[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-3A molding device for an automotive panel includes a cooling water tank 1, a protective shell 3 on the upper surface of the cooling water tank 1, a lower mold 4 on the upper end of the protective shell 3, multiple sets of columns 5 fixedly connected to the upper surface of the lower mold 4, a top plate 6 fixedly connected to the upper end of the multiple sets of columns 5, a first cylinder 7 on the upper surface of the top plate 6, the telescopic end of the first cylinder 7 penetrating the top plate 6 and fixedly connected to a mounting plate 8, a detachable upper mold 9 on the lower surface of the mounting plate 8, a model groove 10 for fitting the upper mold on the upper surface of the lower mold 4, an ejection mechanism 13 for ejecting the automotive panel at the bottom of the model groove 10, a water inlet chamber 41 and a water return chamber 43 inside the lower mold 4, multiple water inlet chambers 42 between the water inlet chamber 41 and the water return chamber 43, the multiple water inlet chambers 42 being equidistantly arranged, and a circulating water guiding mechanism 2 for cooling the lower mold 4 on one side of the cooling water tank 1.

[0022] The above design utilizes a circulating water guiding mechanism to facilitate the flow of cooling water into the water inlet chamber 41 and water distribution chamber 42 of the lower mold 4, thereby uniformly cooling the injection-molded automotive panel, improving the cooling efficiency of the automotive panel, and thus improving the molding efficiency of the automotive panel.

[0023] Specifically, the circulating water guiding mechanism 2 includes a water pump 21 located on one side of the cooling water tank 1. The inlet end of the water pump 21 is connected to the cooling water tank 1, and the outlet end of the water pump 21 is provided with an inlet pipe 22 connected to the inlet chamber 41. The other side of the cooling water tank 1 is provided with an outlet pipe 23 connected to the return chamber 43. This design utilizes the water pump 21 to guide the cooling water from the cooling water tank 1 into the inlet chamber 41. Under the guidance of the multi-component water chamber 42, the efficiency of the cooling water passing through the water distribution chamber 42 is accelerated, thereby allowing the cooling water to return to the cooling water tank 1 via the outlet pipe 23 after passing through the return chamber 43. This achieves the recycling of cooling water and improves the cooling efficiency of the molded automotive panel.

[0024] Specifically, hook plates 15, which penetrate the lower mold 4, are fixedly connected to both ends of the lower surface of the mounting plate 8. The hook plates 15 are L-shaped, and guide blocks 14, located between the two sets of hook plates 15, are fixedly connected to the lower surface of the lower mold 4. This design allows for easy adjustment of the position of the ejection mechanism 13 via the guide blocks 14, facilitating the separation of the ejection mechanism 13 from the hook plates 15 and thus improving practicality for subsequent ejection of the automotive panel.

[0025] Specifically, the ejection mechanism 13 includes a base plate 131. Two sets of top beams 132 are slidably mounted on the lower surface of the base plate 131. The lower ends of both sets of top beams 132 penetrate the lower mold 4 and are fixedly connected to a cone block 133 that is slidably mounted with the guide block 14. The distance between opposite sides of the two sets of cone blocks 133 is greater than the distance between opposite sides of the two sets of hook plates 15. This design allows the cone blocks 133 to rise via the hook plates 15, thereby causing the top beams 132 to lift the base plate 131, facilitating the ejection of the cooled car panel and improving the efficiency of removing the car panel. Simultaneously, the two sets of top beams 132 driving the base plate 131 to rise and fall improves the stability of the base plate 131, thus ensuring the quality of the car panel.

[0026] Specifically, the ejection mechanism 13 also includes a fixing block 134. Telescopic sleeves 135 are fixedly connected to both sides of the fixing block 134. Springs 136 are fitted onto the outer sides of both sets of telescopic sleeves 135. One end of each set of telescopic sleeves 135 relative to the fixing block 134 is slidably disposed with one side of each set of top beams 132. This design limits the springs 136 by the telescopic sleeves 135, causing the cone block 133 to contact the guide block 14, which in turn compresses the springs 136 on the top beam 132. This facilitates the disengagement of the cone block 133 from the hook plate 15, allowing the ejection mechanism 13 to reset under gravity.

[0027] Specifically, the lower mold 4 has guide holes 44 inside for mounting two sets of top beams 132 and fixing blocks 134. The guide holes 44 are H-shaped. A carrier plate 12 is provided on one side of the lower mold 4, and an ejection mechanism 11 is provided on the other side of the lower mold 4. The above design allows the carrier plate 12 to conveniently support the removed car panel.

[0028] Specifically, the ejection mechanism 11 includes a corner plate 111, and a second cylinder 112 is provided on one side of the corner plate 111. The telescopic end of the second cylinder 112 passes through the corner plate 111 and is fixedly connected to a push plate 113. This design allows the cylinder to drive the push plate 113 to push the ejected car panel, thus facilitating the movement of the car panel onto the carrier plate 12, making it easier to remove the car panel and improving the safety of removing it.

[0029] In use, the controller controls the extension end of the first cylinder 7 to extend, thereby embedding the upper mold into the mold groove 10. Injection is then performed through the injection hole of the upper mold, filling the mold groove 10 with injection material. After the car panel is formed, the controller controls the water pump 21 to pump cooling water from the cooling water tank 1 into the inlet chamber 41. Under the action of the multi-component water chamber 42, the water flows into the return water chamber 43. As the cooling water passes through the water distribution chamber 42, the water flow velocity increases, thereby improving the heat exchange efficiency of the car panel in the lower mold 4, thus improving the cooling effect of the car panel and accelerating the forming speed of the car panel. After forming, the extension end of the first cylinder 7 retracts, causing the hook plate 15 to drive the cone block 133, which in turn causes the top beam 132 to lift the bottom plate 131. The base plate 131 lifts the car panel to the surface of the lower mold 4. Under the action of the two sets of top beams 132, the stability of the lifting and lowering of the base plate 131 is improved. The second cylinder 112 is activated to push the push plate 113 into the carrier plate 12, which facilitates the removal of the molded car panel and improves the safety of removing the car panel. When the next car panel is being injected, the extension end of the first cylinder 7 is fully reset, and the hook plate 15 drives the cone block 133 to continue to rise, so that the cone block 133 abuts against the guide block 14. Under the action of the guide block 14, the top beam 132 compresses the spring 136 on the telescopic sleeve 135, so that the cone block 133 disengages from the hook plate 15. Then, under the action of gravity, the base plate 131 falls back to the bottom of the mold groove 10, which improves practicality.
