The lower mold is provided with a second contouring component. When the upper mold and the lower mold abut against each other, the molding module moves closer to the first contouring component, and the first contouring component and the second contouring component abut against each other, so that the first contouring component, the molding module and the second contouring component together define a cavity. An injection assembly is disposed within the upper mold and communicates with the cavity to inject molten plastic into the cavity to obtain the molded connector housing.

[0014] The above-described solution of this utility model has at least the following beneficial effects: The injection mold provided by this utility model can first drive the upper mold and lower mold to approach each other, so that the molding module can enter the upper mold and approach the first contouring part when the upper mold and lower mold approach each other. At the same time, when the upper mold and lower mold approach each other, the first contouring part and the second contouring part abut against each other, so that the first contouring part, the molding module and the second contouring part can define the cavity.

[0024] The injection mold of this utility model embodiment is described in detail below with reference to the accompanying drawings.

[0025] like Figures 1 to 3 As shown, the injection mold provided in this embodiment of the present invention is used to injection mold the connector housing 50. Figure 1 As shown, the connector housing 50 has a claw portion 51 and an internal thread 52 at both ends, and an external thread 53 between the claw portion 51 and the internal thread 52. The injection mold includes an upper mold 10, a lower mold 20, an injection assembly 30, and a drive assembly 40. The upper mold 10 is provided with a first contouring part 11 and molding modules 12 located on both sides of the first contouring part 11. The molding modules 12 and the first contouring part 11 can move closer to or further away from each other. The first contouring part 11 is used to mold the claw portion 51 of the connector housing 50, and the molding modules 12 are used to mold the external thread 53 of the connector housing 50. The lower mold 20 is connected to the upper mold 10 and can move closer to or further away from each other when driven. The lower mold 20 is provided with a second contouring part 21, which is used to mold the internal thread 53 of the connector housing 50. 52; The lower mold 20 can be fixed on the injection molding equipment, and the upper mold 10 can be driven by a cylinder or other means so that the upper mold 10 and the lower mold 20 can move closer or further apart when driven; when the upper mold 10 and the lower mold 20 abut against each other, the molding module 12 approaches the first profile 11, and the first profile 11 and the second profile 21 abut against each other so that the first profile 11, the molding module 12 and the second profile 21 together define a cavity 101; the injection component 30 is disposed in the upper mold 10 and communicates with the cavity 101 to inject molten plastic into the cavity 101 to obtain the molded connector housing 50; the drive component 40 is disposed on the side of the lower mold 20 and is connected to the second profile 21 for driving the second profile 21 to rotate and disengage from the connector housing 50.

[0026] like Figure 1 , Figure 4 , Figure 5 and Figure 10As shown, the molding module 12 includes: a molding block 121, a connecting plate 122, and a transmission plate 123. The molding block 121 is slidably disposed within the upper mold 10 in the horizontal direction; the first end of the connecting plate 122 is connected to the molding block 121, and the second end of the connecting plate 122 is provided with an insertion hole 1221; one end of the transmission plate 123 is fixed to the lower mold 20, and the other end is inserted into the insertion hole 1221 and slidable within the insertion hole 1221; Figure 10 As shown, the transmission plate 123 includes a straight segment 1231 and an inclined segment 1232. The straight segment 1231 is located on the connecting plate 122. The inclined segment 1232 is connected to the straight segment 1231 and is located at the bottom of the connecting plate 122.

[0027] In this embodiment, the molding module 12 has two sets, located on both sides of the upper mold 10 in the width direction. When the upper mold 10 and the lower mold 20 approach each other, the connecting plate 122 and the transmission plate 123 approach each other, causing the transmission plate 123 to slide in the insertion hole 1221 and enter the insertion hole 1221 from the inclined section 1232 to the straight section 1231. When the straight section 1231 enters the insertion hole 1221, the straight section 1231 pushes the molding block 121 to slide into the upper mold 10, so that the splicing thread grooves 1211 of the two molding blocks 121 can be spliced ​​together. After splicing, the splicing thread groove 1211 can surround the second profile 21, and a gap is formed between it and the second profile 21 when it is close to the second profile 21. This gap is the lower end of the cavity 101. Thus, after injecting molten plastic, the splicing thread groove 1211 can be injection molded into the external thread 53 of the connector housing 50. After injection molding is completed, the upper mold 10 and the lower mold 20 are driven to separate from each other, so that the connecting plate 122 and the transmission plate 123 move away from each other. The transmission plate 123 slides in the insertion hole 1221 and enters the insertion hole 1221 from the straight section 1231 to the inclined section 1232. Since there is an inclined surface 1222 on the inner side of the insertion hole 1221, and the inclined section 1232 is inclined towards the inclined surface 1222, the inclined section 1232 can push against the inclined surface 1222 in the insertion hole 1221 when it slides in the insertion hole 1221. This drives the connecting plate 122 to move horizontally and pulls the molding block 121 out of the upper mold 10, so that the molding block 121 moves away from the second profile 21. This completes the demolding of the external thread 53 of the connector housing 50. It can be understood that by driving the molding block 121 to move synchronously by the upper mold 10 and the lower mold 20, the injection molding and demolding actions are reduced and the efficiency is higher.

[0028] like Figure 6As shown, the inner peripheral wall of the first profile 11 has a plurality of protrusions 111, which are spaced apart around the central axis of the first profile 11. The first profile 11 has a molding post 112 inside, which extends along the axial direction of the first profile 11 and is spaced apart from the plurality of protrusions 111. The plurality of protrusions 111 and the molding post 112 form the upper end of the cavity 101, so that the claw portion 51 of the connector housing 50 can be injection molded by the plurality of protrusions 111 and the molding post 112.

[0029] like Figure 9 As shown, the second contouring part 21 includes a rotating part 211 and a forming part 212. The rotating part 211 is rotatably disposed inside the lower mold 20 and is coaxially arranged with the first contouring part 11. The forming part 212 is disposed on the rotating part 211 and has a positioning hole 214 at its top. When the upper mold 10 and the lower mold 20 are close together, the first contouring part 11 can abut against the second contouring part 21. At the same time, it can be inserted and positioned with the positioning post 1121 of the forming post 112 through the positioning hole 214. When the forming blocks 121 are close together, the splicing thread groove 1211 splices to form the lower end of the cavity 101. At the same time, the forming part 212 of the second contouring part 21 can extend into the splicing thread groove 1211, so that the forming thread 213 provided on the outer peripheral surface of the forming part 212 is located at the lower end of the splicing thread groove 1211. Understandably, after the upper mold 10 and the lower mold 20 approach each other, the first contouring part 11 and the second contouring part 21 can abut against each other and the molding block 121 can approach each other, so that multiple protrusions 111 and molding pillars 112 form the upper end of the cavity 101, and the splicing thread groove 1211 and the molding part 212 form the lower end of the cavity 101. In this way, multiple protrusions 111 and molding pillars 112 can be used to injection mold the claw part 51 of the connector housing 50, the splicing thread groove 1211 can be used to injection mold the external thread 53 of the connector housing 50, and the molding thread 213 on the molding part 212 can be used to injection mold the internal thread 52 of the connector housing 50. During the injection molding process, the cavity 101 can be quickly formed by simply driving the upper mold 10 and the lower mold 20 to approach each other, making the injection molding efficiency faster.

[0030] like Figure 2 , Figure 7 and Figure 8As shown, the injection assembly 30 includes a main pipe 31 and a branch pipe 32. The main pipe 31 is disposed through the upper mold 10 along its height direction. The branch pipe 32 is connected to the main pipe 31 and extends through the first contouring member 11 to connect to the cavity 101. Furthermore, the branch pipe 32 has an annular branch 321, which surrounds the outer periphery of the first contouring member 11. The inner circumferential surface of the annular branch 321 has an injection portion 322 extending into the cavity 101. The injection portion 322 is tightly fitted with the first contouring member 11, resulting in better sealing between the injection portion 322 and the first contouring member 11.

[0031] In a specific embodiment of this application, during the injection molding process of the connector housing 50, the upper mold 10 and the lower mold 20 are first driven to move closer to each other, causing the first contouring part 11 and the second contouring part 21 to abut against each other. Simultaneously, the transmission plate 123 slides within the insertion hole 1221 and enters the insertion hole 1221 from the inclined section 1232 to the straight section 1231. When the straight section 1231 enters the insertion hole 1221, it pushes the molding block 121 to slide into the upper mold 10, causing the molding blocks 121 to abut against each other and be located on the outer periphery of the second contouring part 21. This allows the multiple protrusions 111 of the first contouring part 11 and the molding post 112 to form a... The upper end of the molding cavity 101 is joined by the threaded groove 1211 and the molding part 212 to form the lower end of the cavity 101. After the cavity 101 is formed, molten plastic can be injected from the main pipe 31 through equipment such as a screw press. The molten plastic can then enter the branch pipe 32 from the main pipe 31, and then enter the annular branch 321 through the branch pipe 32. Finally, it is injected into the cavity 101 from the injection part 322, so that the connector housing 50 is injection molded and cooled in the cavity 101. This completes the injection molding operation of the connector housing 50. Various irregular shapes of the connector housing 50 can be molded in one step, and the entire injection mold can be driven synchronously, resulting in higher injection efficiency. like Figure 10 and 11 As shown, the drive assembly 40 includes: a support plate 41, a motor 42, a drive gear 43, a driven gear 44, and a gear set 45. The support plate 41 is disposed on the side of the lower mold 20; the motor 42 is fixed on the support plate 41; the drive gear 43 is disposed on the motor shaft of the motor 42; the driven gear 44 and the drive gear 43 are connected by a transmission chain; the gear set 45 is rotatably disposed in the lower mold 20 and is connected to the driven gear 44 for synchronous rotation with the driven gear 44; furthermore, the gear set 45 includes: an intermediate gear 451 and a demolding gear 452. The intermediate gear 451 is disposed on the driven gear 44 and rotates synchronously with the driven gear 44; the demolding gear 452 meshes with the intermediate gear 451, and the second contouring member 21 can be coaxially disposed on the demolding gear 452 and can rotate synchronously with the demolding gear 452.

[0032] In this embodiment, after the injection molding operation of the connector housing 50 is completed, the connector housing 50 needs to be demolded. During the demolding process, the motor 42 can first drive the drive gear 43 to rotate, so that the drive gear 43 can drive the driven gear 44 to rotate through the transmission chain. When the driven gear 44 rotates, the intermediate gear 451 can rotate synchronously with the driven gear 44. Since the demolding gear 452 meshes with the intermediate gear 451, the intermediate gear 451 can drive the demolding gear 452 to rotate, thereby demolding the connector housing 50. The mold gear 452 synchronously drives the second contouring part 21 to rotate, allowing the forming thread 213 on the second contouring part 21 to loosen from the internal thread 52 of the connector housing 50. This allows the second contouring part 21 to first be demolded from the connector housing 50. Then, by driving the upper mold 10 and lower mold 20 away from each other, the first contouring part 11 and the second contouring part 21 move away from each other, while the jaw portion 51 of the connector housing 50 is demolded. When the upper mold 10 and lower mold 20 move away from each other, they can simultaneously allow the connector housing 50 to be demolded. The connecting plate 122 and the transmission plate 123 are moved away from each other. The transmission plate 123 slides within the insertion hole 1221, causing the inclined section 1232 to enter the insertion hole 1221. Since the inner side of the insertion hole 1221 has an inclined surface 1222, and the inclined section 1232 is inclined towards the inclined surface 1222, the inclined section 1232 can push against the inclined surface 1222 within the insertion hole 1221 when sliding within it. This causes the connecting plate 122 to move horizontally and simultaneously pulls the forming block 121 out of the upper mold 10, causing the forming block 121 to... Moving away from the second profile 21, the demolding of the external thread 53 of the connector housing 50 is completed, resulting in better overall demolding operation linkage and higher efficiency. Preferably, after the molding thread 213 of the second profile 21 is demolded, the motor 42 can drive the drive gear 43 to rotate in the opposite direction again, so that the drive gear 43 drives the intermediate gear 451 to rotate in the opposite direction, and the intermediate gear 451 can drive the demolding gear 452 to rotate in the opposite direction, so that the second profile is reset with the rotation of the demolding gear 452, so as to facilitate the injection molding operation of the next connector housing 50.

[0033] The injection mold provided by this utility model can first drive the upper mold 10 and the lower mold 20 to move closer to each other, so that the molding module 12 can enter the upper mold 10 and approach the first contouring part 11 when the upper mold 10 and the lower mold 20 approach each other. At the same time, when the upper mold 10 and the lower mold 20 approach each other, the first contouring part 11 and the second contouring part 21 abut against each other, so that the first contouring part 11, the molding module 12 and the second contouring part 21 can define the cavity 101. Then, molten plastic can be injected into the cavity 101 through the injection component 30 by means of screw injection or other methods. After the molten plastic cools, the desired product is obtained. When demolding the connector housing 50, the second contouring part 21 is driven to rotate by the drive assembly 40, so that the threads between the second contouring part 21 and the connector housing 50 are separated. Then, the upper mold 10 and the lower mold 20 are driven to move away from each other, so that the molding module 12 moves away from the first contouring part 11, and the first contouring part 11 and the second contouring part 21 can also move away from each other. This completes the demolding of the connector housing 50, avoids damage to the connector housing 50 during the demolding process, improves production quality, and can quickly demold to improve production efficiency.
