[0018] As Figures 1 to 2 shown, the present invention provides an injection molding machine with convenient operation, which includes a support frame 1 and a base 5 fixed to the bottom of the support frame 1. An operation unit 2 is fixedly installed at the top of the support frame 1. A connecting frame 8 is fixedly installed on the outer surface of the top of the support frame 1 through screws. A limiting seat 9 is fixedly installed on the connecting frame 8. A heating unit 3 is arranged in the limiting seat 9. The bottom of the heating unit 3 is connected to a molding unit 4, and the molding unit 4 is installed on the support frame 1. By setting the connecting frame 8 and the limiting seat 9, it is convenient to limit the heating unit 3, and then it is convenient to use the operation unit 2 for pressing operation, providing stable support for the heating unit 3, and it is also convenient to remove the heating unit 3, facilitating the addition of materials and the cleaning of the heating unit 3.

[0019] As Figure 3 shown, the operation unit 2 includes a connecting rod 201 arranged in the support frame 1. A first connecting piece 202 is hinged on the connecting rod 201. A main rod 203 is hinged in the first connecting piece 202. A fixing piece 208 is fixedly sleeved on the main rod 203. A second connecting piece 204 is hinged at the bottom of the fixing piece 208. A sub-rod 205 is hinged in the second connecting piece 204. One end of the main rod 203 is fixedly connected to a handle 207. By setting the sub-rod 205, with the cooperation of other structures in the operation unit 2, it is realized to drive the sub-rod 205 to move downward in the housing 301, so that the melted material is perfectly extruded. The circular ring groove 206 is used to facilitate the escape of gas in the melted material to the cavity formed by the circular ring groove 206 and the inner wall of the housing 301 during the extrusion process, ensuring the perfect molding of the model.

[0020] As Figure 4As shown, the heating unit 3 includes a shell 301, a heating tube 302 is arranged inside the shell 301, a cover body 304 is threadedly connected to the top of the shell 301, a circular groove is opened on the cover body 304, the auxiliary rod 205 is located in the circular groove, and a discharge valve 303 is arranged at the bottom of the shell 301. By arranging the heating tube 302, it is convenient to heat the material. By using the cover body 304, it is prevented that the material splashes out during the heating process to cause burns to the staff, thereby avoiding pollution of the working environment.

[0021] like Figure 5 As shown, the molding unit 4 includes a support seat 401, the inner surface of the support seat 401 is movably connected to a limit frame 402, a mold 403 is movably sleeved in the limit frame 402, a heat dissipation groove is provided at the bottom of the support seat 401, the limit frame 402 is adapted to the mold 403, the support seat 401 is fixedly mounted on the support frame 1 by screws, and the support seat 401 is provided with a heat dissipation groove at the bottom of the support seat 401 to facilitate heat dissipation of the mold 403, and different sizes of limit frames 402 are provided to facilitate the limiting of molds 403 of various sizes.

[0022] like Figures 1 to 5 As shown, a body 6 and a control knob 7 are provided in the support frame 1, and the control knob 7 is located above the body 6. A circular groove 206 is provided on the auxiliary rod 205, and a shell 301 is movably sleeved on the outer surface of the auxiliary rod 205. The outer surface of the shell 301 is movably connected to the limit seat 9, and the shell 301 is adapted to the limit seat 9.

[0023] Working principle of the present invention: During operation, the staff connects the device to an external power source, removes the heating unit 3 located on the limit seat 9, and then places the initial material into the heating unit 3, opens the heating unit 3 by rotating the cover 304, and then places the heating unit 3 so that the auxiliary rod 205 is located in the heating unit 3, and then connects the heating unit 3 to the body 6 through a wire, and controls the operation through the control knob 7, so that the heating tube 302 starts to work, and then heats and melts the material. After a certain time, the staff holds the handle 207 and presses it downward, and under the action of the first connecting member 202 and the second connecting member 204, the connecting rod 205 is connected. 01 is connected to the support frame 1 to provide a fulcrum, so that the auxiliary rod 205 moves downward. At this time, the discharge valve 303 is opened, and the melted material reaches the inside of the mold 403 through the outlet. The annular groove 206 allows the auxiliary rod 205 to squeeze the melted material downward, and the bubbles therein escape to the annular groove 206 through the inner wall of the shell 301, thereby avoiding incomplete model formation and the occurrence of bubble holes, so that the injection molding operation can be completed smoothly. After the injection molding operation is completed for a period of time, the handle 207 is pulled up to disengage the auxiliary rod 205 from the heating unit 3, and then the heating unit 3 is removed from the limit seat 9, and then the heating unit 3 is cleaned, which is easy to operate.
