Description

Technical Field

[0001] This application relates to the field of mold manufacturing technology, and in particular to a nut hot pressing device and a mold fitting system. Background Technology

[0002] In the production of resin molds, molds are often made through thermoforming. For example, using thermoplastic plastic as raw material, the molten material is melted and then injected into a 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 with other structures. Inserts are generally placed either before or after mold forming.

[0004] Pre-molding insertion refers to the process where inserts are placed into the mold cavity in advance by workers or other automated assembly methods. In this method, the injection of molten material requires waiting for the inserts to be placed, resulting in low production efficiency.

[0005] The "molding after molding" method refers to first molding the mold, then heating the nut with a hot press device and pressing it into the mold. This method has gradually gained popularity because it does not affect the efficiency of mold molding.

[0006] In existing hot pressing devices, only one type of nut can generally be hot pressed. When different nuts need to be pressed into the mold, different equipment and different processes are required, which results in low production efficiency and high equipment costs. Utility Model Content

[0066] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a replaceable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application according to the specific circumstances.

[0067] Please see Figure 1 The first aspect of this application provides a nut hot pressing device, including: a device body 10, a nut conveying assembly 20, a hot pressing assembly 30, and a support assembly 40.

[0068] A support assembly 40 is disposed on the main body 10 of the device and is used to place the mold 50. The mold 50 is a thermoplastic material mold formed by injection molding or other methods and is to be fitted with a nut. The support assembly 40 may be provided with a locking member for placing and holding the mold 50; for example, if the mold is square, the locking member is a square groove.

[0069] The hot pressing assembly 30 includes multiple components, and the multiple hot pressing assemblies 30 are movably disposed on the main body 10 of the device; the hot pressing assembly 30 is used to heat the nut and press it into the mold 50; the nut conveying assembly 20 includes multiple components, 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 sizes; the nut conveying assembly 20 is used to convey the nut 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 drive the nut to press down, so as to press the nut into the preset position in the mold 50.

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

[0072] Furthermore, in some cases, multiple hot-pressing components 30 can operate simultaneously, further improving efficiency.

[0073] In one implementation, if multiple nuts need to be fitted into the mold 50, such as four nuts, two hot pressing components 30 can operate simultaneously. Specifically, after aligning the two hot pressing components 40 with the two hot pressing positions of the mold 50, two nuts are first hot-pressed into the mold 50. Then, the mold 50 or the hot pressing components 40 are moved so that the hot pressing components 40 are aligned with the other two positions of the mold 50, thereby hot-pressing the other two nuts into the mold 50.

[0074] In one implementation, if multiple nuts need to be fitted into the mold 50, and the multiple nuts have different models, for example, if two nuts need to be embedded in the mold 50, and they are a long nut and a short nut respectively, then the two hot pressing components 40 can load the long nut and the short nut respectively and press them into the mold 50 simultaneously.

[0075] The nut hot pressing device provided in this embodiment can hot press 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, the device body 10 is provided with a transverse slide rail 11 and a longitudinal slide rail 12; the hot pressing assembly 30 is slidably disposed on the transverse slide rail 11 along a first direction; the support assembly 40 is slidably disposed on the longitudinal slide rail 12 along a second direction; the first direction and the second direction are two mutually perpendicular directions in the horizontal direction.

[0077] In this embodiment, the first direction can be Figure 1 The X-axis direction; the second direction can be Figure 1 The Y-axis direction. 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] In one implementation, the hot-pressing positions on the mold 50 can be spaced apart along the second direction. After the hot-pressing assembly 40 aligns with one of the hot-pressing positions 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 delivery assembly 20 includes three components; the hot pressing assembly 30 includes three components; the three hot pressing assemblies 30 are respectively connected to the three nut delivery assemblies.

[0080] In practical applications, the inventors have found that most molds 50 require nuts to be pressed into both ends. Therefore, when operating, configuring two hot pressing components 30 to operate simultaneously provides the highest efficiency and cost-effectiveness.

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

[0082] Specifically, taking the existing molds to be fitted as a first mold and a second mold as an example; wherein, the first mold needs to press in a first nut and a second nut; the second mold needs to press in a first nut and a third nut. The three hot-pressing components 30 are, sequentially along a first direction, a first hot-pressing component 31, a second hot-pressing component 32, and a third hot-pressing component 33. In this embodiment, the first hot-pressing component 31 can be introduced with the second nut by the first nut conveying component 20, the second hot-pressing component 32 can be introduced with the first nut by the second nut conveying component 20, and the third hot-pressing component 33 can be introduced with the third nut conveying component 20. During operation, the simultaneous operation of the first hot-pressing component 31 and the second hot-pressing component 32 can press the second nut and the first nut into the first mold; the simultaneous operation of the second hot-pressing component 32 and the third hot-pressing component 33 can press the first nut and the third nut into the second mold.

[0083] Therefore, this embodiment can provide two different dual-nut synchronous hot pressing schemes for different molds 50 without changing the nut type, 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 rail 11 includes a first transverse slide rail 111 and a second transverse slide rail 112; the first transverse slide rail 111 is disposed in front of the second transverse slide rail 112 along a second direction; a first hot pressing assembly 31 and a third hot pressing assembly 33 are disposed on the first transverse slide rail 111; the second hot pressing assembly 32 is disposed on the second transverse slide rail 112; the second transverse slide rail 112 is movably disposed on the device body 10 along a second direction, for driving the second hot pressing assembly 32 to move to be flush with the first hot pressing assembly 31 or to move to be offset from the first hot pressing assembly 31 along the second direction.

[0085] In this design, the first transverse slide rail 111 provides guidance for the transverse movement of the first hot-pressing assembly 31 and the third hot-pressing assembly 33. The second transverse slide rail 112 provides guidance for the transverse movement of the second hot-pressing assembly 32.

[0086] Meanwhile, since the second hot pressing component 32 is disposed on the second transverse slide rail 112, the second hot pressing component 32 can move synchronously with the second transverse slide rail 112 when it moves along the second direction, so as to realize the alignment or staggered control of the second hot pressing component 32 with the first hot pressing component 31 and the third hot pressing component 33.

[0087] Specifically, taking the above-described embodiment as an example, a second nut, a first nut, and a third nut are respectively inserted into the first hot-pressing assembly 31, the second hot-pressing assembly 32, and the third hot-pressing assembly 33. When it is necessary to press the second nut and the third nut into the mold 50, the second transverse slide rail 112 can drive the second hot-pressing assembly 32 to move rearward along the second direction to offset the first hot-pressing assembly 31 and the third hot-pressing assembly 33. Then, the first hot-pressing assembly 31 and the third hot-pressing assembly 33 can work 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 rail 112 that can move along the second direction, more dual-nut synchronous hot-pressing schemes can be provided for the mold 50 with the same number of hot-pressing assemblies 30 and nut conveying assemblies 20.

[0088] It should be noted that a slide rail can be provided on the first transverse slide rail 111, and the first hot pressing assembly 31 and the third hot pressing assembly 33 can be slidably disposed within the slide rail of the first transverse slide rail 111. Similarly, a slide rail can be provided on the second transverse slide rail 112, and the second hot pressing assembly 32 can be slidably disposed within the slide rail of the second transverse slide rail 112. At the same time, a longitudinal slide rail 13 can be provided on the main body 10 of the device, and the second transverse slide rail 112 can be slidably disposed within the longitudinal slide rail 13.

[0089] In one embodiment, the main body 10 of the device may be equipped with a linear actuator such as a telescopic cylinder, so as to drive the first hot pressing assembly 31, the second hot pressing assembly 32 and the third hot pressing assembly 33 to move along the first direction and drive the second transverse slide rail 112 to move along the second direction.

[0090] In one embodiment provided in this application, the second transverse slide rail 112 is driven by a telescopic cylinder (not shown) to move along a 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 lead screw mechanism to move along a first direction.

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

[0092] In this embodiment, the first clearance hole 311 serves to avoid the second lead screw 15, ensuring that the rotation of the second lead screw 15 does not affect the first hot-pressing assembly 31. The second clearance hole 331 serves to avoid the first lead screw 14, ensuring that the rotation of the first lead screw 14 does not affect the third hot-pressing assembly 33. Simultaneously, the front end of the second hot-pressing assembly 32 may be provided with a clearance opening 321 to simultaneously avoid the first transverse slide rail 111, the first lead screw 14, and the second lead screw 15.

[0093] Similarly, the rear end of the second hot-pressing assembly 32 can engage with the third lead screw (not shown in the figure) so that the second hot-pressing assembly 32 can move when the third lead screw rotates. The third lead 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 a clearance area (not shown in the figure) to avoid the third lead screw.

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

[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 mounted on the nut container 21; the arc-shaped track 23 has an opening 231 on its horizontal side; 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 nut to rotate and enter the arc-shaped track 23; the arc-shaped track 23 is used to convey the nut and cause nuts that do not conform to the preset posture to fall out from the opening 231.

[0096] In this embodiment, when the turntable 22 rotates, it can drive the nuts on its surface to move in the direction of rotation. For example... Figure 4 When rotated counterclockwise, the nut moves counterclockwise under the driving force of the turntable 22 and gradually enters the arc-shaped track 23. A spiral channel 211 can be provided inside 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 arc-shaped track 23 to guide it.

[0097] In this embodiment, the nut with the preset posture is a nut whose axis is parallel to the axis of the arc-shaped track 23. Since the opening 231 on the arc-shaped track 23 is a side opening, nuts whose axis is parallel to the axis of the arc-shaped track 23 can be transported along the arc-shaped track 23, while nuts whose axis is not parallel to the arc-shaped track 23 will fall off as pushed by other nuts. Therefore, the nut conveying assembly 20 provided in this embodiment can realize the directional input of nuts into the hot pressing assembly 30.

[0098] In one embodiment, the support component 40 includes two components; the two support components 40 are arranged side by side.

[0099] In practical applications, the two support components 40 can work alternately. For example, after multiple hot pressing components 30 have performed the fitting operation on the mold on one support component 40, they can be transferred to another support component 40 for the fitting operation. At this time, the worker or robot can remove the mold 50 from one support component 40 and reload it, thus achieving uninterrupted operation.

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

[0101] The robotic arm can be a multi-axis robotic arm as in the prior art, which can grasp the mold 50 by gripping. The specific details are not elaborated in this embodiment.

[0102] Furthermore, it also includes: a stacking platform; the stacking platform is located next to the nut hot pressing device; a robot arm is used to remove the fitted mold 50 from the support assembly 40 and place it on the stacking platform.

[0103] The above are merely preferred embodiments of this application and are not intended to limit the present invention. Although the present application has been described in detail with reference to examples, those skilled in the art can still modify the technical solutions described in the foregoing examples or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
