Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to an inverted double-color mold buckle machine structure. Background Art

[0002] The injection mold is equipped with a pouring device on the fixed mold and an ejector device on the movable mold to eject the product when the mold is opened. However, since the gate and ejection part of the product are on different sides, the traces left will affect the appearance of the product.

[0003] The four corner pads between the fixed template and the movable template are provided with pads. The flip mold injection molding in the existing technology is convenient and simple, and can ensure the appearance of the product and effectively guarantee the product quality, but its operation stability and control accuracy still need to be improved, which affects the quality of the finished product.

[0004] For example, Chinese patent CN205238486U discloses a latching mechanism for an inverted two-shot injection mold. The fixed mold is provided with several small tie rods for limiting position. There are two latching devices, one on each side of the fixed mold and the other on the movable mold. The latching mechanism is L-shaped, with a clamping block at the top that drives the ejector panel when the movable mold moves downward a certain distance. A rectangular wedge at the bottom of the latching mechanism drives the support plate when the movable mold moves upward. In practice, when the mold is first opened, the base plate, mold C plate, and support plate move downward 200 mm together. The fixed mold is limited by the small tie rods. The latching mechanism, locked to the support plate, moves downward with the support plate and drives the ejector downward via the latching slider to achieve ejection. When the mold is closed, the ejector is reset by components such as the return pin.

[0005] However, in the prior art, when performing injection molding on an inverted two-color mold, the mold needs to be opened and inverted and closed for secondary injection molding. During this process, rapid demoulding and rapid and accurate mold closing for secondary injection molding are required to ensure the molding effect of the secondary injection molding, thereby ensuring the molding effect of the two-color mold.

[0006] For this reason, we urgently need to provide a kind of inverted double-color mold buckle machine structure. Utility Model Content
