Description

The lotus open switch mold mechanism in the glassware press

technical field

The invention relates to a mold device for manufacturing glassware, in particular to a lotus opening mold switch mechanism in a glassware press.

Background technique

With the rapid development of the economy and the continuous improvement of people's living standards, people's aesthetic needs are getting higher and higher. For example, glassware, which is indispensable in life, has also been transformed from a simple practical and durable type to a beautiful and practical type, that is, it has a certain degree of decoration. Producing such products requires making complex forming molds. At present, glassware mainly has two molding methods: blowing and pressing. In comparison, the press molding method is more efficient, but the shape and structure of the glassware is limited. For vessels with simple shapes, such as cylindrical cups, etc., the integral mold can be used; for products with complex shapes, the mold must be opened to remove the pressed product from the mold. This mold is called a split mold. A press equipped with a split die is called an open die press. The split molds used in China are all two open molds, that is, the glassware forming mold is composed of two parts, which are closed when pressing and forming, and then opened when taking parts. Compared with the integral mold, the two-part mold press can press glassware with a more complex structure (with a handle or cup body with convex and concave), such as beer cups, ice cream cups, etc.; but for glassware with more complicated structures, if two The molding machine cannot open the mold to take out the product. At this time, a three-opening or multi-lobe molding machine must be used, that is, the glassware forming mold is composed of three or more parts. The mold opening presses for forming these special-shaped glassware require more complex mechanisms such as switching molds and clamping molds.

In short, two-part molds and integral molds are generally used to press glassware in China. The integral mold is used to press glassware with a relatively simple shape, and the two-open mold press can be used to manufacture glassware with a slightly more complicated structure; Simple and monotonous in style, it is difficult to meet people's increasing aesthetic needs.
