Description

Technical Field

[0001] This utility model relates to the field of bolt production equipment technology, specifically to a plow-shaped bolt production mold. Background Technology

[0002] Plowshare bolts consist of a shank, an end, and a square section between the transition shank and the end. Existing plowshare bolt production mostly uses hot forging, which is easy to form, but can lead to cracks due to abnormal internal structure of the blank. Cold heading is also used in existing production techniques, but the mold structure for cold heading is fixed, and the difficulty in adjusting the mold when changing it results in low production efficiency. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of the aforementioned background technology by providing a high-efficiency production mold for plow-shaped bolts.

[0004] To achieve the above objectives, this utility model provides a plow-shaped bolt production mold, which adopts the following technical solution:

[0005] A plow-shaped bolt production mold includes a first mold group and a second mold group. The first mold group includes a first die cavity and a first punch. The first die cavity has a first mold core and a second mold core, which cooperate to produce a stepped bolt. The first die cavity also has a first ejector pin that extends into the second mold core. The first die cavity also has a first adjusting mold core, which is located on the side of the first mold core away from the second mold core and is flush with the first die cavity. The second mold group includes a second die cavity and a second punch. The structure of the second die cavity is the same as that of the first die cavity. The second die cavity has a third mold core, a fourth mold core, and a second adjusting mold core. The third mold core is the same as the first mold core, and the fourth mold core is the same as the second mold core. The third mold core is flush with the second die cavity. The second die cavity has a second ejector pin that passes through the second adjusting mold core and extends into the fourth mold core.

[0006] A further improvement of this utility model for a plow-shaped bolt production mold is that a pad block is provided inside the first punch, and a third ejector pin is provided at one end of the pad block near the first die cavity. The third ejector pin passes through the first punch and extends into the first adjusting die core to limit the blank.

[0007] A further improvement of this utility model for a plow-shaped bolt production mold is that a fixed mold is provided between the second punch and the second die, and a fixed mold core is provided inside the fixed mold. The fixed mold core is used to limit the blank to form the square part and the end.

[0008] A further improvement of this utility model regarding a plow-shaped bolt production mold is that the number of the first adjusting mold core and the second adjusting mold core is adjustable.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] This invention improves production efficiency by setting up two sets of molds to ensure stable feeding when the blank moves. Attached Figure Description

Detailed Implementation

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] like Figure 1 As shown, a plow-shaped bolt production mold includes a first mold group 1 and a second mold group 2. The first mold group includes a first die 4 and a first punch 3. The first die has a first core 5 and a second core 6 inside. The first core and the second core cooperate to produce a stepped bolt rod. The first die also has a first ejector pin 7 inside, which extends into the second core. The first die also has a first adjusting core 8 inside, which is located on the side of the first core away from the second core and is flush with the first die. The second mold group includes a second die 12 and a second punch 11. The structure of the second die is the same as that of the first die. The second die has a third core 13, a fourth core 14, and a second adjusting core inside. The third core is the same as the first core, and the fourth core is the same as the second core. The third core is flush with the second die. The second die has a second ejector pin 16 inside, which passes through the second adjusting core and extends into the fourth core.

[0015] The first die is provided with a pad block 9. A third ejector pin 10 is provided at one end of the pad block near the first die cavity. The third ejector pin passes through the first die and extends into the first adjusting die core to limit the blank.

[0016] A fixed die 17 is provided between the second die and the second die cavity. A fixed die core 18 is provided inside the fixed die. The fixed die core is used to limit the blank to form the square part and the end.

[0017] The number of the first and second adjusting mold cores mentioned above is adjustable.

[0018] The working principle of this utility model is as follows: According to the specifications of the plow-shaped bolts with steps to be produced, a suitable mold core is selected, and a second mold core and a first mold core are set up. Then, a first adjusting mold core is set up, and the number is selected according to the actual situation. Then, the blank is set up, and the first punch works. At this time, a second adjusting mold core, a fourth mold core, and a third mold core are set up in the second cavity. The width of the second adjusting mold core is the same as the width of the first adjusting mold core, so as to ensure that the third mold core is flush with the second groove. At the same time, a fixed mold is set up. Then, the blank after the first punch is directly transferred to the second cavity, and the second punch works, which improves the production efficiency.

[0019] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
