Problems solved by technology

The above two secondary feeding methods mainly have the following problems: 1. During the feeding process, the temperature of the outer surface of the mold is above 200°C, that is, it is in a high temperature state. The feeding process is manually operated, so there are obviously high operational risks and high production efficiency. low problem
2. For rotomolded products with limited secondary feeding space, the existing technology cannot complete the secondary feeding during the product molding process

Embodiment 1

[0031] like Figure 1 to Figure 4 As shown, the rotational molding secondary feeding device 11 includes a secondary feeding storage bin 1 and a discharge control mechanism.

[0032] The secondary feeding storage bin 1 has a material storage inner cavity 1a, and the secondary feeding storage bin 1 is used for temporarily storing the raw materials to be added into the cavity 10a for the second time, referred to as secondary feeding for short. The secondary feeding storage bin 1 includes a storage body 1b and a cover 1c capable of sealing the upper port of the storage body 1b, the storage body 1b and the cover 1c are connected by a detachable structure; add two When adding materials for the next time, open the lid 1c, and close the lid 1c after the addition is completed. The material storage body 1b is in the shape of a funnel so that the material outlet corresponds to the secondary feeding port, and at the same time, all the secondary material to be added can automatically fall...

Embodiment 2

[0040] The structure and principle of this embodiment are basically the same as that of Embodiment 1, and the basic similarities will not be redundantly described, and only the differences will be described, and the differences are as follows: Figure 5 As shown, the outer edge of the cover 1c is the first connecting sleeve 12 made of bakelite, the inner plate 1e and the outer plate 1d of the cover 1c are made of steel plates, and the inner plate 1e and the outer plate 1d of the cover 1c are all made of The first connecting sleeve 12 is fixedly connected. The edge portion 1g of the storage body 1b is a second connecting sleeve 13 made of bakelite material, and the first connecting sleeve 12 and the second connecting sleeve 13 are connected by threads. The top surface of the second connecting sleeve 13 abuts against the bottom surface of the first connecting sleeve 12 . In order to improve the sealing performance, a sealing ring 14 is provided on the top surface of the mouth p...

Abstract

The invention provides a rotational molding secondary feeding device and a rotational molding die, which belong to the technical field of plastic processing and aim at solving the problem that an existing secondary feeding mode is high in operation risk and low in production efficiency. The rotational molding secondary feeding device comprises a secondary feeding storage cabin, wherein the cabin wall of the secondary feeding storage cabin is provided with a heat insulation structure; the secondary feeding storage cabin comprises a hopper-shaped storage body and a cover capable of covering an upper end opening of the storage body; the storage body is connected with the cover through a detachable structure; the storage body is provided with a discharge control mechanism which is used for enabling a nozzle part of a hopper of the storage body to be at a communicated or cutoff state. According to the rotational molding secondary feeding device provided by the invention, the structure of the cabin wall of the secondary feeding storage cabin is firm and applicable to acting as a connecting basic part between the secondary feeding device and the die; the cabin wall has a good heat insulation effect, and thus the characteristic change of materials to be fed for the second time in the secondary feeding storage cabin due to high temperature affect is avoided.

Description

technical field [0001] The invention belongs to the technical field of plastic processing, and relates to rotational molding, in particular to a secondary feeding device for rotational molding. [0002] The invention belongs to the technical field of plastic processing, and relates to a rotational molding, in particular to a rotational molding mold. Background technique [0003] Rotational molding is a hollow molding method for thermoplastics. The method is to add plastic raw materials into the mold first, then the mold is continuously rotated along two vertical axes and heated, and the plastic raw materials in the mold are gradually and evenly coated and melted and adhered to the cavity under the action of gravity and heat energy. On the entire surface, it is formed into the desired shape, and then cooled and shaped to form a product. [0004] With the development of rotomolding technology, the range of application of its products is continuously expanding. Some represent...
