Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a mold with positioning function. Background Technology

[0002] The production of products such as terminal connectors generally adopts a continuous material structure with single-sided or double-sided material stripping. The mold structure in the existing technology is relatively simple, and the positioning and stripping design is relatively basic. With the rapid iteration of manufacturing technology, the market has put forward higher requirements for product precision, production speed and cost optimization. Traditional processes are no longer able to meet the high standards of modern production.

[0003] In existing technologies, the positioning accuracy of the material strip is insufficient, which can easily lead to product position deviation and dimensional tolerance exceeding requirements during stamping or cutting. This results in frequent mold repairs, and the reference point is easily lost during the mold repair process, creating a chain of production problems. In addition, the material strip is prone to jamming and failure to unload during the conveying process, requiring a reduction in production speed, which seriously restricts the production speed. Utility Model Content

[0004] The purpose of this utility model is to provide a mold with a positioning function, which can solve the above-mentioned technical problems. This utility model provides a mold with positioning function, including: an installation structure and a placement structure, both of which are connected to a molding machine; a plurality of positioning structures, which are inserted into positioning grooves on the installation structure; wherein the positioning structure includes: a stripping sleeve disposed in the positioning groove, and a guide pin inserted in the stripping sleeve, one end of the guide pin being placed in the positioning groove; a reset body, one end of which is fixed to the installation structure and the other end of which is connected to the stripping sleeve.

[0005] As a further technical solution, the stripper sleeve includes: a sleeve body, which is set in a positioning groove, and a positioning cavity is formed in the sleeve body; one end of the guide pin is placed in the positioning groove, and the other end passes through the sleeve body and is placed in the positioning cavity; the other end of the reset body is connected to the sleeve body.

[0006] As a further technical solution, the stripper sleeve is slidably connected to the positioning groove.

[0007] As a further technical solution, in the mold-open state, one end of the stripper sleeve is placed outside the positioning groove; in the mold-closed state, the stripper sleeve is placed inside the positioning groove.

[0008] As a further technical solution, the reset body is fitted onto the guide pin.

[0009] As a further technical solution, the guide pin includes: a rod body and a guide head, with the guide head fixed to one end of the rod body.

[0010] As a further technical solution, the diameter of the end of the guide head away from the rod gradually decreases.

[0011] As a further technical solution, a limiting platform is provided on the rod body, and in the installed state, the limiting platform is in contact with the bottom of the positioning groove.

[0012] As a further technical solution, the installation structure includes a stripper plate and a stop plate. The stop plate is connected to the forming machine, and the stripper plate is set on the stop plate. The positioning groove is opened on the stripper plate, and one end of the resetting body is set inside the stop plate, while the other end is connected to the stripper sleeve.

[0013] As a further technical solution, the reset body is a spring.

[0014] The technical solution of this utility model, through the design of a positioning structure, places one end of the guide pin in the positioning groove and the other end in conjunction with the stripper sleeve to form a stable guide, which can accurately limit the material strip, effectively reducing the offset during material strip conveying and stamping, and ensuring that the product dimensional tolerances meet production requirements. At the same time, precise positioning can avoid frequent mold repairs caused by inaccurate positioning, reduce the chain production problems caused by the loss of reference points, reduce maintenance frequency and costs, and ensure production continuity.

[0015] Furthermore, in this invention, one end of the reset body is fixed to the mounting structure, while the other end is fitted with a stripper sleeve. This allows the stripper sleeve to elastically reset during mold opening and closing, actively assisting the material strip in detaching from the mold and fundamentally reducing material jamming and failure to detach. It eliminates the need to mitigate malfunctions by slowing down the process, maintaining a high-efficiency production rhythm, breaking through the speed limitations of traditional processes, and significantly improving production efficiency.

[0022] like Figure 1-5As shown, the present invention proposes a mold with positioning function, comprising: an installation structure 101 and a placement structure 102. Both the installation structure 101 and the placement structure 102 are connected to a molding machine. Driven by the molding machine, the installation structure 101 can move towards the position of the placement structure 102, thereby enabling the positioning structure 200 to position the product on the placement structure 102. Specifically, the product is fixed by a roller feeder or a clamp feeder and then placed between the installation structure 101 and the placement structure 102 for movement. After reaching the position between the placement structure 102 and the installation structure 101, the molding machine drives the installation structure 101 to move towards the position of the placement structure 102, and several positioning structures 200 are inserted into the positioning holes on the material strip 400 to achieve positioning of the material strip 400. After the material strip 400 is positioned, corresponding operations are performed. It should be noted that components such as punches or cutters can be provided on the mounting structure 101 to achieve stamping or cutting of the strip 400 during the operation of the mounting structure 101; wherein, punches or cutters adopt existing technology and are not shown in the accompanying drawings of this utility model. Several positioning structures 200 are inserted into positioning grooves 300 on the mounting structure 101. Each positioning structure 200 includes: a stripping sleeve 201 disposed within the positioning groove 300, and a guide pin 202 inserted within the stripping sleeve 201, one end of which is positioned within the positioning groove 300; a resetting body 203 with one end fixed to the mounting structure 101 and the other end connected to the stripping sleeve 201; when the material strip 400 is placed between the mounting structure 101 and the placement structure 102, the mounting structure 101 moves towards the placement structure 102 under the drive of the molding machine, and the several positioning structures 200... When the strip 400 on the placement structure 102 comes into contact with the strip 400, the stripping sleeve 201 first contacts the strip 400. As the installation structure 101 continues to move, the stripping sleeve 201 will enter the positioning groove 300 and squeeze the reset body 203 during the process of entering the positioning groove 300. As the stripping sleeve 201 enters the positioning groove 300, the guide pin 202 is inserted into the positioning hole on the strip 400 to achieve positioning of the strip 400. After the guide pin 202 is inserted into the positioning hole, the punch or cutter will contact the strip 400 to achieve punching or cutting of the strip 400. After stamping or cutting is completed, the mounting structure 101 moves away from the placement structure 102 under the drive of the molding machine. As the mounting structure 101 separates from the placement structure 102, the force acting on the stripper sleeve 201 disappears. Then, under the push of the reset body 203, the stripper sleeve 201 extends out of the positioning groove 300, and pushes the strip 400 away from the guide pin 202 during the extension process, completing the demolding operation of the strip 400 and the guide pin 202. In this utility model, it is preferred to provide two positioning structures 200; the reset body 203 is preferably a spring.

[0023] The technical solution of this utility model, through the design of the positioning structure 200, has a guide pin 202 with one end placed in the positioning groove 300 and the other end working with the stripper sleeve 201 to form a stable guide, which can accurately limit the material strip 400, effectively reducing the offset of the material strip 400 during conveying and stamping, and ensuring that the product dimensional tolerances meet production requirements. At the same time, precise positioning can avoid frequent mold repairs caused by inaccurate positioning, reduce the chain production problems caused by the loss of reference points, reduce maintenance frequency and maintenance costs, and ensure production continuity.

[0024] Furthermore, in this invention, one end of the reset body 203 is fixed to the mounting structure 101, and the other end is fitted with a stripper sleeve 201. This allows the stripper sleeve 201 to elastically reset during mold opening and closing, actively assisting the material strip 400 in detaching from the mold, thus reducing material jamming and failure to detach from the mold at the source. Without needing to reduce speed to avoid malfunctions, this invention maintains a high-efficiency production rhythm, breaks through the speed limitations of traditional processes, and significantly improves production efficiency.

[0025] like Figure 3 and Figure 5 As shown, the stripping sleeve 201 includes a sleeve body 211 disposed in the positioning groove 300, and a positioning cavity 212 is formed in the sleeve body 211; one end of the guide pin 202 is placed in the positioning groove 300, and the other end passes through the sleeve body 211 and is placed in the positioning cavity 212; the other end of the reset body 203 is connected to the sleeve body 211. Specifically, the mounting structure 101 includes a stripper plate 111 and a stop plate 112. The stop plate 112 is connected to the molding machine, and the stripper plate 111 is mounted on the stop plate 112. A positioning groove 300 is formed on the stripper plate 111. One end of the reset body 203 is located inside the stop plate 112, and the other end is connected to the stripper sleeve 201. The stripper sleeve 201 is slidably connected to the positioning groove 300. In the mold-opening state, one end of the stripper sleeve 201 is placed outside the positioning groove 300. In the mold-closing state, the stripper sleeve 201 is placed inside the positioning groove 300. In this way, when the mold is closed, it can be ensured that the sleeve 211 first contacts the strip 400, and as the mounting structure 101 continues to move, the sleeve 211 enters the positioning groove 300, and the guide pin 202 is inserted into the positioning hole. Specifically, one end of the guide pin 202 is placed in the positioning groove 300 and contacts the stop plate 112, thereby restricting the guide pin 202 within the positioning groove 300 and preventing the guide pin 202 from moving; the reset body 203 is also restricted between the sleeve 211 and the stop plate 112; thus, during operation, after the sleeve 211 contacts the material strip 400, it can slide on the guide pin 202 and compress the reset body 203; at the same time, under the restriction of the guide pin 202, the stability of the sleeve 211 during the sliding process can be ensured; like Figure 3As shown, the reset body 203 is sleeved on the guide pin 202. When the sleeve 211 slides in the positioning groove 300, it squeezes the reset body 203. Since the reset body 203 is sleeved on the guide pin 202, the guide pin 202 can prevent the reset body 203 from lateral displacement, ensuring that the sleeve 211 is subjected to uniform force during sliding, and preventing the reset body 203 from changing the thrust on the sleeve 211 after deformation, which would cause the sleeve 211 to squeeze and deform the material strip 400.

[0026] like Figure 4 As shown, a groove 113 and a pinhole 114 are provided on the stripper plate 111. Specifically, both the groove 113 and the pinhole 114 are located at the bottom of the positioning groove 300 and are connected to the positioning groove 300. After the stripper sleeve 201 and the guide pin 202 are installed, they are placed in the groove 113 and the pinhole 114 respectively. Figure 5 As shown, an opening 213 is provided on the sleeve 211, which divides the sleeve 211 into two limiting arms. After the sleeve 211 is installed, the two limiting arms are respectively placed in the sliding groove 113, and the sliding groove 113 limits the two limiting arms laterally. Furthermore, the lateral limiting of the limiting arms by the sliding groove 113 cooperates with the longitudinal support at the bottom of the positioning groove 300 to prevent the sleeve 211 from falling out of the positioning groove 300. In addition, the guide pin 202 includes a rod 221 and a guide head 222, with the guide head 222 fixed to one end of the rod 221. When the guide pin 202 contacts the positioning hole on the material strip 400, it can be preferentially inserted into the positioning hole through the guide head 222. The diameter of the end of the guide head 222 away from the rod 221 gradually decreases. In this way, when the guide head 222 is inserted into the positioning hole, it can guide the rod 221 into the positioning hole, ensuring the accuracy of the guide pin 202 entering the positioning hole.

[0027] like Figure 3 As shown, a limiting platform 223 is provided on the rod 221. In the installed state, the limiting platform 223 is in contact with the bottom of the positioning groove 300. Specifically, after the rod 221 is placed in the positioning groove 300, the guide head 222 passes through the pin hole 114 and is placed outside the positioning groove 300. The limiting platform 223 is in contact with the bottom of the positioning groove 300 to prevent the rod 221 from leaving the positioning groove 300. After the stop plate 112 is fixed to the stripper plate 111, the other end of the rod 221 is blocked by the stop plate 112. Thus, with the cooperation of the stop plate 112 and the bottom of the positioning groove 300, the guide pin 202 is limited.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
