Description

Technical Field

[0001] This utility model relates to the field of plastic mold processing technology, specifically to a plastic mold surface milling device. Background Technology

[0002] Plastic molds are a type of combined mold used for compression molding, extrusion molding, injection molding, blow molding, and low-foaming molding. The coordinated changes of the mold's punch, die, and auxiliary molding system can produce a series of plastic parts of different shapes and sizes. During the processing of plastic molds, grinding and milling are necessary. Grinding and milling not only increases the aesthetics of plastic molds but also improves the corrosion resistance and wear resistance of the plastic mold surface.

[0003] A search revealed that patent application number 202321191039.7 discloses a plastic mold surface milling device, comprising a main body. The main body includes a protective box, with a base fixedly connected to the bottom of the protective box. A waste trough is provided at the top of the base, and a guide plate is fixedly connected to the bottom of the waste trough. By setting an L-shaped support clamp, an electric telescopic rod, and a first motor, the device can be adjusted according to molds of different sizes. The waste trough and guide plate facilitate the collection of debris generated during milling. The third motor, mesh plate, and fan blades enable overall surface cleaning of the mold. The cylinder and air pipe enable local cleaning of the processed areas of the mold to prevent debris residue. The sliding rod provides support and limit for the L-shaped support clamp, preventing displacement and effectively enhancing the practicality of the device.

[0004] While the milling equipment with an external air pipe configuration described in the aforementioned application documents can handle processing waste through negative pressure adsorption, it has significant limitations in practical applications: First, the equipment uses a fixed head design, allowing only single-plane milling of the mold at a fixed bottom position during processing. This lack of multi-axis linkage capability results in insufficient processing flexibility, making it difficult to meet the high-precision processing requirements of complex curved surfaces or irregularly shaped molds. Second, for commonly used high-strength steel molds, which are heavy and structurally complex, the fixed worktable design of existing equipment not only makes mold positioning and adjustment difficult but also increases safety risks during mold changing, severely impacting processing efficiency. These structural defects mean that this technology cannot guarantee processing accuracy or improve production efficiency when dealing with diverse mold processing needs.

[0005] Therefore, we propose a surface milling device for plastic molds. Utility Model Content

The limiting clips are L-shaped clips, and a disc is fixedly installed at the bottom of the limiting clips, with a limiting pin inserted in the disc.

[0014] The limiting card structure facilitates the limiting of the mold inside from the four corners, while the limiting pins ensure efficient limiting effect and convenient operation.
