Description

Technical Field

[0001] This utility model relates to the field of underbody protection plate processing technology, specifically to an engine underbody protection plate forming device that facilitates quick mold replacement. Background Technology

[0002] Existing automotive chassis typically have underbody protection plates installed to protect the engine. These plates are usually made of fiberglass, which is lightweight and high-strength. During the molding process of a fiberglass engine underbody protection plate, the fiberglass needs to be pressed between upper and lower molds using a molding device to form the plate. Traditionally, the molds are fixed to the pressing plate in the molding device using bolts. This means that when changing the mold, multiple bolts must be removed one by one, and then installed again afterward, resulting in significant manpower and time expenditure for mold replacement.

[0003] Patent publication number CN220841598U discloses an engine underbody protection plate forming device, including a pressing plate. The top of the pressing plate is equipped with a hydraulic device for driving the pressing plate, and the bottom of the pressing plate is equipped with an upper mold for making the underbody protection plate. Symmetrical connecting components for connecting the pressing plate are arranged on both sides of the upper mold. A lower mold matching the upper mold is located at the bottom of the upper mold, and a base for mounting the lower mold is located at the bottom of the lower mold. This invention utilizes the design of the pressing plate, base, upper mold, lower mold, insert block, mounting block, and connecting components. By pressing the locking block, it enters the mounting groove, allowing the insert block to move out of the mounting groove for quick replacement of the upper mold. When replacing the lower mold, the fixing rod is pulled out, and the mounting block drives the lower mold to slide out of the rectangular groove for replacement. No bolt disassembly or installation is required, making mold replacement more convenient and saving time and manpower. However, some defects were found in the actual use of the above-mentioned device: First, the upper mold is locked in place by a locking block, and the lower mold is replaced and installed by sliding. However, the pressing plate generates a large impact force during the molding process, which poses a risk of the upper mold falling off and the lower mold shaking during pressing, affecting the quality of the fiberglass engine underbody protection plate after molding. Second, the upper mold needs to be replaced by a hydraulic device to assist in disassembly and installation, which is cumbersome and inefficient. Third, the lower mold needs to be replaced to ensure that the mounting holes at the bottom of the lower mold are aligned with the fixing rod, which requires installation and positioning, affecting the replacement efficiency. Utility Model Content

The guide pillars 2 are used for guidance during pressing and forming to ensure the quality of pressing and forming.

[0022] The lower mold 6 is provided with two side baffles 8 on its left and right sides. Both side baffles 8 are arranged in the front-back direction. The two side baffles 8 are provided with locking components that are connected to the lower mold 6. The upper mold 7 is fitted with the pressing plate 4. The pressing plate 4 is provided with connecting components that are connected to the upper mold 7.

[0023] As a further improvement to this embodiment, the locking assembly includes a plurality of through holes 9 disposed on two side stops 8, a plurality of locking holes 10 disposed on the left and right sides of the lower mold 6 and matching the number, position, and size of the plurality of through holes 9, and a plurality of locking rods 11 passing through the plurality of through holes 9 and engaging with the plurality of locking holes 10. A side plate 12 is fixedly connected to the outer rod portion of the plurality of locking rods 11 on the same side. In this embodiment, the number of the through holes 9, locking holes 10, and locking rods 11 is six, with three distributed on each side.

Furthermore, two limiting slots 14 are provided at the upper ends of the left and right sides of the lower mold 6, and the shape of the limiting slots 14 matches the contour of the pull handles 13. The limiting slot 14 is used to limit the locking assembly in the horizontal direction after the locking assembly locks the lower mold 6, so as to prevent the locking assembly from loosening due to impact force during the pressing and molding of the fiberglass engine bottom guard plate.

[0024] As a further improvement to this embodiment, the mounting plate 3 is provided with four positioning blocks 15 distributed around its perimeter, and the bottom of the lower mold 6 is provided with four positioning grooves 16 that match the position and size of the four positioning blocks 15. The positioning blocks 15 and the positioning grooves 16 ensure rapid positioning of the lower mold 6 before locking, and also prevent the lower mold 6 from shaking due to impact during the pressing and molding process.

[0025] When replacing the lower mold 6, place the lower mold 6 between the two side retaining strips 8 and make the positioning groove 16 engage with the positioning block 15 accordingly; then, insert the locking rod 11 through the through hole 9 into the locking hole 10 from both the left and right sides, so that the side plate 12 fits against the side wall of the side retaining strip 8, and then flip the pull handle 13 inward into the limit slot 14. At this time, the state is as follows. Figure 1 As shown.

[0026] As a further improvement to this embodiment, the pressing plate 4 is provided with four engaging through holes 17 distributed around its perimeter, and the top of the upper mold 7 is provided with four engaging inserts 18 that match the four engaging through holes 17 in terms of position and size. The engaging through holes 17 and engaging inserts 18 ensure rapid positioning of the upper mold 7 before connection.

[0027] Furthermore, each of the four engaging through holes 17 through which the four engaging rods 18 pass is provided with a lateral through-hole 19.

[0028] As a further improvement of this embodiment, the connecting assembly includes two rotating rods 20 disposed on the left and right sides of the pressing plate 4, and two gears 21 coaxially mounted on the two rotating rods 20. Each gear 21 is interlocked with two racks 22. The four racks 22 are slidably arranged in the front-back direction. The other ends of the four racks 22 are connected to four connecting through holes 19.

[0029] When replacing and installing the upper mold 7, first pass the engaging insert rod 18 through the engaging through hole 17 until the upper mold 7 is attached to the bottom of the pressing plate 4. Then, rotate the rotating rod 20 from both sides, and through the gear 21, drive the two racks 22 on the same side to move in opposite directions, so that their ends are inserted into the connecting through hole 19 on the body of the engaging insert rod 18. The state at this time is as follows: Figure 1 As shown.

[0030] This invention, through the aforementioned structure, enables rapid replacement of the lower and upper molds, improving replacement efficiency compared to existing technologies. By changing the connection method, this invention avoids the problems of the upper mold falling off and the lower mold shaking, ensuring the molding quality of the fiberglass engine underbody protection plate.
