Background Art

[0002] Injection molding machine is also called injection molding machine or injection machine. It is the main molding equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastics or thermosetting plastics. It is divided into vertical, horizontal and all-electric types. The injection molding machine can heat the plastic and apply high pressure to the molten plastic to make it ejected and fill the mold cavity.

[0023] Referring to Figures 1 to 4 , an auxiliary structure for fixing an energy-saving heating coil of an injection molding machine according to an embodiment of the present utility model includes a fixed protective shell 1. A press-type buckle device 11 is fixedly connected to the front surface of the fixed protective shell 1. The press-type buckle device 11 includes an upper fixing block 1101, a lower fixing block 1102, a buckle head 1103, a fixing plate 1104, a buckle strip 1105, a lock hole 1106, a thin rod 1107, a short rod 1108, a screw 1109, and a buckle base 1110. The circumferential surface of the short rod 1108 is rotatably connected to the inner surface of the upper fixing block 1101. The circumferential surfaces at the left and right ends of the short rod 1108 are rotatably connected to the inner surface of the fixing plate 1104. The right surface of the fixing plate 1104 is fixedly connected to the left surface of the buckle head 1103. The inner surface of the buckle head 1103 is movably connected to the circumferential surface of the upper fixing block 1101. The lock hole 1106 penetrates through the inner surface of the buckle head 1103 and is fixedly connected to the right surface of the upper fixing block 1101. The circumferential surfaces at the left and right ends of the thin rod 1107 are fixedly connected to the inner surface of the fixing plate 1104. The circumferential surfaces at the left and right ends of the thin rod 1107 are fixedly connected to the inner surface of the buckle strip 1105. The upper surface of the buckle strip 1105 is movably connected to the lower surface of the buckle base 1110. The circumferential surface of the screw 1109 penetrates through the buckle base 1110 and is threadedly connected to the inner surface of the lower fixing block 1102. A lock can be installed after the lock hole 1106 is pressed down by the buckle head 1103.

[0024] The inner surface of the fixed protective shell 1 is fixedly connected with an annular mounting seat 12. The inner surface of the annular mounting seat 12 is provided with a heating pipe 8. The annular surface of the heating pipe 8 penetrates through the annular mounting seat 12 and is movably connected to the inner surface of the fixed protective shell 1. A jack is arranged in the left inner cavity of the fixed protective shell 1, and a groove is arranged in the right inner cavity of the fixed protective shell 1. Such a setting can fix the heating pipe 8 in the inner cavity of the fixed protective shell 1.

[0025] The upper and lower surfaces at the left end of the fixed protective shell 1 are fixedly connected with a third rotating shaft 5 and a fourth rotating shaft 6. The other end of the third rotating shaft 5 is fixedly connected with a guard plate 7, and the other end of the fourth rotating shaft 6 is fixedly connected with a guard plate 7. The right surface of the guard plate 7 is movably connected to the left surface of the fixed protective shell 1. The rear surface of the fixed protective shell 1 is fixedly connected with a first rotating shaft 2 and a second rotating shaft 3. The upper and lower surfaces of the fixed protective shell 1 are fixedly connected with a first power-on plate 4, a second power-on plate 9 and a third power-on plate 10. The upper and lower joints of the guard plate 7 are of a tenon structure, which is easy to install and not easy to break free. A soft pad can be installed at the contact between the guard plate 7 and the injection molding machine to increase the friction force so that the auxiliary structure will not move during the production process.

[0026] Working principle: Insert the heating pipe 8 through the empty slot on the left side of the fixed protective shell 1, penetrate through the annular mounting seat 12 and then abut against the bottom slot on the right side of the fixed protective shell 1. After all are installed in sequence, then merge the guard plate 7 through the third rotating shaft 5 and the fourth rotating shaft 6 on the upper and lower surfaces of the fixed protective shell 1. The guard plate 7 is divided into upper and lower sections, and the joint is of a tenon structure. Then fix the fixed protective shell 1 on the pipeline of the injection molding machine through the first rotating shaft 2 and the second rotating shaft 3, and use the push-button buckle device 11 to fix it. The lower end of the buckle strip 1105 hangs on the inner surface of the buckle base 1110, and then press the buckle head 1103 inward, so that the buckle head 1103 and the fixing plate 1104 drive the buckle strip 1105 to stretch upward until the buckle head 1103 is pressed down to the left surface of the fixing plate 1104 and is in full contact with the upper fixing block 1101. At this time, the buckle strip 1105 and the buckle base 1110 will be in tight contact. After the upper and lower parts of the fixed protective shell 1 are tightly fitted, use a lock to pass through the lock hole 1106 to lock it, so that the push-button buckle device 11 will not break free and be released during use. Finally, connect the wires to the protruding parts of the first power-on plate 4, the second power-on plate 9 and the third power-on plate 10, and then start the machine. The heating pipe 8 starts to heat and work. Such a structural setting is convenient for installing, later disassembling the auxiliary structure and replacing the heating pipe 8, so that the installation of the heating pipe 8 is not easy to damage its service life.
