Into nano level pit, resin is made to link together with metal, to obtain gold modeling integrated molding product.
But nanometer injection molding technology（NMT）It is first to handle metal, then by treated, metal is put into note
In mould, then metal surface carry out injection molding so that injection mold it is complicated, cost is higher, and technique is more
It is cumbersome.
Invention content
In view of the above shortcomings of the prior art, the technical problem to be solved by the present invention is to：How a kind of technique phase is provided
To relatively simple, plastics hot-press molding method integrated with the plastic-metal that metal is firmly combined with and simple in structure, manufacturing cost
It is relatively low, operate eaily plastic-metal integration heat pressing forming device.
In order to solve the above-mentioned technical problem, present invention employs the following technical solutions：
A kind of plastic-metal integration heat pressing forming device, which is characterized in that including rack and hot-die, the rack
It is upper to be located at the top of the bottom plate with bottom plate and the pressure head that lifted, the pressure head；It is provided with and is used on the bottom plate
The heat-conducting plate of heating；The hot-die includes the lower mold body being mounted on heat-conducting plate and the upper die body on pressure head；It is described
Have in lower mold body for the locating slot for placing metal substrate and plastic base to be laminated, the upper die body has and the locating slot
Matched convex block, when the upper die body is pushed with the pressure head, the convex block can extend into the locating slot, and the convex block
Minimum spacing between the locating slot is less than the sum of the thickness of the metal substrate and plastic base that wait for hot pressing.
Using the above structure, the heat of heat-conducting plate can be transmitted to metal substrate and plastics in locating slot by lower mold body
On substrate, the surface to be plastic base is melted；Since the minimum spacing between convex block and locating slot is less than the gold for waiting for hot pressing

The lower surface of substrate keeps support, and plastic base in hot pressing is avoided to deform.
A kind of plastic-metal integration hot-press molding method, including first the surface of metal substrate is handled, make its table
Face generates nano aperture structure；It is characterized in that, further including following steps：It will wait for that the plastic base of hot pressing overlays that treated
On metal substrate, metal substrate and plastic base are preheated, when the surface of plastic base starts to melt, to plastics
Substrate, which carries out pressure, makes plastic base be pressed on the surface of metal substrate, and the surface melt layer of plastic base is made to penetrate into the metal
In the nano aperture on the surface of substrate；It is hot-forming that plastic-metal integration can be completed in taking-up after cooling.
It is directly on metallic substrates by molding plastic base integration hot pressing, and traditional using the above method
Nanometer injection molding technology（NMT）It compares, the injection molding of plastics is carried out without face on metallic substrates, avoid manufacture complexity
Injection forming mold can simplify the structure of mold, convenient for manufacture, advantageously reduce production cost, simplification of flowsheet improves
Working efficiency.In addition, generating nano aperture structure since the surface of metal substrate carries out processing, the plastics of melting can be made to press
It is penetrated into nano aperture under the action of power, to improve the bond strength of plastic base and metal substrate.
As an optimization, plastic base and metal substrate are carried out using above-mentioned plastic-metal integration heat pressing forming device
Heating and pressure.
As an optimization, before preheating, the surface of the plastic base is processed by shot blasting, removes skim-coat rubber.
In this way, the rubber on removal plastic base surface, avoids plastic base from generating membrane structure, the plastics of melting are influenced
Mobility can be penetrated into preferably in nano aperture after making the melt surface of plastic base, improve the bond strength of the two.
As an optimization, when pressing to plastic base, 2 ~ 10min of pressurize.
Since the plastics viscosity of melting is larger, mobility is poor, and the flowing of plastics can be increased by carrying out pressurize to hot-die
Time ensures that more molten plastics penetrate into nano aperture, improves the bond strength of plastic base and metal substrate.
As an optimization, when pressing to plastic base, vibration is applied to plastic base and metal substrate, vibration frequency is
1~100KHz。
In this way, by vibration make the melting layer of plastic base by highdensity plywood after, the stream of melting layer thinning because of shearing
Dynamic property increases, and the probability that plastic melt enters the nano aperture of metallic substrate surfaces increases, while vibration also acts as collaboration melt
The effect in uniform fold metal-surface nano area.To improve the bond strength of plastic base and metal substrate.
In conclusion the method for the present invention has technique relatively simple, plastics and metal bond strength are higher, are conducive to drop
The advantages that low production cost, apparatus of the present invention have it is simple in structure, manufacturing cost is relatively low, operates the advantages that more convenient.
