[0002] In automobile manufacturing, the automobile is composed of a main frame and various parts. The main frame is fixedly connected with various parts through brackets. The automobile bracket is generally manufactured by die stamping.

[0003] The automobile bracket is punched and processed by closing the upper and lower molds. The upper and lower molds are constantly in use, and there is constant wear and tear between the two molds. The wear of the upper and lower molds will cause the docking accuracy to gradually decrease. When the upper and lower molds drop to a certain extent, the errors of the hole positions of the automobile bracket are too large to be used, resulting in the scrapping of the automobile bracket. Failure to maintain the mold docking accuracy in time will produce a large number of unqualified brackets. Summary of the invention

[0004] The disclosed embodiment relates to a production mold for an automobile bracket with precise docking. The opposing photoelectric sensors of the lower mold and the upper mold perform docking monitoring to ensure the accuracy of the docking between the lower mold and the upper mold. After the docking accuracy of the lower mold and the upper mold decreases, the opposing photoelectric sensors issue an alarm, and the maintenance operations of the lower mold and the upper mold are performed in time to avoid the situation where the accuracy of the lower mold and the upper mold decreases and unqualified automobile brackets are manufactured, thereby reducing the scrap cost of unqualified automobile brackets.

[0005] According to a first aspect of the present disclosure, a mold for producing a car bracket with precise docking is provided, which specifically includes: a lower mold, an upper mold and a corresponding photoelectric sensor. An upper mold is provided above the lower mold, and corresponding photoelectric sensors are provided on the sides of the lower mold and the upper mold. Side V-groove plates are fixed on both sides of the lower mold, a lower discharging inclined frame is fixed at the lower part of the lower mold, a middle push rod is slidably provided on both sides of the lower mold, and a lower connecting elastic member with a spiral spring structure is fixed at the lower part of the middle push rod.

[0006] In at least some embodiments, the tail end of the lower connecting spring is fixedly connected to the lower mold, the middle push rod and the lower discharging inclined frame are connected through, and the lower connecting spring pulls the middle push rod to reset and move backward, thereby realizing the reciprocating movement of the middle push rod.

[0007] In at least some embodiments, side V-shaped convex plates are fixed to both sides of the upper mold, and lower inclined plane frames are fixed to both sides of the lower part of the upper mold.

[0008] In at least some embodiments, the side V-shaped convex plate is located vertically above the side V-shaped groove plate, and when the lower mold and the upper mold are closed, the side V-shaped convex plate and the side V-shaped groove plate remain in contact, and the side V-shaped convex plate and the side V-shaped groove plate perform auxiliary positioning for docking.

[0009] In at least some embodiments, the lower inclined frame is slidably connected to the upper mold, the lower end inclined surface of the lower inclined frame and the tail of the middle push rod slide, and the inclined surface of the lower inclined frame guides the middle push rod to move forward horizontally while moving downward, and the middle push rod moves to the front of the lower discharge inclined frame.

[0010] In at least some embodiments, the reflecting photoelectric sensor is slidably connected to the inner connecting frame, an outer fixed cover plate is slidably arranged on the outer side of the inner connecting frame, the outer fixed cover plate and the inner connecting frame are fixed with screws, and the middle part of the outer fixed cover plate fits the outer side of the reflecting photoelectric sensor.

[0011] In at least some embodiments, the sides of the lower mold and the upper mold are fixed with internal connecting frames. When the lower mold and the upper mold are closed, the opposing photoelectric sensors of the lower mold and the upper mold are vertically aligned, and the two opposing photoelectric sensors are docked by laser to ensure the accuracy of the docking of the lower mold and the upper mold. After the docking accuracy of the lower mold and the upper mold decreases, and the lower mold and the upper mold are worn and offset, the opposing photoelectric sensors are also offset, and the lasers between the two opposing photoelectric sensors cannot be docked and an alarm is issued.

[0012] The utility model provides a production mold for automobile brackets with precise docking, which has the following beneficial effects:

[0013] The photoelectric sensors of the lower mold and the upper mold are used to monitor the docking to ensure the accuracy of the docking between the lower mold and the upper mold. When the docking accuracy between the lower mold and the upper mold decreases, the photoelectric sensors will give an alarm and perform maintenance operations on the lower mold and the upper mold to avoid the lower mold and the upper mold from manufacturing a large number of unqualified automobile brackets and reduce the scrap cost of unqualified automobile brackets.

[0014] During the downward movement of the upper mold and the lower inclined frame, the lower inclined frame guides the middle push rod to move forward, and the middle push rod pushes and moves the automobile bracket where the lower discharge inclined frame stays, thereby preventing the automobile bracket where the lower discharge inclined frame stays from silting up and getting blocked.

Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the described embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Example 1: Please refer to Figures 1 to 6 :

[0028] The utility model proposes a production mold for an automobile bracket with precise docking, comprising: a lower mold 1, an upper mold 2 and a corresponding photoelectric sensor 3, side V-shaped groove plates 101 are fixed on both sides of the lower mold 1, a lower discharging inclined frame 102 is fixed on the lower part of the lower mold 1, a middle push rod 103 is slidably provided on both sides of the lower part of the lower mold 1, a lower connecting elastic member 104 with a spiral spring structure is fixed on the lower part of the middle push rod 103, the tail end of the lower connecting elastic member 104 is fixedly connected to the lower mold 1, the middle push rod 103 and the lower discharging inclined frame 102 are connected through, the lower connecting elastic member 104 pulls the middle push rod 103 to reset and retreat, so as to realize the reciprocating movement of the middle push rod 103, an upper mold 2 is arranged above the lower mold 1, and both sides of the upper mold 2 Both are fixed with side V-shaped convex plates 201, and lower inclined frames 202 are fixed on both sides of the lower part of the upper mold 2. The side V-shaped convex plates 201 are vertically above the side V-shaped groove plates 101. When the lower mold 1 and the upper mold 2 are closed, the side V-shaped convex plates 201 and the side V-shaped groove plates 101 remain in contact with each other, and the side V-shaped convex plates 201 and the side V-shaped groove plates 101 perform auxiliary positioning for docking. The sides of the lower mold 1 and the upper mold 2 are both provided with opposing photoelectric sensors 3, and the opposing photoelectric sensors 3 are slidably connected to the inner connecting frame 301. An outer fixed cover plate 302 is slidably arranged on the outer side of the inner connecting frame 301, and the outer fixed cover plate 302 and the inner connecting frame 301 are fixed with screws, and the middle part of the outer fixed cover plate 302 is in contact with the outer side of the opposing photoelectric sensor 3.

[0029] In the disclosed embodiment, the lower inclined frame 202 is slidably connected to the upper mold 2, the lower end inclined surface of the lower inclined frame 202 and the tail of the middle push rod 103 slide, and the inclined surface of the lower inclined frame 202 guides the middle push rod 103 to move forward horizontally while moving downward, and the middle push rod 103 moves to the front of the lower discharge inclined frame 102, and the middle push rod 103 pushes the car bracket where the lower discharge inclined frame 102 stops to move, thereby promoting the discharge movement of the car bracket in the middle position of the lower discharge inclined frame 102 and reducing the situation where the car bracket of the lower discharge inclined frame 102 stops and is blocked.

[0030] In the disclosed embodiment, an inner connecting frame 301 is fixed to the sides of the lower mold 1 and the upper mold 2. When the lower mold 1 and the upper mold 2 are closed, the opposing photoelectric sensors 3 of the lower mold 1 and the upper mold 2 are vertically aligned, and the two opposing photoelectric sensors 3 are docked by laser to ensure the accuracy of the docking of the lower mold 1 and the upper mold 2. After the docking accuracy of the lower mold 1 and the upper mold 2 decreases, the opposing photoelectric sensors 3 also shift after the lower mold 1 and the upper mold 2 are worn and offset, and the lasers between the two opposing photoelectric sensors 3 cannot be docked. The opposing photoelectric sensors 3 issue an alarm to avoid the decrease in the docking accuracy of the lower mold 1 and the upper mold 2, which leads to the production of a large number of unqualified automobile brackets.

[0031] Embodiment 2, on the basis of embodiment 1, the middle push rod 103 is a rectangular plate structure, and the middle push rod 103 is directly on the lower discharging inclined frame 102 for sliding. The lower discharging inclined frame 102 with a rectangular plate structure has a larger area, and the pushing range of the automobile bracket staying on the lower discharging inclined frame 102 is larger, and the effect of moving and cleaning the automobile bracket staying on the lower discharging inclined frame 102 is better, thereby further reducing the residue of the automobile bracket.

[0032] The working principle of this embodiment is as follows: the lower mold 1 and the stamping equipment are fixed, the upper mold 2 and the stamping slide of the stamping equipment are fixed, and the stamping equipment drives the upper mold 2 and the lower mold 1 to close and perform the stamping operation of the middle steel plate, and the upper mold 2 and the lower mold 1 punch out the required bracket shape, and the bracket falls onto the lower inclined frame 202 and slides outward along the inclined surface of the lower inclined frame 202. During the downward movement of the upper mold 2, the upper mold 2 and the lower inclined frame 202 move downward synchronously, and the lower inclined surface of the lower inclined frame 202 and the tail of the middle push rod 103 slide. The inclined surface of the lower inclined frame 202 guides the middle push rod 103 to move forward horizontally while moving downward, and the middle push rod 103 moves to the front of the lower discharging inclined frame 102, and the middle push rod 103 pushes and moves the automobile bracket where the lower discharging inclined frame 102 stays, so as to avoid the situation where the automobile bracket where the lower discharging inclined frame 102 stays is blocked by siltation, eliminating the need for personnel to clean the blocked automobile bracket;

[0033] The lower mold 1 and the upper mold 2 are connected by the opposite photoelectric sensor 3 arranged on the outside to monitor the connection. The two opposite photoelectric sensors 3 are connected by laser to ensure the accuracy of the connection between the lower mold 1 and the upper mold 2. After the connection accuracy of the lower mold 1 and the upper mold 2 decreases, the lower mold 1 and the upper mold 2 are worn and offset, and the opposite photoelectric sensor 3 is also offset. The lasers between the two opposite photoelectric sensors 3 cannot be connected. The opposite photoelectric sensor 3 alarms and maintenance operations must be performed on the lower mold 1 and the upper mold 2. The maintenance of the lower mold 1 and the upper mold 2 is more timely, avoiding the situation where a large number of unqualified automobile brackets are manufactured due to the decrease in the connection accuracy of the lower mold 1 and the upper mold 2, thereby reducing the cost of unqualified automobile bracket scrap.
