Description

Be used for as cast mould of planet carrier Technical Field The utility model belongs to the technical field, and particularly relates to a mold for casting a planet carrier. Background In the foundry industry, it has been a challenge to produce castings with complex internal structures or high precision requirements. Conventional casting methods typically rely on sand cores to form the internal cavities or other complex shapes of the castings. However, the method has some limitations, such as complex manufacturing process of the sand core, high cost and difficulty in ensuring the dimensional accuracy and stability, and meanwhile, the sand core can be deformed or broken in the high-temperature casting process, so that the quality of the casting is unstable, and the rejection rate is increased. How to solve the above problems to improve the casting quality and the production efficiency is a technical problem to be solved in the industry. Disclosure of utility model The utility model aims to solve the problems in the prior art, and provides a die with lower cost and more stable casting quality. The object of the utility model is achieved by a mould for the casting of a planet carrier comprising: the first die is provided with a first forming groove; The second mould, first mould with can dismantle between the second mould and be connected, be provided with the second shaping groove on the second mould, when first mould with the second mould is fixed mutually, first shaping groove with form the shaping chamber between the second shaping groove, the material of second mould is the steel, be provided with the loam core in the second mould, be provided with the pouring slot on the diapire of second mould, the pouring slot with form the pouring chamber that sets up with the die cavity intercommunication between the loam core. In one of the above molds for casting a planet carrier, the second mold has a wall thickness 1 to 1.2 times the wall thickness of the casting. In the above mold for casting a planet carrier, a reinforcing ring is provided at the bottom of the second mold, a reinforcing rib is provided in the reinforcing ring, and the reinforcing rib extends from the center position of the second mold toward the reinforcing ring. In the mold for casting the planet carrier, lifting lugs are arranged on the outer annular wall of the reinforcing ring. In the mold for casting the planet carrier, the splicing surface of the second mold is provided with the test block groove, when the first mold is fixed with the second mold, a test block cavity is formed between the test block groove and the first mold and is communicated with the molding cavity, or a test block core is placed in the test block groove, and the test block cavity is communicated with the molding cavity. In the above mold for casting the planet carrier, a mud rope groove is provided on the splicing surface of the second mold. In the above mold for casting a planet carrier, a positioning hole is formed in a splicing surface of the second mold, a positioning pin is inserted into the positioning hole, and when the first mold and the second mold are spliced and closed, two ends of the positioning pin respectively extend into the splicing surface of the first mold and the splicing surface of the second mold. In the above mold for casting a planet carrier, two ends of the positioning pin are symmetrically arranged as round tables. In the above mold for casting a planet carrier, a mounting groove is formed in the center of the forming groove, the core is fixedly inserted into the mounting groove, and the casting groove is formed around the mounting groove and is communicated with the mounting groove. In the above-mentioned mold for casting a planet carrier, a molding hole is formed in a casting surface of the second mold, a molding portion is detachably disposed in the molding hole, and when the first mold and the second mold are assembled and closed, one end of the molding portion extends into the first mold. Compared with the prior art, the utility model has the beneficial effects that: (1) The casting mold has the advantages that the second mold made of integral steel is combined with the clay core arranged in the mold to form a casting system, compared with a traditional full-ceramic pipe casting method, the production cost is remarkably reduced, the casting quality is ensured, meanwhile, the production process is simplified, and secondly, due to the fact that molten iron and steel shrinkage rate are different, the mold stripping process after casting cooling is facilitated by using the steel mold, and the risk of casting deformation or surface defects caused by inconsistent shrinkage is reduced. In addition, the high-precision casting surface of the steel die ensures the dimensional precision and the surface finish of the final casting, and improves the quality and consistency of products. (2) The molding groove is directly processed on the steel mold,
