[0018] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0019] Reference Figure 1-3As shown, an internal support mold for a can product comprises a control cabinet 1 with a hollow interior, an internal support rotating mold for shrinking the can product, and a power mechanism matched with the internal support rotating mold;

[0020] The internal support type rotary mold comprises a turntable 2 rotatably arranged in the inner wall of the top end of the control cabinet 1, an assembly seat 3 which is installed on the top end of the turntable 2 by bolts in an I-shape, and a top support seat 5 arranged above the assembly seat 3, and a fixing cylinder 4 is fixed between the top support seat 5 and the assembly seat 3;

[0021] The power mechanism includes a motor 16 mounted on the inner wall of the bottom end of the control cabinet 1, and the output shaft of the motor 16 and the outer wall of the bottom end of the turntable 2 are both tightly sleeved with pulleys, and a transmission belt is connected between the two pulleys;

[0022] When in use, the can product to be shrunken is inverted on the top support seat 5 in advance, and then the motor 16 is turned on. The output shaft of the motor 16 can drive the turntable 2 under the action of the transmission belt, so that the can product rotates at a uniform speed along with the turntable 2, and then in the process of rotation of the can product, the shrinking plate contacts the outer wall of the can product, so that the shrinking plate can shrink the can product evenly for one circle.

[0023] Further, refer to Figure 3 As shown, it is worth noting that four groups of inner supporting molds 6 are arranged around the outer periphery of the fixed cylinder 4, and a pressure member for causing the four groups of inner supporting molds 6 to move away synchronously is arranged on the inner side of the fixed cylinder 4;

[0024] Through the setting of a pressure mechanism and a plurality of inner support molds 6, when the necked can product is poured onto the top support seat 5, the pressure component is used to cause the four groups of inner support molds 6 to slide synchronously away from the fixed tube 4 until the inner support molds 6 are close to the inner wall of the can product. In this way, the four groups of inner support molds 6 cooperate with each other to firmly support the product, enhance the connectivity between the product and the fixed tube 4, and enable the product to be rotated by the fixed tube 4 even when subjected to the pressure of the necking plate, thereby ensuring the progress of the necking process.

[0025] Further, refer to Figure 2 and Figure 3 As shown, it is worth noting that the pressure-applying component includes an extrusion member arranged in the middle of the inner cavity of the fixed cylinder 4 and four groups of sliders 8 distributed around the outer periphery of the extrusion member. The ends of the four groups of sliders 8 away from the extrusion member all pass through the fixed cylinder 4 and are respectively fixedly connected to the four groups of inner support molds 6. The top surface of the assembly seat 3 is provided with a receiving groove 7 for the extrusion member to pass through and shrink.

[0026] The extrusion member includes a movable seat 9 slidably disposed in a cube shape inside the fixed cylinder 4 and an extrusion seat 10 fixed on one side of the movable seat 9 corresponding to the receiving groove 7 in a quadrangular pyramid shape. The end of the slider 8 away from the inner support mold 6 is in an inclined surface shape and fits with the inclined edge of the extrusion seat 10.

[0027] After the can product is inverted on the top support seat 5, the movable seat 9 and the extrusion seat 10 are moved downward to the inner side of the accommodating groove 7 as a whole. The extrusion seat 10 can synchronously squeeze the four groups of sliders 8 during this activity, so that the four groups of sliders 8 are forced to pass through the fixed tube 4 and push the corresponding inner support molds 6. The four groups of inner support molds 6 are synchronously forced to move away from the fixed tube 4 to support the inner wall of the can body in multiple directions.

[0028] Further, refer to Figure 3 As shown, it is worth noting that a movable groove 11 is provided on the top surface of the slider 8, a pull rod 12 is hinged in the movable groove 11, and a connecting block 13 which is vertically fixed to the side wall of the movable seat 9 is hinged at the end of the pull rod 12;

[0029] Through the setting of the pull rod 12, when the extrusion seat 10 and the movable seat 9 slide up as a whole, the slider 8 can be pulled by the pull rod 12 during the sliding process of the movable seat 9, causing the slider 8 to shrink toward the inside of the fixed cylinder 4, and then causing the inner support mold 6 to slide toward the fixed cylinder 4, thereby releasing the internal support effect on the can product, thereby facilitating the subsequent removal of the can product from the top support seat 5.

[0030] Further, refer to Figure 2 and Figure 3 As shown, it is worth noting that a cylinder 14 is also installed on the inner wall of the bottom end of the control cabinet 1, and a movable rod 15 is fixed to the telescopic end of the cylinder 14. The end of the movable rod 15 passes through the turntable 2 and the assembly seat 3 in sequence and penetrates into the inner side of the fixed cylinder 4. The movable seat 9 and the extrusion seat 10 are both tightly sleeved on the rod body of the movable rod 15;

[0031] When the cylinder 14 is started, the telescopic end of the cylinder 14 can act on the movable rod 15 to slide up and down, thereby providing power for the movable seat 9 and the extrusion seat 10 as a whole inside the fixed cylinder 4.
