Description

Technical Field

[0001] The utility model relates to a mould structure, in particular to a curved vehicle door glass guide rail mould structure which is easy to demould. Background Art

[0002] In short, a mold is a tool used to make molded objects. This tool is composed of various parts, and different molds are composed of different parts. The mold used for stamping often requires a demolding structure to remove the workpiece after the mold is closed.

[0003] The existing mold demolding structure has the following problems when in use: since the product will fit into the inner wall of the mold after molding, there is a certain friction between it and the inner wall of the mold. When the product is bonded to the mold, the staff needs to knock on the mold and vibrate the mold to successfully demold it. The demolding process is relatively cumbersome and laborious, and the demolding efficiency is low. Utility Model Content

[0004] The purpose of the utility model is to provide a curved vehicle door glass guide rail mold structure that is easy to demould, so as to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a curved car door glass guide rail mold structure that is easy to demold, including a punch die and a die, a bending insert is provided in the die, one side of the bending insert is an inclined surface, a component through hole is provided on one side of the die, a support column is vertically installed on the inclined surface, the support column passes through the component through hole and is connected to the bending insert, a spring member is provided between the end of the support column and the side wall of the die, and the two end ends of the spring member are respectively movably installed with limiting members, and the ends of the two limiting members are respectively hinged to the end of the support column and the side wall of the die.

[0006] The limiting component includes a connecting column, a threaded sleeve and a limiting threaded rod, and the connecting column is installed together with the limiting threaded rod through the threaded sleeve.

[0007] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: a spring member is provided between the end of the support column and the side wall of the die, and the elastic force of the spring member is utilized to rotate the bending insert upward to a certain angle. At this time, the folded workpiece will be ejected by the bending insert. When the product is bonded to the mold, there is no need for the staff to knock the mold, the demolding process is simple, and the demolding efficiency is high. BRIEF DESCRIPTION OF THE DRAWINGS

[0008] The accompanying drawings are used to provide a further understanding of the present invention and constitute a part of the specification. In the accompanying drawings:

[0012] In the figure: 1 punching die; 2 bending insert; 3 die; 4 component through hole; 5 support column; 6 spring member; 7 limit member; 71 connecting column; 72 threaded sleeve; 73 limit threaded rod; 8 movable groove; 9 workpiece. DETAILED DESCRIPTION

[0013] The following will be combined with the accompanying 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.

[0014] See also Figure 1 The utility model provides a technical solution: a curved car door glass guide rail mold structure that is easy to demould, including a punch die 1 and a die 3. A bending insert 2 is provided in the die 3. One side of the bending insert 2 is an inclined surface. A component through hole 4 is provided on one side of the die 3. A support column 5 is vertically installed on the inclined surface. The support column 5 passes through the component through hole 4 and is connected to the bending insert 2. A spring member 6 is provided between the end of the support column 5 and the side wall of the die 3. The ends of the spring member 6 are respectively movably installed with limit members 7. The ends of the two limit members 7 are respectively hinged to the end of the support column 5 and the side wall of the die 3.

[0015] like Figure 1 As shown, when the die 1 is pressed down, the die 1 presses the bending insert 2 to rotate it downward to the bottom, and the spring member 6 is stretched until the bending is completed in the die cavity. The die 1 is lifted. At this time, the bending insert 2 rotates upward due to the elastic contraction of the spring member 6. At this time, the bent workpiece 9 will be ejected by the bending insert 2 (as shown in FIG. Figure 3 As shown), when the product is bonded to the mold, there is no need for workers to knock on the mold, the demoulding process is simple, and the demoulding efficiency is high.

[0016] See also Figure 2 The limiting component 7 includes a connecting column 71, a threaded sleeve 72 and a limiting threaded rod 73. The connecting column 71 is installed together with the limiting threaded rod 73 through the threaded sleeve 72. Only by unscrewing the threaded sleeve 72 from the connecting column 71, the spring component 6 can be removed and replaced.
