Abstract

The utility model relates to a device which conducts the heating to a mould, wherein the outer part of the device is provided with a cover body and a heater is arranged in the cover body and is arranged on a bracket. The heater is composed of a plurality of burners and gas pipe lines communicated with the burners, a support block is arranged on the heater, a mould is arranged on the support block and is heated by the heater, thereby, the polyvinyl chloride can be further processed. Because the electric heating is replaced, the utility model can solve the heating problem of large-sized moulds, and can further produce various large-sized products of the polyvinyl chloride.

Description

The device that mould is heated

The utility model relates to a kind of heater, specifically relates to a kind of electrically heated device that mould is heated that replaces.

Along with market to maximization polychlorostyrene worker alkene product such as lamp ponds such as (PVC), and various decorations, as the demand of door and window, decorative thread, circummure, skirting etc., this maximization product makes mould to large scale development, and present electric heating equipment obviously can not adapt to the heat request that adds of this maximization mould, in addition, adopt Electric heating, not only energy resource consumption is big, but also must be at the heating of large mold, be equipped with temperature regulating device, make whole heater complexity, and use inconvenient.

The purpose of this utility model be to propose a kind of simple in structure, replace the device that mould is heated with electric heating equipment.

The purpose of this utility model is achieved in that cover body of outer setting, and the cover body top has steam vent, is used for scavenging, and is used for heat-insulation and heat-preservation simultaneously; One heater is arranged in the cover body, this heater is arranged on the support, this heater is made up of a plurality of burners and burning line, the number of burner is decided according to the size and the shape of mould, burning line is connected with burner, and burning line communicates with thermal source, and thermal source is with common combustion gas, as liquefied petroleum gas, town gas, natural gas etc.; Several back-up blocks are set on heater, mould is placed on the heater by back-up block, when needs during to mold heated, then open thermal source, combustion gas is sent in each burner along the burning line of heater, the ignition combustion device, thereby the mould on heater is heated, when being heated to the required temperature of plastic processing, should takes out by heated mould again, add pvc material by common mode, thereby be processed into polyvinyl chloride shaped article with a certain size and decorative pattern.

Adopt heater of the present utility model to solve the problem that large mold is heated, that can handle very skillfully processes various large-scale polyvinyl chloride decorative spares, this device structure is simple, and cost is low, and heating is fast, particularly not electricity consumption but heat with combustion gas, thereby saved electric consumption, owing to can increase the number of the burner of heater flexibly, therefore can the heating large mould, and homogeneous heating, thereby opened up a new road for the processing of large-scale polyvinyl chloride product.

The utility model is described in further detail with the form of embodiment below.

Fig. 1 is a structural representation of the present utility model.

As shown in Figure 1: this device is provided with support 2, is placed with heater 3 on it, is equipped with several back-up blocks 7 on the heater, and total covers in the cover body 1, and the cover body top has steam vent; Heater is by supporter 4, and burner 5 and fuel gas pipeline 6 are formed, and fuel gas pipeline 6 is seated in the supporter 4, and several burners 5 are housed on the pipeline.

During use, mould is placed on the back-up block 7, opens burnt gas switch, combustion gas enters in pipeline 6 and each burner 5, and the ignition combustion device is to mold heated, temperature can reach 120 ℃-200 ℃, actual temp depends on material to be processed, after mould reaches needed temperature, removes cover body 1, the mould taking-up is put on the other platform, add pvc material, melt-forming in mould, thus process various different products.
