[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0015] Reference Figure 1-4 The shaping fixture for automotive interior PU lightweight sponge includes a shaping fixture 1, which includes a lower mold 11. The lower mold 11 has a mold cavity, and an auxiliary mold assembly 2 is vertically slidably arranged in the mold cavity. A connecting piece 4 is provided at the bottom of the auxiliary mold assembly 2. A cavity is provided in the lower mold 11 below the mold cavity, and an electric telescopic rod body 3 is arranged in the cavity. The top extension end of the electric telescopic rod body 3 is vertically upward, and a connecting ring 31 is rotatably installed on the top extension end of the electric telescopic rod body 3 through a bearing assembly. The connecting ring 31 is screwed to the connecting piece 4. The auxiliary mold assembly 2 includes a base plate 21 and a mounting frame 24. L-shaped positioning plates 22 are vertically fixedly installed at the four corners of the top of the base plate 21. Side plates 25 are fixedly installed at the bottom of the mounting frame 24 between two adjacent L-shaped positioning plates 22. The mounting frame 24 and the corresponding L-shaped positioning plates 22 are connected by a limiting component.
[0016] The outer wall of the connector 4 is provided with an external thread, and the top of the connecting ring 31 is provided with an installation groove for the connector 4 to be installed at the connector 4. An internal thread is provided in the installation groove at the external thread, and the internal thread is threadedly connected to the external thread.
[0017] The limiting component includes a screw body with a nut screwed to the top of the screw body. The mounting frame 24 has a clearance hole for the screw body to pass through at the screw body, and the top of the mounting frame 24 has a pick-up groove at the corresponding clearance hole.
[0018] Limiting plates 23 are fixedly installed at the top of the base plate 21 and between two adjacent L-shaped positioning plates 22, and a slot for inserting the limiting plate is provided on one side of the side plate at the limiting plate.
[0019] Multiple positioning rods are installed at equal intervals within the slot, and positioning grooves are provided on one side of the limiting plate 23 at the corresponding positioning rods. Sealing components are provided on both sides and the bottom of the side plate 25.
[0020] It is worth noting that the shaping fixture includes a base, on which a mounting frame is mounted, and on which a hydraulic rod assembly is mounted. The output end of the hydraulic rod assembly is vertically downward and connected to an upper mold. The upper mold is located directly above the lower mold. The shaping fixture is used to shape the sponge. The specific structure and working principle of the shaping fixture are all existing technologies that are currently publicly available on the market, so they will not be described in detail.
[0021] In this embodiment, holding the mounting frame 24, align the slot at the bottom of the side plate 25 with the limiting plate 23 on the base plate 21 and insert it downwards so that the positioning rod is inserted into the positioning groove, and align the clearance hole on it with the screw body on the L-shaped positioning plate 22 and insert it until it is fully inserted, so that the bottom of the mounting frame 24 fits against the L-shaped positioning plate 22 and is tightened with a nut. When the nut is tightened, the top surface of the nut is flush with the top surface of the mounting frame 24, and the mounting frame 24, side plate 25 and base plate 21 are firmly locked into an integral auxiliary mold assembly 2.
[0022] Open the electric telescopic rod body, extend its top end, and thread the connecting ring to the connecting piece at the bottom of the assembled auxiliary mold assembly 2. Then, control the closing of the electric telescopic rod body, retract the top end, and drive the assembled auxiliary mold assembly 2 into the mold cavity of the lower mold 11.
[0023] Next, the sponge can be shaped using a shaping fixture. After the shaping is complete and the mold has cooled, the electric telescopic rod body is opened. The top end of the electric telescopic rod body extends out and pushes the auxiliary mold assembly 2 and the shaped sponge out of the mold cavity. Then, the sponge can be demolded.
[0024] Then, after using it for a period of time, the auxiliary mold assembly 2 that has been ejected can be manually rotated. Then, the nuts can be loosened by screwing them on one by one. After removing the nuts, hold the mounting frame away from the base plate and move it away until it is separated from the base plate and the L-shaped positioning plate. Then the auxiliary mold assembly can be disassembled, cleaned, maintained or replaced.
[0025] In this invention, a detachable auxiliary mold assembly is provided in the mold cavity of the lower mold, which facilitates the quick disassembly of the auxiliary mold assembly after the sponge shaping fixture has been used for a period of time, so as to carry out the cleaning and maintenance of the positioning fixture in stages.
