, can be satisfied with medium format and large gauge polyurethane semi-finished product material, the needs of in enormous quantities and a small amount of production demoulding.
(1) the present invention reduces production cost, improves production security.The present invention adopts and is first fixed together with external mold by bed die, to not fixture be re-used like this, below avoiding, prop up mould with fixture, manually with hand steered firmly external mold, press down with fixture the danger that the demoulding operates like this above again, avoid the high cost making fixture and cause.
(2) release method of the present invention, extends the mold use life-span, saves human resources, enhances productivity.The present invention adopts the method for directly first de-internal mold, avoids and first will knock out bed die with hammer, the damage of the bed die caused, avoid and expend too much manpower.
(3) release method of the present invention is simple to operate, reduces labour intensity.The present invention adopts special fixture, reduces the height of Mould operation, improves safe operation, avoids to move mould and expend too much manpower.
Below in conjunction with embodiment, the present invention is further described.
