A fan 35 is fixedly connected to one side of the rectangular cover 34, and the output end of the fan 35 is connected to the inner wall of the rectangular cover 34. A pressure block 311 is fixedly connected to one side of the upper mold 2, and the pressure block 311 corresponds to the position of the rectangular cover 34. By setting a cooling device 3, when the upper mold 2 moves closer to the lower mold 1, the upper mold 2 drives the pressure block 311 to move. When the upper mold 2 and the lower mold 1 move to be completely merged, the pressure block 311... 11. The rectangular cover 34 is squeezed, so that the rectangular cover 34 is completely inserted into the concave frame 31 under the pressure of the pressure block 311, so that the rectangular cover 34 and the fan 35 can be quickly retracted. When the upper mold 2 leaves the lower mold 1, under the reaction force of the spring 33, the spring 33 pushes the circular hole plate 32 to move along the inside of the concave frame 31 towards the upper mold 2. The circular hole plate 32 drives the rectangular cover 34 to move towards the upper mold 2. The rectangular cover 34 drives the fan 35 to move towards the upper mold 2. When the rectangular cover 34 moves to the gap position between the upper mold 2 and the lower mold 1, the fan 35 is started, so that the fan 35 delivers airflow into the rectangular cover 34. The airflow blows onto the surface of the electrical connector product of the lower mold 1 through the opening of the rectangular cover 34, so as to achieve auxiliary cooling of the newly formed electrical connector product, reduce the residual heat on the surface of the product after molding, and prevent personnel from accidentally burning their hands when picking up the material, thus improving the safety of personnel picking up the material and the cooling efficiency of the product.

The filter plate 310 is located at the edge of the inner wall of the rectangular cover 34. By setting the filter plate 310, the filter plate 310 can intercept large impurities or debris from the outside, reducing the entry of large impurities or debris into the rectangular cover 34, which would cause the inside of the rectangular cover 34 to become dirty and clog the output end of the fan 35. A rubber pad 39 is fixedly connected to one side of the rectangular cover 34. The surface of the rubber pad 39 is rectangular. By setting the rubber pad 39, the rubber pad 39 can separate the pressure block 311 from the surface of the rectangular cover 34, reducing the large wear caused to the surface of the rectangular cover 34 when the pressure block 311 squeezes it.

[0032] Reference Figure 3 and Figure 4As shown, this embodiment discloses a connecting device 4 including a locking frame 41, which is fixedly connected to the lower mold 1.

A locking block 46 is fixedly connected to one side of the concave frame 31, and a circular groove 47 is provided on one side of the locking block 46. The surface of the locking block 46 is slidably connected to the inner wall of the locking frame 41. The size and shape of the bolt 43 are adapted to the size and shape of the inner wall of the circular groove 47. By setting the connecting device 4, the device can be manually moved first. The concave frame 31 moves the locking block 46. When the locking block 46 moves to the position where it is fully inserted into the locking frame 41, the inner wall of the circular groove 47 coincides with the inner wall of the threaded hole 42. At this time, the bolt 43 is manually rotated so that the bolt 43 is turned into the position of the threaded hole 42 and the circular groove 47 to fix the locking block 46 in position, thereby achieving the assembly and fixation of the cooling device 3 and the lower mold 1.

A reinforcing plate 45 is fixedly connected to one side of the positioning frame 41. The reinforcing plate 45 is fixedly connected to the lower mold 1. By setting the reinforcing plate 45, the connection strength between the positioning frame 41 and the lower mold 1 can be increased, reducing the possibility of the positioning frame 41 separating from the lower mold 1 when subjected to force.

[0034] Working principle: First, the upper mold 2 and lower mold 1 are installed on the injection molding machine. Then, the heating system inside the injection molding machine is used to melt the plastic particles into a plastic fluid. Then, under the drive of the injection molding machine, the upper mold 2 and lower mold 1 are merged, and the plastic fluid is injected into the cavity between the upper mold 2 and lower mold 1. After cooling, the injection molding of the pin connector product is achieved.

[0035] First, manually move the concave frame 31, causing it to move the locking block 46. When the locking block 46 moves to the position where it is fully inserted into the locking frame 41, the inner wall of the circular groove 47 coincides with the inner wall of the threaded hole 42. At this time, manually rotate the tightening block 44, causing it to rotate the bolt 43, which then rotates into the position of the threaded hole 42 and the circular groove 47 to fix the locking block 46 in place. This achieves the assembly and fixation of the cooling device 3 and the lower mold 1. When the upper mold 2 moves closer to the lower mold 1, it causes the pressure block 311 to move. When the upper mold 2 and the lower mold 1 move to the position where they are fully joined, the pressure block 311 presses against the rectangular cover 34, causing the rectangular cover 34 to be fully inserted under the pressure of the pressure block 311. The rectangular cover 34 and the fan 35 are quickly retracted into the concave frame 31. When the upper mold 2 leaves the lower mold 1, the reaction force of the spring 33 pushes the circular hole plate 32 to move closer to the upper mold 2 along the inside of the concave frame 31. The circular hole plate 32 drives the rectangular cover 34 to move closer to the upper mold 2. The rectangular cover 34 drives the fan 35 to move closer to the upper mold 2. When the rectangular cover 34 moves to the gap position between the upper mold 2 and the lower mold 1, the fan 35 is activated, so that the fan 35 delivers airflow into the rectangular cover 34. The airflow blows onto the surface of the electrical connector product of the lower mold 1 through the opening of the rectangular cover 34, thereby achieving auxiliary cooling of the newly formed electrical connector product.
