Abstract
A preparation method of a foam product comprises the steps: firstly moving down an upper pressing die to a position with an interval distance of 4-5 mm to a lower molding die; secondarily, automatically feeding to the molding cavity of the lower molding die; after completing feeding, continuously moving down the upper pressing die and tightly locking with the lower molding die; blowing steam downward through inner vent holes of the upper pressing die by a steam system, then blowing steam upward through inner vent holes of the lower molding die by the steam system, and making the steam penetrate the product; heating the upper pressing die and the lower molding die at the same time; after heating, shutting the steam system, making water get into the vent holes of the upper pressing die and the lower molding die via a cooling system for water cooling; and finally after molding, opening the dies and discharging. The preparation method has the advantages of being easy to operate, simple in processing flow, low in cost, clean, environment-friendly, free in raw material waste, free in over high energy consumption and the like.
Description
Technical field
The present invention relates to a kind of foamed product, be specifically related to a kind of preparation method of foamed product.
Background technology
Not only work flow is loaded down with trivial details for existing plastic foam product preparation method, cost is high, and has increased danger, is not suitable for suitability for industrialized production.
Summary of the invention
The present invention seeks to provide in order to overcome the deficiencies in the prior art that a kind of work flow is simple, handled easily, be suitable for the preparation method of the foamed product of suitability for industrialized production.
For achieving the above object, the technical solution used in the present invention is: a kind of preparation method of foamed product comprises step: at first top die is displaced downwardly to compacted under mould 4-5mm place, interval; Secondly, the interior auto feed of the forming cavity of shaping mould downwards; After reinforced complete, be locked on the compacted under mould after the top die continuation is descending, vapour system is at first by the downward steam blowing of passage in the top die, and then vapour system makes upwards steam blowing by passage in the compacted under mould again, make steam penetrate goods, top die and compacted under mould are heated simultaneously; After heating, vapour system quits work, and cooling system carries out water-cooled by the passage water inlet of top die and compacted under mould; At last, die sinking discharging after the moulding.
Because the utilization of technique scheme, the present invention compared with prior art has following advantages:
The preparation method of a kind of foamed product of the present invention program, easy operating control, work flow is simple and cost is low, has advantages of clean, environmental protection, do not waste raw material and avoids excessive energy consumption.
Description of drawings
Below in conjunction with accompanying drawing technical solution of the present invention is described further:
Accompanying drawing 1 is the structural representation that uses moulding press among a kind of foamed product preparation method of the present invention;
Wherein: 1, top die; 2, compacted under mould; 3, control system; 4, cooling system; 5, vapour system; 6, passage; 7, approach switch.
The specific embodiment
The present invention is described in further detail below in conjunction with drawings and the specific embodiments.
Accompanying drawing 1 uses moulding press among the foamed product preparation method of the present invention, and this moulding press has top die 1, compacted under mould 2, control system 3, cooling system 4, vapour system 5; Described control system 3 is electrically connected with top die 1, compacted under mould 2, upper cooling system 4, vapour system 5 respectively; Be respectively equipped with the passage 6 that is connected with upper cooling system 4, vapour system 5 on described top die 1, the compacted under mould 2; Described top die 1 can move towards and away from the direction of described compacted under mould 2; Described top die 1 is moved downward to compacted under mould 4-5mm place, interval and is provided with approach switch 7; Described approach switch 7 is electrically connected described control system 3.During production and processing, at first top die is under the drive of turbine and worm, be displaced downwardly to compacted under mould 4.5mm place, interval, after approach switch 7 is sensed the position signalling of top die 1, send this positional information to control system 3, control system 3 control feeding devices begin the interior auto feed of forming cavity of downward shaping mould 2; After reinforced complete, top die 1 continues to be locked at after descending on the compacted under mould 2, vapour system 5 is first by the downward steam blowing of passage in the top die 1, then vapour system 5 makes steam to blowing up by the passage in the compacted under mould 2 again, make steam penetrate goods, top die 1 is heated simultaneously with compacted under mould 2; After heating, vapour system 5 quits work, and cooling system 4 carries out water-cooled by the passage water inlet of top die 1 with compacted under mould 2; Last die sinking discharging.
Below only be concrete exemplary applications of the present invention, protection scope of the present invention is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, all drop within the rights protection scope of the present invention.
Claims (1)
1. the preparation method of a foamed product comprises step: at first top die is displaced downwardly to compacted under mould 4-5mm place, interval; Secondly, the interior auto feed of the forming cavity of shaping mould downwards; After reinforced complete, be locked on the compacted under mould after the top die continuation is descending, vapour system is at first by the downward steam blowing of passage in the top die, and then vapour system makes upwards steam blowing by passage in the compacted under mould again, make steam penetrate goods, top die and compacted under mould are heated simultaneously; After heating, vapour system quits work, and cooling system carries out water-cooled by the passage water inlet of top die and compacted under mould; At last, die sinking discharging after the moulding.
