Description

Technical Field

[0001] This utility model relates to the field of molding die technology, and specifically to molding dies with guide structures. Background Technology

[0002] Existing forming dies are tooling fixtures that use external force to plastically deform metallic or non-metallic materials, thereby shaping them into target parts. They mainly consist of a punch, a die, and a support structure, and are widely used in stamping, drawing, and drop forming processes. Their core function is to achieve precise control of the part's shape and dimensions through the interaction between the die surface and the material. The forming of high-temperature alloy nozzle parts falls under the field of aerospace precision manufacturing. High-temperature alloys, due to their excellent high-temperature resistance and corrosion resistance, have become core materials for components used in extreme environments such as nozzles.

[0003] During the design process of this utility model, the following problems were found in the existing technology: Existing molding molds often lack precise guiding structures, which can easily cause offset during mold closing, resulting in insufficient part precision and mold wear. Furthermore, the sheet metal deforms unevenly during molding, which can easily lead to stress concentration and cracking. At the same time, the molds are heavy, making them inconvenient to handle and install, and they also have high equipment load, resulting in significant energy consumption and operational risks. Utility Model Content

[0004] The purpose of this invention is to provide a molding die with a guiding structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a molding die with a guiding structure, including an upper template, the bottom of which is screwed to the top of the upper die, and a lower die is provided at the bottom of the upper die;

[0006] The upper mold has guide plates on both its left and right outer walls; the upper mold has a pressure groove at its bottom.

[0007] The lower mold has guide grooves on both the left and right outer walls.

[0008] The beneficial effects of this utility model are as follows: the design of the upper template and the corresponding screw holes of the upper mold can realize quick and accurate assembly, enhance the firmness and facilitate disassembly and maintenance. The T-shaped guide plate inserted into the guide groove can limit the lateral displacement of the upper mold and automatically align itself, thereby ensuring the forming accuracy of the parts and the life of the mold. The curved surfaces of the pressure groove and the lower mold fit the contour of the parts, which can guide the sheet metal to deform evenly, reduce cracking and ensure shape accuracy. At the same time, the design of the weight reduction groove of the upper mold can reduce weight and equipment load by removing non-critical materials, improve operational safety and forming stability, and optimize material utilization and functional balance.

[0009] To achieve a quick and precise connection between the upper template and the upper mold using screw holes and bolts, ensuring alignment during installation, improving assembly efficiency, and facilitating disassembly and maintenance:

[0010] The upper template and the upper mold are further configured such that the contact surfaces of both are provided with a number of screw holes of the same number and in corresponding positions.

[0011] By adopting the above technical solution, the upper template and the upper mold have the same number of screw holes in corresponding positions on their contact surfaces. The two can be quickly and accurately connected by bolts, ensuring that the positions are aligned during installation, improving assembly efficiency, enhancing connection firmness, and facilitating disassembly and maintenance to meet the mold combination requirements of different forming stages.

[0012] To effectively limit the lateral displacement of the upper mold during mold closing, achieve high-precision automatic alignment of the upper and lower molds, and avoid part forming dimensional errors or mold wear caused by positional deviations:

[0013] The configuration is further defined as follows: both guide plates are T-shaped, and the bottom ends of the two guide plates are vertically inserted into the inner walls of the guide grooves on both sides.

[0014] By adopting the above technical solution, the two guide plates are T-shaped and their bottom ends are vertically inserted into the inner wall of the guide groove. By utilizing the stability and guiding properties of the T-shaped structure, the lateral displacement of the upper mold can be effectively limited during the mold closing process, so as to achieve high-precision automatic alignment of the upper and lower molds, avoid part forming size errors or mold wear caused by position deviation, and ensure the forming accuracy of complex curved parts and the service life of the mold.

[0015] To ensure that the contact surfaces of the groove and the lower die can precisely match the complex curved contours of the high-temperature alloy tail nozzle parts, guide uniform deformation of the sheet metal, and reduce the risk of material cracking caused by stress concentration:

[0016] A further setting is made: the contact surface between the pressure groove and the lower mold is set as a curved surface.

[0017] By adopting the above technical solution, the contact surfaces of the pressure groove and the lower mold are set as curved surfaces, which can be precisely matched with the complex curved surface contour of the high-temperature alloy tail nozzle parts. Thus, in the pre-forming and final forming stages, the curved surface structure can guide the sheet metal to deform uniformly, so that the sheet metal gradually fits the mold surface, reducing the risk of material cracking caused by stress concentration.

[0018] To significantly reduce the weight of the upper mold while maintaining the overall strength and heat resistance of the mold, making mold hoisting and handling more convenient, while reducing the load and energy consumption of the drop forming equipment, and improving operational safety and stability:

[0019] The upper mold is further configured such that a plurality of weight-reducing grooves are provided on one side of its outer wall, and the plurality of weight-reducing grooves are cast according to digital molds.

[0020] By adopting the above technical solution, several weight-reducing grooves are cast on one side of the outer wall of the upper mold according to the digital model. Material in non-critical stress areas can be removed. Under the premise of maintaining the overall strength and heat resistance of the mold, the weight of the upper mold can be significantly reduced, making the mold hoisting and transportation more convenient. At the same time, the load and energy consumption of the drop forming equipment are reduced, and the inertial error of the equipment operation caused by the excessive weight of the mold is reduced, thereby improving the operational safety and the stability of the forming process.

[0021] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0027] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0028] Please see Figures 1 to 4 A molding die with a guide structure includes an upper template 1, the bottom of which is screwed to the top of an upper mold 2, and a lower mold 3 is provided at the bottom of the upper mold 2.

[0029] Guide plates 4 are provided on both the left and right outer walls of the upper mold 2; a pressure groove 5 is provided at the bottom of the upper mold 2;

[0030] Guide grooves 6 are provided on both the left and right outer walls of the lower mold 3.

[0031] In this embodiment, as Figure 1 and Figure 2 As shown, the contact surfaces of the upper template 1 and the upper mold 2 are each provided with a number of screw holes of the same number and corresponding positions.

[0032] In this embodiment, as Figure 1 and Figure 3As shown, both guide plates 4 are T-shaped, and the bottom ends of the two guide plates 4 are vertically inserted into the inner walls of the guide grooves 6 on both sides.

[0033] In this embodiment, as Figure 4 As shown, the contact surface between the pressure groove 5 and the lower mold 3 is set as a curved surface.

[0034] In this embodiment, as Figure 1 and Figure 4 As shown, a number of weight-reducing grooves 201 are provided on one side of the outer wall of the upper mold 2, and the number of weight-reducing grooves 201 are cast according to digital mold.

[0035] The working process of this molding die with a guiding structure is as follows:

[0036] When using the machine for the first time, the operator can first smoothly clamp the lower mold 3 in the designated position of the skin forming machine, and then use the chuck of the skin forming machine to accurately clamp the edge of the high-temperature alloy sheet. Then, start the equipment to make the chuck and the lower mold 3 move relative to each other. During this process, the sheet is gradually attached to the surface of the lower mold 3 with the curved structure under the action of tension. At this time, the curved contour of the lower mold 3 achieves the pre-forming of the sheet through this relative movement, so that the sheet initially has the approximate curved shape of the tail nozzle part.

[0037] After preforming is completed, the operator can first use bolts to fix the upper template 1 to the top of the upper mold 2 through the same number and corresponding screw holes on its contact surface with the upper mold 2, ensuring a firm connection. Then, the upper mold 2 with the upper template 1 assembled is hoisted to the upper platform of the drop forming equipment and is securely installed by the equipment's fixing device. At the same time, the lower mold 3 is removed from the skin stretching machine and placed on the lower platform of the drop forming equipment. The position is adjusted so that the lower mold 3 and the upper mold 2 are on the same vertical axis.

[0038] Subsequently, the operator can carefully place the semi-finished sheet material that has been preliminarily formed on the upper surface of the lower mold 3, align it with the preset position, and after preparation, the operator can start the drop forming equipment. At this time, the upper platform will drive the upper mold 2 to move downward at a uniform speed. During this process, the bottom ends of the guide plates 4 located on the outer walls of the left and right sides of the upper mold 2 will gradually move downward and approach the guide grooves 6 on the left and right sides of the lower mold 3. Since the guide plates 4 have a T-shaped structure, their bottom ends will vertically insert into the inner wall of the guide grooves 6 during the descent. Thus, through the precise cooperation of the two, the upper mold 2 and the lower mold 3 are accurately aligned, ensuring that there is no positional deviation during the mold closing process.

[0039] After the guide plate 4 is fully embedded in the guide groove 6, the upper mold 2 will continue to move downward. At this time, the curved surface of the pressure groove 5 opened at the bottom will gradually fit with the upper surface of the lower mold 3 and apply uniform pressure to the semi-finished sheet material placed between the two. Then, through the extrusion action of the curved surface structure, the semi-finished sheet material will be further plastically deformed and finally fit with the complex curved surface of the mold to complete the precise forming of the high-temperature alloy tail nozzle part.

[0040] Throughout the entire operation process, several weight-reducing grooves 201 cast in digital molds on one side of the outer wall of the upper mold 2 play an important role. By removing material from non-critical stress areas, they effectively reduce the weight of the upper mold 2 without affecting the overall strength of the mold, making the upper mold 2 more convenient to hoist, fix and move with the equipment, reducing the load on the equipment, and improving the safety and efficiency of the operation.
