Description

Technical Field

[0001] The utility model relates to the technical field of wax molds, and more specifically to a wax mold for casting automobile connecting rod parts. Background Art

[0002] Part casting wax mold is a precision casting technology used to produce parts with high dimensional accuracy and surface finish. Wax molds are widely used in the manufacture of automotive connecting rod parts. After the wax mold frame is heated and vaporized, the gas needs to be discharged from the vents opened on one side of the cover mold, but the external gas can easily enter the cover mold. When part of the wax mold frame melts, the external gas can easily pass through the vents and contact the workpiece, which can easily cause damage to the workpiece surface.

[0003] After searching, a Chinese patent with announcement number CN217166373U discloses a wax mold for casting automobile connecting rod parts. The through pipe presses the closed ring into the butt pipe, and the closed ring tightens the end of the through pipe and the inner wall of the butt pipe, thereby preventing the vaporized wax from being discharged through the matching gap between the through pipe and the butt pipe. When the one-way valve is not venting smoothly, the first nut can be screwed out of the second stud to disassemble the through pipe, thereby facilitating the heating of the vent hole, the vent pipe, the through pipe and the one-way valve until the previously condensed wax inside is vaporized, and then compressed air is used for air blowing. After completion, it can be reinstalled, thereby facilitating the removal of condensed wax and ensuring the exhaust effect.

[0004] When the above-mentioned wax mold is in use, since wax mold casting belongs to fusion casting, the mold needs to be melted after casting to facilitate the removal of material. However, since structures such as the butt tubes are fixed to the wax mold frame, it is not convenient to reuse structures such as the butt tubes after the wax mold frame melts, and the use effect is poor. Utility Model Content

[0005] In order to overcome the above defects of the prior art, the utility model provides a wax mold for casting automobile connecting rod parts, aiming to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a wax mold for casting automobile connecting rod parts, comprising a first wax mold and a second wax mold, and the second wax mold is located on the top of the first wax mold, and a base is movably provided at the bottom of the first wax mold, and an extrusion assembly is provided on the base, and the extrusion assembly comprises forward and reverse screw rods, a sliding rod, two vertical plates and a plurality of plug blocks, both ends of the forward and reverse screw rods are movably connected to the base through bearings, both ends of the sliding rod are fixedly connected to the base, and one end of the sliding rod and the forward and reverse screw rods pass through the two vertical plates, and one end of the plurality of plug blocks is respectively fixedly connected to the two vertical plates.

[0007] Furthermore, a first handle is movably provided inside the base, and the first handle is fixedly sleeved on the forward and reverse screw rods.

[0008] It can be seen that in the above technical solution, the forward and reverse screw rods are driven to rotate conveniently.

[0009] Furthermore, a bolt is movably provided at the inner center position of the base, and the base and the first wax mold are fixed by bolts, and two clamping plates are fixedly connected to the top of the first wax mold, and both clamping plates extend into the first wax mold.

[0010] It can be seen that in the above technical solution, the first wax model is placed on the base, and the two clamping plates can limit the deflection of the first wax model, and then the base and the first wax model are fixed by bolts.

[0011] Furthermore, a feed assembly is provided on the top of the second wax mold, and the feed assembly includes a threaded barrel, a feed hopper and a limiting plate.

[0012] Furthermore, the threaded barrel is threadedly connected to the second wax mold, one end of the feed hopper is fixedly connected to the threaded barrel, the limit plate is fixedly sleeved on the threaded barrel, and the bottom end of the limit plate is in contact with the second wax mold.

[0013] Furthermore, a sealing assembly is provided on the threaded barrel, and the sealing assembly includes a screw rod, a baffle and a second handle.

[0014] Furthermore, the screw rod is threadedly connected to the threaded barrel, and the bottom end of the screw rod is fixedly connected to the baffle, and the bottom end of the second handle is fixedly connected to the screw rod.

[0015] Technical effects and advantages of the utility model:

[0016] 1. The utility model places the second wax mold on top of the first wax mold, and then rotates the first handle so that multiple plugs can be inserted into the first wax mold and the second wax mold, thereby fixing the first wax mold, the second wax mold and the base. When the first wax mold and the second wax mold are melted, the base is taken out and installed on another first wax mold and another second wax mold. The base can be reused in this way, with good use effect and effective saving of casting cost.

[0017] 2. The utility model rotates the threaded barrel and extends it into the second wax mold. The limit plate limits the downward movement distance of the threaded barrel, and then pours the material into the feed hopper. The material enters the first wax mold and the second wax mold through the feed hopper and the threaded barrel. The second handle is rotated to drive the screw to rotate and move downward, thereby driving the baffle to move downward to prevent the material from flowing out through the threaded barrel. The structure is simple and easy to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Furthermore, a first handle 405 is movably provided inside the base 3, and the first handle 405 is fixedly sleeved on the forward and reverse screw rods 401. A bolt 8 is movably provided at the inner center position of the base 3, and the base 3 and the first wax mold 1 are fixed by the bolt 8. Two clamping plates 5 are fixedly connected to the top of the first wax mold 1, and the two clamping plates 5 extend into the first wax mold 1.

[0029] Furthermore, a feed assembly 6 is provided on the top of the second wax mold 2, and the feed assembly 6 includes a threaded barrel 601, a feed hopper 602 and a limit plate 603. The threaded barrel 601 is threadedly connected to the second wax mold 2, one end of the feed hopper 602 is fixedly connected to the threaded barrel 601, the limit plate 603 is fixedly sleeved on the threaded barrel 601, and the bottom end of the limit plate 603 is in contact with the second wax mold 2, and a sealing assembly 7 is provided on the threaded barrel 601. The sealing assembly 7 includes a screw rod 701, a baffle 702 and a second handle 703.
