Referring to fig. 5 and 6, in the present embodiment, the horizontal row-position diagonal-drawing demolding mechanism includes a base 4, a linear driving mechanism 5, a mounting seat assembly 6, a front mold 2, and a rear mold 3.

Wherein, the front mould 2 is provided with a slot 201 with an opening aligned with the rear mould 3; after the rear mold 3 is inserted into the slot 201, a mold cavity matched with the cover type product 1 in shape can be formed with the front mold 2. The rear die 3 comprises a slide insert 301 and slide inclined tops 302 positioned at two sides of the slide insert 301.

The front die 2 is tightly installed at the front end of the base 4, and the linear driving mechanism 5 is installed at the rear end of the base 4; the middle part of the base 4 is provided with a guide sliding groove 401, and the mounting seat assembly 6 and the rear die 3 are both positioned in the guide sliding groove 401. The row position insert 301 is fastened on the mounting seat assembly 6, and the row position pitched tops 302 on two sides are connected with the row position insert 301 in a sliding manner.

The driving end of the linear driving mechanism 5 is connected to the mounting seat assembly 6, and the rear mold 3 can be driven to slide forward along the guide sliding groove 401 through the mounting seat assembly 6, so that the rear mold 3 is inserted into the slot 201 of the front mold 2, or the rear mold 3 can be driven to slide backward along the guide sliding groove 401, so that the rear mold 3 is extracted from the slot 201 of the front mold 2.

In this embodiment, the cover product 1 is provided with a fixing boss 102 inside. The side surface of the row position inclined top 302, which is far away from the row position insert 301, is provided with an abdicating groove 3021 communicated with the mold cavity, and after the sizing material in the abdicating groove 3021 is cured, the fixed boss 102 can be formed.

In this embodiment, a distance between the two row-position inclined tops 302 gradually decreases toward a direction close to the bottom of the slot 201, specifically, the row-position insert 301 is in an isosceles trapezoid structure, and each row-position inclined top 302 is disposed corresponding to a waist position 3011 of the row-position insert 301. Referring to fig. 7, a guide boss 3012 is provided on the side surface (i.e. waist position 3011) of the slide insert 301; the slide lifter 302 is provided with a dovetail groove for the guide boss 3012 to insert into and be connected with the guide boss 3012 in a sliding manner.

The horizontal slide oblique-drawing demoulding mechanism provided by the embodiment has the following working process:

s10: referring to fig. 8, the linear driving mechanism 5 inserts the rear mold 3 into the front mold 2 in the X-axis forward direction;

s20: injecting glue into the die cavity, and curing the glue to obtain the cover cap product 1 with the built-in fixed boss 102;

s30: the linear driving mechanism 5 reversely extracts the rear die 3 along the X axis;

specifically, step S30 may be refined as the following process:

s301: referring to fig. 9, when the linear driving mechanism 5 retracts in the reverse direction along the X axis, the slide insert 301 firstly retracts in the reverse direction along the X axis out of the slot 201, and the slide inclined tops 302 at both sides cannot be displaced along the X axis at the first moment due to the limitation of the fixing boss 102, and can only slide relative to the slide insert 301 under the guiding action of the guiding boss 3012;

s302: however, since the row position insert 301 gradually narrows toward the front mold 2, the two rows of inclined tops 302 will also displace in the Y-axis direction while sliding relative to the row position insert 301, specifically, the two rows of inclined tops 302 will approach each other;

s303: referring to fig. 10 and 11, when the displacement distance dimension of the row-position lifter 302 in the Y-axis direction is greater than the protruding dimension of the guide boss 3012 (i.e. the groove depth dimension b of the relief groove 3021), the fixing boss 102 no longer obstructs the movement of the row-position lifter 302 in the X-axis direction, the two row-position lifters 302 are drawn out of the slot 201 of the front mold 2 along with the row-position insert 301, and the cover lid type product 1 remains in the slot 201 of the outer mold, thereby completing the demolding operation of the rear mold 3; further, in order to ensure that the size of the movable space of the slide lifter 302 in the Y-axis direction is greater than the protruding size of the guide boss 3012, the width dimension a of one end of the slide insert 301 close to the bottom of the slot 201 may be set to be more than twice the depth dimension b of the relief slot 3021;

s40: and taking the cover cap product 1 out of the slot 201 to complete the whole injection molding process.

Optionally, linear drive mechanism 5 can be cylinder, pneumatic cylinder or motor lead screw subassembly etc. the utility model discloses do not do the injecing to this.

To sum up, the utility model provides a horizontal position of going is taken out demoulding mechanism to one side cuts apart into the width and narrows down gradually the position mold insert 301 of going and two can move position mold insert 301 relatively and carry out interior gliding row position lifter 302, when going position mold insert 301 outward taking out, two row position lifters 302 can slide and be close to each other along position mold insert 301 of going, and then break away from fixed boss 102, realize the drawing of patterns operation to built-in fixed boss 102's shroud class product 1 from this, improve production efficiency.
