[0047] Further, in order to make the sliding plate 113 and the fixed plate 111 slip automatically reset, the positioning mechanism 11 further comprises two fixed seats 114 and elastic members 115, the two fixed seats 114 are arranged on both sides of the fixed plate 111, and the two fixed seats 114 are fixedly connected with both ends of the sliding plate 113; the elastic member 115 is arranged between one end of the fixed plate 111 and the fixed seat 114, and the sliding plate 113 moves along the first direction to drive the fixed seat 114 to move synchronously to compress or stretch the elastic member 115. The elastic member 115 is used to provide elastic force to the sliding plate 113 when the sliding plate 113 resets, and the two fixed seats 114 are used to limit the movement of the sliding plate 113 along the first direction to prevent the sliding plate 113 from being separated from the fixed plate 111. In the embodiment, the elastic member 115 is preferably a spring, and the two fixed seats 114 are respectively a left fixed seat 114 and a right fixed seat 114. The elastic member 115 is arranged on the left side of the fixed plate 111, i.e. between the left fixed seat 114 and the left end of the fixed plate 111; the right fixed seat 114 is in contact with the fixed plate 111 to limit the movement of the sliding plate 113 to the right side; specifically, one end of the elastic member 115 is installed in the left fixed seat 114 through the limiting hole arranged on the left fixed seat 114, and the other end of the elastic member 115 is installed on the fixed plate 111 through the limiting hole arranged on the left side of the fixed plate 111.

[0048] Please refer to Figure 2 and Figure 5The guiding mechanism 12 includes a mounting plate 121, a fixed table 122, a limiting support column 123, and a first handle 124. The mounting plate 121 is parallel to the sliding plate 113 and is fixedly connected to the sliding plate 113. The fixed table 122 and the limiting support column 123 are both provided in plurality. The fixed table 122 is fixedly arranged on the mounting plate 121 and is used for bearing and guiding the material piece. The limiting support column 123 is fixedly arranged on the end face of the mounting plate 121 facing the injection mold 2 and is used for making the mounting plate 121 parallel to the mold surface of the injection mold 2. The first handle 124 is arranged on the mounting plate 121 and is used for holding and conveniently controlling the mounting plate 121 to exert force on the mounting plate 121, so as to transmit power to the fixed table 122. In the embodiment, the fixed table 122 and the limiting support column 123 are both located on the end face of the mounting plate 121 facing the injection mold 2, that is, on the left side face of the mounting plate 121. The number of the fixed table 122 can be increased or decreased according to the number of different products, and is generally two to sixteen. The limiting support column 123 is provided in four to cooperatively ensure that the mounting plate 121 is parallel to the mold surface of the injection mold 2. The first handle 124 is located in the middle region of the end face of the mounting plate 121 away from the injection mold 2, that is, in the middle region of the right side face of the mounting plate 121. The fixed table 122 is arranged corresponding to the embedded hole 21, so as to facilitate the accurate embedding of the material piece arranged on the fixed table 122 into the embedded hole 21.

[0049] It can be understood that the positioning needle 112 is inserted into the device positioning hole 22, the end of the limiting support column 123 away from the mounting plate 121 is pressed against the mold surface of the injection mold 2, so that the mounting plate 121 is parallel to the mold surface of the injection mold 2, so as to keep the fixed table 122 perpendicular to the mold surface of the injection mold 2 and align with the embedded hole 21. By holding the first handle 124, force is exerted on the mounting plate 121 to move in the first direction, the mounting plate 121 drives the sliding plate 113 to move synchronously, so that the guiding mechanism 12 moves to the right as a whole, so that the guiding mechanism 12 can be positionally adjusted relative to the positioning mechanism 11, so that the guiding mechanism 12 is switched from the guiding position to the giving position. At this time, the fixed table 122 also moves to the right, aiming to be dislocated from the embedded hole 21, so as to release the limiting of the material piece by the fixed table 122.

[0050] Please refer to Figure 6 and Figure 7 The fixed table 122 is made of stainless steel and is processed by CNC precision machining process, which effectively prevents scratching of the product and improves the installation accuracy of the material piece, thereby improving the overall quality of the product. Specifically, the fixed table 122 is provided with a positioning groove 1221, and the positioning groove 1221 is provided with a first side face 1222 and a second side face 1223 along a second direction, as shown in Figure 6As shown. The component has an initial state, a pre-embedded state, and a fully embedded state. In the initial state, the component is located within the positioning groove 1221, and the first side surface 1222 is in contact with the component, as shown. Figure 7 As shown; when the part is pre-embedded, the second side 1223 contacts and presses against the part, and the end of the part near the injection mold 2 is located inside the injection mold 2; when the part is fully embedded, the part is detached from the positioning groove 1221, and the part is completely located inside the injection mold 2. In this embodiment, the positioning groove 1221 consists of an upper groove, a middle groove, and a lower groove. The upper groove is used to accommodate and position the upper end of the part, the middle groove is used to accommodate and position the undercut structure of the part, and the lower groove is used to accommodate and position the lower end of the part. By setting the positioning groove 1221 on the fixed platform 122, the positioning groove 1221 is adapted to the part, which can effectively fix the part. The positioning groove 1221, through the cooperation of the first side 1222 and the second side 1223, provides a correction effect for the dimensional accuracy of the part during the pushing process, preventing the part from shaking due to excessive distance during the embedding process, thereby improving the embedding accuracy and increasing production efficiency.

[0051] Understandably, when the guide mechanism 12 is in the guide position, the part is installed in the positioning groove 1221 of the fixed platform 122 and contacts the first side 1222. The part is precisely positioned by aligning with the injection mold 2 through the positioning mechanism 11. The push mechanism 13 pushes the part in the positioning groove 1221 from the initial state to the pre-embedded state along the second direction. At this time, the part contacts and presses against the second side 1223, and the end of the part near the injection mold 2 is located in the injection mold 2 to complete the pre-embedding. The guide mechanism 12 relative to the positioning mechanism 11 performs... Position adjustment involves applying force to the mounting plate 121, causing it to slide relative to the positioning mechanism 11 along the first direction. This allows the mounting plate 121 to move synchronously with the fixed platform 122, disengaging the part from the opening of the positioning groove 1221. This releases the second side 1223 from its restriction on the part, at which point the guide mechanism 12 switches to the yielding position. Subsequently, the pushing mechanism 13 pushes the part a second time, changing it from a pre-embedded state to a fully embedded state. At this point, the part is fully embedded in the injection mold 2, completing the embedding of the part.

[0052] Please see Figure 2 and Figure 8The pushing mechanism 13 is located on the side of the mounting plate 121 away from the positioning mechanism 11, the pushing mechanism 13 comprises a bearing plate 131, a thimble assembly 132, a reset assembly 133 and a second handle 134, the bearing plate 131 is parallel to the mounting plate 121 and is located on the side of the mounting plate 121 away from the sliding plate 113, the thimble assembly 132 and the reset assembly 133 are arranged on the bearing plate 131, the bearing plate 131 moves towards the injection mold 2 to drive the thimble assembly 132 to push the material piece in the second direction, the reset assembly 133 is used for resetting the bearing plate 131 to move the bearing plate 131 away from the injection mold 2, the second handle 134 is fixedly arranged on the end face of the bearing plate 131 away from the mounting plate 121, and is used for conveniently outputting power to the bearing plate 131, and then transmitting the power to the thimble assembly 132. In the embodiment, the thimble assembly 132 is provided in multiple groups, the number of the thimble assembly 132 is the same as that of the fixed table 122, and the thimble assembly 132 is arranged in position with the fixed table 122; the reset assembly 133 is provided in multiple groups, and the multiple reset assemblies 133 are matched to provide greater reset force; the first handle 124 and the second handle 134 have a movement gap, the movement gap is used for providing space for the first handle 124 and the second handle 134, and facilitating operation of the first handle 124 and the second handle 134; the mounting plate 121 and the bearing plate 131 are provided with weight reduction holes, the weight reduction holes are used for reducing the overall weight of the guiding mechanism 12 and the pushing mechanism 13, thereby reducing the overall weight of the embedding device 1 and reducing the excessive physical exertion of personnel.

[0053] Please refer to Figure 8 The thimble assembly 132 comprises a thimble 1321 arranged in the second direction and a mounting seat 1322, the mounting seat 1322 is fixedly arranged on the bearing plate 131, one end of the thimble 1321 is fixedly connected with the mounting seat 1322, and the other end of the thimble 1321 is aligned with the material piece. When a leftward force is applied to the bearing plate 131 in the second direction, the bearing plate 131 drives the thimble 1321 to move leftward, the thimble 1321 slides along the positioning groove 1221 to drive the material piece to move, so that the material piece contacts and abuts against the second side surface 1223, and at this time, the material piece is switched from the initial state to the embedded state.

[0055] The reset assembly 133 comprises a mounting column 1331 and a reset piece 1332. The mounting column 1331 is fixedly arranged on the bearing plate 131. The reset piece 1332 is preferably a spring. The reset piece 1332 is sleeved on the outer peripheral wall of the mounting column 1331 and is located between the bearing plate 131 and the mounting plate 121. The mounting plate 121 is provided with a relief hole 1211. The end of the mounting column 1331 away from the bearing plate 131 penetrates through the relief hole 1211, and the mounting column 1331 is in sliding connection with the mounting plate 121 along the second direction. In this embodiment, the relief hole 1211 is a waist-shaped hole. The relief hole 1211 provides a relief space for the movement of the mounting plate 121 along the first direction. When the mounting plate 121 moves along the first direction, the mounting column 1331 moves in the relief hole 1211. The bearing plate 131 does not resist the mounting column 1331, so that the movements of the mounting plate 121 and the bearing plate 131 can be independent of each other.
