Abstract
The invention discloses an injection mold with a variable hole diameter of a main runner. The injection mold comprises a movable mold and a fixed mold; the movable mold comprises a movable template, a mold core and an ejecting mechanism, and the mold core and the ejecting mechanism are installed on the movable template; after the movable template, the fixed mold and the mold core are closed, a hollow cavity is formed, and the hollow cavity is a mold cavity; a main runner hole communicated with the mold cavity is formed in the fixed mold, a main runner pipe is an elongated hollow pipe and is tightly installed in the main runner hole, one end of the main runner pipe is an inlet, and the other end of the main runner pipe is an outlet. According to the injection mold with the variable hole diameter of the main runner, the main runner pipe is replaced as required, so that injection molding is conducted on materials with different injection molding requirements in the same mold conveniently; the structure of the injection mold is simple, the injection mold is durable, and the injection mold is suitable for being applied to an injection molding process.
Description
Technical field
The present invention relates to the injection mold that a kind of sprue aperture is variable, belong to injection molding technology field.
Background technology
A kind of processing method used when injection mold (Injectionmold) is some complex-shaped parts of batch production, is mainly used in industrial circle.Injection mold process is that the material melted that is heated is injected die cavity by high pressure, after cooling curing, obtains formed products.Mould is primarily of compositions such as running gate system, forming part and constitutional details.Wherein running gate system running gate system is also known as flow passage system, it is one group of feeding-passage of plastic melt being guided into die cavity by nozzle of injector, usually by sprue, runner, the compositions such as cast gate, sprue connects the one section passage of injection machine nozzle to runner or die cavity in mould, the porch of sprue connects with injection molding machine nozzle, when sprue inlet diameter should slightly larger than nozzle diameter to avoid flash, and intercepting of preventing both from occurring because being connected inaccurate, in addition, the cross-sectional sizes of sprue has a significant impact the flow velocity of fluid in injection moulding process, and rate of flow of fluid directly determines Forming Quality and the production efficiency of plastic products, therefore when using same mould to produce the goods of different materials, because injection raw material changes, the bore of injection molding machine nozzle and all changing to the requirement of flow velocity, if now the import size of sprue is constant, sectional area is constant, then easily there is flash, intercept, sticking to moulds etc. are abnormal.
Summary of the invention
Technical problem to be solved by this invention is to provide the variable injection mold in a kind of sprue aperture, can prevent from not mating because of sprue and nozzle or sprue sectional area does not reach and to require and that injection moulding process occurs is abnormal.
For solving above technical problem, the technical solution used in the present invention is: the injection mold that a kind of sprue aperture is variable, comprise dynamic model and cover half, described dynamic model comprises moving platen, be installed on the core rod on moving platen and ejecting mechanism, the cavity formed after described moving platen, cover half and core rod close is die cavity, described cover half is provided with the sprue hole communicated with die cavity, in described sprue hole, close installation has main flow deferent, described main flow deferent is an elongated hollow pipe fitting, one end of described main flow deferent is import, and the other end is outlet.
The inner surface in described sprue hole and the outer surface of described main flow deferent are provided with the screw thread of mutually occlusion, achieve the compact siro spinning technology of sprue hole and main flow deferent, and when preventing injection moulding, fluid enters seam or main flow deferent is deviate from.
The sectional area of described main flow deferent is increased to Way out gradually by described import, so that the demoulding of runner excrescence.
Described outlet is connected with cast gate, and the sectional area of described cast gate is less than described discharge area, achieves and controls stream speed, and is convenient to goods and is separated with flow passage system.
Described outlet connects with runner, injection moulding while being convenient to carry out multiple die cavity.
The thimble that described ejecting mechanism comprises top board and is connected with top board.
The setting that the present invention adopts sprue hole and main flow deferent to match, can according to the main flow deferent needing the import of replacing different pore size of Shooting Technique, achieve the cooperation from the nozzle of different bore, and can need according to injection moulding the main flow deferent selecting different cross-sectional, to make fluid reach most suitable flow velocity, prevent flash in injection moulding process, intercept, the generation of the abnormal problem such as sticking to mould.
Therefore, the injection mold that a kind of sprue aperture provided by the present invention is variable, can change main flow deferent as required, be convenient to the injection moulding of the material carrying out different injection moulding requirement on same mould, structure is simple, durable, is applicable to being applied in Shooting Technique.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.Following examples only for technical scheme of the present invention is clearly described, and can not limit the scope of the invention with this.
The injection mold that a kind of sprue aperture is as shown in Figure 1 variable, comprise dynamic model and cover half 1, described dynamic model comprises moving platen 2, be installed on the core rod 3 on moving platen and ejecting mechanism, the cavity formed after described moving platen 2, cover half 1 and core rod 3 is closed is die cavity, described cover half 1 is provided with the sprue hole 4 communicated with die cavity, in described sprue hole 4, close installation has main flow deferent 5, described main flow deferent 5 is an elongated hollow pipe fitting, one end of described main flow deferent 5 is import, and the other end is outlet.
The inner surface in described sprue hole 4 and the outer surface of described main flow deferent 5 are provided with the screw thread of mutually occlusion, achieve the compact siro spinning technology of sprue hole 4 and main flow deferent 5, and when preventing injection moulding, fluid enters seam or main flow deferent 5 is deviate from.
The sectional area of described main flow deferent 5 is increased to Way out gradually by described import, so that the demoulding of runner excrescence.
Described outlet connects with runner, injection moulding while being convenient to carry out multiple die cavity.
The thimble 7 that described ejecting mechanism comprises top board 6 and is connected with top board.
The setting that the present invention adopts sprue hole 4 and main flow deferent 5 to match, can according to the main flow deferent 5 needing the import of replacing different pore size of Shooting Technique, achieve the cooperation from the nozzle of different bore, and can need according to injection moulding the main flow deferent 5 selecting different cross-sectional, to make fluid reach most suitable flow velocity, prevent flash in injection moulding process, intercept, the generation of the abnormal problem such as sticking to mould.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvement and distortion, these improve and distortion also should be considered as protection scope of the present invention.
