Description

Technical Field

[0001] This application relates to the field of automotive front and rear beam manufacturing technology, and in particular to a feeding mechanism for a front and rear beam injection molding device. Background Technology

[0002] The front and rear beams are crucial components of the automotive body structure, playing a vital role in the vehicle's strength, rigidity, and safety. These beams are typically manufactured using injection molding. Plastic material is heated and melted in the injection molding machine's heated barrel, forming a molten adhesive with a certain viscosity and flowability. This molten adhesive enters the manifold through the injection end of the injection molding machine and is then distributed to various gates in the mold. The manifold is equipped with a heating mechanism to ensure that the molten adhesive does not cool and solidify during transport. The mold opens, and the molten adhesive is injected into the mold cavity. After injection, the mold opens again, and the molded plastic product is removed. However, in existing injection molding equipment, workers need to manually open the heating barrel cap to fill the plastic material during the heating process. Because the surface temperature of the heating barrel is high during operation, workers are susceptible to burns, posing a safety hazard. Therefore, improvements are needed. Utility Model Content

[0003] To improve safety when filling plastic material into the heated barrel of an injection molding machine, this application provides a feeding mechanism for a front and rear beam injection molding machine.

[0004] The present application provides a material feeding mechanism for a front and rear beam injection molding device, which adopts the following technical solution:

[0005] A feeding mechanism for a front and rear beam injection molding device includes a heated cylinder with a feeding port on its peripheral wall. A conveyor belt for transporting plastic material is provided on one side of the feeding port. A rotating component is provided at the top of the heated cylinder. A rotating disk is provided on the peripheral wall of the output shaft of the rotating component. Two sets of mounting brackets are provided on the bottom wall of the rotating disk. One mounting bracket is provided with a sealing component for blocking the feeding port, and the other mounting bracket is provided with a conveying component for transporting the material on the conveyor belt toward the feeding port.

[0006] By adopting the above technical solution, when no material needs to be fed, the sealing element is above the conveyor belt and will block the feeding port to reduce heat loss during the operation of the heating cylinder. When material needs to be filled, the rotating element is started, and the conveying element comes above the conveyor belt. The conveying element drives the material on the conveyor belt to be conveyed towards the feeding port. The feeding mechanism of this application can realize automated feeding without manual operation, thereby improving the safety of feeding.

[0007] Optionally, the sealing element includes an arc-shaped plate, a heat insulation plate, and a driving cylinder. The arc-shaped plate is connected to the mounting bracket and is disposed in close contact with the side wall of the heating cylinder. A clearance groove for the heat insulation plate is provided on the side of the arc-shaped plate facing the lower feed port. The driving cylinder is disposed on the side of the arc-shaped plate away from the heating cylinder, and the piston rod of the driving cylinder passes through the arc-shaped plate and is connected to the heat insulation plate.

[0008] By adopting the above technical solution, when the rotating component drives the sealing component to rotate above the conveyor belt, the arc plate can completely cover the discharge port. After the drive cylinder is activated, the heat insulation plate disengages from the relief groove and enters the discharge port, thus achieving the covering and sealing of the discharge port, thereby reducing the heat loss during the operation of the heating cylinder.

[0009] Optionally, the shape of the heat insulation plate is adapted to the shape of the discharge port.

[0010] By adopting the above technical solution, the shape of the heat insulation plate is matched with the shape of the discharge port, which can effectively improve the sealing of the discharge port, thereby reducing the heat dissipation inside the heating cylinder.

[0011] Optionally, the conveying component includes a rotating frame, a tipping cylinder, and a rotating motor. The rotating frame is connected to the mounting frame. The rotating frame includes a horizontal plate and vertical plates disposed on the bottom walls at both ends of the horizontal plate. The tipping cylinder is rotatably connected between the two tipping cylinders. The rotating motor is disposed on the side wall of one vertical plate. The output shaft of the rotating motor passes through the vertical plate and is connected to the tipping cylinder.

[0012] By adopting the above technical solution, the rotating component starts and drives the conveyor component to rotate above the conveyor belt. The rotating motor starts and drives the tipping cylinder to rotate. When the material being transported on the conveyor belt passes under the tipping cylinder, it comes into contact with the tipping cylinder and is driven by the tipping cylinder, so that the material can continue to move towards the lower feed port at the end of the conveyor belt, thus improving the accuracy of feeding.

[0013] Optionally, the circumferential wall of the turning cylinder is provided with a plurality of soft paddles, the plurality of soft paddles being distributed along the circumferential direction of the turning cylinder, and the length of the soft paddles being set along the axial direction of the turning cylinder.

[0014] By adopting the above technical solution, the soft paddle can move the material on the conveyor belt toward the discharge port during the rotation of the tipping drum, thereby improving the efficiency of material conveying by the conveyor belt.

[0015] Optionally, baffles are provided on both sides of the conveyor belt, and the baffles have clearance notches for the sealing element and the conveying element to pass through.

[0016] By adopting the above technical solution, setting up baffles can prevent materials from detaching from the conveyor belt, thereby ensuring that the materials can be stably conveyed towards the lower feed port.

[0017] Optionally, the conveyor belt is inclined, with the end of the conveyor belt away from the heating cylinder higher than the end near the heating cylinder.

[0018] By adopting the above technical solution, the conveyor belt is inclined, which makes it easier for the material on the conveyor belt to enter the discharge port, thus effectively improving the discharge efficiency.

[0019] Optionally, the width of the conveyor belt is smaller than the width of the discharge port.

[0020] By adopting the above technical solution, setting the width of the conveyor belt to be smaller than the width of the discharge port can ensure that the plastic material on the conveyor belt can stably enter the discharge port, thereby ensuring the accuracy of the discharge.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. When no material needs to be fed, the seal is above the conveyor belt and will block the feeding port to reduce heat loss during the operation of the heating cylinder. When material needs to be filled, the rotating part is started and the conveyor comes above the conveyor belt. The conveyor drives the material on the conveyor belt to be conveyed towards the feeding port. The feeding mechanism of this application can realize automated feeding without manual operation, thereby improving the safety of feeding.

[0023] 2. The inclined design of the conveyor belt allows the material on the conveyor belt to enter the discharge port more easily, effectively improving the discharge efficiency. Attached Figure Description
