[0002] Car door panels are a type of car interior. Car door panels can be made of fiber door panels, which are made by hot pressing and cold molding of fiber raw material boards. Taking hemp fiberboard as an example, the traditional production method is: manually lay the hemp fiber board in the heating area by transporting it. The heating area generally uses the upper and lower molds to heat the board to the required temperature at the same time, and then manually take it out and put the heated board into the molding mold area and arrange it in position in about 10 seconds. The molding area pressurizes and maintains the board by cold molding, and finally forms a finished product. Then manually take out the finished product and place it in the finished product storage tooling or carry out the next production process for the finished product.

[0082] In a specific embodiment, the production method includes the following steps:

[0083] Step 101: Take materials from the material pile through the feeding mechanism.

[0084] The feeding mechanism 2 of the present utility model adopts a double-station feeding form. The fixture assembly is driven by a servo motor to move on the slide rail. Through the cooperation of the first cylinder, the clamping jaws, and the first detection sensor, materials are taken from the material piles on the left and right sides; and two raw material plates can be taken at a time. It is possible to take materials without stopping the machine. FIG. 2 also generally shows the detection position of the first detection sensor 25.

[0085] Step 102: Place the raw material plate on the conveyor belt.

[0086] After the clamping jaws place the raw material plate on the conveyor belt 31, the two raw material plates are automatically aligned by the alignment component 32. The alignment position can be adjusted according to the structure of the product.

[0087] Step 103: Convey the raw material plate to the hot pressing mechanism 4 through the transmission mechanism.

[0088] Step 104: After the heat-resistant conveyor belt 46 of the hot pressing mechanism 4 is synchronized with the conveyor belt 31 of the transmission mechanism, convey the raw material plate between the upper carrier and the lower carrier.

[0089] Step 105: The upper carrier and the lower carrier are pressed together to heat and pre-press the raw material plate to obtain a preheated plate.

[0090] The conveyor belt and the Teflon belt rotate and cooperate simultaneously to convey the raw material plate into the heating area, completing the heating and pre-pressing of the raw material plate. After the preheating is completed, move the upper carrier upward (the moving height can be set), expose the preheated plate, and convey the preheated plate to the working position of the clamping jaws through the heat-resistant conveyor belt.

[0091] In a specific process, the moving plate presses down to heat the raw material plate to 220 °C (the temperature can be set in different regions according to the actual situation) and pre-press it to a thickness of 2.5 mm.

[0092] Step 106: The second clamping jaw 57 of the material supporting mechanism 5 grabs the preheated plate from the heat-resistant conveyor belt 46 and places it on the lower mold 62 of the forming mechanism 6, and the placement position is positioned through the second detection sensor to position the preheated plate with the lower mold.

[0093] Step 107: Close the lower mold and the upper mold to form the preheated plate to obtain a formed product.

[0094] The preheated plate is formed by using the cold die pressing and forming method. After forming, the forming fixture leaves the product and the excess waste on the upper mold. The water temperature of the lower mold is adjustable, the mold closing pressure is adjustable, the mold closing time is adjustable, and the mold closing position can be monitored.

[0095] Step 108: Move the upper mold upward, and the receiving plate 741 extends to the lower side of the upper mold; the upper mold places the formed product on the receiving plate 741.

[0096] After the mold is opened, the forming fixture retracts, ejects the product, and the product falls onto the receiving plate 741. After the sensor on the receiving plate detects the product, it retracts to the discharging station of the discharging rack 71.

[0097] Step 109: Output the formed product through the discharging mechanism.

[0098] Step 110: Replace the mold of the forming mechanism.

[0099] Two sets of molds can be stored in the mold changing mechanism, and the movement of two positions can be realized by driving motors or hydraulic cylinders. Automatic and semi-automatic mold changing can be achieved by the motor plus drag chain method. Multi-product co-machine production can be realized. Figure 1 The light-colored arrows show the flow direction of the raw material plate, and the dark-colored arrows show the mold replacement direction.

[0100] The utility model can realize the automated production of the fiber door panel hot pressing forming process, optimize the process flow, and reduce the labor cost; improve the controllability of the product and the product quality; improve the production efficiency.

[0101] The above are only the preferred embodiments of the utility model and are not intended to limit the utility model. For those skilled in the art, the utility model can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
