Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a multi-directional core-pulling mold. Background Technology

[0002] Dust collection cups, as a common type of plastic product, typically have a relatively complex structure. For example... Figure 1 As shown, the dust collection cup product has an inner wall groove 501 and an outer wall groove 502, which are connected. The top also has a snap-fit ​​hole 503 for connection with an external snap-fit ​​device. During injection molding, the structures of the inner wall groove 501, outer wall groove 502, and snap-fit ​​hole 503 all interfere with the mold opening direction. The demolding directions of these three structures are different from each other, making direct demolding impossible through simple top and bottom mold opening. Utility Model Content

[0012] According to some embodiments of the present invention, the upper template has a limiting groove arranged along a first direction and a through hole arranged at the bottom of the limiting groove. One end of the limiting rod passes downward along the limiting groove through the through hole and is fixed at the bottom of the receiving groove. The other end of the limiting rod is provided with a second limiting block. The diameter of the second limiting block is larger than the diameter of the through hole. When the mold is closed, the bottom of the second limiting block is spaced apart from the bottom of the limiting groove by a preset distance.

[0013] According to some embodiments of the present invention, the inclined slider structure is provided with a positioning block on the other side of the inner wall groove forming part, and the upper mold core is provided with an upper positioning groove and a lower positioning groove on the side wall near the positioning block.

[0018] This utility model has at least the following beneficial effects:

[0019] By nesting the snap-hole core-pulling mechanism within the outer wall groove core-pulling mechanism, and utilizing the opening motion of the upper mold core to simultaneously drive the inner wall core-pulling mechanism and the snap-position core-pulling mechanism, a multi-action effect is achieved, simplifying the overall mold structure, reducing the number of independent drive sources, and making the mold layout more compact. The simplified overall mold structure reduces the number of independent drive sources (such as hydraulic cylinders), making the mold smaller and more compact. The inner wall core-pulling mechanism and the snap-position core-pulling mechanism simultaneously pull cores sideways with the opening of the upper mold plate and upper mold core, without interference or influence, improving core-pulling efficiency. The outer wall groove core-pulling is performed last. The structure is compact, the operation is reliable, and it can efficiently solve the problem of core pulling in multiple different directions, avoiding any impact on the structure of either mechanism. The linkage timing is inherent and precise, improving the reliability and stability of the operation. Attached Figure Description

[0030] This invention provides the following description with reference to the accompanying drawings to aid in a comprehensive understanding of the various embodiments of the invention as defined by the claims and their equivalents. The description includes various specific details to aid understanding, but these details should be considered exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the invention.

[0031] In the description of this utility model, the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0032] It should be understood that when one element (e.g., the first element) is “connected” to another element (e.g., the second element), the element may be directly connected to the other element, or there may be an intervening element (e.g., the third element) between the element and the other element.

[0033] An embodiment of this utility model provides a multi-directional core-pulling mold, such as... Figure 1-10 As shown, it includes:

[0034] Upper template 11, upper mold core 12 located below the upper template 11, and lower mold assembly 13 located below the upper mold core 12;

[0035] The inner wall core pulling mechanism 2 includes a slanted slider structure 201 disposed on the lower mold assembly 13, an inner wall groove forming part 202 disposed on the outside of the slanted slider structure 201, a slanted slider limiting block 203 fixed on the lower mold assembly 13 and slidably connected to the slanted slider structure 201, and an elastic structure 204. The slanted slider structure 201 is slidably connected to the upper mold core 12 in a first direction, and the slanted slider structure 201 can move in a second direction under the restriction of the slanted slider limiting block 203.

[0036] The outer wall core pulling mechanism 3 includes a first side core pulling slider 301 disposed on the lower mold assembly 13, an outer wall groove forming part 302 disposed inside the first side core pulling slider 301, and a driving structure 303 for driving the first side core pulling slider 301 to move in a second direction.

[0037] The snap-fit ​​core-pulling mechanism 4 includes a second-side core-pulling slider 401 disposed on the first-side core-pulling slider 301, a snap-fit ​​hole forming part 402 disposed on the second-side core-pulling slider 401, and a drive block 403 fixed to the bottom of the upper mold core 12. The drive block 403 is slidably connected to the second-side core-pulling slider 401 and is used to guide the second-side core-pulling slider 401 to move in a third direction.

[0038] When the mold is opened, the upper mold plate 11 and the upper mold core 12 move upward synchronously. The upper mold core 12 moves upward and generates relative displacement with the inclined slider structure 201 in the first direction. The inclined slider limiting block 203 restricts the displacement of the inclined slider structure 201 in the mold opening direction, so that the inclined slider structure 201 can only move laterally along the second direction away from the inner wall groove forming part 202 to pull the core. When the inner wall groove forming part 202 of the inclined slider structure 201 is completely pulled out from the inner wall groove 501 of the dust collection cup product, the inclined slider limiting block 203 can disengage from the inclined slider structure 201 and move upward synchronously with the upper mold plate 11 and the upper mold core 12 under the pull of the elastic structure 204. The elastic structure 204 can be pulled by a spring or by a pulling rod. Simultaneously, the upper mold core 12 moves upward, synchronously driving the drive block 403 to move upward, so that the second side core-pulling slider 401, guided by the drive block 403, pulls the core along the third direction away from the snap-hole forming part 402, realizing lateral core pulling of the snap-hole in the third direction. Finally, the first side core-pulling slider 301, driven by the drive structure 303 such as the motor, hydraulic cylinder, and pneumatic cylinder, pulls the core along the second direction away from the outer wall groove forming part 302. The entire system utilizes the opening movement of the upper mold plate 11 and the upper mold core 12 to simultaneously drive the inner wall core-pulling mechanism 2 and the snap-locking core-pulling mechanism 4, achieving the effect of "one movement driving multiple movements", simplifying the overall structure of the mold, reducing the number of independent drive sources, and making the mold layout more compact.

[0039] In some embodiments, such as Figure 3-4As shown, the inclined slider limiting block 203 includes a first limiting block 205 arranged horizontally and a connecting block 206 arranged vertically. The bottom of the inclined slider structure 201 is provided with a horizontal groove 208 that matches the first limiting block 205 and a vertical groove 207 that matches the connecting block 206. The bottom surface of the horizontal groove 208 can abut against the bottom surface of the first limiting block 205. When the mold is closed, the inner sidewall of the vertical groove 207 near the inner wall groove forming part 202 is spaced apart from the sidewall of the connecting block 206 by a preset distance.

[0040] When the mold is closed, the first limiting block 205 is located in the horizontal groove 208, and the connecting block 206 is located on the side of the vertical groove 207 away from the inner wall groove forming part 202. When the mold is opened, the upper mold core 12 moves upward and generates relative displacement with the inclined slider structure 201. The bottom of the first limiting block 205 abuts against the bottom surface of the horizontal groove 208, so that the inclined slider structure 201 is limited as a whole and cannot move upward with the upper mold core 12. It can only be pulled laterally in the second direction with the relative displacement with the upper mold core 12, thereby improving the core pulling quality of the inner wall groove and preventing collision with the vertical direction. The connecting block 206 fixes the first limiting block 205 to the lower mold assembly 13, while the inclined slider structure 201 continues to pull the core. The connecting block 206 gradually moves closer to the other side of the vertical groove 207, and the first limiting block 205 gradually separates from the horizontal groove 208. When the first limiting block 205 completely separates from the horizontal groove 208, the inclined slider structure 201, under the pull of the elastic structure 204, separates from the inclined slider limiting block 203 and moves upward as the upper mold core 12 moves upward. The inner sidewall of the vertical groove 207 near the inner wall groove forming part 202 is spaced at a preset distance from the sidewall of the connecting block 206 to ensure the core-pulling distance of the inclined slider structure 201 while preventing excessive core-pulling. This preset distance is determined by those skilled in the art based on the actual core-pulling distance.

[0041] Furthermore, such as Figure 3-4 As shown, the top of the inclined slider structure 201 has a receiving groove 209 arranged along the first direction, and the elastic structure 204 includes a limiting rod 210 connected to the upper template 11 and a spring 211 sleeved on the outside of the limiting rod 210. When the mold is closed, the top of the inclined slider structure 201 abuts against the bottom of the upper template 11, and one end of the spring 211 abuts against the bottom of the upper template 11, and the other end abuts against the bottom of the receiving groove 209.

[0042] During mold opening, the upper mold plate 11 and the upper mold core 12 move upward simultaneously. The inclined slider structure 201 is limited by the first limiting block 205. The spring 211 can be in two states: either the spring 211 is fixed to the upper mold plate 11 or the upper mold core 12, or the spring 211 is not fixed. In the first case, during mold opening, the inclined slider structure 201 is limited by the inclined slider limiting block 203, and the spring 211 is gradually stretched. When the inclined slider structure 201 disengages from the inclined slider limiting block 203, the stretched spring 211 contracts and pulls the inclined slider structure 201 away. In the second scenario: During mold opening, the spring 211 compressed during mold closing is gradually released, simultaneously providing a downward force to the inclined slider structure 201, preventing it from jamming with the first limiting block 205 during core pulling in the second direction. When the first limiting block 205 disengages from the transverse groove 208, the limiting rod 210 can pull the inclined slider structure 201 upward along with the upper mold core 12 and the upper template 11. During mold closing, in both scenarios, the spring 211 is compressed within the receiving groove 209, and the top of the inclined slider structure 201 is pressed against the bottom of the upper template 11, ensuring the stability of the inclined slider structure 201's position and preventing displacement, thus ensuring the stable formation of the inner wall groove.

[0043] Furthermore, such as Figure 4 As shown, the upper template 11 has a limiting groove 212 arranged along the first direction and a through hole 213 arranged at the bottom of the limiting groove 212. One end of the limiting rod 210 passes down through the through hole 213 along the limiting groove 212 and is fixed at the bottom of the receiving groove 209. The other end of the limiting rod 210 is provided with a second limiting block 214. The diameter of the second limiting block 214 is larger than the diameter of the through hole 213. When the mold is closed, the bottom of the second limiting block 214 is spaced apart from the bottom of the limiting groove 212 by a preset distance.

[0044] The limiting rod 210 is relatively long. When the mold opens, the upper mold plate 11 and the upper mold core 12 move upward, and the limiting rod 210 connected to the inclined slider structure 201 does not move. The second limiting block 214 gradually approaches the bottom of the limiting groove 212. After the inclined slider structure 201 separates from the inclined slider limiting block 203, when the bottom of the second limiting block 214 abuts against the bottom of the limiting groove 212, the inclined slider structure 201 can be pulled upward by the upper mold plate 11 because the diameter of the second limiting block 214 is larger than the diameter of the through hole 213. The preset distance between the bottom of the second limiting block 214 and the bottom of the limiting groove 212 is determined by those skilled in the art based on the actual space of the mold and the distance required for core pulling of the inclined slider structure 201.

[0045] In some embodiments, such as Figure 7-8As shown, the inclined slider structure 201 has a positioning block 215 on the other side of the inner wall groove forming part 202. The upper mold core 12 has an upper positioning groove 216 and a lower positioning groove 217 on the side wall near the positioning block 215. The upper positioning groove 216 and the lower positioning groove 217 are both matched with the shape of the positioning block 215, and there is a preset distance between the upper positioning groove 216 and the lower positioning groove 217.

[0046] When the positioning block 215 is engaged in the position of the upper positioning groove 216, the inclined slider structure 201 completes the mold closing, further improving the positional accuracy of the mold closing and ensuring that the inner wall groove and the outer wall groove can be connected and formed. The setting of the lower positioning groove 217 further prevents the inclined slider structure 201 from separating from the upper mold core 12, ensuring that the two molds are always relatively slidingly connected during the opening and closing process and do not derail.

[0047] Furthermore, such as Figure 7-8 As shown, the inclined slider structure 201 has a dovetail groove protrusion 218 on the other side of the inner wall groove forming part 202. The dovetail groove protrusion 218 is arranged along the first direction, and the upper mold core 12 is provided with a dovetail groove slide 219 that cooperates with the dovetail groove protrusion 218 to slide.

[0048] The dovetail-shaped protrusions and grooves cooperate to slide smoothly and accurately, while also having a certain self-locking function, realizing high-precision mold opening and closing movements. This effectively improves the stability and accuracy of the inclined slider structure 201 during the sliding process, preventing the inclined slider from shifting or shaking during movement, thereby ensuring the forming accuracy of the mold and the quality of the product.

[0049] In some embodiments, such as Figure 5 , 6 As shown in Figures 9 and 10, two snap-fit ​​core-pulling mechanisms 4 are symmetrically arranged, and the core-pulling directions of the two snap-fit ​​core-pulling mechanisms 4 are opposite. The drive block 403 includes an inclined block 405 that gradually tilts from the inside to the outside along a third direction. The second-side core-pulling slider 401 is provided with an inclined through groove 406 that matches the inclined block 405.

[0050] By setting two symmetrical snap-fit ​​core-pulling mechanisms 4 with opposite core-pulling directions, core pulling of the opposing snap-fit ​​holes 503 can be achieved. The core-pulling structure is the same, reducing additional design costs. At the same time, the cooperative design of the tilting block 405 and the oblique through groove 406 allows the second-side core-pulling slider 401 to move smoothly along the predetermined direction under the action of the drive block 403. When the mold opens, the drive block 403 moves upward with the upper mold core 12, and the tilting surface of the tilting block 405 abuts against the tilting surface of the oblique through groove 406, gradually guiding the second-side core-pulling slider 401 to move along the third direction to pull the core, ensuring the accuracy and reliability of the core-pulling action. The tilting block 405 is simple to manufacture and suitable for small displacement core-pulling movement.

[0051] Furthermore, such as Figure 9 ,10 As shown, the second side core-pulling slider 401 includes a sliding block 407 and a third limiting block 408 disposed on the sliding block 407. The snap-hole forming part 402 is disposed on the third limiting block 408, and the oblique through groove 406 is disposed on the sliding block 407. The top of the first side core-pulling slider 301 is provided with a first sliding groove 409 that cooperates with the sliding block 407 and a second sliding groove 410 that cooperates with the third limiting block 408. When the mold is closed, the side wall of the second sliding groove 410 away from the snap-hole forming part 402 is spaced apart from the side wall of the third limiting block 408 by a preset distance.

[0052] The first sliding groove 409 and the second sliding groove 410 allow the sliding block 407 and the third limiting block 408 to be embedded in the first side core-pulling slider 301, compressing the mold space and reducing production costs. Since the snap-hole forming part 402 is relatively close to the outer edge of the first side core-pulling slider 301, by additionally setting the third limiting block 408 on the sliding block 407 and setting the snap-hole forming part 402 on the third limiting block 408, the structural thickness of the second side core-pulling slider 401 near the edge is reduced, the processing difficulty of the first side core-pulling slider 301 is reduced, and the situation of thin edge wall collision damage is reduced. The sliding block 407, the third limiting block 408, and the snap-hole forming part 402 are formed in a Z-shape. Through the cooperation of the sliding block 407 and the driving block 403, the sliding block 407 and the third limiting block 408 slide laterally in the first sliding groove 409 and the second sliding groove 410, respectively. At the same time, the preset distance between the third limiting block 408 and the outer wall of the second sliding groove 410 can effectively prevent excessive interference or collision during the core pulling process, further improving the stability and service life of the mold. It also includes a guide structure 404 that surrounds the bottom of the first sliding groove 409 to form a guide groove, and a guide block 412 that slides in cooperation with the guide groove is provided on the bottom side of the sliding block 407.

[0053] In some embodiments, such as Figure 2 As shown, the outer wall groove forming part 302 of the first side core-pulling slider 301 is provided with a T-shaped groove on the other side. The driving structure 303 includes a driving member 306 and a T-shaped pull block 307 disposed on the driving member 306 and cooperating with the T-shaped groove.

[0054] A T-shaped groove is provided on the other side of the outer wall groove forming part 302 of the first side core-pulling slider 301. The driving component 306 in the driving structure 303 can stably pull the first side core-pulling slider 301 through the cooperation of the T-shaped pull block 307 and the T-shaped groove, so as to avoid the vibration during core pulling from affecting the core pulling. The vibration effect is offset by the mutual sliding of the T-shaped pull block 307 and the T-shaped groove, so as to ensure the accuracy and reliability of the core pulling action.

[0055] The terms and words used in the foregoing description and claims are not limited to their literal meaning, but are merely used by the applicant to enable a clear and consistent understanding of the present invention. Therefore, those skilled in the art should understand that the foregoing description of various embodiments of the present invention is for illustrative purposes only, and not intended to limit the present invention as defined by the appended claims and their equivalents.
