Description

Technical Field

[0001] The invention relates to the technical field of molds, in particular to a screw mold. Background Art

[0002] Screw molds are special tools used to make screws. Through specific processes and structural designs, they can efficiently and accurately produce screws of various types and specifications. As a common fastener, screws are widely used in many fields such as machinery manufacturing, automobile manufacturing, electronic equipment, and construction industry.

[0003] Most of the hexagonal slots on the screws are formed by stamping, but the existing stamping dies are relatively simple, with only one stamping head. During automated production, once the screw is stuck on the stamping head and cannot be easily removed, the two screws will collide with each other during the subsequent automatic installation of the screws, thereby causing damage to the screw. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings in the prior art and to provide a screw mold.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions: A screw mold, comprising a mold installation column, a push block is movably arranged on the top of the mold installation column, a mounting cavity is opened inside the mold installation column, an inner core sleeve is arranged at the bottom of the mounting cavity, an inner core is movably arranged inside the inner core sleeve, a punch head mechanism is installed above the inner core sleeve in the mounting cavity, a plurality of push rods are evenly arranged and vertically movably arranged on the punch head mechanism, and the tops of the push rods are all mounted on the push block; A third through hole is opened in the middle of the push block, and a plurality of fourth through holes are opened evenly arranged around the third through hole. The top of the push rod is installed at the fourth through hole, and a first screw hole connected to the fourth through hole is opened on the side wall of the push block, and a fixing component for fixing the push rod is installed at the first screw hole.

[0006] In addition, a preferred structure is that a slot is provided in the middle of the side wall of the mold installation column, and a second through hole coaxial with the third through hole is provided in the middle of the top end of the mold installation column.

[0007] In addition, a preferred structure is that a plurality of first through holes coaxial with the fourth through hole are evenly arranged around the second through hole, and the push rod is movably arranged at the first through hole.

[0008] In addition, a preferred structure is that the push rod includes a first column at the bottom, a second column is fixedly connected to the top of the first column, a third column is fixedly connected to the top of the second column, and a second screw hole for installing the fixing component is opened on the side wall of the third column.

[0009] In addition, a preferred structure is that a cavity is vertically penetrated on the inner core sleeve, the inner core is arranged to slide in the cavity, and the inner core is used to push the push rod to move vertically.

[0010] In addition, a preferred structure is that the punch head mechanism includes a limit block, a hexagonal punch head is vertically arranged in the middle of the top surface of the limit block, and the hexagonal punch head is located at the second through hole and the third through hole.

[0011] In addition, a preferred structure is that the limit block is installed inside the installation cavity and located above the inner core sleeve, and a plurality of fifth through holes are evenly arranged around the hexagonal punching head on the limit block, and the push rod is arranged at the fifth through hole for vertical movement.

[0012] The beneficial effects of the present invention are as follows: in the present invention, after the equipment sends the screw to the hexagonal punching head for punching, the push rod drives the pushing block, so that the screw stuck on the hexagonal punching head can be effectively pushed out and dropped, thereby preventing the screw from being stuck on the hexagonal punching head and unable to be removed, thereby affecting subsequent punching, and preventing other screws from colliding with the stuck screw during subsequent punching. The present invention can effectively and automatically remove the stuck screw, and effectively improve the stamping efficiency of the mold. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] A slot 11 is provided in the middle of the side wall of the mold installation column 1 , and a second through hole 14 coaxial with the third through hole 21 is provided in the middle of the top of the mold installation column 1 . The slot 11 is used for installing the mold installation column 1 .

[0018] In addition, a plurality of first through holes 13 coaxial with the fourth through hole 22 are evenly arranged around the second through hole 14, and the push rod 7 is movably arranged at the first through hole 13. The push rod 7 includes a first column 71 at the bottom, a second column 72 is fixedly connected to the top of the first column 71, and a third column 73 is fixedly connected to the top of the second column 72. Second screw holes 74 for installing the fixing component 4 are provided on the side walls of the third column 73. The third column 72 is used to abut against the bottom of the limit block 32, and the second column 72 is convenient for abutting against the bottom of the push block 2.

[0019] At the same time, a cavity 51 is vertically penetrated on the inner core sleeve 5, and the inner core 6 is arranged to slide in the cavity 51. The inner core 6 is used to push the push rod 7 to move vertically. The inner core 6 is used to push the push rod 7 to move.

[0020] Moreover, the punching head mechanism 3 includes a limit block 32, and a hexagonal punching head 31 is vertically arranged in the middle of the top surface of the limit block 32. The hexagonal punching head 31 is located at the second through hole 14 and the third through hole 21.
