Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of injection molding machine, specifically a novel glue injection structure and injection molding machine. BACKGROUND

[0002] Lead screw transmission and synchronous pulley transmission are widely used in injection molding machines due to their convenience, efficiency and controllability, especially for realizing glue injection function in electric injection molding machines. The existing glue injection structure generally uses a joint casting body structure. The joint casting body of the injection table has the problems of relatively large volume, complex processing, and can only be matched with specific lead screws and motors, poor adaptability, etc. The joint casting body of the injection table has many types, increasing the material management cost and difficulty of producers, resulting in high production cost and difficult material management.

[0003] The traditional joint casting body of the injection table is only suitable for specific lead screws and motors, limiting its versatility. Therefore, there is an urgent need for a small-sized, highly compatible glue injection structure to reduce costs and improve flexibility. SUMMARY

[0004] The utility model provides a novel glue injection structure and injection molding machine to solve the above technical problems. The structure is small and compact, significantly improving compatibility and reducing costs through modular design and adjustable bearing seat.

[0005] To achieve the above purpose, the technical scheme of the utility model is as follows:

[0006] A novel glue injection structure includes a joint casting body of the injection table, a lead screw bearing assembly, a bearing seat, and a screw barrel assembly. The screw barrel assembly is installed on the joint casting body of the injection table. The bearing seat is fixedly connected to the joint casting body of the injection table. The lead screw bearing assembly passes through the bearing seat and is connected to the screw barrel assembly.

[0007] The bearing seat includes a motor fixing structure and a bearing fixing structure. The motor fixing structure is connected to a motor assembly. The motor fixing structure adjusts the adaptive structure according to the model of the motor assembly. The bearing fixing structure adjusts the adaptive structure according to the specifications of the lead screw bearing assembly.

[0008] The bearing seat of the novel glue injection structure includes a motor fixing structure and a bearing fixing structure, which are separately modularized and replaceable, and the structure is compact. By adjusting the size of the motor fixing structure and the bearing fixing structure, different models of motors and lead screws are adapted, reducing the types of joint casting bodies of the injection table, significantly improving compatibility and reducing costs.

[0009] Further optimization scheme also includes a movable plate assembly. The screw barrel assembly is connected to the lead screw bearing assembly through the movable plate assembly. The lead screw bearing assembly converts rotary motion into linear motion, pushing the movable plate assembly and driving the screw barrel assembly to complete the glue injection action.

[0010] A further optimized solution includes a synchronous pulley assembly, which connects the lead screw bearing assembly and the motor assembly. The motor assembly drives the lead screw bearing assembly to rotate via the synchronous pulley assembly, and the rotation is converted into linear motion by the lead screw bearing assembly, thus driving the movable plate assembly forward or backward.

[0011] A further optimized design incorporates a T-shaped cross-section rotated 90°, with both ends connected to the motor assembly, the middle section passing through the lead screw bearing assembly, and one end connected to the injection molding unit. This integrated T-shaped structure of the bearing housing facilitates manufacturing, installation, and ensures uniform and reliable force distribution during lead screw movement.

[0012] An injection molding machine comprising the novel injection structure described above.

[0013] This utility model has the following technical advantages compared with the prior art:

[0014] 1. Modular bearing housing design: Through the separate motor fixing structure and bearing fixing structure, it can be adapted to multiple models of motors and lead screws, improve compatibility, reduce the types of injection molding assembly, and reduce material management costs;

[0015] 2. Simplified transmission and structure: The synchronous belt pulley assembly directly links the motor and the lead screw, and works with the movable plate assembly to achieve linear motion, resulting in a compact structure;

[0016] 3. Functional integration: The injection molding unit integrates all components, reducing processing complexity, making installation convenient and quick, and ensuring the stability of movement. Attached Figure Description
