As a kind of preferred version: described mold insert includes base plate and is arranged at intervals at projection on the base plate, wherein, base plate and outer sleeve inwall fit tightly, and form up and down above-mentioned locating slot between the projection adjacent one another are, form vertical chute between the projection adjacent one another are of the left and right sides; Be provided with locating piece on the described locking plate, be provided with the opening that is complementary with locating piece on the inner sleeve outer wall, locating piece moves in above-mentioned chute and locating slot after being stretched out by opening.
As a kind of preferred version: described slot is the dovetail groove shape.
As a kind of preferred version: described slot has two and be symmetricly set on the outer sleeve, and the corresponding slot of mold insert also is two and is plugged in respectively in two slots.
As a kind of preferred version: described outer sleeve rear end is provided with one and is used for the limiting plate spacing to above-mentioned mold insert.
As a kind of preferred version: be provided with on the end face of described outer sleeve rear end for the fixing expansion pin of limiting plate, corresponding expansion pin is provided with through hole on limiting plate, and expansion pin is passed through hole and by the External Force Acting dilatancy limiting plate is fixed on the outer sleeve.
As a kind of preferred version: described flexible member is spring.
The utility model compared with prior art has obvious advantage and beneficial effect, particularly, as shown from the above technical solution, by on the inwall of outer sleeve rear end, along outer sleeve slot being set axially, mold insert is packed in the slot by the outer sleeve rear end, solve mold insert and be fixed in the mold insert that causes on the outer sleeve easily by coming off on the outer sleeve by the side, caused tapered end to damage, and manufacturing cost high problem.By this, the stabilized structure that the fixed structure of this mold insert can the Effective Raise tapered end, and then improve the stability of tapered end, and save cost, strengthen enterprise competitiveness.
For more clearly setting forth architectural feature of the present utility model and effect, be described in detail below in conjunction with accompanying drawing and specific embodiment.
