Description

Technical Field

[0001] The present application relates to the technical field of mold stripping mechanisms, and in particular to a mold delayed stripping mechanism. Background Art

[0002] Molds are various molds and tools used in industrial production to obtain the desired products by injection molding, blow molding, extrusion, die casting or forging, smelting, stamping and other methods. Molds are tools used to make molded objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the object by changing the physical state of the molded material. It is known as the "mother of industry". The mold has a specific contour or inner cavity shape. The use of contour shapes with cutting edges can make the blanks separate (punch out) according to the contour shape. The use of inner cavity shapes can make the blanks obtain the corresponding three-dimensional shape. The mold generally includes a movable mold and a fixed mold (or a convex mold and a concave mold). The two parts can be separated or combined. When separated, the workpiece is taken out, and when closed, the blank is injected into the mold cavity for forming.

[0003] The existing patent (publication number: CN206455986U) discloses a delayed stripping mechanism, including a mold base, a bottom block is arranged above the mold base, and a movable clamping block is arranged on one side of the mold base, a first nitrogen device is arranged on one side of the bottom block, a stripping plate is arranged on the first nitrogen device and the top of the bottom block, a stripping ejector rod is arranged on the stripping plate, a second nitrogen device is arranged at the bottom of the movable clamping block, and an movable clamping block is arranged at a position parallel to the stripping plate clamping position on the movable clamping block.

[0004] The above-mentioned comparative document points out that when the upper and lower molds are separated, the stripper plate of the utility model cannot move upward temporarily, and the stripper plate starts to move upward only when the reset hook completely hooks the block out of the stripper plate. Thus, the effect of delayed stripping is achieved, the high delay nitrogen cost is saved, and the production cost of auto parts can be greatly reduced. At the same time, the stability of the stripper plate during demoulding is improved. The overall structure is simple and convenient for large-scale production. However, the device is highly dependent on the nitrogen device. If the nitrogen device fails or the nitrogen supply is insufficient, it may affect the normal operation of the mechanism. In addition, the risk factor of nitrogen requires some safety equipment, which increases the cost. Utility Model Content

At this time, the electric push rod is started to drive the fixed clamp to clamp the mold set on the punch head. When the clamping is completed, the hydraulic rod continues to retract. At this time, the fixed clamp will remove and fix the mold set. The motor is started to drive the threaded rod to work, and the slider will drive the electric push rod to move, thereby driving the fixed clamp to move.

[0008] Furthermore, connecting plates are fixedly connected to both sides of the lower base plate and the upper base plate.

[0010] Furthermore, a base corresponding to the punching head is fixedly connected to the upper end of the lower base plate.

[0011] Through the above scheme, the mold is punched by arranging the base to cooperate with the punching head.

[0012] Furthermore, an air pump is fixedly connected to one side of the lower base plate.
