Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a mold guiding structure. Background Technology

[0002] The mold guide structure is an important component in the mold used to ensure precise positioning and guidance between the moving mold and the fixed mold, the upper mold and the lower mold, or other related components. Its core function is to ensure that the movement of each component is smooth and the position is accurate during the mold closing and opening process, thereby ensuring the precision and quality of the molded product, while avoiding damage to the mold due to misalignment.

[0003] A search revealed Chinese patent publication number CN216230471U, which discloses a mold guiding structure for guiding mold closing. The fixed mold has a guide strip and a limiting groove. The guide strip is located on the fixed mold and has a limiting block. The moving mold has a guide groove, and first wear-resistant blocks are connected to both sides of the guide groove. The guide strip and the first wear-resistant blocks are slidably connected. While guiding the mold, this structure transfers the friction-bearing component from the moving mold to the first wear-resistant block, extending the service life of the moving mold. Furthermore, the limiting blocks confine the guide strip within the limiting groove, further ensuring the positioning accuracy of the entire guiding structure and guaranteeing the quality of the molded product. However, during production, due to prolonged use or excessively high sprinting frequency, the guide post may be pulled out along with the upper mold guide sleeve, causing production stoppages and mold damage. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a mold guiding structure, which aims to improve the problem in the prior art where the guide post is carried out along with the upper mold guide sleeve during long-term use or excessively fast sprinting frequency, causing production stoppage and mold damage.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a mold guiding structure, including an upper mold, a lower mold disposed on the top of the upper mold, a guiding mechanism disposed on the top of the upper mold for guiding, a fixing mechanism disposed on the outer wall of the upper mold for fixing the upper mold and the lower mold when changing the mold; the guiding mechanism includes positioning blocks, a plurality of positioning blocks are equidistantly disposed at the four corners of the upper mold, the upper portion of the plurality of positioning blocks is fixedly connected to the four corners of the bottom wall of the lower mold, the lower portion of the plurality of positioning blocks is fixedly connected to the four corners of the top wall of the upper mold, the inner wall of the lower positioning block is provided with a guide post, the lower part of the outer wall of the guide post is fixedly connected with an anti-detachment block, the top of the guide post is provided with a guide sleeve, the guide sleeve is slidably connected to the guide post, the outer walls of the guide sleeve and the guide post are both equidistantly provided with fixing claws, and the outer walls of the fixing claws are threaded with bolts.

[0006] Through the above technical solution: the upper mold and the lower mold are initially aligned by positioning blocks located at the four corners. When the mold is closed, the guide post of the lower positioning block and the upper guide sleeve cooperate with each other to achieve a precise guiding function and ensure the positioning accuracy during the downward movement of the mold. The guide post and the guide sleeve are fixed to the positioning block by bolts on the fixing claw. The anti-detachment block at the bottom of the guide post effectively prevents the guide post from being accidentally pulled out by the guide sleeve, thereby ensuring the safety of the mold opening and closing process.

[0007] As a further description of the above technical solution:

[0008] The fixing mechanism includes connecting plates, and multiple connecting plates are disposed on the left and right sides of the outer wall of the upper mold. Slide grooves are provided on the left and right sides of the outer walls of both the upper and lower molds. An internal hexagonal prism passes through the outer wall of the connecting plate. A locking block is fixedly connected to an adjacent side of the outer wall of the multiple internal hexagonal prisms. A locking groove is provided on the inner wall of the slide groove. The locking block engages with the locking groove. A fixing component is provided on the outer wall of the upper mold.

[0009] The above technical solution involves placing the connecting plate on the left and right sides of the upper mold, then sliding the internal hexagonal column through the connecting plate into the grooves on the outer walls of the upper and lower molds. Rotating the internal hexagonal column causes the locking block on it to engage with the locking groove of the groove, thus achieving the initial fixation of the upper and lower molds.

[0010] As a further description of the above technical solution:

[0011] The fixing component includes a nut, which is disposed on the left and right sides of the outer wall of the upper mold. The outer walls of the plurality of internal hexagonal prisms are provided with threaded grooves on the opposite side, and the threaded grooves are threadedly connected to the nut.

[0012] The above technical solution involves the nut rotating in the threaded groove of the internal hexagonal column, clamping the connecting plate, thereby firmly fixing the upper and lower molds when changing molds.

[0013] As a further description of the above technical solution:

[0014] The lower fixing claw is located at the top of the anti-detachment block, and the upper fixing claw is located at the bottom of the guide sleeve.

[0015] Through the above technical solution: the fixing claw is used to fix the anti-detachment block to prevent the guide post from coming out of the positioning block, and the fixing claw is used to fix the guide sleeve to prevent the guide sleeve from loosening or falling off due to vibration or force when the lower mold moves.

[0016] As a further description of the above technical solution:

[0017] The lower fixing claw is threadedly connected to the lower positioning block by bolts, and the upper fixing claw is threadedly connected to the upper positioning block by bolts.

[0018] The above technical solution involves tightening bolts to securely install the guide post and guide sleeve at the corner of the upper and lower molds.

[0019] As a further description of the above technical solution:

[0020] The groove is slidably connected to the internal hexagonal column, which is located at the upper and lower ends of the outer wall of the connecting plate.

[0021] The above technical solution provides sliding space for the internal hexagonal column, allowing it to move along the slide and ensuring that the locking block on the internal hexagonal column slides into the locking slot. Internal hexagonal columns are provided at both the upper and lower ends of the connecting plate, so that the force points are distributed on the upper and lower sides of the connecting plate, avoiding the connecting plate from tilting or deforming due to force on one side, and ensuring the fitting accuracy of the upper and lower molds.

[0022] As a further description of the above technical solution:

[0023] The upper and lower molds are provided with pins on the front and rear sides and left and right ends of their outer walls. The upper pin engages with the lower mold, and the lower pin engages with the upper mold.

[0024] The above technical solution uses pins to fix the components inside the upper and lower molds.

[0025] As a further description of the above technical solution:

[0026] The outer walls of the upper and lower molds are provided with mounting holes, which are symmetrically distributed on the outer walls of the upper and lower molds.

[0027] The above technical solution, which fixes the upper and lower molds to the worktable of the equipment through mounting holes, ensures the stability of the mold under high-pressure working conditions.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, the upper mold and the lower mold are initially aligned using positioning blocks at four corners. When closed, the guide post of the positioning block cooperates with the guide sleeve to ensure accurate guidance. The guide post and the guide sleeve are fixed to the fixing claw by bolts, while the anti-detachment block prevents the guide post from being pulled out by the guide sleeve, ensuring the safety of mold opening and closing.

[0030] 2. In this utility model, the connecting plate is first placed on the left and right sides of the upper mold. Then, the internal hexagonal column passes through the connecting plate and slides into the groove of the upper and lower molds. The internal hexagonal column is rotated to make the locking block engage with the locking groove of the groove to initially fix the upper and lower molds. Then, the nut is rotated in the threaded groove of the internal hexagonal column to clamp the connecting plate and ensure the stability of the upper and lower molds when changing molds.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Reference Figure 2 , Figure 3 and Figure 4 The present invention provides an embodiment of a mold guiding structure, including an upper mold 1, a lower mold 2 disposed on the top of the upper mold 1, a guiding mechanism 3 disposed on the top of the upper mold 1 for guiding, and a fixing mechanism 4 disposed on the outer wall of the upper mold 1 for fixing the upper mold 1 and the lower mold 2 when changing the mold.

[0040] The guiding mechanism 3 includes positioning blocks 301. Multiple positioning blocks 301 are equidistantly arranged at the four corners of the upper mold 1. The upper positioning blocks 301 are fixedly connected to the four corners of the bottom wall of the lower mold 2, and the lower positioning blocks 301 are fixedly connected to the four corners of the top wall of the upper mold 1. A guide post 302 is provided on the inner wall of the lower positioning block 301. A release block 304 is fixedly connected to the lower middle part of the outer wall of the guide post 302. The release block 304 at the bottom of the guide post 302 effectively prevents the guide post 302 from being pulled out by the guide sleeve 303. The guide sleeve 303 is slidably connected to the guide post 302. A guide sleeve 303 is provided on the top of the guide post 302. The guide post 302 of the positioning block 301 is connected to the upper mold 1... The guide sleeves 303 cooperate with each other when the mold is closed to achieve precise guidance during the downward movement. The outer walls of the guide sleeves 303 and the guide pillars 302 are provided with fixing claws 305 at equal intervals. The outer walls of the fixing claws 305 are threaded with bolts 306. The lower fixing claw 305 is located on the top of the anti-detachment block 304, and the upper fixing claw 305 is located at the bottom of the guide sleeve 303. The guide pillars 302 and the guide sleeves 303 are fixed to the positioning block 301 by the bolts 306 on the fixing claws 305. The lower fixing claw 305 is threaded to the lower positioning block 301 by the bolts 306, and the upper fixing claw 305 is threaded to the upper positioning block 301 by the bolts 306.

[0041] Specifically, the guiding mechanism 3 is used for guiding, and the fixing mechanism 4 is used to fix the upper mold 1 and the lower mold 2 when changing the mold. The upper mold 1 and the lower mold 2 are initially aligned by the positioning blocks 301 located at the four corners. During the mold closing process, the guide post 302 of the lower positioning block 301 and the guide sleeve 303 of the upper positioning block cooperate with each other to achieve precise guiding control. The guide post 302 and the guide sleeve 303 are fixed to the positioning block 301 by the bolts 306 on the fixing claw 305. In addition, the anti-detachment block 304 at the bottom of the guide post 302 can effectively prevent the guide post 302 from being pulled out under the action of the guide sleeve 303, thereby ensuring the safety of the mold during the opening and closing process.

[0042] Reference Figure 3 and Figure 5 The fixing mechanism 4 includes a connecting plate 401. Multiple connecting plates 401 are disposed on the left and right sides of the outer wall of the upper mold 1. Slide grooves 402 are provided on the left and right sides of the outer walls of the upper mold 1 and the lower mold 2. An internal hexagonal prism 403 passes through the outer wall of the connecting plate 401. A locking block 404 is fixedly connected to the adjacent side of the outer wall of multiple internal hexagonal prisms 403. A slot 405 is provided on the inner wall of the slide groove 402. The locking block 404 engages with the slot 405. Rotating the internal hexagonal prism 403 causes the locking block 404 to engage with the slot 405 of the slide groove 402. A fixing component 406 is provided on the outer wall of the upper mold 1. The slide groove 402 is slidably connected to the internal hexagonal prism 403. The internal hexagonal prism 403 is slidably inserted into the slide groove 402 on the outer wall of the upper mold 1 and the lower mold 2 through the connecting plate 401. The internal hexagonal prism 403 is disposed at the upper and lower ends of the outer wall of the connecting plate 401.

[0043] The fixing component 406 includes a nut 4061, which is disposed on the left and right sides of the outer wall of the upper mold 1. The outer walls of multiple hexagonal sockets 403 are provided with threaded grooves 4062 on opposite sides. The threaded grooves 4062 are threadedly connected to the nut 4061. The nut 4061 is rotated in the threaded grooves 4062 of the hexagonal sockets 403 to clamp the connecting plate 401, thereby firmly fixing the upper mold 1 and the lower mold 2 when changing the mold.

[0044] Specifically, first, the connecting plate 401 is placed on the left and right sides of the upper mold 1. Then, the internal hexagonal column 403 is passed through the connecting plate 401 and slid into the groove 402 on the outer wall of the upper mold 1 and the lower mold 2. By rotating the internal hexagonal column 403, the locking block 404 on it is engaged with the locking groove 405 of the groove 402, thereby achieving the initial fixation of the upper mold 1 and the lower mold 2. Subsequently, the nut 4061 is tightened in the threaded groove 4062 of the internal hexagonal column 403 to clamp the connecting plate 401, ensuring that the upper mold 1 and the lower mold 2 can be firmly fixed when changing molds. When disassembling, the nut 4061 needs to be loosened in the opposite direction and the internal hexagonal column 403 is slid to make the locking block 404 disengage from the locking groove 405, so as to separate the upper mold 1 and the lower mold 2.

[0045] Reference Figure 1 and Figure 2 Pins 5 are provided on the front and rear sides and left and right ends of the outer wall of the upper mold 1 and the lower mold 2. The upper pin 5 engages with the lower mold 2 and the lower pin 5 engages with the upper mold 1. The pins 5 are used to fix the internal components of the upper mold 1 and the lower mold 2. The outer wall of the upper mold 1 and the lower mold 2 is provided with mounting holes 6. The mounting holes 6 are symmetrically distributed on the outer wall of the upper mold 1 and the lower mold 2. The upper mold 1 and the lower mold 2 are fixed to the worktable of the equipment through the mounting holes 6, which can ensure the stability of the mold under high pressure working environment.

[0046] Specifically, the pin 5 is used to fix the internal components of the upper mold 1 and the lower mold 2. The upper mold 1 and the lower mold 2 are fixed to the worktable of the equipment through the mounting hole 6, which can ensure the stability of the mold under high pressure working environment.

[0047] Working principle: The upper mold 1 and the lower mold 2 are initially aligned by the positioning blocks 301 at the four corners. The guide post 302 of the lower positioning block 301 and the guide sleeve 303 of the upper positioning block cooperate with each other when the mold is closed to achieve precise guidance during the downward movement. The guide post 302 and the guide sleeve 303 are fixed to the positioning block 301 by the bolts 306 on the fixing claw 305. The anti-detachment block 304 at the bottom of the guide post 302 effectively prevents the guide post 302 from being pulled out by the guide sleeve 303, ensuring the safety of the mold opening and closing process.

[0048] First, place the connecting plate 401 on the left and right sides of the upper mold 1 and the lower mold 2. Then, slide the hexagonal socket 403 through the connecting plate 401 into the groove 402 on the outer wall of the upper mold 1 and the lower mold 2. Rotate the hexagonal socket 403 so that the locking block 404 on it engages with the locking groove 405 of the groove 402, thus initially fixing the upper mold 1 and the lower mold 2. Rotate the nut 4061 in the threaded groove 4062 of the hexagonal socket 403 to clamp the connecting plate 401, thereby firmly fixing the upper mold 1 and the lower mold 2 when changing molds. When disassembling, loosen the nut 4061 in the opposite direction and slide the hexagonal socket 403 to disengage the locking block 404 from the locking groove 405, thus separating the upper mold 1 and the lower mold 2.
