Abstract
Description
Technical Field
[0001] This utility model relates to the field of molds, specifically to an injection mold for producing small household appliance shells. Background Technology
[0002] Molds are various molds and tools used in industrial production to obtain desired products through methods such as injection molding, blow molding, extrusion, die casting, forging, smelting, and stamping. In short, molds are tools used to make shaped objects. These tools are composed of various parts, and different molds are composed of different parts. They mainly achieve the processing of the shape of objects by changing the physical state of the material being molded, and are often referred to as the "mother of industry".
[0003] In the production of plastic shells for small household appliances, molds are required to process and shape the plastic shells. Existing molds do not have automatic demolding functions. When using the molds, people need to demold manually, which is time-consuming, laborious, slow, and inconvenient. In addition, the mold cooling time is too long, and if it is not cooled, it will stick together, wasting time. Summary of the Invention
[0004] In view of the problems existing in the injection molds used for the production of small household appliance shells, this utility model is proposed.
[0005] Therefore, the purpose of this utility model is to provide an injection mold for the production of small household appliance shells, which solves the problem of not having an automatic demolding function.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] An injection mold for producing small household appliance casings includes a base, a fixed seat fixedly mounted on the top of the base, a partition fixedly mounted inside the fixed seat, a lower injection cavity fixedly mounted on the top of the partition, a top plate slidably mounted inside the lower injection cavity, a support rod fixedly mounted on the bottom of the top plate, a connecting plate fixedly mounted on the bottom of the support rod, an elastic telescopic rod fixedly mounted on the bottom of the connecting plate, the elastic telescopic rod being fixedly connected to the bottom of the fixed seat, a sliding groove fixedly opened on the top of the fixed seat, a bracket fixedly mounted on the top of the fixed seat, the bracket being slidably connected to the sliding groove, an upper injection cavity fixedly mounted on the bottom of the bracket, an injection pipe fixedly mounted inside the upper injection cavity, and water tanks fixedly mounted on both side walls of the lower injection cavity.
[0008] Preferably, a positioning block is fixedly provided at the bottom of the bracket, and multiple positioning grooves are fixedly provided at the top of the injection cavity, with the positioning grooves engaging with the positioning block.
[0009] Preferably, a water inlet is fixedly provided on the top of the water tank, and a drain outlet is fixedly provided on one side wall of the water tank, with the drain outlet passing through the fixing seat.
[0010] Preferably, a bearing is fixedly provided at the bottom of the injection cavity, and the bearing is slidably connected to the support rod.
[0011] Furthermore, a sealing gasket is fixedly provided on the outer wall of the positioning block, and the sealing gasket is a silicone gasket.
[0012] Preferably, heat insulation pads are fixedly provided at the bottom of the upper injection cavity and inside the lower injection cavity.
[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:
[0014] This invention uses an elastic telescopic rod to push against the top plate to demold the mold. In order to prevent existing molds from lacking an automatic demolding function and avoid the need for manual demolding when using the mold, the elastic telescopic rod pushes against the top plate on the support rod to push the mold out, saving time. In order to prevent slow demolding speed and inconvenience to users, and to reduce the mold cooling time, a water tank is used to cool the mold and prevent sticking, saving a lot of time.
