Embodiment Construction

[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings and examples. The following examples are explanations of the present invention and the present invention is not limited to the following examples.

[0028] see Figure 1-Figure 3 , this embodiment includes a support frame 1, a console, a rotating system, a heating system, a cooling system and a mold 2.

[0029] The support frame 1 is a convex platform with an isosceles trapezoidal cross-section composed of twelve support rods, and its internal space is in a hollow state. The rotating system is fixed on the upper end surface of the trapezoidal convex platform, and the rotating system can obtain enough space when rotating. to rotate.

[0030] There is a control system on the console, which is directly connected with the rotation system, heating system and cooling system respectively, and the operator only needs to directly interact with the control system to cont...

Abstract

The invention relates to a comprehensive and efficient rotational molding platform, and belongs to the technical field of thermoplasticity forming. The comprehensive and efficient rotational molding platform comprises a supporting frame and further comprises a control table, a rotating system, a heating system, a cooling system and a mold, wherein the rotating system, the heating system, the cooling system and the mold are connected with the control table. The rotating system comprises a plurality of rotating devices diffident in size, the rotating devices are sequentially and fixedly mounted in a loop form according to the relative sizes, and each rotating device can achieve 360-degree autoroatation. The rotating system is fixed to the supporting frame in an autoroatation manner. The mold is fixed in the rotating system in an autoroatation manner. The heating system is fixed to the mold. The cooling system is fixed to the rotating device closest to the mold. The rotating system of the comprehensive and efficient rotational molding platform comprises the multiple rotating devices, each rotating device can achieve 360-degree autoroatation, the mold is driven to rotate spherically, the situation that a mold of an original rotational molding machine can rotate in a single direction is directly broken through, and the rotational molding efficiency of the rotational molding platform and the product quality are directly improved; heating is carried out directly, constant temperature is achieved, no open flame exists, and safety is achieved; and the rotational molding process is easy to control and operate.

Description

technical field [0001] The invention relates to a comprehensive and high-efficiency rotational molding platform, which belongs to the technical field of thermoplastic molding. Background technique [0002] Rotational molding machine is a commonly used plastic product molding machine, especially for large closed or semi-closed products with low precision requirements, this method is often used for molding. It generally uses the principle of spherical trajectory thermoplastic molding, adding quantitative powder into the rotating mold cavity, heating the mold through the heat source, and at the same time making the heated mold rotate along the spherical trajectory, the plastic melts and plasticizes, adheres to the entire surface of the mold cavity and cools and shapes, and finally Open the mold and take out the product. [0003] For example, the Chinese Patent No. CN2190551Y (Application No. 93241002.2) discloses "a dual-arm rotational molding device", which includes a heating...
