[0002] For injection molded parts with special structures, such as Figure 1 The airbag frame shown has a hanging cloth 200. Figure 2 Before molding, the hanging cloth 200 needs to be fixed to the mold. After injection molding, the hanging cloth 200 and the product 100 are combined into one.

[0003] The two sides of the hanging cloth 200 are bent to form a vertical side surface 201. It is necessary to open a corresponding slot on the mold to squeeze the vertical side surface 201, so as to fix the hanging cloth 200 on the mold. Usually, the width of the slot is slightly smaller than the thickness of the vertical side surface 201, so that the two form an interference fit, so that the hanging cloth 200 will not move after being fixed.

[0037] Preferably, the first driving cylinder 16 and the second driving cylinder 23 are both hydraulic cylinders with high control accuracy.

[0038] The first core pull 11 and the second core pull 21 both move, and form a space on the side corresponding to the support block 14, which is convenient for placing the hanging cloth 200. After that, the first core pull 11 and the second core pull 21 move again, and squeeze the vertical side surface 201 of the hanging cloth 200 on the corresponding side with the support block 14, and complete the placement and fixation of the hanging cloth 200 on the mold. The placement action is convenient, the placement success rate is high, and it is suitable for robot operation, which improves the placement efficiency of the hanging cloth 200.

[0039] When the mold is opened, the first core puller 11 and the second core puller 21 are first kept in a clamped state; when the frame opening inclined ejector block 1 and the tie rod inclined ejector block 2 are ejected, they move to separate from the supporting block 14 to form a space.

[0040] As an embodiment, a slide rail 15 is fixed on the frame opening inclined ejector block 1, and a rail seat 111 that slides with the slide rail 15 is fixed on the first core pull 11; the second core pull 21 is fixed to a guide column 24, and the guide column 24 slides through the tie rod inclined ejector block 2;

[0041] As an example, see Figure 5 Two first limit switches 17 for limiting the stroke of the first core pulling 11 are provided on the frame opening inclined top block 1; a sensing block 112 is fixed on the first core pulling 11; the distance between the two first limit switches 17 limits the stroke of the first core pulling 11; during the movement of the first core pulling 11, when the sensing block 112 is sensed by the first limit switch 17 on one side, a stop signal is issued.

[0042] See also Figure 7 Furthermore, two second limit switches 25 for the stroke of the second core pulling 21 are provided on the tie rod inclined top block 2; a sensing plate 26 is fixed on the second core pulling 21, and a sensing claw 261 is fixed on the sensing plate 26; the sensing plate 26 and the sensing claw 261 respectively have sensing surfaces; the distance between the two sensing surfaces is the same as the distance between the two second limit switches 25, and they respectively cooperate with the second limit switches 25 on the corresponding side.

[0043] Optionally, the first limit switch 17 and the second limit switch 25 of the present invention are proximity switches or contact switches.

[0044] See also Figure 8 The present invention also provides an injection mold, comprising a movable mold 5 and a fixed mold; the movable mold 5 is equipped with the airbag frame hanging cloth pre-clamping mechanism;

[0045] Combination Figure 1 and Figure 2 The injection mold of the present invention is used to mold a product 100, wherein the product 100 has a frame structure 101, a rib structure 102 adjacent to the frame structure 101, and a hanging cloth 200 inside the frame structure 101. The frame structure 101 and the rib structure 102 are both in an inverted form, and the demoulding directions of the two are different, so it is impossible to use a tilting block for molding.

[0046] The frame opening inclined top block 1 of the present invention is used to form a frame opening structure 101, and the tie rod inclined top block 2 is used to form a tie rod structure 102;

[0047] The frame opening inclined ejector block 1 of the airbag frame hanging cloth pre-clamping mechanism is connected to the frame opening inclined ejector rod 12, and the tie rod inclined ejector block 2 is connected to the tie rod inclined ejector rod 22; the frame opening inclined ejector rod 12 and the tie rod inclined ejector block 2 are both slidably arranged in the slide seat 3;

[0048] A movable platen 51 is provided on one side of the movable mold 5, and a needle plate 52 is provided on the movable mold 5 and the movable platen 51; the slide seat 3 is arranged in the needle plate 52;

[0052] Due to the distance limit between the frame opening structure 101 and the tie rod structure 102 of the product 100, the frame opening inclined ejector block 1 and the tie rod inclined ejector block 2 are arranged close to each other, so that there is not enough space on the needle plate 52 to install the frame opening inclined ejector rod 12 and the tie rod inclined ejector rod 22. The present invention slides two sets of inclined ejector rods with different ejection directions on the same slide seat 3, thereby realizing the installation of two sets of inclined ejector rods in a compact structure.

[0053] As an embodiment, a baffle 33 is further provided at the end position of the slide groove cavity of the slide seat 3 to prevent the slider 34 from being disengaged.

[0056] In summary, the present invention provides an airbag frame hanging cloth pre-clamping mechanism, which forms a space with one side corresponding to the supporting block through the first core pulling action and the second core pulling action, so as to facilitate the placement of the hanging cloth. Afterwards, the first core pulling and the second core pulling respectively squeeze the vertical side surface of the hanging cloth on the corresponding side with the supporting block, so as to complete the placement and fixation of the hanging cloth on the mold. The placement action is convenient, the placement success rate is high, and it is suitable for robot operation, which improves the placement efficiency of the hanging cloth. The present invention also provides an injection mold with an airbag frame hanging cloth pre-clamping mechanism.
