Description

Technical Field

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

[0002] Injection molding, also known as injection molding, is a molding method that combines injection and molding. The advantages of injection molding are fast production speed, high efficiency, automated operation, a wide variety of colors, shapes from simple to complex, sizes from large to small, and precise product size. The product is easy to update and can be made into complex-shaped parts. Injection molding is suitable for mass production and complex-shaped products and other molding and processing fields.

[0003] An injection mold with an existing patent announcement number of CN219667319U utilizes a simplified fixing device to avoid the complicated operation process of the operator needing to install and remove the threaded rods one by one. The operator only needs to snap the upper mold and the lower mold together through the fixing device to ensure a stable groove connection between the upper mold and the lower mold, thereby improving work efficiency and ensuring the accuracy of the injection molding work.

[0004] However, the injection mold adapts the buckle block to the slot by rotating. During the process, the buckle block is obliquely embedded in the slot, which makes it difficult for the buckle to be embedded in the slot, causing inconvenience for the upper and lower molds and easily causing the buckle to break. Therefore, it does not meet the existing needs. We have proposed an injection mold for this purpose. Utility Model Content

[0005] The purpose of the utility model is to provide an injection mold to solve the problem that the injection mold proposed in the above background technology adapts the buckle block to the slot by rotating. During the process, the buckle block is obliquely embedded in the slot, which makes it difficult for the buckle to be embedded in the slot and easily causes the buckle to break.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an injection mold, comprising a lower mold, an upper mold is arranged above the lower mold, four fixing seats B are arranged on the outer wall of the lower mold near the top, four fixing seats A are arranged on the outer wall of the upper mold near the bottom, and the four fixing seats A are respectively vertically overlapped with the four fixing seats B, a connecting groove is arranged at the top of the fixing seat B, a connecting seat is arranged at the bottom end of the fixing seat A and is embedded in the connecting groove, a slot is arranged on the end surface of the connecting seat facing the lower mold, an insert block is embedded in the slot, a baffle is arranged at the bottom end of the insert block, a connecting rod is arranged at the end of the bottom end of the baffle away from the lower mold, a limit block is arranged at the end of the connecting rod outside the fixing seat B, a limit rod is arranged above the connecting rod outside the fixing seat B, and handles are arranged at both ends of the upper mold.

[0007] Preferably, a fixing block passes through the top end of the limiting rod, one end of the fixing block is connected to a fixing seat B, and a grip block is provided at the top end of the limiting rod.

[0008] Preferably, a movable groove is provided at one end of the bottom end of the connecting groove close to the lower mold, a guide groove is provided at the top end of the movable groove, and the insert block is slidably connected in the guide groove.

[0009] Preferably, a groove is provided at one end of the bottom of the movable groove away from the lower mold, a spring is provided in the groove, and the spring is sleeved on the connecting rod.

[0010] Preferably, a positioning block is provided at the bottom end of the limiting rod, every two fixing seats A are located at the same end of the upper mold, and an upper handle is provided between the two fixing seats A.

[0011] Preferably, a lower handle is provided below the upper handle, and both ends of the lower handle are respectively fixedly connected to the two fixing seats B, a plurality of positioning rods are evenly provided on the bottom side of the upper handle, and a plurality of positioning grooves are provided on the top side of the lower handle.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model lifts the grip block so that the limit rod no longer limits the limit block, so that its spring pushes the baffle plate and moves the insert block away from the connecting groove, so that the connecting seat can be embedded in the connecting groove, and then the limit block is pulled to make the limit block and the limit rod misaligned. At this time, the limit rod should slide down due to gravity, thereby limiting the movement of the limit block. At the same time, the limit block drives the baffle plate through the connecting rod to embed its insert block into the connecting groove and the slot to fix the upper mold. The connecting seat, the insert block, the baffle plate, the spring, the connecting rod, the limit block and the limit rod are used, so that the operator only needs to lift the grip block or pull the limit block to buckle and fix the upper mold and the lower mold, so as to meet the requirements of the stable groove connection of the upper mold and the lower mold, thereby improving the work efficiency and ensuring the accuracy of the injection molding work.
