Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] like Figures 1-5 As shown, this utility model provides a mold structure for lateral core pulling and thread pulling of pipe connector products, including a core pulling and thread pulling mechanism. The core pulling and thread pulling mechanism includes a first sliding assembly, a second sliding member 3, a thread pulling insert 4, a first driving member, and a second driving member. The thread pulling insert 4 is sleeved on the first sliding assembly, and its external thread section 401 is located in the cavity 1401 of the B plate 13 of the lower mold, corresponding to the thread position of the product. The second driving member is used to drive the thread pulling insert 4 to perform thread pulling action. The second sliding member 3 is sleeved on the thread pulling insert 4 and the first sliding assembly, and its end has a forming groove 302 communicating with the cavity 1401, which is used to form the end structure of the product during injection molding. The first driving member is used to drive the first sliding assembly, the second sliding member 3, and the thread pulling insert 4 to perform core pulling action.

[0029] Through the coordinated action of the first positioning component, the second positioning element 3, the threaded insert 4, the first driving element, and the second driving element, the first positioning component is used to position and support the threaded insert 4 and the second positioning element 3. The second driving element drives the threaded insert 4 to perform threading action to form the threaded part of the product. The first driving element drives the first positioning component to drive the second positioning element 3 and the threaded insert 4 to perform core pulling action, thereby automating the threading and core pulling actions, improving the stability and consistency of the product, and at the same time, improving production efficiency and reducing labor costs.

[0030] As an optional implementation, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the second driving component includes a servo motor 8 and a gear assembly. The gear assembly includes a mounting base 9, a first gear 10, and a second gear 11. The mounting base 9 is disposed on the B plate 13 and is used to accommodate the first gear 10 and the second gear 11. The servo motor 8 is connected to the first gear 10 in a transmission manner. The first gear 10 and the second gear 11 mesh. The first positioning component passes through the shaft hole of the second gear 11 and is connected by a flat key 201.

[0031] The servo motor 8 serves as a power source, providing rotational power for the coiling insert 4 to perform coiling actions, and adjusting its speed and direction of rotation.

[0032] Mounting base 9 is used to mount and accommodate the first gear 10 and the second gear 11.

[0033] The servo motor 8 starts, driving the first gear 10 to rotate. Since the first gear 10 meshes with the second gear 11, power is transmitted to the second gear 11, which in turn drives the first sliding assembly to rotate, causing the threaded insert 4 to perform threading action within the cavity 1401. The external thread section 401 of the threaded insert 4 corresponds to the thread position of the product, forming the required thread structure through rotation.

[0034] As an optional implementation, such as Figure 2 , Figure 3 , Figure 4 As shown, the driving component includes a hydraulic cylinder 5, a slider 6, and a slide groove 7. The hydraulic cylinder 5 is connected to the slider 6 in a transmission manner, driving the slider 6 to move the first positioning component within the slide groove 7.

[0035] The hydraulic cylinder 5 serves as a power source, providing power for the core-pulling action of the first sliding assembly, the second sliding component 3, and the coiled insert 4.

[0036] When the hydraulic cylinder 5 is activated, it drives the slider 6 to move linearly along the slide groove 7, which in turn pulls the first positioning component and the threaded insert 4 out of the cavity 1401. During the core pulling process, the second positioning component 3 also separates from the product.

[0037] When the next injection molding operation is required, the hydraulic cylinder 5 drives the first sliding assembly, the second sliding component 3 and the threaded insert 4 to reset so that the next core pulling action can be performed.

[0038] As an optional implementation, a guide rail is provided in the slide groove 7, and a guide protrusion 601 is provided on the slider 6 to slide in cooperation with the guide rail.

[0039] Furthermore, guide rails are provided on the side wall or bottom of the chute 7.

[0040] The sliding engagement between the guide protrusion 601 of the slider 6 and the guide rail ensures that the slider 6 moves smoothly and precisely during its movement.

[0041] As an optional implementation, such as Figure 3 , Figure 4 , Figure 5 As shown, the first positioning assembly includes a first positioning rod 1 and a first positioning sleeve 2. The first end of the first positioning rod 1 is connected to the slider 6, and the second end of the first positioning rod 1 extends into the cavity 1401 to serve as part of the core of the internal structure of the T-type pipe connector product. The first positioning sleeve 2 is sleeved on the first positioning rod 1, and a flat key 201 is provided on its outer wall. A keyway 1101 adapted to the flat key 201 is provided on the shaft hole of the second gear 11. A square groove 202 is provided on the first end of the first positioning sleeve 2 near the threaded insert 4, and a square insert 402 adapted to the square groove 202 is provided on the threaded insert 4.

[0042] Furthermore, the coiled insert 4 has a channel 403 for the first moving rod 1 to pass through, so as to avoid interference with the first moving rod.

[0043] The first positioning sleeve 2 is T-shaped, with its large end located inside the slider 6 and connected to the slider 6 via a rotating connector, so that the first positioning sleeve 2 can rotate relative to the slider 6.

[0044] The square slot 202 and the square insert 402 are engaged to securely connect the first sliding sleeve 2 and the threaded insert 4 together, preventing relative rotation between them. Simultaneously, the keyway 1101 and the flat key 201 are connected to enable a transmission connection between the first sliding sleeve 2 and the second gear 11, allowing the first sliding sleeve 2 to move axially relative to the second gear 11, thus performing a core-pulling action.

[0045] The servo motor 8 starts, driving the first gear 10 to rotate. Due to the meshing of the first gear 10 and the second gear 11, power is transmitted to the second gear 11. Through the engagement of the flat key 201 and the keyway 1101, the first sliding sleeve 2 is driven to rotate, causing the threaded insert 4 to perform threading within the cavity 1401. The external thread section 401 of the threaded insert 4 corresponds to the thread position of the product, forming the required thread structure through rotation.

[0046] When the hydraulic cylinder 5 is activated, it drives the slider 6 to move linearly along the slide groove 7, which in turn causes the first sliding rod 1, the first sliding sleeve 2, and the threaded insert 4 to be pulled out from the cavity 1401. During the core pulling process, the second sliding component 3 is also separated from the product.

[0047] The second positioning component 3 is provided with T-shaped limiting guide rails 15 on both sides, and the second positioning component 3 is provided with limiting protrusions 303 that are adapted to the vertical section of the limiting guide rail 15. The horizontal section of the limiting guide rail 15 is used to limit the position of the second positioning component 3, and the vertical section of the limiting guide rail 15 is used to guide the second positioning component 3 to move along a preset path.

[0048] As an optional implementation, such as Figure 4 As shown, the second positioning component 3 has an installation groove for installing the first positioning sleeve 2 and the coiled tooth insert 4; the first positioning sleeve 2 and the coiled tooth insert 4 are respectively connected to the installation groove through a rotating connector.

[0049] Furthermore, the shape of the mounting groove is adapted to the outer contour of the first row sleeve 2 and the coiled insert 4.

[0050] This configuration ensures that the displacement movements of the first moving rod 1, the first moving sleeve 2, the threaded insert 4, and the second moving component 3 are synchronized during the core-pulling process, and that the first moving sleeve 2 and the threaded insert 4 can rotate relative to the first moving rod 1 and the second moving component 3 during the thread-pulling process.

[0051] As an optional implementation, such as Figure 3 , Figure 4 , Figure 5 As shown, the second end of the first positioning rod 1 is an arc surface 101, which abuts against the outer wall of other cores.

[0052] This setting, such as Figure 6 As shown, this enables precise molding of the internal structure of the T-type pipe connector product.

[0053] As an optional implementation, such as Figure 2 As shown, a stop block 1201 is provided on the A plate 12 of the upper mold. During the injection molding process, the stop block 1201 is located between the second slide member 3 and the mounting base 9 and abuts against both.

[0054] Furthermore, the contact surface between the second positioning member 3 and the stop block 1201 is a V-shaped surface 301, and the stop block 1201 is provided with a V-shaped groove 12011 that matches the V-shaped surface 301.

[0055] During the injection molding process, the two flat sides of the baffle 1201 abut against the mounting base 9 and the cavity component 14 respectively, and the V-groove 12011 of the baffle abuts against the V-surface 301 of the second sliding component 3, increasing the contact area between the two, improving contact stability, and preventing the second sliding component 3 from moving under force during the injection molding process, which would cause the product to have burrs.
