Description

Technical Field

[0001] This utility model belongs to the field of automotive duct processing technology, and in particular relates to an automotive duct injection molding device. Background Technology

[0002] When automotive duct components are injection molded, an injection molding machine is required. It uses the thrust of a screw (or plunger) to inject pre-plasticized molten plastic (i.e., viscous flow state) into a closed mold cavity. After solidification and shaping, the product is obtained. Injection molding is a cyclical process. Each cycle mainly includes: quantitative feeding - melting and plasticizing - pressure injection - mold filling and cooling - mold opening and part removal. After the plastic part is removed, the mold is closed again to start the next cycle.

[0003] Injection molding machines are equipped with a feed hopper on top, and most of them are fixed installations. In actual use, feed blockage may occur. Therefore, an automotive air duct injection molding device is needed, which can reciprocate the raw material in the feed hopper in the vertical direction, so as to avoid blockage of the raw material in the feed hopper during the feeding process, thereby ensuring the smooth feeding of the molding machine. Utility Model Content

[0004] The purpose of this invention is to provide an injection molding device for automotive air ducts, which reciprocates the raw material in the feed hopper in the vertical direction to prevent blockage during the feeding process, thereby ensuring the smooth feeding of the molding machine and solving the technical problems mentioned in the background art.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: An injection molding device for automotive air ducts includes a body: the top of the body is connected to a through pipe, a feed hopper is slidably connected to the surface of the through pipe, a vertical plate is fixedly installed on the top of the body, an electric telescopic rod and a slide rail are fixedly installed on the surface of the vertical plate by bolts, a slider is slidably connected to the surface of the slide rail, a slide plate is fixedly connected to the output end of the electric telescopic rod by a flange, a dial shaft is fixedly connected to the surface of the slider, and a vertical pipe is fixedly connected to the surface of the slider.

[0006] Preferably, a slip ring is fixedly installed on the surface of the feed hopper, and a vertical rod is welded to the top of the machine body, with the slip ring and the vertical rod being slidably connected.

[0007] Preferably, the end of the dial shaft extends into the inner cavity of the slide plate, a rotating sleeve is rotatably connected to the surface of the dial shaft, and the through tube is in contact with the inner wall of the slide plate.

[0008] Preferably, a clamping block is fixedly installed on the surface of the upright plate by bolts, and the clamping block is slidably connected to the surface of the sliding plate.

[0009] Preferably, a T-shaped rod is slidably connected to the inner wall of the riser, the T-shaped rod is fixedly connected to the feed hopper, and a spring is fixedly connected to both the T-shaped rod and the riser.

[0010] Preferably, the top of the tube is integrally formed with a guide ring.

[0011] The beneficial effects of this utility model are:

[0012] 1. This utility model uses a slider to drive the vertical tube to move back and forth in the vertical direction, which in turn drives the feed hopper to move up and down on the surface of the tube. This achieves the goal of reciprocating vibration of the raw material in the feed hopper in the vertical direction, thereby preventing blockage of the raw material in the feed hopper during the feeding process and ensuring the smooth feeding of the molding machine.

[0013] 2. This utility model uses the cooperation of slip ring and upright to limit the feeding hopper, thus preventing the feeding hopper from shaking during vertical movement;

[0014] 3. By setting up the rotating sleeve, this utility model protects the surface of the dial shaft by padding it, thus preventing the latter's surface from wearing out too quickly when the slide plate comes into direct contact with the dial shaft.

[0015] 4. This utility model uses the combination of T-shaped rod and spring to make the feed hopper and the vertical pipe elastically connected, which further increases the frequency of vertical vibration of the feed hopper, thereby further improving the smoothness of the material falling in the feed hopper.

[0016] 5. This utility model uses a guide ring to guide the top of the pipe at a slope, thus preventing raw materials from accumulating at the top of the pipe. Attached Figure Description

[0024] In the following description, embodiments of the automotive duct injection molding apparatus of the present invention will be described with reference to the accompanying drawings.

[0025] Example 1:

[0026] Figure 1-4 This invention illustrates an embodiment of an automotive duct injection molding apparatus, comprising a body 1. A through pipe 2 is connected to the top of the body 1, and a feed hopper 3 is slidably connected to the surface of the through pipe 2. A slip ring 4 is fixedly installed on the surface of the feed hopper 3. A vertical rod 5 is welded to the top of the body 1, and the slip ring 4 and the vertical rod 5 are slidably connected. The slip ring 4 and the vertical rod 5 work together to limit the movement of the feed hopper 3, preventing it from wobbling during vertical movement. A vertical plate 6 is fixedly installed on the top of the body 1, and an electric motor is bolted to the surface of the vertical plate 6. Telescopic rod 7 and slide rail 8, slide rail 8 has a slider 9 slidably connected to its surface, slide plate 10 is fixedly connected to the output end of electric telescopic rod 7 via flange, slider 9 has a pivot shaft 11 fixedly connected to its surface, the end of pivot shaft 11 extends into the inner cavity of slide plate 10, pivot shaft 11 has a rotating sleeve 12 rotatably connected to its surface, through pipe 2 fits against the inner wall of slide plate 10, pivot sleeve 12 is provided to protect the surface of pivot shaft 11, avoiding the situation where the surface of pivot shaft 11 wears too quickly when slide plate 10 directly contacts pivot shaft 11, and vertical pipe 14 is fixedly connected to the surface of slider 9.

[0027] Example 2:

[0028] Figure 1-4This invention illustrates an embodiment of an automotive duct injection molding apparatus, comprising a body 1. A through-pipe 2 is connected to the top of the body 1, and a feed hopper 3 is slidably connected to the surface of the through-pipe 2. A vertical plate 6 is fixedly mounted on the top of the body 1. An electric telescopic rod 7 and a slide rail 8 are bolted to the surface of the vertical plate 6. A slider 9 is slidably connected to the surface of the slide rail 8. A slide plate 10 is fixedly connected to the output end of the electric telescopic rod 7 via a flange. A pivot shaft 11 is fixedly connected to the surface of the slider 9. A clamping block 13 is bolted to the surface of the vertical plate 6, and the clamping block 13 is slidably connected to the surface of the slide plate 10. A [missing information - likely a specific component or component] is fixedly connected to the surface of the slider 9. The riser 14 has a T-shaped rod 15 slidably connected to its inner wall. The T-shaped rod 15 is fixedly connected to the feed hopper 3. A spring 16 is fixedly connected to both the T-shaped rod 15 and the riser 14. Through the cooperation of the T-shaped rod 15 and the spring 16, the feed hopper 3 and the riser 14 can be elastically connected, which further increases the frequency of vertical vibration of the feed hopper 3, thereby further improving the smoothness of the material falling in the feed hopper 3. The top of the passage pipe 2 is integrally formed with a guide ring 17. The guide ring 17 is set to guide the top of the passage pipe 2 with a slope, avoiding the accumulation of material at the top of the passage pipe 2.

[0029] Working principle: When using this utility model, the user pours the raw material into the feeding hopper 3. At this time, the electric telescopic rod 7 is activated to drive the slide plate 10 to move. The slide plate 10 drives the slider 9 to slide on the surface of the slide rail 8 through the pivot shaft 11. During this process, the movement of the slide plate 10 is limited by the clamping block 13 to prevent the slide plate 10 from shaking during movement. This causes the slider 9 to drive the vertical pipe 14 to move back and forth in the vertical direction. The vertical pipe 14 drives the feeding hopper 3 to move up and down on the surface of the through pipe 2. Then, the raw material in the feeding hopper 3 enters the machine body 1 smoothly through the through pipe 2. This realizes the reciprocating vibration of the raw material in the feeding hopper in the vertical direction, thereby preventing the raw material in the feeding hopper from getting blocked during the feeding process, and thus ensuring the smooth feeding of the molding machine.

[0030] In summary, this automotive duct injection molding device uses a slider 9 to drive the vertical pipe 14 to move back and forth in the vertical direction. This causes the vertical pipe 14 to move the feed hopper 3 up and down on the surface of the through pipe 2, thereby achieving reciprocating vibration of the raw material in the feed hopper in the vertical direction. This prevents blockage of the raw material in the feed hopper during the feeding process, thus ensuring the smooth feeding of the molding machine.
