The utility model provides an injection molding machine with exhausting function's theory of operation as follows:

when the injection molding machine is used, firstly, an external power supply is connected, the air cylinder 31 is opened, the piston rod 33 is extended, the movable mold 2 is pushed to move towards the fixed mold 4, meanwhile, due to the matching of the sliding block 26 and the sliding rail 27, the moving process is more stable, the movable mold 2 and the fixed mold 4 are tightly attached together by utilizing the matching of the limiting groove 23 and the limiting block 24, the injection molding is convenient, then materials are put into the feed hopper 7 through the feed inlet 11, then the heating plate 15 starts to work to heat the materials in the feed hopper 7, meanwhile, the first driving motor 10 drives the stirring shaft 9 to start rotating so as to drive the stirring blades 8 and the transverse plate 12 to rotate, the melting rate of the materials is accelerated and more uniform, then the material stopping valve 5 is opened, the melted materials flow into the material barrel 18, the rotation of the feeding screw rod 19 is driven by the second driving motor 20, so that the melted materials flow into, meanwhile, in the process of rotation of the feeding screw rod 19, gas in the molten material is more easily dispersed, the gas enters the second exhaust pipe 43 through the first exhaust pipe 42, the pressure intensity increases along with the increase of the gas, the movable block 41 is jacked up, the second spring 45 is compressed, the gas flows into the third exhaust pipe 44 through a gap between the jacked movable block 41 and the inner side of the second exhaust pipe 43 and is discharged outwards through the through hole 40, when the gas pressure intensity is insufficient, the movable block 41 is pressed down under the action of the elastic force of the second spring 45 to block the second exhaust pipe 43 and the inclined side wall of the second exhaust pipe 43, the accidentally-blown material also quickly falls into the material barrel 18, the situation that the material flows out and blocks the first exhaust pipe 42 cannot occur, the molten material is injected into the fixed mold 4 through the diversion channel 3 to start injection molding, and after a product is cooled and formed, the cylinder 31 drives the piston rod 33 to contract, thereby drive moving die utensil 2 toward returning and contract, when returning and contract to the certain degree, moving die utensil 2 inside one side hugs closely fixed block 39, continue to return and contract, because fixed plate 37 is fixed, fixed block 39 can compress first spring 38 and promote ejector pad 36, make the product drawing of patterns more easily, when other material during operation need be changed, inject the cleaning solution into feed hopper 7 through feed inlet 11 earlier, then drive the rotation of (mixing) shaft 9 through a driving motor 10, thereby drive the rotation of stirring leaf 8 and scraper blade 13, wash feed hopper 7, wash remaining material, later open stagnant water valve 16, with sewage through the drain pipe 17 discharge feed hopper 7 outer can.

1. through set up stirring leaf 8 in feeder hopper 7, (mixing) shaft 9 and scraper blade 13, when other material during operation need be changed, earlier through feed inlet 11 to the interior cleaning solution that injects of feeder hopper 7, then drive the rotation of (mixing) shaft 9 through a driving motor 10 to drive the rotation of stirring leaf 8 and scraper blade 13, wash feeder hopper 7, wash remaining material, later open stagnant water valve 16, with sewage through the outside of drain pipe 17 discharge feeder hopper 7 can.

Through setting up through-hole 40, movable block 41 and second blast pipe 43 in one side at material barrel 18 top, in the pivoted in-process of feeding screw 19, the gas is more easily dispersed in the molten material, the gas gets into second blast pipe 43 through first blast pipe 42, along with the gas increase, pressure increases, can jack-up movable block 41, compress second spring 45, the gas flows into in third blast pipe 44 through the space of jack-up movable block 41 with the inboard of second blast pipe 43, and outwards discharge through-hole 40, when gas pressure is insufficient, under the effect of second spring 45 elasticity, the movable block pushes down, block up second blast pipe 43, and the inclined lateral wall of second blast pipe 43 is added, the material that emits occasionally also can drop to feeding screw 19 soon, can not produce the material and block up the condition of first blast pipe 42.

Through at inside recess 35 and the ejector pad 36 that sets up of moving mould 2, and set up dead lever 1, fixed plate 37 and fixed block 39 in a riser 28 inboard, drive the shrink of piston rod 33 through cylinder 31 to drive moving mould 2 toward returning and withdrawing, when returning and withdrawing to a certain extent, fixed block 39 is hugged closely to one side of moving mould 2 inside, continues to return and withdraws, because first spring 38 is fixed, the fixed block can compress first spring 38 and promote ejector pad 36, makes the product drawing of patterns more easily.

The above only is the embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structures or equivalent processes of the present invention are used in the specification and the attached drawings, or directly or indirectly applied to other related technical fields, and the same principle is included in the protection scope of the present invention.
