The inclined position 51 is provided with a waist-shaped hole 513 which passes through horizontally, and the limiting rod 53 is fixed on the lower mold 20 and inserted into the waist-shaped hole 513. The inclined position 51 is provided with an inclined top hole 512 which is connected to the waist-shaped hole 513 corresponding to the inclined top column 54, and the inclined top hole 512 is inclined toward the inner side of the inclined position 51, and the inclined top column 54 is movably arranged in the inclined top hole 512 and abuts against the limiting rod 53. The upper mold 10, the lower mold 20, the inclined position 51 and the inclined top column 54 together form an injection cavity for molding the product 100.
[0032] More specifically, the lower mold 20 is provided with a limiting hole 22 corresponding to the limiting rod 53 , and the limiting rod 53 is inserted into the limiting hole 22 .
[0033] When the mold is opened, the upper mold 10 drives the inclined guide column 40 to move upward, the sliding seat 30 drives the sliding guide rod 52 to move outward, and the inclined sliding position 51 moves downward along the inclined guide surface 5211 of the inclined guide portion 521. The inclined sliding position 51 moves along the length direction of the waist-shaped hole 513 through the cooperation between the limiting rod 53 and the waist-shaped hole 513, and the inclined ejector column 54 abutting on the limiting rod 53 moves toward the inner side of the inclined sliding position 51 to eject the product 100 in the injection cavity.
[0034] In this embodiment, the automatic demoulding mold with inclined ejector provided by the utility model has two slide seats 30 and four inclined ejector mechanisms 50. Two inclined ejector mechanisms 50 are mounted on one slide seat 30 in a mirror-symmetrical manner. Such an arrangement not only makes the structure of the automatic demoulding mold with inclined ejector compact, but also improves production efficiency. More specifically, one inclined ejector mechanism 50 includes an inclined slide 51, a slide guide rod 52, a limit rod 53 and a pair of inclined ejector columns 54. The pair of inclined ejector columns 54 are movably arranged in the inclined ejector holes 512 of the inclined slide 51, and the pair of inclined ejector columns 54 are relatively inclined toward the inner side of the inclined slide 51. This makes the product 100 more evenly stressed when the inclined ejector columns 54 eject the product 100, avoiding damage to the product 100 during demoulding, thereby improving the yield of the product 100.
[0035] From the above, the automatic demoulding mold with inclined ejector proposed in the utility model, through the cooperation of the inclined slide 51, the slide guide rod 52, the limit rod 53, the inclined ejector column 54, the lower mold 20, and the slide seat 30, and under the demoulding action of the upper mold 10, the inclined guide column 40 and the slide seat 30, not only has a simple structure, but also realizes automatic demoulding of the product 100, while avoiding damage to the product 100 during the demoulding process, thereby improving the yield of the product 100.

The inclined slider 51 is provided with an inclined guide hole 514 corresponding to the inclined guide portion 521 of the slider guide rod 52. The top wall of the inclined guide hole 514 is parallel to and abuts against the inclined guide surface 5211. The inclined slider 51 is slidably connected to the inclined guide surface 5211 through the inclined guide hole 514. When the slider seat 30 drives the slider guide rod 52 to move outwardly, the inclined slider 51 slides along the inclined guide surface 5211, and at the same time, the inclined slider 51 moves downwardly along the mounting hole 21, so that the inclined slider 51 is separated from the product 100.
[0037] More specifically, a limiting groove 5212 is provided on the inclined guide portion 521, and the inclined guide hole 514 is provided with a limiting protrusion 5141 corresponding to the limiting groove 5212. The limiting groove 5212 cooperates with the limiting protrusion 5141 to limit the movable range of the inclined position 51 on the inclined guide portion 521, so that the inclined guide hole 514 of the inclined position 51 is always in contact with the inclined guide surface 5211.
[0038] The slide guide rod 52 further has a connecting portion 522 , the upper surface of which is connected to the upper edge of the inclined guide surface 5211 , and the slide guide rod 52 is installed on the slide seat 30 via the connecting portion 522 . In this embodiment, the slider seat 30 is provided with a clamping groove 32, and the end of the connecting portion 522 is clamped in the clamping groove 32; more specifically, the clamping groove 32 is T-shaped and has a clamping protrusion 321, and the end of the connecting portion 522 is provided with an upper inclined groove 5221 and a lower inclined groove 5222 corresponding to the clamping groove 32, and the upper inclined groove 5221 and the lower inclined groove 5222 are respectively abutted against the clamping protrusion 321, so that the slider guide rod 52 is clamped on the slider seat 30 to realize that the slider guide rod 52 follows the movement of the slider seat 30, and the slider guide rod 52 is tilted to achieve cooperation with the inclined guide hole 514 of the inclined slider 51.
[0039] More specifically, the lower mold 20 is provided with a movable hole 23 corresponding to the connecting portion 522 , and the sliding guide rod 52 is movably disposed in the movable hole 23 .
[0040] See also Figure 6-Figure 9 and Fig.12 The inclined position 51 has a protruding portion 511, and the protruding portion 511 is provided with an inclined top groove 5111. The inclined top groove 5111 is connected to the inclined top hole 512. The inclined top column 54 is movably arranged in the inclined top groove 5111 and the inclined top hole 512. The protruding portion 511, the inclined top column 54, the upper mold 10, and the lower mold 20 together surround the injection cavity. When the inclined position 51 moves downward to disengage from the product 100, the inclined top column 54 relatively protrudes from the inclined top groove 5111 and moves horizontally along the inclined direction of the inclined top groove 5111. The inclined top column 54 disengages from the edge of the product 100 and gradually abuts against the center of the lower surface of the product 100 to eject the product 100.
[0041] The inclined ejector column 54 is provided with a slot 541 corresponding to the limiting rod 53, and the limiting rod 53 is movably disposed in the slot 541. When the inclined position 51 moves downward to disengage from the product 100, the inclined ejector column 54 abuts against the limiting rod 53 through the slot 541, so that the inclined ejector column 54 moves upward relative to the inclined position 51 to eject the product 100.
[0042] The utility model has the beneficial effects of a mould with an inclined top and automatic demoulding: not only is the structure simple, but also the automatic demoulding is realized, thereby improving the product yield.
