[0019] The following is combined with Figure 1-5 This application is described in further detail.

[0020] The present application embodiment discloses a foam plastic molding machine. Figure 1-3 , including a processing seat 1, one side of the upper end of the processing seat 1 is connected to a placement seat 2, both sides of the placement seat 2 are connected to auxiliary reinforcement components 3, the upper end of the processing seat 1 is connected to an extrusion component 4, the extrusion component 4 is electrically connected through an external power supply, the extrusion component 4 drives the support plate 5 to move downward or upward, and then the forming seat 6 moves to the upper end of the placement seat 2 to form the material, the outside of the extrusion component 4 is slidably connected to the support plate 5, the lower end of the support plate 5 is connected to the forming seat 6, the upper end of the forming seat 6 is provided with through openings all around, the diameter of the through openings is larger than the diameter of the fixed plate 7, the fixed plate 7 moves to the inside of the through openings, if the through openings are not provided, the fixed plate 7 will move downwards and will abut against the upper end of the processing seat 1 and cannot move downwards, so the through openings are provided for convenience The fixing plate 7 moves, and the fixing plates 7 are symmetrically connected to the two sides of the outside of the forming seat 6. One end of the fixing plate 7 is connected to the limiting block 9, and one side of the fixing plate 7 is connected to a rack 8. The rack 8 meshes with the tooth groove 35, and the rack 8 moves with the fixing plate 7 and contacts with the tooth groove 35. When the fixing wheel 34 is fixed, the rack 8 is fixed accordingly. The auxiliary reinforcement component 3 includes a mounting seat 31 installed on both sides of the placement seat 2. A limiting groove 32 is provided at one end of the mounting seat 31, and the limiting groove 32 corresponds to the limiting block 9. The fixing plate 7 drives the limiting block 9 to move downward, and the limiting block 9 moves to the inside of the limiting groove 32 to play a positioning role, thereby ensuring that the fixing plate 7 moves vertically downward to avoid the fixing plate 7 from shifting when moving downward, thereby affecting use.

[0021] Reference Figure 4-5A rotating shaft 33 is rotatably connected to the inner side of the mounting seat 31, and a fixed wheel 34 is sleeved on the outer side of the rotating shaft 33. A tooth groove 35 is opened on the outer side of the fixed wheel 34. A pull rope 36 is connected to one end of the mounting seat 31, and one end of the pull rope 36 is connected to a winding wheel 37. One end of the winding wheel 37 is connected to a rotating block 38. The rotating block 38 is convenient for rotating the winding wheel 37. It is inconvenient to directly rotate the winding wheel 37. It is more labor-saving to add a rotating block 38. A guide wheel 39 is slidably connected to one side of the outer side of the pull rope 36. The guide wheel 39 guides the pull rope 36 to change the pulling direction of the pull rope 36, and then pull the pull rope 36. When the rope 36 is pulled, the movable plate 310 is driven to move, and the guide wheel 39 protects the pull rope 36 to prevent the pull rope 36 from directly contacting the mounting seat 31 and being worn out after long-term use, thereby extending the service life of the pull rope 36. One end of the guide wheel 39 is connected to one side of the mounting seat 31, and the other end of the pull rope 36 is connected to the movable plate 310. One end of the movable plate 310 is connected to the plug-in block 311. The lower end of the plug-in block 311 is arranged in an inclined structure. The plug-in block 311 is plugged into the tooth groove 35. When the fixed plate 7 drives the rack 8 to contact the fixed wheel 34, the fixed plate 7 moves downward to drive the fixed wheel 34 to rotate, and the fixed wheel 34 rotates clockwise. The tooth groove 35 contacts the inclined side of the plug-in block 311 during the rotation process. Therefore, when the fixed plate 7 moves downward, the plug-in plate will not affect the use of the fixed wheel 34. When the fixed plate 7 moves upward, the tooth groove 35 and one side of the plug-in plate are in contact. At this time, the fixed wheel 34 and the plug-in plate are locked, which has a fixing effect on the placement seat 2 and the forming seat 6, ensuring a better sealing effect between the forming seat 6 and the placement seat 2 during material processing. When the placement seat 2 and the plug-in block 311 of the forming seat 6 are located inside the tooth groove 35, both sides of one end of the moving plate 310 are connected to round rods 312, and one end of the round rod 312 is connected to a limiting plate 313 The limiting plate 313 limits the round rod 312 to prevent the round rod 312 from being separated from the support plate 314. A support plate 314 is sleeved on one side of the outer side of the round rod 312. One end of the support plate 314 is connected to one side of the mounting seat 31. A spring 315 is sleeved on one side of the outer side of the round rod 312. The spring 315 has elastic potential energy. When the fixed wheel 34 rotates clockwise, the elastic potential energy of the spring 315 drives the plug-in plate to reciprocate, so that the movable plate 310 is automatically plugged into the tooth groove 35. One end of the spring 315 is connected to one side of the support plate 314, and the other end of the spring 315 is connected to one side of the movable plate 310.

[0022] The implementation principle of the foam plastic molding machine of the embodiment of the present application is as follows: when in use, the extrusion assembly 4 drives the support plate 5 to move downward, the support plate 5 drives the molding seat 6 and the fixed plate 7 to move downward at the same time, the fixed plate 7 moves to the inside of the mounting seat 31, the limit block 9 moves to the inside of the limit groove 32 to ensure that the fixed plate 7 will not deviate, the fixed plate 7 drives the rack 8 to move, the rack 8 is engaged with the tooth groove 35, and as the fixed plate 7 moves downward, it drives the fixed wheel 34 to rotate. When the placement seat 2 and the molding seat 6 are fitted, the fixed plate 7 no longer moves downward. At this time, the plug-in plate fixes the fixed wheel 34, thereby The support plate 5 moves upward by rotating the rotating block 38, and the rotating block 38 drives the winding wheel 37 to rotate, and the winding wheel 37 drives the pull rope 36 to move, so that the pull rope 36 is wound around the outside of the winding wheel 37, and the movement of the pull rope 36 drives the moving plate 310 to move, so that the moving plate 310 drives the plug-in plate to move from the inside of the tooth groove 35 to the outside, so as to facilitate the fixed plate 7 to move to the original position.
