The terms "first", "second", and the like used in the specification and the claims of the present application and the above drawing description are intended to distinguish different objects, not to describe a particular order.

[0041] Reference to“an embodiment” herein means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase“in

[0042] Referring to Figures 1-4 As shown in the drawings, the embodiment of the application provides a slant hole demolding device, which comprises a bottom plate 1, a bearing mechanism 2 and a slant hole demolding mechanism 3.

[0043] In some embodiments, the bearing mechanism 2 is arranged on the bottom plate 1, and the bearing mechanism 2 is used for bearing a mold 8. In this embodiment, the bearing mechanism 2 is arranged on the bottom plate 1 and fixed on the bottom plate 1 by fixing bolts.

[0044] In some embodiments, the slant hole demolding mechanism 3 is movably arranged on the bearing mechanism 2, and the slant hole demolding mechanism 3 comprises a first movable mold plate 31, a second movable mold plate 32 and at least one set of slant hole demolding components 33. The first movable mold plate 31 is detachably arranged on the bearing mechanism 2, the second movable mold plate 32 is movably arranged on the first movable mold plate 31, and the slant hole demolding components 33 are arranged between the first movable mold plate 31 and the second movable mold plate 32. The second movable mold plate 32 is movable relative to the first movable mold plate 31, so that the slant hole demolding components 33 are movable along the extension direction of the slant hole of the mold 8, for slant hole core-pulling demolding of the mold 8.

[0045] When the slant hole demolding mechanism 3 is docked with the bearing mechanism 2, a mold cavity 4 is formed between the slant hole demolding mechanism 3 and the bearing mechanism 2, and the mold cavity 4 is used for preparing and accommodating the mold 8.

[0046] In this embodiment, before injection molding is performed in the mold cavity 4, the second movable mold plate 32 moves towards the first movable mold plate 31, and the slant hole demolding components 33 are at least partially placed in the mold cavity 4. When the mold 8 is injection molded in the mold cavity 4, a slant hole is formed at the contact position between the mold 8 and the slant hole demolding components 33, and then the second movable mold plate 32 moves away from the first movable mold plate 31, and the slant hole demolding components 33 are separated from the mold cavity 4, so as to realize core-pulling of the slant hole on the mold 8.

[0047] The inclined hole demolding device provided by the embodiment of the present application is provided with an inclined hole demolding mechanism 3. The relative movement between a first movable mold plate 31 and a second movable mold plate 32 drives the movement of the inclined hole demolding assembly 33, so as to form an inclined hole during the injection molding of the mold 8, and to perform core pulling on the inclined hole on the mold 8 after molding, so as to facilitate the demolding of the inclined hole of the mold 8. The demolding mode is simple, and the problem of the injection molding of the inclined hole of the mold 8 is solved.

The guide groove has a first end close to the cavity 4 and a second end away from the cavity 4. The limiting protrusion 3311 is arranged at the second end.

[0051] In some embodiments, the sliding block 332 is movably arranged in the guide groove. In this embodiment, a sliding block 332 needle is arranged on the side of the sliding block 332 close to the cavity 4. The sliding block 332 needle is arranged in the through hole and can move along the through hole. When the sliding block 332 moves to the first end along the guide groove, the sliding block needle 335 is at least partially arranged in the cavity 4, so as to form an inclined hole at the sliding block needle 335 during the injection molding of the mold 8. When the sliding block 332 moves to the second end along the guide groove, the sliding block needle 335 exits the cavity 4, so as to perform core pulling on the inclined hole on the mold 8, and facilitate the demolding of the inclined hole of the mold 8.

[0052] In some embodiments, the elastic piece 333 is connected between the groove wall of the V-shaped groove and the side wall of the sliding block 332 close to the through hole. The arrangement of the elastic piece 333 facilitates the movement of the sliding block 332 to the second end of the guide groove under the action of no external force, so that the sliding block needle 335 exits the cavity 4.

[0053] In some embodiments, the inclined wedge 334 is fixed on the second movable die plate 32, and the inclined wedge 334 is at least partially arranged in the mounting groove, in the present embodiment, the inclined wedge 334 forms a surface contact with the guide, and the slider 332 is tightly attached to the inclined wedge 334 under the elastic reset action of the elastic member 333.

[0054] In the present embodiment, when the second movable die plate 32 moves towards the first movable die plate 31, the inclined wedge 334 pushes the slider 332 to move along the guide groove to the first end, the slider pin 335 moves along the through hole, and the end of the slider pin 335 is arranged in the cavity 4, as shown in Figure 4 When the second movable die plate 32 moves away from the first movable die plate 31, the elastic member 333 pushes the slider 332 to move along the guide groove to the second end, and under the limiting action of the limiting block 3311, the maximum movement distance of the slider 332 is limited, the slider pin 335 moves along the through hole, and the end of the slider pin 335 exits the cavity 4, as shown in Figure 5 .

[0055] The embodiment of the present application realizes that the slider pin 335 of the slider 332 is separated from the cavity 4 by controlling the movement of the second movable die plate 32 relative to the first movable die plate 31, so as to realize the core pulling of the inclined hole of the mold 8, so as to facilitate the demolding of the inclined hole of the mold 8, and the demolding mode is simple and fast; in addition, the limiting member 331 is arranged, which can not only limit the slider 332, but also form a sliding groove with the V-shaped groove, and guide the slider 332.

[0057] The embodiment of the present application further arranges the stop member 34 to realize the guiding of the second movable die plate 32 and the limiting of the displacement distance of the second movable die plate 32 relative to the first movable die plate 31, so as to realize the limiting of the relative displacement distance of the slider 332 in the guide groove, and then realize the control of the movement distance of the slider pin 335 along the through hole, which plays a role in controlling the depth of the inclined hole during injection molding, and plays a role in core pulling and demolding of the inclined hole during demolding.

[0058] In the embodiment, the stopper 34 is a plug screw, wherein the plug screw comprises a threaded section 341, a light rod section 342 and a stop screw cap 343 connected in sequence; the threaded section 341 is threadedly connected with a threaded hole on the first movable mold plate 31; the stop end of the plug screw is the stop screw cap 343; the second movable mold plate 32 is sleeved on the light rod section 342 and is movable between the stop screw cap 343 and the threaded section 341.
