Description
Technical field
The present invention relates to polyurethane foam plastics technical field, be specifically related to a kind of manufacture method of polyurethane foam hollow ball.
Background technology
Existing polyurethane (PU) spheroid general following methods manufacture of foaming forms (as shown in Figure 1): the inner mould with the die cavity of predetermined sphere shape of preparation, then release agent spraying on mould, and then spray paint in mould, the urethane raw for foaming is poured in mould, matched moulds, shake mould and carry out foamable reaction, to make the foam filled whole die cavity of urethane raw, after die sinking, namely take out product.But manufacture polyurethane foam spheroid by the method and have urethane raw consumption greatly, production cost is high, and the shortcoming that the finished product spheroid obtained is heavier.
Publication number is CN1365882A publication date is on August 28th, 2002, the Chinese invention patent application that denomination of invention is " method of forming of foamed toy body " discloses a kind of method of forming of foamed toy body, it passes through following steps: the existing ethene-vinyl acetate copolymer base material of the one step foaming of looking ahead, through cutting into the toy body base material that several sections have predetermined amount, make toy body base material put into mould inside and carry out two degree of foaming, cool to suppress substrate surface to foam rapidly to mould afterwards after a predetermined time to grow up, thus obtain interior layer expansion, the toy structure of the smooth densification of superficial layer.Although the method for forming of this foamed toy body can reduce the raw-material consumption of foaming, the shaping of a toy body needs through second time of foaming, and whole manufacture process is easy not, also needs to control in time, and this kind of production method does not reduce human cost.
One had both saved foaming raw material usage, low production cost, can overcome again the heavier shortcoming of foaming spheroid itself, and manufacture process is simple, the manufacture method that is easy to the foamed hollow spheroid of control, does not also have report at present.
Summary of the invention
The manufacture method the present invention is directed to the deficiencies in the prior art, provide that a kind of urethane raw consumption is little, production cost is low and finished product spheroid is comparatively light, manufacture process is simple, being easy to the polyurethane foam hollow ball controlled.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions:
A manufacture method for polyurethane foam hollow ball, is characterized in that, comprises following step:
(1) foaming molding mold is opened, at mould inner surface spraying releasing agent;
(2) place several movable blocks at mould inner surface, an inflatable bladder is put into the position that mould is limited by several movable blocks described;
(3) urethane raw is injected in foaming molding mold;
(4) matched moulds and polymerisation;
(5) die sinking obtains product;
(6) take out described inflatable bladder and described movable block, get product.
Further, several movable blocks described are detachable is spaced reciprocally fixed on described mould inner surface.
Further, movable block is cylinder, and described mould inner surface is fixed in described cylinder bottom surface.
Further, also foaming molding mold is vacuumized between described (4) step and (5) step.
Further, also following steps are carried out between described (1) step and (2) step: spray in mould to the mould inner surface scribbling releasing agent and paint.
Particularly, described urethane raw comprises PPG, isocyanates and amines catalyst/organic tin catalyst.
Further, described inflatable bladder is rubber ball.
The invention provides a kind of finished product obtained by the manufacture method of described polyurethane foam hollow ball.
The manufacture method of polyurethane foam hollow ball of the present invention, its beneficial effect is:
(1) adopt the manufacture method of polyurethane foam hollow ball of the present invention, foaming urethane raw consumption greatly reduces, and greatly can reduce production cost;
(2) by hollow ball that the manufacture method of polyurethane foam hollow ball of the present invention is obtained, lighter in weight, and the size of product hollowness is adjustable, can requires to select different inflatable bladder and movable block according to the difference of hollow ball, produce different hollow balls thus;
(3) manufacture method of polyurethane foam hollow ball of the present invention, manufacture process is simple, is easy to operate and control.
