Embodiment Construction
[0016] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0017] Such as Figure 1~2 As shown, an injection molding machine compression molding clamping mechanism includes an auxiliary template 1, a fixed template 3, a clamping compression cylinder 2, a mold 4, and components such as a directional valve for controlling the clamping compression cylinder 2, and the auxiliary template 1 is parallel to Since the fixed template 3 is arranged between the fixed template 3 and the mold 4, the clamping compression cylinder 2 is installed on the fixed template 3 to push the auxiliary template 1 to move back and forth so as to realize mold clamping and mold opening. There are four pull rods 5 in total at the top, bottom, left, and right in the hinged part of the machine. The auxiliary template 1 is threaded on the pull rods 5, and is fixedly connected with the piston rod of the clamping compression cylinder 2. ...

The invention relates to a compression forming mold-locking mechanism of an injection molding machine. The compression forming mold-locking mechanism of the injection molding machine is characterizedby comprising an auxiliary template, wherein the auxiliary template is arranged between a fixed template and a mold, the fixed template is provided with a mold-locking compression oil cylinder for pushing the auxiliary template to move back and forth so as to realize the mold closing and opening, and a bottom plate of the auxiliary template is provided with a supporting leg for supporting the auxiliary template. By arranging the auxiliary template and the mold-locking compression oil cylinder, a female mold of the mold is fixed on the front side of the auxiliary template, and the auxiliary template is pushed to move forwards by starting the mold-locking compression oil cylinder, so as to close the mold, thereby completing the injection compression forming action. The compression forming mold-locking mechanism is simple and reasonable in structure; and by virtue of the actions of the auxiliary template and the mold-locking compression oil cylinder, the injection pressure can be increased, the forming rate of a complicated structure plastic product can be effectively increased, and the compression forming mold-locking mechanism can be widely used for producing a large-sized product with high requirement for the injection pressure.
Description
technical field [0001] The invention relates to the technical field of injection molding machine product molding, in particular to an injection molding machine compression molding clamping mechanism for compression molding by using clamping force. Background technique [0002] With the continuous development of plastic processing engineering, more and more plastic products are used in industrial production. At the same time, the structure of plastic products is becoming more and more complex, and the technical requirements for existing injection molding machines are also getting higher and higher. For example, plastic trays, the characteristics of plastic trays are: relatively complex structure, thin and long flow channel, large flow-to-length ratio, high requirements for injection pressure of the machine, and low molding rate. For large pallets, it is difficult to effectively increase the molding rate even if the domestic general-purpose injection molding machine is modifi...
