DETAILED DESCRIPTION

[0029] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only the parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0030] like Figure 1 As shown, the present invention provides a molding die for a plastic accessory for a vehicle, comprising a support seat 1, a cylinder 4 and a slide plate 7. The support seat 1 is installed at the middle of the top surface of the bottom plate 2, and a fixed mold 3 is arranged on the top of the support seat 1. The cylinder 4 is locked with the top plate 5 for support, and the piston rod at the bottom of the cylinder 4 passes through the top surface of the top plate 5 and is connected to the slide plate 7. A hollow column 6 for auxiliary support is installed at each of the four ends of the bottom of the top plate 5. The hollow column 6 passes through the edge of the top surface of the slide plate 7 and is fastened to the edge of the top surface of the bottom plate 2. The slide plate 7 slides up and down along the hollow column 6. A movable mold 10 matched with the fixed mold 3 is arranged at the bottom of the slide plate 7.

[0031] Furthermore, the fixed mold 3 is connected to the top of the support base 1 through the mounting mechanism 86, and the mounting mechanism 86 at the bottom of the fixed mold 3 and the mounting mechanism 86 at the top of the movable mold 10 are separately arranged, so that the fixed mold 3 can be mounted on the support base 1 through the mounting mechanism 86 at the bottom;

[0032] By introducing the raw material into the fixed mold 3 and starting the cylinder 4 to drive the slide plate 7 to move vertically, the slide plate 7 drives the movable mold 10 to move vertically and connect with the fixed mold 3, so that the fixed mold 3 cooperates with the movable mold 10 to extrude the raw material to form a product.

[0033] like Figure 2 As shown, in this embodiment, the positioning mechanism 8 and the auxiliary mechanism 9 are arranged at the bottom of the slide plate 7. The positioning mechanism 8 includes a buffer spring 81, a first ring 82, a second ring 83, a scale line 84, an adjustment mechanism 85 and a mounting mechanism 86. The two ends of the buffer spring 81 are respectively connected to the bottom end surface of the first ring 82 and the top end surface of the second ring 83, and the inner end surface of the buffer spring 81 is movably connected to the side surface of the hollow column 6 for buffering the slide plate 7. The first ring 82 and the second ring 83 are movably sleeved on the side surface of the hollow column 6. The second ring 83 moves vertically on the outside of the hollow column 6 through the adjustment mechanism 85 for auxiliary support of the slide plate 7 to prevent the slide plate 7 from driving the sliding mold 10 to form an excessive impact force on the fixed mold 3.

The transmission plate 856 is slidably mounted on the inner side of the hollow column 6, and the connecting plate 857 is mounted on the side surface of the transmission plate 856. The connecting plate 857 passes through the inner side end surface of the hollow column 6 and is fixedly connected with the inner ring of the second ring 83, so as to drive the second ring 83 to move vertically, thereby realizing that the second ring 83 drives the buffer spring 81 and the first ring 81 to move vertically;

[0037] In this embodiment, four connecting plates 857 are evenly spaced on the outer end surface of the transmission plate 856, and four strip holes corresponding to the connecting plates 857 are opened on the inner side of the hollow column 6, so that the transmission plate 856 can drive the second ring 83 to move vertically stably through the multiple connecting plates 857;

[0044] The barb 93 is moved outward by pressure during vertical movement, and the barb 93 drives the spring 924 to stretch. When the barb 93 is aligned with the limit frame 96, the barb 93 is moved inward into the limit frame 96 by the elastic force of the spring 924, so that the top surface of the barb 93 contacts the top inner side of the limit frame 96, so that the barb 93 cooperates with the connecting plate 91 and the sliding plate 921 to assist in positioning the slide plate 7 and the movable mold 10, thereby preventing the slide 7 and the movable mold 10 from shaking during use and affecting the product quality.
