Description
Technical field
The present invention relates to a kind of plastics suction mould, belong 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, refers to mould used when plastic uptake is produced, and mould is drilled with aperture, for the plastics of vacuum suction thermalization
Stiff sheet, forms plastic uptake product.Important processing step is to vacuumize and cooling shaping in plastic uptake technique, mold cavity it is closed
Property the influence speed and last vacuum that vacuumize, can finally cause in plastic products containing bubble or hollow phenomenon occur；
And the process for cooling down also directly affects the shaping of plastic products, if cooling is insufficient and causing product inside and outside uneven in temperature and producing
Stress deformation.Therefore the design of plastics suction mould needs to improve mould and 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 present invention to provide a kind of Novel plastic suction mould.
Technical scheme：In order to solve the above technical problems, the technical solution adopted by the present invention is：
A kind of Novel plastic suction mould, including main mould and secondary mould, wherein main mould have plastic uptake die cavity, are formed after main mould and secondary mould matched moulds
Closed cavity space；Circulating cooling water pipe is set in the main mould；The main mould sets aspirating hole, and the connection of aspirating hole one end is taken out
Gas is equipped, and one end connects with die cavity；The lower surface of the secondary mould is that the one side fitted with main mould opens up steam vent, and steam vent passes through
Airway is connected with blower fan；The some raised ribs of upper surface spaced set of the main mould, secondary mould lower surface sets some
Groove, 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 is preferably provided with quantity for 4 with groove, be separately positioned on mould it is forward and backward,
Left and right four direction.
Further, correspondence arrangement aspirating hole 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：The plastics suction mould that the present invention is provided, opens up steam vent and is connected with blower fan on secondary mould, blower fan is adjusted to
Hot blast shelves are heated and softened to plastics；Raised rib and groove fit so that main mould is fitted more firmly and tight with secondary mould
Close, mould impermeability is good, is conducive to reaching required vacuum；Cooling stage, is adjusted to cold wind shelves, with recirculated cooling water by blower fan
Plastic products are effectively cooled down from upper surface and lower surface respectively, product molding quality is improved.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
Specific embodiment
The present invention 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 has plastic uptake die cavity, with the conjunction of 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
Arrange that the aspirating hole aperture at aspirating hole, and corner at the aperture ratio plane of aspirating hole is big at tool die cavity corner, 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 on Die cavity profile face after deforming, then by cooling and shaping.The aspirating hole set in main mould, then be to utilize
Vacuum plastics sucking molding technique obtains plastic products.When vacuumizing, the seal influence vacuum in mold cavity space, 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 present invention sets some raised ribs 8 in main mould upper surface, and secondary mould lower surface sets some grooves 9, the rib
Bar 8 can be just embedded in groove 9, and raised rib 8 is corresponded up and down with the position of groove 9.The depth of groove 9 is slightly larger than
The height of rib 8, while being cased with rubber washer on rib 8, it is ensured that the seal after rib is chimeric with groove.In preferred scheme,
Raised rib is set to 4 with the quantity of groove, is separately positioned on the front, rear, left and right four direction of mould.Rib and groove
Quantity be 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 fitted with main mould 1 opens up steam vent 6, and steam vent is uniformly distributed, and passes through
Cross airway to be connected with blower fan 7, 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 that blower fan is now adjusted to hot blast shelves, it is necessary to heated to plastic sheet, plastic sheet is heated；In plastics sucking moulding
The cooling stage of technique, cold wind shelves are adjusted to by blower fan, and whole die cavity environment is cooled down, and coordinate the work of recirculated cooling water
With, plastic products are lowered the temperature from top to bottom, plastic products internal and external temperature is reached unanimously, improve Forming Quality.
The above is only the preferred embodiment of the present invention, it should be pointed out that：For the ordinary skill people of the art
For member, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications also should
It is considered as protection scope of the present invention.
