[0044] To make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features therein can be combined with each other without conflict.

[0045] It is to be understood that these descriptions are illustrative only and are not intended to limit the scope of the invention.

[0046] A mold injection molding material removal jig provided by some embodiments of the present invention will be described below with reference to the accompanying drawings.

[0047] Example 1:

[0048] Combine Figures 1-10 As shown, the present invention provides a mold injection molding material removal fixture, including a suspension mechanism 100 and a transmission mechanism 400, three groups of workpiece suction mechanisms 200 installed on the suspension mechanism 100, a transmission mechanism 400 installed on the three groups of workpiece suction mechanisms 200, an air extraction component 300 installed on the three groups of workpiece suction mechanisms 200, a cooling and curing mechanism 500 installed in the workpiece suction mechanism 200, and a negative pressure implementation mechanism 600 installed in the workpiece suction mechanism 200.

[0049] The suspension mechanism 100 includes a support plate 110, an outer frame 120, a hydraulic arm 130, and a compression spring 140. The workpiece suction mechanism 200 includes a protective tube 210, an end tube 220, a fresh air bin 230, a first convex ring 240, a shaft sleeve 250, a linkage gear shaft 260, an air inlet member 270, a second convex ring 280, and a guide channel 290. The air extraction assembly 300 includes a joint 310, an external air pipe 320, and an adapter air pipe 330. The transmission mechanism 400 includes a chassis 410, a motor 420 and a chain 430. The cooling and curing mechanism 500 includes a refrigeration chamber 510, an insulation tube 520, a wire 530, a semiconductor refrigeration plate 540, a reinforcement ring gasket 550, a negative pressure ring gasket 560, a beam 570, a first pull rod 580 and a second pull rod 590. The negative pressure implementation mechanism 600 includes a tray 610, a plug 620, a spring 630 and a sealing ring 640.

[0050] The suspension mechanism 100 includes a support plate 110, three compression springs 140 disposed at the bottom of the support plate 110, and an outer frame 120 mounted within the support plate 110. Two locking bolts are connected to the circular end of the outer frame 120, and a hydraulic force arm 130 is mounted within the circular end.

[0051] Two locking bolts are adapted to be pressed against the outer wall of the hydraulic arm 130;

[0052] The workpiece suction mechanism 200 includes a protective tube 210, a fresh air bin 230 mounted on the protective tube 210, and an air inlet member 270 disposed in the inner cavity of the fresh air bin 230;

[0053] The air extraction assembly 300 is disposed outside the three protection tubes 210 and is used to exhaust air from the inner cavities of the three protection tubes 210;

[0054] The air extraction assembly 300 includes a connector 310 connected to the threaded end tube of the end tube 220, a transfer air pipe 330 connected to two adjacent connectors 310, and an external air pipe 320 connected to one of the connectors 310;

[0055] The transmission mechanism 400 is used to provide kinetic energy to the three air inlet members 270;

[0056] The transmission mechanism 400 includes a chassis 410 fixedly mounted on one of the protective tubes 210 and a motor 420 fixedly mounted inside the chassis 410. A gear is mounted on a transmission shaft in the motor 420, and a chain 430 is connected to the gear.

[0057] The cooling and curing mechanism 500 includes a refrigeration chamber 510 installed at the bottom end of the protective tube 210, a semiconductor refrigeration plate 540 arranged in the inner cavity of the refrigeration chamber 510, and a negative pressure ring gasket 560 arranged inside the refrigeration chamber 510;

[0058] The negative pressure implementing mechanism 600 includes a plug 620 disposed in the inner cavity of the protection tube 210 and a tray 610 movably mounted on the top of the plug 620 .

[0059] At present, injection molded workpieces are mainly made in the inner cavities of the closed upper and lower molds, and the traditional material removal jig is installed in the inner cavity of the lower mold. When the upper mold is evacuated from the lower mold, the jig set inside the lower mold can push the injection molded workpiece outward. However, this type of injection molded part needs to reach a certain degree of cooling before it can be pushed outward by the jig inside the lower mold. Once the cooling time of the injection molded part is too short and the area of ​​pressure exerted by the jig on the workpiece is small, the jig inside the lower mold will cause local bulging or damage or bulging due to the small area of ​​contact with the workpiece.

[0060] When the device is in use, the hydraulic arm 130 extends outward from the inner cavity of the hydraulic mother pipe, and the three protective tubes 210 movably installed inside the support plate 110 will approach the workpiece in the lower mold. As the three protective tubes 210 are pressed against the surface of the workpiece, the three compression springs 140 can prompt the three protective tubes 210 to adapt and fit the streamlined surface of the workpiece. At this time, the three refrigeration chambers 510 that are close to and in contact with the workpiece will quickly harden the surface of the workpiece under the action of continuously releasing cold air, and ultimately reduce the deformation pressure caused by the three refrigeration chambers 510 on the surface of the workpiece. As the external air pipe 320 discharges air outward, the three joints 310 connected by the two adapter air pipes 330 can draw the inner cavities of the three protective tubes 210 outward. Vacuum is created, and the plug 620 will be lifted upward. At the same time, the first pull rod 580 and the second pull rod 590 push the reinforcing ring gasket 550 and the negative pressure ring gasket 560 in opposite directions under the support of the beam 570, until the bottom end of the negative pressure ring gasket 560 is pressed against the hardened surface of the workpiece. As the plug 620 continues to rise, the cavity between the plug 620 and the negative pressure ring gasket 560 will form a negative pressure state. Finally, the three negative pressure ring gaskets 560 can mechanically tighten the three hardened surfaces of the workpiece until they are fixed. As the hydraulic pressure arm 130 contracts and resets toward the inner cavity of the hydraulic mother pipe, the injection molded workpiece can finally be pressurized at multiple points, thereby improving the pressure balance of the workpiece to avoid the problem of extrusion damage due to a smaller contact area.

[0061] Example 2:

[0062] Combine Figure 4-Figure 8 As shown, based on Example 1, the workpiece suction mechanism 200 further includes an end tube 220 fixedly mounted in the middle of the protective tube 210, a sleeve 250 mounted on the fresh air bin 230, and a linkage gear shaft 260 movably mounted inside the sleeve 250;

[0063] Two second protruding rings 280 are formed on the inner wall of the protection tube 210;

[0064] Two first protruding rings 240 are formed on the inner wall of the fresh air bin 230;

[0065] The inner wall of the protection tube 210 is provided with a plurality of flow guide channels 290 distributed in a circumferential manner;

[0066] The top of the fresh air bin 230 is provided with densely distributed air holes, and the fresh air bin 230 and the protective tube 210 are both made of thickened aluminum alloy material;

[0067] The air inlet member 270 is composed of a stainless steel ring buckle, a fan blade installed inside the stainless steel ring buckle, and a ring tooth installed on the top of the stainless steel ring buckle;

[0068] The two first protruding rings 240 are adapted to be clamped on the top and bottom of the stainless steel buckle.

[0069] When the motor 420 is started, the gear on its internal transmission shaft will drive the chain 430. At this time, the chain 430 will simultaneously drive the three linked gear shafts 260, and the air inlet piece 270 positioned and constrained by the two first convex rings 240 can be jointly driven by the linked gear shafts 260. At this time, the air inlet piece 270 located in the middle of the inner cavity of the fresh air bin 230 will rotate at high speed. At this time, the outside air will be sucked in from the air holes on the top of the fresh air bin 230, and finally enter the inner cavity of the refrigeration bin 510 along multiple guide cavities 290. At this time, the powered semiconductor refrigeration plate 540 will continue to cool the transferred airflow, and the cooled airflow will continue to blow from the slot at the bottom of the refrigeration bin 510 toward the exposed surface of the injection molded workpiece, so that multiple parts of the workpiece can be cooled quickly to increase the pressure-bearing area of ​​the workpiece, thereby ensuring that the hardened parts of the surface of the injection molded workpiece can be effectively adsorbed and fixed.

[0070] Example 3:

[0071] Combine Figure 3-Figure 8 As shown, based on Example 1, the cooling and curing mechanism 500 further includes a reinforcing ring pad 550 installed on the top of the negative pressure ring pad 560. Two auxiliary clamps are installed on the top of the reinforcing ring pad 550, and the two auxiliary clamps are respectively connected to a first pull rod 580 and a second pull rod 590;

[0072] The inner wall of the refrigeration chamber 510 is equipped with a beam 570 supported by a first tie rod 580 and a second tie rod 590, an insulation tube 520 is installed on the outer wall of the refrigeration chamber 510, and two wires 530 are connected to the connector of the semiconductor cooling plate 540;

[0073] Two wires 530 are adapted to pass through the interior of the thermal insulation tube 520 .

[0074] Among them, two main chucks are installed at the bottom end of the plug 620, and the top ends of the first pull rod 580 and the second pull rod 590 are movably installed on the two main chucks respectively. At this time, the beam rod 570 fixedly installed on the inner wall of the refrigeration warehouse 510 can provide sufficiently stable supporting force for the cross-arranged first pull rod 580 and the second pull rod 590. As the joint 310 discharges air outward, the inner cavity of the protective tube 210 is vacuumed, which will prompt the plug 620 to lift upward. Finally, the two main chucks at the bottom of the plug 620 will pull the first pull rod 580 and the second pull rod 590 to extend, thereby ensuring that the reinforcing ring gasket 550 and the negative pressure ring gasket 560 press the shell of the workpiece surface cooling, and finally the negative pressure cavity formed between the plug 620 and the negative pressure ring gasket 560 can adsorb the hardened shell of the workpiece. At this time, the injection molded workpiece can be fixed at multiple points and can be quickly removed.

[0075] Example 4:

[0076] Combine Figure 4 and Figure 9 As shown, in the above embodiment, the negative pressure implementing mechanism 600 further includes a spring 630 disposed outside the plug 620 and two sealing rings 640 mounted on the plug at the bottom of the wire 530;

[0077] The tray 610 is composed of a reinforced inner ring, a reinforced outer ring, and a plurality of guide rods, and the reinforced outer ring is adapted to be installed between the two second protruding rings 280;

[0078] The top end of the plug 620 is movably installed in the reinforced inner ring, and the top end of the spring 630 is adapted to be pressed against the bottom end of the reinforced inner ring.

[0079] By installing the reinforced outer ring in the gap between the two second convex rings 280, as the negative pressure in the inner cavity of the plug 620 and the protective tube 210 increases, the plug 620 will be pressurized and continue to rise. At this time, the rising plug 620 can provide power for the negative pressure ring pad 560 and the reinforcing ring pad 550 to descend and press the workpiece shell. Since the workpiece is made of injection molding, there will be certain potholes on its surface. As the bottom end of the negative pressure ring pad 560 continues to squeeze the hardened shell of the workpiece, the negative pressure state formed by the cavity of the protective tube 210 and the refrigeration chamber 510 will suck the workpiece tightly, and finally ensure that the workpiece is quickly fixed, and then the injection-molded workpiece in the lower mold can be safely removed, thereby reducing deformation and damage when the pressure area of ​​the workpiece is small.

[0080] The working principle and use process of the present invention are as follows: After the injection molded part is formed, as the upper mold is separated from the lower mold, the hydraulic pressure arm 130 can be operated. As the hydraulic pressure arm 130 extends outward from the inner cavity of the hydraulic mother rod, the ports at the bottom ends of the three protective tubes 210 and the three refrigeration chambers 510 approach the injection molded part inside the lower mold. When the bottom ends of the three refrigeration chambers 510 are in contact with the surface of the injection molded part, the continuously running motor 420, and its internal transmission shaft drives the chain 430. At this time, the three linkage gears The shaft 260 will be driven at the same speed. At this time, the three linked gear shafts 260 will rotate at high speed inside the three shaft sleeves 250, and the three first convex rings 240 will rotate in real time. At this time, the external air will be sucked into the interior of the fresh air bin 230 and transferred to the interior of the three refrigeration bins 510 along multiple guide cavities 290. After the transferred airflow passes through the semiconductor refrigeration plate 540, the cooled airflow will be quickly lowered from the notch at the bottom of the refrigeration bin 510 to the pressure-applied part surface. The cooling part is cooled until it hardens quickly. After the external air pipe 320 exhausts the air, the three joints 310 respectively installed on the threaded sections of the three end pipes 220 can extract the air in the inner cavity of the three protective tubes 210. At the same time, negative pressure will be generated in the inner cavity of the protective tube 210 and the plug 620. As the bottom end of the plug 620 continues to rise, the two main clamps at its bottom end will simultaneously stretch the beam 570 and the first pull rod 580, and the reinforcing ring gasket 550 and the negative pressure ring gasket 560 will cool and harden towards the injection molded part. The surface of the lower mold is pressed down until the bottom end of the negative pressure ring gasket 560 is in contact with the surface of the injection molded part. Then, a negative pressure state is formed in the cavity between the bottom end of the plug 620 and the negative pressure ring gasket 560. Finally, the three surfaces of the injection molded part can be adsorbed and fixed. As the hydraulic force arm 130 is reset toward the inside of the hydraulic mother pipe, the three pressurized protective tubes 210 can finally take the injection molded part out of the lower mold, thereby avoiding the problem of local bulge of the injection molded part caused by the push rod set inside the lower mold exerting pressure on the uncooled part of the injection molded part.

[0081] Although the 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 the embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the claims and their equivalents.
