Description
Technical field
A kind of plastics suction mould is the utility model is related to, belongs to plastics sucking moulding technical field.
Background technology
Plastic uptake is a kind of plastic processing, and cardinal principle is after open and flat plastic hard plate heating is softened, using vacuum
Die surface is adsorbed in, aftershaping is cooled down, is widely used in plastics package, lamp decoration, advertisement, ornament lamp industry.
Plastics suction mould, refer to mould used during plastic uptake production, mould is drilled with aperture, the plastics for vacuum suction thermalization
Stiff sheet, form plastic uptake product.Important processing step is to vacuumize and be cooled and shaped in plastic uptake technique, mold cavity it is closed
Property influence the speed that vacuumizes and last vacuum, can finally cause in plastic products containing bubble or hollow phenomenon occur；
And the process cooled down also directly affects the shaping of plastic products, cause product inside and outside uneven in temperature if cooling is insufficient and produce
Stress deformation.Therefore the design of plastics suction mould, which needs to improve mould, vacuumizes performance and cooling effect, to improve Blister product
Final mass.
The content of the invention
Purpose：In order to overcome the deficiencies in the prior art, the utility model provides a kind of Novel plastic suction mould.
Technical scheme：In order to solve the above technical problems, the technical solution adopted in the utility model is：
A kind of Novel plastic suction mould, including main mould and secondary mould, wherein main mould have a plastic uptake die cavity, main mould with after secondary mould matched moulds
Form closed cavity space；Circulating cooling water pipe is set in the main mould；The main mould sets aspirating hole, and aspirating hole one end connects
Pumping equipment is connect, one end connects with die cavity；The lower surface of the secondary mould is that the one side being bonded with main mould opens up steam vent, steam vent
It is connected by airway with blower fan；Some raised ribs of upper surface spaced set of the main mould, secondary mould lower surface are set
Some grooves, the raised rib can be embedded in corresponding groove.
Further, the cooling water pipe is arranged around die cavity.
Further, the blower fan has hot blast shelves and cold wind shelves, changeable.
Further, height of the depth of the groove slightly larger than raised rib.
Further, it is cased with rubber washer on the raised rib.
Further, the raised rib and groove are preferably provided with quantity as 4, be separately positioned on mould it is forward and backward,
Left and right four direction.
Further, aspirating hole is correspondingly arranged at the corner of the mold cavity, the aperture ratio of the aspirating hole at corner is put down
Aspirating hole aperture at face is big.
Beneficial effect：Plastics suction mould provided by the utility model, steam vent is opened up on secondary mould and is connected with blower fan, by blower fan
Hot blast shelves are adjusted to heat and soften plastics；Raised rib coordinates with groove so that main mould is bonded more firm with secondary mould
With it is close, mould impermeability is good, is advantageous to reach required vacuum；Cooling stage, blower fan is adjusted to cold wind shelves, it is cold with circulating
But water is effectively cooled down from upper surface and lower surface to plastic products respectively, improves product molding quality.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is further described below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of Novel plastic suction mould, including main mould 1 and secondary mould 2, main mould have plastic uptake die cavity, closed with secondary mould
Closed cavity space is formed after mould.Circulating cooling water pipe is provided with the main mould, wherein water inlet pipe 3 and outlet pipe 4 is distinguished
Main mould both sides are arranged on, cooling water pipe is arranged around die cavity, can improve cooling effect.Aspirating hole 5 is arranged around main mould die cavity, is taken out
Stomata one end is connected with die cavity, and the other end is connected with air-extractor, for the operation vacuumized to plastic uptake die cavity.In mould
Have and aspirating hole is arranged at die cavity corner, and the aspirating hole aperture at corner at the aperture ratio plane of aspirating hole is big, because corner
Place is unfavorable for vacuumizing, such as aspirating hole aperture is set to 0.7mm at plane, and aspirating hole aperture is then set to 1.0mm at corner.
Vacuum plastics sucking molding technique is a kind of thermoforming processing method, using thermoplastic plastic sheet, manufactures shedding shell
A kind of method of product.Plastic sheet is cut into certain size to heat and soften, by the draught head or mechanical pressure on sheet material two sides,
It is set to be posted after deforming on Die cavity profile face, then by cooling and shaping.The aspirating hole set in main mould, then it is to utilize
Vacuum plastics sucking molding technique obtains plastic products.When vacuumizing, the seal in mold cavity space influences vacuum, if mould
Seal is bad, can produce bubble between plastic sheet and Die cavity profile in plastics sucking moulding so that surface of plastic products
It is uneven whole.
The utility model sets some raised ribs 8 in main mould upper surface, and secondary mould lower surface sets some grooves 9, institute
Stating rib 8 can just be embedded in groove 9, and the position of raised rib 8 and groove 9 corresponds up and down.The depth of groove 9 is omited
More than the height of rib 8, while rubber washer is cased with rib 8, it is ensured that the seal after rib is chimeric with groove.Preferred scheme
In, the quantity of raised rib and groove is set to 4, is separately positioned on the front, rear, left and right four direction of mould.Rib and recessed
The quantity of groove is excessively not easy to the installation of main mould and secondary mould.
The lower surface of the secondary mould 2, i.e., the one side being bonded with main mould 1 open up steam vent 6, and steam vent is uniformly distributed, and is passed through
Cross airway with blower fan 7 to be connected, blower fan 7 has hot blast shelves and cold wind shelves, can according to circumstances switch over.Start in plastics sucking moulding
It is preceding, it is necessary to heated to plastic sheet, blower fan is now adjusted to hot blast shelves, plastic sheet is heated；In plastics sucking moulding
The cooling stage of technique, blower fan is adjusted to cold wind shelves, whole die cavity environment is cooled down, coordinates the work of recirculated cooling water
With, plastic products are cooled from top to bottom, plastic products internal and external temperature is reached consistent, raising Forming Quality.
Described above is only preferred embodiment of the present utility model, it should be pointed out that：For the common skill of the art
For art personnel, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these improve and
Retouching also should be regarded as the scope of protection of the utility model.
