Problems solved by technology
The above-mentioned technical solution can improve the production capacity of the equipment to a certain extent, but on the one hand, the cooling speed of the plastic product is too fast, which will lead to unstable product performance; on the other hand, it is necessary to increase the cooling equipment, which increases the production cost
[0004] The purpose of the present invention is to provide a blow molding machine for mold opening and closing and pressure holding mold, under the premise of ensuring the cooling time, improve the utilization rate of equipment and improve the current situation of unbalanced production

Embodiment Construction
[0019] In order to describe the technical content, structural features, achieved goals and effects of the present invention in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.
[0020] Such as figure 1 and figure 2 The rotary molding tool base shown is used in a blow molding machine. The rotary molding mold base includes a support base 100, a main shaft 200, a positioning plate 300, a molding module 400 and a synchronous driving member 500. The two support bases 100 are arranged opposite to each other along the horizontal direction, and the two ends of the main shaft 200 are respectively connected to a support base 100; The two positioning plates 300 are respectively located inside the two support seats 100, and the two positioning plates 300 are fixedly connected to the main shaft 200 respectively; several synchronous driving parts 500 are arranged on the opposite inner sides of the two positioning plates 300, ...

The invention discloses a rotary molding die frame. The rotary molding die frame comprises supporting seats, a main shaft, positioning plates, a molding assembly and synchronous drivers, the two supporting seats are relatively arranged along a horizontal direction, and the main shaft is connected to the supporting seats respectively; the two positioning plates are respectively positioned at the inner sides of the two supporting seats, and are respectively fixedly connected to the main shaft; the synchronous drivers are relatively arranged at the relative inner sides of the two positioning plates, and are uniformly arranged along the rotating direction of the main shaft; the molding assembly comprises first molding dies and second molding dies, the output ends of the synchronous drivers arranged on one of the positioning plates are respectively connected with the first molding dies, and the output ends of the synchronous drivers arranged on the other one of the positioning plates are respectively connected with the second molding dies; and the synchronous drivers drive the first molding dies and the second molding dies to relatively move in order to realize the die opening and die closing of the molding assembly. The rotary molding die frame improves the balance of a production line without shortening the cooling time of the molding assembly, so the device utilization rate is improved.
Description
technical field [0001] The invention relates to a mechanism for producing injection molding materials, in particular to a mold base used for mold opening and closing and pressure maintaining of a blow molding machine. Background technique [0002] The process of forming plastic products includes three operating steps: injection molding, cooling and blanking. Among them, the time spent in the cooling step is much longer than that of the injection molding step and the blanking step. When the mold is kept under pressure and cooled, the mechanisms for injection molding and blanking of the product are all in an idle state, resulting in a production line of molded plastic products. Poor balance and low equipment utilization. [0003] At present, the industry is also exploring how to reduce the time consumed by the cooling step. Some reduce the cooling time of the product in the mold, some use cooling gas to shorten the cooling time to improve cooling efficiency, and some repeat ...
