Description

Technical Field

[0001] The utility model relates to the technical field of injection molding, in particular to a glue guide component for injection molding. Background Art

[0002] In the production process of automobile connectors, they need to be injection molded. When the injection mold is injecting, the glue needs to enter the mold through the sprue sleeve. After the glue enters the sprue sleeve, it finally flows into the mold to complete the injection molding.

[0003] In the related art, the existing injection mold guide assembly is installed on a mold frame with a mold core. When injection molding, the glue enters from the gate sleeve, then flows into the main channel, and then enters the nozzle through the runner groove, and flows out through the nozzle into the cavity formed by the mold core. This technology is equipped with three nozzles, which is suitable for large-scale annular or disc-shaped automotive connector injection molding parts.

[0004] In practical applications, the glue enters the gate sleeve and flows into the main channel, and then enters the three nozzles through the runner groove. The three nozzles are conducive to the injection molding of large annular or disc-shaped injection molded parts. However, since the nozzle is fixed on the mold and cannot be adjusted, it cannot be adjusted in size according to the size of the mold, resulting in poor injection efficiency and low practicality.

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0023] Example

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, the utility model provides a technical solution: comprising a delivery pipe 1, a sprue sleeve 3 is installed on the top of the delivery pipe 1, and the glue is poured into the inside of the delivery pipe 1 through the sprue sleeve 3, three connecting pipes 2 are arranged on the outside of the delivery pipe 1, and the outside of the connecting pipes 2 are slidably connected with telescopic pipes 6, and an adjustment mechanism 5 is arranged between the connecting pipes 2 and the telescopic pipes 6;

[0025] The adjusting mechanism 5 comprises a slide bar 501, and a mounting seat 502 is fixedly connected to one side of the top of the telescopic tube 6, and the internal components thereof are protected by the mounting seat 502. The inside of the mounting seat 502 is slidably connected to the slide bar 501, and the bottom end of the slide bar 501 passes through the mounting seat 502 and is fixedly connected to a positioning block 505, and a disc 504 is fixedly connected to the outside of the slide bar 501 and located inside the mounting seat 502, and a spring 503 is sleeved on the outside of the slide bar 501 between the top of the disc 504 and the inside of the mounting seat 502, and a slide groove 507 is provided on the top of the connecting tube 2, and limiting grooves 506 are evenly spaced inside the slide groove 507, and the positioning block 505 is slidably connected to the limiting groove 506.

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, the disc 504 is slidably connected to the mounting seat 502, and the top and bottom of the spring 503 are fixedly connected to the mounting seat 502 and the disc 504 respectively.

[0027] In this embodiment, by pulling the slide bar 501 upward, the bottom of the slide bar 501 drives the positioning block 505 to disengage from the interior of the limiting groove 506, and at the same time, the disc 504 slides upward inside the mounting seat 502, so that the spring 503 is squeezed by the force, and then the telescopic tube 6 is slid outward along the outer side of the connecting tube 2. After loosening the slide bar 501, the spring 503 is relieved of the force, and then the positioning block 505 enters the interior of the limiting groove 506 to fix the adjusted telescopic tube 6 to the connecting tube 2. By adjusting the length of the telescopic tube 6, it is beneficial to inject molded parts of different sizes, thereby improving the efficiency and practicality of injection molding.

[0028] Furthermore, the outer side of the bottom of the telescopic tube 6 is threadedly connected with a threaded sleeve 8, and the bottom of the threaded sleeve 8 is fixedly connected with a nozzle 7. By rotating the threaded sleeve 8, the nozzle 7 can be quickly replaced and repaired to prevent affecting the use of the guide component.

[0029] Furthermore, the top of the slide bar 501 passes through the mounting seat 502 and is fixedly connected with a knob 9 , and the outer side of the knob 9 is provided with anti-slip textures. The provision of the knob 9 is conducive to the rapid movement of the slide bar 501 to control the positioning block 505 .

[0030] Furthermore, the telescopic tube 6 is of L-shaped design, and the inclination angle between the connecting tube 2 and the conveying tube 1 is 10°. A certain inclination angle is set between the connecting tube 2 and the conveying tube 1, which is beneficial for the glue at the conveying tube 1 to quickly flow into the connecting tube 2 and quickly flow into the interior of the telescopic tube 6.

[0031] Furthermore, electric heating wires 4 are installed on the outside of the telescopic tubes 6, and the electric heating wires 4 are electrically connected to the external controller. By starting the electric heating wires 4, the glue inside the telescopic tubes 6 can be heated to prevent the glue flowing in from the connecting tube 2 from solidifying and affecting use. At the same time, the electric heating wires 4 can be quickly controlled by the external controller.

[0032] Working principle:

[0033] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, when in use, the glue is poured into the interior of the delivery tube 1 through the sprue sleeve 3, and then the glue is transported to the interior of the telescopic tube 2 through the delivery tube 1, and then transported to the interior of the nozzle 7 through the connecting tube 6, and injection molding is performed through the nozzle 7;

[0034] When adjustment is needed, the slide bar 501 is pulled upward so that the bottom of the slide bar 501 drives the positioning block 505 to disengage from the inside of the limiting groove 506. At the same time, the disc 504 slides upward inside the mounting seat 502, so that the spring 503 is squeezed by the force, and then the telescopic tube 6 is slid outward along the outside of the connecting tube 2. After the slide bar 501 is loosened, the spring 503 is relieved of the force, and then the positioning block 505 enters the inside of the limiting groove 506 to fix the adjusted telescopic tube 6 to the connecting tube 2. By adjusting the length of the telescopic tube 6, it is beneficial to injection molding of injection molded parts of different sizes, thereby improving the efficiency and practicality of injection molding.
