Embodiment Construction
[0024] Such as figure 1 The shown two-plate injection mold opening and closing mechanism in the same direction includes a fixed mold, a stripping plate 1, a fast moving mold, a slow moving mold and driving components.
[0025] The fixed mold includes a certain template 12, and the front end of the fixed template 12 is connected with a positioning ring 13 by means of bolts, and the sprue sleeve 14 is positioned in the fixed template 12 by the positioning ring 13. The stripping plate 1 is in contact with the rear end face of the fixed plate 12, but it is not fixedly connected, but can be separated from each other. Stripping plate 1, fixed plate 12, sprue sleeve 14 and core 17 penetrating fixed plate 12 encircle the mold cavity of product.
[0026] The fast moving mold abuts against the rear end face of the stripping plate 1 and can be separated from the stripping plate 1. It includes a core fixing plate 15 and a support seat 16. The front end of the core fixing plate 15 abuts o...

The invention discloses a two-plate injection mold same-direction opening and closing mechanism. The mechanism comprises a fixed mold, a stripper plate, a quick movable mold, a slow movable mold and a driving component, wherein the stripper plate is connected with the rear end of the fixed mold; the fixed mold and the stripper plate define a mold cavity; the quick movable mold abuts against the rear end face of the stripper plate; a front-back through push hole is formed in the quick movable mold; the slow movable mold is located behind the quick movable mold and provided with a push rod, and the push rod can penetrate through the push hole to abut against and push the stripper plate; the driving component connects the slow movable mold and the quick movable mold and drives the slow movable mold and the quick movable mold to conduct coordinated movement in the same direction far from or close to the fixed mold; and during coordinated movement, the movement speed of the quick movable mold is higher than that of the slow movable mold. According to the two-plate injection mold same-direction opening and closing mechanism, a whole movable mold is divided into the quick movable mold and the slow movable mold, and the quick movable mold and the slow movable mold conduct coordinated movement in the same direction at different speeds during mold opening, so that it is guaranteed that the stripper plate and a workpiece are ejected out by the push rod through the speed difference between the two movable molds while mold opening, the working efficiency is greatly improved, and time is saved. The two-plate injection mold same-direction opening and closing mechanism can be applied to molding.
Description
technical field [0001] The invention relates to the field of casting molds, in particular to a co-directional opening and closing mechanism of a two-plate injection mold. Background technique [0002] Most of the existing two-plate mold opening and closing mechanisms use bolts to directly connect the support block and the support plate to realize the opening and closing of the movable template and the fixed mold, and then push the push rod to eject the workpiece. [0003] This mechanism generally has two separate steps when opening the mold, including the opening and separation of the movable template and the fixed mold, and the use of a push rod to eject the workpiece. Since the two steps are carried out separately, the continuity of production is not high, and the time of opening and closing the mold is wasted, and the production efficiency needs to be improved. Contents of the invention [0004] In order to solve the above problems, the object of the present invention ...
