Description

Technical Field

[0001] The utility model relates to the technical field of injection molding equipment, in particular to a guiding device for an injection mold. Background Art

[0002] Injection mold is a tool for producing plastic products, and also a tool for giving plastic products a complete structure and precise size. Injection molding is a processing method used in mass production of certain parts with complex shapes. Specifically, it refers to injecting heated and molten materials into the mold cavity under high pressure, and obtaining a molded product after cooling and solidification.

[0003] The injection mold is mainly composed of an upper mold base, a lower mold and a guide device for the injection mold arranged between the upper and lower modules. When working, the upper mold base of the injection mold is moved downward along the guide device for the injection mold, and finally fits with the lower mold base. At this time, the external injection machine injects the heated and melted plastic particles into the interior of the molding groove through the injection hole opened at the upper end of the upper mold base. During the injection process, the injection machine applies a certain pressure to fill the entire molding groove with plastic, thereby realizing the injection molding work;

[0004] At present, in the process of injection molding, since the mold seat needs to fit accurately, it is necessary to guide the fitting process. However, the existing guide device for the injection mold wears out too much as the use time increases, which easily leads to problems of inaccurate guiding and jamming, and needs to be replaced regularly. However, the existing guide device for the injection mold is usually connected and fixed to the injection mold by welding, which results in a long time spent on disassembling and replacing the guide device for the injection mold. Some guide devices for injection molds are connected and fixed to the injection mold by fastening bolts. Although it is convenient to install and disassemble the guide device for the injection mold, the fastening bolts will rust and strip after long-term use, affecting the stability of the guide device for the injection mold. For this reason, we propose a guide device for the injection mold. Utility Model Content
