Description

Technical Field

[0001] The utility model belongs to the technical field of injection molds, in particular to a guide structure of an injection mold. Background Art

[0002] Injection mold, also known as injection molding mold, is a tool used for injection molding and is a commonly used mold in industrial production. Injection molding is a process of heating the material to a molten state, then injecting the molten material into the mold through an injection molding machine, and molding it into a product of the desired shape and size after cooling. The plastic mold is usually composed of a movable mold and a fixed mold. The movable mold is installed on the movable template of the injection molding machine. During the use of the injection mold, a guide mechanism is generally required to limit and guide its moving direction.

[0003] The utility model patent with patent application publication number 202321112150.2 discloses a guiding structure of an injection mold, including a bottom plate, a bottom plate fixedly connected to a bottom mold, an upper mold arranged on the top of the bottom mold, a top plate fixedly connected to the top of the upper mold, and sliding rods fixedly connected to the four corners of the top of the bottom plate. The top of the sliding rod extends to the top of the top plate, a first spring is sleeved on the bottom of the surface of the sliding rod, a support plate is sleeved on the surface of the sliding rod and located at the top of the first spring, a buffer seat is fixedly connected to the top of the bottom plate and located between the two sliding rods, and pressure blocks are arranged on the front and rear sides of the inner cavity of the buffer seat. The problem that the guiding structure of the existing injection mold has no buffering function and limiting function is solved by the coordinated use of the bottom plate, the bottom mold, the upper mold, the top plate, the sliding rod, the first spring, the support plate, the buffer seat, the limit assembly, the pressure block, the second spring, the lifting block, the pressure wheel and the slot.

[0004] According to the above patent, there is a guide structure for an injection mold, and in actual use, there is a lack of buffer between the upper mold and the lower mold. When the driving part is damaged, it is easy for the upper mold to fall freely and collide with the lower mold, resulting in excessive force between the molds, which can easily cause damage to the molds and reduce the safety of the guide structure of the injection mold. For this reason, we propose a guide structure for an injection mold. Utility Model Content
