Description

Technical Field

[0001] This utility model relates to the field of mold technology, and more specifically, to an arc-shaped support mold. Background Technology

[0002] Combination Figure 1 As shown, existing curved supports for plastic parts typically have an arc-shaped structure along their length to meet installation space and stress requirements. However, when multiple screw posts are arranged on the surface of the curved support, the first and second adjacent screw posts face different directions. Although this is beneficial for multi-directional connection and fixation, it will create lateral undercut structures in different directions during the molding process. This results in a restricted demolding path, increased difficulty in mold design and manufacturing, and a higher risk of damage to the plastic part or decreased dimensional accuracy, thereby affecting the product's assembly efficiency and service life. Summary of the Invention

[0003] To address the demolding interference problem caused by the different core-pulling directions of adjacent screw columns during the forming process of existing arc-shaped bracket molds, as well as the defects such as complex mold structure, difficult processing and assembly, and insufficient positioning accuracy, this utility model provides an arc-shaped bracket mold with reasonable structural design, smooth core pulling, and accurate positioning, so as to improve the forming efficiency of the mold and the product qualification rate.

[0004] The technical solution of this utility model is as follows:

[0005] An arc-shaped support mold includes a front mold assembly and a rear mold assembly;

[0006] The front mold assembly includes a front template, a hydraulic cylinder, a front mold slider, a slider seat, a first inclined pulling assembly, and a second inclined pulling assembly;

[0007] The hydraulic cylinder is mounted on the front template and drives the front mold slider to slide along the first direction on the front template. The front mold slider drives the slider seat to move along the mold opening direction through the inclined guide structure.

[0008] The first and second inclined core-pulling components are arranged along different core-pulling directions, and both can be synchronously driven by the slider seat to perform inclined core-pulling demolding of the first and second screw pillars respectively.

[0009] The rear mold assembly and the front mold assembly are joined to form a cavity for molding the arc-shaped bracket.

[0010] By adopting the above technical solution, this utility model can realize the synchronous oblique demolding of the first screw post and the second screw post arranged in different directions under the drive of the slider seat, avoiding the structural interference problem caused by different core pulling directions, while reducing the setting of independent drive mechanism and reducing mold manufacturing and maintenance costs.

[0011] According to one embodiment of this utility model, the inclined guide structure includes an inclined surface disposed on the front mold slider and a corresponding bottom surface of the slider seat. This structure can smoothly convert the linear driving force of the hydraulic cylinder into the moving force of the slider seat along the mold opening direction through the guiding cooperation of the inclined surface and the bottom surface, resulting in high motion transmission efficiency and a compact structure.

[0012] According to one embodiment of this utility model, a T-shaped groove is obliquely provided on the inclined surface, and a T-shaped block is provided on the slider seat to slide in conjunction with the T-shaped groove. This design can effectively prevent lateral swaying of the slider seat during the guiding process, thereby improving motion accuracy and the overall stability of the mold.

[0013] According to one embodiment of this utility model, the bottom of the T-shaped groove is provided with a positioning groove, and the T-shaped block is provided with a corresponding positioning protrusion. This fit enables precise positioning when the slider seat moves to a predetermined position, ensuring the consistency and repeatability of the core-pulling action.

[0014] According to one embodiment of the present invention, the first inclined pull assembly includes a first inclined pull seat and a first inclined pull rod. One end of the first inclined pull rod is slidably installed in the first inclined pull groove of the first inclined pull seat, and the other end extends into the parting surface of the front template for forming the first screw post.

[0015] According to one embodiment of the present invention, the second inclined pull assembly includes a second inclined pull seat and a second inclined pull rod. One end of the second inclined pull rod is slidably installed in the second inclined pull groove of the second inclined pull seat, and the other end extends into the parting surface of the front template for forming the second screw post.

[0016] According to one embodiment of this utility model, the slider seat is provided with guide posts extending along the mold opening direction, and the front template is provided with guide sleeves that slide in cooperation with the guide posts. This structure provides linear guidance during the reciprocating movement of the slider seat, reduces friction and offset, and improves operational stability.

[0017] According to one embodiment of the present invention, the slider seat is provided with mounting holes for mounting the guide post.

[0018] According to one embodiment of the present invention, the moving end of the hydraulic cylinder is fixedly connected to a vertical slider, and the front mold slider is provided with a vertical groove that slides and engages with the vertical slider.

[0019] According to one embodiment of the present invention, the rear mold assembly includes a rear template, a top plate, and an ejector pin. The ejector pin is used to eject the formed arc-shaped support when the mold opens. This ejection structure can effectively prevent the product from remaining in the cavity after mold opening, thus improving demolding efficiency. Attached Figure Description

[0041] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model. Example 1

[0042] Combination Figure 1 As shown in the figure, the surface of the arc-shaped bracket 10 is provided with multiple screw posts. Each pair of adjacent screw posts is a first screw post 11 and a second screw post 12, and the first screw post 11 and the second screw post 12 have different inclination angles.

[0043] like Figure 2-9 As shown, this embodiment discloses an arc-shaped bracket 10 mold, including a front mold assembly 20 and a rear mold assembly 30. The front mold assembly 20 and the rear mold assembly 30, when fitted together, form a cavity for molding the arc-shaped bracket 10. The arc-shaped bracket 10 is arc-shaped along its length, and its surface is provided with a plurality of adjacently arranged first screw posts 11 and second screw posts 12. The first screw posts 11 and second screw posts 12 have different core-pulling directions. The front mold assembly 20 includes a front template 21, a hydraulic cylinder 22, a front mold slider 23, a slider seat 24, a first inclined pulling assembly 25, and a second inclined pulling assembly 26. The hydraulic cylinder 22 is installed on the outside of the front template 21 and drives the front mold slider 23 to slide on the front template 21 along a first direction. The movement of the front mold slider 23 drives the slider seat 24 to move along the mold opening direction through an inclined guide structure, realizing the synchronous movement of the slider seat 24 during the mold opening and closing process. The first inclined pulling assembly 25 and the second inclined pulling assembly 26 are arranged along different core pulling directions, and both can be driven by the slider seat 24, so as to perform inclined pulling demolding of the first screw post 11 and the second screw post 12 respectively.

[0044] Furthermore, combined Figure 3-4As shown, the inclined guide structure includes an inclined surface 23a disposed on the front mold slider 23 and a bottom surface of a slider seat 24 that mates with the inclined surface 23a. A guide contact surface is formed between the inclined surface 23a and the bottom surface of the slider seat 24. When the hydraulic cylinder 22 drives the front mold slider 23 to move along the first direction, the contact between the inclined surface 23a and the bottom surface of the slider seat 24 causes the slider seat 24 to generate displacement along the mold opening direction while being subjected to lateral thrust, thereby converting the linear driving force of the hydraulic cylinder 22 into the driving force of the slider seat 24 along the mold opening direction. This structure features stable transmission and high mechanical conversion efficiency, and is also easy to manufacture and assemble.

[0045] Furthermore, combining Figure 5 As shown, a T-slot 23b is obliquely provided on the inclined surface 23a. A T-block 24a correspondingly is provided on the bottom surface of the slider seat 24, which slides in conjunction with the T-slot 23b. The T-block 24a can slide smoothly within the T-slot 23b and limit the offset of the slider seat 24 in the direction perpendicular to the mold opening direction and the first direction, ensuring the straightness accuracy of the slider seat 24 during the guiding process. The T-block 24a and the T-slot 23b adopt a transition fit or clearance fit, which not only ensures smooth movement but also facilitates later maintenance and replacement.

[0046] Furthermore, combining Figure 6 As shown, the bottom of the T-shaped groove 23b is provided with a positioning groove 23c, and the T-shaped block 24a on the slider seat 24 is provided with a corresponding positioning protrusion 24b. The positioning groove 23c and the positioning protrusion 24b cooperate with each other when the slider seat 24 moves to the predetermined position to achieve precise positioning of the slider seat 24.

[0047] Furthermore, combined Figure 7 As shown, the first angled pull assembly 25 includes a first angled pull seat 251 and a first angled pull rod 252. The first angled pull seat 251 is fixedly mounted on the slider seat 24. One end of the first angled pull rod 252 is slidably mounted in the first angled pull groove 251a of the first angled pull seat 251, and the other end extends into the parting surface of the front mold plate 21, so as to form the shape of the first screw post 11 together with the cavity when the mold is closed. During the mold opening process, the slider seat 24 moves along the mold opening direction, driving the first angled pull rod 252 to move along the core pulling direction of the first screw post 11, thereby making the first screw post 11 easily demolded.

[0048] Furthermore, combined Figure 7As shown, the second angled pull assembly 26 includes a second angled pull seat 261 and a second angled pull rod 262. The second angled pull seat 261 is also fixedly mounted on the slider seat 24. One end of the second angled pull rod 262 is slidably mounted in the second angled pull groove 261a of the second angled pull seat 261, and the other end extends into the parting surface of the front template 21 for forming the second screw post 12. Similar to the first angled pull assembly 25, during mold opening, the second angled pull rod 262 moves in a different core-pulling direction than the first angled pull rod 252, thereby completing the demolding of the second screw post 12. This structure achieves synchronous core-pulling of screw posts in multiple directions, reducing the number of mold drive mechanisms.

[0049] Furthermore, the slider seat 24 is provided with multiple mounting slots 24d, one of which is used to install the first inclined drawer seat 251, and the other is used to install the second inclined drawer seat 261. The first inclined drawer slot 251a on the first inclined drawer seat 251 is an inclined sliding groove, and similarly, the second inclined drawer slot 261a on the second inclined drawer seat 261 is an inclined sliding groove.

[0050] Furthermore, combined Figure 3 As shown, the slider seat 24 is provided with a guide post 27 extending along the mold opening direction, and the front platen 21 is provided with a guide sleeve that slides and engages with the guide post 27. The sliding engagement between the guide post 27 and the guide sleeve ensures the straightness of the slider seat 24 when it moves along the mold opening direction, reduces friction, and avoids wear of parts due to offset.

[0051] Furthermore, combining Figure 4 As shown, the slider seat 24 is provided with mounting holes 24c for mounting guide posts 27. The mounting holes 24c and guide posts 27 are connected by interference fit or thread, which facilitates the installation and disassembly of guide posts 27 and allows for quick replacement when guide posts 27 are worn or damaged, reducing downtime.

[0052] Furthermore, combined Figure 5 As shown, a vertical slider 28 is fixedly connected to the moving end of the hydraulic cylinder 22, and a vertical groove 23d is provided on the front mold slider 23 to slide and engage with the vertical slider 28. The engagement between the vertical slider 28 and the vertical groove 23d provides additional guiding support when the hydraulic cylinder 22 drives the front mold slider 23 to move, preventing the front mold slider 23 from tilting or deviating during movement, thereby improving the stability of the transmission.

[0053] Furthermore, combined Figure 9 As shown, the rear mold assembly 30 includes a rear template 31, a top plate 32, and an ejector pin 33. The ejector pin 33 is used to eject the formed arc-shaped support 10 when the mold is opened.

[0054] In this embodiment, the mold opening step is as follows:

[0055] During mold closing, the front mold assembly 20 and the rear mold assembly 30 close to form the cavity of the arc-shaped support 10. The first inclined pull rod 252 and the second inclined pull rod 262 enter the parting surface to form the shapes of the first screw post 11 and the second screw post 12, respectively. After injection molding, the hydraulic cylinder 22 drives the front mold slider 23 to move along a first direction, which is perpendicular to the mold opening direction and faces outward from the mold. The front mold slider 23 drives the slider seat 24 to move along the mold opening direction through the inclined guide structure. The slider seat 24 simultaneously drives the first inclined pull assembly 25 and the second inclined pull assembly 26 to move along different core-pulling directions, so that the first screw post 11 and the second screw post 12 can be smoothly disengaged from the cavity, avoiding interference problems caused by different core-pulling directions. Subsequently, the rear mold assembly 30 separates from the front mold assembly 20, and the ejector pin 33 pushes out the arc-shaped support 10, achieving complete demolding. The entire process is smooth and precise, which can effectively improve the production efficiency of the mold and the molding quality of the product.
