Specific embodiment

Referring to FIG. 1, FIG. 2 and FIG. 3, a kind of inner slide demoulding mechanism of the utility model, including front cavity 1, rear cavity 2, Preceding mould mold insert 3, type core 4, sliding block 5 and inner slide stripper apparatus are provided with through-hole and sprue gate 11 in the front cavity 1, described Type core 4 is embedded between front cavity 1 and rear cavity 2, the through-hole that the preceding mould mold insert 3 passes through front cavity 1 is pressed on type core 4, described Sliding block 5 is looped around around type core 4, and the sliding block 5 includes slide block insert 51 and outer slide 52, mould mold insert before slide block insert 51 cooperates 3,1 shape forming cavity of type core 4 and front cavity, outer slide 52 and front cavity 1, rear cavity 2 are fitted close, and the rear cavity 2 is provided with Through-hole, several inner slide stripper apparatus are provided in the type core 4, and the inner slide stripper apparatus includes the edge with convex sliding slot Part 62 and mold insert 61 with concave slide groove, the mold insert 62 with convex sliding slot are slidably mounted on the cunning of the mold insert 61 with concave slide groove In slot, there is countersunk head portion 621, the countersunk head portion 621 is affiliated to the countersunk head in rear cavity 2 below the mold insert 62 with convex sliding slot It gives up the throne on slot 21, is provided with product overhead kick hole 622 above the mold insert 62 with convex sliding slot.

The utility model is inlaid with sliding block 5 between front cavity 1 and rear cavity 2, and inner slide demoulding is provided in type core 4 Device, including the mold insert 62 with convex sliding slot and the mold insert 61 with concave slide groove, 62 lower end of the mold insert setting with convex sliding slot There is the countersunk head portion 621 for preventing mold insert from deviating from from mode, upper end is provided with the product overhead kick hole 622 with product cooperation.It is being molded After the completion of molding, referring to Fig. 4, since space is smaller between product and type core 4, without the space of oblique top movement, need to be arranged interior Sliding block stripper apparatus is demoulded.After front cavity 1, rear cavity 2 are opened, the outer cunning that is embedded between front cavity 1 and rear cavity 2 Block 52 falls off, and the slide block insert 51 being looped around around type core 4 also falls off therewith；Subsequent rear mold moves backward, drives and has recessed cunning The mold insert 61 of slot moves backward, with concave slide groove mold insert 61 pulling function, the mold insert 62 with convex sliding slot be pulled to Medial motion, the product in product overhead kick hole 622 are separated with the mold insert 62 with convex sliding slot, deviate from the overhead kick on the inside of product, most Whole realization product is automatically disengaged with type core 4, is realized the normal demoulding of product, is improved production efficiency.

In the present embodiment, several air discharge ducts are provided in the front cavity 1.Several exhausts are provided in front cavity 1 Slot realizes sufficiently exhaust, avoids the occurrence of lack of fill, the bad problem of exhaust such as surface is burnt.

It is provided with inlay in the front cavity 1, rear cavity 2 as an embodiment of the present embodiment referring to Fig. 3, The slide block insert 51 and outer slide 52 are embedded between front cavity 1, rear cavity 2.Slide block insert 51 and type core 4, preceding mould mold insert 3 Type chamber is collectively formed with the cooperation of front cavity 1, outer slide 52 is embedded between front cavity 1 and rear cavity 2, to mould mold insert before being looped around The slide block insert 51 of 3 surroundings is fixed, and guarantees that the positional relationship between mold insert is correct.

Referring to Fig. 4 and Fig. 5, in the present embodiment, the mold insert 61 with concave slide groove and the edge with convex sliding slot The coincidence face of part 62 has 5 degree of inclination angle.Setting inclination angle enables product overhead kick to deviate from from product overhead kick hole 622.In this reality It applies in example, tilt angles are set as 5 degree.In the remaining embodiments, when the depth in product overhead kick hole 622 is deeper, incline accordingly Angle angle is set as biggish numerical value, and the distance that the mold insert 62 with convex sliding slot moves inwardly increases, and it is deeper to deviate from depth Product overhead kick.Fig. 4 depends on the movement of rear mold due to the movement of the mold insert 61 with concave slide groove, and increasing die sinking amount can also improve The ability of inner slide stripper apparatus abjection overhead kick.

Referring to Fig. 5, in the present embodiment, the mold insert 62 with convex sliding slot has countersunk head portion 621 and product overhead kick hole 622, the countersunk head portion 621 is 3mm into the give up the throne depth of slot 21 of countersunk head, and the depth in product overhead kick hole 622 is 0.38mm. When rear mold drives the mold insert 61 with concave slide groove to draw back, since the depth in product overhead kick hole 622 only has 0.38mm, having The pulling function of the mold insert 61 of concave slide groove, the mold insert 62 with convex sliding slot move inwardly, and the overhead kick of product can be from product overhead kick Deviate from hole 622, realizes the disengaging of product and type core 4.

The above specific structure and dimension data are illustrated to the preferred embodiment of the utility model, but this reality It is not limited to the specific embodiments with novel creation, those skilled in the art are in the premise without prejudice to the spirit of the present invention Various equivalent deformation or replacement can be also made down, these equivalent deformations or replacement are all contained in the claim of this application and are limited In fixed range.
