Description

Technical Field

[0001] The utility model relates to an injection mold, in particular to a slider-linked turnover box injection mold. Background Art

[0002] Turnover crates are typically injection molded using an injection mold. To facilitate mold opening, side slides are used on the sides of the crate, and guide mechanisms for these slides are therefore incorporated into the mold. Because turnover crates are typically both deep and wide, conventional horizontal injection molding machines, due to limited space, have significant limitations on the width and depth of the crates they can produce to accommodate the guide mechanisms. Utility Model Content

[0003] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a slider-linked turnover box injection mold.

[0004] The technical solution adopted by the utility model to solve its technical problems is: a slider-linked turnover box injection mold, comprising a front mold base, a rear mold base, a rear mold core arranged on the front side of the rear mold base, and a front mold core arranged on the rear side of the front mold base, wherein the front mold base is provided with four side slides that slide along the vertical plane, and the side slides are assembled with the front mold core and the rear mold core to form a mold cavity after the mold is closed, and pushing parts are connected between the side slides on the left and right sides and the front mold base, that is, the pushing parts push the side slides toward the rear mold base, and guide strips are provided at the upper and lower ends of the side slides on the left and right sides, and guide grooves are provided at the left and right ends of the side slides on the upper and lower sides for cooperating with the guide strips, and a guide column extending obliquely backward is provided on the front mold base, and the guide column extends from the center of the front mold core toward the outer side of the rear mold base, and the side slide is provided with a guide sleeve for cooperating with the guide column.

[0005] As a further improvement of this design, the pushing member is an oil cylinder or a pneumatic cylinder.

[0006] As a further improvement of the present design, each of the side sliders is provided with at least two groups of guide sleeves, and each group of guide sleeves is composed of guide sleeves located at the front and rear sides of the side slider respectively.

[0007] As a further improvement of the present design, a fixed block is provided on the front side of the front mold base, and two adjacent guide columns on adjacent side sliding blocks are connected to the same fixed block.

[0008] As a further improvement of the present design, the angle between the joint surface between adjacent side sliding blocks and the horizontal plane is 90°, and the extension path of the guide groove is perpendicular to the joint surface between adjacent side sliding blocks.

[0009] As a further improvement of the present design, the cross section of the guide groove is U-shaped.

[0010] As a further improvement of the present design, a connecting block connected to the pushing member is provided on the front mold base, and the connecting block and the pushing member are connected via a T-slot structure.

[0011] The beneficial effect of the present invention is that the present invention realizes the opening and closing of the four side sliders only through the pushing pieces on both sides through the guide strips and the guide grooves matched with the guide strips provided on the side sliders, thereby reducing the mechanism and reducing the restrictions on the width and depth of the turnover box production.

[0018] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. The exemplary embodiments and descriptions are only used to explain the present invention but are not intended to limit the present invention.

[0019] Example: See Figure 1 and Figure 2, a slider-linked turnover box injection mold, comprising a front mold base 1, a rear mold base 9, a rear mold core 10 arranged on the front side of the rear mold base 9, and a front mold core 7 arranged on the rear side of the front mold base 1. The front mold base 1 is provided with four side sliders 8 that slide along the vertical plane. After the mold is closed, the side sliders 8 are assembled with the front mold core 7 and the rear mold core 10 to form a mold cavity. A pushing piece 5 is connected between the side sliders 8 on the left and right sides and the front mold base 1, that is, the pushing piece 5 pushes the side sliders 8 toward the rear mold base 9. The side sliders 8 on the left and right sides are provided with guide strips 2 at the upper and lower ends, and the side sliders 8 on the upper and lower sides are provided with guide grooves 6 that cooperate with the guide strips 2 at the left and right ends. A guide column 4 extending obliquely to the rear is provided on the front mold base 1. The guide column 4 extends from the center of the front mold core 7 to the outer side of the rear mold base 9, and the side slider 8 is provided with a guide sleeve 3 that cooperates with the guide column 4.

[0020] The guide bars 2 provided on the side sliders 8 and the guide grooves 6 cooperating with the guide bars 2 only require the push members 5 on both sides to realize the opening and closing of the four side sliders 8, thereby reducing the mechanism and reducing the restrictions on the width and depth of the turnover box production.

[0021] See Figure 1 In order to further simplify the structure, the pushing member 5 adopts an oil cylinder or an air cylinder.

[0022] See Figure 1 In order to improve the guiding stability of the guide column 4 on the side slider 8 while reducing the friction between the guide column 4 and the guide sleeve 3. Each side slider 8 is provided with at least two sets of guide sleeves 3, and each set of guide sleeves 3 is composed of guide sleeves 3 located on the front and rear sides of the side slider 8.

[0023] See Figure 4 In order to improve the stability of the connection between the guide column 4 and the front mold base 1 and simplify the structure, a fixed block 12 is provided on the front side of the front mold base 1, and two adjacent guide columns 4 on adjacent side sliders 8 are connected to the same fixed block 12.

[0024] See Figure 1 In order to facilitate the movement of the side sliders 8 and reduce the friction between the guide strips 2 and the guide grooves 6, the angle between the joint surfaces of the adjacent side sliders 8 and the horizontal plane is 90 degrees, and the extension path of the guide grooves 6 is perpendicular to the joint surfaces between the adjacent side sliders 8.

[0025] See Figure 1 In order to prevent the guide bar 2 from getting stuck with the guide groove 6, the cross section of the guide groove 6 is U-shaped.

[0026] See Figure 3The front mold base 1 is provided with a connecting block 11 connected to the pushing member 5. The connecting block 11 is connected to the pushing member 5 through a T-slot 13 structure, which is used to compensate for the horizontal position difference between the pushing member 5 and the front mold base 1, and also facilitates the connection between the pushing member 5 and the front mold base 1.

Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
