The accompanying drawing to be used needed for having technology description is briefly described, it should be apparent that, drawings in the following description are only this
Some embodiments of invention, for those of ordinary skill in the art, on the premise of not paying creative work, can be with
Other accompanying drawings are obtained according to these accompanying drawings.
Fig. 1 is the flow chart of the mosaic technology of a kind of copper nut that one embodiment of the invention is provided and plastic parts.
Specific embodiment
To make the object, technical solutions and advantages of the present invention clearer, technical scheme will be carried out below
Detailed description.Obviously, described embodiment is only a part of embodiment of the invention, rather than whole embodiments.Base
Embodiment in the present invention, those of ordinary skill in the art are resulting on the premise of creative work is not made to be owned
Other embodiment, belongs to the scope that the present invention is protected.
As shown in figure 1, the invention provides a kind of copper nut and the mosaic technology of plastic parts, it is comprised the following steps：
S1, making original workpiece.
S2, copper nut, and the stationary positioned plug in copper nut are imbedded in original workpiece using heating embedding technique.Its
In, the axis of copper nut coincides with the axis of location mandril.
S3, mould is done to be embedded with the original workpiece of copper nut and location mandril, its detailed process is：
1) for product prototype makes peripheral frame；
The peripheral frame of one side opening is made of first to the 5th block of coaming plate, the junction between each coaming plate is entered using PUR
Row sealing.Product prototype is when being put into peripheral frame, it is necessary to the top of peripheral frame is higher by the 5~10cm of top of product prototype.
2) mould silica gel is made, it specifically includes following steps：
Stirred after silica gel is mixed with curing agent, until milky is presented.Wherein, the weight ratio of silica gel and curing agent
It is 100:1, mixing time is set as 2~2.5min.
Mixture to silica gel after stirring and curing agent carries out vacuum defoamation, obtains mould silica gel.The vacuum defoamation time sets
It is set to 8~12min.
3) mould silica gel is poured into peripheral frame, product prototype is put into peripheral frame, make mould, it specifically includes following step
Suddenly：
Part mould silica gel is poured into peripheral frame.
The original workpiece that copper nut and location mandril will be embedded with is put into peripheral frame.
Remaining part mould silica gel is poured into peripheral frame.
Peripheral frame is put into vacuum machine, the mould silica gel in peripheral frame is carried out vacuumizing final vacuum.Pumpdown time sets
It is 10~15min.
In peripheral frame placement positioning slightly and stirrup, position of the amendment product prototype in peripheral frame.Wherein, position slightly and add
The distance between strong rod is set as 80~120mm.
Product prototype in peripheral frame and mould silica gel are solidified.Wherein, curing mode can using normal temperature cure or
Heating cure.Normal temperature cure generally makes silica gel spontaneous curing when 25-30 spends.The temperature of heating cure is set as 42~45 DEG C.
S4, first time die sinking is carried out, obtain mould.
1) enclosing is removed, obtains being enclosed with the mould of product prototype.
2) mould is separated along the parting line for pre-setting, takes out product prototype, mould inside forms die cavity.Wherein, divide
Molded line can be using wave or jaggies etc., so as to facilitate follow-up matched moulds.
S5, mould is poured into a mould.
1) pouring slot and exhaust outlet are opened up on mould.
2) copper nut is placed on mould by the positioning action by location mandril placement in a mold, and using location mandril
In.For ease of copper nut is placed in a mold, copper nut can be fixed with location mandril with glue first, then will positioning
Plug is placed in a mold.
3) in expecting to pour into the die cavity of mould inside by AB by pouring slot.Further, before AB material are poured into die cavity,
Need to pre-process AB material and mould, it specifically includes following steps：
After two kinds of liquid of A and B are heated into 25~30 DEG C, it is put into vacuum tank at the vacuum defoamation for carrying out more than 10min
Reason.
Mould is heated to 70~80 DEG C, when the temperature of mould is too low, subsequent cure can be caused incomplete so that mould
Physical property is bad.
4) casting complete solidify afterwards, heating.
The solidification of 60~70min is carried out in 70~80 DEG C of insulating box.
The secondary solidification of 2~3 hours can be carried out in 100~150 DEG C of insulating box if necessary.Further, solidify
After model can be fixed using fixture, to prevent it from deforming.
S6, second die sinking is carried out, obtain being inlaid with the plastic parts of copper nut.
Plastic parts is taken out, the post processing such as the mouth of a river and flash, polishing is removed to plastic parts.Inlayed in the plastic parts for obtaining
There is copper nut.
Silicon moulds are a kind of trial-production moulds, for making stage die or small lot mould.Silicon moulds have fabrication cycle it is short,
The advantages of low cost, elastic good, workpiece are easy to the demoulding and good replicability.Copper nut of the present invention passes through with the mosaic technology of plastic parts
Copper nut is imbedded in advance in silica gel mould, when part is turned over plastic parts one-shot forming, and copper nut is embedded in plastic parts.By
In on moulding process, the present invention can make the copper nut inlayed and plastic parts one-shot forming, therefore the present invention can be simpler
Just inlaying for copper nut and plastic parts is realized, and then the small batch workpiece production that copper nut is inlayed with plastic parts can be carried out.
The present invention can provide the user a kind of inexpensive, time saving, easily sample making approach, and it is more suitable for making very small amount, various
Product.
The above, specific embodiment only of the invention, but protection scope of the present invention is not limited thereto, and it is any
Those familiar with the art the invention discloses technical scope in, change or replacement can be readily occurred in, should all contain
Cover within protection scope of the present invention.Therefore, protection scope of the present invention should be based on the protection scope of the described claims.
