Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0020] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0021] Referring to Figures 1-3 , a multi-station injection mold includes a base 1. A plurality of symmetrically arranged support rods 2 are provided at the lower end of the base 1. A fixed frame 3 is provided at the upper end of the base 1. Two symmetrically arranged telescopic cylinders 4 penetrate through the upper end of the fixed frame 3. A connecting plate 5 is jointly provided at the lower ends of the two telescopic cylinders 4. An upper mold 6 is provided at the lower end of the connecting plate 5. A plurality of circumferentially arranged lower molds 11 are provided above the base 1. Through the arrangement of the plurality of lower molds 11, when the upper mold 6 operates with one of the lower molds 11, people can take and perform other operations on the products in other molds, so that the equipment is always in a working state, avoiding the equipment being in a dormant state when people take the materials and reducing the injection rate.

[0022] A rotating groove 7 is opened at the upper end of the base 1. A rotating plate 8 is provided in the rotating groove 7. An installation mechanism for installing the lower mold 11 is provided at the upper end of the rotating plate 8. The installation mechanism includes a plurality of circumferentially arranged installation grooves 9 opened at the upper end of the rotating plate 8. A plurality of groups of circumferentially arranged fixing columns 17 are provided at the upper end of the rotating plate 8. The plurality of groups of fixing columns 17 are respectively matched with the plurality of installation grooves 9. Two limiting plates 18 are provided on the outer walls of the plurality of fixing columns 17.

[0023] A matching mechanism matched with the installation mechanism is provided on the outer walls of the plurality of lower molds 11. The matching mechanism includes a plurality of circumferentially arranged connecting ears 12 provided on the outer walls of the lower molds 11. Matching grooves 16 matched with the fixing columns 17 and the limiting plates 18 are opened on the plurality of connecting ears 12. By staggering the two limiting plates 18 with the matching grooves 16, the connection between the connecting ears 12 and the fixing columns 17 is restricted by the plurality of limiting plates 18, thereby realizing the quick installation of the lower mold 11 and bringing certain convenience to people.

[0024] A plurality of circumferentially arranged internal gear rings 10 are provided at the upper end of the rotating plate 8. Gears 19 meshing with the internal gear rings 10 are provided on the outer walls of the plurality of groups of fixing columns 17.

[0025] An installation frame 13 is provided at the lower end of the base 1. A power motor 14 is provided at the upper end of the installation frame 13.

[0026] The number of the plurality of groups of fixing columns 17 is six, and the number of each group of fixing columns 17 is three.

[0027] When the utility model is in use, when installing a plurality of lower dies 11, a plurality of connecting ears 12 on the outer walls of the plurality of lower dies 11 are respectively sleeved on the outer walls of a plurality of fixing columns 17, so that the plurality of fixing columns 17 respectively extend into a plurality of mating grooves 16. Then, rotate the internal gear ring 10. By using the meshing of the internal gear ring 10 and the plurality of gears 19, the plurality of gears 19 are rotated to drive the plurality of fixing columns 17 to rotate. Thus, two limiting plates 18 on the outer walls of the plurality of fixing columns 17 rotate, so that the positions of the two limiting plates 18 are aligned with the mating grooves 16. At this time, the limiting plates 18 pass through the mating grooves 16. Then, rotate the internal gear ring 10 again to stagger the two limiting plates 18 from the mating grooves 16 (the upper ends of the limiting plates 18 are slidably connected to the lower ends of the connecting ears 12). Thus, the connection between the connecting ears 12 and the fixing columns 17 is restricted by the plurality of limiting plates 18, thereby realizing the rapid installation of the lower die 11 and bringing certain convenience to people.

[0028] And through the arrangement of the plurality of lower dies 11, when the upper die 6 operates with one of the lower dies 11, people can take and perform other operations on the products in other dies, so that the equipment is always in a working state, avoiding the equipment being in a sleep state when people take materials, and reducing the injection molding rate.
