[0002] Rotomolding, also known as rotational molding, rotational molding, rotational molding, etc., is a method of hollow molding of thermoplastic plastics through a mold, and the parting surface is the contact surface of the upper and lower molds of the rotational mold.

[0003] In the prior art, a Chinese patent document with authorization announcement number CN205767117U discloses a composite aluminum alloy rotational molding mold parting surface structure. This structure is achieved by lining the back of the original aluminum alloy mold parting surface with a heat-resistant steel pad. The heat-resistant steel pad is high-strength and not easy to deform, thereby eliminating or greatly reducing the deformation problem of the aluminum alloy mold parting surface and ensuring the quality of the rotationally molded product.

[0004] However, when the above solution is used, the parting surface is a plane, and both the upper and lower molds have working cavities. When the two upper and lower molds are connected, the position accuracy of the two working cavities cannot be guaranteed, resulting in defects in the rotationally molded products. In addition, adjusting the upper mold after placement will cause friction on the parting surface of the upper and lower molds. After long-term use, the sealing between the upper and lower molds will be reduced. Utility Model Content

[0036] The upper and lower parts of the limit assembly are respectively arranged on the parting surfaces of the upper mold 2 and the lower mold 1, and are arranged around the outside of the working cavity of the lower mold 1 and the upper mold 2 to limit the connection position of the parting surface of the lower mold 1 and the upper mold 2 when in use;

[0037] The upper and lower parts of the auxiliary component are respectively arranged on the parting surfaces of the upper mold 2 and the lower mold 1, and are located between the limit component and the outer edges of the parting surfaces of the lower mold 1 and the upper mold 2, so as to enhance the connection strength of the parting surfaces of the lower mold 1 and the upper mold 2 when in use;

[0038] There are two reinforcing components 3 , which are respectively wrapped around the outer sides of the lower mold 1 and the upper mold 2 to enhance the overall strength of the lower mold 1 and the upper mold 2 when in use.

[0039] In this embodiment, the two reinforcing components 3 are respectively wrapped around the outside of the lower mold 1 and the upper mold 2 to increase the structural strength of the lower mold 1 and the upper mold 2. In the process of the upper mold 2 covering the lower mold 1, the upper and lower parts of the limit component are connected and the position of the upper mold 2 is adjusted to align the working cavities of the upper mold 2 and the lower mold 1, thereby improving the connection accuracy between the lower mold 1 and the upper mold 2 and avoiding sliding between the lower mold 1 and the upper mold 2, which causes wear on the parting surface of the lower mold 1 and the upper mold 2. At the same time, the upper and lower parts of the auxiliary component are connected so that the upper and lower parts of the auxiliary component and the limit component simultaneously bear the force generated by the offset between the lower mold 1 and the upper mold 2, thereby reducing the force applied to the limit component and improving the service life of the limit component.

[0040] Example 2

[0041] like Figure 2-6 As shown, the present invention proposes a composite aluminum alloy rotational molding mold parting surface structure. Compared with the first embodiment, in this embodiment, the limiting assembly includes a mounting groove 4 and a mounting block 6;

[0042] The mounting block 6 is provided on the lower end surface of the upper mold 2 and is accommodated in the inner side of the mounting groove 4. The mounting groove 4 is provided on the upper end surface of the lower mold 1 and is annular in shape. The cross section of the mounting groove 4 is V-shaped so that the opening size of the mounting groove 4 is larger than the bottom end size of the mounting block 6 during installation, so that the mounting block 6 can be installed smoothly and quickly in the inner side of the mounting groove 4.

[0043] Example 3

[0044] like Figure 2-6 As shown, the present invention proposes a composite aluminum alloy rotational molding mold parting surface structure. Compared with the first embodiment, in this embodiment, the number of auxiliary components is multiple groups, and each group is composed of multiple reinforcement structures.

[0045] Among them, the reinforcement structure includes a connecting groove 5 and a connecting block 7; the connecting groove 5 is arranged on the parting surface of the lower mold 1 and is located on the outside of the limit assembly; the connecting block 7 is arranged on the parting surface of the upper mold 2. When the lower mold 1 and the upper mold 2 are installed in coordination, the connecting block 7 is accommodated on the inner side of the connecting groove 5 to enhance the strength of the limit assembly when in use.

[0046] It should be noted that the depth of the connecting groove 5 is smaller than the depth of the mounting groove 4, and the height of the connecting block 7 is smaller than the height of the mounting block 6, so that the connecting groove 5 and the connecting block 7 can be quickly and accurately connected through the cooperation of the mounting groove 4 and the mounting block 6 during installation.

[0047] Example 4

[0048] like Figure 7-8As shown, the present invention proposes a composite aluminum alloy rotational molding mold parting surface structure. Compared with the first embodiment, in this embodiment, the reinforcement component 3 includes a supporting member 31 and a force-bearing member 33;

[0049] The support member 31 is installed at the end of the mold and is made of transverse and longitudinal reinforcement ribs;

[0050] The force-bearing member 33 is installed on the top of the supporting member 31 and wrapped around the outside of the mold, and is made of vertical reinforcement ribs and annular reinforcement ribs.

[0051] In an optional embodiment, a plurality of fixing grooves are provided on the back of the parting surface of the lower mold 1 and the upper mold 2, and a plurality of fixing blocks 32 are provided on the top of the force-bearing member 33. When the lower mold 1 and the upper mold 2 are installed in coordination, the fixing blocks 32 are accommodated in the inner sides of the fixing grooves of the lower mold 1 and the upper mold 2. It should be noted that the shape of the fixing block 32 is cross-shaped and is used to provide support at multiple points on the back of the parting surface of the lower mold 1 and the upper mold 2 when in use, thereby improving the strength of the parting surface.

[0052] To sum up, when the present invention is in use, the supporting member 31 and the fixing block 32 are fixedly connected to the outer sides of the lower mold 1 and the upper mold 2 after assembly, and the fixing block 32 is embedded in the fixing grooves of the lower mold 1 and the upper mold 2, thereby increasing the structural strength of the parting surface of the lower mold 1 and the upper mold 2, and adding raw materials to the inner side of the lower mold 1, and the upper mold 2 is covered on the lower mold 1. During the covering process, the mounting block 6 moves toward the mounting groove 4, and the mounting block 6 is placed on the inner side of the mounting groove 4 through the cross-sectional shape of the mounting groove 4, and fits against the inner wall of the mounting groove 4, thereby limiting the position of the lower mold 1 and the upper mold 2, improving the processing accuracy of the product, avoiding misalignment of the connection, and improving the sealing degree after the lower mold 1 and the upper mold 2 are connected. At the same time, the lateral movement of the lower mold 1 and the upper mold 2 is blocked, and when the mounting block 6 is placed on the inner side of the mounting groove 4, the connecting block 7 moves toward the inner side of the connecting groove 5, so that the connecting block 7 is placed on the inner side of the connecting groove 5 and fits against the inner wall of the connecting groove 5, thereby improving the connection strength between the mounting groove 4 and the mounting block 6.
