When the plastic product is solidified, some heat will also be dissipated outward through the exhaust hole, which cooperates with the cooling system to cool the plastic product. However, if this part of the heat is discharged directly, it will cause a certain degree of waste. For this reason, we propose an energy-saving and consumption-reducing injection molding machine.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Example 1

[0030] See also Figure 1-5 , the utility model provides a technical solution:

[0031] An energy-saving and consumption-reducing injection molding machine includes a machine body 1, a barrel 2 and a fixed mold 3. The machine body 1 and the barrel 2 are both common structures, and no further description is given here. The fixed mold is also a common structure, but the cooling component 4 inside the fixed mold is appropriately adjusted to cooperate with the energy-saving pipe 10 to improve the heat utilization of the cooling pipe 44.

[0032] A fixed cavity 8, the fixed cavity 8 is arranged in the fixed membrane;

[0033] An exhaust hole 9 is provided on the fixed film and the fixed cavity 8;

[0034] An energy-saving tube 10, which is arranged between the exhaust hole 9 and the barrel 2;

[0035] The cooling component 4 is arranged on the machine body 1 and is used to cooperate with the energy-saving pipe 10 to cool the plastic products.

[0036] The cooling component 4 includes a cold water tank 41 and an intermediate tank 42 arranged on the machine body 1. A water pump is arranged in the cold water tank 41, and a water inlet pipe 43 is arranged on the water pump. A plurality of interconnected cooling pipes 44 are arranged in the fixed cavity 8. A drain pipe 45 is arranged on the intermediate tank 42. The water inlet pipe 43 and the drain pipe 45 are respectively connected to the cooling pipes 44 located at both ends.

[0037] An installation box 11 is provided on the outer side of the fixed mold 3 near the water inlet pipe 43. The installation box 11 is connected to the exhaust hole 9, and a vent hole 12 is provided on the installation box 11. The installation box 11 is provided with a driving component 5 used in conjunction with the water inlet pipe 43, which is used to transfer the heat in the exhaust hole 9 to the barrel 2 when the plastic product is cooled;

[0038] The driving component 5 includes a fan blade 51 arranged in the installation box 11, and a transmission member 6 for driving the fan blade 51 to rotate is arranged in the installation box 11. A connecting pipe 52 connected to the water inlet pipe 43 is arranged on the water inlet pipe 43, and an energy-saving member 7 for driving the transmission member 6 to work when water enters the water inlet pipe 43 is arranged on the connecting pipe 52;

[0039] The transmission member 6 includes a transmission shaft 1 61 rotatably arranged in the installation box 11, a transmission shaft 2 62 rotatably arranged in the installation box 11 near the exhaust hole 9, a pulley 63 is arranged on the transmission shaft 1 61 and the transmission shaft 2 62, a synchronous belt 64 is arranged between the two pulleys 63, and the fan blade 51 is arranged on the transmission shaft 2 62;

[0040] The energy-saving member 7 includes a main shaft 71 rotatably arranged in the connecting pipe 52 through a sealed bearing, a water wheel blade 72 is arranged on the main shaft 71, one side of the water wheel blade 72 faces the water inlet pipe 43, one end of the main shaft 71 extends to the inside of the installation box 11, and the main shaft 71 and the transmission shaft 1 61 are respectively provided with bevel gears 73 used in conjunction with each other;

[0041] The outer side of the energy-saving pipe 10 is provided with a heat-insulating layer 15 .

[0042] When in use, the staff pours the plastic into the barrel 2. When starting work, the plastic in the barrel 2 is not preheated and directly enters the injection molding system. When the first plastic product is cooled, the water pump is started, and the water in the cold water tank 41 enters the cooling pipe 44 through the water inlet pipe 43, and is discharged from the drain pipe 45 into the intermediate box 42. During the process, the water wheel blade 72 in the connecting pipe 52 is impacted by the water flow and rotates, which drives the main shaft 71 to rotate, and the main shaft 71 drives the bevel gear 73 to rotate, and then drives another bevel gear 73 and the transmission shaft 1 61 to rotate. Under the action of the pulley 63 and the synchronous belt 64, the bottom transmission shaft 2 62 and the fan blade 51 are driven to rotate, so as to take away the heat generated by the plastic product and the heat in the cooling pipe 44, and transmit it to the bottom of the barrel 2 through the energy-saving pipe 10, so as to preheat the plastic at the bottom, so that the subsequent plastics are all preheated. The step reduces the loss of this part of heat to a certain extent, achieves energy saving and consumption reduction, and is conducive to the green development of the enterprise.

[0043] Example 2

[0044] See also Figure 6 Different from Example 1, a conical tube 13 is sleeved on the outer side of the barrel 2, one end of the energy-saving tube 10 is connected to the conical tube 13, and a through hole 14 is opened at one end of the conical tube 13 away from the energy-saving tube 10.

[0045] When in use, the staff pours the plastic into the barrel 2. When the work starts, the plastic in the barrel 2 is not preheated and directly enters the injection molding system. When the first plastic product cools down, the water pump starts, and the water in the cold water tank 41 enters the cooling pipe 44 through the water inlet pipe 43, and is discharged from the drain pipe 45 into the intermediate box 42. During the process, the water wheel blades 72 in the connecting pipe 52 are impacted by the water flow and rotate, which drives the main shaft 71 to rotate, and the main shaft 71 drives the bevel gear 73 to rotate, and then drives another bevel gear 73 and the transmission shaft 61 to rotate. Under the action of the pulley 63 and the synchronous belt 64, the bottom transmission shaft 62 and the fan blade 51 are driven to rotate, so as to take away the heat generated by the plastic products and the heat in the cooling tube 44, and enter the conical tube 13 through the energy-saving tube 10, and then transfer it to the plastic in the barrel 2, but the gas will not blow the plastic directly, which can avoid the situation where the energy-saving tube 10 is blocked when there is no air in the energy-saving tube 10, so that the subsequent plastics are all preheated. To a certain extent, the loss of this part of heat is reduced, energy saving and consumption reduction are achieved, which is conducive to the green development of the enterprise.
