[0029] The present utility model provides the following description with reference to the drawings to help 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 assist in 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.
[0030] In the description of the present utility model, directional descriptions are involved. For example, the directions or positional relationships indicated by up, down, front, back, left, right, etc. are based on the directions 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 direction, be constructed and operated in a specific direction, and thus cannot be construed as a limitation to the present utility model.
[0031] It should be understood that when an element (e.g., the first element) is "connected" to another element (e.g., the second element), the element can be directly connected to the other element, or there can be an intermediate element (e.g., the third element) between the element and the other element.
[0032] An embodiment of the present utility model provides a product mold for an automotive front sealing bracket. Figures 1 - 10 As shown, 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 slant elastic core-pulling assembly 2 is provided between the front mold core 101 and the rear mold core 102. The slant elastic core-pulling assembly 2 includes a first core-pulling assembly 201 and a second core-pulling assembly 202, as Figure 1The front part of the automotive front seal bracket product 3 shown has a plurality of groove structures 301 with concave surfaces, and the middle part has two protruding hole structures 302. The first core-pulling assembly 201 and the second core-pulling assembly 202 are respectively used for forming and core-pulling of the groove structure 301 and the hole structure 302. Both the first core-pulling assembly 201 and the second core-pulling assembly 202 include at least one set of spring assemblies 210 arranged on the front mold core 101, a core-pulling seat 220 connected to the spring assemblies 210, a forming part 230 arranged on the core-pulling seat 220, a hook assembly 240 connected to the bottom of the core-pulling seat 220, and a guiding assembly 250 arranged on one side of the core-pulling seat 220. The hook assembly 240 and the spring assemblies 210 are used to drive the core-pulling seat 220 and the forming part 230 to demold under the guidance of the guiding assembly 250. When the core-pulling seat 220 is relatively large, multiple spring assemblies 210 are required to provide the driving force. The spring assemblies 210 are slidably connected inside the core-pulling seat 220. The forming part 230 can be integrally arranged with the core-pulling seat 220 or fixed to the core-pulling seat 220 in the form of an insert. When the mold is closed, the spring assemblies 210 inside the inclined spring core-pulling assembly 2 are in a compressed state. When the mold starts to open, the compressed state of the spring begins to be released, and the hook assembly 240 is pulled by the fixed mold, so that the components connected such as the core-pulling seat 220 and the forming part 230 move obliquely along with the guidance of the guiding assembly 250. As the mold is further opened, the forming part 230 disengages from the groove structure 301 and the hole structure 302 respectively. At this time, the inclined spring core-pulling assembly 2 remains on the front mold core 101 with the mold opening action, without affecting the demolding of the product from the rear mold core 102, facilitating the realization of fully automatic injection molding.
[0033] In some embodiments, as Figure 3 shown, the inclined spring core-pulling assembly 2 includes a third core-pulling assembly 203 arranged mirror-symmetrically with the first core-pulling assembly 201 and a fourth core-pulling assembly 204 arranged mirror-symmetrically with the second core-pulling assembly 202. The automotive front seal bracket product 3 is generally provided on both the left and right sides of the vehicle. The mirror-symmetric arrangement can injection-mold a pair of left and right components of the automotive front seal bracket product 3 at one time, facilitating packaging and sales.
[0034] In some embodiments, as Figures 6a - 7b shown, the spring assembly 210 includes a limit pull rod 211 connected to the front mold core 101 and a spring body 212 sleeved on the outer side of the upper part of the limit pull rod 211, which facilitates the sliding of the limit pull rod 211 when the spring is compressed. The spring body 212 can be a compression spring, a nitrogen spring, or other structures. The limit pull rod 211 includes a limit block 213 arranged at the bottom of the limit pull rod 211, which is convenient for limiting the compression and stretching of the spring and ensuring that the spring moves within a safe working range.
[0035] Furthermore, as Figures 6a - 7bAs shown, the core puller 220 is provided with a through groove structure 221, and the through groove structure 221 includes a first through groove 222 located at the upper part of the through groove structure 221 and matched with the spring body 212, and a second through groove 223 located at the lower part of the through groove structure 221 and matched with the limiting pull rod 211. The spring body 212 is placed in the first through groove 222, and the limiting pull rod 211 passes through the spring body 212 upward from the second through groove 223 and is connected to the front mold core 101. The spring body 212 is limited in the second through groove 223 for compression and release. 212 is arranged on the outside of the limit rod 211, and does not affect the limit rod 211 sliding through the spring body 212 in the first through groove 222 and the second through groove 223. The limit block 213 is spaced a preset distance from the bottom of the core pulling seat 220, and the width of the limit block 213 is greater than the width of the second through groove 223. The preset distance between the limit block 213 and the bottom of the core pulling seat 220 is the maximum distance of the spring stretching. The preset distance is determined by technicians in this field according to actual conditions, 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.
[0036] In some embodiments, Figures 6a - 7b , Figure 10 As shown, the hook assembly 240 includes a first hook structure 241 arranged on the rear mold core 102 and a second hook structure 242 fixed on the core pulling seat 220 and abutting against the first hook. The hook assembly 240 realizes the pulling and resetting action of the oblique elastic core pulling assembly 2. The hook assembly 240 can be one group or more. 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, and the core pulling seat 220 is pulled accordingly, which facilitates the core pulling of the forming part 230.
[0037] Furthermore, if Figure 10 As shown, the first hook structure 241 includes an inverted L-shaped first protrusion 243 located at the top, and the second hook structure 242 includes an L-shaped second protrusion 244 located at the bottom. The first protrusion 243 abuts against the inner side surface of the second protrusion 244. The first protrusion 243 and the second protrusion 244 can provide a stable and uniform core pulling force, and the L-shaped setting is easy to manufacture and maintain.
[0038] In some embodiments, Figures 8 - 9 As shown, the guide assembly 250 includes a first guide structure 251 arranged on one side of the core pulling seat 220, a second guide structure 252 arranged opposite to the first guide structure 251, and a third guide structure 253 arranged on one side of the first guide structure 251 and the second guide structure 252. The guide assembly 250 ensures that the core pulling seat 220 moves accurately along a predetermined path. The design of multiple guide structures can make the core pulling seat 220 more stable and accurate in core pulling, reduce vibration and deviation during the core pulling process, and improve the accuracy and quality of the product.
[0039] Further, as Figures 8 - 9 shown, a first inclined convex block 254 is provided on one side of the first guiding structure 251 close to the core pulling seat 220, a second inclined convex block 255 is provided on one side of the second guiding structure 252 close to the core pulling seat 220, and a third inclined convex block 256 is provided on one side of the third guiding structure 253 close to the core pulling seat 220. The first inclined convex block 254, the second inclined convex block 255, and the third inclined convex block 256 all incline downward from top to bottom in a direction away from the molding part 2301. The first inclined convex block 254 and the second inclined convex block 255 facilitate the alignment of the side part of the mold during the opening and closing process. Specifically, the inclination angle of the third inclined convex block 256 is the same as the inclination angle of the spring assembly 210, which facilitates guiding the core pulling of the molding part 230, helps reduce the internal stress and defects of the product, and improves the overall quality of the product.
[0040] In some embodiments, as Figures 8 - 9 shown, a first groove 224 matching the first guiding structure 251, a second groove 225 matching the second guiding structure 252, and a third groove 226 matching the third guiding structure 253 are provided on the side surface of the core pulling seat 220. The chute provides precise guidance for the core pulling mechanism, ensures the smooth and accurate core pulling action, and prevents deviation during the core pulling process.
[0041] In some embodiments, as Figures 6a - 7b shown, the bottom of the core pulling seat 220 inclines downward toward the molding part 230. By being placed obliquely, a longer core pulling distance can be achieved within a shorter core pulling stroke, and it can also prevent the core pulling seat 220 from sliding backward and disengaging from the mold, enhancing the reliability of the inclined spring core pulling assembly 2 during mold closing.
[0042] The terms and words used in the above description and claims are not limited to their literal meanings, but are only used by the applicant to enable a clear and consistent understanding of the present utility model. Therefore, those skilled in the art should clearly understand that the above description of various embodiments of the present utility model is only for illustration, rather than for limiting the present utility model as defined by the appended claims and their equivalents.
