DETAILED DESCRIPTION

[0043] The following will be combined with the implementation of the utility model to clearly and completely describe the technical solutions in the implementation of the utility model. Obviously, the described implementation is only a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0044] like Figures 1 to 8 As shown, the mold nut assembly tool of the utility model includes a first carrier plate 1, a second carrier plate 2, an elastic member 3, a sleeve 4, an ejector rod 5, a positioning rod 6 and a support rod 7; it is used to assemble the nut 100 into the mold 200.

[0045] like Figure 1 , Figure 2 and Figure 7 As shown, the first carrier plate 1 and the second carrier plate 2 are stacked; the elastic member 3 is arranged between the first carrier plate 1 and the second carrier plate 2, and is used to buffer the relative displacement of the first carrier plate 1 and the second carrier plate 2; the sleeve 4 is arranged on the first carrier plate 1, and the sleeve 4 passes through the first carrier plate 1; the ejector rod 5 is arranged on the second carrier plate 2, and one end of the ejector rod 5 is inserted into the sleeve 4;

[0046] As in the above structure, during the application process, the nut 100 is placed in the sleeve 4, and the tooling is moved as a whole to the mold 200, and then moved toward the mold 200, so that the sleeve 4 corresponds to the limiting rod 400 preset on the mold 200. At this time, the sleeve 4 will abut the mold 200 to limit the first carrier 1, while the second carrier 2 can still move, which will compress the elastic member 3 and push the nut 100 onto the limiting rod 400. Then, the tooling is away from the mold 200, and the nut 100 remains on the limiting rod 400. After the injection molding is completed, the limiting rod 400 is detached, and the nut 100 remains in the injection molded part;

[0047] Specifically, a guide sleeve 300 is installed on the mold 200, and the limiting rod 400 is slidably matched with the guide sleeve 300 to ensure accurate positioning.

[0048] like Figures 6 to 8 As shown, the ejector rod 5 includes a syringe 51, a cover plate 52 and an anti-error rod 53, wherein the syringe 51 is arranged on the second carrier plate 2, and one end of the ejector rod 5 is inserted into the sleeve 4, and the inner wall of the syringe 51 is provided with a reduced diameter portion 501, and the inner diameter of the reduced diameter portion 501 is smaller than the inner diameter of other parts of the syringe 51; the cover plate 52 is arranged on the end of the syringe 51 away from the sleeve 4; the anti-error rod 53 is slidably arranged in the syringe 51, the middle section of the anti-error rod 53 is slidably matched with the reduced diameter portion 501, and the diameters of the two ends of the anti-error rod 53 are larger than the inner diameter of the reduced diameter portion 501;

[0049] As in the above structure, a movable anti-error rod 53 is provided in the ejector rod 5. Since the anti-error rod 53 is slidably matched with the reduced diameter portion 501 of the syringe 51 through the middle section, the anti-error rod 53 will not detach from the syringe 51. When the ejector rod 5 of this structure is adopted, the inner hole of the nut 100 will cooperate with the end of the anti-error rod 53; and when the nut 100 and the ejector rod 5 do not match, when the nut 100 is placed in the sleeve 4, it will be subject to resistance from the anti-error rod 53, which serves to remind the nut 100 to be placed incorrectly, so as to avoid the problem of misplacing the nut 100 when multiple sleeves 4 and multiple nuts 100 are used.

[0050] Specifically, the error-proofing rod 53 includes a bottom rod 531 and a top plate 532, wherein the bottom rod 531 is slidably matched with the reduced diameter portion 501; the top plate 532 is arranged on an end of the bottom rod 531 away from the sleeve 4; the diameter of the end of the bottom rod 531 close to the sleeve 4 and the top plate 532 is greater than the diameter of the reduced diameter portion 501;

[0051] As described above, the error-proofing rod 53 is composed of a bottom rod 531 and a top plate 532, so that the error-proofing rod 53 is conveniently assembled into the syringe 51 and the error-proofing rod 53 is matched with the reduced diameter portion 501 of the syringe 51;

[0052] Specifically, the bottom rod 531 and the top plate 532 are connected and fixed by fasteners such as bolts to facilitate assembly and disassembly.

[0053] like Figures 3 to 5 As shown, the elastic member 3 includes a slide bar 31 and a spring 32, wherein one end of the slide bar 31 is connected to the first carrier plate 1, and the other end passes through the second carrier plate 2; the spring 32 is sleeved on the slide bar 31, and one end of the spring 32 abuts against the first carrier plate 1, and the other end abuts against the second carrier plate 2;

[0054] As in the above structure, when the tooling is working, as the second carrier plate 2 moves toward the first carrier plate 1, it will compress the spring 32, and at the same time, the slide bar 31 and the second carrier plate 2 will slide together to achieve a guiding effect. After the nut pressing work is completed, as the tooling moves away from the mold, the first carrier plate 1 and the second carrier plate 2 will reset themselves under the action of the spring 32 to facilitate the next nut pressing work.

[0055] Specifically, the elastic member 3 further includes a sliding bearing 33, the sliding bearing 33 is disposed on the second carrier plate 2, and the sliding rod 31 is slidably matched with the sliding bearing 33;

[0056] As in the above structure, by arranging the sliding bearing 33 on the second carrier plate 2 and cooperating with the slide rod 31 , the stability of the relative movement between the first carrier plate 1 and the second carrier plate 2 can be ensured.

[0057] The sleeve 4 includes a limiting plate 41 and a cylinder 42, wherein the limiting plate 41 is abutted against the first carrier plate 1, and a positioning groove 401 is provided at the edge of the limiting plate 41; one end of the cylinder 42 is connected to the limiting plate 41, and the cylinder 42 passes through the first carrier plate 1;

[0058] As in the above structure, when assembling the sleeve 4, the sleeve 4 is inserted into the first carrier plate 1 through the cylinder body 42, and then the first carrier plate 1 is connected with bolts, and the limit plate 41 is pressed by the end of the bolt, so as to realize the assembly and fixation of the sleeve 4; specifically, during installation, the bolt passes through the positioning groove 401, so that the end of the bolt has a larger area to be pressed on the limit plate 41.

[0059] like Figure 2 and Figure 3 As shown, the first carrier plate 1 and the second carrier plate 2 are both frame-shaped structures, and a first connecting arm 11 is provided on the first carrier plate 1, and the first connecting arm 11 passes through the second carrier plate 2;

[0060] As in the above structure, by providing the first connecting arm 11, it can be used to connect the driving member to drive the tooling to move. In this case, the second carrier plate 2 is connected to a driving member alone to drive the ejector rod 5 to move, thereby pushing the nut 100 into the mold 200;

[0061] At the same time, since the first carrier plate 1 and the second carrier plate 2 are both frame structures, they have the advantages of simple structure and lightness, and are convenient for observing the positions of various components, further ensuring that the nut 100 can be accurately placed.

[0062] Furthermore, a second connecting arm 21 is disposed on the second carrier plate 2, and the second connecting arm 21 is aligned with the first connecting arm 11, and a gap is left between the second connecting arm 21 and the first connecting arm 11;

[0063] As in the above structure, the ejector rod can be assembled on the second connecting arm 21, and the sleeve 4 can be assembled on the first connecting arm 11 to achieve more nut assembly work;

[0064] In some embodiments, a linear displacement component such as a cylinder may be installed between the first connecting arm 11 and the second connecting arm 21 to adjust the distance between the first carrier plate 1 and the second carrier plate 2 .

[0065] like Figure 1 As shown, one end of the positioning rod 6 is connected to the second carrier plate 2, and the positioning rod 6 is parallel to the ejector rod 5;

[0066] As in the above structure, by providing a positioning rod 6, when the tooling is in operation, it can be plugged into the mold 200 to achieve a guiding and positioning function, ensuring that the sleeve 4 can cooperate with the limiting rod 400.

[0067] like Figure 3 As shown, the support rod 7 and the second carrier plate 2 are configured as an integrated structure, and one end of the ejector rod 5 is connected to the support rod 7;

[0068] As in the above structure, a support rod 7 is provided on the second carrier plate 2 for installing the ejector rod 5; specifically, the support rod 7 is located at the periphery of the second carrier plate 2, which facilitates the disassembly and assembly of the ejector rod 5 and the observation of its movement, thereby improving the convenience of application.

[0069] Specific implementation steps:

[0070] First, the nut 100 is placed in the sleeve 4, and then the tooling is moved as a whole to the top of the mold 200, and then moves toward the mold 200, and the sleeve 4 will drive the nut 100 to be sleeved on the limit rod 400. Due to the movement of the sleeve 4, when the nut 100 contacts the limit rod 400, it will move toward the inside of the sleeve 4;

[0071] Then the sleeve 4 will be pressed against the mold 200, and the second carrier plate 2 will drive the ejector rod 5 to continue to move, at this time compressing the elastic member 3, and the displacement of the ejector rod 5 will press the nut 100 into place, and the nut 100 will remain on the limit rod 400, and then the tooling will be separated from the mold 200;

[0072] Finally, injection molding is performed. After the injection molding is completed, the limiting rod 400 is separated from the mold 200 along the guide sleeve 300, and the nut 100 remains in the injection molded part.

[0073] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
