Description

An automatic pouring device for plastic molds

technical field

The utility model belongs to the technical field of moulds, in particular to an automatic pouring breaking device for plastic moulds. the

Background technique

With the rapid development of the plastic industry, plastic molds are used more and more widely. At present, most common molds adopt a single-part structure. Generally, the single-part structure can separate the coagulation material from the main channel, but it cannot achieve coagulation. Materials and products are separated. In actual production, in order to consider the convenience of condensate and product falling off, it is usually necessary to make the gate as small as possible, but it is inconvenient for the condensate to separate from the main channel when the mold is divided in this way, and the condensate needs to be manually processed. Therefore, there are risks in the production. In order to make the production safe, the production must be slowed down when this structure is adopted, so that the production efficiency is low and the overall cost is increased. the
