[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0032] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.
[0033] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-9 A quick replacement and positioning auxiliary device includes a lower mold frame 11, a lower mold core 12, an upper mold frame 13, an upper mold core 14, a push cylinder 15, a disassembly and replacement mechanism 1 2, and a disassembly and replacement mechanism 2 3.
[0034] The lower mold base 11 has a tooling groove 111 at its top for placing the lower mold core 12. The lower mold core 12 has symmetrically arranged limiting grooves 121 on its right side. Multiple ejector cylinders 15 for demolding are fixedly connected to the bottom of the lower mold base 11. The output ends of the ejector cylinders 15 slide through the lower mold base 11 and are fixedly connected to the bottom of the upper mold base 13. The upper mold base 13 has a tooling groove 131 at its bottom for placing the upper mold core 14. An injection port 16 for spruing is located at the top of the upper mold base 13. Limiting grooves 141 are symmetrically arranged on both sides of the upper mold core 14. The limiting grooves 141 are through grooves. A disassembly and replacement mechanism 3 for quickly replacing the lower mold core 12 is connected to the right end of the lower mold base 11, and a disassembly and replacement mechanism 2 for quickly replacing the upper mold core 14 is connected to the right end of the upper mold base 13. The limiting grooves 141 are through grooves.
[0035] The disassembly and replacement mechanism 2 includes an auxiliary positioning component 21 for pre-positioning the upper mold core 14 and a fixing component 22 for limiting and fixing the upper mold core 14. The auxiliary positioning component 21 is connected to the top of the upper mold frame 13, and the fixing component 22 is connected to the right end of the upper mold frame 13.
[0036] In this invention, the lower mold core 12 is quickly replaced via the disassembly and replacement mechanism 23. The upper mold core 14 is released from its fixation via the fixing component 22, and the upper mold core 14 is released from its limiting position via the auxiliary positioning component 21. The upper mold core 14 is then replaced by placing it inside the tooling slot 131. The auxiliary positioning component 21 then provides auxiliary positioning for the upper mold core 14. Finally, the fixing component 22, in conjunction with the auxiliary positioning component 21, limits and fixes the upper mold core 14, thus improving the efficiency of replacing the upper mold core 14. By quickly replacing the lower mold core 12 and the upper mold core 14, it is easy to quickly replace worn lower and upper mold cores, indirectly improving production efficiency.
[0037] In some embodiments, the auxiliary positioning assembly 21 includes a rotary cylinder 211, a drive shaft 212, a driven shaft 213, an L-shaped plate 214, a slide rail 215, and a limiting rod 216. The rotary cylinder 211 is fixedly connected to the top of the upper mold frame 13, with its output end facing vertically upward and fixedly connected to the middle of the drive shaft 212. Both ends of the drive shaft 212 are hinged with driven shafts 213, and the opposite ends of the driven shafts 213 on both sides are hinged with L-shaped plates 216. 14. Two slide rails 215 are fixedly connected to both ends of the top of the upper mold frame 13. The L-shaped plates 214 on the left are fixedly connected to the sliders on the two slide rails 215 on the left, and the L-shaped plates 214 on the right are fixedly connected to the sliders on the two slide rails 215 on the right. The vertical sidewalls of the L-shaped plates 214 on both sides are symmetrically connected to limit rods 216. The ends of the limit rods 216 on both sides are respectively inserted into the corresponding limit grooves 141. Specifically, the end of the limit rod 216 on the left slides through the left side wall of the upper mold frame 13, extends into the tooling groove 131, and then inserts into the limit groove 141. The end of the limit rod 216 on the right slides through the right side wall of the upper mold frame 13, extends into the tooling groove 131, and then slides through the clearance groove 223 before inserting into the limit groove 141.
[0038] The fixing component 22 includes a drive cylinder 221 and a limiting block 222. The drive cylinder 221 is fixedly connected to the right end of the upper mold frame 13. The output end of the drive cylinder 221 slides through the right end of the upper mold frame 13 and extends into the tooling groove 131 and is fixedly connected to the limiting block 222. The limiting block 222 is slidably connected to the tooling groove 131. Both the front and rear side walls of the limiting block 222 are provided with clearance grooves 223 for avoiding the limiting rods 216. The two limiting rods 216 on the right side slide through the two clearance grooves 223 and are inserted into the corresponding limiting grooves 141.
[0039] In this invention, when the upper mold core 14 is placed inside the tooling slot 131, the output end of the rotary cylinder 211 drives the drive shaft 212 to move the driven shafts 213 on both sides inward. The two driven shafts 213 drive the limiting rods 216 to move inward through the L-shaped plate 214. The limiting rods 216 on the left and right sides are inserted into the corresponding limiting slots 141, thereby achieving auxiliary positioning of the limiting slots 141. At this time, the output end of the drive cylinder 221 drives the limiting block 222 to move the upper mold core 14 to the left along the limiting rod 216. When the left end of the upper mold core 14 is in contact with the inner wall of the left side of the tooling slot 131, the upper mold core 14 is limited and fixed, thereby achieving quick replacement of the upper mold core 14. The limiting rods 216 and the limiting block 222 provide support for the upper mold core 14, preventing the upper mold core 14 from shifting due to gravity and demolding force. When it is necessary to disassemble the upper mold core 14, the output end of the drive cylinder 221 drives the limit block 222 to move to the right and reset, and the output end of the rotary cylinder 211 drives the drive shaft 212 and the limit rod 216 to reset. The upper mold core 14 is disengaged from the tooling slot 131 under its own weight, which facilitates the quick replacement of the upper mold core 14.
[0040] In some embodiments, the disassembly and replacement mechanism 2 3 includes a drive cylinder 2 31, a limit block 2 32, a limit rod 2 33, a lifting cylinder 34, and a lifting block 35. The drive cylinder 2 31 is fixedly connected to the right end of the lower mold frame 11. The output end of the drive cylinder 2 31 slides through the right end of the lower mold frame 11 and extends into the tooling groove 2 111 and is fixedly connected to the limit block 2 32. The limit block 2 32 is slidably connected to the tooling groove 2 111. The front and rear ends of the left sidewall of the limit block 2 32 are fixedly connected to the limit rod 2 33. The two limit rods 2 33 are respectively inserted into the corresponding limit groove 2 121. The left end of the limit rod 2 33 is provided with a rounded corner to facilitate insertion into the limit groove 2 121. The bottom of the lower mold frame 11 is fixedly connected to the lifting cylinder 34. The output end of the lifting cylinder 34 slides through the bottom of the lower mold frame 11 and extends into the tooling groove 2 111 and is fixedly connected to the lifting block 35.
[0041] In this invention, the lower mold core 12 is placed inside the tooling groove 111. The output end of the driving cylinder 31 drives the limiting block 32 to move the limiting rod 33 to the left. The limiting rod 33 is inserted into the limiting groove 121. The limiting block 32 pushes the lower mold core 12 to move to the left. When the left side of the lower mold core 12 is in contact with the inner wall of the left side of the tooling groove 111, the lower mold core 12 is fixed. When the lower mold core 12 needs to be disassembled, the output end of the driving cylinder 31 drives the limiting block 32 and the limiting rod 33 to move to the right and reset, releasing the fixed position of the lower mold core 12. At this time, the output end of the lifting cylinder 34 drives the lifting block 35 to move the lower mold core 12 upward and disengage it from the tooling groove 111, which facilitates quick replacement of the lower mold core 12 and improves work efficiency.
[0042] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
