Description

Technical Field

[0001] This utility model relates to the field of edge-sealing injection molding technology, specifically to a heating device for edge-sealing injection molding of automotive glass. Background Technology

[0002] Car bodies are not absolutely rigid and undergo torsional deformation and vibration during driving. The directly bonded glass edges are the junction of hard glass and a rigid car body, making them prone to stress concentration. Under impact or prolonged vibration, this can cause the glass to crack from the edge. Injection-molded glass is an advanced automotive component that combines glass with a polymer frame through injection molding, achieving a perfect combination of flexible materials and rigid glass. Injection-molded glass for sunroofs is widely used; however, current technology typically involves placing cool glass directly into a hot mold. Uneven heating and cooling can easily cause the glass to crack during injection molding, increasing production costs. Utility Model Content

[0020] like Figure 1 The diagram shown is a schematic representation of an embodiment of the automotive glass injection molding edge-sealing glass heating device without glass placement. Figure 2 The diagram shown is a schematic representation of the placement of the automotive glass injection molding edge-sealing glass heating device according to an embodiment of this utility model. Figure 1 and Figure 2The heating device includes a heating chamber 1, multiple sets of chains 2, support frames 3, and a running mechanism 4. Specifically, to allow the glass 15 to be placed in the heating chamber 1 for heating, multiple sets of chains 2 are arranged on opposite sides inside the heating chamber 1. The chains 2 are arranged in pairs, and each set of chains 2 rotates coaxially to be driven to rotate. To allow the glass 15 to be driven into the heating chamber 1 along with the rotation of the chains 2, multiple support frames 3 are provided on each chain 2 to support the glass 15. By placing the glass 15 on the support frames 3, the rotation of the chains 2 drives the support frames 3 to rotate, thereby causing the glass 15 to rise and fall inside the heating chamber 1, so that the glass 15 is heated during the descent inside the heating chamber 1. To facilitate the removal of heated glass 15 after it has been filled into the heating chamber 1, a running structure is installed at the bottom of the heating chamber 1. A suction cup 5 is mounted on the running mechanism 4. When the glass 15 is lowered to the bottom of the heating chamber 1, the suction cup 5 adheres to the glass 15, and the running mechanism 4 removes the heated glass 15 from the heating chamber 1 for the next process. By placing the glass 15 in the heating chamber 1 for heating, its temperature rises, preventing it from cracking due to contact with the hot mold during the subsequent injection molding edge-wrapping process. This saves production costs, and the heating operation in the heating chamber 1 is simple and convenient.

[0021] In one embodiment of this utility model, in order to prevent the glass 15 from shifting in position when placed in the heating box 1, the heating device further includes multiple limiting plates 6, which are respectively arranged between each set of chains 2 and on the opposite side of the running mechanism 4 from the side that moves out of the heating box 1, so as to limit the position of the glass 15 in three directions of the heating box 1, thereby preventing the glass 15 from shifting in position, reducing the damage caused by the glass 15 being driven down by the chain 2 due to position shift, and saving costs.

[0022] In one embodiment of this utility model, in order to make the heating box 1 adaptable to different types of glass 15, the heating device includes a left and right adjustment mechanism 7, which is disposed on one side inside the heating box 1 and connected to a chain support frame 8 that supports a set of chains 2, so as to adjust the distance between one set of chains 2 and another set of chains 2 to adapt to different types of glass 15.

[0023] In one embodiment of this utility model, in order to enable the chain 2 to move and adapt to different types of glass 15, multiple sets of chains 2 are arranged on both sides inside the heating box 1 through chain support frame 8, and the heating device includes side brackets 9, which are respectively arranged on both sides inside the heating box 1. The chain support frame 8 can move back and forth along the side brackets 9 and is fixed to the side brackets 9 by bolts.

[0024] In one embodiment of this utility model, in order for the chain 2 to rotate after the glass 15 is placed on the support frame 3, and drive the glass 15 to descend into the heating box 1 for heating, the heating device also includes a sensor 10, which is set on the limiting plate 6 on the opposite side of the running mechanism 4 from the side that moves out of the heating box 1, for sensing the glass 15, so as to give a feedback signal to make the chain 2 rotate to drive the glass 15 to descend into the heating box 1, and rotate to drive the empty support frame 3 to rise, so as to place the next piece of glass 15.

[0025] In one embodiment of this utility model, in order to allow the operating mechanism 4 to remove the heated glass 15, guide rails 11 are provided on both sides of the operating mechanism 4, so that the operating mechanism 4 can move along the guide rails 11 to move the glass 15 out from the bottom of the heating box 1 for the next process. In one embodiment of this utility model, in order to prevent the glass 15 from being placed even if there is an operational malfunction during the placement process, the heating device also includes an indicator light 12, which is set on one side of the heating box 1 to issue an alarm signal in the event of an operational malfunction in the heating box 1.

[0026] In one embodiment of the present invention, the heating device further includes an adjustment component 13 connected to each limiting plate 6, for adjusting the position of the limiting plate 6 to adjust the position of the control glass 15 so that the glass 15 is heated evenly.

[0027] In one embodiment of the present invention, in order to facilitate the movement of the heating device to adapt to different production lines, the heating device also includes a plurality of casters 14, which are disposed at the bottom of the heating box 1 for moving the heating box 1.

[0028] Through the above technical solution, this utility model provides a heating device for automotive glass injection molding edge banding. This heating device uses multiple sets of chains 2 arranged on opposite sides inside a heating chamber 1, in pairs, with each set of chains 2 rotating coaxially. A support frame 3 is mounted on the chains 2 to support the glass 15, causing the glass 15 to rise and fall inside the heating chamber 1 as the chains 2 rotate. This allows the glass 15 to be heated as it descends within the heating chamber 1. A running mechanism 4 is located at the bottom of the heating chamber 1 and is equipped with suction cups 5 to attract the glass 15 when it descends to the bottom of the heating chamber 1, and to remove the heated glass 15 from the heating chamber 1. This heating device, using chains 2 and support frames 3 to place the glass 15 into the heating chamber 1 for heating, prevents the glass 15 from cracking due to temperature when placed in the injection molding edge banding mold, reduces production costs, is compatible with various types of glass 15, and is convenient and simple to operate.
