Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, specifically to a glue injection mechanism for a multi-point glue injection mold. Background Technology

[0002] Multi-point injection molding is a technique in which plastic raw materials enter the mold cavity through multiple injection points during the injection molding process. This technique allows for more uniform injection of plastic raw materials, thereby improving product quality. Currently, multi-point injection molds require a matching injection mechanism. The plastic material is fed into a distributor via a feeding assembly, which then distributes the plastic material evenly into multiple injection nozzles. These nozzles then deliver the plastic material to the injection points of the multi-point injection mold, completing the multi-point injection process.

[0003] However, existing technologies do not allow for flexible adjustment of the injection angles of multiple injection nozzles on the distributor, thus failing to better meet the different injection point requirements of different multi-point injection molds. Furthermore, they do not allow for flexible adjustment of the injection speed, making it difficult to flexibly control the injection speed of multiple injection nozzles.

[0004] Therefore, a glue injection mechanism for multi-point glue injection molds is proposed. Utility Model Content

[0011] Furthermore, the output shaft of the drive motor passes through one side of the fixed cover, and the driving bevel gear and the driven bevel gear mesh with each other and are both located inside the fixed cover.

[0012] Furthermore, the bottom of the feeder cylinder and the top of the support base are welded with the same H-shaped bracket, and the speed drive includes a frequency converter fixedly installed on the side wall of the support base, a support plate welded to the side wall of the H-shaped bracket, a speed motor fixedly installed on the top outer wall of the support plate, a speed gear fixedly mounted on the output shaft of the speed motor, and a transmission gear fixedly mounted on the glue feeding screw.

[0013] Furthermore, the top end of the glue feeding tube penetrates the top of the fixed cover, and a rotary joint is provided between the glue feeding tube and the discharge tube. The top end of the glue feeding tube is sealed and fixedly connected to the rotating part of the rotary joint, and the bottom end of the discharge tube is sealed and fixedly connected to the fixed part of the rotary joint.

[0028] like Figure 1 As shown, a glue-feeding mechanism for a multi-point glue-feeding mold includes a support base 1, on which an angle-adjustable multi-point glue-feeding component and a speed-controllable glue-feeding component are sequentially arranged.

[0029] like Figure 1 and 3As shown, the angle-adjustable multi-point glue dispensing assembly includes a rotary driver, a glue dispensing tube 2 rotatably mounted on the top of the support base 1, a distributor 3 fixedly connected to the bottom of the glue dispensing tube 2, and four glue dispensing nozzles 4 sequentially fixedly connected to the bottom of the distributor 3 and arranged in a ring.

[0030] like Figure 3 and Figure 4 As shown, the driver includes a drive motor 6 fixedly mounted on the side wall of the fixed cover 5, a driving bevel gear 7 fixedly mounted on the output shaft of the drive motor 6, and a driven bevel gear 8 fixedly mounted on the upper part of the glue delivery tube 2. The output shaft of the drive motor 6 passes through one side of the fixed cover 5. The driving bevel gear 7 and the driven bevel gear 8 mesh with each other and are both located inside the fixed cover 5. Specifically, the drive motor 6 controls the driving bevel gear 7 to rotate, and then the driven bevel gear 8 meshing with the driving bevel gear 7 will drive the distributor 3 at the bottom of the glue delivery tube 2 to rotate. This makes it easy to flexibly adjust the glue injection angle of the four glue injection nozzles 4 on the distributor 3, so as to better meet the different glue injection point requirements of different multi-point glue injection molds.

[0031] like Figure 1-3 As shown, the speed-controlled glue feeding assembly includes a feeder cylinder 9 with a feed hopper 11 fixedly connected to one end of the top, a speed drive, a glue feeding screw 10 rotatably installed inside the feeder cylinder 9, and a discharge pipe 12 fixedly connected to one end of the bottom of the feeder cylinder 9.

[0032] like Figure 1 and 5 As shown, the bottom of the feeder cylinder 9 and the top of the support base 1 are welded with the same H-shaped bracket 14. The speed drive includes a frequency converter 15 fixedly installed on the side wall of the support base 1, a support plate 16 welded to the side wall of the H-shaped bracket 14, a speed motor 17 fixedly installed on the top outer wall of the support plate 16, a speed gear 18 fixedly mounted on the output shaft of the speed motor 17, and a transmission gear 19 fixedly mounted on the glue feeding screw 10. The speed gear 18 and the transmission gear 19 mesh with each other, and the frequency converter 15 is electrically connected to the speed motor 17. Specifically, the speed motor 17 controls the speed gear 18 to rotate, and then the transmission gear 19 meshing with the speed gear 18 drives the glue feeding screw 10 to rotate to perform glue feeding. The frequency converter 15 can flexibly adjust the speed of the speed motor 17, thereby flexibly adjusting the glue feeding speed. This facilitates flexible control of the glue feeding speed of the four glue inlets 4, which can better meet the glue feeding requirements of different multi-point glue feeding molds.

[0033] like Figure 1As shown, the top end of the glue feeding tube 2 passes through the top of the fixed cover 5. A rotary joint 13 is provided between the glue feeding tube 2 and the discharge tube 12. The top end of the glue feeding tube 2 is sealed and fixedly connected to the rotating part of the rotary joint 13, and the bottom end of the discharge tube 12 is sealed and fixedly connected to the fixed part of the rotary joint 13. Specifically, through the switching effect of the rotary joint 13, the normal glue feeding operation of the glue feeding tube 2 in the rotating state can be guaranteed.

[0034] In summary: First, during the installation and debugging process, the drive motor 6 controls the rotation of the active bevel gear 7. Then, the driven bevel gear 8, which meshes with the active bevel gear 7, drives the distributor 3 at the bottom of the glue delivery tube 2 to rotate. This makes it easy to flexibly adjust the glue injection angle of the four glue injection nozzles 4 on the distributor 3, so as to better meet the different glue injection point requirements of different multi-point glue injection molds.

[0035] Secondly, during use, the adhesive required for the multi-point injection mold is added from the feed hopper 11 into the feeder cylinder 9. At this time, the speed changer 17 controls the speed changer 18 to rotate, and then the transmission gear 19 meshing with the speed changer 18 drives the glue feeding screw 10 to rotate for glue feeding. The delivered adhesive will enter the glue feeding pipe 2 from the discharge pipe 12 through the rotary joint 13. After being divided by the distributor 3, the adhesive is evenly fed into the four injection nozzles 4. The speed of the speed changer 17 can be flexibly adjusted by the frequency converter 15, thereby flexibly adjusting the glue feeding speed. This makes it easy to flexibly control the glue feeding speed of the four injection nozzles 4, which can better meet the glue feeding needs of different multi-point injection molds.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model.
