Contact surface between part 25.
As shown in figure 4, heating closure member 25 be cylindrical in shape in certain embodiments, the shape of its transverse section outline and
Size is adapted with the shape and size of the transverse section of the second resettlement section 213 of pedestal 21, can to heat closure member 25
Closely it is contained in the second resettlement section 213.In certain embodiments, closure member 25 is heated less than the second resettlement section 213
Length, makes which can be along the length direction of the second resettlement section 213 the 3rd position away from the surface 210 of pedestal 21
Move back and forth between 4th position (position shown in Fig. 7) on (position shown in Fig. 6) and a close surface 210.When being located at
When on the 3rd position, heating closure member 25 is separated with sealing boss forming space, seals energy in boss forming space to allow
It is enough to form sealing boss 101.When on the 4th position, heating closure member 25 is extend in sealing boss forming space,
With the sealing boss generation effect with molding.
In certain embodiments, heat closure member 25 central through hole may include the Part I 250 of a column with
And the Part II 252 of taper.The transverse shape and size of Part I 250 and the foreign steamer storehouse of the transverse section of gas injection element 23
Shape and size match, so as to gas injection element 23 can be arranged in heating closure member 25 in.The upper end of Part II 252
It is in close proximity to the lower end of Part I 250.Heating closure member 25 may include electric cautery in certain embodiments.
With reference to forming process, the present invention will be further described.
When plastic parts in some embodiments of the invention adopts 1 molding of injection forming equipment, it may include following steps：
(1) require to calculate plastic parts volume V according to part dimension and wall thickness.
(2) injected by the plastic cement melt 100 slightly larger than plastic parts volume (for example, 1.05V) by injection hole (not shown)
The die cavity of injection forming equipment 1, the injection hole may differ from gas injection port.
(3) compressed gas are injected by the gas injection passage of gas injection device 20 in the plastic cement melt 100 in die cavity so that modeling
Glue melt 100 is full of whole die cavity in the presence of compressed gas and forms sealing boss 101.Specifically, plastic cement melt 100 with
Surface of mould cavity contact position first solidifies, while 100 flow front of plastic cement melt is minimum along resistance under the driving of compressed gas
Flow forward is continued in direction, until being full of whole die cavity, and forms the sealing boss 101 around gas injection port.
(4) dwell time is set according to the size of part, plastic cement melt 100 is relatively evenly attached on surface of mould cavity,
And coagulation forming.
(5) compressed gas in the plastic parts after molding are discharged by the exhaust passage of gas injection device 20.
(6) liquid is injected toward in plastic parts by the reservoir channel of gas injection device 20, and is reserved for liquid appropriate hot swollen
Swollen space.Specifically, it is assumed that the thermal coefficient of expansion of liquid is x, and the volume in die cavity is V1, and the operational difference of plastic parts is Δ T,
The volume for then injecting liquid is calculated by formula V2=(V1/ (1+x* Δ T)) * 95%.
(7) first position as shown in Figure 5 of gas injection element 23 is driven to be moved upwards up to the second position shown in Fig. 6 so that
Gas injection element 23 is departed from sealing boss 101.
(8) heating closure member 25 is heated to into predetermined temperature (such as 260 DEG C)；
(9) heating the 3rd position as shown in Figure 6 of closure member 25 is driven to move to the 4th position shown in Fig. 7, will envelope
Mouth 101 heat distortion of boss simultaneously extrudes the purpose for reaching sealing to centre.
(10) cooling heating closure member 25 makes sealing resolidification finally realize liquid 200 is sealed in plastic parts 20
Portion, the last demoulding take out forming plastic cement part.
Fig. 8 and Fig. 9 show a kind of LED lamp radiating shell 300, and the LED lamp radiating shell 300 includes the master of cup-shaped
Body 391, the main body 391 can adopt the plastic material of excellent heat dissipation performance to pass through injection mo(u)lding.It is close on the side wall of the main body 391 to open
The position of mouth can also by the annular accommodation space 303 of the formation one of gas injection.As shown in figure 9, the annular accommodation space 303
Transverse section abbreviation triangle.The annular accommodation space 303 is filled with the liquid such as water, coolant, to realize liquid auxiliary heat dissipation.Can
To understand ground, accommodation space 303 is not limited to annular, and which can also be any shape.LED lamp radiating shell 300 can be adopted
Made with above-mentioned injection forming equipment 1 and above-mentioned injection moulding method, specifically, as long as cavity shape correspondence LED lamp is dissipated
The shape of hot housing 300 is designed, and this point for a person skilled in the art, is easily achieved,
This repeats no more.
The injection forming equipment, is disappeared while radiating plastic parts that can be empty aborning by arranging the closure member
Except the charging aperture that blowing is formed, the surface of product is made to keep smooth.So as to be needed what two steps can just be completed in the prior art
Technology is merged into a step so that the LED lamp radiating shell and its injection forming equipment have can seal, process is simple it is excellent
Point.
Injection forming equipment in some embodiments of the invention can be while production radiating plastic parts, by liquid infusion
To in radiating piece plastic cement, to improve the radiating effect of LED lamp radiating shell, the liquid auxiliary heat dissipation pair realized by the present invention
The property of liquid does not have anything to specially require, and can just be realized with water.The present invention has saved life while heat dispersion is improved
Produce cost, reduce manufacture difficulty.
It should be understood that the exhaust passage be disposed to reservoir channel can be injected liquid into.Need not inject
The occasion of liquid, can be not provided with the exhaust passage and the reservoir channel, so as to simplify structure.Certainly, the plastic cement melt 100
Injection hole can also be arranged on the gas injection element 23, so as to simplify structure.The closure member 25 can not have heating function.
Because extruding the plastic cement melt 100 using the closure member 25 in 100 cooling procedure of plastic cement melt and can also realize sealing work(
Energy.
It should be pointed out that for those skilled in the art, without departing from the principles of the present invention
Several improvements and modifications, these improvements and modifications also should be regarded as protection scope of the present invention.
