Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically to a mold positioning component for processing. Background Technology

[0002] The mold positioning component for processing is an important part of the mold used to accurately determine the relative positions of the various parts of the mold, ensuring that the mold can be accurately closed and formed during processing, and guaranteeing the dimensional accuracy and quality stability of the product.

[0003] Machining mold positioning components typically use positioning pins in conjunction with positioning holes to position the mold body. Some positioning pins are located at the bottom of the mold body. Since the positioning pins and positioning holes will wear out, the positioning pins need to be replaced periodically to ensure the stability of the mold. The existing positioning components for machining molds require lifting the mold to replace the positioning pins, making the maintenance of the positioning pins time-consuming and labor-intensive. Utility Model Content

[0004] The purpose of this utility model is to provide a positioning component for a processing mold, so as to solve the problem mentioned in the background art that the positioning pin on the existing positioning component for processing molds needs to be lifted to replace the positioning pin, which makes the maintenance of the positioning pin time-consuming and laborious.

[0006] Preferably, an observation mechanism is provided on the surface of the mold base. The observation mechanism includes a limiting block, which is in contact with the surface of the mold body. A mounting bolt is threaded onto the surface of the mold base. A guide plate is fixedly connected to the surface of the limiting block. A detection rod is slidably connected to the surface of the guide plate. An offset loop is provided on the surface of the detection rod. A connecting plate is fixedly connected to one end of the detection rod. A spring is fixedly connected to the surface of the connecting plate. The end of the spring away from the connecting plate is fixedly connected to the surface of the guide plate.

[0007] Preferably, a rectangular groove is provided at the bottom of the mold body, and a square nut is inserted into the rectangular groove at the bottom of the mold body. A circular hole is provided on one side of the rectangular groove of the mold body, and the limiting bolt passes through the circular hole of the mold body and is threadedly connected to the square nut.

[0008] Preferably, the surface of the mold base is provided with a rectangular hole, the top of the rectangular hole of the mold base is provided with a positioning hole, the positioning pin is connected to the positioning hole of the mold base through the rectangular hole of the mold base, four sets of positioning pins are provided, and the bottom of the positioning pin is provided with a limiting square hole.

[0009] Preferably, the rectangular hole of the mold base has guide grooves on both sides, the motor drives the bidirectional lead screw to rotate through the output shaft, the surface of the moving plate has threaded holes, the bidirectional lead screw is threaded to the threaded holes of the moving plate, the bidirectional lead screw drives the moving plate to slide on the guide groove of the mold base by rotation, the moving plate is provided in two sets, and the sliding directions of the two sets of moving plates are opposite, each set of moving plates is provided with two sets of limiting rods, and the limiting rods are inserted into the limiting square holes at the bottom of the positioning pins.

[0010] Preferably, the limiting block has a circular hole on its surface, the mold base has a threaded hole on its surface, the mounting bolt cooperates with the limiting block to restrict the guide plate on the surface of the mold base, the guide plate has a guide hole on its surface, the detection rod slides on the guide hole of the guide plate, and the spring force of the spring acts on the detection rod through the connecting plate.

[0011] Preferably, the side of the detection rod away from the connecting plate is connected to the bottom of the mold body. There are four sets of detection rods, and the four sets of detection rods are distributed in an "L" shape. There are two sets of offset loops, and the distance between the two sets of offset loops is less than the thickness of the guide plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This positioning component uses a rectangular hole in the mold base to insert a positioning pin, which then inserts a square nut into a rectangular groove at the bottom of the mold body. A limit bolt is threaded through a circular hole in the mold body and connected to the square nut, thus restricting the square nut to the rectangular groove at the bottom of the mold body. This limits the position of the positioning pin at the bottom of the mold body. The output shaft of the motor drives a bidirectional lead screw to rotate, which in turn drives a moving plate to slide on a guide groove in the mold base. The moving plate then drives a limit rod to slide into the limit square hole at the bottom of the positioning pin, thereby installing the positioning pin. The same principle applies to removing the positioning pin. The positioning pin can be replaced without lifting the mold body, making the maintenance of the positioning pin more time-saving and labor-saving.

[0014] This positioning component uses limit blocks and mounting bolts to mount the guide plate onto the surface of the mold base. The spring force causes the connecting plate to slide the detection rod to the bottom side of the mold body. When the mold body shifts, since the detection rod is always in contact with the bottom of the mold body, the mold body causes the detection rod to slide on the guide plate. The detection rod drives the offset loop, causing a set of offset loops to slide out from the guide hole of the guide plate. At this time, it can be determined which way the mold body has shifted. The four sets of detection rods can know the specific direction of the mold body's offset angle, allowing the operator to quickly determine whether the mold body has shifted.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 One embodiment provided by this utility model:

[0023] A mold positioning assembly for processing includes a mold body 1, a mold base 11 at the bottom of the mold body 1, a square nut 2 inserted into the bottom of the mold body 1, a limit bolt 21 threaded onto the surface of the square nut 2, a positioning pin 22 fixedly connected to the bottom of the square nut 2, a motor 23 fixedly connected to the surface of the mold base 11, a bidirectional lead screw 24 fixedly connected to the output shaft of the motor 23, a moving plate 25 threaded onto the surface of the bidirectional lead screw 24, a limit rod 26 fixedly connected to the surface of the moving plate 25, and the limit rod 26 inserted into the bottom of the positioning pin 22. This positioning assembly allows the positioning pin 22 to be replaced without lifting the mold body 1, thus making the maintenance of the positioning pin 22 more time-saving and labor-saving. After the positioning pin 22 wears down, it will cause the mold body 1 to shift on the mold base 11, thereby reducing the stability of the mold body 1 during use. Replacing the positioning pin 22 can ensure the stability of the mold body 1 on the mold base 11.

[0024] Furthermore, an observation mechanism is provided on the surface of the mold base 11. The observation mechanism includes a limiting block 3, which is connected to the surface of the mold body 1. A mounting bolt 31 is threadedly connected to the surface of the mold base 11. A guide plate 32 is fixedly connected to the surface of the limiting block 3. A detection rod 33 is slidably connected to the surface of the guide plate 32. An offset loop 34 is provided on the surface of the detection rod 33. A connecting plate 35 is fixedly connected to one end of the detection rod 33. A spring 36 is fixedly connected to the surface of the connecting plate 35. The end of the spring 36 away from the connecting plate 35 is fixedly connected to the surface of the guide plate 32. This observation mechanism can determine whether the mold body 1 has shifted on the mold base 11 by observing the offset loop 34. When the mold body 1 shifts, it is convenient to replace the positioning pin 22, so that the operator can quickly determine whether the mold body 1 has shifted.

[0025] Furthermore, a rectangular groove is provided at the bottom of the mold body 1, and a square nut 2 is inserted into the rectangular groove at the bottom of the mold body 1. A circular hole is provided on one side of the rectangular groove of the mold body 1, and a limiting bolt 21 passes through the circular hole of the mold body 1 and is threadedly connected to the square nut 2. The limiting bolt 21 restricts the square nut 2 to the rectangular groove at the bottom of the mold body 1, thereby restricting the position of the positioning pin 22 at the bottom of the mold body 1, so as to facilitate the positioning pin 22 to position the mold body 1.

[0026] Furthermore, a rectangular hole is provided on the surface of the mold base 11, and a positioning hole is provided at the top of the rectangular hole of the mold base 11. The positioning pin 22 is connected to the positioning hole of the mold base 11 through the rectangular hole of the mold base 11, so that the positioning pin 22 can be restricted to the bottom of the mold body 1 in the rectangular hole of the mold base 11 without lifting the mold body 1. There are four sets of positioning pins 22, and the bottom of the positioning pin 22 is provided with a limiting square hole. The four sets of positioning pins 22 can achieve precise positioning of the mold body 1 on the mold base 11.

[0027] Furthermore, guide grooves are provided on both sides of the rectangular hole of the mold base 11. The motor 23 drives the bidirectional lead screw 24 to rotate through the output shaft. Threaded holes are provided on the surface of the moving plate 25. The bidirectional lead screw 24 is threadedly connected to the threaded hole of the moving plate 25. The bidirectional lead screw 24 drives the moving plate 25 to slide on the guide groove of the mold base 11 through rotation. There are two sets of moving plates 25, and the sliding directions of the two sets of moving plates 25 are opposite. Each set of moving plates 25 is provided with two sets of limiting rods 26. There are a total of four sets of limiting rods 26. The limiting rods 26 are inserted into the limiting square holes at the bottom of the positioning pin 22. Since the square nut 2 is rectangular, the square nut 2 restricts the direction of the limiting square holes at the bottom of the positioning pin 22, so that multiple sets of limiting rods 26 can be inserted into the limiting square holes at the bottom of the positioning pin 22. At this time, the limiting rods 26 restrict the position of the positioning pin 22 on the mold body 1, thereby positioning the position of the mold body 1.

[0028] Furthermore, a circular hole is provided on the surface of the limiting block 3, and a threaded hole is provided on the surface of the mold base 11. The mounting bolt 31 cooperates with the limiting block 3 to restrict the guide plate 32 on the surface of the mold base 11. A guide hole is provided on the surface of the guide plate 32. The detection rod 33 slides on the guide hole of the guide plate 32. The elastic force of the spring 36 acts on the detection rod 33 through the connecting plate 35. The detection rod 33 and the spring 36 are parallel to each other. Under the elastic force of the spring 36, the detection rod 33 is pressed against the bottom of one side of the mold body 1.

[0029] Furthermore, the side of the detection rod 33 away from the connecting plate 35 is connected to the bottom of the mold body 1. There are four sets of detection rods 33, and the four sets of detection rods 33 are distributed in an "L" shape. There are two sets of offset loops 34, and the distance between the two sets of offset loops 34 is less than the thickness of the guide plate 32. When the bottom of the mold body 1 shifts, since the detection rods 33 are always connected to the bottom of the mold body 1, the mold body 1 drives the detection rods 33 to slide on the guide plate 32. The detection rods 33 drive the offset loops 34 so that one set of offset loops 34 slides out from the guide hole of the guide plate 32. At this time, it can be determined which way the mold body 1 shifts, and the four sets of detection rods 33 can know the specific direction of the offset angle of the mold body 1.

[0030] Working principle: The positioning pin 22 is inserted through the rectangular hole of the mold base 11, so that the positioning pin 22 inserts the square nut 2 into the rectangular groove at the bottom of the mold body 1. The limiting bolt 21 is threaded through the circular hole of the mold body 1 and the square nut 2, and the limiting bolt 21 restricts the square nut 2 to the rectangular groove at the bottom of the mold body 1, thereby restricting the position of the positioning pin 22 at the bottom of the mold body 1. The output shaft of the motor 23 drives the bidirectional lead screw 24 to rotate. The bidirectional lead screw 24 drives the moving plate 25 to slide on the guide groove of the mold base 11 through rotation. The moving plate 25 drives the limiting rod 26 to slide to the limiting square hole at the bottom of the positioning pin 22, thereby realizing the installation of the positioning pin 22. The same principle applies to the disassembly of the positioning pin 22. The positioning pin 22 can be replaced without lifting the mold body 1, making the maintenance of the positioning pin 22 more time-saving and labor-saving.

[0031] The guide plate 32 is installed on the surface of the mold base 11 by the limiting block 3 and the mounting bolt 31. The spring 36 causes the connecting plate 35 to drive the detection rod 33 to slide to the bottom side of the mold body 1. When the mold body 1 deviates, since the detection rod 33 is always in contact with the bottom of the mold body 1, the mold body 1 drives the detection rod 33 to slide on the guide plate 32. The detection rod 33 drives the offset loop 34 so that a set of offset loops 34 slide out from the guide hole of the guide plate 32. At this time, it can be determined which way the mold body 1 deviates. The four sets of detection rods 33 can know the specific direction of the offset angle of the mold body 1, so that the staff can quickly determine whether the mold body 1 has deviated.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
