Description

Technical Field

[0001] The present application relates to the technical field of mold manufacturing, and in particular to a nut hot pressing device and a mold fitting system. Background Art

[0002] In the production of resin molds, molds are often made through hot melt molding. For example, hot melt plastic is used as the raw material, which is melted and then injected into the mold cavity to form the desired mold.

[0003] In some molds, inserts such as nuts are added during the mold making process to facilitate assembly of the mold with other structures. Inserts can generally be added before or after the mold is formed.

[0004] Insertion before mold formation means that the insert is placed in the mold cavity in advance by the staff or other automated assembly methods. In this method, the injection of molten raw materials must wait for the insert to be placed, which reduces production efficiency.

[0005] The "mold-in-place" method involves first forming the mold, then heating the nut with a hot press and pressing it into the mold. This method is gaining popularity because it does not affect the efficiency of mold forming.

[0006] However, in existing hot pressing devices, only one type of nut can be hot pressed. When different nuts need to be pressed into the mold, different equipment and different processes need to be used separately, resulting in low production efficiency and high equipment costs.

[0067] See also Figure 1 In the first aspect of the embodiments of the present application, a nut hot pressing device is provided, including: a device body 10, a nut conveying assembly 20, a hot pressing assembly 30 and a support assembly 40.

[0068] The support assembly 40 is mounted on the device body 10 and is used to house the mold 50. The mold 50 is a thermoplastic mold, formed by injection molding or other methods, to be engaged with the nut. The support assembly 40 may be provided with a retaining member for positioning and securing the mold 50; for example, if the mold is square, the retaining member may be a square groove.

[0069] The hot pressing assembly 30 includes multiple hot pressing assemblies 30, and the multiple hot pressing assemblies 30 can be movably arranged on the device body 10; the hot pressing assembly 30 is used to heat the nuts and press them into the mold 50; the nut conveying assembly 20 includes multiple nut conveying assemblies 20, and the multiple nut conveying assemblies 20 are respectively connected to the multiple hot pressing assemblies 30; the multiple nut conveying assemblies 20 can hold nuts of different models; the nut conveying assembly 20 is used to convey the nuts to the hot pressing assembly 30.

[0070] In this embodiment, the hot pressing assembly 30 can use the hot pressing head in the prior art, which can heat the nut and then drive the nut to press down, so as to press the nut into a preset position in the mold 50.

[0071] In this embodiment, multiple nut conveying assemblies 20 can respectively convey nuts of different models to multiple hot pressing assemblies 30, so that when different nuts need to be hot pressed, the nut models can be switched by selecting different hot pressing assemblies 30 without going through the nut model changing operation, which can save the model changing time and improve work efficiency.

[0072] Furthermore, in some cases, multiple heat pressing assemblies 30 can operate synchronously to further improve efficiency.

[0073] As an embodiment, when multiple nuts need to be embedded in the mold 50, for example, 4 nuts need to be embedded, two hot pressing components 30 can operate simultaneously; the specific process can be that after the two hot pressing components 40 are aligned with the two hot pressing positions of the mold 50, 2 nuts are first hot pressed into the mold 50, and then the mold 50 or the hot pressing component 40 is moved so that the hot pressing component 40 is aligned with the other two of the mold 50, thereby hot pressing the other 2 nuts into the mold 50.

[0074] As an embodiment, when multiple nuts need to be embedded in the mold 50 and the multiple nuts have different models, for example, two nuts need to be embedded in the mold 50 and they are a long nut and a short nut respectively, the two hot pressing components 40 can be loaded with the long nut and the short nut respectively and then pressed into the mold 50 simultaneously.

[0075] The nut hot pressing device provided in this embodiment can realize hot pressing of nuts of different models on the same device, thereby effectively improving the applicability and production efficiency of the device.

[0076] In a more specific embodiment, a transverse slide rail 11 and a longitudinal slide rail 12 are provided on the device body 10; the hot pressing assembly 30 is slidably provided on the transverse slide rail 11 along a first direction; the support assembly 40 is slidably provided on the longitudinal slide rail 12 along a second direction; the first direction and the second direction are two directions perpendicular to each other in the horizontal direction.

[0077] In this embodiment, the first direction can be Figure 1 The X-axis direction in the second direction can be Figure 1 During operation, the hot pressing assembly 30 moves along the first direction and the support assembly 40 moves along the second direction to achieve alignment between the hot pressing assembly 30 and the support assembly 40.

[0078] As an embodiment, the hot pressing positions on the mold 50 can be spaced apart along the second direction. After the hot pressing assembly 40 is aligned with a hot pressing position at the end of the mold 50, it can press the heated nut into the mold 50. Then, the hot pressing assembly 40 rises, and the support assembly 40 drives the mold 50 to move along the second direction, so as to gradually press the nut into each hot pressing position.

[0079] In one embodiment, the nut conveying components 20 include three; the hot pressing components 30 include three; the three hot pressing components 30 are respectively connected to the three nut conveying components.

[0080] In actual applications, the inventors have found that nuts need to be pressed into both ends of most molds 50. Therefore, during operation, configuring two hot pressing assemblies 30 to operate synchronously has the highest efficiency and cost-effectiveness.

[0081] In this embodiment, the number of the nut conveying assemblies 20 is at least three, which can provide at least two different double-nut synchronous hot pressing schemes for the mold 50.

[0082] Specifically, take the example of the existing molds to be fitted being the first mold and the second mold; wherein, the first mold needs to press in the first nut and the second nut; and the second mold needs to press in the first nut and the third nut. The three hot pressing assemblies 30 are the first hot pressing assembly 31, the second hot pressing assembly 32, and the third hot pressing assembly 33 along the first direction. In this embodiment, the first hot pressing assembly 31 can be introduced into the second nut by the first nut conveying assembly 20, the second hot pressing assembly 32 can be introduced into the first nut by the second nut conveying assembly 20, and the third hot pressing assembly 33 can be introduced into the third nut by the third nut conveying assembly 20. During operation, the first hot pressing assembly 31 and the second hot pressing assembly 32 can be operated simultaneously to press the second nut and the first nut into the first mold; the second hot pressing assembly 32 and the third hot pressing assembly 33 can be operated simultaneously to press the first nut and the third nut into the second mold.

[0083] Therefore, this embodiment can provide two different double-nut synchronous hot pressing solutions for different molds 50 without changing the nut model, which can effectively improve the adaptability of the device in practical applications.

[0084] In one embodiment, please participate Figure 1 and Figure 2 The SPL transverse slide 11 includes a first transverse slide 111 and a second transverse slide 112; the first transverse slide 111 is arranged in front of the second transverse slide 112 along the second direction; the first hot pressing assembly 31 and the third hot pressing assembly 33 are arranged on the first transverse slide 111; the second hot pressing assembly 32 is arranged on the second transverse slide 112; the second transverse slide 112 is movably arranged on the device body 10 along the second direction, and is used to drive the second hot pressing assembly 32 to move to be flush with the first hot pressing assembly 31 or to move to be staggered with the first hot pressing assembly 31 along the second direction.

[0085] In this embodiment, the first transverse slide rail 111 is used to guide the transverse movement of the first hot pressing assembly 31 and the third hot pressing assembly 33 . The second transverse slide rail 112 is used to guide the transverse movement of the second hot pressing assembly 32 .

[0086] At the same time, since the second hot pressing assembly 32 is arranged on the second transverse slide rail 112, when the second transverse slide rail 112 moves along the second direction, the second hot pressing assembly 32 can follow the synchronous movement to achieve alignment or staggered control of the second hot pressing assembly 32 and the first hot pressing assembly 31 and the third hot pressing assembly 33.

[0087] Specifically, also taking the above-mentioned embodiment as an example, the second nut, the first nut, and the third nut are respectively introduced into the first hot pressing assembly 31, the second hot pressing assembly 32, and the third hot pressing assembly 33. When the second nut and the third nut need to be pressed into the mold 50, the second transverse slide 112 can drive the second hot pressing assembly 32 to move rearward along the second direction to stagger the first hot pressing assembly 31 and the third hot pressing assembly 33. After that, the first hot pressing assembly 31 and the third hot pressing assembly 33 can operate synchronously to press the second nut and the third nut into the mold 50. That is, in this embodiment, by using the second transverse slide 112 that can move along the second direction, it is possible to provide the mold 50 with more double-nut synchronous hot pressing solutions with the same number of hot pressing assemblies 30 and nut conveying assemblies 20.

[0088] It should be noted that a slide rail may be provided on the first transverse slide rail 111, and the first hot pressing assembly 31 and the third hot pressing assembly 33 may be slidably disposed within the slide rail of the first transverse slide rail 111.

Furthermore, a longitudinal slide rail 13 may be provided on the device body 10, and the second transverse slide rail 112 may be slidably disposed within the longitudinal slide rail 13.

[0089] As an embodiment, a linear drive such as a telescopic cylinder can be provided on the device body 10 to drive the first hot pressing assembly 31, the second hot pressing assembly 32 and the third hot pressing assembly 33 to move in the first direction and drive the second transverse slide rail 112 to move in the second direction through the linear drive.

[0090] In one embodiment provided herein, the second transverse slide rail 112 is driven by a telescopic cylinder (not shown) to move in the second direction. The first hot pressing assembly 31, the second hot pressing assembly 32, and the third hot pressing assembly 33 are driven by a screw mechanism to move in the first direction.

[0091] For details, please refer to Figure 2 and Figure 3 A first avoidance hole 311 is provided on the first hot pressing assembly 31; a second avoidance hole 331 is provided on the third hot pressing assembly 33; a first screw rod 14 and a second screw rod 15 that can rotate are provided on the device body 10; the first screw rod 14 is engaged with the first hot pressing assembly 31 and passes through the second avoidance hole 331; the second screw rod 15 is engaged with the third hot pressing assembly 33 and passes through the first avoidance hole 311.

[0092] In this embodiment, the first avoidance hole 311 provides a clearance for the second screw rod 15, ensuring that the rotation of the second screw rod 15 does not affect the first hot pressing assembly 31. The second avoidance hole 331 provides a clearance for the first screw rod 14, ensuring that the rotation of the first screw rod 14 does not affect the third hot pressing assembly 33. Furthermore, a clearance opening 321 can be provided at the front end of the second hot pressing assembly 32 to simultaneously clear the first transverse rail 111, the first screw rod 14, and the second screw rod 15.

[0093] Similarly, the rear end of the second hot-pressing assembly 32 can engage with a third screw (not shown in the figure) so that when the third screw rotates, it can drive the second hot-pressing assembly 32 to move. The third screw can be disposed on the second transverse slide rail 112, and the first hot-pressing assembly 31 and the third hot-pressing assembly 33 are also provided with an avoidance zone (not shown in the figure) to avoid the third screw.

[0094] In a more specific embodiment, the front ends of the first hot pressing assembly 31 and the third hot pressing assembly 33 along the second direction are connected to the first transverse slide rail 111 ; the rear end of the second hot pressing assembly 32 along the second direction is connected to the second transverse slide rail 112 .

[0095] In one embodiment provided in this application, please refer to Figure 1 、 Figure 4 and Figure 5 The nut conveying assembly 20 includes: a nut container 21, a turntable 22, an arc-shaped track 23 and a conveying pipe 24; the turntable 22 is rotatably arranged on the nut container 21; the arc-shaped track 23 is provided with an opening 231 along the side surface in the horizontal direction; the two ends of the arc-shaped track 23 are respectively connected to the turntable 22 and the conveying pipe 24; the conveying pipe 24 is connected to the hot pressing assembly 30; the turntable 22 is used to drive the nuts to rotate and enter the arc-shaped track 23; the arc-shaped track 23 is used to convey nuts and make nuts that do not conform to the preset posture fall from the opening 231.

[0096] In this embodiment, when the turntable 22 rotates, it can drive the nut on its surface to move along its rotation direction. Figure 4 When rotating counterclockwise, the nut will move counterclockwise under the driving force of the turntable 22 and gradually enter the curved track 23. A spiral channel 211 can be provided in the nut container 21. One end of the spiral channel 211 connects to the surface of the turntable 22 to allow the nut on the turntable 22 to enter the spiral channel 211. The other end of the spiral channel 211 connects to the curved track 23 to serve as a guide for the curved track 23.

[0097] In this embodiment, the nuts in the preset position are axially parallel to the axis of the curved track 23. Because the opening 231 in the curved track 23 is a side opening, nuts axially parallel to the axis of the curved track 23 can be transported along the curved track 23, while nuts axially non-parallel to the curved track 23 will fall due to the push of other nuts. Therefore, the nut conveying assembly 20 provided in this embodiment can achieve the directionally fed nuts into the hot pressing assembly 30.

[0098] In one embodiment, the support assembly 40 includes two support assemblies 40 ; the two support assemblies 40 are arranged in parallel.

[0099] In practical applications, the two support assemblies 40 can operate alternately. For example, multiple hot pressing assemblies 30 can perform the fitting operation on the mold on one support assembly 40 and then move to the other support assembly 40 to perform the fitting operation. At this time, the staff or robot can remove the mold 50 from one support assembly 40 and reload it, achieving uninterrupted operation.

[0100] The second aspect of the present application provides a mold fitting system, comprising: a robot and any one of the above-mentioned nut hot pressing devices; the robot is used to transfer the mold 50 to the support assembly 40 of the nut hot pressing device, and to remove the fitted mold 50 from the support assembly 40.

[0101] The robot arm may be a multi-axis robot arm in the prior art, which can grasp the mold 50 by clamping, and the details are not described in detail in this embodiment.

[0102] Furthermore, it also includes: a stacking table; the stacking table is arranged next to the nut hot pressing device; and a manipulator is used to remove the engaged mold 50 from the support assembly 40 and place it on the stacking table.

[0103] The above are only preferred embodiments of the present application and are not intended to limit the present invention.
