Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically to an automatic reset mold structure for ejection. Background Technology

[0002] Automatic reset molds with ejector structures are a key design for achieving efficient and automated production in injection molding. At their core, after the ejection system (such as ejector pins and ejector rods) completes its ejection action, the internal mold mechanism (usually a reset rod or reset spring) automatically pushes the ejector plate and all ejector pins back to their initial positions during mold closing, without requiring additional action from the injection molding machine or manual intervention. This design effectively avoids the risk of damage caused by ejector pins colliding with the cavity or core during mold closing due to failure to reset, greatly improving production safety and mold life, while ensuring the rhythm and stability of continuous production.

[0003] Chinese patent CN214872424U discloses a mold ejection device, including an injection molding machine body. After the injection molding machine body opens the mold, the moving mold moves the injection-molded product and the intermediate mold to the ejection position, causing the intermediate mold to automatically engage with the support plates on both sides. The support plates drive the intermediate mold to rise and separate from the moving mold. The moving mold then moves to make room for ejection, and the ejector mold located below rises to eject the product from the perforation, thereby facilitating material collection. This fully automated method improves production efficiency and reduces production costs. However, this device still has the following problems: After the device is fed, it needs to be driven by the feeding component to reset. For vulnerable parts such as the material strip terminals, too many steps will increase the risk of damaging the product.

[0004] Based on this, this utility model designs an automatic reset mold structure for ejection to solve the above problems. Utility Model Content

The automatic reset mechanism 3 includes an ejection assembly 31, an ejection transmission assembly 32, an automatic reset assembly 33, and an ejection drive assembly 34. The base 1, ejection assembly 31, automatic reset assembly 33, and ejection drive assembly 34 are all connected to the ejection transmission assembly 32. The ejection assembly 31 is used to eject the processed material, the ejection transmission assembly 32 is used to process the material and drive the ejection drive assembly 34 to the ejection assembly 31 and the automatic reset assembly 33. The automatic reset assembly 33 is used to automatically reset the ejection drive assembly 34 after the material is ejected, and the ejection drive assembly 34 is used to drive the ejection transmission assembly 32.

[0021] In this invention, the operator places the material strip on the feeding mechanism 2, which automatically feeds the material strip. Then, the ejector transmission assembly 32 processes the material strip. After processing, the ejector drive assembly 34 drives the ejector transmission assembly 32 to push the material strip out of the ejector transmission assembly 32. After ejection, the ejector drive assembly 34 drives the ejector assembly 31 to reset through the automatic reset assembly 33. This eliminates the need for the cylinder to eject twice to pull the terminal material strip, thus improving production efficiency and mold stability during the production process.

[0022] The ejection assembly 31 includes an ejector pin 311 and an ejection clamping plate 312; both the ejector pin 311 and the ejection clamping plate 312 are connected to the ejection transmission assembly 32.

The template 321 is fixedly connected to the lower end of the ejection rods 322. The ejection plate 323 is connected to the automatic reset assembly 33. The automatic reset assembly 33 includes a slider 331, a slider base 334, and a reset spring 335; the two sliders 331 are symmetrically arranged left and right; a first inclined surface 332 is provided on the slider 331; a slider base 334 is fixedly connected to the ejector plate 323; the slider base 334 abuts against the first inclined surface 332; the slider 331 is limited and slidably connected to the template 321; a second inclined surface 333 is provided on the lower side of both ends of the ejector plate 323; the ends of the two slider bases 334 that are far apart from each other are fixedly connected to one end of a reset spring 335, and the other end of the reset spring 335 is fixedly connected to the template 321.

The third cylinders 341 are fixedly connected to the template 321, and the drive end of the template 321 is fixedly connected to the base 1.

[0023] In this invention, the operator activates the third cylinder 341 to move the template 321 upward. The upward movement of the template 321, via the ejector plate 323, causes the ejector pins 311 and ejector clamps 312 to eject the processed material upward. Simultaneously, the slider base 334 pushes the two sliders 331 away from each other via the first inclined surface 332, compressing the reset spring 335. Until the ejector plate 323 slides downward via the second inclined surface 333, causing the ejector pins 311 and ejector clamps 312 to slide downward and reset, canceling the ejection of the material. After the template 321 resets, the reset spring 335 drives the slider 331 to reset. This achieves automatic reset of the ejector clamps 312 and ejector pins 311, automating and eliminating a set of actions, reducing the risk of mold pressing, and improving mold life and stability.
