[0015] The following is combined with Figure 1-3 This application is described in further detail.
[0016] The present application embodiment discloses a blowout-proof plastic molding machine, referring to Figure 1 and Figure 2, comprising a bottom plate 1, a frame 2 and a protective cover 51, the two ends of the bottom of the frame 2 are respectively welded to the two ends of the top of the bottom plate 1, a lower mold 31 is welded to the middle of the top of the bottom plate 1, and an upper mold 32 is movably engaged inside the lower mold 31. A first lifting assembly 4 for driving the upper mold 32 to rise and fall is provided at the top of the frame 2, which not only supports the upper mold 32, but also enables the upper mold 32 to be inserted into the lower mold 31, and then the upper mold 32 cooperates with the lower mold 31 to mold the high-temperature plastic liquid in the lower mold 31;
[0017] Reference Figure 1 , Figure 2 and Figure 3 The protective cover 51 is located above the upper mold 32. A circular frame 52 is fixedly sleeved on the outer surface of the lower mold 31, and a circular groove is provided on the top of the circular frame 52. Through holes are provided on the two inner side walls of the frame 2. Movable blocks 53 are slidably connected inside the two through holes. The two sides of the two movable blocks 53 are respectively fitted with the two inner side walls of the two through holes. The two movable blocks 53 are welded to the protective cover 51. The two ends of the top of the frame 2 are provided with a second lifting assembly 6 for driving the two movable blocks 53 to rise and fall. After the second lifting assembly 6 drives the two movable blocks 53 to drive a protective cover 51 to rise and fall, the protective cover 51 completely covers the upper mold 32, and the bottom end of the protective cover 51 is tightly engaged in the circular groove opened at the top of the circular frame 52. Then, the first lifting assembly 4 is used to drive the upper mold 32 to rise inside the protective cover 51 to open the mold. During this process, the protective cover 51 and the circular frame 52 cooperate to completely cover the upper mold 32, which can prevent water vapor from spraying everywhere after the mold opening, thereby preventing the staff from being scalded.
[0018] Reference Figure 2 and Figure 3 The first lifting assembly 4 is composed of a connecting piece 41 and a hydraulic cylinder 42. The connecting piece 41 movably passes through the frame 2 and the protective cover 51, and the contact between the connecting piece 41 and the protective cover 51 is tightly fitted to prevent water vapor from spraying out from the contact between the connecting piece 41 and the protective cover 51. The two ends of the bottom of the connecting piece 41 are respectively welded to the two ends of the top of the upper mold 32. The hydraulic cylinder 42 is fixedly installed in the middle of the top of the frame 2. The end of the hydraulic rod of the hydraulic cylinder 42 is welded to the middle of the inner top wall of the connecting piece 41. When the hydraulic rod of the hydraulic cylinder 42 pushes the connecting piece 41 to drive the upper mold 32 to rise and fall, the lower mold 31 and the upper mold 32 can be opened and closed.
[0019] Reference Figure 1 and Figure 2The two second lifting components 6 are each composed of a motor 61 and a threaded rod 62. The two motors 61 are respectively fixedly mounted at the two ends of the top of the frame 2. The power shafts of the two motors 61 rotate and penetrate the frame 2. The two threaded rods 62 respectively thread through the two movable blocks 53. The threads of the two threaded rods 62 are opened in the same direction. One end of the two threaded rods 62 is respectively welded to the power shafts of the two motors 61, and the other ends of the two threaded rods 62 are respectively rotated and inserted in the middle of the inner bottom walls of the two through holes. When the power shafts of the two motors 61 drive the two threaded rods 62 to rotate synchronously, the two threaded rods 62 can drive the two movable blocks 53 to rise and fall during the rotation process, and the two movable blocks 53 can drive the protective cover 51 to rise and fall during the lifting process.
[0020] Reference Figure 1 and Figure 2 A thermometer 7 is fixedly passed through one of the corners at the top of the protective cover 51 , and can be used to monitor the temperature in the closed space formed by the protective cover 51 and the circular frame 52 .
[0021] The implementation principle of the blowout-proof plastic molding machine of the present application embodiment is as follows: when in use, the hydraulic cylinder 42 is started, the hydraulic rod of the hydraulic cylinder 42 drives the connecting member 41 to descend, and the connecting member 41 drives the hydraulic cylinder 42 to descend, so that the upper mold 32 can be inserted into the lower mold 31, and then the upper mold 32 cooperates with the lower mold 31 to mold the high-temperature plastic liquid in the lower mold 31;
[0022] Afterwards, the two motors 61 are started, and the power shafts of the two motors 61 drive the two threaded rods 62 to rotate synchronously. The two threaded rods 62 can drive the two movable blocks 53 to descend during the rotation, and the two movable blocks 53 can drive the protective cover 51 to rise and fall during the descent, so that the bottom end of the protective cover 51 is tightly engaged in the circular groove opened at the top of the circular frame 52. Then, the hydraulic rod of the hydraulic cylinder 42 is used to drive the connecting piece 41 to rise, and the connecting piece 41 drives the hydraulic cylinder 42 to rise, and the connecting piece 41 drives the upper mold 32 to rise inside the protective cover 51 for mold opening. In this process, the protective cover 51 and the circular frame 52 cooperate to completely cover the upper mold 32, which can prevent water vapor after mold opening from spraying everywhere, thereby preventing the staff from being scalded.
