Abstract
The utility model relates to a mold for manufacturing plastic foam, which comprises a mold inner sleeve and a mold outer sleeve; a flexible mold is positioned on the upper part, and a fixed mold is positioned on the lower part; particularly, the upper part of the flexible mold is connected with a volume weight controller. The utility model provides a mold which reduces the marginal effect and eliminates the phenomenon of the upper top arc; the manufactured plastic foam has great molding; the utility model can achieve cuboid products with arbitrary sizes without cutting or finishing, is suitable for irregular-type products with special exteriors, and is suitable for all amino resin manufacturing plastic foam, particularly the foaming process of melamine formaldehyde resin and phenolic resin.
Description
Technical field
The utility model relates to a kind of mould that utilizes amino resins to make foamed plastics, and particularly a kind of amino resins that utilizes that has the unit weight controller is made the mould of foamed plastics.
Background technology
The amino resins foaming is at first to produce expansion type amino resins, then through Over emulsfication emulsifying agent, blowing agent, curing agent, blowing promotor, filler etc., a series of raw material mixes and is placed in the mould, through the foamable curing molding, make foam article, its series of process is quite complicated.This just requires product unit weight even, the productive rate height, and cutting output is little.These control methods concentrate on the selection of mould, and mould is the important instrument that amino resins is made foamed plastics, also is the core instrument.
The amino resins foaming is a foam process of amino resins being placed one step foaming moulding in the mould, its moulding quality depends primarily on the reasonability of mould design, present foaming mould moulding also is mature on the whole, but the product boundary effect of producing is big, have a series of problems such as inhomogeneous, the last top of unit weight camber is big, and then the needs of product arrangement cutting output is big, the shortcoming that productive rate is low.
The utility model content
The amino resins that utilizes that the purpose of this utility model is to provide is made the mould of foamed plastics, produces that boundary effect is little, the foamed plastics of the forming that need not to cut arrangement.
To achieve these goals, the mould of manufacturing foamed plastics of the present utility model comprises cover and die coat in the mould, is positioned at the flexible mould that is of top, is positioned at the fixed mould that is of below, and described flexible mould top is connected with the unit weight controller.
As a kind of embodiment of the present utility model, flexible mould is a die coat, and described fixed mould is a cover in the mould, and described unit weight controller is fixed on the movement velocity of the connecting rod control die coat of die coat outer casing top surface center by it.The both sides of die coat are provided with guiding mechanism, put in the described fixing mould and are provided with hermetically-sealed construction.Described guiding mechanism comprises the fixing guide post that is arranged on the die coat both sides and be fixed on the fairlead that can slide on the two sides of die coat on guide post.
As another embodiment of the present utility model, described flexible mould is a cover in the mould, and described fixed mould is a die coat, and the unit weight controller is fixed on the middle part of flexible mould top by connecting rod, puts in the mould of described activity and is provided with top pressure closure.
Advantage of the present utility model is: by in the die coat of activity or mould, put be provided with the unit weight controller control unit weight evenly, make mould dwindle boundary effect greatly, do not have the phenomenon of top camber.The foam molding of making is good, need not cut arrangement substantially and just can reach the extraordinary external form product that size rectangular parallelepiped product arbitrarily also adapts to irregular type.
The utility model is applied widely, is applicable to all amino resins manufacturing foamed plastics, is specially adapted to the foam process of melamine resin, phenolic resins.

The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in detail.
The mould of manufacturing foamed plastics of the present utility model, a kind of mould of making foamed plastics, comprise cover and die coat in the mould, be positioned at the flexible mould that is of top, be positioned at the fixed mould that is of below, described flexible mould top is connected with the unit weight controller, the structure of unit weight controller is hydraulic cylinder or oil cylinder commonly used, under the effect of speed control, the speed isobaric motion by foaming is foamed it under the condition of constant voltage.The parameter of speed control is according to importing controller after the test determination, utilize the corresponding one by one of prescription to do to adjust accordingly then, reach the control of unit weight, the product that utilizes mould of the present utility model to make is a kind of cube, or makes arbitrary shape as required.
As shown in Figure 1, as a kind of embodiment of the present utility model, die coat 4 is a flexible mould, cover 3 is a fixed mould in the mould, described unit weight controller 2 is controlled the movement velocity of die coats 4 by the connecting rod 8 that is fixed on die coat outer casing top surface center, the both sides of die coat 4 are provided with guiding mechanism, put in the described fixing mould and are provided with hermetically-sealed construction 6.Described guiding mechanism comprises the fixing guide post 1 that is arranged on the die coat both sides and be fixed on the fairlead 7 that can slide on the two sides of die coat 4 on guide post, with upper and lower the moving that guarantees that movable die coat can be stable.The mould molding of this kind structure is good, and unit weight is easy to control, and mould is originally as the cube casing, be provided with mazy hermetically-sealed construction between the inside and outside cover of mould,, be suitable for making the large-size massive mould to guarantee the constant pressure of cavity body of mould 5, widely applicable, be not stressed, the restriction of temperature.
As shown in Figure 2, be another embodiment of the present utility model, described flexible mould is a cover 3 in the mould, described fixed mould is a die coat 4, put in the mould of described activity and be provided with top pressure closure, constant to guarantee cavity body of mould 5 internal pressures, unit weight controller 2 is fixed on the translational speed of middle part to overlap in the control mould of cover 3 tops in the mould.The mould of this kind structure is applicable to the processing of extraordinary external form, particularly small-sized bulk, and compression resistance is low slightly.
Below for using mould of the present utility model to make the specific embodiment of amino resins foamed plastics:
Embodiment one: control rate is by like differential curve control, and foaming height is 60cm, at this moment the unit weight controller be set at differential calculation, be 25 seconds heat time heating time, foamed time is 60 seconds, finally obtaining unit weight is the amino resins foamed plastics of 6Kg/m3.
Embodiment two: control rate is by like differential curve control, and foaming height is 55cm, at this moment the unit weight controller be set at differential calculation, be 35 seconds heat time heating time, foamed time is 95 seconds, finally obtaining unit weight is the amino resins foamed plastics of 8Kg/m3.
