Description

Technical Field

[0001] The invention relates to the technical field of injection molding, and in particular to an injection mold lifting and carrying system for a plastic injection molding machine. Background Art

[0002] Injection molds are tools for producing plastic products; they are also tools that give plastic products complete structures and precise dimensions. Although the structure of injection molds may vary due to differences in plastic types and properties, the shape and structure of plastic products, and the type of injection machine, the basic structure is the same. Generally speaking, a single injection mold is heavy, so the safety and convenience of mold storage are particularly important. In addition, since injection molds are very precise in manufacturing accuracy and are expensive, in order to protect the molds from accidental damage, dedicated mold racks are usually used to place idle molds. The height of the multi-layer mold placement rack is relatively high. Since the molds are relatively heavy, it is difficult to carry them when placed at a high level, and there are certain safety hazards.

[0003] The lifting work platform is a multifunctional lifting mechanical equipment, which can be divided into fixed and mobile, guide rail, crank arm, scissor type, chain type, loading and unloading platform, etc. The existing lift is not convenient for vertical lifting and transportation of injection molds. In the existing patent announcement number CN207224445U, a lifting and transportation device for injection molds used in plastic injection molding machines is disclosed, including a base frame, a first adjustment frame and a second adjustment frame are arranged on both sides of the base frame, a first bottom tube is arranged at the lower part of the second adjustment frame, the upper end of the first bottom tube is connected to the lower part of the second adjustment frame, a moving wheel is arranged at the lower end of the first bottom tube, a docking shaft is arranged between the middle parts of the first adjustment frame and the second adjustment frame, a docking pipe is arranged between the lower parts of the first adjustment frame and the second adjustment frame, a lifting seat is arranged between the tops of the first adjustment frame and the second adjustment frame, hydraulic cylinders are arranged on both ends of the docking pipe, a piston rod is arranged at the upper part of the hydraulic cylinder, the lower end of the piston rod is connected to the upper part of the hydraulic cylinder, a lifting pipe is arranged between the upper ends of the piston rod, and the lifting pipe is installed between the upper parts of the second adjustment frame.

[0004] In the above technical solution, the injection mold can be lifted and transported vertically by the lifting and transporting device. However, when the mold rack needs to be placed at a high place, the lifting height of the device is relatively low, which is not convenient for transporting the mold at a high place.

[0047] See also Figure 1-11 The present invention provides a technical solution: a lifting and transporting system for injection molds of a plastic injection molding machine, comprising a lifting body 1, the lifting body 1 including a lifting plate 3, a placement opening 104 is provided on the lower side of the lifting body 1, a plate outlet groove 107 is provided at the lower end of the placement opening 104, the plate outlet groove 107 is matched with the lifting plate 3, the lifting plate 3 passes through the plate outlet groove 107 and is horizontally displaced to the outside of the lifting body 1 to receive the mold body, the upper end of the placement opening 104 is hingedly connected with a closed door 105, and the closed door 105 is matched with the placement opening 104;

[0048] The closed door 105 is set to be a magnetic metal, a magnet block 9 is set on the upper side of the closed door 105, the lifting body 1 is fixedly connected to the magnet block 9, and a magnet block 2 is similarly set on the inner side of the base 4;

[0049] Linear drive mechanisms are provided on both sides of the lifting plate 3, and the linear drive mechanisms drive the lifting plate 3 to rise and fall;

[0050] The lifting body 1 further includes four vertical support plates 106, the lower ends of the vertical support plates 106 are fixedly connected to the base 4, and the upper ends of the vertical support plates 106 are fixedly connected to the upper plate 101;

[0051] The linear drive mechanism includes a pair of threaded rods 401, the threaded rods 401 are rotatably connected to the upper end of the base 4, the upper end of the threaded rods 401 is rotatably connected to the upper plate 101, a pair of long grooves 301 are passed through the two ends of the lifting plate 3, the threaded rods 401 pass through the long grooves 301, the threaded rods 401 pass through and are threadedly connected with an internal thread seat 402, a reinforcing rod 403 is provided on one side of the internal thread seat 402, the upper end of the reinforcing rod 403 is hingedly connected to a hinge seat, the hinge seat is fixed to the lower end of the lifting plate 3, an adaption groove 404 is provided on the inner side of the base 4, and the reinforcing rod 403 is inclined to the threaded rod 401 in the initial state;

[0052] A pair of horizontal plates 302 are slidably matched at both ends of the lifting plate 3. A groove is opened at one end of the horizontal plate 302. The groove is adapted to and slidably matched with the lifting plate 3. The pair of horizontal plates 302 are slidably matched with the vertical support plate 106. The threaded rod 401 passes through the horizontal plate 302 and is gap-matched with it.

[0053] In the initial state, the lifting plate 3 is at the lowermost end of the inner side of the lifting body 1 (such as Figure 2 As shown), this height is convenient for taking or placing the mold body, and improves the comfort of use. When the mold body needs to be placed, the lifting plate 3 is moved horizontally, thereby extending to the outside of the lifting body 1, so that the staff can manually or use the driving mechanism to place the mold body on the lifting plate 3, and then the lifting plate 3 is reset to the inside of the lifting body 1, and then the lifting plate 3 is driven by the linear drive mechanism to move up and down. The linear drive mechanism includes but is not limited to the use of a lead screw mechanism, a gear rack mechanism, etc., so as to drive the mold body to move to a position of any height. Similarly, when the mold body needs to be removed, the lifting plate 3 is brought down and extends out of the outside of the lifting body 1, so that it is convenient for the staff to take it, and there is no need to manually carry or use a driving mechanism to store or take mold bodies of different heights, thereby improving convenience and safety;

[0054] A placement opening 104 and a plate outlet slot 107 are provided, so that the lifting plate 3 can be moved to extend to the outside of the lifting body 1 and access the mold body, and a closed door 105 is provided. In the initial state, the closed door 105 closes the placement opening 104 and the plate outlet slot 107 to prevent dust from entering the lifting body 1, and a magnet block 2 is provided to adsorb and fix the closed door 105 to improve the stability of the closure. When it needs to be opened, the staff pulls the closed door 105 to flip it upward until it is adsorbed with the magnet block 1 9, so that the closed door 105 can be fixed and kept in an open state, which is convenient for entering or removing the mold body;

[0055] Preferably, in order to improve the stability of the horizontal movement of the lifting plate 3, a pair of horizontal plates 302 are provided, the lifting plate 3 is inserted into the groove of the horizontal plates 302 and slides against each other, the horizontal plates 302 can only slide up and down along the vertical support plates 106, and the lifting plate 3 slides relative to the horizontal plates 106, thereby improving the stability of the horizontal displacement of the lifting plate 3;

[0056] Preferably, since some large molds have a large weight, when the lifting plate 3 is extended to the lifting body 1, its lower side lacks support, and it is difficult to stably support the mold body only by the horizontal plate 302. Long-term use can easily cause the center of gravity to shift, resulting in the lifting plate 3 breaking and the mold body falling, causing a safety accident. Therefore, a reinforcing rod 403 is also provided. Specifically, a hinge seat is provided on the lower side of the end of the lifting plate 3 close to the outlet, and the lower end of the hinge seat is hingedly connected to the reinforcing rod 403. The lower end of the reinforcing rod 403 is provided with an internal threaded seat 402. When it is necessary to drive the lifting plate 3 to move out of the lifting body 1, a motor assembly is provided inside the base 4 to drive the threaded rod 401 to rotate, and the threaded rod 401 drives the internal threaded seat 402 to move upward. Since the reinforcing rod 403 is inclined to the threaded rod 403 in the initial state 401, so when the internal thread seat 402 moves upward, the tilt angle is gradually enlarged, thereby pushing the hinge seat and the lifting plate 3 to move outward until the other end of the long groove 301 contacts the threaded rod 1 401, and the movement is completed. At this time, since the internal thread seat 402 is threadedly connected with the threaded rod 1 401, the internal thread seat 402 maintains the current position and does not move, so that the reinforcing rod 403 supports one side of the outer end of the lifting plate 3, further enhancing the stability when the mold body is supported, and the safety protection performance is good. Then, when it is necessary to retract the lifting body 1, the threaded rod 1 401 rotates in the opposite direction to drive the internal thread seat 402 to move downward, so that the lifting plate 3 can be retracted. In other words, by setting the reinforcing rod 403, the lifting plate 3 can be driven to move horizontally, and the stability can be further improved, which is highly practical.

[0057] Preferably, after the closed door 105 is closed, the lifting plate 3 can no longer move outward. If the threaded rod 401 starts to rotate again and drives the internal threaded seat 402 to move upward, the reinforcing rod 403 and the lifting plate 3 are directly pushed to move upward, and the mold body can be driven to lift upward to the corresponding support frame plate 201. In other words, the lifting plate 3 can be horizontally displaced and further moved up and down by driving the threaded rod 401, which is highly practical and saves costs.

[0058] Preferably, in order to prevent the lifting plate 3 from generating a force to move outward, thereby reopening the closed door 105, the second magnet block is preferably set as an electromagnet, and the closed door 105 is fixedly adsorbed or released by turning on and off the power, thereby preventing the lifting plate 3 from initially pushing the closed door 105 open, thereby improving stability;

[0059] Preferably, after the closed door 105 is closed, although the lifting plate 3 cannot move outward any more, the internal threaded seat 402 will always exert a force on the lifting plate 3 to move outward when it moves upward, so that the lifting plate 3 rubs against the closed door 105 and the observation window 3 602 during the lifting process, which will cause serious wear after long-term use. Therefore, a plurality of roller members 801 (such as Figure 4 , Figure 5 As shown), when the lifting plate 3 is lifted or lowered, the roller member 801 rolls against the closed door 105 and the observation window 3 602, thereby further reducing the friction force and ensuring the smoothness of the lifting plate 3.

[0060] Both ends of the lifting plate 3 are provided with transverse grooves, the inner side of which is provided with a rack groove 304, a gear 1 303 is arranged in the transverse groove, the rack groove 304 is meshedly connected with the gear 1 303, and the threaded rod 1 401 penetrates the gear 1 303 and is threadedly connected with it.

[0061] Preferably, in order to further improve the stability of the lifting plate 3 when the bearing mold body is displaced and reduce the reaction force on the reinforcing rod 403, a gear 303 is provided. Specifically, the threaded rod 401 is threadedly connected with the gear 303. When the lifting plate 3 needs to be displaced to the outside of the lifting body 1, the staff opens the closed door 105. At this time, the threaded rod 401 rotates to drive the internal threaded seat 402 to move upward, so that the reinforcing rod 403 drives the lifting plate 3 to move outward. At the same time, the threaded rod 401 also drives the gear 303 to rotate at the same time and meshes with the rack groove 304, thereby further assisting the reinforcing rod 403 to drive the lifting plate 3 outward, avoiding the reinforcing rod 403 to push only, so that the reaction force on the reinforcing rod 403 is too large, and the stability of pushing the lifting plate 3 to move is improved;

[0062] Preferably, when the lifting plate 3 needs to be driven to move upward, the staff closes the closed door 105 so that the lifting plate 3 cannot move outward. At this time, the threaded rod 1 401 rotates, which can only drive the gear 1 303 and the internal thread seat 402 to move upward at the same time, and simultaneously bear the pressure brought by the mold body, thereby improving the service life;

[0063] Preferably, when the internal thread seat 402 moves upward and the driving reinforcing rod 403 pushes the lifting plate 3, in order to avoid that the lifting plate 3 initially moves outward faster than the internal thread seat 402 moves upward, resulting in a different speed of engagement with the gear 1 303 driving the rack groove 304, that is, there is a transmission speed difference between the two, resulting in movement interference, an adaptable vertical groove 5 is provided, a fixed guide rod 501 is fixedly connected in the adaptable vertical groove 5, an adaptable rod 502 is rotatably connected to the inner side of the internal thread seat 402, the adaptable rod 502 is penetrated by the fixed guide rod 501, and in the adaptable vertical groove 5, the adaptable rod 502 is rotated to rotate ... The lifting plate 3 slides in the groove 5, and a spring part is arranged on the outer side of the fixed guide rod 501. In the initial state, the lifting plate 3 is driven outward by the gear 1 303, and the internal thread seat 402 and the adaptation rod 502 are also displaced upward. The elastic force of the spring part assists in pushing the reinforcing rod 403 and the lifting plate 3 to move outward. The adaptation rod 502 slowly slides upward relative to the fixed guide rod 501 to adapt to the speed difference. Until the lifting plate 3 is fully extended, the adaptation rod 502 also slides to the upper end of the adaptation vertical groove 5 to stably support the reinforcing rod 403, and the mold body can be placed on the lifting plate 3.

[0064] A through slot 109 is formed through the lower end of the vertical support plate 106, and a brake block 110 is slidably fitted in the through slot 109. One end of the brake block 110 is fixedly connected to a connecting plate 111, and both ends of the connecting plate 111 are fixedly connected to guide rods 112, which penetrate the vertical support plate 106 and slide with it. An end cover is fixedly connected to the outer end of the guide rod 112, and a spring member is sleeved on the outer side of the guide rod 112. A square slot that adapts to the connecting plate 111 is formed on the inner side of the vertical support plate 106. When the brake block 110 extends out of the through slot 109, it limits the upward displacement of the horizontal plate 302.

[0065] Preferably, in the above embodiment, the threaded rod 401 and the gear 303 are threadedly connected. When the lifting plate 3 needs to be moved outward, it is necessary to ensure that the threaded rod 401 does not drive the gear 303 to move upward, but the threaded rod 401 drives the gear 303 to rotate synchronously. Therefore, a brake block 110 is provided. When the lifting plate 3 needs to be driven to move outward, the brake block 110 extends out of the through slot 109 and is stuck at one end of the upper side of the horizontal plate 302 (such as Figure 6 As shown), the horizontal plate 302 and the lifting plate 3 are restricted from moving upward. At this time, the rotation of the threaded rod 401 cannot drive the gear 303 to move upward, but it is driven to rotate synchronously, so as to drive the lifting plate 3 to move outward, and the stability is strong;

[0066] Preferably, in the initial state, under the action of the spring member, the brake block 110 is retracted into the through groove 109 and the connecting plate 111 is retracted into the square groove, so as not to affect the lifting and lowering movement of the horizontal plate 302 inside. When the horizontal plate 302 and the lifting plate 3 move to the bottom, the brake block 110 moves to the upper side of the horizontal plate 302 to restrict it.

[0067] The upper end of the closed door 105 is fixedly connected to a shaft 108, which passes through a pair of vertical support plates 106 and is rotatably connected thereto. A reel 113 is fixedly connected to the outer side of the shaft 108, and a pair of connecting ropes 114 are reeled up on the outer side of the reel 113. A vertical through groove is provided on the inner side of the vertical support plate 106, and the connecting rope 114 moves in the vertical through groove. The lower end of the connecting rope 114 is connected to a lifting block 115, and a triangular wedge block 116 is fixedly connected to the upper end of the lifting block 115. One end of the brake block 110 is provided with an oblique chamfer, and the triangular wedge block 116 is adapted to the brake block 110. A vertical groove is provided on the inner side of the vertical support plate 106, and the lifting block 115 slides in the vertical groove.

[0068] Preferably, the closed door 105 is opened by a staff member, and the closed door 105 drives the shaft rods 108 on both sides to rotate, thereby driving the winding sleeve 113 to rotate, and the winding sleeve 113 reels the connecting rope 114, so that the connecting rope 114 pulls the lower lifting block 115 to rise, and the triangular wedge block 116 rises and pushes the brake block 110 through the inclined surface, so that it slides along the inclined surface, thereby extending out of the through slot 109, and restricting the horizontal plate 302, and the threaded rod 401 can drive the lifting plate 3 to move outward, that is, by opening the closed door 105, the height of the horizontal plate 302 is further restricted to ensure the horizontal displacement of the lifting plate 3, and no additional drive components or control programs are required for control, which saves costs;

[0069] When the lifting plate 3 is reset and retracted, the staff closes the closed door 105 again, so that the winding sleeve 113 releases the connecting rope 114. Under the reset action of the spring member, the brake block 110 is reset to release the restriction on the horizontal plate 302.

[0070] The linear drive mechanism also includes a pair of threaded rods 305, which penetrate the horizontal plate 302. The upper ends of the pair of threaded rods 401 and the pair of threaded rods 305 are fixedly connected with sprockets 306. A transmission chain is arranged between the four sprockets 306. The sprockets 306 are rotatably connected to the upper plate 101.

[0071] Preferably, in the above embodiment, a pair of threaded rods 401 are provided to drive the lifting plate 3 to be lifted and lowered. However, only a pair of threaded rods 401 are provided on one side of the lifting plate 3, while the other side lacks support, resulting in uneven force when the supporting mold body is lifted and lowered, which easily causes the lifting plate 3 to break and poor lifting stability. Therefore, in order to improve the stability of the lifting plate 3 moving up and down, a vertical rod can be provided at the other side, and the vertical rod passes through the horizontal plate 302 for guidance, thereby further increasing the stability of the movement of the horizontal plate 302 and the lifting plate 3.

[0072] Preferably, since the lifting plate 3 carries a large weight, in the above embodiment, when the vertical rod is provided for guidance, only one side is driven and the other side is driven to move, which still causes uneven force on the lifting plate 3. Therefore, a pair of threaded rods 305 are provided. Specifically, the threaded rods 305 are provided away from the threaded rods 401 to lift and drive the horizontal plate 302, so that the four corners of the lifting plate 3 can all be driven to lift and drive, thereby evenly exerting force and ensuring the stability of lifting.

[0073] Preferably, a sprocket wheel 306 and a transmission chain are provided so that a pair of threaded rods 401 and a pair of threaded rods 305 rotate synchronously, thus saving costs and ensuring the synchronization of lifting and lowering.

[0074] The threaded rod 2 305 is loosely matched with the horizontal plate 302, a transmission groove is provided inside the horizontal plate 302, one side of the gear 1 303 is meshedly connected with the gear 2 307, the gear 2 307 is rotatably connected in the transmission groove, one side of the gear 2 307 is meshedly connected with the gear 3 310, the upper end of the gear 3 310 is fixedly connected with the sprocket 2 308, one side of the sprocket 2 308 is provided with the sprocket 3 309 and the two are connected by chain transmission, the threaded rod 2 305 passes through the sprocket 3 309 and is threadedly connected to it.

[0075] Preferably, since the threaded rod 1 401 can drive the lifting plate 3 to rise and fall while also driving the lifting plate 3 to rise and fall, the threaded rod 2 305 rotates synchronously at this time, which will drive the lifting plate 3 to rise, causing mutual interference. Therefore, gear 2 307 and gear 3 310 are provided. Specifically, the threaded rod 2 305 passes through the sprocket 3 309 and is connected with the thread. When the threaded rod 1 401 drives the lifting plate 3 to move outward, it drives gear 1 303 to rotate, and gear 1 303 drives gear 2 307, gear 3 310 and sprocket 2 308 to rotate. The sprocket 3 309 is driven to rotate through the chain transmission, so that the rotation of the sprocket 3 309 is synchronized with the rotation of the threaded rod 2 305, and no interference is caused. When it is necessary to drive the lifting plate 3 to rise and fall, the gear 1 303 cannot rotate, that is, the sprocket 3 309 cannot rotate. The threaded rod 1 401 and the threaded rod 2 305 can drive the gear 1 303 and the sprocket 3 309 to rise and fall, and can drive the lifting plate 3 and the horizontal plate 302 to rise and fall.

[0076] A mold frame 2 is also provided on one side of the lifting body 1. The mold frame 2 includes a support frame plate 201. The support frame plate 201 is used to store the mold body. The support frame plate 201 is provided with multiple layers and is evenly arranged vertically.

[0077] A suction cup assembly is also provided on one side of the mold frame 2 , and the suction cup assembly is used to suck and push the mold body back and forth between the lifting plate 3 and the support frame plate 201 .

[0078] Preferably, a matching mold frame 2 can be provided for use with the lifting body 1 to achieve the taking and storage of the mold body. Specifically, when the mold body is displaced to the support frame plate 201 of any height, the lifting plate 3 is aligned with the support frame plate 201, and the suction cup assembly is moved and adsorbed on the side of the mold body, so that it can be displaced and pulled from the lifting plate 3 to the support frame plate 201 to complete the automatic storage function. Similarly, when the mold body needs to be taken out, the lifting plate 3 is first moved to the support frame plate 201, and the mold body is pushed onto the lifting plate 3 through the suction cup assembly. The lifting plate 3 then moves with it and extends out of the outside of the lifting body 1, so that it is convenient for the staff to take it, and there is no need to manually carry or use a driving mechanism to store or take mold bodies of different heights, thereby improving convenience and safety. In addition, a fully enclosed frame is provided to avoid pollution caused by the external environment after long-term storage, and also to eliminate the risk of the mold body falling under external influences, thereby further improving protection safety.

[0079] Preferably, in order to further improve the convenience of observing the storage status or specifications of several mold bodies stored in the mold frame 2, a light-guiding lighting system is provided. By inlaying light guide tubes and light sources at the bottom of each layer of the support frame plate 201, layered lighting is achieved, which is convenient for checking the details of each layer of the mold body, and further improves the operating efficiency and safety of the staff and improves the working environment.

[0080] A pair of observation windows 1 6 are arranged on both sides of the mold frame 2, a pair of observation windows 2 601 are arranged on both sides of the lifting body 1, the mold frame 2 also includes a back plate 103 and a bottom plate 102, and an observation window 3 602 is arranged on the side of the lifting body 1 away from the back plate 103.

[0081] An observation window assembly is further provided to observe the internal mold body and storage status, thereby improving the aesthetics.

[0082] The four sides of the support frame plate 201 are fixedly connected with fixed rods 202, and the suction cup assembly includes an electric suction cup 203. One end of the electric suction cup 203 is fixedly connected with a convex plate 204. The convex plate 204 is driven to move by the cylinder assembly. A guide rod 205 is fixedly connected between the fixed rods 202 on both sides. The guide rod 205 passes through the convex plate 204 and slides with it.

[0083] Preferably, a cylinder assembly (not shown in the figure) can be provided on the rear side of the back plate 103 to drive the convex plate 204, thereby pushing the electric suction cup 203 to move, thereby adsorbing and driving the mold body to move from the lifting plate 3 to the support frame plate 201, and the guide rod 205 provides guidance to improve stability.

[0084] Rollable rollers 8 are disposed on the surfaces of the support frame plate 201 and the lifting plate 3 .

[0085] Preferably, in order to reduce the friction force of the mold body displacement, a roller 8 (such as Figure 3 As shown), by rolling the roller 8, the friction of the mold body moving back and forth between the support frame plate 201 and the lifting plate 3 is reduced, which is highly practical.
