Description

Technical Field

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

[0002] The guide device for injection molds is an important component of injection molds. It is mainly used to ensure the smooth opening and closing and precise positioning of the mold. Common guide devices include guide pins and guide sleeves. The guide pins are usually installed on the fixed plate of the mold, while the guide sleeves are installed on the movable plate of the mold. When the mold opens and closes, the guide pins slide in the guide sleeves to ensure the smooth operation of the mold and prevent the mold from shifting or deforming under high pressure. In addition, the guide device can also help protect the cavity and core of the mold to avoid damage caused by misalignment. The design and manufacture of the guide device need to take into account factors such as precision, wear resistance and impact resistance, because these characteristics directly affect the service life of the mold and the precision of the injection molded product. The guide device for injection molds plays a vital role in the design and manufacture of injection molds.

[0003] According to the search, the Chinese patent document, announcement number: CN217414726U, discloses that the utility model discloses a guide device for an injection mold, including an upper mold, the bottom of the upper mold is movably sleeved with the lower mold, the top of the upper mold is provided with a pressure block positioning groove, the inside of the pressure block positioning groove is provided with a pressure block fixing hole, the top of the upper mold is fixedly provided with a raw material injection port, the bottom of the upper mold is provided with a guide column groove, the bottom of the upper mold is provided with an upper mold groove, and the inside of the guide column groove is fixedly sleeved with a guide column. In the above scheme, the upper and lower molds are constantly opened and closed, and the guide column and the guide sleeve are prone to wear and deformation. At this time, the ball is used, and the lubricant is automatically replenished quantitatively during operation, which reduces wear and improves the service life.

[0004] During the use of the wire device, if the mold is damaged or a different model of injection mold needs to be replaced, the wire device lacks a design for quick replacement and disassembly of the mold, which may cause the loading and unloading time of the mold to be prolonged, thereby slowing down the production cycle and affecting the overall production efficiency.
