[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] Reference Figure 1 and Figure 2The utility model provides an embodiment: an injection molding machine with a quantitative injection molding function, comprising a support plate 1 and a top shell 4, a shell 3 is placed on the top wall of the support plate 1, a servo motor 5 is fixedly connected to the top wall of the top shell 4, the output end of the servo motor 5 is fixedly connected to a rotating column 6, the middle part of the rotating column 6 is fixedly connected to a horizontal plate 7, a heating rod 9 is fixedly installed on the left side of the bottom wall of the horizontal plate 7, a stirring blade 10 is fixedly connected to the right side of the bottom wall of the horizontal plate 7, a fixing plate 8 is fixedly connected to the bottom wall of the heating rod 9, the right side of the fixing plate 8 is fixedly connected to the left side of the rotating column 6, and the left side of the top wall of the top shell 4 is fixed. A filling indicator light 16 is fixedly installed, a filling valve 17 is connected to the right side of the top wall of the top shell 4, and an injection valve 18 is connected to the front side of the shell 3. A cleaning component is provided on the left side of the horizontal plate 7, and a fixing mechanism 2 is provided on the left and right sides of the top wall of the support plate 1; the cleaning component includes two fixing blocks 11, the bottom wall of the top fixing block 11 is fixedly connected to the left side of the top wall of the horizontal plate 7, and the top wall of the bottom fixing block 11 is fixedly connected to the left side of the bottom wall of the fixing plate 8. The right sides of the two fixing blocks 11 are both threaded with a threaded knob 12, and the left sides of the two threaded knobs 12 are both threaded with a scraper 13;

[0030] Specifically, when the servo motor 5 is started, the rotating column 6 rotates accordingly, thereby driving the horizontal plate 7 and fixed plate 8 to rotate. This rotational motion enables the heating rod 9 and stirring blades 10 to efficiently stir and heat the material inside the housing 3. The heating rod 9 transfers heat energy evenly to the material through infrared radiation, raising the material temperature and enhancing its fluidity. At the same time, the rotational motion of the stirring blades 10 thoroughly stirs the material, effectively preventing localized solidification caused by temperature unevenness during the heating process. This combined heating and stirring action allows the material to maintain optimal fluidity before injection, significantly reducing the risk of solidification during the injection process. Furthermore, the device is equipped with an injection indicator 16 for real-time prompts during the injection process. When the material injection volume reaches a preset value, the injection indicator 16 emits a signal to remind the operator to stop injection, thereby avoiding the problem of material overflow caused by overinjection. This not only ensures the accuracy of the injection molding process but also greatly improves the operating efficiency of the injection molding machine.

[0031] Reference Figure 1 and Figure 3 The fixing mechanism 2 includes two hydraulic rods 201, the bottom walls of the hydraulic rods 201 are fixedly connected to the left and right sides of the top wall of the support plate 1 respectively, the output ends of the two hydraulic rods 201 are fixedly connected to the connecting plate 202, the outer wall of the top shell 4 is fixedly connected to the inner wall of the connecting plate 202, the top wall of the connecting plate 202 is fixedly connected with a plurality of fixing caps 203 at equal intervals, and the bottom walls of the plurality of fixing caps 203 all begin to have a snap-fitting groove 204, and the four corners of the top wall of the support plate 1 are fixedly connected with fixing columns 205, and the top ends of the plurality of fixing columns 205 are respectively snap-fitted with the corresponding snap-fitting grooves 204;

[0032] Specifically, when the hydraulic rod 201 is started, the control connecting plate 202 is displaced so that it is in close contact with the top shell 4. A plurality of fixing caps 203 and corresponding fixing columns 205 are introduced between the outer shell 3 and the top shell 4. These fixing caps 203 and fixing columns 205 are designed with precise snap-fitting to make the connection between the outer shell 3 and the top shell 4 more secure. This design not only improves the stability of the outer shell 3 and the top shell 4, but also reduces the possibility of the device shaking during operation. In actual application, this optimized device structure has shown significant advantages in the injection molding process. This avoids the separation of the injection molding work due to shaking, thereby greatly improving the success rate of injection molding.

[0033] Reference Figure 1 、 Figure 2 and Figure 3 The bottom wall of the top shell 4 is fixedly connected to a sealing ring 21, and the top wall of the outer shell 3 is provided with an annular groove 19, and the bottom of the sealing ring 21 is engaged with the annular groove 19; the front side of the outer shell 3 is fixedly connected to the control switch 14, and the control switch 14 is electrically connected to the servo motor 5 and the hydraulic rod 201 respectively; the front side of the outer shell 3 is provided with a dust cover 15, and the rear side of the dust cover 15 is rotatably connected to the front side of the control switch 14 through a hinge;

[0034] Specifically, the bottom of the sealing ring 21 is engaged with the ring groove 19, so that the sealing between the top shell 4 and the outer shell 3 is improved. The control switch 14 is electrically connected to the servo motor 5 and the hydraulic rod 201 respectively, so that the control switch 14 can complete the opening and closing of the device. The dust cover 15 can prevent dust and protect the control switch 14.

[0035] Reference Figure 1 , the left and right sides of the bottom wall of the support plate 1 are fixedly connected with a support frame 20; the left side of the shell 3 is fixedly installed with an observation window 22;

[0036] Specifically, the two support frames 20 make the device more stable during operation, and the observation window 22 allows the interior of the injection molding machine to be visually observed.

[0037] Working principle: When starting to work, by starting the servo motor 5, the rotating column 6 drives the horizontal plate 7 and the fixed plate 8 to rotate, and then the heating rod 9 and the stirring blade 10 can stir and heat the material inside the shell 3, thereby improving the fluidity of the material, and reducing the solidification of the material due to the decrease in temperature, thereby facilitating the injection molding work of the injection molding machine and improving the working efficiency of the device. The injection indicator light 16 can be used to prompt during injection molding to avoid excessive injection and material overflow, thereby completing the function of quantitative injection, and by starting the two hydraulic rods 201, the top shell 4 can be fixed to the shell 3 through the connecting plate 202, so that a plurality of fixing caps 203 are engaged with the corresponding fixing columns 205, which improves the stability of the shell 3 and the top shell 4, thereby reducing the possibility of shaking when the device is working, thereby avoiding the situation where the injection molding work is detached and causes injection failure.
