Description
Technical Field
[0001] This utility model relates to the field of mold angled ejector technology, specifically to an angled ejector device for a narrow position in a mold. Background Technology
[0002] A mold ejector is a demolding tool used in plastic injection molds or casting molds. It is mainly used to help remove complex-shaped workpieces or workpieces with recesses or dead corners from the mold. Its working principle is to use a certain force or thrust to push the workpiece in the mold through the ejector device so as to successfully demold it. It is a mechanism used in mold design to form the internal barbs of the product. Injection molds inject heated and molten plastic into the mold cavity under high pressure, and then cool and solidify it to obtain the molded product. In the production process of injection molded products, the injection molded part is difficult to remove from the mold cavity. The ejector structure can be used to help remove the injection molded part from the mold.
[0003] For small-sized barbed injection parts, the installation space for angled ejector devices is limited. Conventional angled ejector devices are difficult to install and disassemble, requiring significant time for inspection and maintenance, greatly reducing work efficiency. Furthermore, different molded barbed shapes within narrow spaces require different angles for the ejector. Conventional angled ejector devices are difficult to adjust, lacking flexibility and failing to effectively meet usage needs. Deviations in the angle can reduce product quality. Additionally, they are ineffective at demolding during ejection. To address these issues, a new angled ejector device for narrow mold locations is proposed. Utility Model Content
[0004] To address the aforementioned technical problems, a slanted ejector device for narrow mold locations is provided. This solves the issues raised by current methods for installing slanted ejector devices on smaller-sized undercut injection molded parts. These methods address the limitations of conventional slanted ejector devices, such as limited installation space, difficulty in installation and disassembly, and the time-consuming nature of maintenance and repairs, which significantly reduces work efficiency. Furthermore, the different shapes of the undercuts required for molds with varying narrow spaces necessitate different slanted ejector angles. Conventional slanted ejector devices are difficult to adjust, lack flexibility, and struggle to effectively meet usage needs. Deviations in the slanted ejector angle can reduce product quality. Additionally, slanted ejector devices often fail to effectively facilitate product demolding during ejection.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a slanted ejector device for narrow positions of a mold, comprising a worktable, with mounting plates fixedly connected to both the left and right ends of the upper side of the worktable; connecting rods fixedly connected to both the upper and lower ends of the right side of the left mounting plate; a fixed mold fixedly connected to the right side of the two connecting rods; a slanted ejector groove extending through the lower right end of the fixed mold; a second push rod fixedly installed at the center of the left side of the left mounting plate; the output end of the second push rod extending through the left side of the left mounting plate and fixedly connected to a connecting plate; a T-shaped slide rail fixedly connected to the lower right end of the connecting plate; a slanted ejector assembly slidably connected to the surface of the T-shaped slide rail; the slanted ejector assembly including a mounting support; the interior of the mounting support slidably connecting to the surface of the T-shaped slide rail; and a first fixed...

A top block is fixedly connected to the right side of the threaded rod. An arc-shaped groove is formed at the rear left end of the installation groove. An adjustment groove is formed through the front left end of the installation groove. An adjustment bolt is slidably connected to the inside of the adjustment groove. An adjustment rod is fixedly connected to the left side of the rotating block. The end of the adjustment bolt passes through the front side of the adjustment rod and engages with the inside of the arc-shaped groove.
[0006] Preferably, a feeding port is provided through the center of the upper side of the workbench, and support legs are fixedly connected to the four corners of the lower side of the workbench.
[0007] Preferably, a first push rod is fixedly installed at the center of the right side of the mounting plate at the right end, and the output end of the first push rod passes through the right side of the mounting plate at the right end and is fixedly connected to a connecting bracket.

Extending to the right side of the fixed mold 10, the product is effectively ejected. The inclined ejector assembly 15 includes a mounting support 1501. The interior of the mounting support 1501 is slidably connected to the surface of the T-shaped slide rail 14.
