Abstract
The utility model relates to a mould for processing crosslinking-reaction liquid materials. The mould comprises an upper half mould and a lower half mould that are connected together. Each half mould comprises a mould core (5) and a mould body (3). An injection mould cavity (4) is arranged between the mould core (5) and the mould body (3). A material admitting pipe is communicated with the injection mould cavity. The periphery of the integral mould body is provided with a corresponding casing (1), and a sealed cavity between the casing (1) and the mould body (3) is provided with a liquid medium heating channel (2) and a material preheating channel (6). The material preheating channel (6) is under the mould body (3). The material admitting pipe gets through the material preheating channel (6). A baffle board (7) is arranged between the liquid medium heating channel (2) and the material preheating channel (6). The mould has compact structure and is capable of saving energy and generating a minor internal molding pressure, which realizes better formation, and achieves injection models with better surface gloss and smaller inner stress.
Description
Technical field
The utility model relates to a kind of mould, particularly a kind of mould that is used to process the liquid material of cross-linking reaction.
Background technology
In the prior art, when fluid silicone rubber LSR, the RTV of processing cross-linking reaction or similar material, often producing undesirable pressure in mould again and again increases.Material at room temperature injects in the heated mold, because the unexpected rising of the temperature in the mould makes that material begins to expand, produces very high cavity pressure like this, makes the material that injects in the die cavity inhomogeneous, produces the bigger finished product of internal stress; By the various technology of material preheating, often cause many difficulties again, because material reacts, clean the effort difficulty in these devices, and the waste material.In addition in the prior art, the heating liquid medium channel is laid in outside the mould usually, with some flexible pipes with mould therewith passage couple together, make the entire die complex structure, and cause heat energy in flexible pipe, to scatter and disappear.
The utility model content
Technical problem of the present utility model is to overcome the deficiencies in the prior art part, and a kind of less cavity pressure, the mould of compact conformation are provided, can better moulding, obtain the injection moulded products of better surface gloss and littler internal stress.
The technical scheme that the utility model technical solution problem is adopted is: a kind of mould that is used to process the liquid material of cross-linking reaction, close up by two half modules up and down and to form, each half module comprises core and die body, it between core and the die body injection molding die cavity, material enters pipe and is communicated with the injection molding die cavity, it is characterized in that: be provided with the shell that correspondence is closed up in the whole periphery that closes up die body, be provided with the heating liquid medium channel in the enclosed cavity between shell and die body, the material preheating channel, described material preheating channel is below die body, material enters pipe and passes the material preheating channel, is provided with dividing plate between hot liquid medium passage and the material preheating channel.The preheating channel that the die body below is provided with makes material before entering die cavity, and even preheating gradually makes material be unlikely to unexpected expansion in die cavity, can not produce very high cavity pressure.
The utility model can also be achieved through the following technical solutions: respectively be provided with one group of heating liquid medium channel in the cavity between described each half module and the shell, the heating liquid medium channel is made up of two pipelines that are positioned at the die body upper and lower, each pipeline is provided with corresponding round, two of every correspondence rounds are communicated with through tube connector up and down, and the entrance of heating liquid medium channel is at a side, the pipe outlet opposite side above die body below the die body.The heating liquid passage places in the shell, makes the compact conformation of entire die, makes heat energy be difficult for scattering and disappearing, can energy savings.
The utility model can also be achieved through the following technical solutions: a dividing plate is arranged between preheating channel and the cavity, and this dividing plate is thermal insulation board or insulation board, is used for heat insulation between the die body of preheating channel and cavity and heating liquid medium channel.Because the temperature that needs in the die body die cavity is often unequal with the preheating channel temperature, and preheating channel necessity is to heat in advance, dividing plate is set can not transmit the heat in the preheating channel in the die body die cavity, avoid unnecessary temperature increase in the die body die cavity, heat in the preheating channel is difficult for scattering and disappearing simultaneously, saved heat energy, better material has been injected.Uniform distribution heater makes material obtain real-time preheating in the preheating channel.Preheating channel is provided with the liquid measure control valve with the die cavity place of connection, can better control the flow of liquid material.
The beneficial effects of the utility model are: The mould features compact structure described in the utility model, save heat energy, and easy to clean, can better moulding, and obtain the injection moulded products of better surface gloss and littler internal stress.
