In addition, the descriptions related to "first", "second", etc. in the present invention are only for description purposes, not specifically referring to the order or sequence, and are not intended to limit the present invention, but only to distinguish the components or operations described in the same technical terms, and are not to be construed as indicating or implying any relative importance or implicit indication of the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions in the embodiments may be combined with each other, but it must be based on the realization of those skilled in the art, and when the technical solutions are contradictory or cannot be realized, the combination of the technical solutions should not be considered to exist, and is not within the protection scope of the present invention.

The utility model discloses a make things convenient for mould of feed head clearance, including last mould 1 and lower mould 2, it forms die cavity 3 to go up between mould 1 and the lower mould 2, the top of going up mould 1 is provided with through-hole 11, the upper portion of through-hole 11 is provided with the annular step 12 of outside expansion, insert in the through-hole 11 and be equipped with feed head 4, be provided with outside annular chimb 41 on the outer wall of feed head 4, annular chimb 41 is located annular step 12 top, it is equipped with sealing washer 5 to inlay between annular chimb 41 and the annular step 12, the opening part threaded connection of annular step 12 has the pressure cover 6 that is used for compressing tightly annular chimb 41, stretch out outside pressure cover 6 after pressure cover 6 is run through to the upper end of feed head 4, be provided with a plurality of antiskid.

An annular groove 42 for partially embedding the sealing ring 5 is formed in the lower end face of the annular convex edge 41, and the lower end of the sealing ring 5 extends out of the annular groove 42; after adopting this kind of structure, one can realize the location to the sealing washer, two can make the sealing washer effectively avoid outside expansion, push away annular chimb at the pressure cover promptly for when annular chimb compresses tightly the sealing washer on annular step, can improve the seal strength between annular chimb and the annular step.

The outer diameter of the annular flange 41 is smaller than the inner diameter of the annular step 12; after adopting this kind of structure, when assembling the feed head to last mould or taking out the feed head from last mould, can avoid producing the friction between the inner wall of annular chimb and annular step, so, can assemble the feed head to last mould or take out the feed head from last mould more conveniently.
