Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to an injection mold which is convenient for taking out injection molded parts. Background Art

[0002] Injection molding, also known as injection molding, is a molding method that combines injection and molding. The advantages of injection molding are fast production speed, high efficiency, automated operation, a wide variety of colors, shapes from simple to complex, sizes from large to small, and precise product size. The product is easy to update and can be made into complex-shaped parts. Injection molding is suitable for mass production and complex-shaped products and other molding and processing fields.

[0003] The molds can be divided into two types: left-right opening and closing and top-down opening and closing. The left-right opening and closing mold has an ejector mechanism on the side of the template, so that the injection molded parts can be ejected. However, most of the injection molds that open top-down do not have an ejector mechanism, making it difficult to remove the injection molded parts from the mold.

[0004] Therefore, how to provide an injection mold that is convenient for taking out the injection molded parts to solve the problems existing in the prior art is of great significance to its application. Utility Model Content

[0005] In view of this, the purpose of the present application is to provide an injection mold that is convenient for removing injection molded parts, so as to solve the problem that most injection molds with upper and lower mold openings are not equipped with an ejection mechanism, making it difficult to remove the injection molded parts from the mold.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] An injection mold for convenient removal of injection molded parts, comprising a lower mold plate and an upper mold plate, a positioning guide column is installed on the side of the top of the lower mold plate, the upper mold plate is slidably connected to the positioning guide column, an upper mold core is installed at the bottom of the upper mold plate, a support plate is provided in the middle of the top of the lower mold plate, and a lower mold core is installed at the top of the support plate;

[0008] A second hydraulic sleeve is installed in the middle of the top of the lower template, and a push rod is slidably connected to the top of the second hydraulic sleeve. A first hydraulic sleeve is installed on the outer side of the support plate, and a movable gear rod is slidably connected to the top of the first hydraulic sleeve. The bottom end of the first hydraulic sleeve is connected to the second hydraulic sleeve through a connecting pipe.

[0009] Preferably, a fixed gear rod is installed at the bottom end of the upper template, a support rod is installed on the side of the support plate, the end of the support rod is rotatably connected to a gear, and the gear and the movable gear rod are both meshed and connected with the gear.

[0010] Preferably, a top block is installed at the top of the ejector rod, and a hollow groove is opened at the top of the lower mold core, and the ejector block is matched with the hollow groove.

[0011] Preferably, the fixed gear rod and the movable gear rod are parallel to each other.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model facilitates the removal of injection molded parts by arranging a push rod. When in use, when the mold is opened, the upper template moves upward, the upper template drives the gear to rotate through the fixed gear rod, the gear drives the movable gear rod to move downward, and the movable gear rod presses the hydraulic oil inside the first hydraulic sleeve into the second hydraulic sleeve through the connecting pipe. At this time, the push rod is pushed upward, thereby ejecting the injection molded part out of the mold. Compared with the existing mold, the utility model can automatically eject the injection molded part in the mold in the opening mode, so that the injection molded part is convenient to take out.
