Abstract

The utility model discloses a polyurethane foaming mold, which comprises an upper mold and a lower mold, wherein heating pipes are arranged on metal mold shells of the upper mold and the lower mold; and insulating layers for covering the mold shells and the surfaces of the heating pipes are sprayed on the upper mold and the lower mold, and are polyurethane insulating layers. During mold foaming, the polyurethane insulating layers can play a role in preserving heat of the mold shells and the heating pipes, direct contact with the air is eliminated, radiating is effectively reduced, temperature raising time is reduced, and energy is saved.

Description

A kind of polyurethane foam mould

Technical field

The utility model belongs to foaming mould, is specifically related to a kind of polyurethane foam mould.

Background technology

As shown in Figure 1, polyurethane foam mould 1 comprises upper and

lower mould

2,3, all be furnished with heating tube 4 on the metal formwork of upper and

lower mould

2,3, when polyurethane molding foams, mould 1 need be warming up to about 60 ℃, because the outer surface of mould 1 and heating tube 4 is all exposed, can directly contact with cold air, rapid heat dissipation makes that the mould heating-up time is longer, causes energy consumption very big.

The utility model content

Technical problem to be solved in the utility model provides a kind of polyurethane foam mould, can play insulation effect, to reduce the mould heating-up time.

In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:

A kind of polyurethane foam mould comprises upper and lower mould, all is furnished with heating tube on the metal formwork of upper and lower mould, it is characterized in that: be coated with the heat-insulation layer with formwork and heating tube surface coverage on upper and lower mould.

Described heat-insulation layer is a polyurethane insulation coating.

Adopt technique scheme, this polyurethane foam mould comprises upper and lower mould, all is furnished with heating tube on the metal formwork of upper and lower mould, is coated with the polyurethane insulation coating with formwork and heating tube surface coverage on upper and lower mould.When molded foaming, can play insulation effect to mould and heating tube by polyurethane insulation coating, eliminate directly contacting with air, effectively reduce heat radiation, reduce the heating-up time, thereby played energy-conservation effect. ?

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is elaborated:

Fig. 1 is the cutaway view of the polyurethane foam mould of prior art;

Fig. 2 is the cutaway view of polyurethane foam mould of the present utility model.

Among the figure: 1-polyurethane foam mould, 2-patrix, 3-counterdie, 4-heating tube, 5-polyurethane insulation coating. ?

The specific embodiment

As shown in Figure 2, polyurethane foam mould 1 of the present utility model equally also comprises upper and

lower mould

2,3, all is furnished with heating tube 4 on the metal formwork of upper and lower mould 2,3.Different is to be coated with the polyurethane insulation coating 5 with formwork and heating tube 4 surface coverage on upper and

lower mould

2,3, in order to mould 1 and heating tube 4 are played insulation effect, eliminate and directly contact with air, effectively reduce heat radiation, reduced the heating-up time, thereby play energy-conservation effect.This polyurethane insulation coating 5 can adopt commercially available wall thermal insulating spraying equipment directly to carry out the spraying polyurethane material and form.

After testing, behind the spray coating heat preservation material, 1 heating-up time of mould can reduce 20 minutes (when making an appointment with using electricity wisely 5kw., in the time of per hour can saving 2.2kw. in the normal productive process (is example with 1 die heater).If with 15 die heaters, every day full line to produce 10 hours be example, but every day during energy efficient=15*(5+10*2.2)=405kw. then, and the moon * 26(of the * 0.6(unit of benefit=405(kw)/kw) working day)=6318 yuan, effect is very considerable.

But; those skilled in the art will recognize that; the above-mentioned specific embodiment is exemplary; be in order better to make those skilled in the art can understand this patent; can not be interpreted as it is restriction to this patent protection domain; so long as according to spirit that this patent discloses done anyly be equal to change or modify, all fall into the scope of this patent protection.

Claims

1. a polyurethane foam mould comprises upper and lower mould, all is furnished with heating tube on the metal formwork of upper and lower mould, it is characterized in that: be coated with the heat-insulation layer with formwork and heating tube surface coverage on upper and lower mould.

2. polyurethane foam mould according to claim 1 is characterized in that: described heat-insulation layer is a polyurethane insulation coating.
