Abstract
The utility model discloses a pressurize injection mold, its technical scheme main points are including movable mould, cover half, be equipped with the mouth of moulding plastics on the cover half, be equipped with the runner on the movable mould, the mouth of moulding plastics communicates with each other with the runner, be equipped with the die cavity on the movable mould, the runner communicates with each other with the die cavity, be equipped with the ejector sleeve on the cover half, sliding connection has the push rod in the ejector sleeve, push rod one end can be contradicted on the oral -lateral wall of moulding plastics, after the compound die finishes, the injection molding machine is moulded plastics in to the mouth of moulding plastics, the plastics of molten condition are in proper order through moulding plastics the mouth, the runner reachs in the die cavity, thereby form the product in the die cavity, be full of in the die cavity behind the plastics of molten condition, promote the push rod again, make the push rod slide in the ejector sleeve, the oral -lateral wall of moulding plastics thereby the push rod is contradicted to, make die cavity and runner plug up with the external world, thereby the effectual internal pressure of preventing leaks, it backflows to have avoided producing inside melting plastics production, thereby the effect of moulding plastics of product has been improved, and the pressurize structure is very simple also, the convenient manufacturing.
Description
Technical field
The utility model relates to a kind of mould manufacturing field, and more particularly, it relates to a kind of pressurize injection mold.
Background technology
Along with the development of Tool and Die Technology, the various shape of product requires more and more higher to mould, particularly Automobile Lamp, transparent face mask, photoconduction, need product surface without any flaw, and after mold injection, after mould is full of injection pressure, after injection machine stops pressurization, pressure in runner and die cavity is larger, thus produce, the plastics of melting there will be and backflow, product is caused to occur reprinting books in a reduce format, and during current Making mold, generally know that product stops pressurization after completely shaping again, thus add injection machine service time, thus greatly reduce the service life of injection machine.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is that providing a kind of facilitates the pressurize injection mold keeping pressure in die cavity and runner.
For achieving the above object, the utility model provides following technical scheme: a kind of pressurize injection mold, comprise dynamic model, cover half, described cover half is provided with injection hole, and described dynamic model is provided with runner, described injection hole communicates with runner, described dynamic model is provided with die cavity, and described runner communicates with die cavity, and described cover half is provided with ejector sleeve, slidably connecting push rod in described ejector sleeve, can conflict on injection hole sidewall in described push rod one end.
Preferably, described push rod is provided with the taper conflict head coordinated with injection hole near injection hole one end.
Preferably, described cover half and dynamic model are provided with some cooling water channels near side of flowing.
Compared with prior art, the beneficial effects of the utility model are: after matched moulds, injection machine carries out injection moulding in injection hole, the plastics of molten condition are successively through injection hole, runner arrives in die cavity, thus product is formed in die cavity, when after the plastics being full of molten condition in die cavity, promote push rod again, push rod is slided in ejector sleeve, the injection hole sidewall thus push rod is conflicted, die cavity and runner and the external world are shut, thus effectively prevent internal pressure from leaking, avoid the generation of generation inner molten plastics to backflow, thus improve the injection moulding effect of product, and pressure-maintaining structure also very simple, convenient manufacture.

Reference numeral: 1, dynamic model; 2, cover half; 21, injection hole; 22, die cavity; 3, runner; 4, ejector sleeve; 5, push rod; 51, taper conflict head; 6, cooling water channel.
Detailed description of the invention
Referring to figs. 1 through Fig. 3, the utility model pressurize injection mold embodiment is described further.
A kind of pressurize injection mold, comprise dynamic model 1, cover half 2, described cover half 2 is provided with injection hole 21, described dynamic model 1 is provided with runner 3, described injection hole 21 communicates with runner 3, described dynamic model 1 is provided with die cavity 22, described runner 3 communicates with die cavity 22, described cover half 2 is provided with ejector sleeve 4, push rod 5 is slidably connected in described ejector sleeve 4, described push rod 5 one end can be conflicted on injection hole 21 sidewall, after matched moulds, injection machine carries out injection moulding in injection hole 21, the plastics of molten condition are successively through injection hole 21, runner 3 arrives in die cavity 22, thus product is formed in die cavity 22, when after the plastics being full of molten condition in die cavity 22, promote push rod 5 again, push rod 5 is slided in ejector sleeve 4, injection hole 21 sidewall thus push rod 5 is conflicted, die cavity 22 is shut with the external world with runner 3, thus effectively prevent internal pressure from leaking, avoid the generation of generation inner molten plastics to backflow, thus improve the injection moulding effect of product, and pressure-maintaining structure also very simple, convenient manufacture.
Described push rod 5 is provided with the taper coordinated with injection hole 21 and conflicts 51 near injection hole 21 one end, 51 to coordinate with injection hole 21 because taper is conflicted, thus after push rod 5 promotes to injection hole 21, taper is conflicted and 51 to be conflicted completely on injection hole 21, thus can effectively seal up injection hole 21, and can continue to promote after injection moulding, the waste material in runner 3 is released.
Described cover half 2 is provided with some cooling water channels 6 with dynamic model 1 near side of flowing, and in cooling water channel 6, circulation cooling fluid, effectively lowers the temperature for die cavity 22 and runner 3, facilitate formed product.
The above is only preferred embodiment of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
