Description

Technical Field

[0001] The utility model relates to the field of gear processing equipment, in particular to a mold structure of a high-strength gear bracket. Background Art

[0002] Gear brackets are needed in the gear processing process. Gear brackets are mostly Figure 4 The structural form is similar to a disc structure with an axial opening;

[0003] The gear bracket requires a mold structure during the processing. The mold structure provided in the related art is mostly of this structure, including a movable upper mold and a lower mold fixed in the middle position inside the base. The lower mold and the upper mold are at the same horizontal height.

[0004] When using this die structure, the sheet material for stamping is placed on the upper surface of the lower die, and then the upper die is moved by the output kinetic energy of the hydraulic cylinder to move closer to the lower die to perform stamping and forming operations on the sheet material placed on the upper surface of the lower die.

[0005] During this stamping process, since the lower die is fixed in the middle of the base, it will not move during the stamping process of the raw material sheet, thus ensuring the quality of the stamped product. However, there are also some defects. For example, the stamped product remains in the groove of the lower die and needs to be removed manually using tools. This not only increases the burden on the operator, but also reduces the processing efficiency of the entire stamping product.

[0006] In view of the problems in the above background technology, the present invention aims to provide a mold structure for a high-strength gear bracket. Utility Model Content

[0007] The purpose of the present invention is to provide a mold structure of a high-strength gear bracket to solve the problems raised in the above background technology.

[0008] To achieve the above objectives, the present invention provides the following technical solutions:

[0009] A mold structure for a high-strength gear bracket, comprising:

[0010] The upper die and the lower die are movably mounted above the lower die, an upper cavity is formed inside the upper die, and a punching assembly is movably mounted inside the upper cavity; the lower die is mounted on the base, and a stamping assembly is movably mounted inside the lower die.

[0011] As a further solution of the present invention: the lower mold is T-shaped, and blocks are symmetrically installed on both sides of the lower mold; card slots are symmetrically distributed inside the middle of the base; the card blocks arranged on both sides of the lower mold are inserted into the card slots opened inside the middle of the base.

[0012] As a further solution of the present invention: the punching assembly includes a protrusion, an upper push rod and an upper rod end; the protrusion is slidably installed inside the upper cavity, and an upper push rod is provided in the middle of the upper end of the protrusion; the end part of the upper end of the upper push rod after passing through the upper cavity is provided with an upper rod end, and the upper rod end is connected to the hydraulic rod; at the same time, an upper compression spring is mounted on the part of the upper push rod inside the upper cavity.

[0013] As a further solution of the present invention: the stamping assembly includes a T-die, a push column, a slide plate and a hydraulic push rod. The T-die is movably installed inside the lower die, and a cavity is formed at the axial center position of the T-die. A push column is movably installed inside the cavity; the lower end of the push column is fixed on the slide plate, and the slide plate is slidably installed inside the movable groove opened in the base, and the middle lower end of the slide plate is connected to the gear bracket.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] Compared with the current mold structure, the mold structure of the high-strength gear bracket has the following advantages:

[0016] The original mold structure only has the defect of the upper mold moving in one direction. The innovative design is to install a punching component inside the upper mold and a stamping component inside the lower mold. When the upper mold and the lower mold move relative to each other at the same time, the raw material sheet is punched by the punching component, and the installed stamping component performs the stamping and forming operation on the sheet.

[0017] This can not only ensure the quality of the stamped products (the strain shaping of the sheet metal by stamping from top and bottom at the same time has better shaping quality than the one-way stamping products), but also push the stamped products out in the later stage without the need for manual tools to pick them up, which greatly improves the processing efficiency of the mold.
