Description
Technical field
The present invention relates to injection mold, particularly relate to a kind of runner lock for injection mould with different cavities, belong to the mould of plastics field.
Background technology
It is that plastic raw materials is injected in the mould that injection machine is produced plastic products, enters hot flow path by the glue muzzle, flows in the goods die cavity again, forms goods.Be in die cost and goods market and consider, require a width of cloth mould to produce two kinds of difformity goods simultaneously sometimes, i.e. the different chamber of a mould (two chambeies), its advantage is to enhance productivity, and reduces production costs.But,, continue the cost of material waste of using the uncontrollable production of the different cavity mould of a mould to cause if when prior art only need be produced the goods of a kind of shape wherein; If open a secondary mould in addition, then increased the cost of investment of mould again.
Summary of the invention
The objective of the invention is in order to overcome the shortcoming of prior art, a kind of lock body of installing in runner is provided, the control runner exit can select to process a kind of or two kinds of goods in injection moulding, raise the efficiency the runner lock for injection mould with different cavities that reduces cost.
The technical scheme of runner lock for injection mould with different cavities of the present invention is: comprise compound plate and following compound plate, last compound plate connects solid plate, two secondary special-shaped cover half cavity block are installed in the solid plate, install on the following compound plate, following ejector retainner plate and counterdie pin, on the counterdie pin moving platen is installed, two secondary special-shaped movable model cavity inserts are installed in the moving platen, two secondary special-shaped cover half cavity block and two secondary special-shaped movable model cavity inserts are formed two secondary special-shaped product die cavities, the two secondary special-shaped product die cavities runner of respectively hanging oneself is communicated with sprue, be equipped with the glue muzzle in the sprue, the oral area of glue muzzle has centring ring, two secondary special-shaped product die cavities are formed the goods die cavity with the goods core separately, it is characterized in that between described two runners runner lock being installed, and described runner lock comprises lock body, be shaped at least three passages in the lock body, three passages match with runner respectively.
Runner lock for injection mould with different cavities of the present invention, between two runners, runner lock is installed, have three passages in the runner lock at least, when two secondary special-shaped die cavitys are produced simultaneously, wherein two passages of three passages in the runner lock lock body cooperate with two runners respectively, and sprue is communicated with two runners; When two secondary special-shaped die cavitys only need be produced a kind of goods, rotate runner lock, one of them passage of three passages is communicated with a runner, another runner is blocked by the runner lock body, and plastic raw materials is not flowed into.The technical program is simple in structure, can control the outlet of runner effectively, can select to produce simultaneously two kinds of difformity goods or wherein a kind of shape goods, but does not waste plastic raw materials and increase the mould cost of investment, has significant good effect.
Runner lock for injection mould with different cavities of the present invention is shaped on the interior angle hole in its described lock body, and when needs were regulated the outlet of runner, in the insertion interior angle hole with spanner, rotating spanner drove lock body and rotates, and regulates the outlet of runner.Its described lock body is a cylinder, and it is convenient to rotate during adjusting.Be shaped on through hole in its described lock body, ejector beam is installed in the through hole, an end of ejector beam is connected on the ejector retainner plate, the other end of ejector beam contacts with the raw material handle, and after the die sinking, the raw material handle is taken the glue muzzle out of with the moving platen die sinking, drive ejector beam by ejector retainner plate again and withstand on the raw material handle, goods are ejected.Its described runner lock is installed in the movable model cavity insert, and the lock body of runner lock bottom is shaped on step, and step blocks the movable model cavity insert, and is convenient during rotation.Its described runner lock is installed in the movable model cavity insert, and is fastened by screw, and it is firm to install.
