Description

Technical Field

[0001] The utility model relates to a mold structure, in particular to a mold structure for trial-producing curved vehicle door glass guide rails. Background Art

[0002] With the development of vehicle technology, the overall performance requirements of door assemblies are constantly increasing, and higher requirements are being placed on the stability and structural strength of related accessories in the assembly. In order to ensure that the glass in the door system can be normally raised and lowered along the designed trajectory, a glass guide rail is added to the door system. The door glass guide rail is placed in the car door and acts as a limiter and guide for the car glass. The door glass guide rail needs to be pressed and folded by a mold structure. The existing bending mold usually consists of a punch and a die. The die has a fixed-size mold cavity for forming. The die is fixed and does not move. The punch is used to punch and fold the shape. This structure has a disadvantage, which is its low applicability. When the workpiece needs to be pressed and folded into door glass guide rails of different sizes, mold structures of different sizes are required, which invisibly increases production costs. Secondly, the existing mold structures are all fixed and cannot be adjusted in height as needed, which affects the production efficiency of the product. Utility Model Content

[0003] The purpose of the utility model is to provide a mold structure for trial-producing a curved vehicle door glass guide rail, so as to solve the problems raised in the above-mentioned background technology.

[0004] In order to solve the above technical problems, the utility model provides the following technical solutions: a mold structure for trial production of curved car door glass guide rails, including a punch body and a supporting body, a punch die is installed at the bottom of the punch body, a lifting mechanism is provided at the bottom of the inner groove of the supporting body, and a concave mold is provided at the top of the lifting mechanism through a sinking screw.

[0005] The opposite sides of the die are respectively provided with pressing fasteners in a threaded manner, and the ends of the pressing fasteners are tightly pressed into the pressing grooves on the side surfaces of the die. A plurality of pressing grooves are sequentially provided from top to bottom.

[0006] The pressing fastener comprises a threaded rod and a pressing portion, and the end of the threaded rod is mounted on the pressing portion through a rotating sleeve.

[0007] The pressing portion includes a front end pressing portion and a rear end pressing portion, the front end pressing portion is pressed into the pressing groove, and the rear end pressing portion is pressed on the side surface of the die.

[0008] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: the present invention provides a mold structure for trial-producing curved door glass guide rails, comprising a punch body and a supporting body, a punch die being installed at the bottom of the punch body, a lifting mechanism being provided at the bottom of the inner groove of the supporting body, and a die being provided at the top of the lifting mechanism through a sinking screw. On the one hand, both the punch die and the die can be disassembled and replaced. Therefore, when the workpiece needs to be folded into door glass guide rails of different sizes, only the mold structure needs to be replaced, thereby saving production costs invisibly. Secondly, the lifting mechanism can lift and lower the die, which has stronger applicability to the folding of different workpieces and improves the production efficiency of the product.

[0014] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0015] See also Figure 1-2 The utility model provides a technical solution: a mold structure for trial-producing curved door glass guide rails, including a punch body 1 and a supporting body 2, a punch body 1 is installed at the bottom of the punch body 1, and a lifting mechanism 4 is provided at the bottom of the inner groove of the supporting body 2. The lifting mechanism 4 is composed of multiple cylinders and a support plate. A die 6 is provided at the top of the lifting mechanism 4 through a sinking screw 5, that is, the sinking screw 5 is screwed into the threaded through groove of the die 6 and the threaded groove of the support plate, so that the die 6 can be fixedly installed on the lifting mechanism 4. On the one hand, the die 6 can be replaced, and at the same time, the die 6 can be lifted and lowered, killing two birds with one stone.

[0016] The opposite sides of the die 6 are respectively provided with a pressing fastener 7 in a threaded manner. The end of the pressing fastener 7 is tightly pressed in the pressing groove 8 on the side of the die 6. The pressing groove 8 is sequentially provided with multiple pressing fasteners 7 from top to bottom, so that the pressing fastener 7 can adapt to the lifting and lowering of the die 6. After the die 6 is raised or lowered to a certain height, it is ensured that the end of the pressing fastener 7 can be pressed into the pressing groove 8. The pressing fastener 7 includes a threaded rod 71 and a pressing portion 72. The end of the threaded rod 71 is mounted on the pressing portion 72 through a rotating sleeve. The pressing portion 72 includes a front pressing portion 721 and a rear pressing portion 722. The front pressing portion is pressed in the pressing groove 8, and the rear pressing portion 722 is pressed on the side of the die 6.

[0017] The specific working process of the pressing fastener 7 is to screw the threaded rod 71 to push the pressing part 72 forward until the front pressing part of the pressing part 72 is pressed into the pressing groove 8, and the rear pressing part 722 is pressed on the side of the die 6. At this time, the entire pressing part 72 can firmly hold the die 6 from the surrounding side, which is beneficial to the stability of the entire mold structure during the folding process of the workpiece 9.

[0018] like Figure 3 As shown, after the specifications of the punch die 3 and the die 6 are changed, the workpiece 9 can be folded into different specifications, and after the workpiece is folded and formed, it can be demolded manually, that is, the staff knocks on the die 6, and the die 6 vibrates to smoothly demold. This application has stronger applicability to the folding of different workpieces, and improves the production efficiency of the product.
