Detailed Description
In order to make the above objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, as those skilled in the art will be able to make similar modifications without departing from the spirit and scope of the present invention.
As shown in fig. 1-4, the utility model provides an in-mold cutting ejecting device for mould, the in-mold cutting ejecting device includes:
the mounting seat 1 is matched with a mold cavity of the mold, and a cutting groove 11 matched with an injection opening of the mold cavity is formed in the mounting seat 1;
the bottom end of the cutter 2 is fixed on the lower ejector plate 5 of the die, the top end of the cutter 2 penetrates through the upper ejector plate 6 of the die and then is inserted into the cutting groove 11, and when the cutter 2 moves upwards, the joint of the injection opening and the product 4 can be cut off; and
the bottom end of the ejector pin 3 is fixed on the upper ejector pin plate 6, and the top end of the ejector pin 3 is inserted into the die cavity, so that the product 4 can be ejected after the cutter 2 is cut off.
Specifically, the present embodiment is directed to a side gate type mold. A side wall of the mounting seat 1 facing the cavity is provided with a cutting groove 11, and the cutting groove 11 penetrates up and down. The bottom mounting of cutter 2 is on thimble board 5 down, and in cutter head of cutter 2 inserted grooving 11 from up down, cutter 2 can be along grooving 11 up-and-down motion, and grooving 11 has a limiting displacement to cutter 2 simultaneously, avoids cutter 2 to take place to rock, ensures that cutter 2 locates the position and does not have the error.
