Technical Field

[0001] The utility model relates to the technical field of automobile parts production and processing, in particular to a glass lifter processing mould. Background Art

[0002] The glass lifter can control the lifting and lowering of the car window glass. The glass lifter can be made through a stamping process, and a mold is required for stamping.

[0003] After searching, the application with patent number CN215745915U discloses a stamping die for automobile glass lifter with automatic demoulding function, which includes a base, a supporting plate is fixedly installed on the top of the base, and a concave die is fixedly connected to the top of the supporting plate, a plurality of positioning columns distributed in an array are fixedly installed on the top of the base, and a stamping plate is penetrated on the positioning columns, a hydraulic cylinder is fixedly connected to the top of the stamping plate, and a convex die is fixedly connected to the bottom of the stamping plate, and a demoulding mechanism is arranged between the base and the stamping plate;

[0004] Although the automobile glass lifter stamping die with automatic demoulding function is provided with a demoulding mechanism, when the stamping is completed, the hydraulic cylinder drives the stamping plate to lift, and drives the driving plate to move in opposite directions through the sleeve plate, the driving rod, and the sliding transmission, so that the driving plate cuts into and lifts the demoulding column at an angle, and the demoulding column ejects the stamping part, but the contact surface between the driving plate and the demoulding column of the automobile glass lifter stamping die with automatic demoulding function is repeatedly rubbed, which is easy to cause wear and has a short service life.

[0005] Therefore, we proposed a glass lifter processing mold. Utility Model Content

[0006] In view of the deficiencies of the prior art, the utility model provides a glass lifter processing mold, which solves the problem that the contact surface between the driving plate and the demoulding column of the prior device is repeatedly rubbed, easily wears out and has a short service life.

[0007] To achieve the above purpose, the utility model is implemented by the following technical solutions: a glass lifter processing mold includes a bottom plate, a concave mold is fixedly installed on the top surface of the bottom plate, and a convex mold is arranged just above the concave mold;

[0008] The top surface of the die is provided with a die cavity, the bottom surface of the die cavity is provided with symmetrically distributed bottom grooves, the side walls of the die cavity are provided with symmetrically distributed side grooves, the side grooves and the bottom grooves on the same side have the same width and form an "L"-shaped groove that is interconnected, and the convex mold is provided with an integrally formed "L"-shaped stripping plate, the stripping plate has the same width as the "L"-shaped groove and is positioned opposite to each other.

[0009] Preferably, symmetrically distributed slide grooves are provided through both sides of the top surface of the punch, the size of the slide grooves matches the stripping plate, and the stripping plate is slidably mounted inside the slide grooves, so that the stripping plate can slide inside the slide grooves.

[0010] Preferably, the length of the stripping plate is three times the length of the "L"-shaped groove, and a limiting plate is fixedly installed on the top surface of the stripping plate, wherein when the stripping plate is embedded in the "L"-shaped groove, a certain distance is created between the die and the punch, thereby facilitating the placement of the raw material into the mold cavity. The limiting plate can prevent the stripping plate from detaching from the inside of the slide groove.

[0011] Preferably, a model protrusion corresponding to and matching the mold cavity is fixedly mounted on the bottom surface of the male mold, wherein the model protrusion and the mold cavity are used in conjunction with each other to extrude the raw material inside the mold cavity.

[0012] Preferably, a U-shaped plate is fixedly installed on the top surface of the base plate, a hydraulic cylinder is fixedly installed in the middle of the top surface of the U-shaped plate, and the output end of the hydraulic cylinder passes through the top surface of the U-shaped plate and is fixedly installed on the top surface of the punch, wherein the hydraulic cylinder is used to drive the punch to move up and down, and then the stamping work is carried out.

[0013] The utility model provides a glass lifter processing mold, which has the following beneficial effects:

[0014] The glass lifter processing mold pushes the punch downwards by a hydraulic cylinder until the stripper plate is embedded in the "L"-shaped groove, and then the raw material is placed in the mold cavity, and the punch is pushed downwards continuously. In the process of the punch continuing to move downwards, the stripper plate can guide the punch to avoid the punch from shifting when it moves downwards, thereby improving the accuracy of the mold closing. After the raw material is stamped and formed, the punch is pulled upwards by a hydraulic cylinder. In the process of the punch moving upwards, the stripper plate is also pulled upwards due to the limiting effect of the limiting plate on the stripper plate, and then the stamping part formed in the mold cavity is hooked out by the stripper plate. Since the stripper plate is an integral structure, the stripper plate will not generate significant wear when moving, thereby increasing the service life of the stripper plate, and solving the problem of repeated friction between the contact surface of the driving plate and the stripper column of the existing device, which is prone to wear and has a short service life.

The side groove 22 and the bottom groove 23 on the same side have the same width and form an "L"-shaped groove that is interconnected. An integrally formed and "L"-shaped stripping plate 6 is arranged on the punch 3. The stripping plate 6 has the same width as the "L"-shaped groove and is opposite in position. Symmetrically distributed slide grooves 31 are opened on both sides of the top surface of the punch 3. The size of the slide groove 31 matches that of the stripping plate 6.
