Description

Technical Field

[0001] The utility model relates to the technical field of mold design and manufacturing, in particular to a floating block structure of a high-strength mechanical mold. Background Art

[0002] With the rapid development of the new energy vehicle market, the speed of vehicle model updates and iterations has increased significantly, resulting in more frequent product upgrades for automotive stamping parts. The mold structure is also being improved. The floating block is a very common mold part in the hardware and automobile mold structure. Its function is to lift the workpiece or the process material belt to ensure that the mold can feed forward smoothly. Figure 1 As shown, in the limited mold space, floating blocks in the form of hanging tables are often chosen. The material of the floating blocks is generally made of alloy tool sodium CR12 (hardness is HRC50~HRC53); CR12 steel is a widely used cold working die steel with high strength, good hardenability and good wear resistance, but poor impact toughness. During mold trial and mass production, there is a situation where the floating block hanging table has to withstand the impact force of the spring, and the floating block is easy to break. On the one hand, it reduces the stability and production efficiency of the production process and increases the scrap rate of parts. On the other hand, the broken floating block will fall onto other mold parts, causing the mold to explode, increasing the number of mold repairs and production downtime.

[0003] During mass production, the high speed of the mechanical die punching machine causes a sharp increase in the tensile force on the floating block hanger, causing it to break. Under the influence of elastic inertia, the hanger is prone to early metal fatigue under large-scale production conditions, and when it reaches its peak, it breaks, posing a serious safety hazard to production.

[0004] The utility model provides a floating block structure for a high-strength mechanical mold. By modifying the floating block into two parts, the main guide part adopts CR12 (HRC50~HRC53) wear-resistant steel, and the split and hanging platform parts adopt impact-resistant 45# steel. This solves the problem of the floating block and hanging platform breaking, reduces the maintenance cost of the mechanical mold, ensures the smooth mass production of parts during application, and improves the processing quality.

[0005] In order to solve the above problems, the utility model provides a floating block structure for a high-strength mechanical mold, including a floating block, wherein the floating block is provided with a main body and a split body, the main body and the split body are fixedly connected, and hanging platforms are provided on both sides of the split body, the main body is alloy tool steel, and the split body is high-quality carbon steel, the hanging platform is fixed to the bottom of the lower mold of the mold, and the split body is connected to a floating spring.

[0006] Preferably, the main body and the sub-body are fixedly connected by screws.

[0007] The main body and the split body are fixedly connected by screws to form a floating block as a whole, which plays a role in bearing the force of different parts of the floating block.

[0008] Preferably, the main body is made of Cr12 alloy tool steel.

[0009] The main body is Cr12 alloy tool steel, which has the characteristics of high strength, good hardenability and good wear resistance, but poor impact toughness, so the top of the floating block is specifically wear-resistant.

[0010] Preferably, the split body is made of 45# high-quality carbon steel.

[0011] The split part is made of 45# high-quality carbon steel, which is impact-resistant and not easy to break under the impact of the mold spring.

[0013] Preferably, the split body is detachable.

[0014] The two parts are detachable, making it easy to replace and repair damaged main body and two parts.

[0015] Preferably, the spring is located in the spring holes of the lower plate and the lower die base.

[0016] The spring is located in the spring holes of the lower pad and the lower die seat to achieve the elastic floating requirements of the floating block of the mold.

[0017] Preferably, one end of the spring abuts against the split body of the floating block, and the other end is fixed by a set screw.

[0018] The beneficial effects of the utility model are as follows: the traditional integral floating block is changed into a main body and a split structure of different hardness and elastic materials, the main body and the split are fixedly connected, the main body is alloy tool steel CR12, which has good wear resistance, but poor impact toughness, so the hanging platform split of the floating block is made of conventional 45# steel for impact resistance to adapt to the wear resistance of the upper part of the floating block, the split hanging platform is impact-resistant, the floating block is not easy to break, and can be replaced and repaired separately, with the following advantages:

[0028] In order to more fully understand the technical content of the present invention, the technical solution of the present invention is further introduced and illustrated below in conjunction with the accompanying drawings and specific embodiments, but is not limited thereto.

[0029] like Figures 1 to 4 As shown, a specific embodiment of the utility model is a floating block structure of a high-strength mechanical mold, including a floating block. The floating block is provided with a main body 1 and a split 2. The main body 1 and the split 2 are fixedly connected. Hanging platforms 3 are provided on both sides of the split 2. The main body 1 is alloy tool steel, and the split 2 is high-quality carbon steel. The hanging platform 3 is fixed to the bottom of the lower mold of the mold, and the split 2 is connected to the floating spring 6.

[0030] Furthermore, the main body 1 and the split body 2 are fixedly connected by screws.

[0031] The main body 1 and the split body 2 are fixedly connected by screws to form a floating block as a whole, which plays a role in bearing the force of different parts of the floating block.

[0032] Furthermore, the main body 1 is made of Cr12 alloy tool steel.

[0033] The main body 1 is made of Cr12 alloy tool steel, which has the characteristics of high strength, good hardenability and good wear resistance, but poor impact toughness, so the top of the floating block is particularly wear-resistant.

[0042] Conventional floats are made of CR12 with a hardness of 50-53 degrees. The hanging platform 3 is affected by the inertia of the elastic pressure. Under mass production conditions, metal fatigue is likely to occur earlier and break when it reaches the extreme, causing great harm to production safety.

[0043] The integral structure of the hanging platform 3 is changed to a split 2 structure, and the material of the load-bearing part of the hanging platform 3 is changed to 45# steel, which increases its plasticity and toughness, has strong impact resistance, is not prone to metal fatigue, and greatly increases production safety.

[0044] The mold also includes a lower mold plate 4, a lower pad 5, a spring 6, a set screw 7 and a lower mold base 8.

[0045] The beneficial effects of the present invention are as follows: the traditional integral floating block is changed into a main body 1 and a split 2 structure of different hardness and elastic materials, the main body 1 and the split 2 are fixedly connected, the main body 1 is alloy tool steel CR12, which has good wear resistance, but poor impact toughness, so the hanging platform 3 and the split 2 of the floating block are made of conventional 45# steel for impact resistance to adapt to the wear resistance of the upper part of the floating block, the hanging platform 3 of the split 2 is impact-resistant, the floating block is not easy to break, and can be replaced and repaired separately, with the following advantages:
