Description

Technical Field

[0001] The utility model belongs to the technical field of injection molding of automobile accessories and relates to an injection mold for an automobile air-conditioning outlet panel. Background Art

[0002] Side core-pulling injection molds are a common type of injection molds. The characteristic of this type of mold is that the side of the molded plastic part has a measuring hole or side concave that is inconsistent with the mold opening direction. Therefore, in order to allow the plastic part with a hole or groove on the side to be smoothly ejected from the cavity, side core pulling is required before or during demolding.

[0003] The side core pulling mechanism of the injection mold is generally a relatively simple side pulling component that cooperates with an oblique pin and a horizontal slider. The oblique pin is fixed on the upper mold, and the horizontal slider is installed on the lower mold, and the oblique pin is fitted into the oblique hole of the horizontal slider. When the mold is opened, the upper mold moves up, and the oblique pin pushes the horizontal slider to slide along the slideway of the lower mold. The advantage of this side core pulling mechanism is that there is no need to add a new power source. The mold opening action of the injection molding machine is used to pull the horizontal slider through the oblique pin, and the side core pulling action is synchronously realized during demolding. However, the above-mentioned side core pulling injection mold has obvious defects: the side core pulling distance cannot be adjusted, and the side core pulling is completely synchronized with the mold opening process, and the interval time between the two actions cannot be adjusted. Therefore, it is inconvenient in practical application, has poor versatility, and is difficult to meet the diversified needs of mold injection. Utility Model Content

A block is fixed to the notch of the slide groove, and the outer end of the return spring abuts against the block, and the inner end of the return spring abuts against the inner wall of the spring groove. A guide seat is fixed to the outer wall of the lower template, and a guide wheel is rotatably connected between the two guide seats. A winding seat is fixed on the support plate, and a winding roller is rotatably connected between the two winding seats. One end of the rotating shaft of the winding roller passes through the winding seat and is connected to a synchronously rotating gear. A locking claw is rotatably connected to the side of the winding seat, and a locking spring is also provided on the winding seat for pushing the locking claw toward the gear and preventing the gear from rotating. A traction rope is tied to the outer side of the transverse slider, and the traction rope is connected to the winding roller after passing around the guide wheel.

[0006] Furthermore, the slide groove has protruding limit sliding blocks on both sides, and the transverse sliding block has limit straight grooves on both sides. The limit sliding blocks are embedded in the limit straight grooves and can slide relative to the limit straight grooves.

[0007] Furthermore, a guide column is fixed on the lower base plate, the guide column is against the lower template, and a guide sliding hole that is slidably matched with the guide column is opened on the ejection plate.

The molten plastic liquid enters the injection needle tube from the injection joint, and finally enters the injection pipe and is transported to the mold cavity. After the product is cooled and finalized, the mold is opened, and the support plate and the upper template move up together. During the upward movement, the winding roller continuously tightens the traction rope until the traction rope pulls the transverse slider to slide outward, so that the round rod is separated from the connecting pipe head and the side core pulling operation is completed. At this time, the unloading cylinder can be started to drive the ejector plate to move up, and the ejector plate drives the ejector rod to move up. The ejector rod pushes the ejector plate to move up, so that the product is separated from the mold cavity of the lower template and the product can be taken out. If you need to adjust the start time and sliding distance of the side core pulling, manually lift the locking claw, the locking spring is compressed, and then turn the handle to rotate the winding roller to reel in or release the traction rope, and then release the locking claw, so that the locking spring pushes the locking claw to swing and firmly clamp the gear, so that the winding roller will not rotate.

[0015] Compared with the prior art, the injection mold of the automobile air-conditioning outlet panel has the following advantages:

[0016] 1. By turning the gear, a longer traction rope is released from the winding roller, which can delay the time of pulling the horizontal slider outward, thereby adjusting the interval time between mold opening and side core pulling.

[0017] 2. The height of the winding seat can be adjusted, and at the same time, the length of the traction rope released by the winding roller can be adjusted. The side core pulling distance can be adjusted without adjusting the mold opening height of the upper template. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] like Figure 2As shown, the lower template 4 has slide grooves on both sides, and a transverse slider 11 is slidably arranged in the slide groove. The inner side of the transverse slider 11 has a transversely protruding round rod 12 that can be inserted into the connecting pipe head 71. The lower template 4 has a round hole 29, and the round rod 12 passes through the connecting pipe head 71 and is inserted into the round hole 29. A spring groove is opened at the bottom of the transverse slider 11, and a return spring 13 is built in the spring groove. A stopper 14 is fixed to the notch of the slide groove, and the outer end of the return spring 13 abuts against the stopper 14, and the inner end of the return spring 13 abuts against the inner wall of the spring groove. A guide seat 15 is fixed to the outer wall of the lower template 4, and a guide wheel 16 is rotatably connected between the two guide seats 15.

[0027] The two sides of the slide groove are provided with protruding limit sliders 23, and the two sides of the transverse slider 11 are provided with limit straight grooves, and the limit sliders 23 are embedded in the limit straight grooves and can slide relative to the limit straight grooves.

[0028] like Figure 3 As shown, a winding seat 17 is fixed on the support plate 2, and a winding roller 18 is rotatably connected between the two winding seats 17. One end of the rotating shaft of the winding roller 18 passes through the winding seat 17 and is connected to a synchronously rotating gear 19. A locking claw 20 is rotatably connected to the side of the winding seat 17. The winding seat 17 is also provided with a locking spring 21 for pushing the locking claw 20 toward the gear 19 and preventing the gear 19 from rotating.
