Abstract

The utility model discloses a safe thermosetting plastic heating die. The safe thermosetting plastic heating die comprises an operating bench, an upper die, a lower die and a pedestal which are sequentially superposed from top to bottom, the upper die is arranged below the operating bench, the lower die is arranged on the pedestal, a plurality of heating tubes are arranged in the upper end portion of the upper die and in the lower end portion of the lower die, and the external surfaces of the upper die and the lower die are respectively provided with a heat insulation layer. The safe thermosetting plastic heating die can prevent an operating personnel from burning in the thermosetting plastic molding, and greatly improves the die safety.

Description

Safe heating solidity plastic heating mould

Technical field

The utility model relates to a kind of mould, relates in particular to a kind of safe heating solidity plastic heating mould.

Background technology

In the process of thermosetting plastics, the electrothermal tube that traditional material heat transfer form is generally by the workbench setting conducts heat first to mould, conduct heat to plastics by mould again, making it produce chemical reaction until solidify fully becomes primary product after the demoulding, by following process, become after the assay was approved product at last.This form of directly conducting heat with workbench; characteristics are that electrothermal tube fixing rear electrothermal tube in the workbench special hole needn't move; the location is protected not fragile relatively; but in diabatic process owing to be the step transmission; thermal losses is larger; power consumption is large, and the simultaneously variation along with climate change and air themperature also causes the heat endurance of mould relative relatively poor.

In order to address the above problem, following patented technology has been proposed in the prior art:

China Patent No. " 201220128365.9 " discloses a kind of for direct-fired mould, and its open day is on December 19th, 2012.Its technical scheme comprises stacked from top to bottom operating desk, die ontology and base for this mould; Die ontology comprises up and down symmetrically arranged upper die and lower die; Patrix is arranged on the below of operating desk, and counterdie is arranged on the top of base; Be respectively equipped with some heating tubes in the upper end of patrix and the bottom of counterdie, this heating tube successively horizontal parallel is arranged at intervals at the inside of the end portion of the upper part of patrix or counterdie, and heating tube is electrothermal tube; Between patrix and the operating desk, also be respectively equipped with one deck heat insulating mattress between counterdie and the base; Between the upper die and lower die for not being fixedly connected with; The length of side of operating desk and base is more than or equal to the length of side of die ontology corresponding sides; Die ontology is the metal pattern of heat conduction.

But the prior art take above-mentioned patent document as representative; in actual use; because the heating of electrothermal tube; cause the temperature of upper die and lower die outer surface also very high; and there is not protective device on the mould; to thermoset plastic forming the time, exist easy scald operating personnel's potential safety hazard, its security is low.

The utility model content

The purpose of this utility model is to solve the problems referred to above that the thermosetting plastics heating mould exists in the prior art, a kind of safe heating solidity plastic heating mould is provided, the utility model can prevent that operating personnel are burned, and have significantly improved the security of mould to thermoset plastic forming the time.

For achieving the above object, the technical solution adopted in the utility model is as follows:

A kind of safe heating solidity plastic heating mould, comprise from top to bottom stacked successively operating desk, upper die and lower die and base, patrix is arranged on the below of operating desk, counterdie is arranged on the top of base, be respectively arranged with some heating tubes in the upper end of patrix and in the bottom of counterdie, it is characterized in that: the outer surface of described upper die and lower die is provided with thermal insulation layer.

Described thermal insulation layer is connected with upper die and lower die are bonding.

The thickness of described thermal insulation layer is 0.5-1.5cm.

Employing the utility model has the advantage of:

One, in the utility model, owing to all be provided with thermal insulation layer at the outer surface of described upper die and lower die, therefore to thermoset plastic forming the time, operating personnel can operate mould relievedly, and do not worry and can be scalded by mould, have significantly improved the security of mould; Do not worry the scald problem owing to operating personnel again, so forming process is faster, higher to the efficient of plastic shaping; Thermal insulation layer makes the dissipation of heat on the upper die and lower die slower simultaneously, significantly saves energy consumption, thus reduced production cost.

Two, in the utility model, described thermal insulation layer is connected with upper die and lower die are bonding, and is simple in structure, installs fast, is easy to realize.

Three, in the utility model, the thickness of described thermal insulation layer is 0.5-1.5cm, the thickness of thermal insulation layer is less than 0.5cm, effect of heat insulation is poor, and the thickness of thermal insulation layer will cause cost to rise greater than 1.5cm, so the thickness of thermal insulation layer is set to 0.5-1.5cm, existing good effect of heat insulation makes again cost lower.

Description of drawings

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

Be labeled as among the figure: 1, operating desk, 2, thermal insulation layer, 3, base, 4, heating tube, 5, patrix, 6, handle, 7, counterdie, 8, heat insulating mattress.

The specific embodiment

A kind of safe heating solidity plastic heating mould, comprise from top to bottom stacked successively operating desk 1, patrix 5, counterdie 7 and base 3, patrix 5 is arranged on the below of operating desk 1, counterdie 7 is arranged on the top of base 3, be respectively arranged with some heating tubes 4 in the upper end of patrix 5 and in the bottom of counterdie 7, the outer surface of described patrix 5 and counterdie 7 is provided with thermal insulation layer 2.

Further, the thermal insulation layer 2 preferred porous heat insulation materials that use are made, such as foam heat insulating material, fibrous insulating material etc.

Preferred embodiment of the present utility model is that described thermal insulation layer 2 is connected bonding the connection with counterdie with patrix 5.

In the utility model, the thickness of described thermal insulation layer 2 can be 0.5cm, also can be 1.5cm, and the thickness of preferred described thermal insulation layer 2 is 1cm.

In the utility model, between described patrix 5 and the operating desk 1, be respectively equipped with one deck heat insulating mattress 8 between counterdie 7 and the base 3, operating desk 1 and the base 3 preferred heat insulation materials of insulation that adopt are made.

In the utility model, the both sides of described patrix 5 and counterdie 7 also are provided with handle 6, are convenient to carrying, place and the operation mould.
