Abstract
The invention discloses a single-thimble acceleration ejection mechanism of an injection mold. The mechanism comprises a mold movable template, wherein a movable mold insert is mounted in the movable template, and is provided with a product mold cavity; a thimble plate is arranged below the movable template, and is connected with a thimble; the thimble penetrates through the movable template and the movable mold insert to fit a rib hole part of the product mold cavity; a turning plate is arranged on the thimble plate at one side of the thimble; the head part of the turning plate is connected with the thimble; a stopper is mounted below the movable template; when the thimble plate is upwards ejected, the tail part of the turning plate is touched with the stopper to upwards turn the turning plate so as to drive the thimble to be accelerated and ejected; the rib hole part of the product and the thimble are ejected out firstly; the thimble plate is continuously upwards ejected to drive other thimbles to eject the product outside the mold; and the mold release of the product is smooth.
Description
Technical field
The present invention relates to a kind of injection mold list thimble and accelerate ejecting mechanism, belong to injection mold field.
Background technology
Adopt injection mold to produce plastic product, such as car trim etc., there are more muscle, pin and hole etc. in the back side of this series products; in die design process; the core at the positions such as these muscle, pin and hole is often directly replaced by thimble (push rod), and namely product is connected on thimble, therefore; when thimble ejects with product stripping; product is bonded on thimble sometimes, causes product cannot Automatic-falling, even causes mould stuck; injection machine is shut down, and reduces production efficiency.
Summary of the invention
The object of the invention is the shortcoming in order to overcome prior art, providing a kind of and adopting seesaw mode, accelerating single thimble and eject, make product stripping injection mold list thimble acceleration smoothly ejecting mechanism.
The technical scheme that injection mold list thimble of the present invention accelerates ejecting mechanism is: comprise mould moving platen, in moving platen, moving die insert is installed, moving die insert is arranged product die cavity, ejector retainner plate is had under moving platen, connecting ejector pin on ejector retainner plate, thimble matches with the position, muscle hole of product die cavity through moving platen and moving die insert, the ejector retainner plate that it is characterized in that described thimble side arranges seesaw, the head connecting ejector pin of seesaw, under moving platen, block is installed, when ejector retainner plate pushes up, afterbody and the block of seesaw touch mutually and seesaw are tilted.
Injection mold list thimble of the present invention accelerates ejecting mechanism, main feature arranges seesaw on ejector retainner plate, the head connecting ejector pin of seesaw, under moving platen, block is installed, when mold releasability, ejector retainner plate is by injection machine powered upwards jack-up, drive thimble and seesaw upper top simultaneously, when pushing up stop location, the afterbody of seesaw touches mutually with block, press down relative to block, the head of seesaw is tilted, thus drive thimble to accelerate to eject, the position, muscle hole of product and thimble are first deviate from, ejector retainner plate continues upper top, drive other thimble by outside product ejection die, product stripping is smooth.
Injection mold list thimble of the present invention accelerates ejecting mechanism, and described thimble is shaped with recess, and recess matches with the head of seesaw, and the head of seesaw is inserted in recess, coordinates reliable.Described ejector retainner plate installs fixed block, and fixed block connects seesaw through pin-and-hole pin, easy to connect by pin-and-hole pin, movable, and seesaw tilts easily.Be shaped with locating hole in described fixed block, seesaw is shaped with backstay, backstay matches with locating hole, seesaw is installed reliable.
Accompanying drawing explanation
Fig. 1 is that injection mold list thimble of the present invention accelerates ejecting mechanism structural representation;
Fig. 2 is that seesaw of the present invention coordinates schematic diagram with thimble.
Detailed description of the invention
The present invention relates to a kind of injection mold list thimble and accelerate ejecting mechanism, as shown in Figure 1 and Figure 2, comprise mould moving platen 1, moving die insert 2 is installed in moving platen, moving die insert is arranged product die cavity, ejector retainner plate 4 is had under moving platen, connecting ejector pin 5 on ejector retainner plate, thimble 5 matches with the position, muscle hole 3 of product die cavity through moving platen 1 and moving die insert 2, the ejector retainner plate 4 of described thimble side arranges seesaw 6, head 7 connecting ejector pin 5 of seesaw 6,1 time block 8 is installed at moving platen, when ejector retainner plate pushes up, afterbody 9 and the block 8 of seesaw touch mutually and seesaw 6 are tilted.The main feature of this programme arranges seesaw 6 on ejector retainner plate 4, head 7 connecting ejector pin 5 of seesaw 6, 1 time block 8 is installed at moving platen, when mold releasability, ejector retainner plate 4 is by injection machine powered upwards jack-up, drive thimble 5 and seesaw 6 upper top simultaneously, when pushing up block 8 position, the afterbody 9 of seesaw 6 touches mutually with block 8, press down relative to block 8, the head 7 of seesaw 6 is tilted, thus drive thimble 5 to accelerate to eject, the position, muscle hole of product and thimble are first deviate from, ejector retainner plate 4 continues upper top, drive other thimble by outside product ejection die, product stripping is smooth.Described thimble 5 is shaped with recess 10, and recess 10 matches with the head 7 of seesaw 6, and the head of seesaw is inserted in recess, coordinates reliable.Described ejector retainner plate 4 installs fixed block 12, and fixed block 12 connects seesaw 6 through pin-and-hole pin 11, easy to connect by pin-and-hole pin, movable, and seesaw tilts easily.Be shaped with locating hole 13 in described fixed block 12, seesaw 6 be shaped with backstay 14, backstay 14 matches with locating hole 13, seesaw is installed reliable.
