[0020] Furthermore, a material receiving drawer 3 is placed below the inner wall of the support frame 1 to facilitate material receiving; further, a cooling assembly 8 is installed on the back of the second die 7 to facilitate cooling of the material; further, a liquid guide groove 17 is opened on the surface of the first die 6 and the mold holes are interconnected through the liquid guide groove 17, and the pouring port on one side of the second die 7 is connected to the pouring assembly through the pouring pipe 10 to facilitate pouring; further, guide plates 16 are fixedly installed on the top and bottom of the first die 6 and are slidably connected to the outside of the second die 7 through the guide plates 16, and a groove 15 is opened at the other end of the inner wall of the support frame 1 corresponding to the guide plates 16, which has a good guiding effect; further, second grooves 13 are opened at the four corners of the opposite surfaces of the first die 6 and the second die 7, and a second spring 14 is installed on the inner wall of the second groove 13, and the first die 6 and the second die 7 are connected through the second spring 14 to facilitate the installation of the second spring 14.

[0021] In this scheme, when in use, a mold for producing disposable plastic cups disclosed by the utility model has a punch 4 and a die placed laterally, and a stripper plate 5 is elastically installed on the punch 4 through an embedded spring, dividing the die into two modules and elastically connected through an embedded spring, so that injection molding can be performed when pressed, and after the material is cooled, the punch 4 is retracted to automatically demould and unload the material without an additional electrical device, and the external power supply controls the extension of the hydraulic component 2 through an external switch to drive the punch 4 to translate to the right until the punch 4 presses the die, at which time the first spring 12 is compressed and retracted into the first groove 11, the punch 4 is tightly attached to the stripper plate 5, the second spring 14 is compressed back into the second groove 13, the first die 6 and the second die 7 are tightly attached, At the same time, the unloading plate 5 is in close contact with the first die 6 to form a closed mold cavity. At this time, after the material liquid is poured through the external pouring component, the plastic cup is quickly cooled by the cooling component 8. After cooling, the hydraulic component 2 is controlled to shorten and retract the punch 4 and the unloading plate 5, so that the punch 4 and the unloading plate 5 are away from the first die 6 and the second die 7.
