Problems solved by technology

[0006] However, the existing rotomolding equipment all use air as the heat conductor, that is, the heat source transmits heat to the mold hull through the air, so that the energy loss is large, the temperature is not suitable for control, and it is easy to reduce the quality of the product; at the same time, this heat transfer The method also makes the product limited by the volume of the hot box, which reduces the application range of the product

Embodiment Construction

[0022] The equipment of the present invention and the method for producing rotationally molded products will be described in detail below in conjunction with the accompanying drawings.

[0023] Such as image 3 As shown, the rotomolding mold of the present invention comprises a mold lower mold 1 and an upper mold 6, and the upper and lower molds respectively have a lower mold flange ring 2 and an upper mold flange ring 9, and the flange ring is provided with mold clamps 14. The upper mold bracket 7 is connected to the support frame 5 through a hinge, so that the upper mold can be opened; the outer surface of the lower mold 1 is covered with a hot oil heating pipeline 3 and a cooling pipeline 4. In order to increase and maintain the strength and shape of the lower mold 1, Lower die is arranged on a support frame 5, upper die 6 is fixed with upper die support 7, and the support frame of lower die is connected on the rotating support 8, and rotating support 8 can provide 360 ​​de...

Abstract

The invention relates to a rotational molding mould device and a method for manufacturing a rotational molding mould and relates to the technical field of rotational molding. The device comprises upper and lower modules capable of being opened and closed, wherein a flange ring is used for sealing; the lower module is connected to a rotary bracket; and a hot oil heating pipeline and a cooling pipeline are covered outside of the lower module. The method comprises the following steps: coating de-molding agent, and then feeding materials, sealing and rotating while heating with hot oil, and after finishing the steps, using the cooling pipeline to quickly cool and de-mould. The rotational molding mould device and the method for manufacturing a rotational molding mould have the advantages that the hot oil can conduct heat, the efficiency is high, the energy is saved, and different from the traditional devices, the device is free from being limited by the volume of a heating box, the hot oil is supplied by a hot oil furnace, the temperature control is reliable and stable, and the quality of products is increased.

Description

technical field [0001] The invention relates to a mechanical device, in particular to a rolling mold manufacturing device. Background technique [0002] Rotational mold is a normal pressure mold with the same shape as the product, thin and uniform wall. The traditional production method of the mold is to use ordinary low-carbon steel plates or aluminum plates to make spliced ​​parts by hand or stamping, and then complete the assembly process by welding. Rotational molding molds are suitable for the production of small batches and multi-variety products. The disadvantages of this production method are long production period, high production cost, low dimensional accuracy and high production labor intensity. [0003] At present, domestic rotomolding equipment is mainly divided into direct fire heating type and hot box hot air circulation heating type (hot box heating type) according to different heating methods. The direct fire heating type is currently generally used for r...
