[0003] The utility model with the publication number CN217373312U discloses a car glove box mold with a large slider and a built-in inclined top demoulding mechanism. The utility model comprises an injection lower mold and an injection upper mold, wherein the bottom of the injection upper mold is provided with a molding concave portion, and the injection lower mold is provided with a molding convex portion. During the injection molding process, the utility model brings the injection lower mold and the injection upper mold close to each other, so that the molding concave portion and the molding convex portion are abutted and matched to form a complete cavity, and the molten material is injected into the cavity through the injection molding part for injection molding.

DETAILED DESCRIPTION

[0032] The following is combined with Figure 1-6 The present application is further described in detail to make the technical solution of the present application easier to understand and grasp.

[0033] The embodiment of the present application discloses a side drawer mechanism for an injection mold of an inner chamber 41 of a glove box 4 .

[0034] Reference Figure 1-Figure 5The side-drawing mechanism of the glove box 4 inner cavity 41 of the present embodiment comprises a core plate 1 with a molding surface and a cavity plate 2, and also comprises a side-drawing mechanism 3 for the inner cavity 41. The side-drawing mechanism 3 for the inner cavity 41 is used for molding and demolding the inner cavity 41 of the glove box 4. The side-drawing mechanism 3 for the inner cavity 41 comprises a molding block 31 with a molding surface of the inner cavity 41 and a driving assembly 33. The molding block 31 is slidably connected to the core plate 1 along an inclined direction with the mold opening direction of the mold, and the molding block 31 is away from the molding. One end of the molding surface is fixedly connected to a limiting block 32, and the molding block 31 and the limiting block 32 are integrally formed. A slideway 11 is fixedly connected to the side of the core plate 1, and the limiting block 32 is slidably connected to the slideway 11. The two sides of the slideway 11 in the width direction are respectively fixedly connected to abutment blocks 12, and the abutment block 12 abuts against the limiting block 32 on one side of the slideway 11. Preferably, an accommodating cavity 21 is provided on the cavity plate 2, and when the mold is in a mold closing state, the accommodating cavity 21 wraps the molding block 31 inside. When the mold is closed, the molding block 31 is limited to reduce the possibility that the molding block 31 is not moved into place. The driving component 33 is used to drive the sliding of the limiting block 32. When the driving component 33 drives the limiting block 32 to slide to the extreme position toward one side of the core plate 1, the limiting block 32 abuts against the core plate 1, and the molding surface on the molding block 31 does not contact the core plate 1.

[0035] Reference Figure 1-Figure 5 , the driving assembly 33 drives the limit block 32 to slide, so that the molding block 31 fixedly connected thereto slides together. When the driving assembly 33 drives the limit block 32 to slide to the core plate 1 side to the limit position, the limit block 32 abuts against the core plate 1, and limits the sliding of the molding block 31, so that the molding surface of the molding block 31 does not contact the core plate 1, and the possibility of uneven wall thickness of the molded product is reduced; when the driving assembly 33 drives the limit block 32 to slide toward the side away from the core plate 1, the molding block 31 is separated from the inner bucket cavity 41 of the molded product, and the inner bucket cavity 41 is partially demolded, which reduces the moving stroke of the core plate 1 and the cavity plate 2, reduces the manufacturing cost of the mold, and speeds up the processing efficiency. By setting the slideway 11 and the abutment block 12, the sliding of the limit block 32 is limited, and the possibility of deviation in the sliding of the limit block 32 is reduced, thereby reducing the possibility of deviation in the movement of the molding block 31 and the possibility of uneven wall thickness of the molded product.

[0036] Reference Figure 1-Figure 4The driving assembly 33 includes a first cylinder 331 and a connecting rod 332. The first cylinder 331 is fixedly connected to the side of the slideway 11 away from the limit block 32. The connecting rod 332 is in an "L" shape. The longer end of the connecting rod 332 is fixedly connected to the limit block 32, and the shorter end of the connecting rod 332 is fixedly connected to the piston rod of the first cylinder 331. When the limit block 32 slides to the extreme position toward the core plate 1, the shorter end of the connecting rod 332 abuts against the side of the slideway 11 away from the core plate 1. The overall volume of the mold after mold closing is reduced, and the manufacturing cost of the mold is reduced; the piston movement of the piston rod of the first cylinder 331 drives the connecting rod 332 fixedly connected thereto to reciprocate, so that the limit block 32 and the forming block 31 and the connecting rod 332 reciprocate together. When the limit block 32 slides to the extreme position toward the core plate 1, the shorter end of the connecting rod 332 abuts against the slideway 11, limiting the sliding of the limit block 32, reducing the possibility of sliding deviation of the limit block 32 and the possibility of uneven wall thickness of the molded product.

[0037] Reference Figure 1-Figure 4 The limit block 32 is fixedly connected with an insert block 321, and the core plate 1 is provided with a slot 13 that is plugged and matched with the insert block 321. When the limit block 32 slides toward one side of the core plate 1 until it abuts against the core plate 1, the insert block 321 is plugged and matched with the slot 13. Through the plug-in cooperation between the insert block 321 and the slot 13, the sliding of the limit block 32 is limited, reducing the possibility of deviation in the sliding of the limit block 32 and reducing the possibility of uneven wall thickness of the molded product.

[0038] Reference Figure 1-Figure 5 The molding block 31 and the limiting block 32 are integrally formed, the molding block 31 is provided with a first cooling water channel 311, the limiting block 32 is provided with a water inlet channel 322 and a water outlet channel 323, respectively, and the first cooling water channel 311 is connected to the water inlet channel 322 and the water outlet channel 323. During the injection molding process, water enters through the water inlet channel 322, flows through the first cooling water channel 311, and then flows out from the water outlet channel 323, cooling the molding block 31, thereby accelerating the cooling time of the molded product and improving the processing efficiency.

[0039] Of course, the above are only typical examples of the present application. In addition, the present application may have many other specific implementation methods. All technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present application.
