Description

Technical Field

[0001] The utility model relates to the technical field of finish machining of thrust seats, in particular to a multi-station fixture for a thrust seat of an injection molding machine. Background Technique

[0002] At present, the finish machining of the thrust seat in the clamping part of an injection molding machine generally uses a single-station or double-station fixture for machining, that is, 1-2 workpieces are installed at one time by the same fixture and machined at one time. Because it involves machining different surfaces at the same time, and there may be factors such as mutual interference in tool feeding and tool cutting between different workpieces, it is usually very difficult to set more than 2 stations for such fixtures, and it is also very difficult to popularize them for multiple models.

[0003] The machining of large castings such as thrust seats is usually a very time-consuming process, involving multiple machining steps such as milling, drilling, and boring on multiple surfaces. Too few stations means low machining efficiency, and there will be continuous tool changing, frequent rotation of the worktable to change the surface, and multiple tool feeding actions. The low machining efficiency of a single process will have a negative impact on the entire process flow. If only the improvement is carried out for a single model of workpiece, then when the machine tool switches the types of workpieces to be machined, it will face the problems of replacing and recalibrating heavy fixtures, which is also very time-consuming and there are safety and quality risks. Therefore, a multi-station fixture for a thrust seat of an injection molding machine is proposed to solve the above-mentioned problems. Content of the Utility Model

[0022] Please refer to Figures 1 - 3 , a multi-station fixture for the thrust seat of an injection molding machine, including a fixture 1, a workpiece 9, and a workbench 10. A part mounting portion 2 is provided at the rear side of the fixture 1. The fixture 1 is mounted on the top of the workbench 10, and the workpiece 9 is mounted on the side of the part mounting portion 2.

[0023] In this embodiment, the part mounting portion 2 is composed of two equal and mutually perpendicular mounting plates, and the inner wall at the connection of the two mounting plates is set as an isosceles right triangle. A plurality of tool access holes 11 are provided in the middle of the mounting plates.

[0024] It should be noted that this design allows multiple workpieces 9 to be mounted on the same fixture, realizing multi-station processing, thereby significantly improving production efficiency. The inner wall design of the isosceles right triangle enhances the stability and structural strength of the mounting plates, ensuring that they are not easily deformed during high-intensity processing. The layout of the plurality of tool access holes 11 allows different tools to approach the workpiece from different angles, realizing complex processing requirements, and at the same time reducing the time for tool change and workpiece repositioning.

[0025] In this embodiment, a positioning hole 4 and four screw holes 5 are provided on both sides of a tool access hole 11 inside the mounting plate. After the middle part of the rear end face of the workpiece 9 is inserted into the tool access hole 11, a positioning pin 6 is inserted between the upper and lower parts of the workpiece 9 and the positioning hole 4.

[0026] It should be noted that the combination of the positioning hole 4 and the positioning pin 6 beside each tool access hole 11 ensures the precise positioning of the workpiece 9 during the machining process, prevents the movement of the workpiece caused by vibration or cutting force, thereby ensuring the machining accuracy. The four screw holes 5 provide a stable fixing point for the pressing plate 7, making the workpiece 9 more stable and reliable during the machining process.

[0027] In this embodiment, a pressing plate 7 is provided on the outer side of the workpiece 9, and screws 8 are threadedly connected between the pressing plate 7, the workpiece 9, and the screw holes 5.

[0028] It should be noted that the combination of the pressing plate 7 and the screws 8 provides a simple and effective fixing method, which can tightly press the workpiece 9 on the mounting plate.

[0029] In this embodiment, a counterweight 3 is installed at the top of the workbench 10 opposite to the part mounting portion 2, and a tool anti-collision groove 12 is also provided inside the mounting plate outside the screw holes 5.

[0030] It should be noted that the installation of the counterweight 3 helps to balance the overall weight of the fixture, reduce vibration and instability caused by uneven weight, thereby improving the smoothness and safety of the machining process. The tool anti-collision groove 12 is a preventive design used to provide buffering when the tool accidentally deviates from the predetermined path, preventing the tool from directly colliding with the mounting plate, thereby protecting the tool and the fixture from damage.

[0031] Beneficial effects:

[0032] For this multi-station fixture of the injection molding machine thrust seat, by designing the fixture 1 including the part mounting portion 2, the machining efficiency is significantly improved. The part mounting portion 2 is composed of two mounting plates that are perpendicular to each other and have isosceles right triangle inner walls. This innovative design not only stably supports the workpiece 9 but also enables the flexible operation of the tool through the tool access holes 11 opened in the middle, reducing the number of tool changes. The positioning holes 4 on both sides of the mounting plate are accurately aligned with the workpiece 9 through the positioning pins 6 to ensure the machining accuracy. The four screw holes 5, in combination with the use of the pressing plate 7 and the screws 8, effectively fix the workpiece 9 and prevent displacement during the machining process. In addition, the counterweight 3 installed on the workbench 10 balances the overall weight of the fixture 1 and improves the operation stability. The tool anti-collision groove 12 inside the mounting plate further protects the tool and reduces the collision risk during the machining process.

[0033] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
