[0042] A plurality of universal pipe seats 1 are installed on one side of the positioning cover 41, and the universal pipe seat 1 includes a spherical rotating block 47, a semicircular positioning card cover 48 and a hose section 45. The hose section 45 is fixedly installed in the inner cavity of the pipe slot 44 in a through-shaped manner, and the end of the hose section 45 is fixedly connected with a hard pipe section 46 in a connected manner. The semicircular positioning card cover 48 is fixedly installed on one side of the injection mold structure 1, and the spherical rotating block 47 is rotatably connected to the inner cavity of the semicircular positioning card cover 48. A through-pipe groove is opened inside the spherical rotating block 47 and the semicircular positioning card cover 48.

A spring member 2 410 is installed between the positioning seat 49 and the hard pipe section 46, and the spring member 2 410 includes a tension spring member or a spring member.

[0043] like Fig. 9As shown, a universal pipe seat 2 is installed on the top of the hard pipe section 46, and a fan-shaped liquid outlet disc 411 is hinged on the top of the hard pipe section 46 through the universal pipe seat 2. The hard pipe section 46 is connected to the fan-shaped liquid outlet disc 411 through the universal pipe seat 2. The fan-shaped liquid outlet disc 411 is hollow, and a side of the fan-shaped liquid outlet disc 411 away from the positioning cover 41 is provided with multiple injection liquid discharge outlets; the structure of the universal pipe seat 1 is consistent with that of the universal pipe seat 2; the number of the fan-shaped liquid outlet discs 411 is set to be multiple, and the multiple fan-shaped liquid outlet discs 411 are connected by a fan-shaped rubber connecting piece 412, and a central rubber end head 413 is fixedly installed in the middle of the fan-shaped liquid outlet disc 411 and the fan-shaped rubber connecting piece 412, and the fan-shaped rubber connecting piece 412 and the central rubber end head 413 are used to generate deformation when the fan-shaped liquid outlet disc 411 slides.

[0044] It should be noted that if Figure 3 As shown, the inlet from flow channel 1 to flow channel 2 is at the position of the first injection tube segment 1 22 close to the injection mold structure 1, and the inlet from flow channel 2 to flow channel 3 is at the position of the first injection tube segment 1 22 close to the semicircular injection tube 21, and finally the injection liquid in flow channel 3 flows to the hard tube segment 46 through the hose segment 45 of the universal pipe seat 1, and the injection liquid in the hard tube segment 46 flows to the inner cavity of the fan-shaped liquid outlet plate 411 through the hose segment 45 of the universal pipe seat 2, and finally is discharged from the injection liquid outlet opened on the surface of the fan-shaped liquid outlet plate 411 to the inner cavity of the injection mold structure 1;

[0045] It should also be noted that the fan-shaped liquid outlet plate 411, the fan-shaped rubber connecting piece 412 and the central rubber end 413 are used to make the plane as close to the injection liquid as possible, so that the generation of bubbles can be reduced when the injection liquid flows. In addition, the larger the injection liquid outlet on the surface of the fan-shaped liquid outlet plate 411, the smaller the probability of bubble generation, and the smaller the injection liquid outlet, the greater the probability of bubble generation. It can be selected according to actual use needs.

[0046] As for the use of this solution, it is necessary to further explain the overall situation: in actual use, the main injection tube 31 is first connected to the injection pipe or the liquid outlet of the injection molding machine, and the injection liquid flows through the main injection tube 31 to the inner cavity of the branch injection tube 32, such as Figure 2 As shown, the semicircular structure of the semicircular injection tube 21 is to allow the sliding push rod 24 to slide along with the second injection tube. At this time, the liquid outlet structure 4 is pre-installed in the inner cavity of the mold 1 101 and the mold 2 102. If the injection mold structure 1 or the injection pipe structure 2 is displaced during injection molding, the injection mold structure 1 or the injection pipe structure 2 can be fixed by bolts through a workbench or a disc seat;

[0047] When the injection liquid in the inner cavity of the branch injection tube 32 flows to the flow channel 1 through the semicircular injection tube 21, as shown in FIG. Figure 3As shown, the inlet from flow channel 1 to flow channel 2 is located at the position of the first injection molding pipe section 1 22 close to the injection mold structure 1, and the inlet from flow channel 2 to flow channel 3 is located at the position of the first injection molding pipe section 1 22 close to the semicircular injection molding pipe 21, and finally the injection molding liquid in flow channel 3 flows to the hard pipe section 46 through the hose section 45 of the universal pipe seat 1, and the injection molding liquid in the hard pipe section 46 flows to the inner cavity of the fan-shaped liquid outlet plate 411 through the hose section 45 of the universal pipe seat 2, and finally is discharged from the injection molding liquid outlet opened on the surface of the fan-shaped liquid outlet plate 411 to the inner cavity of the injection mold structure 1; the fan-shaped liquid outlet plate 411, the fan-shaped rubber connecting piece 412 and the middle rubber end 413 are used to make the plane as close to the injection molding liquid as possible, so that the generation of bubbles can be reduced when the injection molding liquid flows, and in addition, the larger the injection molding liquid outlet on the surface of the fan-shaped liquid outlet plate 411, the smaller the probability of bubble generation, and the smaller the injection molding liquid outlet, the greater the probability of bubble generation, which can be selected according to actual use needs;

[0048] In addition, during the process of discharging liquid from the fan-shaped liquid outlet plate 411, since the push rod piston 210 slides in the inner cavity of the first injection molding tube section 25 in a piston-like manner, after the inner cavity of the first injection molding tube section 25 is filled with injection molding liquid, the injection molding liquid is continuously added under pressure, so that the injection molding liquid is added to the inner cavity of the injection mold structure 1, and the injection molding liquid pushes the second injection molding tube and the push rod piston 210 to move toward the position of the multi-station injection molding tube structure 3. In this way, when the holding operating arm 211 is seen approaching the multi-station injection molding tube structure 3, it can be known whether the injection molding of the injection mold structure 1 of the multi-station injection molding is completed. Of course, this scheme also has an auxiliary scheme. In order to reduce the failure rate of actual use, if the sliding push rod 24 and the push rod piston 210 cannot be pushed due to the pressure of the injection molding liquid, a spring member 214 can be installed between the hook segment 1 212 and the hook segment 2 213. At this time, the spring member 214 can be selected as a tension spring, otherwise a spring can be selected;

[0049] Wherein, the universal pipe seat 1 and the universal pipe seat 2 allow the two ends of the hard pipe section 46 to form a hinged state under the premise of ensuring that the injection liquid can flow into the inner cavity of the injection mold structure 1, and the tension spring or spring of the spring member 2 410 is used to allow the hard pipe section 46 to push the fan-shaped liquid outlet plate 411 to fit into the inner cavity of the injection mold structure 1 as much as possible, so as to further reduce the generation of bubbles. The arrangement of the fan-shaped rubber connecting piece 412 and the central rubber end head 413 can deform the fan-shaped liquid outlet plate 411 when it is close to the inner cavity of the injection mold structure 1 to form a surface that is as complete as possible to fit the injection liquid surface. This solution is more suitable for injection molding of non-standard cylindrical precision models with different diameters; in addition, the holding operating arm 211 can also manually intervene in the position of the liquid outlet structure 4.
