Description
Technical field
The utility model is related to injection mold field, and in particular to a kind of injection mold.
Background technology
Plastic product is widely used in our daily lifes, and plastic product is made up of mold injection or blowing.Note
Mould is a kind of instrument for producing plasthetics；Also it is to confer to the instrument of plasthetics complete structure and accurate dimension.Injection
Shaping is to produce a kind of processing method used during some complex-shaped parts in batches.The material by heated thawing is referred specifically to by height
Injection enters die cavity, after cooling and solidifying, obtains formed products.
In daily life a kind of common housing packaging be use plastic casing and flat board with accommodating chamber fit into
Row encapsulation, and plastic casing is generally transparent thin-wall construction, and accommodating chamber is traditionally arranged to be curved indentations, is that more preferable protection is treated
Packing article surface, curved indentations can also be set to shiny surface, and must have higher essence for the plastic casing encapsulated
Degree can ensure that article to be packaged does not loosen after packaging, and required precision is higher, and because plastic casing is used to encapsulate, it is molded matter
Amount also needs to be protected.Such product is in injection because the mold insert of lower mould is smooth surface, and product wall thickness is too low, causes note
Mold insert is easily separated from during plastic point mould and sticks to upper mold core, takes out difficult, and mold insert is arranged at into upper mould can then cause mould difficult
To eject, thimble or the easy crushing moulding of jacking block are set, production needs mold insert to possess harsh roughness requirements, very not
Just, and maintenance difficult, the injection of shiny surface is also required to carry out injection strict temperature control, existing injection mold temperature
Regulation and control are not excessively gentle, normally only mould cooled by the way of water cooling, temperature control is poor, also have some using heating
Device carries out heating treatment to mould, so as to accelerate temperature adjusting efficiency, mould is reached predetermined temperature as early as possible, repeatedly temperature difference mistake
It is big to be easily damaged upper mold core and lower mold core, regular processing especially is needed to the shiny surface of mold insert, large batch of production is not suitable with,
Therefore it is difficult to simply solve problems in existing mould.
Utility model content
The utility model purpose is to provide a kind of injection mold, and it can efficiently solve asking in the presence of background technology
Topic.
Technical problem to be solved in the utility model is realized using following technical scheme：
A kind of injection mold, including the upper mould and lower mould that set gradually up and down, the upper mould are embedded with upper mold core, it is described under
Mould is embedded with lower mold core, and the lower mould is provided with guide rod and stretched into mould, and the upper mold core is provided with the die cavity of curved surface, it is described under
Mould is provided with least one mold insert and stretches into die cavity, and the mold insert moulding section is axially arranged inside curved protrusion, the mold insert
There is air cavity, the mold insert length direction is provided with least one air guide inserted block and extended in air cavity；Axially opened inside the mold insert
Provided with warm water displacement slot, the upper mold core is provided with water-cooling channel and steam channel respectively around die cavity, and the lower mold core is set
It is equipped with the water-cooling channel and steam channel respectively around mold insert.
Utility model works principle is as follows：
Air cavity can connect any existing getter device by any connected mode during injection, after the completion of moulding injection
Starting getter device makes air cavity formation vacuum state, and due to there is gap between air guide inserted block and mold insert, air cavity can be inhaled by gap
Gas therein is walked so as to produce absorption affinity to moulding, air guide plug-in unit more at most absorption affinity is stronger, and the size in gap makes
Principle can not pass through, it is ensured that the quality of production, mould can be divided to handle after starting getter device, ensure that moulding will not be adhered to
Upper mould, and the smoothness of curved protrusion can be improved, make and require reduction, repair more convenient.Upper mold core and lower mold core point
Not She Zhi water-cooling channel cooling treatment is carried out to mould, upper mold core and lower mold core also set steam channel to be rapidly heated respectively
Processing, and smooth surface is arranged in the curved protrusion of mold insert, sets warm water displacement slot to be carried out by warm water to mold insert on mold insert
Temperature buffer is adjusted, and optimizes the injection effect of moulding smooth surface, it is to avoid excessive temperature differentials influence smooth surface is molded effect repeatedly.
Further, the lower mould is additionally provided with push pedal, and the air guide inserted block, which is extended in push pedal and fixed with push pedal, to be connected
Connect.
Push pedal is set to promote air guide inserted block by push pedal, so as to eject moulding.
Further, the water-cooling channel is provided with water cooling entrance and water cooling outlet extends respectively to mold exterior.Water cooling
Entrance and water cooling outlet can connect any existing cold water water supplying machine.
Further, the steam channel is provided with steam inlet and steam (vapor) outlet extends respectively to mold exterior.Steam
Entrance and steam (vapor) outlet can connect any existing steam air feeder.
The beneficial effects of the utility model are：
The utility model is simple in construction, the problem of adhering to mould when efficiently solving moulding point mould, production stability
Good, efficiency high, Product Precision can be ensured very well, and gentle stable regulation and control have been carried out to mould, so as to ensure
The quality of product shiny surface injection.
