[0028] The present utility model provides the following description with reference to the drawings to assist in a comprehensive understanding of various embodiments of the present utility model as defined by the claims and their equivalents. The description includes various specific details to facilitate understanding, but these details should be regarded as merely exemplary. 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 present utility model.
[0029] In the description of the present utility model, with regard to the orientation description, for example, the orientations or positional relationships indicated by up, down, front, back, left, right, etc. are based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present utility model.
[0030] It should be understood that when an element (for example, the first element) is "connected" to another element (for example, the second element), the element can be directly connected to the other element, or there can be an intermediate element (for example, the third element) between the element and the other element.
[0031] An embodiment of the present utility model provides a mold for an automotive front waist bracket product, as Figure 1-11As shown in the figure, it includes a front mold core 101 and a rear mold core 102. A molding cavity 103 is formed between the front mold core 101 and the rear mold core 102. A core-pulling structure 2 is provided between the front mold core 101 and the rear mold core 102. The core-pulling structure 2 includes a first core-pulling component 201 and a second core-pulling component 202 which are arranged mirror-symmetrically, and a third core-pulling component 203 adjacent to the first core-pulling component 201 and the second core-pulling component 202, as Figure 1The shown front waist bracket product of the vehicle is mirror - set on the left and right sides of the vehicle. The mirror - set first core - pulling assembly 201 and second core - pulling assembly 202 can integrally mold the faces 301 of the left and right parts of the front waist bracket product of the vehicle in one injection molding, while the third core - pulling assembly 203 is used to mold the sides 302 of the left and right parts of the front waist bracket product of the vehicle, which is convenient for paired production, packaging and sales. The first core - pulling assembly 201, the second core - pulling assembly 202 and the third core - pulling assembly 203 all include a spring assembly 210 arranged on the front mold core 101, a core - pulling seat 220 connected to the spring assembly 210, a guiding assembly 230 arranged on the front mold core 101 and connected to the core - pulling seat 220, a hook assembly 240 arranged on the rear mold core 102 and connected to the core - pulling seat 220, and a molding part 250 arranged on the core - pulling seat 220. The first core - pulling assembly 201 and the second core - pulling assembly 202 further include a limiting structure 260 arranged on the front mold core 101 and connected to the core - pulling seat 220. The hook assembly 240 and the spring assembly 210 are used to drive the core - pulling seat 220 and the molding part 250 to demold under the guidance of the guiding assembly 230. The molding parts 250 of the core - pulling assemblies can integrally mold the product face 301 and the side 302 respectively, making the whole outer surface smooth without generating clamping lines. The third core - pulling assembly 203 can be an integral core - pulling seat 220 to directly mold the narrow sides of two products, or a split - type core - pulling seat 220 to respectively mold the sides 302 of the mirror - set products. The molding part 250 can be integrally arranged with the core - pulling seat 220 or fixed to the core - pulling seat 220 in the form of an insert. The spring assembly 210 is fixed on the front mold core 101 and slides inside the core - pulling seat 220. When the core - pulling seat 220 is relatively large, multiple spring assemblies 210 are required to provide the driving force. For example, when the length of the molded product face 301 is long, so three groups of spring assemblies 210 are arranged in the first core - pulling assembly 201 and the second core - pulling assembly 202 to provide sufficient driving force. The hook assembly 240 connects the core - pulling seat 220 to the rear mold core 102 and provides power for the core - pulling of the core - pulling seat 220 when the mold is opened. The guiding assembly 230 slidably connected to the core - pulling seat 220 is used to guide the core - pulling direction of the core - pulling seat 220. The limiting structure 260 can limit the stroke distance of the core - pulling seat 220 during the core - pulling process, prevent the excessive stroke of the core - pulling seat 220, protect the core - pulling structure 2, and can also assist in mold opening together with the spring assembly 210 to improve the stability of the core - pulling structure 2. When the mold is closed, the spring assembly 210 is in a compressed state. When the mold starts to open, the compressed state of the spring begins to be released. The hook assembly 240 is pulled by the front mold, so that the connected components such as the core - pulling seat 220 and the molding part 250 move obliquely along the guidance of the guiding assembly 230. With the further opening of the mold, the molding part 250 is separated from the concave surface of the product. At this time, the core - pulling structure 2 stays on the front mold core 101 with the mold - opening action, without affecting the demolding of the product from the rear mold core 102, which is convenient for realizing full - automatic injection molding.
[0032] In some embodiments, Figure 3 , 4 As shown in , 6 and 9, the spring assembly 210 includes a limit rod 211 connected to the front mold core 101 and a spring body 212 sleeved on the upper part of the limit rod 211. The spring body 212 can be a compression spring, a nitrogen spring or other structures. The limit rod 211 includes a rod limit block 213 located at the bottom of the limit rod 211. The rod limit block 213 and the through groove structure 214 are spaced apart by a preset distance. The preset distance between the limit block and the bottom of the core pull seat 220 is the maximum distance of the spring stretching. The preset distance is determined by those skilled in the art according to actual conditions, and is convenient for limiting the stretching range of the spring to ensure that the spring moves within a safe working range. The core pull seat 220 is provided with a spring assembly 21 0 matches the through slot structure 214, the limiting pull rod 211 is slidably connected with the through slot structure 214, the spring body 212 is limited to be compressed and released in the space matching with it in the upper part of the through slot structure 214, the spring body 212 is sleeved on the outside of the limiting pull rod 211, and does not affect the limiting pull rod 211 sliding through the spring body 212 in the through slot structure 214. The lower part of the through slot structure 214 may have a sliding through slot matching with the limiting block, so as to increase the sliding space for the limiting pull rod 211 and further save the mold space. The sliding distance of the limiting block relative to the core pulling seat 220 is the maximum distance of the spring stretching, and is also the maximum distance of the core pulling stroke of the core pulling seat 220, which is convenient for limiting the core pulling stroke.
[0033] In some embodiments, Figure 5 , 6 As shown in Figures 10 and 11, the hook assembly 240 includes a first hook structure 241 arranged on the rear mold core 102 and a second hook structure 242 arranged on the core pulling seat 220 and abutting against the first hook structure 241. The hook assembly 240 realizes the pulling and resetting action of the core pulling structure 2. The hook assemblies 240 arranged on the same core pulling seat 220 can be set as one group or more according to the size of the core pulling seat 220. Multiple groups of hook assemblies 240 provide greater mold opening force. When opening the mold, the second hook structure 242 pulls the first hook structure 241 abutting against it, and the core pulling seat 220 is pulled accordingly. The pulling force provided by the hook assembly 240 facilitates the core pulling of the forming part 250 under the guidance of the guide assembly 230.
[0034] Furthermore, if Figure 5 , 10As shown, the first hook structures 241 of the first core-pulling assembly 201 and the second core-pulling assembly 202 are both reverse L-shaped convex block structures, and the second hook structures 242 of the first core-pulling assembly 201 and the second core-pulling assembly 202 are both transverse block structures. The inner side surface of the first hook structure 241 abuts against the upper surface of the second hook structure 242. The core-pulling seats 220 of the first core-pulling assembly 201 and the second core-pulling assembly 202 are both provided with first grooves 243 that cooperate with the first hook structures 241 above the second hook structures 242. The inner side surface of the reverse L-shaped convex block structure of the first hook structure 241 can well abut against and tighten the upper surface of the transverse block structure of the second hook structure 242 during mold opening. As the mold opening action occurs, the hook assemblies 240 are tightened with each other to provide a stable and uniform core-pulling force for the core-pulling seats 220 connected to the second hook structures 242. The setting of the first grooves 243 facilitates the smooth detachment of the first hook structures 241 when the core-pulling seats 220 drive the second hook structures 242 to move horizontally. The concave structure is convenient for saving mold space.
[0035] Furthermore, as Figure 6 、 11 shown, the first hook structure 241 of the third core-pulling assembly 203 is a reverse L-shaped convex block structure, and the second hook structure 242 of the third core-pulling assembly 203 is an L-shaped convex block structure. Among them, the inner side surface of the first hook structure 241 abuts against the inner side surface of the second hook structure 242. The inner side surface of the reverse L-shaped convex block structure of the first hook structure 241 can well be internally buckled and tightened with the inner side surface of the L-shaped convex block structure of the second hook structure 242 during mold opening. As the mold opening action occurs, the hook assemblies 240 are tightened with each other to provide a stable and uniform core-pulling force for the core-pulling seats 220 connected to the second hook structures 242. The double L-shaped setting is easy to manufacture and maintain.
[0036] In some embodiments, as Figure 3 、 7As shown, the limiting structure 260 includes a core-pulling seat limiting block 261 disposed on one side of the core-pulling seat 220 and connected to the front mold core 101. The core-pulling seat 220 is provided with a second groove 262 that cooperates with the core-pulling seat limiting block 261. Specifically, the core-pulling seat limiting block 261 is disposed outside the core-pulling seat 220 and connected to the front mold. When the mold is opened, the lateral movement of the core-pulling seat 220 leans towards the core-pulling seat limiting block 261, causing the core-pulling seat limiting block 261 to penetrate into the second groove 262 and abut against the side wall of the core-pulling seat 220. The core-pulling seat limiting block 261 can limit the lateral travel distance of the core-pulling seat 220 during the core-pulling process, prevent the core-pulling seat 220 from over-traveling, protect the core-pulling structure 2 and the mold. When the core-pulling seat 220 is ejected by the spring assembly 210, the core-pulling seat limiting block 261 moves within the second groove 262 and abuts against the side wall of the core-pulling seat 220, which can play a role in limiting and supporting, and can limit the downward travel distance of the core-pulling seat 220. The core-pulling seat limiting block 261 and the spring assembly 210 together play an auxiliary mold-opening effect and improve the stability of the core-pulling structure 2.
[0037] In some embodiments, as Figure 3 、 7 shown, the guiding assemblies 230 of the first core-pulling assembly 201 and the second core-pulling assembly 202 both include a first guiding structure 2301 that is relatively disposed on both sides of the core-pulling seat 220 and is slidably connected to the core-pulling seat 220, and a second guiding structure 2302 that is disposed on the side of the core-pulling seat 220 opposite to the forming portion 250 and is slidably connected to the core-pulling seat 220. The side surface of the core-pulling seat 220 is provided with a first guiding groove 2303 that cooperates with the first guiding structure 2301 and a second guiding groove 2304 that cooperates with the second guiding structure 2302. The first guiding structure 2301 is disposed on both sides of the core-pulling seat 220, that is, at least two oppositely disposed guiding structures. The mutual cooperation between the first guiding structure 2301 and the first guiding groove 2303 provides uniform and stable guiding for both sides of the core-pulling seat 220. The second guiding structure 2302 is disposed opposite to the forming portion 250, and one or more can be provided according to the size of the core-pulling seat 220. In cooperation with the second guiding groove 2304, the forming portion 250 can be accurately and stably demolded under guiding. The guiding structure and the guiding groove can be structures such as a slider and a groove, a guide block and a through groove, etc. The guiding groove can be a dovetail groove, a T-shaped groove, etc. The guiding assembly 230 ensures that the core-pulling seat 220 can move precisely along a predetermined path. The design of multiple guiding structures enables the core-pulling seat 220 to perform core-pulling more stably and precisely, reduces vibration and offset during the core-pulling process, and improves the precision and quality of the product.
[0038] Furthermore, as Figure 3 、 7As shown, the first guiding structure 2301 includes a first inclined convex block 2305 slidably connected to the core pulling seat 220. The second guiding structure 2302 includes a T-shaped second inclined convex block 2306 slidably connected to the core pulling seat 220. The front parts of the first inclined convex block 2305 and the second inclined convex block 2306 are inclined downward from top to bottom in a direction away from the molding part 250. The guiding structures of the first guiding structure 2301 are relatively arranged on both sides of the core pulling seat 220, and the first inclined convex block 2305 is provided in the direction towards the core pulling seat 220, which facilitates the smooth core pulling of the side part of the core pulling seat 220 during the opening and closing process under the cooperation of the first inclined convex block 2305 and the first guiding groove 2303. The second inclined convex block 2306 is a T-shaped one extending into the core pulling seat 220. Extending into the core pulling seat 220 can more stably pull the core pulling seat 220 for core pulling, facilitate guiding the core pulling of the molding part 250, reduce the vibration and offset during the core pulling process, and improve the precision and quality of the product.
[0039] In some embodiments, as Figure 3 , 8 shown, the third core pulling assembly 203 includes a first core pulling seat 221 and a second core pulling seat 222. The guiding assembly 230 of the third core pulling assembly 203 includes a third guiding structure 2307 slidably connected to one side of the first core pulling seat 221, a fourth guiding structure 2308 slidably connected to one side of the second core pulling seat 222, and a fifth guiding structure 2309 slidably connected to one side of the first core pulling seat 221 and the second core pulling seat 222. The side of the first core pulling seat 221 is provided with a third guiding groove 2310 cooperating with the third guiding structure 2307 and a fourth guiding groove 2311 cooperating with the fifth guiding structure 2309. The side of the second core pulling seat 222 is provided with a fifth guiding groove 2312 cooperating with the fourth guiding structure 2308 and a sixth guiding groove 2313 cooperating with the fifth guiding structure 2309. The fifth guiding structure 2309 is slidably connected to the first core pulling seat 221 and the second core pulling seat 222 respectively. Thus, during core pulling, the fifth guiding structure 2309 can drive the first core pulling seat 221 and the second core pulling seat 222 to perform core pulling and demolding. The third guiding structure 2307 and the fourth guiding structure 2308 on both sides of the first core pulling seat 221 and the second core pulling seat 222 provide uniform and stable guiding for the outside. The guiding structure and the guiding groove can be structures such as a sliding block and a groove, a guiding block and a through groove, etc. The cooperation of the linkage between each guiding structure and its respective matching guiding groove ensures that the first core pulling seat 221 and the second core pulling seat 222 can move precisely along a predetermined path and perform core pulling more stably and precisely.
[0040] Furthermore, as Figure 3 , 8As shown, the third guiding structure 2307 includes a third inclined convex block 2314 slidably connected to the first core-pulling seat 221. The fourth guiding structure 2308 includes a fourth inclined convex block 2315 slidably connected to the second core-pulling seat 222. The fifth guiding structure 2309 includes a fifth inclined convex block 2316 slidably connected to the first core-pulling seat 221 and a sixth inclined convex block 2317 slidably connected to the second core-pulling seat 222. The third inclined convex block 2314, the fourth inclined convex block 2315, the fifth inclined convex block 2316 and the sixth inclined convex block 2317 are all inclined downward away from the molding part 250. Specifically, the fifth guiding structure 2309 can be arranged in the middle between the first core-pulling seat 221 and the second core-pulling seat 222. The fifth inclined convex block 2316 and the sixth inclined convex block 2317 are respectively arranged on the left and right sides of the fifth guiding structure 2309. The linkage core-pulling simplifies the core-pulling structure 2 on the two sides of the product and facilitates guiding the core-pulling of the molding part 250.
