DETAILED DESCRIPTION

[0016] In order to make the purpose and technical solution of the present invention clearly and completely described, and the advantages more clearly understood, the embodiments of the present invention are further described in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, rather than all of the embodiments, and are only used to explain the embodiments of the present invention, and are not used to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] For example, see Figure 1 - Fig.10The present invention provides a technical solution for an integrated impeller high-efficiency injection mold: the integrated impeller high-efficiency injection mold comprises: a fixed mold 1 and a movable mold 2, the outer wall of the bottom of the fixed mold 1 is in active contact with the outer wall of the top of the movable mold 2, a cavity is opened inside the fixed mold 1, and the outer walls on both sides of the fixed mold 1 are provided with adjustment mechanisms, the adjustment mechanisms include a motor 3, the outer wall at the bottom of the motor 3 is fixedly connected with a bottom plate, the outer walls on the opposite sides of the two bottom plates are fixedly connected with the outer walls on both sides of the fixed mold 1, the output ends of the two motors 3 pass through the interior of the cavity and are fixedly connected with a bevel gear 1 32, the inner walls of the two cavities are rotatably connected with a bidirectional screw rod 31, the middle position of the outer walls of the two bidirectional screw rods 31 is fixedly connected with a bevel gear 2 33, and the outer wall of the bevel gear 2 33 is meshed with the outer wall of the bevel gear 1 32.

[0018] The movement of the motor 3 can drive the adjustment mechanism to move, so that the fixed shell 42 can automatically fix the fixed mold 1 and the movable mold 2 together, avoiding the need for the operator to manually adjust the position of the fixed shell 42, thereby reducing the operator's workload accordingly, and further improving the efficiency of adjusting the fixed shell 42 through mechanical drive.

[0019] Embodiment 2: On the basis of embodiment 1, the outer wall of the bidirectional screw rod 31 is threadedly connected with a moving rod 4, the outer walls of the two moving rods 4 are fixedly connected with push rods 3 41, the outer walls on the opposite sides of the two push rods 41 are fixedly connected with a fixed shell 42, the outer walls at both ends of the fixed mold 1 are provided with a fixing groove 34, the interior of the fixing groove 34 is movably connected with the outer wall of the fixed shell 42, the shape of the fixed shell 42 is L-shaped, the outer walls at both ends of the movable mold 2 are provided with L-shaped fixing grooves 35, the outer wall of the fixed shell 42 is movably connected with the interior of the L-shaped fixing groove 35.

[0020] By increasing the stability of the connection between the fixed mold 1 and the movable mold 2, the unstable connection between the fixed mold 1 and the movable mold 2 is avoided. During the injection molding process, the mold will find it difficult to maintain its proper fixed state, resulting in quality problems and defects in the plastic product. Correspondingly, the stability between the fixed mold 1 and the movable mold 2 is increased, and defects in product quality due to the unstable connection between the fixed mold 1 and the movable mold 2 are avoided, further increasing the perfection of the product.

[0021] Embodiment three, on the basis of embodiment two, a limiting slide groove is opened at the lower part inside the cavity, the interior of the limiting slide groove is slidably connected to the lower part of the outer wall of the moving rod 4, an installation groove 63 is opened inside the limiting slide groove, a limiting groove 62 is opened on the outer wall at the bottom of the moving rod 4, a return spring three 61 is fixedly connected to the lower part inside the limiting groove 62, the outer wall at the top of the return spring three 61 is fixedly connected to the limiting block 6, the outer wall of the limiting block 6 is movably plugged into the interior of the limiting groove 62, and the two sides of the top of the limiting block 6 are arc-shaped.

[0022] By inserting the limit block 6 into the limit groove 62, the moving rod 4 can be limited. At this time, the movement of the motor 3 can be stopped, which prevents the moving rod 4 from driving the fixed shell 42 to fix the fixed mold 1 too tightly when there is no limit. Correspondingly, it prevents the fixed shell 42 from applying too much clamping force to the fixed mold 1 to damage the fixed mold 1. The limit block 6 and the moving rod 4 are used to limit the movement, so that the stability of the moving rod 4 after stopping is further increased.

[0023] Embodiment 4, on the basis of embodiment 3, a slot hole is opened inside the moving rod 1 4 near the upper limit slot 62, a return spring 2 55 is fixedly connected to the upper part inside the slot hole, a pressure rod 53 is fixedly connected to the outer wall at the bottom of the return spring 2 55, a push rod 2 54 is fixedly connected to the outer wall at the bottom of the pressure rod 53, a pressure plate 56 is fixedly connected to the outer wall at the bottom of the push rod 2 54, the outer wall at the bottom of the push rod 2 54 is fixedly connected to the pressure plate 56, the outer wall at the bottom of the pressure plate 56 is in active contact with the outer wall at the top of the limit block 6, the outer wall of the pressure rod 53 is slidably connected to the inside of the slot hole, the outer walls on both sides of the fixed mold 1 are opened with movable slots, and the inner part of the movable slot is slidably connected to the push rod 1 5. The outer wall of the bottom of the push rod 5 is fixedly connected with a lower pressure shell 57, and the interior of the movable groove is fixedly connected with a return spring 52. The outer wall of the top of the return spring 52 is fixedly connected with the outer wall of the bottom of the push rod 5. The outer wall of the bottom of the lower pressure shell 57 is movably plugged with the outer wall of the pressure rod 53. A receiving groove 7 is opened on the outer wall of one side of the movable groove. The interior of the receiving groove 7 is fixedly connected with a rotating rod 72. The outer wall of the rotating rod 72 is rotatably connected with a moving rod 2 71, so that the outer wall of the moving rod 2 71 is movably contacted with the interior of the receiving groove 7, and the outer wall of the bottom of the moving rod 2 71 is movably contacted with the outer wall of the top of the push rod 5.

[0024] The operator presses the push rod 1 5 to the bottom of the moving groove, and then rotates the moving rod 2 71 out from the storage groove 7 and fixes it on the top of the push rod 1 5, which avoids the need for the operator to keep pressing the push rod 1 5 with his hands when the push rod 1 5 starts to work downward, and correspondingly frees the operator's hands to operate other equipment; By releasing the limit between the limit block 6 and the moving rod 4, the moving rod 4 can be moved under the movement of the motor 3, avoiding the limit block 6 fixed inside the limit groove 62 to affect the movement of the moving rod 4. Correspondingly, through the movement of the pressure rod 53 under force, the limit block 6 can quickly leave the inside of the limit groove 62, thereby releasing the limit on the moving rod 4.

[0025] Embodiment 5, on the basis of embodiment 4, a push groove 81 is provided on the outer wall at the top of the movable mold 2, a lower push plate 82 is slidably connected inside the push groove 81, a square groove 8 is movably inserted into the outer wall of the lower push plate 82, and the outer wall at the top of the lower push plate 82 is fixedly connected to the outer wall at the bottom of the push rod three 41.

[0026] By making the bottom of the square groove 8 an inclined surface, when the square groove 8 moves inside the pushing groove 81, a thrust can be generated on the pushing groove 81, thereby pre-separating the fixed mold 1 and the movable mold 2. The pre-separation action can reduce the friction and adhesion between the fixed mold 1 and the movable mold 2, making the force required for the mold to be fully opened smaller, thereby reducing the resistance and energy consumption of the mold opening, making the mold opening process faster and smoother.

[0027] Embodiment 6, on the basis of embodiment 2, the interior of the fixed shell 42 is movably connected with a mounting plate 422, the outer wall on one side of the mounting plate 422 is fixedly connected with a rubber pad 423, the outer wall on the other side of the mounting plate 422 is fixedly connected with a mounting seat, the interior of the mounting seat is rotatably connected with a threaded rod 421, and the outer wall of the threaded rod 421 is threadedly connected to the interior of the fixed shell 42.

[0028] By adjusting the clamping force of the fixed shell 42 on the fixed mold 1 and the movable mold 2, the situation of over-tightening or under-clamping can be avoided. Over-tightening can easily damage the fixed mold 1 and the movable mold 2, while under-clamping cannot effectively fix the fixed mold 1 and the movable mold 2 together. The corresponding operator can accurately adjust the clamping force through slight rotation movements according to actual needs, neither too tight nor too loose, thereby further realizing precise control of the clamping force.

[0029] In actual use, when working, first, after the fixed mold 1 and the movable mold 2 are closed, the operator can start the motor 3, and then through the rotation of the motor 3, the bevel gear 1 32 can drive the bevel gear 2 33 to move accordingly, and then through the fixed connection between the bevel gear 2 33 and the bidirectional screw rod 31, the bidirectional screw rod 31 can be rotated while the bevel gear 2 33 rotates. Through the movement of the motor 3, the adjustment mechanism can be driven to move, so that the fixed shell 42 can automatically fix the fixed mold 1 and the movable mold 2 together, avoiding the need for the operator to manually adjust the position of the fixed shell 42, correspondingly reducing the workload of the operator, and further improving the efficiency of adjusting the fixed shell 42 through mechanical drive.

[0030] By rotating the two-way screw rod 31, the two-way screw rod 31 can drive the moving rod 4 to slide inside the limiting slide groove. By cooperating with the moving rod 4 and the limiting slide groove, the movement of the moving rod 4 on the two-way screw rod 31 can be limited, thereby preventing the moving rod 4 from rotating with the rotation of the two-way screw rod 31, and correspondingly preventing the moving rod 4 from rotating with the two-way screw rod 31 as the axis, so that the moving rod 4 can move left and right on the two-way screw rod 31.

[0031] By moving the moving rod 1 4, the push rod 3 41 can drive the fixed shell 42 to enter the inside of the fixed groove 1 34 and the L-shaped fixed groove 35 at the same time, so that the protrusion on one side of the fixed shell 42 is inserted into the groove on one side of the L-shaped fixed groove 35, and the fixed mold 1 can be fixed on the movable mold 2. Since the fixed shell 42 and the L-shaped fixed groove 35 are L-shaped, when the fixed shell 42 is inserted into the inside of the L-shaped fixed groove 35, the impact force during injection molding into the mold can be prevented from causing the fixed mold 1 to move on the movable mold 2, which correspondingly increases the stability of the connection between the fixed mold 1 and the movable mold 2. When the bidirectional screw rod 31 stops moving, the bidirectional screw rod 31 and the movable mold 2 can be connected. The threaded connection between the movable rod 4 utilizes the cooperation of the inner and outer wall threads, so that the movable rod 4 can drive the fixed shell 42 to stop in place, avoiding the phenomenon that the mold will cause the fixed mold 1 to move left and right on the movable mold 2 during the injection process, and correspondingly increasing the stability of the connection between the fixed mold 1 and the movable mold 2, avoiding the unstable connection between the fixed mold 1 and the movable mold 2, and avoiding the mold will be difficult to maintain its proper fixed state during the injection process, resulting in quality problems and defects in the plastic product, and correspondingly increasing the stability between the fixed mold 1 and the movable mold 2, avoiding defects in product quality due to the unstable connection between the fixed mold 1 and the movable mold 2, and further increasing the perfection of the product.

[0032] By moving the moving rod 4 to the position of the limit block 6, the limit block 6 can be squeezed through the arcs on both sides of the limit block 6, so that the limit block 6 enters the interior of the installation groove 63. When the limit block 6 is aligned with the limit groove 62, the limit block 6 can be pushed back to its original position under the action of the return spring 3 61 and inserted into the interior of the limit groove 62 to limit the moving rod 4. At this time, the movement of the motor 3 can be stopped, avoiding the moving rod 4 from driving the fixed shell 42 to fix the fixed mold 1 too tightly when there is no limit, and correspondingly preventing the fixed shell 42 from applying too much clamping force to the fixed mold 1 to damage the fixed mold 1. The limit of the limit block 6 and the moving rod 4 further increases the stability of the moving rod 4 after stopping.

[0033] When the operator rotates the threaded rod 421 and then pushes or pulls back the mounting plate 422 through the threaded rod 421, the clamping force of the fixed shell 42 on the fixed mold 1 and the movable mold 2 can be adjusted, thereby avoiding the situation where the clamping is too tight or not in place. If the clamping is too tight, it is easy to damage the fixed mold 1 and the movable mold 2, and if the clamping is not in place, the fixed mold 1 and the movable mold 2 cannot be effectively fixed together. The corresponding operator can accurately adjust the clamping force through slight rotation movements according to actual needs, neither too tight nor too loose, thereby further realizing precise control of the clamping force.

[0034] When the mold needs to be removed after the injection molding is completed, the operator first presses the push rod 1 5 to the bottom of the movable groove, and then rotates the movable rod 2 71 out from the inside of the storage groove 7 and fixes it on the top of the push rod 1 5, avoiding the operator's hand pressing the push rod 1 5 all the time when it starts to work downward, and correspondingly freeing the operator's hands to operate other equipment.

[0035] When the push rod 5 moves downward, the lower pressure shell 57 can be driven to move downward, so that the lower pressure shell 57 pushes the pressure rod 53, and the pressure rod 53 can drive the push rod 2 54 and the pressure plate 56 to move downward. The pressure generated by the downward movement of the pressure plate 56 can then be used to push the limit block 6 into the interior of the installation groove 63, thereby releasing the limit between the limit block 6 and the moving rod 4. At this time, under the movement of the motor 3, the moving rod 4 can be moved, avoiding the limit block 6 being fixed in the interior of the limit groove 62 to affect the movement of the moving rod 4. Correspondingly, through the movement of the pressure rod 53 under force, the limit block 6 can quickly leave the interior of the limit groove 62, thereby releasing the limit on the moving rod 4.

[0036] When the push rod 41 slides out into the interior of the cavity, the fixed shell 42 can release the fixation on the fixed mold 1 and the movable mold 2, and drive the square groove 8 to move inside the push groove 81. Since the bottom of the square groove 8 is an inclined surface, the square groove 8 can generate a thrust on the push groove 81 when it moves inside the push groove 81, so that the fixed mold 1 and the movable mold 2 are pre-separated. The pre-separation action can reduce the friction and adhesion between the fixed mold 1 and the movable mold 2, so that the force required for the mold to be fully opened is smaller, thereby reducing the resistance and energy consumption of the mold opening, and making the mold opening process faster and smoother.

[0037] 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.
