Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a mold hard guide structure. Background Art

[0002] The processing technology of TV back panels involves multiple links, including material selection, design, cutting, stamping, grinding, spraying and other steps; the specific processing technology may vary according to the different materials, and the general process is as follows: select suitable materials according to design requirements, commonly used materials include metal, plastic, fiberglass, etc.; design CAD drawings according to the functions and appearance requirements of the TV back panel; use laser cutting machines, CNC cutting machines and other equipment to cut the materials to obtain the required shape of the back panel; shape the cut materials, which can be done by stamping, bending, die-casting and other processes; grind the formed back panel to make the surface smooth and burr-free; spray according to design requirements to increase the appearance and protection performance of the back panel; conduct quality inspection on the processed TV back panel to ensure that it meets the requirements.

[0003] The existing stamping die generally adopts the cooperation of the upper die seat and the lower die seat, and the workpiece is placed on the upper die seat and the lower die seat for stamping and forming. For example, Chinese patent announcement number CN204735602U discloses "a TV back panel stamping die", which includes an upper die seat, a lower die seat, an upper template, a lower template, a punch rod and a bushing. The upper die seat and the lower die seat are arranged symmetrically up and down, and the lower end surface of the upper die seat is connected to the upper template, and a stop plate is provided under the lower template. During the closing process of the mold, the bud is pre-punched, and after punching through, the waste falls from the bushing. At the same time, the bushing sinks downward through the compression spring to complete the flanging of the bud hole, so as to achieve one-time budding without skipping waste, which not only saves the bud pre-punching process, but also overcomes the problem of one-time budding and skipping waste.

[0004] However, in actual use, when stamping the back panel of a TV, due to the existence of arc-shaped structures, the direction of the reaction force exerted on the mold by the workpiece is also different. The lateral force is too large, and the mold is easily offset after being subjected to the force, affecting the accuracy. Utility Model Content

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] Embodiment 1:

[0027] Reference Figure 1-6 A mold hard guide structure includes a lower mold base 1, an upper mold base 2 and a workpiece 3, the workpiece 3 is arranged between the lower mold base 1 and the upper mold base 2, and hard guide components 4 are arranged on the lower mold base 1 and the upper mold base 2, and the two hard guide components 4 are arranged oppositely;

[0028] The hard guide assembly 4 includes a mounting seat 41 connected to the lower die seat 1 or the upper die seat 2 and a wear block 42. The mounting seat 41 is provided with a mounting groove 43. The wear block 42 is detachably arranged in the mounting groove 43. The wear blocks 42 of the two hard guide assemblies 4 are arranged opposite to each other.

[0029] In the utility model, the hard guide components 4 cooperate with each other to resist the lateral force of the mold. During this process, the two wear-resistant blocks 42 squeeze each other to provide support for the mold, prevent the upper mold base 2 and the lower mold base 1 from being misaligned after being subjected to force, and reduce the impact on the upper mold base 2 and the lower mold base 1. The wear-resistant block 42 is detachably connected to the mounting seat 41. When the wear-resistant block 42 is damaged, it can be replaced in time to avoid affecting the use of the mold.

[0030] Furthermore, in the present embodiment, a connecting portion 44 is fixedly provided on the wear-resistant block 42, a connecting groove matching with the connecting portion 44 is provided on the mounting seat 41, a plug-in portion 45 is fixedly provided on one side of the connecting portion 44, and a slot matching with the plug-in portion 45 is provided on the mounting seat 41. The connecting portion 44 and the wear-resistant block 42 are preliminarily fixed by the cooperation between the slot and the plug-in portion 45 to limit the position of the wear-resistant block 42.

[0031] Furthermore, in the present embodiment, a guide groove is provided on the wear-resistant block 42, a guide column 46 is slidably arranged in the guide groove, a slide groove matching the guide groove is provided on the plug-in portion 45, a limit block 47 is slidably arranged in the slide groove, and a limit groove corresponding to the limit block 47 is provided on the slot. By setting the limit groove and engaging with the limit block 47, the position of the plug-in portion 45 is fixed to prevent it from being driven and separated from the slot, thereby effectively preventing the wear-resistant block from falling off.

[0032] It should be noted that, in the present embodiment, a driving block 461 is fixedly provided at the lower end of the guide column 46, a driving groove matching with the driving block 461 is provided in the guide groove, and a first spring 462 is provided between the driving groove and the driving block 461.

[0034] In detail, in some embodiments, a slope 471 is provided at the lower end of the limit block 47. When the wear-resistant block 42 is installed, the slope of the limit block 47 abuts against the slot, forcing the limit block 47 to move backward into the slide groove, making it easier to insert the plug-in part 45 into the slot.

[0035] Working method: When working, the two wear-resistant blocks 42 squeeze each other to provide support for the mold, prevent the upper mold base 2 and the lower mold base 1 from being misaligned after being subjected to force, and reduce the impact on the upper mold base 2 and the lower mold base 1. The wear-resistant block 42 is detachably connected to the mounting seat 41. When the wear-resistant block 42 is damaged, it can be replaced in time to avoid affecting the use of the mold. By pressing the guide column 46, the limit block 47 is driven to move and separate from the limit groove. Under the action of the second spring 48 and the push plate 49, the plug-in part 45 is auxiliary pushed to facilitate the removal of the wear-resistant block 42 for replacement.
