The power part on the injection molding machine drives the inclined pin 3 in the two guide holes I, the front inclined moving die plate III 25 and the front inclined moving die plate II 21 to move obliquely downwards together, drives the inclined pin 3 of the two guide holes II, the rear inclined moving die plate IV 26 and the rear inclined moving die plate III 22 to move obliquely downwards together, and vertically moves the moving die plate I20, the left vertical moving die plate I23 and the right vertical moving die plate II 24 to vertically move downwards under the guiding action of the guide post 13 and the guide sleeve 14 until the moving die plate 2 is pressed on the fixed die plate 4, and a teacup cover pouring cavity is formed between a teacup cover lower punch and a teacup cover upper die cavity.
The reset of the push plate 9 after the product is pushed out is realized by virtue of the reset rod 11, the inclined pin 3 plays a side core pulling role, the Z-shaped head at the top of the pull rod 17 can hook the coagulated material separated from the sprue bush 16 and the sub-runner, the coagulated material is left on the fixed die plate 4 along with the product, and the pull rod 17 is fixed on the push plate 9, so that the coagulated material and the pull rod 17 are pushed out of the die by the push mechanism, and the product can be taken down from the pull rod 17 together with the coagulated material after the die is opened; the spacing nail 18 makes the push pedal 9 produce the space with cover half bedplate 7 between to dirty the deposit, avoid hindering the normal action of push pedal 9 and reset, and the returnable position of push rod 15 is controlled to the head thickness of accessible regulation spacing nail 4 simultaneously, and the temperature of injection mould to the plastics fuse-element in the mould is about 200 ℃, and the temperature of plastic part when taking out from the mould die cavity is below 60 ℃, and the reduction of temperature relies on letting in cooling water and takes away the heat in the mould.
Finally, it is noted that the above embodiments are only for illustrating the technical solution of the present invention and not for limiting the same, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications and equivalents may be made thereto without departing from the spirit and scope of the technical solution of the present invention, which is intended to be covered by the scope of the claims of the present invention.
