Double drive blow molding machine

The present invention provides a dual drive blow molding machine that is related to the molding mechanism of a blow molding machine.

A general blow molding machine is shown in FIG. 1. The blow molding machine 100 is mainly provided with a two-stage blow mold half 102 which is relatively horizontally displaceable on a base 101, and the blow mold half mold 102 is connected to each other. The rod mechanism 103 is coupled, and the base 101 further defines a vertically displaceable bottom mold 104 between the two blow mold halves 102. At the same time, the base 101 is further provided with a driving source 105, which is driven by a single drive. The source 105 drives and simultaneously drives the two link mechanisms 103 and the bottom mold 104, and simultaneously drives the blow mold halves 102 and the bottom mold 104 to be displaced by the single drive source 105, thereby completing the blow mold half 102. The opening and closing mold and the bottom mold 104 are lifted and lowered; however, since the blow mold half 102 and the bottom mold 104 of the blow molding machine 100 have a certain volume and weight, the drive of each mold is simultaneously driven by a single driving source 105. The mode is extremely heavy load for the driving source 105, that is, the structural force during driving is completely concentrated on the main shaft of the driving source 105, so that destructive structural damage is easily generated, and thus the life of the structure is shortened; Avoiding shortening the life due to excessive load may have to be configured This is higher and can adapt to the heavy load of the drive source 105, but it will increase the overall mechanism cost, and affect the economic benefits; in view of this, the creator conceived and further research, and finally created a dual-drive blow Plastic molding machine.

The present invention provides a double-drive blow molding machine whose main purpose is to improve the general blow molding machine to drive the opening, closing and bottom mold lifting with a single driving source, and the load is too heavy, and the life of the mechanism is short.

In order to achieve the above object, the present invention provides a double-drive blow molding machine comprising: a body having a bottom plate; a first slide seat disposed on the bottom plate along a horizontal displacement and coupled to the first a forming mold half, the vertical horizontal direction is defined as a vertical direction; a first driving source is coupled to the first sliding seat through a first connecting rod group to drive the first sliding seat to be displaced on the bottom plate; a second sliding seat, The first sliding seat is horizontally displaceably disposed on the bottom plate and coupled to a second forming mold half B; a second driving source is coupled to the second sliding block through a second connecting rod group to drive the second sliding block The second sliding seat is displaced on the bottom plate; and a linkage unit includes a cam plate fixedly disposed on the linking member, and the two ends of the linking member are pivotally coupled to the first connecting rod group and the second connecting portion respectively The rod set, the first link set and the second link set yaw drive the linkage and the cam plate pushes against a bottom die unit to vertically move up and down.

The present invention drives the first sliding block and the second sliding block respectively through the two driving sources to drive the first sliding seat and the second sliding seat to drive the forming die to open and close the mold, and the first connecting rod group and the second connecting rod group The linkage unit is coupled to the linkage unit to drive the linkage unit to drive the bottom mold unit to move up and down, and the dispersing mechanism is forced to extend the service life of the overall mechanism.
