Description
Technical field
The utility model is related to plastic foam processing technique field, more particularly, to a kind of mould for plastic foam shaping
Core.
Background technology
Plastic foam, is a kind of chemical material, full name polystyrene foam plastics, with light weight, firm, shock-absorbing, low suction
Tide, easy-formation and the low feature of good water resistance, thermal insulation, price, be widely used in packaging, insulation, waterproof, every
The fields such as heat, damping., it is necessary to the shape according to article is selected during using plastic foam, allow the article can be with plastic foam
Fit completely, so as to preferably play a part of to protect and support.When plastic foam is molded, a usually monoblock, so
Needs are cut according to its purposes, form given shape.Again because plastic foam is easily broken, so during cutting
Easily cause the damage of plastic foam.Therefore, in order to avoid it is above-mentioned the occurrence of, can be when plastic foam be molded, toward mould
The core rod with given shape is added in tool, is shaped for the inside to plastic foam, so as to allow the plastics of given shape
Foam is integrally formed, and reduces the situation that plastic foam is damaged by cutting, and can also improve processing efficiency.
But, because core rod is provided in inside mold, and because plastic foam can occur during shaping
The expansion of volume, so core rod can be caused tightly to be pressed together with plastic foam so that core rod is difficult to be taken from plastic foam
Go out.
Utility model content
The utility model is intended to provide a kind of core rod for plastic foam shaping, to solve the core rod of prior art offer
It is difficult to the problem taken out from plastic foam.
To achieve these goals, the utility model provide it is a kind of for plastic foam shaping core rod, including base and
It is fixedly connected on the stem of base upper end, the masking foil also including heat exchanger and the tubular being set in outside stem, masking foil
Top be fixedly connected with stem tip edge, the bottom of masking foil is fixedly connected with base upper end, between masking foil and stem
It is provided with and water is marked between condenser pipe, and masking foil and stem, be provided with refrigerant in condenser pipe, the liquid inlet of condenser pipe and goes out liquid
Mouth is respectively positioned on the lower end of base and is connected with heat exchanger, and through hole is additionally provided with base, and the upper end of through hole is located at masking foil and core
Between post, through hole is provided with valve.
The know-why of the technical program and have the technical effect that：For the core rod of plastic foam shaping, including base and core
Post, stem is fixed on base, constitutes core rod., it is necessary to constantly be passed through high temperature during due to being molded in plastic foam
Steam, so the technical program is arranged with masking foil outside stem, for avoiding the stem in masking foil from being burnt out by high temperature.The bottom of at
Seat is provided with the through hole between masking foil and stem, for injecting water into the space between masking foil and stem, by tinfoil paper
Paper is separated with stem, it is to avoid masking foil is extruded and offseted with stem by plastic foam so that plastic foam is difficult to the demoulding.
Due to masking foil soft material, and water has mobility, so masking foil is easily because of the extruding of plastic foam
Deformation, so as to the shape for causing the plastic foam after shaping changes.Therefore, in order to avoid it is above-mentioned the occurrence of, in tin
The condenser pipe with refrigerant is provided between foil paper and stem, allows water that ice is frozen into the presence of refrigerant, so as to be tinfoil paper
Paper provides stronger supporting role.Condenser pipe is also connected with outside heat exchanger, and the refrigerant allowed after absorption heat can be
Heat is released at heat exchanger, and is again introduced into condenser pipe, so circulation, so as to avoid the ice sheet between masking foil and stem
Melt, cause the deformation of masking foil.
The core rod that this programme is provided is mainly used in the shaping of the plastic foam with through hole, the height of the plastic foam after shaping
Height of the degree less than stem.So, toward after injecting water between masking foil and stem, water surface elevation is needed more than moulding plastics foam
Height, after allowing water to be frozen into ice, support can be provided to the forming process of the whole through hole of plastic foam.
After plastic foam shaping, stop the cooling to ice sheet, allow ice sheet to be melted into water, and allow water to be flowed out from through hole.It
Afterwards, using air-extractor, extract the air between masking foil and stem out, allow masking foil to be shunk to stem in the presence of pressure,
So that there is certain space between masking foil and plastic foam, so as to core rod easily can be taken from plastic foam
Go out, reduce the difficulty of plastic foam processing.
The following is the preferred scheme of such scheme：
Preferred scheme one：Based on base case, cavity is provided with the stem, heat riser is provided with cavity.Work as plastics
After foam-formed, heat riser can be opened, accelerate the speed that ice sheet melts, so as to improve the processing efficiency of plastic foam.
Preferred scheme two：Based on preferred scheme one, the condenser pipe in the shape of a spiral, is set in outside stem, can increase water
With the contact area of condenser pipe so that condensation effect is more preferable.Additionally, during plastic foam is molded, near masking foil
Ice sheet be easy to melt, so condenser pipe is set into curl, the ice sheet of thawing can be reduced, and then preferably ensure modeling
The shape of strand foam.
Preferred scheme three：Based on preferred scheme two, junction and masking foil and the base of the masking foil and stem
Junction is equipped with fluid sealant.Fluid sealant can avoid water from being spilt from the junction of masking foil and stem or base soaking foaming
Material, additionally it is possible to ensure that the water between masking foil and stem will not change, so as to preferably maintain the shape of masking foil.
Preferred scheme four：Based on base case, the volume of the water between the masking foil and stem is less than masking foil and core
Volume between post.Volume can become big when being frozen into ice due to water, thus allow water volume less than space volume, energy
The situation that masking foil is bursting at the collision caused by water coagulated volume becomes greatly is enough avoided to occur.
Preferred scheme five：Based on preferred scheme four, the distance between the masking foil and stem are 5mm.If ice sheet is too
Thickness, just poorly controlled by condenser pipe so that outmost ice-out faster, so as to influence the shaping of plastic foam；Such as
Fruit ice layer is too thin, and plastic foam will be made to be frozen near the part of ice sheet, is also unfavorable for shaping.
