DETAILED DESCRIPTION

[0028] The specific implementation modes of the present invention are further described below in conjunction with the accompanying drawings to make the technical solutions of the present invention easier to understand and grasp.

[0029] A kind of oblique ejection injection mold for automobile air outlet decorative strips, comprising a top plate 1, an upper mold 2, a lower mold 3, an ejection plate 4 and a bottom plate 5 arranged in sequence, a plurality of oblique draw grooves 6 are opened on the top surface of the lower mold 3, an oblique draw block 7 is embedded in the oblique draw groove 6, an oblique ejection hole 8 is opened at the bottom of the oblique draw groove 6, an oblique ejector rod 9 fixedly connected to the oblique draw block 7 is arranged in the oblique ejector hole 8, the other end of the oblique ejector rod 9 is fixed to the ejection plate 4, an oblique ejector assembly 10 is arranged on the ejection plate 4, and the oblique ejector assembly 10 is used to drive the oblique ejector rod 9 to eject obliquely.

[0030] A plurality of straight ejector blocks 11 are also embedded in the lower mold 3, and a straight ejector rod 12 is provided at the tail of the straight ejector block 11. The straight ejector rod 12 is fixedly connected to the ejection plate 4. A cavity for molding the decorative strip body 90 is formed between the oblique pull-out block 7, the straight ejector block 11, the upper mold 2 and the lower mold 3. When the ejection plate 4 drives the straight ejector block 11 and the oblique pull-out block 7 to move upward together, the oblique pull-out block 7 is disengaged from the undercut 92. A plurality of anti-movement grooves 13 are provided on the straight ejector block 11. When the straight ejector block 11 is ejected, the anti-movement grooves 13 limit the position of the decorative strip body 90 to prevent the oblique pull-out block 7 from driving the product to tilt and move during the oblique ejection process.

[0031] The inclined ejector assembly 10 includes a recessed block 14, a pair of sliders 15 and a hinge block 16. A pair of inclined grooves 17 for the sliders 15 to slide are symmetrically provided on the inner side of the recessed block 14. The two sides of the hinge block 16 are hinged to the two sliders 15 respectively. The tail of the inclined ejector rod 9 is fixedly set on the hinge block 16. A sinking groove 18 for fixing the clamping block is provided on the top surface of the ejection plate 4. The ejection plate 4 also has a through groove 19 running through it. When interference occurs between the recessed blocks 14 because the undercuts 92 are too close, the two recessed blocks 14 are fixedly installed in the sinking groove 18 and the through groove 19 respectively, so that they are staggered up and down to avoid interference.

[0032] A side draw groove 20 is also provided on the lower mold 3, and pressure plates 21 are provided at both ends of the side draw groove 20. The pressure plate 21 and the side draw groove 20 form a T-shaped groove. A side draw block 22 is slidably provided in the side draw groove 20, and a side draw die head 23 is provided on the end face of the side draw block 22. An oblique draw hole 24 is provided at the upper end of the side draw block 22, and an oblique draw rod 25 is fixedly provided at the bottom of the upper mold 2. When the mold is opened, the oblique draw rod 25 drives the side draw block 22 to move along the direction of the side draw groove 20, thereby separating the side draw die head 23 from the decorative panel body to complete the side end core pulling.

[0033] A spring hole 26 is provided on the side withdrawal block 22, and an anti-movement spring 27 is arranged in the spring hole 26. One end of the anti-movement spring 27 abuts against the lower mold 3, and the other end abuts against the bottom surface of the spring hole 26. A limiting block 29 is also fixedly provided on the lower mold 3, and a limiting slide groove 28 is provided at the bottom of the side withdrawal block 22. When the oblique withdrawal rod 25 is separated from the oblique withdrawal hole 24 during mold opening, the limiting block 29 abuts against one end of the limiting slide groove 28. At the same time, the anti-movement spring 27 abuts against the side withdrawal block 22 and makes the limiting block 29 abut against the limiting slide groove 28. When the mold vibrates, the anti-movement spring 27 keeps the position of the side withdrawal block 22 unchanged, thereby avoiding the movement of the side withdrawal block 22 due to vibration and other problems when the mold is opened, which further causes the problem that the oblique withdrawal rod 25 cannot enter the oblique withdrawal hole 24 when the mold is closed.

[0034] Of course, the above are only typical examples of the present invention. In addition, the present invention may have many other specific implementations. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present invention.
