[0024] Combination Figure 1 and Figure 3-Figure 4 A thermoplastic plastic particle forming mold includes a mold body 1, a support plate 2 arranged at the bottom end of the mold body 1, and a support leg 21 fixedly connected to the bottom end of the support plate 2, a collecting drawer 3 is arranged above the support plate 2, a cooling component 4 for cooling plastic particles is arranged below the collecting drawer 3, and a first air vent 31 is opened on the lower surface of the collecting drawer 3.

[0025] The utility model is further described below in conjunction with embodiments.

[0026] Embodiment 1:

[0027] See also Figure 2-Figure 6 The cooling assembly 4 includes a cooling water tank 41 fixedly connected to the bottom end of the support plate 2, a cooling box 43 fixedly connected to the inside of the support plate 2, a water pump 42 fixedly connected to one side of the cooling water tank 41, a cooling water pipe 44 arranged inside the cooling box 43, a box cover 45 fixedly connected to the bottom end of the cooling box 43, a through hole opened on the lower surface of the box cover 45, and an exhaust fan 46 arranged at the bottom end of the through hole. One end of the cooling water pipe 44 penetrates the cooling box 43 and is fixedly connected to the water pump 42. The other end of the cooling water pipe 44 penetrates and is connected to both the cooling box 43 and the cooling water tank 41. A second air vent 431 is opened on the upper surface of the cooling box 43. The second air vent 431 is aligned with the first air vent 31. It should be arranged that the cooling water in the cooling water pipe 44 is pumped out and transported to the cooling water pipe 44 through the water pump 42, and then circulated back to the cooling water tank 41 through the cooling water pipe 44, so as to form a closed cooling circulation system, which can effectively take away the heat inside the cooling box 43, and the external air is pumped into the cooling box 43 through the exhaust fan 46 to generate air flow, and the air flow is affected by the low temperature through the cooling water pipe 44 and cooled down, and this part of the colder air flow then enters the collecting bin 3 through the second air vent 431, the third air vent 52 and the first air vent 31 in turn, so as to facilitate the cooling of the plastic particles inside the collecting bin 3 and reduce the influence of the ambient temperature on the cooling of the exhaust fan 46.

[0028] A filter plate 451 is fixedly connected to the inside of the passage, and a filter hole 4511 is opened on the lower surface of the filter plate 451. The filter holes 4511 on the filter plate 451 are convenient for effectively blocking dust, impurities and other pollutants from entering the passage, ensuring that the air introduced by the exhaust fan 46 is clean.

[0029] A protective cover 5 is movably provided on the outer surface of the mold body 1, and a third air port 52 is provided on the lower surface of the protective cover 5. The lower surface of the protective cover 5 is in contact with the upper surface of the cooling box 43. The third air port 52 and the second air port 431 are correspondingly arranged. The protective cover 5 prevents plastic particles from splashing. The corresponding arrangement of the third air port 52 and the second air port 431 ensures that the cold air flow enters the collecting drawer 3 through the second air port 431, the third air port 52 and the first air port 31 in sequence to cool the plastic particles.

[0030] A slide groove 51 is provided on the inner wall of the protective cover 5, and the collecting drawer 3 is slidably connected to the slide groove 51. A handle 32 is fixedly connected to one end of the collecting drawer 3. The sliding connection between the collecting drawer 3 and the slide groove 51 makes it easy to quickly pull out and push back the collecting drawer 3, so as to facilitate the removal of the plastic particles inside the collecting drawer 3.

[0031] A clamping block 53 is fixedly connected to one end of the protective cover 5 close to the mold body 1. A clamping slot 11 is opened at one end of the mold body 1. The clamping block 53 is engaged with the clamping slot 11. Through the engaging design of the clamping block 53 and the clamping slot 11, the protective cover 5 can be quickly installed and disassembled without the assistance of tools.

[0032] A fixing plate 6 is fixedly connected to the bottom end of the mold body 1, and a mounting plate 61 is fixedly connected to the end of the fixing plate 6 away from the protective cover 5. A locking bolt 611 is threadedly connected between the mounting plate 61 and the support plate 2. The mold body 1 is fixed to the top of the support plate 2 by the locking bolt 611. Removing the locking bolt 611 facilitates separation of the mold body 1 from the support plate 2.

[0033] When in use, the block 53 is engaged with the slot 11, and the protective cover 5 prevents the plastic particles from splashing. At this time, the lower surface of the protective cover 5 contacts the upper surface of the cooling box 43, and the plastic particles are cut through the mold body 1. The water pump 42 is started, and the cooling water in the cooling water pipe 44 is pumped out and transported to the cooling water pipe 44 through the water pump 42, and then circulated back to the cooling water tank 41 through the cooling water pipe 44, forming a closed cooling circulation system, which can effectively take away the heat inside the cooling box 43, and the external air is pumped into the cooling box 43 through the exhaust fan 46 to generate air flow. The air flow is affected by the low temperature through the cooling water pipe 44 and is cooled. This part of the colder air flow then enters the collection drawer 3 through the second air vent 431, the third air vent 52 and the first air vent 31 in turn, so as to facilitate cooling the plastic particles inside the collection drawer 3 and reduce the influence of the ambient temperature on the cooling of the exhaust fan 46. After cooling, the collection drawer 3 is pulled out by the handle 32, so as to facilitate taking out the plastic particles inside the collection drawer 3.
