[0015] The technical solution specifically implemented in the present invention is: In a specific embodiment, Figure 1 and Figure 2 As shown, the present invention provides a pump end cover die-casting production system, including a mold unit, a blanking device and an output conveyor belt 1; The mold unit includes a fixed mold 2, a movable mold 3 and an ejection mechanism.

[0016] Adopting the above scheme, the working method of the pump end cover die-casting production system of the present invention comprises the following steps: When the movable mold 3 and the fixed mold 2 are in the mold closing state, the pump end cover 100 is formed in the mold cavity, and the grabbing mechanism is located above the output conveyor belt 1; The movable mold 3 and the fixed mold 2 are opened, and the vertical rack 7 is driven upward by the movable mold 3 to move a set distance, so that the vertical rack 7 drives the horizontal shaft 6 and the first bevel gear 11 to rotate by meshing with the circular gear 12. The first bevel gear 11 drives the vertical shaft 5 and the rotating plate 8 to rotate 90 degrees by meshing with the second bevel gear 9. The rotating plate 8 drives the grabbing mechanism to move between the movable mold 3 and the fixed mold 2, and then the ejection mechanism ejects the formed pump end cover 100 from the mold cavity, and the pump end cover 100 is grabbed by the grabbing mechanism; The movable mold 3 and the fixed mold 2 are closed again. During this process, the rotating plate 8 rotates 90 degrees in the opposite direction, and the rotating plate 8 drives the grabbing mechanism to move out from between the movable mold 3 and the fixed mold 2, so that the grabbing mechanism drives the grabbed pump end cover 100 to move above the output transmission belt 1; The grabbing mechanism releases the pump end cover 100 onto the output conveyor belt 1 , and the output conveyor belt 1 transports the pump end cover 100 to a designated location.

[0017] In another specific embodiment, Figure 1 As shown, the ejection mechanism includes an ejection plate 13 and an ejector pin 14. The ejection plate 13 is arranged below the fixed mold 2, and the ejector pin 14 is arranged on the top of the ejection plate 13. The top end of the ejector pin 14 penetrates the fixed mold 2 and extends into the cavity.

[0018] With the above solution, the ejection mechanism works as follows: when the ejection mechanism performs an ejection operation, the ejector plate 13 is driven to drive the ejector pin 14 upward, and the ejector pin 14 ejects the pump end cover 100 in the cavity; when the ejection mechanism resets, the ejector plate 13 is driven to drive the ejector pin 14 downward.

[0019] In another specific embodiment, Figure 1 and Figure 3 As shown, an annular groove 101 is provided on the outer circumferential surface of the pump end cover 100. When the pump end cover 100 is assembled, the annular groove 101 is used to install a seal; the grabbing mechanism includes a bracket 15, a connecting disc 16, a grabbing disc 17 and an electric telescopic rod 18. The bracket 15 is arranged at the bottom of the rotating plate 8, the connecting disc 16 is arranged at the bottom of the bracket 15, and two limit blocks 19 are symmetrically provided at the bottom of the connecting disc 16. The grabbing disc 17 is slidably connected between the two limit blocks 19, and two grabbing blocks 20 are symmetrically provided at the bottom of the grabbing disc 17. The pump end cover 100 is accommodated between the two grab blocks 20, and the two grab blocks 20 are respectively provided with a card bead hole 21 corresponding to the annular groove 101, the two card bead holes 21 are respectively located below the two limit blocks 19, and the two card bead holes 21 are movably provided with a card bead 22, the card bead 22 partially protrudes from the side wall of the grab block 20, and the card bead 22 is used to engage with the annular groove 101, the electric telescopic rod 18 is arranged at the bottom of the bracket 15, and the telescopic end of the electric telescopic rod 18 passes through the connecting plate 16 downward and is connected to the grab plate 17.

[0020] Adopting the above scheme, the grabbing mechanism in the present invention is designed according to the structural characteristics of the pump end cover 100. The specific operation process of the grabbing mechanism grabbing the pump end cover 100 is as follows: in the process of the ejection mechanism ejecting the pump end cover 100, the pump end cover 100 will move between the two grabbing blocks 20, and the top outer edge of the pump end cover 100 will push the card bead 22, so that the card bead 22 partially protrudes from the outer wall of the grab block 20, until the ejection mechanism is ejected into place, the top surface of the pump end cover 100 will fit with the bottom surface of the grab plate 17, and the card bead hole 21 is flush with the annular groove 101, and then the electric telescopic control is controlled. The rod 18 retracts and drives the grabbing plate 17 upward. During this process, the bottom inner edge of the limit block 19 will push the card bead 22, so that the card bead 22 partially protrudes from the inner side wall of the grab block 20 and engages with the annular groove 102 of the pump end cover 100, and the limit block 19 can block the outside of the card bead 22, so that the card bead 22 cannot move and maintains a firm engagement with the annular groove 101 to ensure the grabbing stability. After that, the grabbing plate 17 will drive the pump end cover 100 upward through the engagement between the card bead 22 and the annular groove 101, so that the pump end cover 100 is separated from the ejector pin 14. After completion, the ejection mechanism is reset.

[0021] The specific operation process of the grabbing mechanism releasing the pump end cover 100 is as follows: when the grabbing mechanism drives the grabbed pump end cover 100 to move above the output transmission belt 1, the electric telescopic rod 18 is controlled to extend and drive the grabbing plate 17 downward to place the pump end cover 100 on the output conveyor belt 1. During this process, the card bead 22 will move below the limit block 19 to release the obstruction of the limit block 19 on the card bead 22, and then release the card bead 22 from the annular groove 101, so that the pump end cover 100 can move under the drive of the output conveyor belt 1.

[0022] In another specific embodiment, Figure 1 and Figure 3 As shown, vertical sliding grooves 23 are respectively provided on the inner sides of the two limiting blocks 19 facing each other, and sliding blocks 24 that slide with the vertical sliding grooves 23 are respectively provided on both sides of the grabbing plate 17.

[0023] The above solution is adopted to achieve the sliding connection between the grabbing plate 17 and the two limiting blocks 19 .

[0024] In another specific embodiment, Figure 1 As shown, the vertical rack 7 is arranged on the side of the movable mold 3 through a fixing plate 25.

[0025] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
