[0024] In this embodiment, two electric push rods 4 are respectively located on opposite sides of the mold frame body 2. When the mold needs to be opened after the product is injection molded, the electric push rods 4 work to drive the upper mold 3 to move upward, and the product adheres to the bottom surface of the upper mold 3 and moves upward together. Then, the ejector pin in the upper mold 3 works to push the product down. This process is a prior art and will not be described in detail here.

[0025] After the upper mold 3 moves upward for a distance, it will drive the sliding plate 7 to move toward the mold frame body 2 through the linkage part 11. The sliding plate 7 drives the guide plate 9 to partially move between the upper mold 3 and the mold frame body 2, and then the ejector pin works to push the product down. The product falls directly to the top of the guide plate 9 and slides along the top surface of the guide plate 9 into the collection box 10, thereby automatically realizing the collection of the product.

[0026] Then the electric push rod 4 moves in the reverse direction, the guide plate 9 returns to its original position, and the upper die 3 also returns to its original position. The upper die 3 does not contact the guide plate 9 during the movement.

[0027] In a further preferred embodiment of the present invention, Figure 2 As shown, the linkage part 11 includes two springs 111 fixedly connected to the bottom of the top plate 6, the bottom ends of the two springs 111 are commonly fixedly connected to an upper plate 112, the upper plate 112 is located directly above the upper mold 3, a sliding bar 113 is provided on one side of the upper plate 112, a sliding member 114 is provided above the sliding bar 113, and two first rods 115 are hinged on the side wall of the upper plate 112, one end of the first rod 115 away from the upper plate 112 is hinged to the sliding bar 113, and two second rods 116 are hinged to the bottom end of the sliding bar 113, and the bottom end of the second rod 116 is hinged to the top surface of the sliding plate 7.

[0028] In this embodiment, the upper mold 3 moves upward until it contacts the upper plate 112 and drives the upper plate 112 to move upward, the spring 111 is compressed, the upper plate 112 drives the first rod 115 to move, the first rod 115 drives the sliding bar 113 to slide, the sliding bar 113 drives the second rod 116 to move, and the second rod 116 drives the sliding plate 7 to move horizontally toward the mold frame body 2.

[0029] In the initial state, there is a gap between the upper plate 112 and the upper mold 3 , so when the upper mold 3 moves upward for a certain distance, the guide plate 9 will move toward the mold frame body 2 to ensure that the guide plate 9 does not collide with the upper mold 3 .

[0030] In a further preferred embodiment of the present invention, Figure 2 As shown, the guide plate 9 is arranged to be inclined downward on a side away from the mold frame body 2 .

[0031] In this embodiment, the products falling onto the top of the guide plate 9 can slide quickly and stably and fall into the collection box 10 , preventing the products from accumulating on the guide plate 9 .

[0032] In a further preferred embodiment of the present invention, Figure 2 As shown, baffles 12 are fixedly connected to the top of the guide plate 9 near both sides.

[0033] In this embodiment, the products falling on the top of the guide plate 9 are blocked by the baffle 12 and will not fall from the width direction of the guide plate 9 , but can only move along the length direction of the guide plate 9 and fall into the collection box 10 .

[0034] In a further preferred embodiment of the present invention, Figure 3As shown, the limiting portion 8 includes two sliding grooves 81 opened at the top of the base plate 1, and a fixed rod 82 is horizontally fixedly connected in the sliding groove 81. Two sliding blocks 83 are fixedly connected to the bottom end of the sliding plate 7. The lower half of the sliding block 83 is slidably connected in the corresponding sliding groove 81, and the sliding block 83 is slidably connected to the corresponding fixed rod 82.

[0035] In this embodiment, the sliding block 83 can only slide along the extending direction of the fixing rod 82, thereby ensuring that the sliding plate 7 can only slide horizontally.

[0036] In a further preferred embodiment of the present invention, Figure 3 As shown, the sliding member 114 includes a wedge-shaped groove 1141 opened at the bottom of the top plate 6 , and a wedge-shaped bar 1142 is fixedly connected to the top of the sliding bar 113 , and the wedge-shaped bar 1142 is slidably connected in the corresponding wedge-shaped groove 1141 .

[0037] In this embodiment, the wedge block is an inverted trapezoidal setting, and the side wall of the wedge block fits with the inner wall of the corresponding wedge groove 1141, so the wedge block can only slide horizontally and will not fall, ensuring that the sliding bar 113 can only move horizontally.

[0038] In a further preferred embodiment of the present invention, Figure 2 As shown, a plurality of sleeves 13 are fixedly connected to the bottom of the top plate 6 , a plurality of slide bars 14 are fixedly connected to the top of the upper plate 112 , and the upper half of the slide bars 14 are slidably connected to the corresponding sleeves 13 .

[0039] In this embodiment, the sleeve 13 and the slide rod 14 cooperate to ensure that the upper plate 112 can only move vertically, thereby ensuring that the upper mold 3 can drive the sliding plate 7 to move toward the mold frame body 2 when moving upward.

[0040] The implementation principle of the above embodiment is:

[0041] When the product needs to be opened after injection molding, the electric push rod 4 works to drive the upper mold 3 to move upward, and the product adheres to the bottom surface of the upper mold 3 and moves upward together. After the upper mold 3 moves a certain distance, it contacts the upper plate 112 and drives the upper plate 112 to move upward. The spring 111 is compressed, and the upper plate 112 drives the first rod 115 to move, the first rod 115 drives the sliding bar 113 to slide, the sliding bar 113 drives the second rod 116 to move, and the second rod 116 drives the sliding plate 7 to move horizontally toward the mold frame body 2. The sliding plate 7 drives the guide plate 9 to move partly between the upper mold 3 and the mold frame body 2, and then the ejector works to push the product down, and the product falls directly to the top of the guide plate 9, and slides along the top surface of the guide plate 9 into the collection box 10, thereby automatically realizing the collection of the product.

[0042] Then the electric push rod 4 moves in the reverse direction, and under the restoring force of the spring 111, the guide plate 9 returns to its original position, and then the upper mold 3 also returns to its original position.

[0043] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
