Embodiment Construction
[0024] Such as figure 1 The opposite opening and closing mechanism of the two-plate injection mold shown includes a fixed mold, a stripping plate 1, a moving mold in the same direction, a moving mold in the opposite direction and linkage 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 moving mold in the same direction 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 invention discloses a two-plate type opposite opening and closing mechanism for an injection mold. The opposite opening and closing mechanism comprises a fixed mold, a demolding plate connected with the back end of the fixed mold, a same-direction moving mold, an opposite moving mold and a linkage component, wherein a cavity is defined by the fixed mold and the demolding plate; the same-direction moving mold abuts against the back end surface of the demolding plate, and a push hole which is through in the front-and-back direction is formed in the same-direction moving mold; the opposite moving mold is located behind the same-direction moving mold, and a push rod is arranged on the opposite moving mold and can penetrate through the push hole so as to push the demolding plate; the linkage component is connected with the same-direction moving mold and the opposite moving mold, so that the opposite moving mold and the same-direction moving mold are linked oppositely under the drive of external force. According to the mechanism, an integrated moving mold is divided into the same-direction moving mold and the opposite moving mold, and the two parts are oppositely and synchronously linked while mold opening, so that the demolding plate and a product are pushed out by the aid of the push rod, the working efficiency is greatly improved, and time is saved. The mechanism can be applied to molding.
Description
technical field [0001] The invention relates to the field of casting molds, in particular to a two-plate injection mold facing opening and closing mechanism. 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 is to provide...
