The first type is a relatively early product, because it does not have refrigeration function, only heat preservation function, also known as heat preservation box. When in use, articles to be refrigerated must be put into a freezer for freezing and then put into a heat preservation box, and words with ice bags are put into the ice bags, so that the ice can be kept frozen in a short time. The advantages of the freezer are no electricity consumption, relatively low price, and the disadvantages are that heat preservation cannot be... less

Even for the same type of moulds, the initial and precision requirements are different due to different types of formed plastics. Therefore, the assembly drawing should be carefully studied and analyzed before assembly. The part drawing should understand the effect, characteristics and skill requirements of each part, and confirm the installation benchmark. After installation, the quality indexes of the products, the action precision of the moulds and various skill requirements in the use process are finally fully achieved.
1. Installation benchmark, installation benchmark can be roughly divided into:
(1) The main working parts in the plastic mould, such as core, cavity and insert, are taken as the installation reference parts, and other parts of the mould are all equipped with installation reference parts for manufacturing and installation.
(2) Trimming and installing with the template side base surface of the guide... less
