Technical Field

[0001] This utility model relates to the field of injection molding equipment technology, specifically a multi-component injection molding machine. Background Technology

[0002] Injection molding machines are the main molding equipment used to make various shapes of plastic products from thermoplastic or thermosetting plastics using plastic molds. The injection system is one of the most important components of an injection molding machine. Its function is to heat and plasticize a certain amount of plastic within a specified time during one cycle of the injection molding machine, and then inject the molten plastic into the mold cavity through a screw under certain pressure and speed.

[0003] In actual operation, after the injection components and injection tubes are installed, it is difficult to adjust their height later, and it is difficult to accurately ensure that the nozzle of the injection tube is closely aligned with the gate of the mold. It is also inconvenient to adjust the center distance between the two injection tubes to meet various injection conditions. At the same time, the existing equipment is not conducive to improving the fit between the nozzle of the injection tube and the gate of the mold, thereby ensuring the stability during injection.

[0004] Therefore, we propose a multi-component injection molding machine. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1: Please refer to Figure 1-6 This utility model provides a technical solution: a multi-component injection molding machine, including a frame 1, an adjustment platform 2, an injection tube 3, and an injection component 4. The injection component 4 has an existing structure, consisting of a screw, a screw drive device, and an injection cylinder. Its purpose is to allow the molten material to be discharged from the nozzle of the injection tube 3. The adjustment platform 2 is symmetrically arranged inside the frame 1, the injection component 4 is arranged on the adjustment platform 2, and the injection tube 3 is arranged at one end of the injection component 4. The injection component 4 is used to push the material inside the injection tube 3. The bottom of the frame 1 is symmetrically arranged with lifting components 5, which are multiple telescopic cylinders distributed at both ends of the frame 1. The telescopic cylinders are telescopic hydraulic cylinders or telescopic air cylinders, preferably telescopic hydraulic cylinders. The top of the lifting component 5 is fixedly installed with a lifting support platform 6, and the lifting support platform 6 is provided with an adjustment component 7 for adjusting the left and right movement of the adjustment platform 2.

[0026] It also includes an adjustable injection head 8, which is a tubular structure. The adjustable injection head 8 is slidably inserted into the nozzle of the injection tube 3. The injection tube 3 is provided with a fine-tuning component 9, which is used to drive the adjustable injection head 8 to move along the axial direction of the injection tube 3.

[0027] Example 4: The adjustment assembly 7 includes an adjustment motor 701, an adjustment screw 702 is fixedly installed at the output end of the adjustment motor 701, a screw hole that cooperates with the adjustment screw 702 is opened in the adjustment platform 2, guide rods 703 are symmetrically fixedly installed on the lifting support platform 6, guide holes that cooperate with the guide rods 703 are opened in the adjustment platform 2, and multiple sliding balls 10 are rolled and engaged at both ends of the bottom of the adjustment platform 2 so that the adjustment screw 702 can be rotated by turning on the adjustment motor 701. The adjustment screw 702 is a high-precision ball screw. After the adjustment screw 702 rotates, the adjustment platform 2 can be moved left and right by the guide rod 703 and the support of the sliding balls 10, thereby enabling the injection tube 3 to move left and right.

[0028] Example 6: The fine-tuning component 9 includes a ring frame 901, which is fixedly installed at the end of the injection tube 3 by welding. A fine-tuning motor 902 is fixedly installed inside the ring frame 901. A fine-tuning screw 903 is fixedly installed at the output end of the fine-tuning motor 902. A connecting frame 904 is fixedly installed at the end of the adjustable injection head 8. One end of the connecting frame 904 is sleeved on the fine-tuning screw 903. A screw hole that cooperates with the fine-tuning screw 903 is opened inside one end of the connecting frame 904. The fine-tuning screw 903 is a high-precision ball screw so that by turning on the fine-tuning motor 902, the rotation of the fine-tuning screw 903 can apply a thrust to the connecting frame 904, which can then drive the adjustable injection head 8 to move. This allows the adjustable injection head 8 to slide inside the nozzle of the injection tube 3, thereby ensuring that the adjustable injection head 8 is tightly attached to the mold gate and improving the adhesion.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention.
