Abstract
The utility model relates to a screw die convenient for demolding, which comprises an upper die and a lower die, wherein a forming cavity used for being matched with the upper die is arranged in the lower die, a feeding ring is connected below the lower die, a feeding hole used for being connected with the forming cavity is arranged in the feeding ring, a cutting gap is arranged between the lower die and the feeding ring, a bearing cutter is arranged in the cutting gap, when the screw die is used, external linear materials enter the forming cavity from the feeding hole, after the screw die reaches a preset length, the bearing cutter cuts off the linear materials and stays at the lower end of the feeding hole, then the upper die applies pressure to the forming cavity, so that the linear materials can be extruded into screw shapes, at the moment, the bearing cutter is reset, and when the subsequent linear materials enter the forming cavity, the formed screws are ejected out by the way, so that external equipment can take out the screws in batches, the operation is repeated, the screw production is performed, and the feeding and discharging efficiency is ensured.
Description
Technical Field
The utility model relates to the field of screw dies, in particular to a screw die convenient to demold.
Background
As a standard element for a fixed connection, screws are widely visible in modern production and life. The primary punch is used as one of cold forging dies necessary in the screw production industry, and is mainly used for pre-deforming materials, and the control accuracy of the dimension of the primary punch is required to meet the requirements in the screw production process. The existing die has lower discharging and feeding efficiency, so that a screw die convenient to demould is needed.
Disclosure of Invention
The utility model aims to solve the defects and provide a screw die convenient to demolding so as to solve the problems in the background art.
The object of the utility model is achieved by:
the screw die comprises an upper die and a lower die, wherein a forming cavity used for being matched with the upper die is arranged in the lower die, a feeding ring is connected to the lower portion of the lower die, a feeding hole used for being connected with the forming cavity is formed in the feeding ring, a cutting gap is formed between the lower die and the feeding ring, and a bearing cutting knife is arranged in the cutting gap.
In the above description, the lower end of the forming cavity is provided with a chamfer.
In the above description, the outer side of the lower die is wrapped with a fixing sleeve, and one side of the fixing sleeve is provided with a limiting guide groove for being matched with the bearing cutting knife.
In the above description, a plurality of fixing protrusions for being embedded in the fixing sleeve are arranged on the outer side of the lower die in a surrounding mode.
The utility model has the beneficial effects that: when the screw feeding device is used, external linear materials enter the forming cavity from the feeding hole, after the predetermined length is reached, the linear materials are cut off by the bearing cutting knife, the bearing cutting knife stays at the lower end of the feeding hole, then the upper die presses the forming cavity, so that the linear materials can be extruded into screw shapes, the bearing cutting knife is reset at the moment, the formed screws are ejected out by the way when the subsequent linear materials enter the forming cavity, so that the screws are taken out by external equipment, the operation is performed repeatedly, batch production of the screws is performed, and the feeding and discharging efficiency is guaranteed.

the reference numerals in the drawings are respectively: 1-upper die, 2-lower die, 201-forming cavity, 3-feeding ring, 301-feeding hole, 4-cutting gap, 5-fixing protrusion, 6-fixing sleeve, 601-limit guide slot and 7-bearing cutter.
Detailed Description
The utility model is described in further detail below with reference to the drawings and the detailed description.
Referring to fig. 1-3, a screw mold with convenient demolding is specifically implemented, the screw mold comprises an upper mold 1 and a lower mold 2, a forming cavity 201 for being matched with the upper mold 1 is arranged in the lower mold 2, a feeding ring 3 is connected below the lower mold 2, a feeding hole 301 for being connected with the forming cavity 201 is arranged in the feeding ring 3, a cutting gap 4 is arranged between the lower mold 2 and the feeding ring 3, and a bearing cutting knife 7 is arranged in the cutting gap 4.
The lower extreme of shaping die cavity 201 is equipped with the chamfer, and the outside parcel of lower mould 2 is provided with fixed cover 6, and one side of fixed cover 6 is provided with and is used for carrying on the spacing guide slot 601 of complex with bearing cutting knife 7, and the outside of lower mould 2 is encircleed and is provided with four fixed protruding 5 that are used for the gomphosis in fixed cover 6.
When in use, external linear materials enter the forming cavity 201 from the feeding hole 301 through an external feeding device, after the predetermined length is reached, the external cylinder drives the bearing cutter 7 to cut off the linear materials, the bearing cutter 7 stays at the lower end of the feeding hole 301, then the upper die 1 is driven by an external punching device to press the forming cavity 201, so that the linear materials can be extruded into screw shapes, at the moment, the bearing cutter 7 is reset, and the formed screws are ejected out when the subsequent linear materials enter the forming cavity 201, so that the external device can take out the screws, and the operation is repeated, so that batch production of the screws is performed, and the feeding and discharging efficiency is ensured.
The present utility model is not limited to the preferred embodiments, but is intended to be limited to the following description, and any modifications, equivalent changes and variations in light of the above-described embodiments will be apparent to those skilled in the art without departing from the scope of the present utility model.
