Injection mold with insert activity

2021-02-03
Injection mould should be paid attention to in the design of processing: screw thread core backend axis milling square, insert the Angle type injection molding machine screw within the square hole, combining a model open mode, because of the square shaft connection, the threaded core in the process to exit the plastic screw rotation.
Screw thread core in the bushing should not be too tight or too loose, want to consider the factors of thermal expansion at the same time, prevent the core and bushing glue adhesion, such as mould temperature is too high, the available cooling water to cool.
the insert structure of die, its advantage is not only save the inclined guide pillar and slide block design and manufacture of complex structure, make the mould shape narrowing, greatly reduces the mold manufacturing costs, more important is in some cannot arrange technoloy such as structure, must use activity form inserts. The downside of this approach is the poor safety operation, the production efficiency is low. For injection mold molding plastic parts with screws, thread or thread type ring can be used.
Angle of injection molding with orthogonal type injection mold, injection mold, also known as this kind of mold in the direction of feed when molding and mould direction perpendicular to each other. Right Angle type injection mould of the mainstream way open in move, on either side of the mold parting surface, the cross-sectional area is usually constant, often assumes the circular or oblate, for this and other injection mold are distinguished. In the opening of a mainstream way of end, in order to prevent injection nozzle with mainstream crossing the wear and deformation, sets the quenching can be replaced with blocks.
type ring thread core or thread insert is essentially activities. Threaded core or cavity, activity type ring with the die structure were introduced together with, then by hand or special tools will type ring threaded core or spin out from the plastic pieces, then put it in the mould cavity for the next injection molding. Design with activities activities should be paid attention to when the injection mold insert insert in the mould should be reliable positioning, he and put the mating surface of holes should be designed as a commonly 3 & deg; - 5° Slope, in order to keep the fit clearance.
due to the needs of the stripping process, some of the mold insert the activity needs, set up under the push rod, launched activities when open mold insert mold outside, to the next activity was laid insert, push rod must be reset in advance, otherwise the activities set piece will not be able to put into the installation hole. Design activity to insert into clamping part when contact with fixed mold parting surface, the push rod will introduce its launch is not all the mounting holes, retain part of activities in order to install insert, clamping, to set the mold parting surface will be activities placed by all insert into the hole.
this kind of design method is often will push rod and activity insert with screw thread connection.
some plastic parts, although there is a side hole and concave and convex shape, but is there any special requirements, such as mold needs to be set on the threaded core or threaded ring etc. This mould, it's sometimes difficult to use side core-pulling mechanism to meet the requirements of side core-pulling. In order to simplify the mould structure, and will not be using inclined guide pillar, technoloy etc, but in local Settings activity cavity insert. Open mode, these activities set piece not simple separation along the direction of mould and plastic parts, but must be in the injection molding processing parts when parting, together with the plastic parts removed from the mould, then by hand or with special tools it separated with plastic parts, before the next clamping injection, and puts it into a mould again.
activity insert in the mold is easy to slide position, shall have the elastic connection device to be stable, so as to avoid falling when clamping insert or shift caused damage to scrap or mould, after forming, insert pull with plastic parts, and then use a special tool to insert removed from the plastic parts. Gouges where whole pieces were missing the elasticity of the relay is weak, so the elastic type of installation is suitable for diameter less than 8 mm insert. In order to prevent accidents due to activities set piece is not fully in place damage cavity, activity insert should be slightly lower than the hardness of mold hardness.
