Description

Technical Field

[0001] This utility model relates to the field of steel structure parts production technology, specifically a molding die for the production of steel structure parts. Background Technology

[0002] Steel structure parts production refers to the process of processing steel into components or parts that meet the needs of construction, bridges, machinery and other fields through a series of processes. The production process must take into account precision, strength and economy. Steel structure parts production includes raw material cutting, parts processing, welding and assembly, surface treatment, quality inspection and acceptance and other processes. Parts processing includes forming processing, hole processing and edge treatment. Forming processing is to process parts into shape by stamping, bending and other methods. Hole processing is to use a drilling machine to open holes in the formed parts. Edge treatment is to chamfer or mill the edges of the cut parts, which may have burrs and oxide scale, to ensure welding quality.

[0003] In current technologies, the forming process for producing steel structure parts requires the use of stamping equipment and forming dies to stamp the parts into the shape of the drawings. The forming die mainly consists of upper and lower dies, die base, and die core. In actual working conditions, after the steel structure part is stamped, it gets stuck inside the lower die, requiring workers to lift it. However, the outer surface of the steel structure part is in close contact with the inner wall of the die, which can easily cause scratches on the outer surface of the part. Moreover, demolding is difficult. Therefore, a forming die for the production of steel structure parts is proposed to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a forming mold for the production of steel structure parts. It has the advantages of protecting the surface of the parts and automatic demolding. It solves the problem that in actual working conditions, after the steel structure parts are stamped, they get stuck inside the lower mold and require workers to lift them up. However, the outer surface of the steel structure parts is in close contact with the inner wall of the mold, which can easily cause scratches on the outer surface of the parts. Moreover, demolding is difficult.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a forming mold for producing steel structure parts, comprising a mold base and a mold core, wherein two side molds are provided on the mold base, and each of the two side molds is provided with a demolding structure;

[0006] The demolding structure includes two ejector components for ejecting steel structural parts. The ejector components are mounted on the side mold. A guide platform for extruding the ejector components is fixedly mounted on the mold base. An electric push rod with a telescopic end fixedly connected to the side mold is fixedly mounted on the mold base.

[0007] The ejector includes a top plate installed inside the side mold, and the top plate is used to eject and support parts. Two connecting rods that penetrate the side mold are fixedly installed at the bottom of the top plate. A trapezoidal plate is fixedly connected to the ends of the two connecting rods. A telescopic spring for supporting the trapezoidal plate is sleeved on the outer surface of the two connecting rods, and the telescopic spring is located at the top of the trapezoidal plate.

[0008] Furthermore, the side mold has a mating hole, and a pin adapted to the mating hole is fixedly installed on the side mold. The side mold has two rectangular grooves adapted to the top plate, and the inner bottom wall of the rectangular groove has two through holes penetrating the side mold, and the through holes are slidably connected to the connecting rod.

[0009] Furthermore, a guide groove is provided at the bottom of the side mold, and two guide ridges are fixedly installed on the mold base, with the inner wall of the guide groove slidably connected to the guide ridges.

[0010] Furthermore, the inclined surface of the trapezoidal plate contacts the inclined surface of the guide platform, and the inclined surface of the guide platform on the same side has the same slope as the inclined surface of the trapezoidal plate.

[0011] Furthermore, the side mold has several vent holes, the side mold has a meshing groove that matches the mold core, and the mold base has two wiring holes.

[0012] Furthermore, the two side molds are slidably mounted on the mold base and are centrally symmetrically distributed. The mold core is fixedly mounted on the mold base and is adapted to the meshing grooves on the two side molds.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] This forming mold for steel structure parts production features a demolding structure that, through the cooperation of the guide table and the inclined trapezoidal plate, converts the horizontal movement of the side mold into the vertical movement of the top plate. Demolding is completed simultaneously during the opening of the side mold, greatly improving demolding efficiency. Moreover, the top plate acts directly on the surface of the part, resulting in uniform ejection force, which effectively prevents deformation or damage to the part due to excessive local stress, ensuring part quality. The venting holes on the side mold allow gas to be discharged during the forming process, preventing defects such as porosity and improving the forming quality of the part. Furthermore, the sliding connection between the guide groove and the guide table, as well as the cooperation between the mating hole and the pin, ensure the stability and accuracy of the side mold movement, extending the mold's service life.

[0022] 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.

[0023] Example 1: Please refer to Figure 1-6 In this embodiment, a forming mold for producing steel structure parts includes a mold base 1 and a mold core 3. The mold base 1 is provided with two side molds 2, and each of the two side molds 2 is provided with a demolding structure 4. The two side molds 2 are slidably installed on the mold base 1 and are centrally symmetrically distributed. The mold core 3 is fixedly installed on the mold base 1 and is adapted to the meshing grooves on the two side molds 2.

[0024] Example 2: Please refer to Figure 1-6 Based on Embodiment 1, the demolding structure 4 includes two ejector parts 41 for ejecting steel structure parts. The ejector parts 41 are installed on the side mold 2. A guide platform 42 for extruding the ejector parts 41 is fixedly installed on the mold base 1. An electric push rod 43 with its telescopic end fixedly connected to the side mold 2 is fixedly installed on the mold base 1.

[0025] The ejector 41 includes a top plate 411 installed inside the side mold 2. The top plate 411 is used to eject and support the part. Two connecting rods 412 that penetrate the side mold 2 are fixedly installed at the bottom of the top plate 411. A trapezoidal plate 413 is fixedly connected to the ends of the two connecting rods 412. A telescopic spring 414 for supporting the trapezoidal plate 413 is sleeved on the outer surface of the two connecting rods 412. The telescopic spring 414 is located at the top of the trapezoidal plate 413. The top plate 411 acts directly on the surface of the part, and the ejection force is uniform. This can effectively prevent the part from deforming or being damaged due to excessive local force, thus ensuring the quality of the part.

[0026] The inclined surface of the trapezoidal plate 413 contacts the inclined surface of the guide platform 42, and the inclined surface of the guide platform 42 on the same side has the same slope as the inclined surface of the trapezoidal plate 413. With the cooperation of the inclined surfaces of the guide platform 42 and the trapezoidal plate 413, the horizontal movement of the side mold 2 is converted into the vertical movement of the top plate 411. Demolding is completed simultaneously during the opening of the side mold 2, which greatly improves the demolding efficiency.

[0027] In addition, the side mold 2 has several vent holes and a meshing groove that matches the mold core 3. The mold base 1 has two wiring holes. The vent holes on the side mold 2 can discharge gas during the molding process, prevent defects such as air holes in the parts, and improve the molding quality of the parts.

[0028] Using the above technical solution, the electric push rod 43 pulls the side mold 2 away from the mold core 3 along the guide ridge 11. During the movement, the inclined surface of the trapezoidal plate 413 interacts with the inclined surface of the guide table 42, causing the trapezoidal plate 413 to move upward. Through the connecting rod 412, the top plate 411 is pushed out of the rectangular groove 24, thereby pushing the part out of the side mold 2 and realizing demolding.

[0029] Example 3: Please refer to Figure 1-6 Based on Embodiment 2, the side mold 2 is provided with a docking hole 22, and a pin 23 adapted to the docking hole 22 is fixedly installed on the side mold 2. The side mold 2 is provided with two rectangular grooves 24 adapted to the top plate 411 respectively. The inner bottom wall of the rectangular groove 24 is provided with two through holes 25 penetrating the side mold 2, and the through holes 25 are slidably connected to the connecting rod 412.

[0030] The side mold 2 has a guide groove 21 at its bottom, and two guide ridges 11 are fixedly installed on the mold base 1. The inner wall of the guide groove 21 is slidably connected to the guide ridges 11. The slidable connection between the guide groove 21 and the guide ridges 11, as well as the cooperation between the mating hole 22 and the pin 23, ensure the stability and accuracy of the movement of the side mold 2 and improve the service life of the mold.

[0031] Using the above technical solution, during mold closing, the electric push rod 43 pushes the side mold 2 to move along the guide ridge 11 towards the mold core 3 until the two side molds 2 are closed. At this time, the mating hole 22 on the side mold 2 cooperates with the pin 23 to ensure the accurate position of the side mold 2. At the same time, the trapezoidal plate 413 is tightly fitted with the guide table 42 under the action of the telescopic spring 414, and the top plate 411 is located in the rectangular groove 24, forming a complete molding cavity together with the side mold 2 and the mold core 3.

[0032] The working principle of the above embodiments is as follows:

[0033] When the mold for producing steel structure parts is closed, the electric push rod 43 pushes the side mold 2 to move along the guide ridge 11 toward the mold core 3 until the two side molds 2 are closed. At this time, the mating hole 22 on the side mold 2 cooperates with the pin 23 to ensure the accurate position of the side mold 2. At the same time, the trapezoidal plate 413 is tightly fitted with the guide table 42 under the action of the telescopic spring 414. The top plate 411 is located in the rectangular groove 24, and together with the side mold 2 and the mold core 3, it forms a complete forming cavity.

[0034] In the forming process, steel is placed into the forming cavity formed by the mold core 3 and the side mold 2. The upper mold is controlled to move downward by the stamping equipment. The part is stamped and formed by the interaction of the upper mold, the side mold 2 and the mold core 3.

[0035] During the demolding process, the electric push rod 43 pulls the side mold 2 away from the mold core 3 along the guide ridge 11. During the movement, the inclined surface of the trapezoidal plate 413 interacts with the inclined surface of the guide table 42, causing the trapezoidal plate 413 to move upward. Through the connecting rod 412, the top plate 411 is pushed out of the rectangular groove 24, thereby pushing the part out of the side mold 2 and realizing demolding.
