Description
Technical field
The invention belongs to shock isolating pedestal technical field of mold, more particularly, to a kind of one-piece type shock isolating pedestal mold.
Background technique
Shock isolating pedestal refers to that structure is the supporting arrangement for reaching shock insulation requirement and being arranged, and is between superstructure and ground
Increase Seismic Isolation of Isolation Layer, rubber earthquake isolation support is installed, play and be flexible coupling with ground, technology in this way can earthquake 80%
The energy offset of left and right falls.Shock isolating pedestal be optimized integration shock insulation critical elements and basic construction material, in highlight lines
Have on earthquake region and Important building Aseismic Design and has been widely used.
The basic structure of shock isolating pedestal is one layer of sheet rubber by design requirement, and one layer of steel disc is alternately superimposed, through sulphur
Change machine and mold cooperation, carrying out vulcanizing treatment makes rubber and steel disc form one, and becoming a kind of has huge vertical supporting ability
With the shock-insulation building material of soft horizontal deformation.
It is pressed into lead for retractable pencil at the center of shock isolating pedestal, constitutes lead core rubber support.Melting after lead for retractable pencil indentation with rubber support is one
Body is followed shear-deformable, and this support is the resistance that the energy absorbing device for the restoring means and lead stabilized by rubber support is constituted
The one-piece type earthquake isolating equipment of Buddhist nun mechanism.Lead is a kind of metal with good plastic deformation ability and energy absorption capability.Lead for retractable pencil
Rubber support is also one of the support for being used for isolation structure earliest.Lead core rubber support relies on its excellent mechanical property, more
Simple construction and high performance-price ratio, are widely applied in engineering.
Existing shock isolating pedestal mold, can only realize simple function mostly, for example, processing rubber piece is one set of die, it will
It is one set of die that sheet rubber and steel disc, which are layering, and it is one set of die that lead for retractable pencil, which is pressed into rubber support,.Complete product is produced,
Die cost is high.Every mold will have matched machine or a machine frequently more mold exchange, product processes process
Too long, process is tedious, time-consuming and laborious, high labor cost, is unfavorable for promoting and applying.
Existing shock isolating pedestal production technology is to heat sulfurizing mould at suitable pressures with vulcanizing press, to shock insulation
Support is vulcanized.The path of heat transfer has three, first is that from top to bottom, second is that from bottom to top, third is that surrounding heat, feature
It is serial.On serial heat-transfer path from top to bottom, from bottom to top, since film and the steel disc of shock isolating pedestal are mutually superimposed
Structure there are the sheet rubbers of high thermal resistance, hinder the conduction of heat, increase heating time.
Equally, especially there is being pressure in the path of surrounding heating because there are certain gaps between shock isolating pedestal and mold
In the case where, sizing material overflows around when heating vulcanizes, and forms glue diaphragm between support and mold, also counteracts mold to support
Heating.
Although can properly increase curing temperature to improve heating efficiency, the heat transfer lag of rubber can still be led
Non-uniform heat transmitting is caused, the over cure phenomenon in hot-spot place and the undervulcanization phenomenon in local overcooling place is formed, influences
Shock isolating pedestal quality.Especially large-scale shock isolating pedestal is even more increased and is evenly heated and due to the increase of area, lamination quantity
The difficulty of even vulcanization.The central part of shock isolating pedestal is often undervulcanization, and marginal portion then over cure the phenomenon that it is prominent, influence to produce
Quality.

When upper mold 1 and lower die 3 are heated using vulcanizing equipment, to be preheated to mold, after preheating, by sizing material by pouring
Geat 13 injects in outer middle mould die cavity 44, and the sizing material that upper mold 1, lower die 3 and middle mould 2 continue in externally in mould die cavity 44 is added
Heat, to shorten vulcanization duration.
Using this Mold Making lead for retractable pencil and shock isolating pedestal pressing when, need to take out mandrel 8, by lead for retractable pencil indentation be
It can.
The advantages and positive effects of the present invention are:
1, the present invention provides a kind of one-piece type shock isolating pedestal molds, when interior middle mould and outer middle mould are integrated in use, by steel
The punching of plate layer is placed in interior middle mould die cavity, cooperates mandrel, upper die and lower die, can be real by being poured rubber in inside middle mould die cavity
The pressing layer by layer of existing rubber layer and steel plate layer；Mould in outer is opened, interior middle mould is removed, is locked in outer after mould, it is outside by sprue gate
Casting rubber in middle mould die cavity is, it can be achieved that the lamination of the covering on rubber layer and steel plate layer cylindrical surface is closed；Upper mold is opened, mandrel is taken out,
The indentation of lead for retractable pencil can be achieved；By one set of die, each process is combined together, it is time saving and energy saving, reduce the branch of die cost
Out, have a wide range of application.
2, the present invention is passed through in the heating oil pocket formed inside outer middle mould by that will heat oil, while being set with the use of vulcanization
It is standby that upper die and lower die are heated, outer middle mould jointly heats sizing material with upper die and lower die.It can guarantee glue
Material sulfidation is uniformly heated, and multi-faceted heating is carried out to sizing material, the upper and lower state of cure (vulcanization) is avoided the occurrence of and is higher than
The phenomenon that middle layer, effectively raises product quality.And mold preheating can significantly be shortened by comprehensive heating
Time effectively raises the production efficiency of shock isolating pedestal so that sizing material is quickly vulcanized, and reduces production cost.
3, the present invention sets separate structure for outer middle mould by attachment device and locking device, realizes opening for outer middle mould
Close, while attachment device is set as detachable structure, it is convenient in mould installation and removal, can be in the feelings of human body not contact product
Under condition, product stripping is completed, it is highly-safe, it is practical.
4, the present invention is by the cooperation of the first limiting device and the second limiting device, can effective fixation steel plate layer, can basis
The rubber layer thickness requirement of actual product, adjusts the gap length between the steel plate layer of placement as required, realizes that different size produces
The production of product, has a wide range of application, the first limiting device activity setting, practical convenient for the disengaging of mandrel and product.
5, the present invention can make outer middle mold have more stable work by the way that independent seed oil road is arranged inside each outer middle mould
Make state, when middle mould is passed through heating oil outside, each seed oil road independent can carry out preheating to mold or carry out to sizing material
Heating will not interact between seed oil road, prevent from causing what entire oil circuit can not be connected to show since a certain seed oil road blocks
As, while also avoiding heating oil and being leaked in oil circuit, guarantee the stabilization of heating process.
Mode the above is only the implementation of the present invention is not intended to limit the scope of the invention, all to utilize this
Equivalent structure or equivalent flow shift made by description of the invention and accompanying drawing content, it is relevant to be applied directly or indirectly in other
Technical field is included within the scope of the present invention.
