[0005] In order to produce a specific sensor connector, the present application provides a mold for producing automotive sensor connectors.

[0006] The mold for producing automotive sensor connectors provided by the present application adopts the following technical solutions:

[0007] A mold for producing automotive sensor connectors, comprising a fixed mold, a movable mold, a first core-pulling assembly, a second core-pulling assembly, and a demolding mechanism. The first core-pulling assembly and the second core-pulling assembly are oppositely arranged and located between the movable mold and the fixed mold. The first core-pulling assembly and the second core-pulling assembly respectively form a first connection hole and a second connection hole. The movable mold includes a substrate, a movable template mounted on the substrate, and a movable mold core mounted on the movable template. The fixed mold includes a fixed template and a fixed mold core mounted on the fixed template. The fixed mold is provided with an injection port for cooperating with an injection molding machine to inject molten material into. The first core-pulling assembly includes a first core-pulling block, and the second core-pulling assembly includes a second core-pulling block. The fixed mold core, the movable mold core, the first core-pulling block, and the second core-pulling block cooperate to form a cavity. The demolding mechanism is mounted on the substrate and includes a forming ejector block. The forming ejector block is slidably mounted on the movable template. One end of the forming ejector block is located in the cavity to form a structure groove. The opposite end faces of the first core-pulling block and the second core-pulling block are provided with insertion holes for inserting sensing terminals. The second core-pulling block forms a second connection hole, a semicircular structure notch, and an elastic clamping notch.

[0008] By adopting the above technical solutions, the first connection hole and the second connection hole are formed by the first core-pulling assembly and the second core-pulling assembly. After the movable mold and the fixed mold are separated from each other, the first core-pulling block and the second core-pulling block complete the demolding process through the core-pulling movement, smoothly completing the overall molding of the sensor connector without affecting the separation process of the movable mold and the fixed mold. The setting of the forming ejector block, in cooperation with the forming process of the structure groove, and at the same time, the forming ejector block also completes the demolding process after the sensor connector is molded through movement. A single structure realizes multiple functions. At the same time, the existence of the first core-pulling block and the second core-pulling block is also used for the placement of sensing terminals during the molding of the sensor connector, realizing the composite molding of the sensing terminals and the plastic part of the sensor connector. The overall setting of the movable mold and the fixed mold, that is, the semicircular structure notch corresponds to the movable mold, and the elastic clamping notch corresponds to the fixed mold, while determining the molding, does not affect the final demolding process.

[0009] Optionally, the first core-pulling block includes a first core-pulling base block and a first core-pulling replacement block. One end of the first core-pulling replacement block is detachably connected to the first core-pulling base block, and the other end of the first core-pulling replacement block forms a first connection hole. The second core-pulling block includes a second core-pulling base block and a second core-pulling replacement block. One end of the second core-pulling replacement block is detachably connected to the second core-pulling base block, and the other end of the second core-pulling replacement block forms a second connection hole.

[0010] By adopting the above technical solutions, the first core-pulling block is composed of a first core-pulling base block and a first core-pulling replacement block. Among them, the first core-pulling replacement block is used as the molding part. If dimensional errors occur after long-term use, or if the dimensions need to be adjusted, it is more convenient to replace and maintain by replacing the first core-pulling replacement block. The structure of the second core-pulling block is the same.

[0011] Optionally, a first positioning block is provided on the protruding portion of the first core-pulling block, a second positioning block is provided on the protruding portion of the second core-pulling block, and the fixed mold is provided with positioning holes for the insertion of the first positioning block and the second positioning block.

[0012] By adopting the above technical solution, through the first positioning block, when the fixed mold and the moving mold are in the closed mold state, the position accuracy of the first core-pulling block and the second core-pulling block is higher, playing a role in positioning and matching between the fixed mold and the first core-pulling block and the second core-pulling block.

[0013] Optionally, the fixed mold is provided with a guiding cavity for the entry of the first core-pulling block and the second core-pulling block. The opposite side walls of the first core-pulling block and the second core-pulling block are provided with inclined guiding surfaces. The cavity wall of the guiding cavity is in fitting contact with the guiding surfaces and pushes the first core-pulling block and the second core-pulling block into the molding state.

[0014] By adopting the above technical solution, even if the positions of the first core-pulling block and the second core-pulling block do not accurately reach the specified positions, when the fixed mold and the moving mold are closed, the cavity wall of the guiding cavity can push the guiding surfaces to make the first core-pulling block and the second core-pulling block in the specified accurate positions, ensuring the accuracy and quality of injection molding.

[0015] Optionally, the guiding surface is provided with an embedding groove, and a guiding block is installed in the embedding groove.

[0016] By adopting the above technical solution, the directly contactable detachable and replaceable guiding block can be made of a more wear-resistant material, and at the same time, the replacement of the guiding block is more convenient.

[0017] Optionally, the guiding block protrudes from the guiding surface and directly abuts against the cavity wall of the guiding cavity.

[0018] By adopting the above technical solution, the direct contact of the guiding block is ensured, and the direct contact between other parts of the first core-pulling block and the fixed mold is reduced.

[0019] Optionally, a locking plate is also provided. One end of the locking plate is fixed to the moving mold by screws, and the other end is fixed to the fixed mold by screws. There are two locking plates. The two locking plates respectively correspond to the positions of the first core-pulling assembly and the second core-pulling assembly, and the two locking plates are arranged on both sides of the connection line of the first core-pulling assembly and the second core-pulling assembly.

[0020] By adopting the above technical solution, through the locking plate, when the mold is not running or during handling and transportation, the relative static state between the fixed mold and the moving mold can be fixed, keeping the whole mold in an overall stable state.

[0021] Optionally, alignment notches are provided at the four corners of the moving mold, and an alignment plate is provided in the middle of the locking plate corresponding to the nearest adjacent alignment notch, and the alignment plate is fitted into the alignment notch.

[0022] By adopting the above technical solution, the alignment notch can be used to determine the alignment relationship between the fixed mold and the moving mold. At the same time, the locking plate can be accurately installed through the alignment plate. The locking plate can be first placed at the position of the alignment notch, and then the connection between the locking plate and the moving mold and the fixed mold can be made.

[0023] In summary, the first connection hole and the second connection hole are formed by the first core-pulling component and the second core-pulling component. After the moving mold and the fixed mold are separated from each other, the first core-pulling block and the second core-pulling block complete the demolding process through the core-pulling movement, smoothly completing the overall molding of the sensor connector without affecting the mutual separation process of the moving mold and the fixed mold. The setting of the molding top block cooperates with the molding process of the structure groove. At the same time, the molding top block also completes the demolding process after the sensor connector is molded through movement. A single structure realizes multiple functions. At the same time, the existence of the first core-pulling block and the second core-pulling block is also used for the placement of the sensing terminals during the molding of the sensor connector, realizing the composite molding of the sensing terminals and the plastic part of the sensor connector. The overall setting of the moving mold and the fixed mold, that is, the semi-circular structure notch corresponds to the moving mold, and the elastic clamping notch corresponds to the fixed mold, determines the molding without affecting the final demolding process.
