Description

The mold ejection mechanism of order ejecting product and runner
Technical field
The present invention relates to the production mould of plastic product.
Background technology
Existing mold runner 2` and product 1` are all in slide block 3` moulding, as shown in Fig. 1 a, Fig. 1 b, Fig. 2 a, Fig. 2 b, Fig. 3 a, Fig. 3 b, the implication of number in the figure is as follows: product 1`, runner 2`, slide block 3`, ejector sleeve 4`, runner thimble 5`, Angle Pin 6`, ejector retainner plate 7`, thimble fixed head 8`, dynamic mould fixing plate 10`, eject apart from L 1
Owing to being side gate, runner 2` and product 1` link together when ejecting, and can not automatically separate, and need secondary operations.
State when Fig. 2 a, Fig. 2 b have shown the existing mold matched moulds, Fig. 3 a, state when Fig. 3 b has shown the existing mold die sinking.After the mould die sinking, slide block 3` breaks away from product 1` and runner 3` by under the drive of Angle Pin 6`, and because ejector sleeve 4` and runner thimble 5` are fixed on ejector retainner plate 7` and thimble fixed head 8`, mould ejects distance L ejecting thimble fixed head 8` 1, product 1` and runner 2` are ejected fully.In ejection process, product 1` and runner 3` or connection status can not be separated automatically.
Summary of the invention
The present invention will overcome the appeal shortcoming of prior art, provide a kind of be applicable in slide block molding runners, can realize the mold ejection mechanism that product separates with runner in the product ejection process.
The mold ejection mechanism of order ejecting product of the present invention and runner, comprise cover half fixed head, dynamic mould fixing plate, described dynamic mould fixing plate longitudinally moves back and forth, complete die sinking or matched moulds, the Angle Pin that be provided with the feed liquid entrance that coordinates with the spout of injection machine and material liquid flowing channel on described cover half fixed head, coordinates with slide block; Support on described dynamic mould fixing plate is provided with slide block, described slide block comprise can be involutory two slip slit bamboo or chopped woods, have the die cavity of product and runner on the involutory surface of described slip slit bamboo or chopped wood, described slip slit bamboo or chopped wood is provided with the guide groove that coordinates with described Angle Pin, and described slip slit bamboo or chopped wood is along laterally sliding longitudinally perpendicular to described; Described dynamic mould fixing plate is provided with ejector retainner plate and the thimble fixed head of lengthwise movement, and ejector retainner plate is connected on the thimble fixed head; Ejector sleeve one end is fixed on described ejector retainner plate, the other end inserts described die cavity, described runner is connected to an end of thimble, and described ejector sleeve and thimble are respectively with product, runner ejection slider, and ejecting direction is that longitudinally the automatic mold fixed head points to the cover half fixed head;
It is characterized in that: thimble longitudinally is slidably disposed on ejector retainner plate and thimble fixed head, the shaft shoulder on the runner thimble coordinates with pushing and pressing parts on being arranged on ejector retainner plate or thimble fixed head, lag behind ejector retainner plate ejecting the above pushing and pressing parts of direction, make product be ejected prior to runner.
Further, described ejector retainner plate and thimble fixed head are provided with the chute that ejects direction along described, and described runner thimble is arranged in described chute, and described runner thimble is provided with the shaft shoulder, and described pushing and pressing parts are arranged on the thimble fixed head.
Perhaps, described ejector retainner plate and thimble fixed head are provided with the chute that ejects direction along the runner thimble, and described runner thimble is arranged in described chute, and described runner thimble is provided with the shaft shoulder, described thimble fixed head is provided with the shaft shoulder, and described pushing and pressing parts are arranged on ejector retainner plate.
Further again, described chute has width greater than the widened section of remainder, and the protuberance of described runner thimble is slidably disposed in described widened section; The ends restrict of described widened section the sliding stroke of described protuberance, consist of described pushing and pressing parts.
By novel mould ejection mode, first slide block to be taken out out after die sinking, ejector retainner plate and thimble fixed head are to ejecting the direction motion.Because the pushing and pressing parts lag behind the shaft shoulder on the runner thimble, ejector sleeve prior to the runner thimble to ejecting the direction motion.Its effect is: first top product, runner is motionless, and product is separated with runner.Continue again to eject, product and runner are ejected together, completed like this action that ejects of whole secondary mould, product is separated with runner, need not artificial secondary operations, directly reduce production costs, raise the efficiency.
Advantage of the present invention is: automatically realize separating of product and runner in the product ejection process, need not artificial secondary operations, directly reduced production cost, promoted efficient.
