At first the turn left handle 58 of rotating mechanism 56, then screw axis 57 rotates and drives nut 59 and rotates to the right on its opposite.So, just make and be fixed on the nut and outstanding guide blot 63 driven rotary rings 52 (reverse direction of arrow A among the figure) left from the slotted hole 55 of swivel eye 52.Swivel eye 52 rotates to the reverse direction of arrow A, then makes the guiding ejector pin 71 of the cam path 54 that is based in swivel eye 52 move to peripheral direction along cam path 54.Guiding ejector pin 71 moves to peripheral direction along cam path 54, drives the movable block 70 that is fixed on the guiding ejector pin 71 and all moves towards the peripheral direction of seat ring 51, and the just feasible internal diameter that is surrounded by them is enlarged.Be under this state at movable block 70, make locating ring above the metal pattern body 2 between movable block 70.
Next, handle 58 is rotated to above-mentioned reverse direction, it is mobile round about that then screw axis 57 rotates corresponding drive nut 59 round about, makes guide blot 63 driven rotary rings 52 rotate to the arrow A direction.So, the feasible guiding ejector pin 71 that is based in the cam path 54 of swivel eye 52 moves along cam path 54 inside Zhou Fangxiang.Drive the movable block 70 that is fixed on the guiding ejector pin 71 thus and move towards the center position of seat ring 51, the locating ring that clamps above the metal pattern body 2 makes it fixing, and metal pattern body and detector body just are in connection status.
Below, with the injection process of explanation injection molding material in metal pattern.In the moulding material accommodating chamber 20 of detector body 15 containers 16, accommodate the moulding material 19 of specified rate in advance, this moulding material 19 remains the heating and melting state by heater.Further, the timer by controller 40 carries out the schedule time setting of (determining the injection length of moulding material according to the volume of the die cavity 6 of metal pattern body 2 and running channel 7).
In this state, during the air supply source air supply of slave controller 40, air is transported to the upper chambers 20a of moulding material accommodating chamber 20 from first air scoop 42 by moulding material injection air supply pipe road 41.Therefore, air pushes separator disc 21 downwards, thereby moulding material 19 is transported in the moulding material passage 36 of gate valve 35.
Then, the solenoid valve of driving governor 40 by switching solenoid valve, will be opened with air supply pipe road 43 by gate valve and will be transported to the bottom compartment 27b of cylinder 18 from the 3rd air scoop 46 from the air of air supply source.Thereby as shown in Figure 2, the piston 29 in the cylinder chamber 27 is because the upwards ejection of air makes gate valve 35 rise with piston 29.Along with the rising of gate valve 35, valve pin 37 rises, and extracts from the inner chamber of gate 32,32 the inner chamber of opening the sluices, and the result injects metal pattern bodies 2 by moulding material passage 36 from gate 32 with the moulding materials in the moulding material accommodating chamber 20 19.
In other words, when gate 32 was opened, moulding material 19 was injected in the die cavity 6 by running channel 7.In case when being filled into the moulding material 19 of specified rate in die cavity 6 and the running channel 7,, will close with air supply pipe road 45 by gate valve, supply with upper chambers 27a from second air scoop 44 from the air of air supply source according to signal switching solenoid valve from timer.
Thereby as shown in Figure 3, the pistons 29 in the cylinder chamber 27 descend under the air pressure effect, the result, with piston 29 be gate valve 35 declines of one, valve pin 37 closed shutters 32.In this case, valve pin 37 enters the inner chamber of gate 32, and gate 32 is closed, and can stop the outflow of moulding material 19 fully, and then prevents that moulding material 19 from flowing down from gate 32.
So, in die cavity 6 that moulding material 19 is filled into metal pattern body 2 and running channel 7 after, when metal pattern body 2 unloaded detector body 15, detector body 15 can not flow down attached on the metal pattern body 2 from gate 32 because of moulding material 19.
The moulding material 19 that is filled in the die cavity 6 is carried out cooling curing, can obtain the formed products sample.From die cavity 6, take out the formed products sample,, can check out the crudy situation of injection molding forming metal pattern, particularly die cavity 6 by visual or use microexamination formed products sample.
