[0022] A forming mold for a bracket with a toothed ring structure according to an embodiment of the present invention has at least the following beneficial effects:

[0023] This invention, by setting a first slider, a second slider, and an inner support elastic element, ensures that during mold opening, the inclined transmission structure drives the first slider to move, causing the first core puller to move. This allows the center hole of the bracket center sleeve to be demolded first, while the second slider remains in its original position due to the action of the inner support elastic element, ensuring that the first core puller completes the core pulling process first.

[0024] By setting an outward push transmission structure, this utility model enables the first slider to drive the second slider to move outward after the first core pulling is completed and the first slider continues to move outward. This causes the second core pulling to move, thereby allowing the end face annular groove on the outer side of the bracket center sleeve to be demolded. This avoids the inner and outer surfaces of the center sleeve being demolded simultaneously, which would affect the dimensional quality and forming quality of the center sleeve.

[0038] The following describes, with reference to the accompanying drawings, a forming mold for a bracket with a toothed ring structure according to an embodiment of the present invention.

[0039] Reference Figures 2 to 6 The present invention aims to provide an embodiment of a forming mold for a bracket with a toothed ring structure, for the production of... Figure 1 The bracket shown has a toothed ring structure to improve demolding and enhance the forming quality and dimensional quality of the central sleeve 320 on the bracket.

[0040] In this embodiment, the molding die mainly includes a fixed mold module 100 and a moving mold module 110. The fixed mold module 100 is usually fixed on the injection molding machine and is provided with a glue injection port to facilitate the injection of fused plastic into the molding die. The moving mold module 110 is usually fixed on the movable part of the injection molding machine. Thus, by moving the moving mold module 110, the mold opening and closing operations are realized to achieve the molding and demolding of the injection molded product.

[0041] In some specific embodiments of this utility model, the fixed mold module 100 may be provided with a forming cavity, and the moving mold module 110 may be provided with a forming protrusion. The forming cavity is used to form the outer surface of the bracket, and the forming protrusion is used to form the inner surface of the bracket.

[0042] It is easy to understand that by setting a forming cavity in the fixed mold module 100, this embodiment can also shorten the path that the plastic flows through before entering the forming cavity, avoid premature cooling of the material, avoid affecting the injection filling quality, and at the same time, make full use of the space of the injection mold, which can help reduce the volume of the forming mold.

[0043] Reference Figure 2 and Figure 4In this embodiment, the forming mold further includes a side parting module 120. The side parting module 120 includes a first slider 130 and a second slider 140 disposed on the moving mold module 110. An oblique transmission structure 150 is disposed between the first slider 130 and the fixed mold module 100.

[0044] In this embodiment, there are two opposing side-parting modules 120, so that both ends of the bracket are formed with a central sleeve 320, a central hole 310, an end face annular groove 330, and an internal gear ring structure.

[0045] Specifically, the first slider 130 is provided with an oblique hole, and the fixed mold module 100 is provided with an oblique rod. The oblique rod slides through the oblique hole. Therefore, when the moving mold module 110 drives the first slider 130 away from the fixed mold module 100, the oblique hole and the oblique rod interact, causing the first oblique block to move away from the forming cavity at the same time, realizing side core pulling, so as to form a hole or tube position perpendicular to the mold opening and closing direction.

[0046] In addition, the first slider 130 is provided with a first core pull 131 for forming a central hole 310 inside the bracket center sleeve 320, the sliding direction of the second slider 140 is parallel to the sliding direction of the first slider 130, and the second slider 140 is provided with a second core pull 141 for forming an end face annular groove 330 outside the bracket center sleeve 320.

[0047] Furthermore, an inner push drive structure 160, an outer push drive structure 170, and an inner support elastic element 180 are provided between the first slider 130 and the second slider 140. The inner push drive structure 160 is used to drive the first slider 130 to move the second slider 140 closer to the molding cavity to meet the sealing and molding requirements during injection molding. The outer push drive structure 170 is used to drive the first slider 130 to move the second slider 140 away from the molding cavity to meet the demolding requirements of the finished product.

[0048] Therefore, during mold closing, the oblique transmission structure 150 and the internal push transmission structure 160 cooperate to bring the first slider 130 and the second slider 140 close to the forming protrusion, so that the first core pull 131, the second core pull 141, the forming cavity and the forming protrusion cooperate to form the forming cavity of the support.

[0049] When the mold is opened, the oblique transmission structure 150 and the external push transmission structure 170 cooperate to move the first slider 130 and the second slider 140 away from the forming protrusion. The inner support elastic element 180 acts between the first slider 130 and the second slider 140 so that the first slider 130 and the second slider 140 move sequentially and the first core puller 131 and the second core puller 141 are pulled out sequentially.

[0050] In summary, this embodiment, by setting a first slider 130, a second slider 140, and an inner support elastic element 180, ensures that during mold opening, the inclined transmission structure 150 will drive the first slider 130 to move, causing the first core puller 131 to move. This allows the center hole 310 of the bracket center sleeve 320 to be demolded first, while the second slider 140 will remain in its original position due to the action of the inner support elastic element 180, ensuring that the first core puller 131 completes core pulling first.

[0051] In this embodiment, by setting an outward push transmission structure 170, when the first core puller 131 completes core pulling and the first slider 130 continues to move outward, the first slider 130 can drive the second slider 140 to move outward through the outward push transmission structure 170, so that the second core puller 141 moves. Thus, the end face annular groove 330 on the outer side of the bracket center sleeve 320 completes demolding, avoiding the simultaneous demolding of the inner and outer surfaces of the center sleeve 320, which would affect the dimensional quality and forming quality of the center sleeve 320.

[0052] In some specific embodiments of this utility model, the first slider 130 and the second slider 140 can be configured with multiple sets of first core pullers 131 and second core pullers 141, thereby producing multiple brackets.

[0053] Reference Figure 4 and Figure 6 For the internal push transmission structure 160, the first slider 130 may be located in the groove 280 of the second slider 140. Therefore, the outer surface of the first slider 130 can push the inner surface of the second slider 140 to meet the need to push the second slider 140 closer to the forming cavity.

[0054] Specifically, the second slider 140 is provided with a groove 280 for accommodating the first slider 130. The groove 280 is open upwards and outwards towards the outside of the forming mold.

[0055] Reference Figure 5 For the outward push transmission structure 170, the first slider 130 may be located in the groove 280 of the second slider 140. At the same time, a limiting screw 290 is provided at the bottom of the groove 280 of the second slider 140. Therefore, when the first slider 130 moves in the opposite direction, the first slider 130 can abut against the limiting screw 290, thereby pushing the second slider 140 to move outward.

[0056] In some specific embodiments of this utility model, the first slider 130 may be provided with a limiting recess 300 that matches the limiting screw 290, thereby increasing the contact area and reducing the wear of the limiting screw 290.

[0057] At the same time, when the limit screw 290 is removed, it is also convenient to disassemble and maintain the first slider 130, such as to facilitate the replacement of the first core puller 131 and the second core puller 141.

[0058] In some specific embodiments of this utility model, the second core puller 141 may include an inner shoulder 190 for forming the end face of the center sleeve 320.

[0059] It is easy to understand that by setting the inner shoulder 190, this embodiment also allows the second pull core 141 to cover the center sleeve 320 of the bracket, so as to prevent the center sleeve 320 from moving when the first pull core 131 moves, thus ensuring product quality.

[0060] In some specific embodiments of this utility model, the second slider 140 may include a recess 200 for forming the side end face of the bracket, and the edge of the recess 200 may form the outer radius of the side end face of the bracket.

[0061] It is easy to understand that by setting the recessed portion 200, this embodiment also facilitates the formation of the external shape of the bracket, making the outer rounded corners of the bracket transition smoothly, improving the surface quality of the product, and at the same time, avoiding sharp edges on the forming mold and reducing mold wear.

[0062] If the fixed mold module 100 forms the outer rounded corner of the side end face of the bracket, the fixed mold module 100 needs to be machined into an acute angle. This acute angle will wear down quickly under the erosion of the injection molding material, affecting the forming quality of the bracket.

[0063] In some specific embodiments of this utility model, the second core puller 141 can be interference-fitted onto the second slider 140.

[0064] It is easy to understand that this embodiment reduces the installation difficulty of the second core puller 141 by interference fit, and at the same time, makes the second core puller 141 and the second slider 140 fit tightly, eliminating gaps and avoiding material overflow.

[0065] In some specific embodiments of this utility model, the second slider 140 may be provided with a through hole for installing the second pull core 141. Therefore, when the second pull core 141 is installed into the second slider 140, it can be done by striking the end of the second pull core 141, and when the second pull core 141 is removed, it can also be done by striking the other end of the second pull core 141.

[0066] Reference Figure 6 In some specific embodiments of this utility model, the first core puller 131 may include a first cylindrical section 210 for forming a central hole 310 and a second cylindrical section 220 coaxially connected to the first cylindrical section 210. The diameter of the second cylindrical section 220 is larger than that of the first cylindrical section 210. The inner shoulder 190 is an inner convex ring on the inner side of the second core puller 141, and the diameter of the second cylindrical section 220 is larger than the inner diameter of the inner convex ring.

[0067] It is easy to understand that by giving the first core pull 131 a first cylindrical segment 210 and a second cylindrical segment 220, this embodiment can increase the local diameter of the first core pull 131, improve the strength of the first core pull 131, and reduce the risk of the first core pull 131 breaking.

[0068] Meanwhile, since the diameter of the second cylindrical section 220 is larger than the inner diameter of the inner convex ring, an interlaced structure can be formed. On the one hand, the second cylindrical section 220 can support the inner convex ring and prevent it from breaking due to the impact of the injection molding material. On the other hand, it strengthens the seal between the first core puller 131 and the second core puller 141, reduces the occurrence of overflow, and reduces the wear between the first core puller 131 and the second core puller 141.

[0069] In some specific embodiments of this utility model, the first slider 130 may include a first block 230 and a second block 240 connected by threads. The first block 230 is provided with a slant transmission structure 150, and the second block 240 is provided with a mounting hole for mounting the first core puller 131. The first block 230 and the mounting hole cooperate to define one end of the first core puller 131.

[0070] It is easy to understand that in this embodiment, by dividing the first slider 130 into a first block 230 and a second block 240, they can be processed, assembled and replaced separately, reducing manufacturing difficulty and meeting usage needs. For example, the first block 230 is made of wear-resistant material, while the second block 240 is made of shock-absorbing material.

[0071] Moreover, it facilitates debugging during production to solve trial molding problems related to motion coordination, product dimensional accuracy, or forming quality.

[0072] In some specific embodiments of this utility model, a mold-locking inclined surface structure 250 may be provided between the first block 230 and the fixed mold module 100. The mold-locking inclined surface structure 250 includes an outer mold-locking inclined surface provided on the first block 230 and an inner mold-locking inclined surface provided on the fixed mold module 100.

[0073] It is easy to understand that, in this embodiment, by setting the clamping inclined surface structure 250, the first slider 130 and the second slider 140 are also subject to high-strength limiting to resist the strong internal pressure of the plastic material in the molding cavity and avoid the product's physical size from increasing. The increase in the product's physical size refers to the size change caused by the increase in the physical part of the product, not the increase in all the dimensions of the product.

[0074] In some specific embodiments of this utility model, the first block 230 may be provided with a first pad 260, which is used to form an outer locking mold slope.

[0075] It is easy to understand that, by setting the first pad 260 in this embodiment, it can be conveniently replaced by the first block 230 to contact the fixed mold module 100, thereby improving wear resistance and coping with the frequent opening and closing of injection molds.

[0076] In some specific embodiments of this utility model, a second pad can be provided at the bottom of the second slider 140, and the second pad is fixed to the moving mold module 110, thereby reducing the wear between the second slider 140 and the moving mold module 110 and protecting the second slider 140.

[0077] In some specific embodiments of this utility model, the second block 240 may be provided with a through hole 270, which is used to accommodate the inner support elastic member 180. The two ends of the inner support elastic member 180 abut against the first block 230 and the second slider 140.

[0078] It is easy to understand that by providing a through hole 270 in the second block 240, this embodiment also facilitates the formation of an installation space for the inner support elastic element 180, thereby reducing the installation difficulty of the inner support elastic element 180.
