Description
Technical Field
[0001] This utility model relates to the field of investment casting technology, and in particular to a shaping device and hydraulic shaping equipment for double-layer round-mouth products. Background Technology
[0002] In the field of investment casting, double-layered thin-walled round-mouth castings have always been a technical challenge due to their unique shape and complex manufacturing process. Investment casting, as a high-precision casting method, is widely used in aerospace, automotive, and medical fields, especially in applications requiring extremely high dimensional accuracy. In the investment casting process, the wax model, as the direct precursor to the final casting, directly affects the quality of the casting. This is particularly critical for thin-walled castings with double-sided round mouths. However, during the wax model stage, due to the inherent properties of the material and various factors during processing, the wax model is prone to deformation, directly affecting its roundness.
[0003] In the investment casting process, for thin-walled castings with double-sided round openings, the problem of wax deformation exists from the wax pattern stage. Even if the roundness is controlled within the acceptable range through the shaping structure at the wax pattern stage, the stress generated by metal shrinkage during subsequent pouring or the stress generated during the cleaning and transfer process can still cause the casting to deform, thus exceeding the roundness requirements of the casting drawings.

[0041] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.
[0042] like Figure 1 , Figure 4 As shown, the shaping device for double-layered round-mouth products provided in this embodiment has double-layered walls with a gap between the double-layered walls, forming an inner groove.
[0043] The shaping device for double-layer round-mouth products also includes: an arc-shaped shaping strip 100, an upper pressure plate body 10, a lower pressure plate body 30, and a limit replacement block 300.
[0044] The arc-shaped shaping strip 100 extends into the inner groove. The arc-shaped shaping strip 100 effectively prevents the inner groove from being squeezed and deformed during shaping.
[0045] The lower pressure plate body 30 has a lower semi-circular cavity for placing products. Specifically, one side of the lower pressure plate body 30 is recessed from top to bottom to form a lower semi-circular cavity.
[0046] The upper pressure plate body 10 has an upper semi-circular cavity for placing products; specifically, one side of the lower pressure plate body 30 is recessed from top to bottom to form a lower semi-circular cavity.
[0047] It is important to note that the upper and lower semicircular cavities are located on the same side, ensuring that during the pressing process, the upper and lower semicircular cavities form a circular cavity to extrude and shape the product.
[0048] The upper pressure plate body 10 is located above the lower pressure plate body 30, and the upper pressure plate body 10 can move vertically relative to the lower pressure plate body 30 so that the upper pressure plate body 10 and the lower pressure plate body 30 press the film to shape the product.
[0049] In an optional embodiment, an upper pressure plate body 10 is provided with an upper pressure plate equipment connecting plate 20 on its top surface. The upper pressure plate equipment connecting plate 20 is used to connect to a hydraulic device, which drives the upper pressure plate body 10 to move, thereby realizing the pressing of the film.
[0050] Alternatively, a lower pressure plate equipment connecting plate 40 can be provided on the bottom surface of the lower pressure plate body 30. The lower pressure plate equipment connecting plate 40 is used to connect hydraulic equipment.
[0051] It should be noted that the connection between the upper pressure plate equipment connecting plate 20 and the upper pressure plate body 10 is a fixed connection, that is, the upper pressure plate equipment connecting plate 20 and the upper pressure plate body 10 are an integral structure. The connection between the lower pressure plate equipment connecting plate 40 and the lower pressure plate body 30 is a fixed connection, that is, the lower pressure plate equipment connecting plate 40 and the lower pressure plate body 30 are an integral structure.
[0052] The limiting replacement block 300 is detachably installed on the top surface of the lower pressure plate body 30, and the limiting replacement block 300 protrudes from the top surface of the lower pressure plate body 30. Since the top surface of the limiting replacement block 300 is higher than the top surface of the lower pressure plate body 30, the setting of the limiting replacement block 300 can change the shaping pre-pressure amount during film pressing. Since the limiting replacement block 300 is detachably installed on the lower pressure plate body 30, spare limiting replacement blocks 300 of different specifications and models can be prepared to adjust the shaping pre-pressure amount.
[0053] The shaping device for double-layer round-mouth products provided in this embodiment involves inserting the casting product with the arc-shaped shaping strip 100 into the lower semi-circular cavity of the lower pressure plate body 30, pressing down the upper pressure plate body 10, and pressing the upper pressure plate body 10 and the lower pressure plate body 30 together. After pressing once, the casting product is rotated and pressed again until the casting is rotated 180 degrees, at which point the shaping is complete. The casting is then removed, and the arc-shaped shaping strip 100 is taken out. The shaping effect is good, the consistency is high, the shaping cost is low, and the shaping efficiency is high. Furthermore, since a limit replacement block 300 is detachably installed on the top surface of the lower pressure plate body 30, and the limit replacement block 300 protrudes from the top surface of the lower pressure plate body 30, the shaping pre-pressure amount can be adjusted according to the characteristics of different casting products, thereby achieving an adjustable shaping size.
[0054] Based on the above embodiments, such as Figure 2 , Figure 3 As shown, in an optional embodiment, the arc-shaped shaping strip 100 in the shaping device for double-layer round-mouth products provided in this embodiment is set as an arc-shaped block; one end of the arc-shaped block extends into the inner groove, and the end face of the other end of the arc-shaped block can abut against the bottom surface of the lower semi-circular cavity or the bottom surface of the upper semi-circular cavity, ensuring that the bottom surface of the arc-shaped block is aligned with the bottom surface of the semi-circular cavity of the pressure plate body.
[0055] In an optional implementation, multiple arc-shaped blocks are provided, and these multiple arc-shaped blocks are evenly spaced along the circumference of the inner groove to ensure compressive strength and effectively prevent the inner groove from being squeezed and deformed.
[0056] Additionally, it should be noted that, in order to facilitate the installation and removal of the arc-shaped shaping strip 100, a through hole is provided on the arc-shaped shaping strip 100. When the arc-shaped shaping strip 100 is inserted into the inner groove, the through hole is located outside the inner groove, making it easy for the operator to remove the arc-shaped shaping strip 100 from the inner groove using tools such as hooks.
[0057] In an optional embodiment, the top surface of the lower pressure plate body 30 is recessed to form a limit block placement groove, and the limit replacement block 300 is placed in the limit block placement groove.
[0058] In an optional embodiment, at least two limit block placement slots are provided, and each limit block placement slot is provided with a limit replacement block 300.
[0059] Alternatively, mounting holes can be provided on the limit replacement block 300, and the limit replacement block 300 can be connected to the limit block placement groove by means of bolts or other structures, so as to realize the free disassembly of the limit replacement block 300 in the limit block placement groove.
[0060] In an optional embodiment, a guide post 200 is provided on the top surface of the lower pressure plate body 30; a guide hole is provided on the bottom surface of the upper pressure plate body 10 at a position corresponding to the guide post 200; the guide post 200 can extend into the guide hole, thereby restricting the movement direction of the upper pressure plate body 10 relative to the lower pressure plate body 30 for pressing.
[0061] In an optional embodiment, two guide posts 200 are provided, and the two guide posts 200 are symmetrically arranged on the top surface of the lower pressure plate body 30.
[0062] In addition, the top surface of the guide post 200 has an inclined surface, which serves as a guide to facilitate the insertion of the guide post 200 into the guide hole, thereby restricting the movement direction of the upper pressure plate body 10 relative to the lower pressure plate body 30.
[0063] The shaping device for double-layer round-mouth products provided in this embodiment has good product shaping effect, high consistency, low shaping cost, and high shaping efficiency. The shaping device includes a limit replacement block 300, which can adjust the shaping pre-pressure amount according to the characteristics of different casting products, thereby achieving the technical effect of adjustable shaping size.
[0064] The hydraulic shaping equipment provided in this embodiment includes the shaping device for double-layer round-mouth products provided in the above embodiment.
[0065] Since the technical effect of the hydraulic shaping equipment provided in this embodiment is the same as that of the shaping device for double-layer round mouth products provided in the above embodiment, it will not be described again here.
[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it.
