Description
Technical field
The present invention relates to a kind of PU handrails foaming mould more particularly to a kind of PU handrails double swing doors foaming de-bubble moulds
Tool.
Background technology
Polyurethane material is the current best thermal insulation material of performance in the world.Main chain is containing-NHCOO-constitutional repeating unit
A kind of polymer, english abbreviation PU.It is polymerized with hydroxy compounds by isocyanates (monomer).Due to containing highly polar ammonia
Carbamate base does not dissolve in non-polar group, has good oil resistivity, toughness, wearability, resistance to ag(e)ing and adhesiveness.With
The material for adapting to wide temperature range (- 50~150 DEG C), including elastomer, thermoplastic resin and thermosetting can be made in different material
Property resin.Not hydrolysis under high temperature, also not alkali-proof medium.
Foamed plastics is one of principal item of polyurethane synthetic material, it is mainly characterized by porosity, thus opposite
Density is small, is changed according to raw material difference used and formula, it is several to can be made into soft, semi-rigid and rigid polyurethane foam etc.
Kind；If polyester-type, polyether-type and castor oil type polyurethane foamed plastics etc. can be divided into again by polyalcohol assortment used；If
Classifying again by foaming method has the types such as blocky, molding and spraying polyurethane foam plastic.
Polyurethane foam plastics application range is very extensive, almost penetrates into each department of national economy, especially in furniture, bed
The departments such as tool, transport, refrigeration, building, thermal insulation use very universal, it has also become one of indispensable material.As plastics
Most wide one of the kind of middle application range.Soft polyurethane foam is mainly used in furniture, bed accessory and other household wares, such as sofa and seat
Chair, backing cushion, mattress and pillow；Hard polyurethane foam is mainly used for adiabatic heat-insulation, refrigerating equipment and freezer, heat-insulating plate,
Wall thermal insulating, pipe insulation, the thermal insulation of storage tank, monocomponent bubble pointing etc..
The PU handrails mold of single open-door structure in the prior art is in use, it is not easy to spray releasing agent, also not
Facilitate taking-up product, therefore, it is urgent to provide a kind of new PU handrail molds.
Invention content
In order to overcome the deficiencies of the prior art, the object of the present invention is to provide a kind of PU handrails double swing doors foaming de-bubble moulds
Tool.
In order to solve the technical problem in background technology, the present invention provides a kind of foaming de-bubbles of PU handrails double swing doors
Mold, including upper die and lower die and intermediate mass, the upper mold rotate axis connection with the lower die by mould bases, and the intermediate mass is set
It being placed between the upper mold and the lower die, the intermediate mass is connect by shaft with the lower die, and there are two the intermediate mass,
The cavity of the lower die is obliquely installed.
Further, two intermediate mass are juxtaposed between the upper mold and the lower die.
Further, two intermediate mass are symmetrical arranged relative to the central axis of lower die.
Further, the straight line where the mould bases rotary shaft and the straight line where the shaft are orthogonal.
Further, the axes of rotation skew is set to the lower die both sides.
Further, there are two identical cavities for the lower die tool.
The beneficial effects of the invention are as follows：
(1) PU handrail double swing doors of the invention foaming de-bubble mold, double swing doors are easier than single open-door structure
PU handrail products are taken out, production operation is facilitated；
(2) PU handrail double swing doors of the invention foaming de-bubble mold, drag cavity dumping are arranged, and are produced in patternmaking process
Raw bubble all rises to product top, reduces influence of the bubble to entire product, to improve product quality；
(3) PU handrail double swing doors of the invention foaming de-bubble mold, double swing doors are more convenient the sprinkling of releasing agent,
Prepare production next time convenient for quickly cleaning mold, improves work efficiency.

Specific implementation mode
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art obtained under the premise of not making creative work it is all its
His embodiment, shall fall within the protection scope of the present invention.
Embodiment 1：
Please refer to Fig.1-5.As shown in Figs. 1-5, the invention discloses a kind of PU handrails double swing doors foam de-bubble mold,
Including upper mold 1, lower die 2 and intermediate mass 3, the upper mold 1 is connect with the lower die 2 by mould bases rotary shaft 4, the intermediate mass 3
It is set between the upper mold 1 and the lower die 2, the intermediate mass 3 is connect by shaft 5 with the lower die 2, the intermediate mass
There are two 3, the cavity of the lower die 2 is obliquely installed.
Continue as shown, two intermediate mass 3 are juxtaposed between the upper mold 1 and the lower die 2, two institutes
The central axis that intermediate mass 3 is stated relative to lower die 2 is symmetrical arranged, the straight line where the mould bases rotary shaft 4 and 5 institute of the shaft
Straight line it is orthogonal, the shaft 5 is obliquely installed in 2 both sides of the lower die, and there are two identical types for the tool of the lower die 2
Chamber.
When die sinking, by upper mold 1 with mould bases rotary shaft 4 for 90 degree of axle center Unscrew, two intermediate mass 3 are respectively with shaft 5
For 100 degree of axle center Unscrew, the PU handrail products in 2 cavity of lower die are then taken out, finally clear up die joint, spray releasing agent
