[0016] The present invention provides an injection molding machine with a clamping function. It has the following beneficial effects:

[0017] (1) The injection molding machine with a clamping function starts the driving motor, and the output end of the driving motor moves to drive the clamping plate to move toward the mold. When the clamping plate moves, it contacts the surface of the mold, so that the mold is clamped by the clamping plate to prevent the mold from shifting or offsetting during the injection molding process, resulting in inaccurate docking between the injection port and the mold port, and wasting production resources. The rotation of the rotating rod drives the driving plate to rotate, and the rotation of the driving plate drives the baffle plate to rotate. By using the baffle plate, the mold and the clamping plate are effectively protected after the clamping is completed, reducing the possibility of operators accidentally approaching or contacting the mold, and reducing potential injuries and safety risks.

[0018] (2) The injection molding machine with a clamping function rotates the output end of the rotating motor to drive the rotating rod to rotate, and the rotating rod drives the stirring rod to rotate. The plastic particles inside the injection shell are stirred by the rotation of the stirring rod. The stirring helps to transfer heat evenly to the plastic particles, ensuring that they are evenly melted, thereby improving production efficiency. When the lifting plate moves, it is supported by the semicircular plate, so that the lifting plate moves upward. The upward movement of the lifting plate drives the pushing plate to move upward. By reciprocating the pushing plate up and down, precipitation can be effectively reduced, and the uniformity of mixing can be maintained. At the same time, it can help maintain a uniform temperature distribution and improve melting efficiency.

[0019] (3) In the injection molding machine with a clamping function, when the T-block moves to the specified position, the T-block is separated from the limit groove on the pull plate, so that the movement limit of the pull plate by the T-block is released, preventing the operator from accidentally touching and opening the feed port, which can reduce the risk of shutdown caused by accidental touch and improve the safety during work. The rectangular plate resets and drives the triangular plate to reset. When the triangular plate resets, the vertical surface of the triangular plate drives the plastic particles to move toward the injection shell to prevent blockage inside the feed pipe. Blockage usually requires shutdown for cleaning, which increases production costs, thereby reducing maintenance and repair costs. BRIEF DESCRIPTION OF THE DRAWINGS

The movement of the rotating rod 34 drives the L block 35 to move toward the mold. When the L block 35 moves, it contacts the surface of the workpiece, so that when the rotating rod 34 continues to move, the L block 35 rotates due to the resistance of the mold. A driving plate 36 is fixedly installed on the end of the rotating rod 34 away from the clamping plate 33, and a baffle 37 is slidably installed on the surface of the driving plate 36. A hole groove is opened on the side of the clamping plate 33 away from the driving motor 32, and a spring piece 38 is fixedly installed on the surface of the hole groove. The mold is clamped by the clamping plate 33 to ensure that the mold does not move during the injection molding process, thereby improving the quality of the injection molded product.

[0031] An arc surface is formed on one end of the L block 35 away from the rotating rod 34, and the top of the L block 35 contacts the surface of the hole groove. An elastic protrusion is provided at the bottom of the L block 35. Vibration is generated by intermittent contact between the spring piece 38 and the elastic protrusion to prevent the rotating rod 34 from getting stuck during rotation, thereby improving working stability.

[0032] A spiral spring No. 1 is arranged between the rotating rod 34 and the clamping plate 33, and a spring No. 1 is arranged between the baffle 37 and the driving plate 36. When the baffle 37 moves, the spring No. 1 is squeezed and deformed. A semicircular groove is opened on the top of the baffle 37.

While the rotating rod 34 rotates, the rotating rod 34 drives the driving plate 36 to rotate, and the driving plate 36 drives the baffle 37 to rotate. When the baffle 37 rotates, it contacts the surface of the machine table 1, so that the baffle 37 stops rotating due to the resistance of the machine table 1, and the clamping plate 33 continues to move and contacts the mold surface, so that the mold is clamped by the clamping plate 33. The baffle 37 protects the injection molding area to prevent injuries to the operator when an emergency device occurs.

A pushing plate 46 is fixedly installed on the surface of the lifting plate 45. The stirring rod 43 rotates to drive the lifting plate 45 to move. When the lifting plate 45 moves, the arc surface 2 at the bottom of the lifting plate 45 contacts the top of the semicircular plate 44. When the lifting plate 45 moves, it is supported by the semicircular plate 44, so that the lifting plate 45 moves upward. The upward movement of the lifting plate 45 drives the pushing plate 46 to move upward. A linkage plate 47 is fixedly installed on the surface of the rotating rod 42. The lifting plate 45 reciprocates up and down, which drives the pushing plate 46 to reciprocate up and down, so that the plastic particles inside the injection molded shell 21 are pushed up and down, thereby improving the stirring effect.

[0036] The bottom of the lifting plate 45 is provided with an arc surface 2, and the end of the linkage plate 47 away from the rotating rod 42 is provided with an arc surface 3. A spring 2 is arranged between the lifting plate 45 and the stirring rod 43.

[0037] The feeding device includes a feeding pipe 51, a pulling plate 52 and a feeding port 53. The pulling plate 52 is manually pulled and moved downward by the pulling force, so that the top of the pulling plate 52 is separated from the top of the inner wall of the feeding pipe 51, so that the feeding port 53 and the feeding pipe 51 are restored to be connected. The feeding pipe 51 is fixedly penetrated through the inner and outer walls of the injection molding shell 21, and the pulling plate 52 slides through the bottom of the feeding pipe 51. The feeding port 53 is fixedly installed at one end of the feeding pipe 51 away from the injection molding shell 21.

[0038] A limiting groove is provided on one side of the pull plate 52 close to the feed pipe 51, a T-shaped block 54 is slidably installed at the bottom of the feed pipe 51, a short plate 55 is slidably installed at the bottom of the inner wall of the feed pipe 51, and a rectangular plate 56 is fixedly installed on the surface of the short plate 55. The short plate 55 moves toward the feed pipe 51 under the thrust, and the movement of the short plate 55 causes the spring 5 to deform. At the same time, the movement of the short plate 55 drives the rectangular plate 56 to move toward the feed pipe 51, and a triangular plate 57 is fixedly installed on the top of the rectangular plate 56. Through the reciprocating movement of the triangular plate 57, the plastic particles inside the feed pipe 51 are pushed back and forth by the triangular plate 57 to prevent the inside of the feed pipe 51 from being blocked.

[0039] A handle is fixedly installed at the bottom of the pull plate 52. The operator manually pulls the handle to move the handle and drive the pull plate 52 to move.

[0040] A spring three is arranged between the pull plate 52 and the feed pipe 51. When the pull plate 52 moves, the spring three is squeezed by the pull plate 52 and deformed. A spring four is arranged between the T-shaped block 54 and the feed pipe 51, and a spring five is arranged between the short plate 55 and the feed pipe 51. Through the elasticity of the spring three itself, the squeezed spring three is reset to drive the pull plate 52 to move to the initial position to prepare for the next work.

[0041] When the present embodiment is working, plastic particles are manually placed into the injection molding shell 21, and the plastic particles fall onto the top of the heating tube 22. The heating tube 22 is started to melt, and the rotating motor 41 is started. The output end of the rotating motor 41 rotates to drive the rotating rod 42 to rotate, and the rotating rod 42 rotates to drive the linkage plate 47 to move. At the same time, the rotating rod 42 rotates to drive the stirring rod 43 to rotate. When the stirring rod 43 rotates, it contacts the surface of the plastic particles, so that the plastic particles are moved by the thrust. The stirring rod 43 is used to stir the plastic particles, so as to prevent the plastic particles from staying on the top of the heating tube 22 for a long time, thereby improving the melting effect. When the stirring rod 43 rotates, The stirring rod 43 rotates to drive the lifting plate 45 to move. When the lifting plate 45 moves, the arc surface 2 at the bottom of the lifting plate 45 contacts the top of the semicircular plate 44. When the lifting plate 45 moves, it is supported by the semicircular plate 44, so that the lifting plate 45 moves upward. The upward movement of the lifting plate 45 drives the push plate 46 to move upward. The stirring rod 43 continues to rotate to drive the lifting plate 45 to move, so that the arc surface 2 of the lifting plate 45 is separated from the top of the semicircular plate 44. The lifting plate 45 reciprocates up and down, driving the push plate 46 to reciprocate up and down, so that the plastic particles inside the injection shell 21 are pushed up and down, thereby improving the stirring effect.

[0042] When pouring plastic particles, the T-shaped block 54 is manually pushed to move the T-shaped block 54 in the direction away from the pull plate 52. When the T-shaped block 54 moves to the specified position, the end of the T-shaped block 54 close to the pull plate 52 is separated from the limit groove on the pull plate 52, so that the movement limit of the pull plate 52 by the T-shaped block 54 is released. Then the pull plate 52 is manually pulled, and the pull plate 52 moves downward under the tension, so that the top of the pull plate 52 is separated from the top of the inner wall of the feed pipe 51, so that the feed port 53 and the feed pipe 51 are restored to be connected. The feeding can only be carried out after the limit is released, which prevents the operator from making wrong operations under incorrect circumstances and improves the safety during work. When the linkage plate 47 rotates, the arc surface three of the linkage plate 47 contacts the arc surface four of the short plate 55, so that the short plate 55 is affected. The thrust moves in the direction of the feed pipe 51, and the short plate 55 moves to deform the spring five. At the same time, the movement of the short plate 55 drives the rectangular plate 56 to move in the direction of the feed pipe 51, and the movement of the rectangular plate 56 drives the triangular plate 57 to move in the direction of the feed pipe 51. After the linkage plate 47 continues to rotate and separates from the short plate 55, the spring five accumulates energy and resets to drive the short plate 55 to move and reset. The movement and reset of the short plate 55 drives the rectangular plate 56 to reset in the direction away from the feed pipe 51. The reset of the rectangular plate 56 drives the triangular plate 57 to reset in the direction away from the feed pipe 51. When the triangular plate 57 is reset, the vertical side of the triangular plate 57 drives the plastic particles inside the feed pipe 51 to move in the direction of the injection molding shell 21. The reciprocating movement of the triangular plate 57 prevents the inside of the feed pipe 51 from being blocked.
