Description

Technical Field

[0001] The utility model belongs to the technical field of mold locking mechanisms for injection molding machines, in particular to a mold locking mechanism for injection molding machines. Background Art

[0002] Injection molding machine, also known as injection molding machine or injection machine, is a key equipment used to manufacture plastic products. It heats plastic particles to a molten state, then injects the molten plastic into a pre-designed mold under high pressure, and forms a plastic product with a specific shape and size after cooling. Injection molding machines are widely used in various industrial production, including automotive parts, electronic components, household appliances, packaging materials and other fields. The injection molding machine clamping mechanism is a key component inside the injection molding machine. It is mainly responsible for ensuring the accurate closure and retention of the mold during the injection molding process to ensure that the plastic melt is effectively formed in the mold cavity and can be firmly kept in the closed state of the mold after cooling until the finished product is taken out. The clamping mechanism usually includes a fixed mold plate, a movable mold plate and related driving components. The opening and closing movement of the mold is controlled by the synergistic action of these components. The existing injection molding machine clamping mechanism cannot quickly install the injection mold on the clamping mechanism.

[0003] For example, the utility model with announcement number CN218429792U discloses a locking mechanism for an injection molding machine, in which the template and the pad are connected by bolts, the pad is provided with a T-hole for accommodating the bolts, the template is provided with a T-slot and a T-block slidably connected to the T-slot on one side close to the mold, and the T-block is provided with a threaded hole screwed with the bolt. In this patent scheme, the locking mechanism for the injection molding machine needs to twist multiple mounting bolts to achieve the installation of the injection mold. Since multiple mounting bolts need to be twisted, the installation process is relatively complicated and takes a long time, which will increase downtime and reduce production efficiency. Utility Model Content

[0006] As a further improvement of the present invention, a control panel is arranged on the left side surface of the frame plate, and the electric push rod is electrically connected to the control panel.

[0007] As a further improvement of the present invention, installation components are welded and fixed on the left and right sides of the lower end of the frame plate, and the installation components include installation plates welded and fixed on the left and right sides of the lower end of the frame plate. Two installation holes corresponding to the front and rear positions are provided inside the two installation plates.

[0008] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0009] Firstly, by rotating the hand wheels on both sides counterclockwise in turn, the bidirectional screw rod is driven to rotate so that the installation blocks on both sides move away from each other. Then, the injection molds to be installed are placed on the upper ends of the two pallets in turn through external lifting equipment. Then, by rotating the hand wheels on both sides clockwise in turn, the bidirectional screw rod is driven to rotate and drive the installation blocks on both sides to move towards each other under the sliding restriction of the sliding groove and insert them into the installation grooves opened on the front and rear sides of the registered mold to realize the rapid installation of the injection mold. The installation of the injection mold is realized by simply rotating the hand wheel to drive the installation blocks to move toward each other. The installation process is simple and quick, which saves installation time and improves production efficiency.

[0010] Secondly, the anti-slip sleeves on the two hand wheels can prevent people from slipping when rotating the hand wheels, making people more stable when rotating the hand wheels, and can effectively improve the efficiency of installing the injection mold on the clamping mechanism.

[0011] Thirdly, the control panel is used to control the electric push rod to start operation, and the telescopic end drives the sliding plate to move to the right, so that the injection mold on the sliding plate contacts the injection mold on the frame plate. The upper and lower electric push rods drive the connecting column to apply pressure to the injection mold on the sliding plate, so that the injection mold is evenly stressed when locking the mold, which can significantly improve the production quality.

[0012] Fourthly, the clamping mechanism can be installed and fixed through the mounting holes on the mounting plate, so that the clamping mechanism of the injection molding machine will not run out of position during operation, thereby making the operation of the clamping mechanism of the injection molding machine more stable and improving the production quality.
