Description

Technical Field

[0001] The invention relates to the technical field of mold guide pin sleeve maintenance and repair, and particularly discloses a rotation adjustment device for processing an injection mold guide pin sleeve. Background Art

[0002] A fundamental component of the guide pin sleeve is a stabilizing framework within each flap. This structure can be tightly bonded to the outer flap material through various processing methods. It is also applied to the bellows, maintaining its original shape even in high-temperature environments. Guide pin sleeves are a versatile product line, with materials, shapes, processing methods, and dimensions all customizable.

[0003] After searching, it was found that the application number is: CN201510865323.1, a rotation adjustment device for processing the guide pin sleeve of an injection mold, and its content is "The present invention discloses a rotation adjustment device for processing the guide pin sleeve of an injection mold, comprising a guide frame, a guide groove is provided on the guide frame, a mounting block is provided on the guide frame, a mounting block sleeve fixing pin is connected to the guide frame, a buckle cap is provided at the lower end of the fixing pin, the buckle cap is buckled at the bottom of the guide frame, the mounting block is provided with a slot, a rotating tube is inserted into the slot, a first connecting tube is provided at one end of the rotating tube, the first connecting tube is connected, a sleeve is provided at the end of the second connecting tube, a rotating ring is provided at the other end of the rotating tube, a rotating wheel is provided on the inward-facing surface of the rotating ring, the rotating wheel is sleeved on the outer circumferential surface of the rotating tube, a rotating disk is provided between the rotating ring and the rotating wheel, the rotating disk is sleeved on the outer circumferential surface of the rotating tube, and the outer circumferential surface of the rotating wheel is provided with an arc. The present invention facilitates the rotation heating treatment of the guide pin sleeve of the injection mold, and the heating is more uniform;

[0004] It should be added that this publicly available literature only serves as the rotation stage in thermoplastic processing. There is still a big difference between the two in terms of the specific fine clamping of the guide sleeve. Moreover, the subsequent quenching of the guide sleeve is very different in terms of whether adsorption or clamping trigger conditions are used. It does not involve the polishing, grinding and calibration detection of the guide sleeve.

[0005] Further searching revealed a high-precision polygonal linear guide post sleeve with application number CN202322299892.7, the content of which is as follows: The utility model discloses a high-precision polygonal linear guide post sleeve, comprising a guide post, the exterior of which is provided with a plurality of guide surfaces, and a sliding assembly fixedly sleeved on the exterior of the guide post through the guide surfaces, the exterior of the sliding assembly being sleeved with an outer sleeve, the exterior corners of the sliding assembly being fixedly provided with ribs, and the interior of the outer sleeve being provided with multi-faceted mounting holes. The utility model provides a sliding assembly, which includes a retaining frame and a needle roller, and the retaining frame, the guide surfaces, and the multi-faceted mounting holes are non-cylindrically matched, thereby limiting the rotation of the retaining frame between the outer sleeve and the guide post, thereby allowing the outer sleeve to be guided only along the central axis of the guide post through the retaining frame, effectively preventing sliding friction between the guide post and the outer sleeve and avoiding wear. At the same time, the sliding grooves on the outer sleeve and the ribs on the exterior of the retaining frame slide in cooperation, further improving the guide accuracy and service life. In addition, the following problems still exist:

[0006] The guide pin sleeve is usually divided into two sections: one with a space for the sleeve connection and the other with a solid narrow section, called guide pin sleeve A and the other guide pin sleeve B. The advantage of this is that the two molds are divided into a hollow area and a bolted area, which can make the two molds close smoothly as long as the guide pin sleeves are aligned and matched. However, the problem is that the hollow section of the guide pin sleeves of the two molds will deform after long-term use. There will be attachments blocking the inner wall, and wear caused by oil, dirt and impurities. In severe cases, the guide pin sleeve will cause deformation and need to be re-tempered and quenched for smooth alignment. In this process, there is no specific equipment to uniformly maintain and handle the two guide pin sleeves and then adjust and rotate them.

[0007] In addition, there is another difficulty in that the two types of guide pin sleeve structures are rotated uniformly and then tempered uniformly, which has a low degree of integration. For manufacturers who only use molds and do not manufacture molds, the guide pin sleeves of this type of mold are inserted and pulled out for a long time. After long-term wear, the mold edge closing effect and alignment effect are reduced. Later, they need to be returned to the factory, which wastes time. It is better to have equipment to clamp the guide pin sleeves and temper them in a small workshop. The overall process can be assisted by personnel to solve the quenching correction (lathes or other polishing calibration equipment can be used). Integrated quenching, quenching oil immersion and polishing are integrated equipment.

[0008] For example, in the later stage of quenching, various equipment are maintained, unified clamping and matching electromagnet adsorption are carried out, and a series of fine calibration problems are observed, because the guide pin sleeve processing is nothing more than removing the guide sleeve that has been used for a long time from the injection mold to clean up some attachments left over from the production, and tempering and quenching it at the same time. After adding some compensating catalysts from quenching and smelting, the remaining gaps on the surface of the guide pin sleeve are repaired, and then calibrated and polished, and some small repair processes are carried out. In addition, whether it is the integration of use or the later repair of the injection mold guide pin sleeve, as long as it plays a corresponding convenient maintenance role, it is urgently needed at this stage. Whether it is queuing for quenching oil immersion or high-temperature quenching similar to the rotation scheme, it is urgent to be solved, and specifically strive to achieve the requirements of low-cost quenching of the guide pin sleeve, which is suitable for the guide pin sleeve maintenance problems of only mold application but not mold manufacturers.

[0046] Beneficial effects:

[0047] 1) From a macro perspective, the injection mold guide pin sleeve gripping mechanism is used to process and rotate the structure of the guide pin sleeve that needs to be processed. The quenching mechanism used can transfer the mechanism to the quenching object, that is, the outside of the guide pin sleeve, at any time when the injection mold guide pin sleeve structure needs quenching maintenance. After the sealing cover is connected, the quenching is completed. It is also necessary to add a quenching catalyst during quenching. Therefore, the spray gun mechanism used in the macro sprays the quenching medium on the outer wall of the quenched red guide pin sleeve. After heating, the notch or damaged part on the surface of the guide pin sleeve is repaired and the depression is filled at high temperature. In order to facilitate the adaptation of the quenching box position change, the structure of the maintenance conversion mechanism is combined to realize the forward and backward movement of the quenching structure. In addition, oil immersion quenching and subsequent polishing after quenching are also indispensable processing methods. These are integrated to achieve scale miniaturization. For each group of molds that need to be maintained, it is convenient for mold maintenance for mold molding manufacturers to save the complexity and tediousness of returning the mold to the factory for repair. In the conversion stage, there are two conversion processing solutions for guide pin sleeve parts B and guide pin sleeve parts A.

[0048] 2) From a microscopic perspective, the sliding rod, linear guide rail, and angle adjustment shaft are used to articulate the arc-shaped bracket that is triggered by pushing forward and backward along the linear guide rail. The arc-shaped brackets on both sides simulate the open or closed state of the crab claws. When opened, the clamping paddles are pressed against the inner wall of the guide post sleeve part A to ensure embedded clamping and prevent loosening. The other guide post sleeve part B is attached and adsorbed using an electromagnet assembly seat, electromagnet, and adsorption slot. The clamping is maintained by the connecting rod and the arc-shaped clamps on both sides, combined with the elastic rubber buffer clamping. This prevents the electromagnet from losing its magnetic force during high-temperature quenching, and the arc-shaped clamps are used to maintain the clamping solution.

[0049] The angle conversion method uses the rotation of two pairs of stators and rotors to gradually adjust the rotation of two guide sleeves of different specifications in combination with the rotation of the rotor. In addition, during the rotation stage of one end of the magnet, the internal structure of the adsorption slot is kept rotating while the outer electromagnet assembly seat remains stationary.

[0050] 3) The axial flip structure of the angle conversion motor, shaft sleeve and rotary adjustment seat ensures that the guide pillar sleeves set on both sides can be placed at the quenching end. The gas is input through the branched arc gas pipe, and then the corresponding flames are gradually ejected by multiple independent flame heads. These flames are evenly distributed in the quenching box. Just like barbecue skewers, the rotor and stator in the motors at both ends are driven respectively to drive the guide pillar sleeve parts A and guide pillar sleeve parts B to rotate, and the temperature is evenly increased to complete high-temperature quenching. In addition, the gas is input from the gas storage tank and gas pipe. The catalyst spray after quenching is sprayed by the holding gun and the spray gun. The quenching medium, such as catalytic carbon quenching iron chips, molten salt carbon material mixture, is sprayed on the red-hot guide pillar sleeve to complete the catalysis, and finally the high-temperature quenching is followed;

[0051] 4) Starting from the refinement aspect, the quenching oil quenching after quenching is transferred with tweezers and placed on the surface of the suspension link in a triangular layout. The pneumatic cylinder drives the lifting and lowering of each independent guide pin sleeve to be catalyzed. After being automatically placed according to the drive motor, it is soaked with quenching oil and then quenched, which improves the quenching efficiency and eliminates the original raw material waste left over from long-term use. After repeated annealing and tempering, it is gradually cooled to eliminate the residual material on the surface of the injection mold guide pin sleeve after long-term use, thereby improving the maintenance effect of the guide pin sleeve;

[0052] 5) From a microscopic perspective, when the polishing motor in the technology is used and the polishing roller on its surface is driven, a polishing frosted belt is applied to the external sleeve according to the axial rotation state of the polishing roller. For the injection mold guide pin sleeve that has been quenched many times and needs to be polished, the surface burrs can be kept fewer and more delicate, and the outside of the guide pin sleeve remains smooth. Finally, because the quality of the finished product cannot be seen by the naked eye during the quenching stage quality inspection, the articulated display seat and the magnifying probe can be used to image it, and then the feedback can be displayed on the display panel. In order to highlight the overall advantage in size, the structure is as compact as possible, so that after the injection mold guide sleeve is worn, it can be tempered and quenched in time for maintenance, thereby increasing the service life of the guide pin sleeve.

[0086] The present application will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely for the purpose of explaining the relevant invention and are not intended to limit the invention. It should also be noted that, for ease of description, only portions relevant to the invention are shown in the accompanying drawings.

[0087] The drawings in the embodiments of the present invention: Different types of section lines in the drawings are not marked according to national standards, nor do they impose any requirements on the materials of the components. Instead, they are used to distinguish the cross-sectional views of the components in the drawings.

[0088] See also Figure 1 - Figure 17, a rotary adjustment device for processing injection mold guide pin sleeves:

[0089] Example 1:

[0090] Please refer to the instruction manual Figure 1 - Figure 3 As shown:

[0091] It includes an injection mold guide pin sleeve grasping mechanism 1, a carrying mechanism 2 and a maintenance conversion mechanism 3;

[0092] The injection mold guide pin sleeve gripping mechanism 1 is used to grip the object to be processed;

[0093] The carrying mechanism 2 is used to support each processing unit;

[0094] The maintenance conversion mechanism 3 implements maintenance processing on the object grasped by the injection mold guide pin sleeve grasping mechanism 1;

[0095] The supporting mechanism 2 includes a supporting base 21, a pad 22 is connected to the edge of the supporting base 21, and a pull-out plate 23 for receiving processing debris is connected to the other end of the supporting base 21, and a receiving slot 24 is opened on the surface of the pull-out plate 23;

[0096] The injection mold guide pin sleeve gripping mechanism 1 includes a linear slide rail 11 connected to the top surface of a support base 21, an L-shaped bracket 12 is installed in the middle of the top of the linear slide rail 11, and a rotary adjustment seat 121 is provided at the inclined end of the L-shaped bracket 12. An angle conversion motor 122 for angle conversion is installed at the top of the rotary adjustment seat 121. The output end of the angle conversion motor 122 is connected to a sleeve 123 in the direction of the displacer. A bidirectional rotation motor 13 is embedded in the middle of the sleeve 123. The bidirectional rotation motor 13 consists of two oppositely arranged stators 131 and two independently rotating rotors 132.

[0097] When used specifically, step one: requires a convenient combination of processing components;

[0098] The first assembly stage is to first extend the plate surface of the pull-out plate 23 based on the side according to the support base 21 to ensure the designated support base 21 and the subsequent pull-out plate 23, and then stretch it. In the processing stage, the expansion range is larger, and the quenching can be better carried out to receive the groove 24;

[0099] After that, the linear slide rail 11 is used to control the forward and backward sliding displacement of the L-shaped bracket 12, so as to replace the upper half of the guide column sleeve gripping mechanism 1 of the injection mold. At this time, the user can insert the through groove 163 opened on the side wall of the guide column sleeve part A16 into the right side. In order to fix it, the user needs to turn on the electric push rod 153. The output end will pull the arc trigger gasket 154 to slide back and forth along the linear slide rail 152, so that the movable joint bracket 1542 it mobilizes moves synchronously. When the hinged movement is performed, the movable joint bracket 1542 is hinged around the surface of the angle adjustment shaft 1543. At this time, the arc bracket 1544 will be hinged with the corresponding angle adjustment shaft 1543 due to the change of position, and the arc bracket 1544 will be adjusted to expand and clamp with the inner wall support of the annular groove 161. At this time, the pulling spring 1547 is pulled to facilitate the later expansion.

[0100] Finally, clamping is completed;

[0101] Example 2:

[0102] Please refer to the instruction manual Figure 4 - Figure 9 As shown: In this embodiment: the two stators 131 are symmetrically fixedly connected, and the rotating ends of the two rotors 132 are respectively installed with an electromagnetic adsorption structure 14 and a sliding clamping structure 15;

[0103] One side of the two stators 131 is fixedly mounted to the shaft sleeve 123;

[0104] The electromagnetic adsorption structure 14 includes an electromagnet assembly seat 141 connected to the left rotor 132. A power adjustment line 142 is installed at the bottom of the electromagnet assembly seat 141. A power regulator 143 is installed at the end of the power adjustment line 142. A power adjustment knob 144 is installed on the surface of the power regulator 143.

[0105] An electromagnet 145 is mounted on the side of the electromagnet assembly seat 141, and an adsorption groove 146 is provided on the magnetic adsorption end of the electromagnet 145;

[0106] The power adjustment knob 144 is electrically controlled by the power regulator 143 and the electromagnet 145 .

[0107] The power regulator 143 is used to change the magnetic strength of the electromagnet 145 and the inner wall of the adsorption slot 146. In order to avoid rotation problems, the embedded structure of the adsorption slot 146 rotates while the main body of the electromagnet 145 on the outside is magnetically attracted and remains stationary.

[0108] In this embodiment: a connecting rod A1451 is also installed on the edge of the electromagnet 145, and elastic torsion spring shafts 1452 are symmetrically installed on the outer walls of both sides of the rod body of the connecting rod A1451. The rotating end of the elastic torsion spring shaft 1452 is installed with an arc clamp 1453, and the ends of the two arc clamps 1453 are both installed with elastic rubber 1454.

[0109] The elastic torsion spring shaft 1452 is mainly based on the consideration of the situation that the magnetic force fades and weakens during a part of the high-temperature heating stage. In this case, the elastic torsion spring shaft 1452 and the arc clamp 1453 are used to complete the object clamping. In addition, the quenching rotation is also to maintain the magnetic adhesion solution adsorption and slow rotation. For demagnetization, an alternative solution is used, and some clamping structures are added using the electromagnet 145, and mechanical drive is used to avoid demagnetization defects.

[0110] In this embodiment, a slide rod 151 is installed at the end of the rotor 132 on the right side. A linear slide rail 152 is installed on the top of the slide rod 151. An electric push rod 153 is installed on the edge of the track surface of the linear slide rail 152. The telescopic end of the electric push rod 153 pulls an arc-shaped trigger gasket 154.

[0111] The inner wall of the arc-shaped trigger gasket 154 cooperates with the slider structure of the linear slide rail 152;

[0112] The inner edges of the arc-shaped trigger gasket 154 are hinged with a coordination shaft 1541. A movable joint bracket 1542 is installed at the bottom of the coordination shaft 1541. The middle of the movable joint bracket 1542 is connected to an angle adjustment shaft 1543. One end of the angle adjustment shaft 1543 is mounted with a curved bracket 1544 for shifting. The two edges of the curved bracket 1544 are respectively and sequentially mounted with a plurality of independent clamping paddles 1545.

[0113] A spring hook ring 1546 is provided in the arc region of the arc bracket 1544 , and a pulling spring 1547 is installed at the end of the spring hook ring 1546 , and the other end of the pulling spring 1547 is fixedly installed on the outer wall of the tube of the slide rod 151 .

[0114] The pulling spring 1547 and the spring hook ring 1546 ensure that the displacement of the clamped arc-shaped trigger gasket 154 is automatically reset, similar to the elastic trigger scheme of a crossbow bow, and has great freedom of control.

[0115] The outer wall of the two arc-shaped brackets 1544 is elastically clamped with a guide post sleeve part A16. The edge of the guide post sleeve part A16 is provided with a plurality of annular grooves 161. The outer wall edge of the guide post sleeve part A16 is fitted with a convex ring 162.

[0116] A through slot 163 is formed in the middle of the guide pin sleeve part A16, and the through slot 163 is clamped with the outer wall of the arc-shaped bracket 1544;

[0117] A guide pin sleeve part B17 is magnetically adsorbed on the surface of the adsorption groove 146;

[0118] One end surface of the guide pin sleeve part B17 is magnetically connected to the adsorption groove 146;

[0119] A buffer guide post 171 is installed on the other end of the guide post sleeve part B17. A buffer steel spring 172 is sleeved on the surface of the buffer guide post 171. The other pressure-bearing end of the buffer steel spring 172 is supported and connected to the guide post sleeve seat 173.

[0120] The elastic support ends of the two elastic rubbers 1454 are tightly bound to the elastic clamps of the guide column sleeve part B17.

[0121] Guide pin sleeve part B17 and guide pin sleeve part A16 are two different accessories used in mold guide pin sleeves. These two accessories are set-up solutions. Based on the two different characteristics of one being a solid pipe and the other being a hollow pipe, they are clamped separately. In addition, to solve the problem of high-temperature demagnetization, the elastic clamping structure is considered to be used to clamp this structure so that it can rotate freely.

[0122] The maintenance conversion mechanism 3 includes a multi-joint mounting base 31 mounted on the top of the support base 21. A rotating shaft 32 is mounted on the top of the multi-joint mounting base 31. A tapered sleeve 33 is mounted in the middle of the top. A first movable joint 34 is mounted on the side of the tapered sleeve 33. A first movable link 35 is mounted in the middle of the top of the first movable joint 34. A second movable joint 36 is provided at the top of the first movable link 35. A second movable link 37 is provided at one end of the second movable joint 36.

[0123] Step 2: The coordinated guide pin sleeve part B17 is assembled in the adsorption groove 146 area for clamping;

[0124] After the adsorption is completed, the personnel operate the power regulator 143 to strengthen the adsorption capacity. At this time, the power adjustment knob 144 is manually adjusted to the maximum value. In this way, the magnetic force of the electromagnet assembly seat 141 is enhanced, and the guide column sleeve part B17 is gradually adsorbed and clamped. In order to avoid the adsorption stage being unstable;

[0125] Therefore, the linkage stage of the connecting rod A1451 and the clamping stage of the arc clamp 1453 can utilize the hinged state of the elastic torsion spring shaft 1452 to implement the connection structure for fixation and clamping on the outer wall of the guide column sleeve part B17;

[0126] Step 3: Change the angles of the guide post sleeve part B17 and the guide post sleeve part A16 to achieve the transformation;

[0127] Based on the fact that the angle conversion motor 122 is restricted by the rotation axis and fixed to the top of the L-shaped bracket 12, the angle conversion motor 122 drives the shaft sleeve 123 structure to change the direction to the end required according to the needs;

[0128] Step 4: Hinged flip of the guide column sleeve;

[0129] The corresponding joints are adjusted by rotating the multi-joint mounting base 31 and the top rotating shaft 32 until the position of the quenching mechanism 4 is changed. The appropriate position is maintained. The quenching box 41 is gradually pushed into the outside of the guide column sleeve part B17 according to the designated position after the first movable link 35 and the second movable joint 36 are articulated. After the coating is completed, the electric high-temperature quenching gas is finally turned on to inject. Either side of the guide column sleeve inserted into the quenching box 41 can be adjusted because the middle side can be driven by the motor to turn.

[0130] When quenching is required, the combustible gas stored in the gas storage tank 44 is used. The combustible gas moves along the position of the gas pipe 45 and is finally introduced into the corresponding three independent arc-shaped gas pipes 42. When the gas is extended, the branched flame head 43 will spray the gas into the quenching box 41.

[0131] At this time, both guide pin sleeve part B17 and guide pin sleeve part A16 are directly sprayed by high-temperature flames, heating up and turning red. The purpose of this is to prepare for the subsequent quenching by adding quenching oil and sprinkling carbon quenching medium. The purpose is also very clear, that is, some guide pin sleeve parts that have been used for a long time have too many impurities and aging layers attached to them, so they can be re-tempered and forged again to extend the service life of the mold guide pin sleeve. Some impurities or stubborn attachments on the surface are removed by high temperature, leaving opportunities for forging in the later stage.

[0132] Secondly, it is also for some small factories that are not independent manufacturers of injection molds and those engaged in mold processing, so that they can buy back the device to use and maintain the guide pin sleeve on the original mold, which is convenient for small-scale enterprises to carry out maintenance;

[0133] In order to avoid demagnetization due to high temperature, the angle adjustment shaft 1543 and the elastic torsion spring shaft 1452 can also be successfully clamped to the outer wall of the guide column sleeve part B17;

[0134] After waiting for a while, manually adjust the rod position of the second movable link 37 backward so that the guide pillar sleeve that has been processed and heated can be displayed;

[0135] Example 3:

[0136] Please refer to the instruction manual Figure 10 - Figure 11 As shown:

[0137] A spray gun mechanism 8 for regulating the spraying of the quenching carbon material is provided near the side of the support base 21;

[0138] The spray gun mechanism 8 includes a holding spray gun 81 hung on the surface of the connecting rod B54, and a nozzle 82 for conveying quenching carbon material is provided on the top side of the holding spray gun 81.

[0139] The gripping spray gun 81 is used to emit a quenching catalyst, a carbon material or a quenching oil.

[0140] Step 5: Sprinkle the carbon material or quenching material used for quenching;

[0141] The personnel hold the spray gun 81 and remove it from the position of the connecting rod B54, then fill it with the quenching medium raw material and press it with gas (external air pump). After pressing, the material is sprayed directly from the nozzle 82 to the nozzle on the high-temperature quenching like spraying paint. During quenching, the catalyst can be smoothly added to accelerate the quenching reaction.

[0142] During the quenching stage, the combustion is uniform, and the two rotors 132 are used to drive the guide column sleeve part B17 and the guide column sleeve part A16 to rotate separately around the shaft sleeve 123 while the clamp sleeve is tightened;

[0143] This does not affect the overall rotation of the shaft sleeve 123 driven by the angle conversion motor 122; in this way, after the guide pin sleeve part B17 at one end is processed, the guide pin sleeve part A16 is then quenched in the conversion direction;

[0144] Example 4:

[0145] Please refer to the instruction manual Figure 12 - Figure 14 As shown: In this embodiment: a quenching mechanism 4 is installed on the top of the rod body of the second movable link 37;

[0146] The quenching mechanism 4 includes a quenching box 41 mounted on the outer wall of the second movable link 37. The quenching box 41 is surrounded by arc-shaped gas pipes 42. Several arc-shaped gas pipes 42 are embedded in the pipe heads of each of the pipes to output gas. The outlets of the several flame heads 43 are arranged in sequence around the inner wall of the quenching box 41.

[0147] A gas storage tank 44 is installed on the side of the first movable joint 34 , and the outer wall of the gas storage tank 44 is sealed and connected to the corresponding arc-shaped gas pipes 42 through the connected gas pipes 45 .

[0148] Based on the arc-shaped gas pipe 42, the heat treatment quenching is carried out from the pipeline to the distributed flame head 43, forming a spatial high-temperature quenching trigger of the quenching box 41. In addition, both sides of the quenching box 41 are hollowed out, and the flame and oxygen remain through.

[0149] An oil immersion mechanism 6 is mounted on the sidewall edge of the support base 21. The oil immersion mechanism 6 comprises an arc-shaped support frame 61 for support. An oil immersion tank 62 is mounted in the middle of the top of the arc-shaped support frame 61. An oil delivery slot 63 for delivering oil is provided in the middle of the top of the oil immersion tank 62. A suspension link 64 for placing the guide column sleeve to be immersed is mounted in the middle of the top of the oil delivery slot 63. Rotating disks 65 are provided at both ends of the suspension link 64. A check shaft 66 for check assembly is mounted at the bottom of the rotating disk 65.

[0150] A driving motor 67 is installed at the bottom of the rotating disk 65 , and a pneumatic cylinder 68 is installed at the bottom of the driving motor 67 . The telescopic end of the pneumatic cylinder 68 is telescopically arranged with the bottom of the driving motor 67 .

[0151] The driving motor 67 changes the angle of the rotating disk 65, and the pneumatic cylinder 68 is used to change the height of the suspension link 64 for the purpose of supporting placement, so that the guide column sleeve can always be deeply inserted into the oil delivery slot 63 for infiltration and oil quenching.

[0152] The side of the support base 21 is further provided with a polishing mechanism 7, which includes a polishing seat 71 mounted on the side wall of the support base 21. A polishing motor 72 is mounted on the side wall of the polishing seat 71. The output end of the polishing motor 72 is connected to a polishing roller 73. A side wall baffle 74 is obliquely mounted on the middle part of the top end of the polishing roller 73.

[0153] The polishing roller 73 is meshed with the output end of the polishing motor 72 via a gear set.

[0154] The polishing roller 73 and the side wall baffle 74 are both designed to facilitate the addition of a frosted grinding wheel or frosted belt to shave off excess burrs to make the outer wall of the guide column sleeve smoother and have a frosted texture. Multiple devices are integrated and coordinated together. The main purpose is to simplify the time for equipment switching and make the processing links more organized and prioritized.

[0155] Step 6: Oil infiltration after quenching;

[0156] In this process, the quenching box 41 is dislocated, and the structure is then turned outward and placed in the receiving slot 24, eliminating the gap between the two arc-shaped brackets 1544. In this way, the red-hot guide post sleeve parts A16 are manually removed with tweezers (after being clamped and stacked separately). Then, tweezers are used to place them in batches on the surface of the suspension link 64. This is equivalent to a hanging rack structure. Both the guide post sleeve parts A16 and the guide post sleeve parts B17 can be clamped and placed on the end of this suspension link 64 because there is an opening reserved in the middle of this port. After rotation, the rod body extends downward and hangs in the air.

[0157] Stack well;

[0158] Start the drive motor 67 to drive the check shaft 66 and the rotating disk 65 to rotate in unison, so that each suspension link 64 will have the opportunity to place the oil-quenched guide column sleeve into the immersion oil tank 62, and use the pneumatic pressure cylinder 68 to lift or perfectly solve the problem of placing or immersing the guide column sleeve into the quenching oil to achieve quenching and cooling;

[0159] After quenching, it can be cooled and polished later;

[0160] The entire process of rotating the mold guide pin sleeve is completed;

[0161] Each part is immersed and then waited for 20-30 minutes before adjusting the position and hanging;

[0162] Tempering again, so-called tempering is: putting the flame head 43 back to its original position and spraying it again;

[0163] After the fire is sprayed, the operation is repeated 2-3 times, quenching, spraying the quenching medium, and then immersing in the quenching oil;

[0164] Finally, cool it down and polish it after cleaning;

[0165] Because considering that the surface of some parts is relatively rough during the quenching stage and some quenching materials remain, some parts are required to make up for the smoother surface characteristics of the parts during the quenching stage;

[0166] The polishing motor 72 in the polishing mechanism 7 drives the polishing roller 73 to rotate, and then the polishing belt driven by the polishing roller 73 rotates, and the guide pin sleeve, whether A or B (after cooling), is placed on the polishing roller 73 driven by high-speed rotation for polishing;

[0167] Example 5:

[0168] Please refer to the instruction manual Figure 15 - Figure 17 As shown: a quality inspection mechanism 5 is also installed in the middle of the support base 21;

[0169] The quality inspection mechanism 5 includes an L-shaped toggle frame 51 installed in the middle of the top of the support base 21. The end of the L-shaped toggle frame 51 is hinged with a linkage roller 52. One end of the linkage roller 52 is connected to a connecting rod B54. The top of the connecting rod B54 is installed with a rotating shaft 55 for flipping and hinged connection. The top of the rotating shaft 55 is provided with a concave bracket 56. The middle of the concave bracket 56 is elastically connected to a buffer spring 57. The top of the buffer spring 57 is elastically pulled with the middle of the rotating shaft 55.

[0170] A hinged protrusion 58 is installed at the top of the rotating shaft 55. The top of the hinged protrusion 58 pulls an elastic buffer structure 59. A frame 591 is provided at the end of the elastic buffer structure 59. The end of the frame 591 is hinged with a linkage roller 592.

[0171] The purpose of the quality inspection mechanism 5 is to perform refined flaw detection by magnification, with some changes in the position of the searchlight 594 or the magnifying probe 595 maintained by the elastic buffer structure 59 and the frame 591.

[0172] In this embodiment, a U-shaped bracket 593 is mounted on one end of the linkage roller 592, a searchlight 594 is mounted on the end of the U-shaped bracket 593, a magnifying probe 595 for detailed magnification is mounted on the side of the searchlight 594, and a control knob 596 is mounted on the top of the magnifying probe 595;

[0173] A display screen bracket 597 for supporting is provided at one end of the searchlight 594 , a hinged display base 598 is installed at the top end of the display screen bracket 597 , and a display panel 599 is installed at the middle of the top end of the hinged display base 598 .

[0174] Searchlight 594 is used to increase the brightness of the flaw detection magnification process, and the flaw detection is based on display feedback, ensuring that some corrections to inadequate polishing during the flaw detection process are accurately obtained during the polishing stage.

[0175] After polishing, clean it. After cleaning, take a photo to identify the corresponding record.

[0176] Step 7: Take a photo, increase the brightness and check again;

[0177] Then, the hinged shaft 55 is used to gradually move downward during the axial rotation and swinging stage by utilizing the deflection of the hinged protrusion 58. During the downward movement stage, the searchlight 594 is regulated to move downward, and after being turned on, it emits light to increase the surrounding brightness. Based on the detection aspect of the amplified probe 595, the area recorded by the probe is observed according to the area feedback of the display panel 599 and displayed on the surface of the display panel 599.
