[0021] Please see Figure 1-5This utility model provides an embodiment of an injection mold for a high-gloss automotive exterior trim part, comprising a support base 1 and a support cover 2. The support cover 2 is located on one side of the top of the support base 1, and the front of the support cover 2 has an opening. A double-opening baffle plate 13 is located on the front of the support cover 2 corresponding to the opening. A lower mold 3 is located in the middle of the top of the support base 1, and a mold groove is located in the middle of the top of the lower mold 3. A mold block 5 is engaged in the mold groove of the lower mold 3. L-shaped slots are located on both sides of the top of the lower mold 3 near the middle of the mold block 5, and L-shaped inserts 4 are located on both sides of the mold block 5 corresponding to the L-shaped slots. Both sides of the mold block 5 are connected by inserts... Block 1 4 is inserted into the slot of the lower mold 3. Threaded holes are provided on both sides of the lower mold 3 and at the corresponding middle positions of the insertion block 1 4. Screw 1 6 is threadedly connected to the threaded holes of both the lower mold 3 and the insertion block 1 4. Slots are provided on the top of the lower mold 3 at the middle positions of the front and back of the mold block 5. Slot 22 is provided on the mold block 5 at the corresponding slot positions. Slot 22 is provided on the mold block 5. Slot 22 is engaged with the slot of the lower mold 3 through slot 22. Threaded holes are provided at the corresponding middle positions of the lower mold 3 and slot 22. Screw 23 is threadedly connected to the threaded holes of both the lower mold 3 and slot 22. Nuts are threadedly connected to both ends of screw 23.

[0022] When in use, mold block 5 can be placed in mold groove, and then the insert block 4 and the clip block 22 around it can be inserted or clipped into the lower mold 3. Then, use screw 6 to fix insert block 4 to the lower mold 3, and then use screw 23 to screw through clip block 22 and the lower mold 3, and use nuts to screw at both ends to fix it. This can make mold block 5 more firmly installed, and facilitate its assembly and disassembly, and replace different molds for pressing.

[0023] The top of the support base 1 has a slot corresponding to the position of the baffle plate 13, and a motor 18 is located in the middle of the front of the support base 1. The output end of the motor 18 extends through the bearing to the support base 1 and a gear 17 is provided. The top and bottom of the gear 17 are provided with opposing L-shaped toothed strips 16, and the L-shaped toothed strips 16 mesh with the gear 17. The top of the L-shaped toothed strips 16 are connected to the bottom of the corresponding baffle plate 13 through the slot.

[0024] When in use, the motor 18 can be started to drive the gear 17 on its shaft to rotate. The gear 17 drives the L-shaped toothed strip 16 that meshes with it to move, so that the L-shaped toothed strip 16 at the top and bottom can move relative to each other. This can move the top baffle 13 to block the opening of the support cover 2, which can reduce the exhaust gas during injection molding. It can also move to expose the opening after injection molding, so that workers do not need to directly pull open the baffle 13 and thus avoid being burned by the temperature of the baffle 13.

[0025] Hydraulic cylinders 10 are provided at the middle positions on both sides of the top of the support cover 2, and the output ends of the hydraulic cylinders 10 extend into the support cover 2 and are fixedly connected to the lower pressure block 11, and the lower pressure block 11 has a slot at the middle position.

[0026] When in use, the hydraulic cylinder 10 can drive the lower pressure block 11 to rise and fall, which facilitates injection molding.

[0027] The bottom of the lower pressure block 11 is provided with an upper mold 12, and the middle position of the upper mold 12 is provided with an injection tube connected to the outer injection tube. The middle position of the top of the upper mold 12 is provided with a second insert block 19, and the upper mold 12 is inserted into the slot of the lower pressure block 11 through the second insert block 19. Heating blocks 21 are evenly provided around the inner perimeter of the second insert block 19, and the lower pressure block 11 around the second insert block 19 is provided with a slot. The top perimeter of the second insert block 19 is hinged with a first locking block 20 at the corresponding slot position. The first locking block 20 is engaged with the slot of the lower pressure block 11, and the middle position of the first locking block 20 is connected to the lower pressure block 11 by a fixing bolt.

[0028] When in use, the insert block 2 19 on the top of the upper mold 12 can be inserted into the slot, and then the hinged locking block 1 20 can be lowered and locked into the slot. It can be fixed to the lower pressure block 11 with fixing bolts, which makes it easy to assemble and disassemble the upper mold 12 and also easy to replace. Then, the heating block 21 can be activated to heat it as needed. It can heat the inner injection tube to prevent the injection liquid from cooling and solidifying inside the injection tube, which would affect the subsequent injection effect.

[0029] A telescopic rod 7 is provided in the middle of one side of the support cover 2, and the output end of the telescopic rod 7 extends into the support cover 2 to provide a receiving frame 8. The bottom of the receiving frame 8 is provided with an air suction block 9, and one end of the air suction block 9 is provided with a telescopic air suction pipe that extends to the outside and connects to the air suction box.

[0030] When in use, the telescopic rod 7 can move the receiving frame 8 and the suction block 9 to the bottom of the injection tube. The receiving frame 8 can collect the residual dripping liquid in the pipe, and the suction block 9 can suck the hot air emitted by the workpiece into the external suction box through the suction pipe. This can prevent the exhaust gas from being discharged directly and can also accelerate the cooling of the workpiece.

[0031] The top of each of the baffle plates 13 is provided with a slide bar 15, and the support cover 2 on the top of the slide bar 15 is provided with a groove 14, and the groove 14 is slidably connected to the slide bar 15.

[0032] When in use, the movement of the baffle 13 can cause the slide bar 15 to move within the slide groove 14, making the movement of the baffle 13 smoother.

[0033] In this embodiment, the mold block 5 is placed in the mold slot, and then the four insert blocks 4 and the two locking blocks 22 are inserted or locked into the lower mold 3. The insert blocks 4 are fixed to the lower mold 3 using screw 6, and the screw 23 is screwed through the locking blocks 22 and the lower mold 3, and the nuts are screwed on both ends to fix it, making the mold block 5 more secure. Then, the insert block 29 on the top of the upper mold 12 is inserted into the slot, and the hinged locking block 20 is lowered and locked into the slot. It is fixed to the lower pressure block 11 using fixing bolts, which facilitates the assembly and disassembly of the mold block 5 and the upper mold 12, and allows for the replacement of different molds for molding. After the mold is assembled, the motor 18 can be started to drive the gear 17 on its shaft to rotate. The gear 17 drives the L-shaped toothed strip 16 that meshes with it to move, which allows the L-shaped toothed strip 16 at the top and bottom to move relative to each other. This can move the top baffle 13 to block the opening of the support cover 2, which can reduce the exhaust gas during injection molding. The discharge of fluids is facilitated by the movement of the baffle plate 13, which in turn moves the slide bar 15 within the slide groove 14, allowing the baffle plate 13 to move more smoothly. Then, the hydraulic cylinder 10 can drive the lower pressure block 11 to rise and fall, facilitating injection molding. During injection molding of the workpiece, the suction block 9 can absorb the exhaust gas from the support cover 2, reducing the discharge of exhaust gas. After the workpiece injection is completed and separated, the telescopic rod 7 can move the receiving frame 8 and the suction block 9 to below the injection pipe, allowing the receiving frame 8 to collect any residual dripping liquid from the pipe. The suction block 9 draws the hot air emitted by the workpiece into the external suction box through the suction pipe, preventing the exhaust gas from being directly discharged and accelerating the cooling of the workpiece. When the workpiece needs to be removed, the baffle 13 can be moved to expose the opening, eliminating the need for workers to directly pull open the baffle 13 and thus avoid being burned by its temperature. When cleaning is required, the heating block 21 can be activated to heat the inner injection tube, preventing the injection liquid from cooling and solidifying inside the injection tube, which would affect the subsequent injection effect.
