Description

Technical Field

[0001] The utility model relates to the technical field of mold positioning, in particular to a mold positioning device for a vehicle body structural part. Background Art

[0002] Body structure molds are important tools for manufacturing automobile body parts. Their design and manufacturing are crucial to ensure the perfect fit between parts and body structure. According to the way of use and structural characteristics, body structure molds can be mainly divided into two categories, stamping molds and composite molds.

[0003] Upon investigation, the Chinese utility model patent with publication number CN211727216U discloses a mold positioning device, which first uses a positioning column and a positioning hole to position the mold. When the position of the mold is adjusted to a suitable position, the fixed blocks on both sides of the positioning block are fixedly connected to the positioning block and the mold, so that the clamping effect of the fixed blocks on both sides can prevent the mold from being eccentric. Moreover, the mold positioning device is fast in positioning, simple in structure and debugging, and low in cost; however, in actual use, if the punch or mold is slightly skewed, the positioning column can also enter the positioning hole, but during the movement, the positioning column will produce a certain amount of friction with the positioning hole, which will cause scratches on the positioning column and the positioning hole, and this situation is difficult to be discovered by the staff.

[0004] Therefore, the utility model provides a vehicle body structural component mold positioning device to solve the above-mentioned problem. Utility Model Content

[0005] 1. Technical issues to be solved

[0006] The utility model provides a positioning device for a mold of a vehicle body structural part, aiming to solve the problems in the background technology that the existing positioning column is skewed and difficult to find.

[0007] (II) Technical solution

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a vehicle body structural part mold positioning device, comprising a mold table, a punch head arranged at the driving end of the mold table, and a mold base arranged on the inner side of the mold table and directly below the punch head, wherein one end of the mold base close to the punch head is provided with a plurality of positioning columns located at the edge of the mold groove.

[0009] In order to solve the problem of judging whether the positioning column is crooked, a connecting column is fixedly installed at one end of the positioning column away from the mold seat, and a receiving groove is provided at one end of the connecting column away from the positioning column. The outer wall of the connecting column is provided with a plurality of inclined through holes distributed in a linear array and connected to the receiving groove. A measuring mechanism is provided in the through hole, and a spinning block is screwed in the receiving groove. The connection between the positioning column and the positioning groove can be accurately measured by the measuring mechanism in the through hole, and the staff can find problems by regular inspections, ensuring that the entire mold is used more accurately.

[0010] Preferably, in order to solve the problem of measuring the skewness of the positioning column, the measuring mechanism includes a ball movably installed in the through hole, a push plate slidably installed in the through hole, and an insertion rod fixedly installed on the push plate at one end away from the ball. The ball contacts the positioning groove and if the positioning column is skewed, the ball can drive the insertion rod to move, so as to observe the skewness.

[0011] Preferably, in order to understand the movement of the plunger, a marking line is provided on the plunger, through which the movement distance of the plunger can be determined, thus ensuring more accurate measurement.

[0012] Preferably, in order to solve the problem of direct observation of the tilting condition, the spinning block is provided with a plurality of display mechanisms distributed in a linear array and arranged opposite to the through hole, and an operating mechanism is provided at one end of the spinning block away from the connecting column. The tilting condition of the positioning column can be directly observed through the display mechanism, so that the staff can find the problem more intuitively.

[0013] Preferably, in order to solve the display problem of the skewed positioning column, the display mechanism includes a plurality of installation grooves arranged in a linear array on the spinning block and ink pads bonded in the installation grooves. By inserting the rod into the ink pad, holes will be left on the ink pad, so that the staff can find the skew problem in time, which is more convenient to use.

[0014] Preferably, in order to solve the problem of disassembling the spinning block, the operating mechanism includes a clearance groove provided at one end of the spinning block away from the connecting column and a rotating handle fixedly installed in the clearance groove. The rotating handle can drive the spinning block to rotate so as to realize the operation of disassembling the spinning block.

[0015] Preferably, in order to solve the problem of normal use of the connecting column and the positioning column, the end of the rotating handle away from the giving way groove is flush with the end surface of the spinning block. Through the flush setting of the rotating handle, the connecting column and the positioning column can be normally inserted into the positioning groove for use.

[0016] (III) Beneficial effects

[0017] The vehicle body structural part mold positioning device has a simple structure and is easy to use. The measuring mechanism ensures that if the positioning column is skewed during the contact between the punch head and the mold seat, the ball will immediately contact and slide with the inner wall of the positioning groove, thereby triggering real-time detection of the movement of the push plate and the insertion rod. The skewness of the punch head can be discovered in time to avoid production accidents and product quality problems caused by the skewness. At the same time, through the mark left by the insertion rod in the ink, the staff can intuitively judge whether the positioning column is skewed. This visual monitoring method is simple and fast, and does not require complex detection equipment, thereby reducing the monitoring cost. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0024] Example 1

[0025] The utility model provides a vehicle body structural part mold positioning device, such as Figure 1-4As shown, the mold positioning device includes a mold table 1, a punch head 2 arranged at the driving end of the mold table 1, and a mold base 3 arranged at the inner side of the mold table 1 and directly below the punch head 2. The mold base 3 is provided with a plurality of positioning columns 4 located at the edge of the mold groove at one end close to the punch head 2;

[0026] A connecting column 41 is fixedly mounted on one end of the positioning column 4 away from the mold base 3, and a groove 42 is formed on the end of the connecting column 41 away from the positioning column 4. The outer wall of the connecting column 41 is provided with a plurality of inclined through holes 43 distributed in a linear array and connected to the groove 42, a measuring mechanism 44 is arranged in the through hole 43, and a spinning block 5 is screwed in the groove 42.

[0027] When in use, during normal production, the driving assembly on the mold table 1 can drive the punch head 2 to move, so that the punch head 2 contacts the mold groove on the mold base 3 and then punches the internal material. During the contact between the punch head 2 and the mold base 3, the positioning column 4 and the connecting column 41 can enter the positioning groove on the punch head 2 to guide and position the punch head 2 to prevent it from being skewed, and the measuring mechanism 44 in the through hole 43 on the connecting column 41 can detect whether the positioning column 4 is skewed when entering the positioning groove.

[0028] Specifically, the measuring mechanism 44 includes a ball 441 movably installed in the through hole 43, a push plate 442 slidably installed in the through hole 43, and an insertion rod 443 fixedly installed on the push plate 442 at an end away from the ball 441; the through hole 43 is located at an end away from the receiving groove 42 and is inclined downward. At this time, under the action of gravity, the ball 441 can enter the lower end of the through hole 43, and at this time, the outer wall of the ball 441 is flush with the outer wall of the positioning column 4. As the connecting column 41 enters the positioning groove, if it is skewed, the ball 441 can first contact the inner wall of the positioning groove and be squeezed. At this time, the ball 441 can slide along the through hole 43 and push the push plate 442 and the insertion rod 443.

[0029] Furthermore, a marking line 444 is provided on the insertion rod 443 ; the marking line 444 on the insertion rod 443 protrudes from the insertion rod 443 , so that the moving distance of the insertion rod 443 can be read.

[0030] Example 2

[0031] Different from Example 1, the spinning block 5 is provided with a plurality of display mechanisms 51 distributed in a linear array and arranged opposite to the through hole 43, and an operating mechanism 52 is provided at the end of the spinning block 5 away from the connecting column 41. The display mechanism 51 includes a plurality of mounting grooves 511 distributed in a linear array opened on the spinning block 5 and an ink pad 512 bonded in the mounting grooves 511.

[0032] When in use, before installing the spinning block 5, the surface of the insertion rod 443 and the ink pad 512 in the installation groove 511 can be brushed with oil. After the treatment is completed, the spinning block 5 can be installed in the receiving groove 42 for use. The insertion rod 443 can be inserted into the ink pad 512 when driven by the ball 441, and the marking line 444 can leave an imprint in the ink pad 512. The staff only needs to check the ink pad 512 regularly. Since the ink pad 512 and the insertion rod 443 are both brushed with oil, the insertion rod 443 can still be reset after the positioning column 4 is separated from the positioning groove under the action of gravity after the insertion of the ink pad. When checking, the staff can take the spinning block 5 out of the receiving groove 42, observe whether there are holes on the ink pad 512 and observe the marks left by the marking line 444 to determine whether the positioning column 4 is skewed.

[0033] Specifically, the operating mechanism 52 includes a clearance groove 521 opened at the end of the spinning block 5 away from the connecting column 41 and a turning handle 522 fixedly installed in the clearance groove 521, and the end of the turning handle 522 away from the clearance groove 521 is flush with the end surface of the spinning block 5; when operating the spinning block 5, the turning handle 522 can be rotated to drive the spinning block 5 to rotate and realize disassembly and assembly.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
