Description

Technical Field

[0001] The invention relates to the technical field of injection molds, in particular to a scraper mold with an interchangeable mold core. Background Art

[0002] In the early stages of precision injection mold development, customers are most concerned about delivery time. Electronic, medical, automotive, and environmental protection products are constantly being updated. Therefore, mold development must consider processing time and the ease of replacing internal mold components during later design changes. This ensures that the mold base of the old mold can be used with the core of the new mold, reducing the difficulty and processing cycle. The core, the most critical component of injection mold product molding, has a limited service life in the working environment of constant high temperature and high pressure. Therefore, the core is usually designed to be removable and replaceable. Traditional designs use a single core and can only mold a single set of products at a time. This cannot meet actual processing requirements when large-scale processing is required or when two molds need to be processed simultaneously when molds are limited. Furthermore, the ejector pins of traditional molds are fixedly mounted on the ejector plate, which is designed with a single hanging base and is manufactured with a single mold core. This leads to long production cycles and low utilization rates, and the ejector plate cannot be quickly replaced when the mold core is changed. Summary of the Invention

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] An embodiment of the present application provides a push scraper mold with an interchangeable mold core. The push scraper mold with an interchangeable mold core replaces the discharge pin 1902 through a flexible parts replacement mechanism, eliminating the process of disassembling the bolts, speeding up the mold change speed, and at the same time, through the anti-detachment mold connection mechanism, ensuring that the male mold 3 and the female mold 4 will not separate during the mold movement, causing damage to the internal components.

[0040] The following is a detailed description of the push scraper mold with interchangeable mold cores. It should be noted that the description order of the following embodiments is not intended to limit the preferred order of the embodiments.

[0041] The present application is described in detail below with reference to the accompanying drawings and specific implementation methods.

[0042] See also Figure 1-14 In the embodiment, a push scraper mold with interchangeable mold cores is provided, comprising: a lower mold fixing frame 1, the upper surface of the lower mold fixing frame 1 is fixedly connected with a mold foot 2, and the upper end of the mold foot 2 is fixedly connected to a male mold 3 by a bolt, a female mold 4 is placed on the upper surface of the male mold 3, and the upper end of the female mold 4 is fixedly connected to a pulling plate 5, a positioning guide column 7 is fixedly provided on the upper surface of the pulling plate 5, and the upper end of the positioning guide column 7 passes through the outer surface of the upper mold fixing frame 6, and the upper mold fixing frame 6 and the pulling plate 5 are fixedly installed by equal height screws 8, a positioning ring 9 is fixedly installed in the middle of the upper surface of the upper mold fixing frame 6, and A pull pin fixing plate 10 is embedded in the upper surface of the upper die fixing frame 6, a lower ejector plate 11 is placed on the upper surface of the lower die fixing frame 1 through a boss, and an upper ejector plate 12 is provided above the lower ejector plate 11, a support column 13 is fixedly provided on the upper surface of the lower die fixing frame 1, and a return pin 14 is provided on the upper surface of the upper ejector plate 12, an opener 15 is fixedly installed on the side surfaces of the male die 3 and the female die 4, a hanging module 16 is fixedly installed on the side surfaces of the male die 3 and the female die 4, an upper die core 17 is embedded in the outer surface of the female die 4, and an insert 18 is embedded in the upper surface of the upper die core 17;

[0043] In this embodiment, the push scraper mold with interchangeable mold core mainly includes a lower mold fixing frame 1, a mold foot 2, a male mold 3, a female mold 4, a pulling plate 5, an upper mold fixing frame 6, a positioning guide column 7, an equal height screw 8, a positioning ring 9, a pulling needle fixing plate 10, a lower ejector plate 11, an upper ejector plate 12, a support column 13, a return needle 14, an opener and closeer 15, a hanging module 16, an upper mold core 17, an insert 18, a flexible part replacement mechanism and an anti-slip mold connecting mechanism. The push scraper mold with interchangeable mold core provided in this scheme clamps and fixes the hanging platform of the discharge ejector 1902 by the lower ejector plate 11 and the upper ejector plate 12, so that the installation and disassembly of the discharge ejector 1902 does not require bolts, and the replacement is quick and convenient. At the same time, the unlocking directions of the rotating plate 2012 and the unlocking block 2013 are set in opposite directions, so that when either the rotating plate 2012 or the unlocking block 2013 is unlocked, the ejector 1902 can be easily removed. When locked, the rotating drum 2004 cannot rotate, resulting in the locking time of the upper connecting plate 2001 and the lower connecting plate 2002. When installing the mold, the hanging module 16 is used to lift the mold to the appropriate position of the installation machine, and the mold and the installation machine are positioned by the positioning ring 9. Then, the male mold 3 and the female mold 4 are fixed to the machine by the lower mold fixing frame 1 and the upper mold fixing frame 6 respectively. The gap between the lower mold fixing frame 1 and the male mold 3 is supported by the support column 13 and the mold foot 2. The lower ejector plate 11 and the upper ejector plate 12 are reset by the return needle 14. At this time, the anti-separation mold connecting mechanism is unlocked, and then the opener 15 and the hanging module 16 are removed to complete the installation of the mold and the machine. At this time, the molded product is ejected by the discharge ejector 1902, and the pulling plate 5 installed on the pulling needle fixing plate 10 drives the pulling needle to perform the pulling operation to ensure the smooth flow of the gate.

[0044] In some embodiments, the flexible parts replacement mechanism includes: a lower mold core 1901 embedded in the upper surface of the male mold 3, a discharge ejector pin 1902 passing through the lower surface of the lower mold core 1901, and a single hanging groove 1903 and a double hanging groove 1904 provided on the lower surface of the upper ejector plate 12. When replacing the mold core, the male mold 3 and the lower mold core 1901 are disassembled, and then the lower ejector plate 11 is removed, and the discharge ejector pin 1902 is slid relative to the lower ejector plate 11 and replaced. Then, the lower ejector plate 11 is rotated and reset. At this time, the lower ejector plate 11 is fitted with the upper ejector plate 12 to ensure that the hanging platform of the discharge ejector pin 1902 is stably engaged with the single hanging groove 1903 and the double hanging groove 1904. Then, the upper mold core 17, the insert 18 and the lower mold core 1901 are replaced, and the discharge ejector pin 1902 with appropriate signals maintains stability during ejection.

[0045] In some embodiments, the anti-slip mold connecting mechanism includes: an upper connecting plate 2001 fixedly installed on the outer surface of the pulling plate 5, a lower connecting plate 2002 fixedly installed on the outer surface of the male mold 3, an insertion rod 2003 fixedly set on the outer surface of the upper connecting plate 2001 and the lower connecting plate 2002, a rotating drum 2004 rotatably connected to the outer surface of the female mold 4, a limiting groove 2005 horizontally opened on the outer surface of the insertion rod 2003, a giving groove 2006 longitudinally opened on the outer surface of the insertion rod 2003, and a rotating drum 2004 fixedly set on the outer surface of the female mold 4. The limiting rod 2007 on the inner surface of the cylinder 2004, the limiting box 2008 fixedly set on the outer surface of the rotating cylinder 2004, the anti-slip rod 2009 with one end passing through the side surface of the limiting box 2008, the reset plate 2010 fixedly set between the two adjacent anti-slip rods 2009, the anti-rotation rod 2011 passing through the outer surface of the rotating cylinder 2004, the rotating plate 2012 fixedly connected to one end of the anti-rotation rod 2011, and the unlocking block 2013 passing through the outer surface of the rotating plate 2012. When the mechanism is in operation, the unlocking block 2013 is pressed through one end of the rotating plate 2012, so that the unlocking block 2013 can compress the spring and squeeze one end of the anti-slip rod 2009 inside the limit box 2008 on both sides through the inclined surface. The anti-slip rod 2009 slides and stretches the spring between the reset plate 2010 and the limit box 2008. At this time, one end of the anti-slip rod 2009 is disengaged from the engagement with the rotating plate 2012, so that the rotating plate 2012 can be pulled, pulling the rotating plate 2012 to stretch the rotating plate 2012 and the rotating drum 2004. The spring between them, at this time, the rotating plate 2012 drives the anti-rotation rod 2011 to disengage from the engagement with the insertion rod 2003, and then the rotating plate 2012 is rotated to make the rotating cylinder 2004 drive the limiting rod 2007 to rotate inside the limiting groove 2005 to the inside of the giving way groove 2006. At this time, when the male mold 3 is separated from the female mold 4, the limiting rod 2007 slides relative to the insertion rod 2003 through the giving way groove 2006, so that the upper connecting plate 2001 and the lower connecting plate 2002 are disconnected, which will not hinder the separation of the male mold 3 and the female mold 4.

[0046] In some embodiments, the single-type hanging table groove 1903 is designed as a long strip with elliptical ends, and a clearance hole is opened inside the single-type hanging table groove 1903, and the discharge pin 1902 of the single-type hanging table is fixed through the single-type hanging table groove 1903.

[0047] In some embodiments, the double-type hanging platform groove 1904 is L-shaped, and a clearance hole is opened inside the double-type hanging platform groove 1904, and the discharge ejector pin 1902 of the double-type hanging platform is fixed through the double-type hanging platform groove 1904.

[0048] In some embodiments, the upper connecting plate 2001 and the lower connecting plate 2002 are fixed to the pulling plate 5 and the male mold 3 respectively by bolts, and the upper connecting plate 2001 and the lower connecting plate 2002 are slidingly connected to the rotating cylinder 2004 by the insertion rod 2003. The upper connecting plate 2001 and the lower connecting plate 2002 are connected to the rotating cylinder 2004 by the insertion rod 2003 to keep the connection between the male mold 3 and the female mold 4 from loosening.

[0049] In some embodiments, the clearance grooves 2006 are evenly distributed on the outer surface of the insertion rod 2003, and the clearance grooves 2006 pass through the two facing end faces of the insertion rod 2003, so that the limiting rod 2007 can completely disengage from the engagement with the insertion rod 2003 when it slides inside the clearance groove 2006 to the end face of the insertion rod 2003.

[0050] In some embodiments, the limiting rod 2007 is evenly distributed on the inner surface of the rotating drum 2004, and one end of the limiting rod 2007 is engaged with the limiting groove 2005, and the limiting groove 2005 is penetrated by the giving groove 2006, so that when the limiting rod 2007 rotates inside the limiting groove 2005 to the giving groove 2006, it can slide up and down through the giving groove 2006 to disengage from the limiting groove 2005.

[0051] In some embodiments, the anti-slip rods 2009 on both sides of the limit box 2008 are staggered up and down, and the anti-slip rods 2009 on both sides of the limit box 2008 are set facing each other, and one end of the anti-slip rod 2009 is engaged with the outer surface of the rotating plate 2012, and a spring is connected between the reset plate 2010 and the limit box 2008, so that the anti-slip rod 2009 can limit the rotating plate 2012 from sliding in the direction away from the rotating drum 2004, to ensure that the rotating plate 2012 will not unlock itself due to vibration during transportation.

[0052] In some embodiments, a hole is provided on the outer surface of the insertion rod 2003 facing the anti-rotation rod 2011, and the anti-rotation rod 2011 is engaged with the insertion rod 2003 through the hole provided on the outer surface of the insertion rod 2003, so that the anti-rotation rod 2011 can block the rotation tendency of the rotating plate 2012 by engaging with the hole provided on the outer surface of the insertion rod 2003.

[0053] In some embodiments, the cross-section of the unlocking block 2013 is triangular in design, and one corner of the unlocking block 2013 is set opposite the middle of the limit box 2008. The unlocking block 2013 and the rotating plate 2012 are slidably connected, and a spring is connected between the unlocking block 2013 and the rotating plate 2012, and a spring is connected between the rotating plate 2012 and the rotating cylinder 2004, so that the unlocking block 2013 can drive the anti-slip rod 2009 to slide by squeezing one end of the anti-slip rod 2009 to release the anti-slip rod 2009 from restricting the sliding of the rotating plate 2012.

[0054] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
