[0023] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] Example 1, by Figure 1 The present invention relates to an injection molding mold for an interior cover, comprising a base 1, a lower mold 4 fixedly mounted on the top of the base 1, an upper mold 5 provided directly above the lower mold 4, the upper mold 5 being adapted to the lower mold 4, and a drip-proof mechanism 2 and a drive mechanism 3 provided on the top of the base 1.

[0025] Specifically, by Figure 2-3The anti-drip mechanism 2 includes a mounting plate 201 fixed to the top of the upper mold 5. The mounting plate 201 has a through hole 204 in its center. The upper mold 5 has an injection hole. A riser 205 is fixedly connected to the top of the upper mold 5, corresponding to the injection hole. The inner diameter of the injection hole is equal to the inner diameter of the riser 205. The riser 205 passes through the through hole 204. An injection tube 203 located above the mounting plate 201 is fixedly connected to the outside of the riser 205. A sealing plug 208 is movably installed inside the riser 205. An L-shaped rod 207 is fixedly connected to the top of the mounting plate 201. A sliding plate 206 is movably sleeved on the outside of the L-shaped rod 207. A connecting post 202 is fixedly connected to the outside of the sliding plate 206. The bottom end is fixedly connected to the sealing plug 208. The outer side of the L-shaped round rod 207 is fixedly sleeved with a bottom ring 209 and a top ring 2014. The bottom ring 209 is located below the top ring 2014. The sliding plate 206 is located between the bottom ring 209 and the top ring 2014, and the sliding plate 206 is in contact with the top ring 2014. The top of the mounting plate 201 is rotatably connected to a screw 2010. The top end of the screw 2010 is fixedly connected to a turntable 2013. The outer side of the screw 2010 is threaded with a threaded sleeve 2011. The sliding plate 206 is fixed to the outer side of the threaded sleeve 2011. The end of the L-shaped round rod 207 away from the mounting plate 201 is fixedly connected to a side block 2012. The screw 2010 passes through the side block 2012 and is rotatably connected to the side block 2012.

[0026] In the initial state, the top of the slide plate 206 abuts against the top ring 2014, while the sealing plug 208 is located above the connection between the injection tube 203 and the riser 205. At this time, the injection material can be injected between the upper mold 5 and the lower mold 4 through the injection tube 203, the riser 205, and the injection hole. After the injection material is injected, the turntable 2013 is rotated first, which drives the screw 2010 to rotate. Through the screw sleeve 2011, the slide plate 206 slides down along the L-shaped round rod 207. Then, through the connecting post 202, the sealing plug 208 slides inside the riser 205, scraping off the injection material adhering to the riser 205 and the inner wall of the injection hole. When the bottom of the slide plate 206 abuts against the bottom ring 209, the bottom surface of the sealing plug 208 is flush with the bottom surface of the injection hole, sealing the injection hole and preventing the injection material in the injection tube 203 from dripping continuously, thus preventing the formation of irregular deposits.

[0027] Specifically, by Figure 4-5 As shown, the drive mechanism 3 includes a top plate 301 located directly above the mounting plate 201. Two drive cylinders 304 are symmetrically fixed between the top plate 301 and the mounting plate 201. Two upright plates 302 are symmetrically fixed between the top plate 301 and the base 1. Side frames 303 are movably sleeved on the outer sides of the two upright plates 302. The mounting plate 201 is fixed between the two side frames 303. Multiple rollers 305 are provided at equal angles on the inner side of the side frames 303. Each roller 305 is in contact with the upright plate 302.

[0028] In use, the two drive cylinders 304 are first activated to move the mounting plate 201 and the upper mold 5. At the same time, the side frame 303 moves on the outside of the upright plate 302, and each roller 305 rolls on the upright plate 302 to limit the mounting plate 201 and ensure the stability of the mounting plate 201 and the upper mold 5 when they move. Finally, the mold closing and demolding are quickly achieved.
