[0028] A plastic injection molding machine according to an embodiment of the present invention will be described below with reference to the drawings.

[0029] Reference Figure 1 , an embodiment of an injection molding machine is provided by the present utility model.

[0030] An injection molding machine according to an embodiment of the present utility model includes an injection mechanism, a molding die, and a blanking mechanism.

[0031] Specifically, the injection mechanism is used to inject plastic raw materials and includes an injection body; the molding die includes a fixed die 100, a movable die 110, and a press 120 that drives the movable die 110 to approach or move away from the fixed die 100. The fixed die 100 and the movable die 110 are arranged horizontally opposite to each other. The fixed die 100 has a first forming die part 370 and a second forming die part 380. The movable die 110 has two first moving templates 140 and a first motor 160 that drives the first moving templates 140 to rotate. The first moving templates 140 and the first forming die part 370 cooperate to form a first molding cavity 170, and the first moving templates 140 and the second forming die part 380 cooperate to form a second molding cavity 180; the blanking mechanism includes a material transfer assembly and a conveying assembly. The material transfer assembly includes a material taking part and a power part that drives the material taking part to move. The material taking part is used to obtain the product on the second molding cavity 180. The conveying assembly includes a conveyor belt 190 located below the molding die and a second motor that drives the conveyor belt 190 to rotate. The conveyor belt 190 is used to convey the product from the material taking part.

[0032] It can be understood that multiple first molding cavities 170 can be provided, and the number of the second molding cavities 180 is the same as that of the first molding cavities 170, thereby improving the molding efficiency.

[0033] In some embodiments of the present utility model, the material taking part includes a connecting frame 200 and a plurality of suction heads 210 arranged on the connecting frame 200. The suction heads 210 are used to adsorb the product on the second molding cavity 180.

[0034] Therefore, the vacuum suction heads 210 are used to adsorb the product after molding in the second molding cavity 180, making the method of separating the injection molded product from the mold simple. Moreover, the power part is used to drive the suction heads 210 to accurately place the injection molded product on the conveyor belt 190.

[0035] In some embodiments of the present utility model, the power part includes a lifting cylinder 220 and a slide table cylinder 230 that are connected to each other. The lifting cylinder 220 drives the slide table cylinder 230 to lift, and the slide table cylinder 230 is connected to the connecting frame 200.

[0036] Therefore, after demolding, the lifting cylinder 220 can be used to drive the suction heads 210 to approach the second molding cavity 180, and the slide table cylinder 230 can be used to drive the suction heads 210 to move horizontally, so that the suction heads 210 can suck the injection molded product. Thus, the blanking operation is simple, the power source of the blanking mechanism is less, and the manufacturing cost of the equipment is reduced.

[0037] In some embodiments of the present utility model, with reference to Figure 1 and Figure 3 , a guiding frame 240 is provided above the conveyor belt 190. The guiding frame 240 is provided with a guiding channel 250 extending vertically, and the guiding channel 250 is used to guide the products in the second forming cavity 180 to fall onto the conveyor belt 190.

[0038] It can be understood that the guiding channel 250 is located below the second forming cavity 180. After the suction head 210 adsorbs the injection molded product, the injection molded product can fall into the guiding channel 250, and the guiding channel 250 guides the injection molded product to accurately fall onto the conveyor belt 190.

[0039] In some embodiments of the present utility model, the guiding channel 250 is tapered along the direction close to the conveyor belt 190.

[0040] It can be understood that the upper cross-sectional area of the guiding channel 250 is large, which is beneficial for the guiding channel 250 to receive the injection molded product released by the suction head 210, and avoids the injection molded product from not accurately falling into the guiding channel 250.

[0041] In some embodiments of the present utility model, limiting plates 260 are provided on the horizontal two sides of the conveyor belt 190. The limiting plates 260 are located below the guiding frame 240, and the limiting plates 260 are used to limit the products on the conveyor belt 190 in the horizontal direction.

[0042] Therefore, when the injection molded product slides from the guiding channel 250 onto the conveyor belt 190, the limiting plates 260 can limit the injection molded product to prevent the injection molded product from deviating from the conveyor belt 190.

[0043] In some embodiments of the present utility model, with reference to Figure 2 , the moving mold 110 has a connecting template 270. The connecting template 270 is provided with two positioning cavities 280. The two positioning cavities 280 are arranged side by side, and the positioning cavities 280 accommodate the first moving template 140. Thus, the position of the first moving template 140 is ensured to be accurate, and further, it is ensured that the first forming and the second forming can be carried out smoothly.

[0044] In some embodiments of the present utility model, the forming mold includes a mold base 300. The connecting template 270 is provided with a rotating shaft 290, and the rotating shaft 290 is rotatably arranged on the mold base 300.

[0045] In a further embodiment of the present utility model, the output end of the first motor 160 is coaxially provided with a driving gear 310, the rotating shaft 290 is coaxially provided with a driven gear 320, and the driving gear 310 and the driven gear 320 are meshed.

[0046] Therefore, the first motor 160 is used to drive the driving gear 310 to rotate. The driving gear 310 and the driven gear 320 are in meshing transmission, so that the driven gear 320 can drive the first moving template 140 to rotate through the rotating shaft 290, enabling the first moving template 140 to cooperate with the first forming die part 370 to form the first forming cavity 170 for primary injection molding. After the first moving template 140 rotates to a certain position, the first moving template 140 can cooperate with the second forming die part 380 to form the second forming cavity 180 for secondary injection molding.

[0047] In some embodiments of the present utility model, the injection molding mechanism has a first injection nozzle 330 and a second injection nozzle 340. The first forming die part 370 is connected with a first runner 350, and the second forming die part 380 is connected with a second runner 360. The first runner 350 communicates the first injection nozzle 330 and the first forming cavity 170, and the second injection nozzle 340 communicates the second injection nozzle 340 and the second forming cavity 180. Thus, plastic raw materials can enter the first forming cavity 170 and the second forming cavity 180 for molding.

[0048] Therefore, this embodiment has the following effects:

[0049] 1. By providing the fixed mold 100, the movable mold 110 and the press 120, the present utility model uses the press 120 to drive the movable mold 110 to approach the fixed mold 100, so that the first moving template 140 and the first forming die part 370 cooperate to form the first forming cavity 170, and the plastic liquid is formed once in the first forming cavity 170. The first motor 160 is used to drive the first moving template 140 to rotate, so that the second movable mold plate 110 and the second forming die part 380 cooperate to form the second forming cavity 180, and the plastic liquid is formed twice in the second forming cavity 180. At the same time, the fixed mold 100 and the movable mold 110 are horizontally arranged opposite to each other. When the fixed mold 100 and the movable mold 110 are demolded, a receiving space is formed, and the material transfer assembly can enter the receiving space and obtain the product in the second forming cavity 180. Moreover, the product is conveyed to the next process by the conveying assembly, thus replacing manual blanking, improving the blanking efficiency, and improving the conveying efficiency.

[0050] 2. By providing the material taking part, the power part, the conveyor belt 190 and the second motor, the present utility model uses the power part to drive the material taking part to move, so that the material taking part approaches the second forming cavity 180 and obtains the injection molded product. Then, the material taking part places the injection molded product on the conveyor belt 190, and the second motor is used to drive the conveyor belt 190 to convey the injection molded product.
