In present embodiment, this pin groove 2823 is in substantially l shape.This pin groove 2823 has the first pushing surface 2825 and second and pushes Face 2826.This first pushing surface 2825 and the second pushing surface 2826 be connected and between the angle that formed be more than 90 degree.This thimble The substantially t-shaped shape of groove 2824.This thimble groove 2824 has the 3rd pushing surface 2827 and the 4th pushing surface 2828.4th pushing surface 2828 and the 3rd pushing surface 2827 be connected and between the angle that formed be more than 90 degree, and with this first pushing surface 2825 and the Angle between two pushing surfaces 2826 is equal.This first pushing surface 2825 is parallel with the 3rd pushing surface 2827.This second pushes Face 2826 is parallel with the 4th pushing surface 2828.During injection matched moulds, the first pushing surface 2825 and the second pushing surface 2826 are closer The edge of this side towards this cavity plate 242 for pin body 2821, the 3rd pushing surface 2827 and the 4th pushing surface 2828 are relatively Edge away from this side towards this cavity plate 242 for pin body 2821.One slit 2829 is additionally provided with this thimble groove 2824. This slit 2829 is relative with the 3rd pushing surface 2827 and the 4th pushing surface 2828.
This acceleration ejecting mechanism 28 each also includes rotating shaft 284.This rotating shaft 284 is arranged in this axis hole 2822, and two ends It is arranged in the first push pedal 262 so that this insert body 2821 can rotate in the range of certain angle around this rotating shaft 284.Can manage Solution, in other embodiments, if this insert body 2821 can be articulated in the first push pedal 262 by another way, For example, this insert body 2821 is provided with protruding shaft, then this rotating shaft 284 and axis hole 2822 can omit.
This acceleration ejecting mechanism 28 each also includes pin 286.One end of this pin 286 is contained in this pin groove 2823 And by thrust in this second push pedal 264, the other end passes through this second push pedal 264 and stretches out.Specifically, this pin 286 is substantially T-shaped shape.Specifically, this pin 286 has one first push stopping part 2862.This pin 286 has the one of the first push stopping part 2862 End is offseted with this first pushing surface 2825 or the second pushing surface 2826.It is correspondingly arranged on pin hole in this second push pedal 264 2642.The other end of this pin 286 may pass through this pin hole 2642 and stretches out, and this first push stopping part 2862 thrust in this second In push pedal 264.
This acceleration ejecting mechanism 28 each also includes thimble 288.One end of this thimble 288 is contained in this thimble groove 2824 And by thrust on this insert body 2821, the other end passes through this molding assembly 24 and pushes on the surface of a product 200.Tool Body ground, the substantially t-shaped shape of this thimble 288.This thimble 288 has one second push stopping part 2882.This thimble 288 has this second to be stopped One end of pushed section 2882 is offseted with the 3rd pushing surface 2827 or the 4th pushing surface 2828.The other end of this thimble 288 passes through After this slit 2829, continue across the side that this second push pedal 264, cavity plate 242 and core 244 pusher peak at product 200 On.The width of this slit 2829 is of substantially equal with the external diameter of this thimble 288, as long as this thimble 288 removes its second push stopping part 2882 External enwergy passes through this slit 2829.This slit 2829 plays guide effect to the activity of this thimble 288.
Please also refer to Fig. 5 and Fig. 6, during mold-closing injection, the first push stopping part 2862 of this pin 286 pushes first supports in this In pushing surface 2825, the second push stopping part 2882 of this thimble 288 pushes on the 3rd pushing surface 2827.When injection completes, should Dynamic model 10 is away from this cover half 20.Ejection assembly 26 is driven beginning action.First, at least one this acceleration ejecting mechanism 28 is with this First push pedal 262 is together with the motion of the second push pedal 264 to the lateral movement near this cavity plate 242, the freedom of this pin 286 End is offseted with this cavity plate 242 first.When this pin 286 pushes on this molding assembly 24, this insert body 2821 passes through This thimble 288 is accelerated to eject by lever principle, and this thimble 288 is thus able to make this product 200 demoulding.Specifically, this cavity plate The deboost of 242 pairs of this pins 286 force this pin body 2821 to rotate around this rotating shaft 284 so that this pin 286 gradually Slide on the second pushing surface 2826, this pin groove 2823 thus be gradually distance from this cavity plate 242, this thimble 288 gradually slides to On four pushing surfaces 2828, this thimble groove 2824 thus near this cavity plate 242, now this second push pedal 264 pushes in cavity plate On 242.This thimble groove 2824 thus promote this thimble 288 quickly to stretch out and by the projection 202 of product 200 from this projection curved lever In 246 forming tank 2462 deviate from, this product 200 thus drop.It is understood that backhaul is contrary with above-mentioned action, no longer superfluous herein State.
The ejection assembly 26 of this injection mold 100 increased acceleration ejecting mechanism 28, thus increased ejection assembly 26 Ejection stroke, so that the projection 202 of product 200 smoothly can be deviate from from the forming tank 2462 of this projection curved lever 246, solves After product 200 molding cannot the smooth demoulding problem.
Those skilled in the art are it should be appreciated that above embodiment is intended merely to illustrate that this practicality is new Type, and be not used as being to restriction of the present utility model, as long as within spirit of the present utility model, to above reality The suitable change that the mode of applying is made and change all fall within the scope of this utility model claims.
