Description

Technical Field

[0001] This utility model relates to the field of injection molding machine technology, and in particular to an injection movable plate for an electrofusion injection station. Background Technology

[0002] The injection platen is one of the core components of the injection unit in an electrofusion injection molding machine. A servo motor and a built-in drive shaft need to be installed on this structure. To ensure stable motor operation, reduce vibration, and guarantee transmission accuracy, sufficient rigidity is required to support the weight of the servo motor and pulley assembly, and to prevent deformation during operation. During the injection molding process, the stable rotation of the screw is a crucial factor in ensuring uniform melt flow. Therefore, it is essential to ensure precise alignment of the motor shaft, pulley shaft, and drive shaft; otherwise, wear on the screw and bearings will increase, affecting plasticization uniformity and ultimately impacting product quality.

[0003] Chinese patent document CN219055233U, published on May 23, 2023, discloses an electrofusion structure for an injection molding machine, including a servo motor and a splined drive shaft. The servo motor is connected to a support frame via a mounting plate, and an adjustment mechanism is provided between the mounting plate and the support frame. The splined drive shaft is rotatably connected to the support frame, and the output shaft of the servo motor is connected to the splined drive shaft via a belt drive assembly. This electrofusion structure has a complex installation process. The mounting plate for the servo motor and the support frame for the drive shaft are independent parts, requiring screw connections. This not only increases the installation steps but also reduces alignment accuracy and increases wear on the belt and bearings.

[0004] Therefore, further improvements are necessary. Utility Model Content

[0005] The purpose of this invention is to provide a simple, stable, low-material-consumption, easy-to-process, and low-cost injection plate for an electrofusion injection station, so as to overcome the shortcomings of the prior art.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] See Figures 1-6 This invention relates to an injection plate for an electromelting injection station, comprising a mounting base 1, a mounting cylinder 2, and a support frame 3. A support portion is provided between the mounting base 1, the mounting cylinder 2, and the support frame 3. The mounting base 1 integrally supports and connects the mounting cylinder 2 and the support frame 3 via the support portion. The support frame 3 is integrally connected to the upper two sides of the mounting cylinder 2. This structure assembles the servo motor, pulley assembly, and drive shaft into a single unit, achieving machine modularization, simplifying manufacturing and assembly steps, reducing errors and rework, and improving production efficiency. It also reduces installation steps for components, improves overall alignment, has good rigidity, reasonable distribution of support ribs, maintains good stability, and features a simple structure, low material consumption, convenient processing, and low manufacturing cost.

[0025] The support includes a first support rib 4 connected to the left and right sides of the mounting cylinder 2 and a second support rib 5 connected to the bottom of the mounting cylinder 2. The lower ends of the first support rib 4 and the second support rib 5 are respectively connected to the mounting base 1, and the upper end of the first support rib 4 is connected to the support frame 3. The first support rib 4 plays the role of consolidating the support frame 3, and the second support rib 5 plays the role of consolidating the mounting cylinder 2.

[0026] The two support frames 3 are connected by a reinforcing rib 6. The lower end of the reinforcing rib 6 is connected to the top of the mounting cylinder 2. The support frame 3 needs to withstand the force and torque of the motor during operation and avoid vibration and deformation. Therefore, the support frame 3 needs to have sufficient rigidity. The reinforcing rib 6 in the middle can effectively reduce the deformation of the support frame 3 when under force, improve the overall rigidity, and improve stability.

[0027] The mounting cylinder 2 is provided with bearing mounting holes 7 for mounting the drive shaft, and the support frame 3 is provided with fixing holes 8 for mounting the motor mounting plate. The servo motor is connected to the support frame 3 through the motor mounting plate. The output shaft of the servo motor is connected to the driving pulley of the pulley set, and the driven pulley of the pulley set is connected to the drive shaft. The bearing mounting holes 7 can improve the alignment of the pulley set and the drive shaft.

[0028] The top of the mounting cylinder 2 is provided with an oil inlet hole 9 for adding lubricating oil. The oil inlet hole 9 is connected to the bearing mounting hole 7. A bearing is installed between the bearing mounting hole 7 and the drive shaft. Adding lubricating oil through the oil inlet hole 9 can lubricate the bearing, greatly reducing bearing wear and extending its service life.

[0029] The mounting cylinder 2 is located in the middle of the injection plate. The root 10 of the support frame 3 extends towards the middle of the injection plate and connects to the mounting cylinder 2, so that the gravity from the servo motor can be evenly distributed in the mounting cylinder 2 and the stress is dispersed. The mounting cylinder 2 is a cylindrical cylinder.

[0030] A connecting rib 11 is connected between one side of the reinforcing rib 6 and the top of the mounting cylinder 2, which further improves the rigidity of the support frame 3.

[0031] One end of the support frame 3 extends upward, and a clearance space 12 is formed between the two support frames 3 to avoid the installation of the motor.

[0032] A cavity 13 is provided in the middle of the bottom of the mounting base 1. Under the premise of meeting the rigidity requirements, the cavity 13 is reasonably set, which can reduce the material consumption of the moving plate of the launching platform and make the thickness of the surrounding ribs uniform, thus avoiding casting defects caused by casting.

[0033] The bottom of the mounting base 1 is provided with a limiting boss 14 for positioning the mounting slider. The electromelting injection station is set on the injection molding machine and includes an injection station base. The injection station base is provided with a linear guide.
