Further, in inserting described in, be provided with one with described in a position-limitting pin arranged in a crossed manner of loosing core.
Further, described in insert and be provided with leader, described handle is positioned at described briquetting below.
Further, described counterdie is provided with a base, is provided with jacking block and bullet piece on described base, and a connecting rod is fixedly connected with described base through described bullet piece, is provided with the spring that described bullet piece is moved up and down on connecting rod.
Further, described briquetting is arranged on the front template of described patrix.
By above technical scheme, the utility model has following technique effect compared to prior art: demoulding link gear and injection mould of products die cavity are respectively two parts and independently exist separately, demoulding link gear and injection mold body move simultaneously, injection mould patrix drives briquetting interlock, realize the outer demoulding of injection molding part mould, saved original mould outside cylinder and loosed core, ensured that product ejects balance, strengthen the cool time of product, thereby ensured more distortion and the size of product.The terminal of simultaneously loosing core in cavity in product stripping process is not subject to External Force Acting, finished product terminal is smooth, with connector plastomer between the degree of eccentricity can be controlled in 0.15 ㎜, raising production efficiency, and improved the qualification rate of injection molding part.

Detailed description of the invention
By particular specific embodiment, embodiment of the present utility model is described below, person skilled in the art scholar can understand other advantages of the present utility model and effect easily by the disclosed content of this description.
Refer to Fig. 1 to Fig. 4.Notice, appended graphic the illustrated structure of this description, ratio, size etc., all contents in order to coordinate description to disclose only, understand and read for person skilled in the art scholar, not in order to limit the enforceable qualifications of the utility model, therefore the not technical essential meaning of tool, the adjustment of the modification of any structure, the change of proportionate relationship or size, do not affecting under effect that the utility model can produce and the object that can reach, all should still drop on the technology contents that the utility model discloses and obtain in the scope that can contain.Simultaneously, in this description, quote as " on ", the term of D score, " left side ", " right side ", " centre " and " " etc., also only for ease of understanding of narrating, but not in order to limit the enforceable scope of the utility model, the change of its relativeness or adjustment, changing under technology contents, when being also considered as the enforceable category of the utility model without essence.
As shown in Figure 3, view while being shown as the die sinking of the utility model mould, demoulding link gear of the present utility model comprises the movable insert on briquetting 7 and the counterdie being separately positioned on patrix, jacking block 6, movable insert comprises looses core 2, eject mold insert 4 and insert 3, loose core 2 with to eject mold insert 4 all parallel with the cavity of loosing core of moulded products 1, a loose core top of 2 is provided with the profile identical with the cavity of loosing core, a bottom of loosing core is connected to and inserts on 3, insert 3 bottom is provided with jacking block storage tank, the top, two sides of jacking block 5 is inclined-plane from top to down, , eject mold insert 4 through loosing core 2 and insert and 3 contact with inclined-plane.
Operating principle below in conjunction with the outer demoulding link gear of utility model injection mould is further described:
Goods injection mould, in the time of die opening state, inserts the terminal of loosing core (in order to the terminal 11 in moulded products 1 cavity) on request after movable insert entirety and puts it into and in die cavity, carry out mold-closing injection; After injection molding completes, operating personnel takes out together with movable insert moulded products 1 from die cavity, puts on demoulding link gear jacking block 5 (as shown in Figure 3).
