DETAILED DESCRIPTION

[0023] The technical scheme in the embodiments of the utility model will be apparently and completely described in connection with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor fall within the protection scope of the utility model.

[0025] The upper portion of inner groove 2 is set up with recess 8, and recess 8 is installed with mould 9 in the inside, and the lower surface of mould 9 is installed with backing plate 10, and the lower surface of mould 9 is set up with several groups of circular hole 11 corresponding to top rod 6, and the top of every group of top rod 6 is connected to the lower surface of backing plate 10 through corresponding circular hole 11.

[0026] As preferred, the inner part of the inner groove 2 is provided with support columns 12 on both sides of the cylinder 3, and each group of support columns 12 is provided with a spring 13 in the middle. The support columns 12 in the inner groove 2 support the bottom plate 4. After the plastic part is formed, the cylinder 3 in the inner groove 2 pushes the bottom plate 4 upwards, thereby pushing the ejector rod 6 on the bottom plate 4 to move upwards in the circular hole 11 at the bottom of the mold 9, so that the pad 10 on the ejector rod 6 moves upwards, and the plastic part on the pad 10 is pushed to the upper surface of the lower base 1, facilitating the subsequent taking of the plastic part. After the plastic part is taken, the cylinder 3 drives the bottom plate 4 to move, and when the bottom plate 4 abuts against the support column 12, the cylinder 3 stops moving, so that the pad 10 can be returned to the original position. The support plate 12 can support the bottom plate 4 when the bottom plate 4 moves downwards, preventing the bottom plate 4 from continuously falling downwards and affecting the pad 10, which may cause damage to the plastic part.
