Description

Injection molding machine toggle clamping device

technical field

The present invention relates to a toggle clamping device for an injection molding machine, especially a device that is not only simpler in its overall structure and composition, but also more convenient in its operation and use, and can further increase its overall structure. Practical toggle clamping device for injection molding machines.

Background technique

A large number of various plastic products appear in our daily life, from cups and storage boxes to the shells of various home appliances, and even the exterior parts of automobiles and motorcycles can be made of plastic materials, so plastic products have been used with Our daily life and even industrial production and commercial activities are closely related, and most of the items that use plastic materials as raw materials must be formed by plastic injection molding machines.

Among them, such as the US Bulletin No. 5,252,286 on October 12, 1993, "CLOSING UNIT FORA DOUBLE TOGGLE MOLDING APPARATUS AND METHOD" is a common plastic injection molding machine. Please refer to the existing structural diagram shown in Figure 7. The injection molding The machine 9 includes a machine table 91, four horizontal parallel guide pillars 92 are arranged above the machine table 91, and the guide pillars 92 pass through a fixed template 93, a movable template 94 and a base plate [closing or reaction plate ] 95, the fixed template 93 is fixed on the machine platform 91, one end of the guide post 92 is fixed on the fixed template 93, the movable template 94 can slide along the guide posts 92, and the lower end of the movable template 94 is set There is an adjustment structure 941 for adjusting its inclination angle. When the movable template 94 is away from or close to the fixed template 93, the mold opening and closing actions are generated. The base plate 95 is also fixed on the machine table 91, and the other end of the guide post 92 Fixed on the base plate 95, the two toggle mechanisms 96 controlled by a pair of hydraulic cylinders 961 are connected to a hollow circular actuating plate [control ring] 97 to control the opening and closing of the movable template 94. In the mold state, the actuating plate 97 is located between the movable template 94 and the base plate 95, and passes through the four guide pillars 92, so that it can slide between the movable template 94 and the base plate 95, and the actuating plate 97 is guided When guiding, it is directly displaced on the guide columns 92, and one end of each toggle mechanism 96 is pivotally connected to the movable template 94, and the other end is pivotally connected to the base plate 95, and the middle position of the toggle mechanism 96 is set by a Connecting rod 962 is connected with this actuating plate 97, and these two hydraulic cylinders 961 are located at the left and right two sides of this actuating plate 97, and its piston rod is then connected with this movable template 94, and this actuating plate 97 is guided When guiding, slide on the four sliding sleeves 98. These sliding sleeves 98 are sleeved on the guide pillars 92 and fixed to the movable template 94, and can be displaced on the guide pillars 92 with the movable template 94, and can be moved on the movable template 94. The template 94 is respectively provided with an oil injection hole 942 for injecting lubricating oil corresponding to each of the sliding sleeves 98 (please also refer to FIG. 8 for an end view of the existing actuating plate).

However, although the above-mentioned plastic injection molding machine can achieve the expected effect of manufacturing various plastic products, it is also found in its actual use that the movable template and the actuating plate of this structure are all pierced on the four guide pillars. , using four guide pillars to support the displacement of the movable formwork and the actuating plate, so that the movable formwork and the actuating plate can be smoothly displaced on the guide pillars, between the movable formwork, the actuating plate and the guide pillars A sliding sleeve is required, and the movable formwork is suspended on the four guide pillars. In order to avoid the oblique friction of the movable formwork due to its weight being too heavy on the guide pillars during the displacement process, generally It is necessary to set an adjustment structure at the lower end of the movable formwork to support and adjust the inclination angle between the movable formwork and the guide column, and to guide it. It is also full of inconveniences in use.

The purpose of the present invention is achieved in this way, a toggle mold clamping device for injection molding machine, the injection molding machine is mainly provided with a base plate and a fixed template on the machine table, and a number of guide columns are used to pass between the base plate and the fixed template. Set the position, and an operating plate and a movable template are provided between the base plate and the fixed template, and a toggle mechanism is provided between the base plate and the movable template, and a hydraulic cylinder is provided on the operating plate , to use the actuating plate to control the opening and closing states of the movable formwork; where:

There are linear slide rails between the machine table, the operating plate and the movable formwork, and the guide columns, the operating plate and the movable formwork are not in contact with each other, so that the linear slide rails can be used to support the operating plate and the movable formwork. The weight of the movable formwork is supported by the linear slide rail when the movable plate and the movable template move, and at the same time, the linear slide rail provides guidance for linear movement.

The actuating plate forms a depression corresponding to each guide post.

The actuating plate forms perforations corresponding to each guide post for the guide post to pass through.

The movable template forms a concave portion corresponding to each guide post.

The movable template forms perforations corresponding to each guide post for the guide post to pass through.

From the above, the injection molding machine toggle mold clamping device of the present invention is mainly provided with a linear slide rail between the lower end surface of the actuating plate on the injection molding machine table and the machine table, and between the movable template and the machine table. There is also a linear slide rail between the machines, so that the moving plate and the movable template can respectively use the linear slide rail to support their weight, and at the same time use the linear slide rail for the linear sliding of the movable plate and the movable template; thus , not only its overall structure is simpler, but also more convenient in its operation and use, and can increase the overall practical value of the injection molding machine.
