[0028] Reference Figures 1 to 4As shown, an embodiment of the utility model provides an injection mold for realizing metal rod positioning, comprising a lower mold assembly 1 and an upper mold assembly 2 arranged relatively to each other, the lower mold assembly 1 is provided with a positioning structure for inserting a metal rod 5, the upper mold assembly 2 and the lower mold assembly 1 are molded together to form a molding cavity for accommodating injected plastic material, one end of the metal rod 5 is arranged on the positioning structure, and the other end is partially accommodated in the molding cavity, the metal rod 5 is provided with a positioning groove 51, the upper mold assembly 2 is matched with the positioning groove 51 and provided with a positioning portion 4, the upper mold assembly 2 is also provided with a driving member, the driving member drives the positioning portion 4 to cooperate with the positioning groove 51, so that the position of the metal rod 5 relative to the molding cavity is fixed, and during the injection molding process, even under the impact of the injection molding material, the metal rod 5 can remain fixed, and the metal rod 5 does not deflect or shift. In the embodiment of the utility model, a positioning structure for inserting the metal rod 5 is provided on the lower mold assembly 1, and a positioning portion 4 matching the positioning groove 51 on the metal rod 5 is provided on the upper mold assembly 2. The metal rod 5 is fixed in the radial and axial directions before injection molding, so that one end of the metal rod 5 is inserted in the positioning structure and the other end is partially accommodated in the molding cavity. After fixation, the plastic material can be injected; the positioning portion 4 provided on the upper mold assembly 2 cooperates with the positioning groove 51 provided on the metal rod 5 to position the metal rod 5, further ensuring that the metal rod 5 will not shake or rotate during the injection molding process; after the metal rod 5 is fixed, the injection molding part 12 can be formed by injection molding, and the metal rod 5 and the injection molding part 12 can be combined at the same time, so that the required product can be molded at one time, and the metal rod 5 and the injection molding part 12 have high matching accuracy, high product yield and good quality.

[0029] refer to Figure 4 and Figure 5 As shown, the positioning groove 51 provided on the metal rod 5 is a strip-shaped positioning hole or a round hole opened along the length direction of the metal rod 5. When the positioning groove 51 is set as a strip-shaped positioning hole, the positioning portion 4 matches the positioning groove 51 and is set as a plate. When the positioning groove 51 is set as a round hole, the positioning portion 4 matches the positioning groove 51 and is set as a rod. The positioning portion 4 can be inserted or penetrated in the positioning groove 51. In this embodiment, the positioning groove 51 of the metal rod 5 is set as a strip-shaped positioning hole, and the corresponding positioning portion 4 is set as a plate-shaped positioning portion 4, and the positioning portion 4 penetrates the positioning groove 51. The cooperation between the positioning portion 4 and the positioning groove 51, on the one hand, ensures that the position of the metal rod 5 relative to the molding cavity meets the requirements after being inserted and set in the positioning structure. On the other hand, since the metal rod 5 has a certain length, the clamping force generated when the mold is clamped or the injection force generated during the injection molding process may cause the metal rod 5 to shake. Therefore, the cooperation between the positioning portion 4 and the positioning groove 51 can prevent the metal rod 5 from shaking or rotating when the mold is clamped and during the injection molding process to a certain extent.

[0030] In specific applications, the driving member can be set to a cylinder 11, a pneumatic cylinder or other linear driving mechanism. In this embodiment, it is set to a cylinder 11. A fixed seat 3 is also provided between the cylinder 11 and the positioning part 4. The fixed seat 3 is used to fix the positioning part 4 and receive the thrust transmitted by the cylinder 11, so as to control the coordination between the positioning part 4 and the positioning groove 51.

[0031] refer to Figure 2 and Figure 3 As shown, the injection mold can be reasonably planned and laid out according to the actual injection molded product. In this embodiment, the mold can complete the injection molding of four products at one time. The positioning structure arranged in the lower mold assembly 1 includes a support member 10 and a sliding assembly. The support member 10 is used to support the metal rod 5 to ensure that the position of the metal rod 5 along the axial direction is fixed relative to the position of the molding cavity. One end of the support member 10 is fixedly arranged on the sliding assembly, and the other end is fixed to the metal rod 5; the sliding assembly includes a base 7 fixed to the lower mold assembly 1. In this embodiment, the base 7 is set to a rectangular parallelepiped shape. Along the long side direction of the base 7, the base 7 is provided with a sliding groove. The sliding block 8 is slidably arranged in the sliding groove. A T-shaped receiving groove 81 is arranged on one end face of the sliding block 8. The receiving groove 81 is arranged in an inclined state. The other end face of the sliding block 8 is provided with an internal threaded hole 82; the sliding assembly is matched with the receiving groove 81 and is provided with a T-shaped slider 9. One end of the T-shaped slider 9 is slidably arranged in the receiving groove 81, and the other end is fixed to the support member 10 through the through hole 92 through the pin 101. Since the accommodating groove 81 is set in an inclined state, the T-shaped slider 9 is provided with an inclined surface 91 corresponding to the accommodating groove 81, so the cooperation between the inclined surfaces can make the T-shaped slider 9 move up and down relative to the base 7. Since the base 7 is fixed to the lower mold assembly 1, it can be further inferred that during the sliding process of the sliding block 8, the T-shaped slider 9 moves up and down relative to the lower mold assembly 1, thereby driving the support member 10 to move up and down relative to the lower mold assembly 1, so that the position of the metal rod 5 relative to the molding cavity can be adjusted. The advantage of such a setting is that on the one hand, the metal rod 5 can be limited, and on the other hand, the position of the metal rod 5 of different lengths relative to the molding cavity can be adapted, so that the same mold can be used to inject products of different lengths of metal rods 5.

[0032] Preferably, the sliding block 8 is provided with an internal threaded hole 82 along the sliding direction, the screw 71 provided on the base 7 is adapted to the internal threaded hole 82, the screw 71 is meshed with the internal thread in the internal threaded hole 82, and rotating the screw 71 can drive the sliding block 8 to slide in the sliding groove. The base 7 is also provided with a display block 73 for indicating the path of the screw 71. A display window 72 for accommodating the display block 73 is provided on the upper surface of the base 7. As the screw 71 rotates, the display block 73 moves linearly relative to the long side direction of the base 7. The stroke position of the display block 73 can be observed through the display window 72. The display block 73 is set in a rectangular shape, and the center position along the thickness direction matches the threaded hole set on the screw 71. The thickness of the display block 73 is 1 / 3 of the length of the display window 72. The advantages of setting the display block 73 and the display window 72 are: it can intuitively reflect the direction in which the screw 71 can be rotated, and further reflect the position relationship of the metal rod 5 relative to the molding cavity by controlling the screw 71. It is defined that one end of the base 7 where the screw 71 is set is a first direction, and the end away from the screw 71 is a second direction, that is, when the screw 71 rotates counterclockwise, the display block 73 moves linearly in the display window 72 along the second direction. At this time, the sliding block 8 moves in the sliding groove along the first direction, the T-shaped slider 9 moves downward along the inclined surface in the receiving groove 81, driving the support member 10 to move downward relative to the lower mold assembly 1, so that the metal rod 5 moves downward relative to the position of the molding cavity. When the display block 73 moves to abut the edge of the display window 72 in the first direction, the length of the metal rod 5 supported by the support member 10 is the longest metal length that this mold can adapt to. On the contrary, when the screw 71 rotates clockwise, the display block 73 moves linearly in the display window 72 along the first direction. At this time, the sliding block 8 moves in the sliding groove along the second direction, and the T-shaped slider 9 moves upward along the inclined surface in the receiving groove 81, driving the support member 10 to move upward relative to the lower mold assembly 1, so that the metal rod 5 moves upward relative to the position of the molding cavity. When the display block 73 moves to abut the edge of the display window 72 in the second direction, the length of the metal rod 5 supported by the support member 10 is the shortest metal length that this mold can adapt to. Therefore, the setting of the display window 72 and the display block 73 can reflect the rotation direction of the screw 71 on the one hand, and on the other hand, it can be judged by the position of the display block 73 that, according to the length of the target metal rod 5 adjusted to the position relative to the molding cavity, the display block 73 should move in the first direction or the second direction, thereby determining the moving direction of the metal rod 5.

[0033] In this embodiment, the support member 10 is set as a rod-shaped structure, one end of the support member 10 is supported on the metal rod 5, and the other end is fixed to the T-shaped slider 9. When the screw rod 71 is engaged with the internal threaded hole 82 to drive the sliding block 8 to slide, so that the T-shaped slider 9 moves up and down relative to the lower mold assembly 1, the support member 10 is synchronously driven to move up and down relative to the lower mold assembly 1, and the metal rod 5 is further driven by the support member 10 to move up and down relative to the position of the molding cavity. The specific moving process is as follows: the base 7 is fixed to the lower mold assembly 1 and remains stationary, the screw rod 71 is engaged with the internal threaded hole 82, and can drive the sliding block 8 to move. The setting of the inclined surface enables the T-shaped slider 9 to move up and down relative to the lower mold assembly 1, and further drives the support member 10 to move up and down relative to the lower mold assembly 1. During the entire action process, the base 7 remains stationary, the sliding block 8 moves in the horizontal direction, and the T-shaped slider 9 moves in the vertical direction. Such a setting can achieve relative height adjustment, so that the metal rod 5 reaches a suitable position, and achieve the effect of producing a plurality of models of products with different sizes of metal rods 5 by one mold. After molding, the product can be demoulded by moving the support member 10 toward the upper mold assembly.

[0034] A sleeve is also arranged outside the metal rod 5, and the sleeve is sleeved on the metal rod 5, and a positioning groove 51 avoidance groove is opened at the position corresponding to the positioning groove 51. The arrangement of the sleeve can improve the fixing effect of the metal rod 5 and make the metal rod 5 clean after injection molding.

[0035] In order to further ensure the position of the metal rod 5 relative to the molding cavity, the upper mold assembly 2 is also provided with an optical fiber system for detecting whether the metal rod 5 is properly placed. The optical fiber system is connected to the mold programming system, and the optical fiber system includes a sensing seat 6 and a channel 61. The sensing seat 6 is arranged on the corresponding outer side surface of the upper mold assembly 2. The channels 61 are arranged in two numbers, and the metal rod 5 is inserted into the positioning structure and placed between the two channels 61. The channel 61 passes through the upper mold assembly 2 and is connected to the sensing seat 6 arranged on the corresponding two outer sides. Due to the setting of the optical fiber system, after the metal rod 5 is manually installed, the optical fiber system starts to work. If the optical fiber system cannot sense the metal rod 5, it means that the metal rod 5 is not properly placed, and the mold cannot be closed. The metal rod 5 needs to be manually adjusted until the optical fiber system senses the metal rod 5, and the mold can be closed and injection molding can begin.

[0036] Reference Figure 5-6In the embodiment of the utility model, the metal rod 5 is set as a cylinder, and the two ends can be provided with groove structure features according to the actual application of the product. The groove feature is set at one end of the molding cavity to increase the force between the metal rod 5 and the plastic molded part after injection molding, and the other end can be set as a groove or other features according to the actual use requirements of the product. The advantage of setting both ends as grooves is that when installing and fixing the metal rod 5, there is no need to consider the direction of the metal rod 5. In this embodiment, the metal rod 5 is provided with a positioning groove 51, and the design of the positioning groove 51 can be a functional structure of the product itself, or a structure specially designed for positioning under the premise of ensuring the function of the product; the injection molded part 12 can be a special-shaped gear structure, including a main body 121, teeth 122 extending along a part of the main body 121, and a protrusion 123 arranged along the thickness direction of the main body 121; the molding cavity for accommodating the injected plastic material is designed according to the actual product.

[0037] The present invention provides an injection mold for realizing metal rod positioning. Before injection molding, one end of the metal rod 5 is inserted into the positioning structure (positioning hole), and the other end is partially accommodated in the molding cavity. The positioning portion 4 is driven forward by the driving member to cooperate with the positioning groove 51 of the metal rod 5. After the metal rod 5 is fixed, the plastic material can be injected. In this way, the positioning portion 4 set on the upper mold assembly 2 cooperates with the positioning groove 51 set on the metal rod 5, so that the metal rod 5 can be fixed, ensuring that the metal rod 5 will not shake during the injection molding process. After the injection molding is completed, before the workpiece is demolded, the driving member drives the positioning portion 4 to withdraw backward The positioning groove 51 allows the metal rod 5 to be detached from the lower mold assembly 1; the design of the positioning structure can adapt to metal rods 5 of various lengths, so as to achieve the effect of one mold injecting multiple product models of metal rods 5 of different lengths; after the metal rod 5 is fixed, the injection molding part 12 can be formed by injection molding, and the metal rod 5 and the injection molding part 12 can be combined at the same time, and the required product can be molded in one time, and the operation is simple. The molded product does not need to perform other operations to realize the combination of the metal rod 5 and the injection molding part 12. The metal rod 5 and the injection molding part 12 have high matching accuracy, and the product yield rate is high and the quality is good.
