[0043] Two limit seats 71 are provided. Two movable cavities 72 are provided on the side walls of the groove 31. The limit seats 71 are slidably arranged in the movable cavities 72. One side of the limit seat 71 is in movable contact with one side of the bottom of the lower mold 1. By providing the limit seat 71, after the upper mold 2 is placed inside the groove 31, when the two limit seats 71 slide horizontally out of the movable cavities 72, the lower mold 1 can be limited. Threaded rods 73 are rotatably installed at both sides of the base 3. One end of the threaded rod 73 is rotatably connected to one end of the limit seat 71. Rotating handles 74 are fixedly provided at the other ends of the two threaded rods 73. By rotating the rotating handle 74, the rotating handle 74 can rotate the threaded rod 73, and the threaded rod 73 can drive the limit seat 71 to slide horizontally in the movable cavity 72, entering or sliding out of the movable cavity 72;

[0044] Four extension bolts 77 are provided. The four extension bolts 77 are rotatably installed on the fixing seat 41 in a state of annular array. Four threaded holes 78 distributed in an annular array are provided on the upper end surface of the upper mold 2. One end of the extension bolt 77 is rotatably connected to the inner wall of the threaded hole 78. By providing the extension bolt 77 and the threaded hole 78, when the extension bolt 77 is separated from the threaded hole 78, the upper mold 2 can be separated from the fixing seat 41, realizing the disassembly of the upper mold 2.

[0045] Two second guide grooves 75 are provided on the side walls of the two movable cavities 72. Two second guide blocks 76 are fixedly provided at one ends of the two limit seats 71. The second guide blocks 76 are slidably connected to the inner walls of the second guide grooves 75. By providing the second guide grooves 75 and the second guide blocks 76, the second guide blocks 76 can slide horizontally along the inner walls of the second guide grooves 75, so as to guide the limit seat 71 in the horizontal direction and keep the limit seat 71 moving in the horizontal direction in the movable cavity 72.

[0046] A number of guide rollers 79 are provided. The number of guide rollers 79 are rotatably installed on the side wall of the groove 31. The bottom of the lower mold 1 is in movable contact with the outer wall of the guide roller 79. By providing the rotatable guide rollers 79, when the operator places the lower mold 1 in the groove 31, the bottom of the lower mold 1 contacts the outer wall of the guide roller 79, which is convenient for the operator to push the lower mold 1 into the innermost end of the groove 31 and also convenient for the operator to push the lower mold 1 in the groove 31 out.

[0047] Working principle: When injection molding operation is required, the operator first starts two cylinders 51. The piston ends of the two cylinders 51 extend, and the piston ends of the two cylinders 51 make the upper mold 2 vertically descend through the fixed seat 41. At the same time, the fixed seat 41 makes four fixing blocks 55, four locking rods 56 and four conical locking blocks 57 synchronously descend vertically through two lifting plates 52, two mounting brackets 53 and two U-shaped rods 54. During this process, the lower end surfaces of the four conical locking blocks 57 contact the corresponding inclined grooves 581. Under the action of the four inclined grooves 581 and four spring rods 61, the four conical locking blocks 57 and the four locking rods 56 horizontally move towards one end of the corresponding hollow sleeve 6. The four locking rods 56 squeeze the corresponding spring rods 61 to contract. When the four conical locking blocks 57 are horizontally aligned with the corresponding conical grooves 59, the four spring rods 61 extend and push the four locking rods 56 and the four conical locking blocks 57 to reset. The four conical locking blocks 57 enter the corresponding conical grooves 59 to lock the lower mold 1 and the upper mold 2. When the conical locking blocks 57 are horizontally aligned with the conical grooves 59, the lower end surface of the upper mold 2 fits against the upper end surface of the lower mold 1, thus conveniently realizing the locking of the upper mold 2 and the lower mold 1, making the upper mold 2 closely fit on the lower mold 1, and further improving the injection molding effect;

[0048] After the liquid silicone in the low-temperature state is injected into the mold cavity between the upper mold 2 and the lower mold 1, the upper mold 2 and the lower mold 1 are heated by an external heating device to raise the temperature of the upper mold 2 and the lower mold 1. After the temperature rises to the process requirement temperature, the liquid silicone solidifies and forms. After the formed liquid silicone is demolded, at this time, the upper mold 2 and the lower mold 1 are cooled. The operator first connects the air outlet of the external cold source device to the connecting pipe 43. The cold air generated by the cold source device enters the inner cavity of the fixed seat 41 through the connecting pipe 43. The cold source in the inner cavity of the fixed seat 41 flows to the upper mold 2 and the lower mold 1 through a plurality of inclined air nozzles 45 to cool the upper mold 2 and the lower mold 1, so that the upper mold 2 and the lower mold 1 are quickly cooled to the initial low-temperature state, thus conveniently realizing the rapid cooling of the upper mold 2 and the lower mold 1, and further effectively improving the molding efficiency of the plastic key;

[0049] When maintenance of the upper mold 2 and the lower mold 1 is required, the operator first rotates two rotating handles 74. The two rotating handles 74 make two threaded rods 73 rotate. The two threaded rods 73 drive two limit seats 71 to move synchronously in opposite directions, so that the two limit seats 71 move into the corresponding movable cavities 72, and then the lower mold 1 is horizontally pushed out from the groove 31. Subsequently, the operator respectively rotates four extension bolts 77 counterclockwise to disengage the four extension bolts 77 from the corresponding threaded holes 78, and then the upper mold 2 can be removed, thus conveniently realizing the disassembly of the upper mold 2 and the lower mold 1, and further facilitating the maintenance of the upper mold 2 and the lower mold 1.
