With the rapid development of the plastic industry, the receiving mechanism of the injection molding machine is also constantly undergoing technological innovation and performance optimization to adapt to the ever-changing market demand. In the injection molding production process, the main responsibility of the receiving mechanism is to efficiently and accurately collect the plastic products demolded from the mold and transfer them to the next process or storage equipment. In this process, the receiving mechanism needs to overcome many challenges, such as the diversity of product shapes, the instability of demolding speed and the complexity of the production environment.

[0004] Although the above-mentioned prior art can realize the collection of plastic parts after injection molding, due to the high temperature of the plastic parts after injection molding, it is easy to produce hard contact with the conveying structure when transferred to the collection device by the robot arm, which is prone to deformation. Therefore, it does not meet the existing needs. In this regard, we propose a collection device for plastic product injection molding machines. Utility Model Content

[0005] The utility model aims to provide a material receiving device for a plastic product injection molding machine, so as to solve the problem in the above background technology that the molded plastic parts are prone to deformation when they come into contact with the material receiving device of the injection molding machine due to their high temperature.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a material receiving device for a plastic product injection molding machine, comprising a base, a material receiving mechanism is arranged on one side inside the base, a frame is installed above the inside of the material receiving mechanism, and the frame and the material receiving mechanism are fixed by bolts, transmission rollers are installed at the front and back of the inside of the frame, and the transmission rollers are rotatably connected with the frame, transmission belts are installed on both sides between the front and rear transmission rollers, and the transmission belts and the two transmission rollers are kept tensioned, elastic ropes are arranged between the transmission belts on both sides, and a plurality of elastic ropes are arranged, a sealing plate is arranged below the inside of the material receiving mechanism, an evaporator is installed below the sealing plate, and the evaporator and the material receiving mechanism are fixed by a mounting frame, a cooling air duct is arranged above the sealing plate, and at least three cooling air ducts are arranged, and a negative pressure fan is installed at the lower end of the inside of the cooling air duct.

[0007] Preferably, a driving motor is installed at the front end of one side of the frame, the housing of the driving motor is fixed to the frame by bolts, and the output shaft of the driving motor is connected to the driving roller in front by a coupling.

[0008] Preferably, an air inlet is provided at the bottom of the material receiving mechanism, a dust filter is installed inside the air inlet, and an edge of the dust filter is engaged with the air inlet.

[0009] Preferably, a condenser is provided on one side of the material receiving mechanism, the condenser is located inside the base, and the condenser and the base are fixed by a connecting frame. A compressor is installed on one side of the condenser, and the compressor, evaporator and condenser are connected by a medium delivery pipe. A cooling fan is installed at the rear end of the condenser.

[0010] Preferably, a driving device is installed on one side of the upper end of the base, a movable mold is installed on one side of the driving device, a fixed mold is installed on one side of the movable mold, an injection device is installed on one side of the fixed mold, and the material receiving mechanism is located below between the fixed mold and the movable mold.

[0011] Preferably, the interior of the cooling air duct is a conical structure.

[0012] Preferably, the elastic rope is made of synthetic fiber.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The utility model is provided with a flexible feeding structure for plastic parts, and its main body is composed of a frame, a transmission roller, a transmission belt and an elastic rope. By turning on the driving motor, its output shaft will drive the transmission roller at the front end to rotate, and cooperate with the transmission belt to realize the synchronous rotation of the transmission roller at the rear end. Since the elastic rope is arranged between the transmission belts, the transmission belt can drive the elastic rope to move synchronously at this time. The elastic rope is made of synthetic fiber material, and has the characteristics of high strength, low density, good resilience and good fatigue resistance. After the injection molded plastic parts are demolded, they are transported to the top of the elastic rope by the robot. When the plastic parts contact the elastic rope, the flexible structure of the elastic rope can reduce the hard contact with the plastic parts, and the pressure can be dispersed between multiple elastic ropes, effectively avoiding the deformation of the plastic parts during the material collection process. The device has high flexibility and can improve the protection effect while meeting the conveying requirements of the plastic parts, thereby ensuring the production quality of the plastic parts.

[0015] 2. The utility model is provided with a plastic parts cooling device. By turning on the compressor, the refrigerant is sucked into the compressor and compressed inside the compressor, so that its pressure and temperature are increased. The compressed high-temperature and high-pressure refrigerant gas enters the condenser. The refrigerant exchanges heat with the cooling medium, gradually cools and turns into liquid. The liquid refrigerant then passes through the expansion valve, and the pressure drops rapidly, causing the temperature of the refrigerant to drop accordingly. The low-temperature and low-pressure liquid refrigerant enters the evaporator, and evaporates from liquid to gas by absorbing heat from the surrounding environment. This process absorbs heat from the environment, thereby achieving a refrigeration effect. At the same time, the negative pressure fan is turned on to form a negative pressure under the sealing plate, and the cold air is blown upward through the cooling air duct. Since there are gaps between the elastic ropes used to transport plastic parts, the cold air can contact the plastic parts through the elastic ropes, thereby cooling them during the material collection process, which not only avoids deformation during the movement process, but also reduces the pressure of subsequent processing links, thereby further improving production efficiency.

[0023] When in use, by turning on the driving motor 18, its output shaft will drive the transmission roller 8 at the front end to rotate, and cooperate with the transmission belt 9 to realize the synchronous rotation of the transmission roller 8 at the rear end. Since the elastic rope 10 is arranged between the transmission belts 9, the transmission belt 9 can drive the elastic rope 10 to move synchronously. After the injection molded plastic parts are demolded, they are transported to the top of the elastic rope 10 by the robot. When the plastic parts contact the elastic rope 10, the flexible structure of the elastic rope can reduce the hard contact with the plastic parts, and the pressure can be dispersed between multiple elastic ropes, effectively avoiding the deformation of the plastic parts during the material collection process.

The housing of the driving motor 18 is fixed to the frame 7 by bolts, and the output shaft of the driving motor 18 is connected to the front driving roller 8 by a coupling, so that the elastic rope 10 can move the plastic parts.

[0026] See also Figure 1 A condenser 15 is provided on one side of the receiving mechanism 6. The condenser 15 is located inside the base 1, and the condenser 15 is fixed to the base 1 through a connecting frame.

The refrigerant exchanges heat with the cooling medium, gradually cools and turns into liquid. The liquid refrigerant then passes through the expansion valve, and the pressure drops rapidly, causing the temperature of the refrigerant to drop accordingly. The low-temperature and low-pressure liquid refrigerant enters the evaporator 13, and evaporates from liquid to gas by absorbing heat from the surrounding environment. This process absorbs heat from the environment, thereby achieving a refrigeration effect. At the same time, the negative pressure fan 19 is turned on to form a negative pressure under the sealing plate 11, and the cold air is blown upward through the cooling air duct 12. Since there are gaps between the elastic ropes used to transport plastic parts, the cold air can contact the plastic parts through the elastic ropes, thereby cooling them during the material collection process.
