Description

Technical Field

[0001] The invention relates to the technical field related to injection molds, and more precisely to an inclined top milling fixture with adaptive safety length control. Background Art

[0002] Injection molds usually use ejectors or ejector blocks to eject products, and generally use a straight ejector to demold. When there are undercuts, bosses, or depressions in the mold, it is difficult to demold the product without damaging the product. In order to demold more easily without damaging the product, an inclined ejector can be used. The movement principle of the inclined ejector is to convert the vertical movement of the mold opening and closing into horizontal movement. When the mold is opened, the inclination angle of the inclined ejector can reduce the resistance during demolding. This method of demolding along the direction of the mold opening and closing can make the molded parts easily removed from the mold without causing damage to the parts, and has higher production efficiency.

[0003] In the commonly used inclined ejector standard, the inclination angle range is 1°-8°, the ejection formation range is 20-30mm, and the blank 100 processing length required by its product characteristics is generally 10-30mm. Figure 1 The figure shows a schematic diagram of an existing inclined top clamping method. When processing the inclined top forming part, the blank 100 is first placed on a pad 200 with an inclined surface on the top, and then a vernier caliper is used to measure the length of the front end of the blank 100 extending out of the front end of the pad 200 to ensure that the extended length of the blank 100 meets the processing requirements and is not longer than the safety length. After the measurement and adjustment are completed, manual pressure is required to maintain the extended length of the blank 100 unchanged, and at the same time, the jaws 300 of the flat-nose pliers are screwed in to clamp the blank 100 to complete the clamping of the blank 100.

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present 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 creative work are within the scope of protection of the present invention.

[0035] like Figures 2 to 4As shown, the present application provides an adaptive safety length controlled inclined top milling fixture comprising a clamping body 1, a clamping assembly 2 and a measuring assembly 3; a top side of the clamping body 1 has an inclined surface 101, and the clamping assembly 2 is installed on the inclined surface 101; the clamping assembly 2 clamps and fixes a blank 100, and a portion of the blank 100 extends out of the side of the clamping body 1; the measuring assembly 3 is telescopically installed in the clamping body 1, and the measuring assembly 3 and the blank 100 extend out of the same side of the clamping body 1, the measuring assembly 3 is butted against the end of the blank 100, and the extending length of the blank 100 is changed when the measuring assembly 3 is telescopically extended. The adjusting clamping component 2 can be adjusted to switch between clamping and loosening the blank 100, and the measuring component 3 can measure and adjust the length of the blank 100 extending out of the side of the clamp body 1. By operating the adjusting clamping component 2 and the measuring component 3, the extending length of the blank 100 can be quickly and accurately adjusted to meet the needs of processing and safe production, and the blank 100 can be fixed conveniently and quickly after the adjustment is completed for subsequent clamping and processing. The overall operation is convenient and fast, with higher work efficiency and better safety.

[0036] Specifically, the clamping assembly 2 includes an L-shaped pressing plate 21 and a side baffle 22. The L-shaped pressing plate 21 is inverted on the inclined surface 101. The side baffle 22 is installed on the inclined surface 101 and is parallel to the L-shaped pressing plate 21. The blank 100 is arranged between the L-shaped pressing plate 21 and the side baffle 22. The L-shaped pressing plate 21 blocks the top and one side of the blank 100, and the other side of the blank 100 is blocked by the side baffle 22. The side of the L-shaped pressing plate 21 has a plurality of fastening screws 212 that penetrate the L-shaped pressing plate 21. The fastening screws 212 can be rotated to adjust the fastening screws 212 to achieve the clamping or loosening of the blank 100. The fastening screws 212 can push the blank 100 toward the side baffle 22, so that the blank 100 is in close contact with the side baffle 22 and the inclined surface 101, thereby fixing the blank 100. The clamping assembly 2 is easy and quick to adjust, and can clamp the blank 100 without fixing it, which facilitates precise adjustment.

[0037] Specifically, the L-shaped pressing plate 21 is detachably connected to the inclined surface 101 through a fixing bolt 211 installed at the top, and the side baffle 22 is detachably connected to the inclined surface 101 through a fixing bolt 221 installed at the top. It is worth noting that for blanks 100 of different sizes, effective adaptation can be achieved by disassembling and replacing one or both of the L-shaped pressing plate 21 and the side baffle 22. The clamping assembly 2 has better adaptability to the blank 100, and the clamping assembly 2 can be conveniently replaced and adjusted to achieve processing requirements of different specifications.

[0038] See also Figure 4 and Figure 7The top of the clamp body 1 also has a plane 102, and the plane 102 is butted against the highest point of the inclined surface 101. Preferably, the plane 102 is lower than the highest point of the inclined surface 101, and sufficient space is reserved for the rear end of the blank 100 to prevent the blank 100 from colliding with the clamp body 1 and causing damage. Further, the height of the clamp body 1 is H, and preferably H is the sum of the height of the jaws 300 and the safety distance. The safety distance is determined according to specific processing requirements to ensure the safety of the processing operation.

[0039] The side of the clamp body 1 has a receiving groove 10 for the expansion and contraction of the measuring component 3, and the front of the clamp body 1 has an adjustment groove 11 for adjusting the measuring component 3, and the measuring component 3 can slide in the adjustment groove 11. Figure 3 to Figure 4 The measuring assembly 3 includes a slide 31 and a telescopic assembly 32. The slide 31 is slidably installed in the receiving groove 10 and the adjusting groove 11. The telescopic assembly 32 which can be adjusted in a direction perpendicular to the horizontal plane is installed on the top of the end of the slide 31 away from the receiving groove 10. The telescopic assembly 32 is used to dock with the end of the blank 100. When the slide 31 is retracted into the receiving groove 10, the telescopic assembly 32 is driven by the slide 31 to be retracted into the receiving groove 10. The bottom surface of the adjusting groove 11 has a slide rail 12. The slide 31 is slidably connected to the slide rail 12. The slide 31 is threadedly connected with a screw nut 315. The head of the screw nut 315 docks with the slide rail 12, and the tail is exposed in the adjusting groove 11. By rotating the screw nut 315, the locking state of the slide 31 and the slide rail 12 can be changed, and the sliding state of the switch slide 31 can be changed, so that it can be fixed, semi-fixed or smoothly slid, which is convenient for adjusting the measurement positioning.

[0040] Preferably, the screw-in nut 315 is installed at the end of the slide 31 away from the telescopic component 31, and the end of the slide rail 12 away from the telescopic component 31 has a locking screw hole 121. When the slide 31 is retracted to the inside of the accommodating groove 10, the screw-in nut 315 is aligned with the locking screw hole 121. When the screw-in nut 315 is screwed into the locking screw hole 121, the slide 31 and the slide rail 12 can be fixedly connected to prevent the measuring component 3 from slipping out during the processing to interfere with the processing operation or affect the processing safety.

[0041] The sliding ruler 31 has a scale 311 on the side of one end where the telescopic component 32 is installed. When the extended length of the blank 100 is adjusted by the measuring component 2, the extended length can be conveniently observed through the scale 311 to complete the adjustment operation conveniently and accurately.

[0042] See also Figure 5The slider 31 has a sliding engagement groove 312 extending along its central axis, and the sliding engagement groove 312 can be slidably engaged and mounted on the slide rail 12. The top of the slider 31 away from the receiving groove 10 has a mounting piece 313 for mounting the telescopic assembly 32, and the middle of the mounting piece 313 has a mounting through hole. The end of the slider 31 away from the telescopic assembly 32 has protruding limit bumps 310 on both sides, and the limit bumps 310 cooperate with the clamp body 1 to limit the extension length of the slider 31 to prevent the slider 31 from falling off when the extension length is too long.

[0043] See also Figure 6 and Figure 7 The side of the adjustment groove 11 is provided with a removable slide block 13, which is docked with the end of the slide rail 12 to block the slide 31 from sliding backward. After the slide block 13 is removed, the slide 31 can be easily replaced to replace the slide 31 of different lengths to meet different processing requirements. Preferably, the slide block 13 has protruding installation guides 131 on the upper and lower sides, and the two ends of the side of the adjustment groove 11 have recessed installation guides 111 respectively. The slide block 13 is inserted into the installation guide 111 through the installation guides 131, and can be easily pulled out and disassembled. Furthermore, the slide block 13 has a concave handle 132 on the side away from the slide rail 12, which further improves the convenience of the pulling operation, while ensuring the overall external flatness of the clamp body 1 to avoid interference with the clamping process.

[0044] See also Figure 8 and Fig. 9 The telescopic assembly 32 includes a telescopic fixing plate 321, a telescopic rod 322 and a locking nut 323. The telescopic fixing plate 321 is connected to the slide rule 31. The telescopic rod 322 is telescopically mounted on the top of the telescopic fixing plate 321. The locking nut 323 passes through the telescopic fixing plate 321 and docks with the telescopic rod 322. By rotating the locking nut 323, the locking state of the telescopic rod 322 can be changed to adjust the extension length of the telescopic rod 322 relative to the telescopic fixing plate 321. The top of the telescopic rod 322 has an L-shaped surface 3221. The blank 100 docks with the L-shaped surface 3221. The L-shaped surface 3221 supports the bottom and side of the end of the blank 100. Preferably, the inner corner of the L-shaped surface 3221 has a through hole 3222 to prevent the bottom corner of the blank 100 from being bumped, so as to ensure that the blank 100 is not damaged during the measurement and adjustment process.

[0045] The side of the telescopic rod 322 has an adjustment slot 3223, and the locking nut 323 is inserted into the adjustment slot 3223. The telescopic range of the telescopic rod 322 is limited by the cooperation between the adjustment slot 3223 and the locking nut 323. The side of the telescopic fixing plate 321 has a nut through hole 3213 for installing the locking nut 323. The cover plate 324 is installed on one side of the telescopic fixing plate 321 through a plurality of bolts 3241, and the telescopic fixing plate 321 has a telescopic cavity 3211 inside, and the telescopic rod 322 is installed in the telescopic cavity 3211. The telescopic cavity 3211 has an upper limit block 3214 extending inwardly, and the bottom two sides of the telescopic rod 322 have lower limit blocks 3224 respectively. When the telescopic rod 322 continues to move upward, the lower limit block 3224 contacts the upper limit hole 3214 to prevent the telescopic rod 322 from sliding upward and disengaging from the telescopic fixing plate 321.

[0046] The bottom of the telescopic fixing plate 321 has a fixing through hole 3212, and a mounting pin 325 is inserted through the fixing through hole 3212. The pin 325 is inserted and connected with the mounting through hole in the middle of the mounting member 313 to achieve a fixed connection between the telescopic fixing plate 321 and the mounting member 313. When disassembling and replacing, the pin 325 can be removed by a tool to replace the telescopic component of the corresponding size to adapt to different processing requirements.

[0047] See also Fig.10 When using the adaptive safety length controlled inclined top milling fixture of the present application, the bottom surface of the jaw 300 is set flush with the bottom of the clamp body 100, and the blank 100 with adjusted length is fixed by the clamping assembly 2, and the jaw 300 does not contact the blank 100.

[0048] See also Figures 11 to 15 When the self-adaptive safety length controlled inclined top milling fixture is used, first loosen the screw nut 313, and extend the slide rule 31 from the receiving groove 10 by operating the screw nut 313; then loosen the locking nut 323 to adjust the extension height of the telescopic rod 322; then loosen the fastening screw 212, insert the blank 100 between the side baffle 22 and the L-shaped pressing plate 21 in a manner of fitting the inclined surface 101 and the side baffle 22, and at the same time, dock the end of the blank 100 with the L-shaped surface 3221 of the telescopic rod 322; then, after ensuring that the blank 100 is in contact with the L-shaped surface 3221 of the telescopic rod 322, the end of the blank 100 is docked with the L-shaped surface 3221 of the telescopic rod 322. When the inclined surface 101 and the side baffle 22 are in contact with each other, the slide rule 31 is moved, and the extension height of the telescopic rod 322 is adjusted. After the adjustment is completed, the screw-in nut 313 and the locking nut 323 are tightened; then, the fastening screw 212 is tightened to fix the blank 100; then, the screw-in nut 313 and the locking nut 323 are loosened, the telescopic assembly 32 is contracted, and the locking nut 323 is tightened, and the slide rule 31 and the telescopic assembly 32 are stored in the accommodating groove 10, and finally, the screw-in nut 313 is screwed into the locking screw hole 121 again to complete the adjustment and clamping operation of the blank 100.
