Technical Field

[0001] The utility model relates to the field of injection molding of household appliance inner shells, and specifically, to a mold for injection molding of household appliance inner shells. Background Art

[0002] An injection mold is a tool for producing plastic products; it is also a tool for giving plastic products a complete structure and precise dimensions. Injection molding is a processing method used when mass-producing some complex-shaped parts. Specifically, it means injecting the heat-melted plastic into the mold cavity under high pressure by an injection molding machine, and after cooling and solidifying, a formed product is obtained. When the existing mold for injection molding of household appliance inner shells is in use, the upper mold generally descends through a hydraulic rod to make the upper mold and the lower mold close. However, when the upper mold and the lower mold close, the upper mold will impact the lower mold, thereby reducing the service life of the mold for injection molding of household appliance inner shells.

[0026] Through the above technical solution, by setting the mold closing mounting frame 201, the function of facilitating the installation of the lifting hydraulic rod 202 is achieved. The lifting hydraulic rod 202 can drive the upper mold 203 to move, so that the upper mold 203 and the lower module 204 are closed. At the same time, the upper mold 203 will also drive the lifting sliding plates 205 to move, so that the upper mold 203 is stably lifted and lowered by the lifting sliding plates 205 and the sliding rods 206. After that, when the lifting sliding plates 205 contact the buffer sliding plates 207, they are buffered by the buffer damping rods 208 and the buffer return springs 209, so as to achieve the function of improving the service life of the mold. By setting the control switch 5, the function of facilitating the control of the lifting hydraulic rod 202 is achieved.
