[0020] Embodiment 1:

[0021] See also Figure 1-5 The utility model provides a technical solution: a three-mold injection molding machine, including a bottom plate 101, a guide plate 102 is fixedly connected to the upper end surface of the bottom plate 101, and the guide plate 102 is slidably connected to a left side plate 103 and a right side plate 106, and two front-to-back symmetrical guide rods 112 are slidably connected between the left side plate 103 and the right side plate 106, and the left and right end surfaces of the guide rod 112 are respectively fixedly connected to a limit plate 113, and the left side plate 103 and the right side plate 106 can be limited by the limit plate 113. The left side plate 103 can be fixedly connected with a first mold 105, and the right side plate 106 can be fixedly connected with a second mold 107. By bringing the first mold 105 and the second mold 107 close to each other, the two molds can be connected and used, thereby realizing injection molding. The upper end surface of the bottom plate 101 is fixedly connected with a fixing plate 108, and the fixing plate 108 can be connected to a third mold 116. By locking the third mold 116 with the first mold 105 and the second mold 107, injection molding of three molds can be realized.

[0022] The fixed plate 108 is fixedly provided with a threaded motor 109, and the threaded motor 109 is powered by two left-right symmetrical threaded shafts 111, and the two threaded shafts 111 are respectively threadedly connected to the left plate 103 or the right plate 106. By starting the threaded motor 109 to drive the threaded shafts 111 to rotate, the left plate 103 and the threaded motor 109 can be driven to move toward or away from the fixed plate 108, thereby realizing the closing and opening of the three molds.

[0023] The left side plate 103 is penetrated and connected with an injection tube 104 which can be connected with the first mold 105 , and injection molding can be performed by connecting the injection tube 104 to the injection tube.

[0024] The fixing plate 108 is threadedly connected to a mounting shaft 114 that passes through the fixing plate 108 . The mounting shaft 114 can be threadedly connected to an auxiliary mounting plate 117 . The auxiliary mounting plate 117 can be fixedly mounted to the third mold 116 .

[0025] A mounting handle 115 is fixedly connected to the front end surface of the mounting shaft 114 for conveniently driving the mounting shaft 114 to rotate.

[0026] The bottom plate 101 is provided with a plurality of through holes for fixing and installing the bottom plate 101 .

[0027] Working principle:

[0028] When in use, the bottom plate 101 is mounted on the plane used for injection molding through the through hole, and then two molds or three molds are selected according to the complexity of the object to be molded;

[0029] If two molds are used, the first mold 105 is installed on the left plate 103, and the second mold 107 is installed on the right plate 106. The installation shaft 114 is rotated by the installation handle 115 so that the installation shaft 114 leaves the fixed plate 108. At this time, the auxiliary installation plate 117 is separated from the fixed plate 108 to prevent the auxiliary installation plate 117 from affecting the mold closing of the first mold 105 and the second mold 107. At this time, the threaded motor 109 is started to drive the threaded shaft 111 to rotate;

[0030] Then, the left plate 103 and the right plate 106 are driven to move toward the fixed plate 108 through the thread and the guide rod 112, and then the first mold 105 and the second mold 107 are driven to approach each other, and then the mold is closed. At this time, the injection tube 104 is connected with the injection tube, and the molten plastic is injected through the injection tube 104 to complete the injection molding work. At this time, the threaded motor 109 is started to drive the threaded shaft 111 to rotate in the opposite direction, and then the left plate 103 and the right plate 106 are driven to reset, and the plastic parts after injection molding can be taken out, and the injection molding work is completed;

[0031] If the plastic parts are more complicated, the auxiliary mounting plate 117 is installed and connected to the fixed plate 108 through the mounting handle 115 and the mounting shaft 114, and the third mold 116 is installed and connected to the auxiliary mounting plate 117, and the threaded motor 109 is started to drive the threaded shaft 111 to rotate, and the left plate 103 and the right plate 106 are driven to move toward the fixed plate 108 through the thread and the guide rod 112, thereby driving the first mold 105 and the second mold 107 to move toward the third mold 116, so as to realize the closing of the first mold 105, the second mold 107 and the third mold 116, so that injection molding can be carried out.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
