Abstract

The invention relates to a sand plastic craft. The processing technology for the sand plastic craft comprises the following steps: 1, placing rectangular stones with cylindrical hollow cavities of different specifications on a heating panel; 2, pouring half of clay or plaster into the cylindrical hollow cavities; 3, forming grooves with the shape the same as a required plastic model in the top of the clay or the plaster; 4, covering a plastic panel at the upper part of the clay groove or the plaster groove; 5, pouring fine sand on the plastic panel until the cylindrical hollow cavities are filled up, and gently pressing; 6, heating the heating panel; 7, heating and softening the plastic panel, wherein the middle part of the plastic panel deforms and concaves to be clung to the groove under the squeezing by the fine sand; 8, pouring out the fine sand after cooling, taking out and trimming a plastic model, so as to obtain a plastic model processed well. The sand plastic craft is simple to operate, and saves cost.

Description

A kind of sand sculpture technique
Technical field
The present invention relates to technical field of plastic, be specifically related to a kind of sand sculpture technique.
Background technology
Plastic processing is that the development along with synthetic resin gets up, and the development of it and plastics machinery promotes mutually.Many plastic processing technologies are to be referred from rubber, metal and pottery processing.Plastic processing history can be traced back to the nineties in 19th century, after celluloid is born, inflammable because of it, can only make block by die pressing, more machined one-tenth sheet material, the processing of the sheet material available heat method of forming.This is plastic processing the earliest.Cast molding is come out along with phenolic resins and is studied successfully; Injection moulding starts from the twenties in 20th century, be used to processing cellulose acetate and polystyrene; The mid-1930s, the flexible PVC extrusion molding is succeeded in developing, the corresponding appearance of the single screw extrusion machine of plastics special use; Double screw extruder also put into production in 1938.The beginning of the forties, made polyurethane foam plastics, blow molding technology is for the production of the polyethylene hollow product.Nineteen fifty-two reciprocating screw type injector appearance, make injection molding technology enter into a new stage.60~seventies, the plastic processing technology that new development is got up has: the new forming method of various reinforced plastics, and as winding, pultrusion, sheet molding moulding, reaction injection molding, structural foam moulding, Profile Extrusion, sheet material solid phase forming and coextrusion, common injection moulding etc.Enter the eighties, plastic processing towards efficiently, at a high speed, high accuracy, energy-conservation, maximization or the future development such as extra small, ultra-thin, computer technology enters this field, and whole plastic processing technology is brought up to a new height.
At present, use more be blow molding technology and plastic uptake technology, blowing also claims hollow blow molding, a kind of development is plastic working method rapidly, according to the parison preparation method, blowing can be divided into extrusion-blown modling and injection-blow molding, and new development is got up multilayer blow moulding and stretch-blow; The plastic uptake cardinal principle is by after open and flat plastic hard plate material heating deliquescing, adopts vacuum suction in die surface, and cooling aftershaping, be widely used in the industries such as plastics package, lamp decoration, advertisement, decoration.
But the machine that blow molding technology and plastic uptake technology are equipped with involves great expense, cause the too much burden of producer.
Summary of the invention
The object of the present invention is to provide a kind of cheap plastic processing.
The present invention adopts following technical scheme to achieve these goals:
A kind of sand sculpture technique, described processing technology step is as follows:
1. will be placed on heating plate with the rectangle stone of the cylindrical hollow of different size;
2. in cylindrical hollow, pour half clay or gypsum into;
3. at clay or gypsum top, stamp the groove of required plastic pattern shape;
4. above clay or gypsum groove, cover the lastblock plastic plate;
5. on plastic plate, pour fine sand into, until cylindrical hollow is filled to light the pressure;
6. heating plate is heated;
7. plastic plate is through thermoplastic, and because being subjected to the extruding of fine sand, the plastic plate middle part can the distortion depression be close in groove;
8. after cooling, pour out fine sand, take out plastic pattern, compile through repairing the plastic pattern that obtains processing.
Processing step of the present invention further is set to: in clay or gypsum, be attached with resistant to elevated temperatures thermo detector.
Processing step of the present invention further is set to: the size of groove as calculated, is the thickness that the size of required plastic pattern adds plastic plate.
Processing step of the present invention further is set to: the temperature to the plastic plate heating is the critical point of plastic plate softening transform.
Have the sand sculpture technique of above-mentioned steps, cheap, simple and practical.
The specific embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below the present invention is further set forth.

4. above the clay groove, cover lastblock PVC plastic plate;
5. on the PVC plastic plate, pour fine sand into, until cylindrical hollow is filled to light the pressure;
6. heating plate is heated;
7. the PVC plastic plate is through thermoplastic, and because being subjected to the extruding of fine sand, PVC plastic plate middle part can the distortion depression be close in groove;
8. after cooling, pour out fine sand, take out plastic pattern, compile through repairing the plastic pattern that obtains processing.
Processing step of the present invention further is set to: in clay, be attached with resistant to elevated temperatures thermo detector.
Processing step of the present invention further is set to: the size of groove as calculated, is the thickness that the size of required plastic pattern adds the PVC plastic plate.
