Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of casting molding, in particular to a casting molding detection mold. Background Art
[0002] The forming casting with prefabricated parts generally needs to go through production steps such as assembling the mold shell, casting the product, curing the product, drying the casting material, and separating the prefabricated part mold in sequence.
[0003] The cast product completes the above process with the steel shell prefabricated part. In this process, the steel shell usually completely surrounds the internal casting material. In the existing production process, the surface state of the casting material exposed outside the steel shell is often used to judge the product state.
[0004] At present, for large-volume cast products with prefabricated parts, there are often cases where the surface state of the casting material exposed outside the steel shell is good, while the state and performance of the casting material inside the steel shell are poor. However, the state of the casting material inside the steel shell is not easy to detect. If detection is required, the steel shell often needs to be cut and the casting material removed for detection. However, the cut steel shell cannot be used continuously due to deformation, resulting in waste of material cost and labor cost; it often flows into the subsequent process, making it difficult to guarantee the product quality; and since the steel shell completely covers the outside of the casting material, for products with a relatively fast solidification rate, the gas during the casting process cannot be discharged from the product, further reducing the material density of the internal casting material and further affecting the product quality. Content of the Utility Model
[0005] The purpose of the utility model is to provide a casting molding detection mold, which can comprehensively detect the casting material during the casting process, taking into account the product quality while ensuring the material cost and labor cost; at the same time, it can further solve the problem that the gas cannot be discharged from the product during the casting process, resulting in a decline in product quality.
[0006] To achieve this purpose, the utility model adopts the following technical solutions:
[0007] The casting molding detection mold includes:
[0008] The first half mold;
[0009] The second half mold, the first half mold and the second half mold can be buckled with each other and enclose a cavity for the casting material to form, and the first half mold and the second half mold are detachably connected;
[0010] One of the first half mold and the second half mold is provided with an exhaust hole, and the exhaust hole is communicated with the cavity.
[0011] As an alternative solution for a casting and molding inspection mold, on opposite sides of the outer wall of the first half mold, first connecting ears protrude outward respectively, and on opposite sides of the outer wall of the second half mold, second connecting ears protrude outward respectively. The first connecting ears and the second connecting ears are arranged in relative contact, and the first connecting ears and the second connecting ears are connected by threaded fasteners.
[0012] As an alternative solution for a casting and molding inspection mold, a first handle is provided on the outer wall of the first half mold, and a second handle is provided on the outer wall of the second half mold.
[0013] As an alternative solution for a casting and molding inspection mold, the casting and molding inspection mold further includes a core rod, and a partial structure of the core rod is inserted into the cavity.
[0014] As an alternative solution for a casting and molding inspection mold, a handle is connected to one end of the core rod located outside the cavity.
[0015] As an alternative solution for a casting and molding inspection mold, the casting and molding inspection mold further includes a bottom plate, and the first half mold and the second half mold are detachably connected to the bottom plate.
[0016] As an alternative solution for a casting and molding inspection mold, a limiting groove is provided on the bottom plate, and the first half mold and the second half mold are placed in the limiting groove.
[0017] As an alternative solution for a casting and molding inspection mold, a first connecting plate is provided on the outer wall of the first half mold, and the first half mold is detachably connected to the bottom plate through the first connecting plate. A sliding groove is provided on the first connecting plate, and the threaded fastener can adjust its position along the sliding groove and be screwed to the bottom plate.
[0018] As an alternative solution for a casting and molding inspection mold, a second connecting plate is provided on the outer wall of the second half mold, and the second half mold is detachably connected to the bottom plate through the second connecting plate.
[0019] As an alternative solution for a casting and molding inspection mold, the exhaust hole is communicated with the suction pipe of a vacuum pumping device.
[0020] Beneficial effects:
[0021] In the present utility model, when the detection mold is in use, first, the first half mold and the second half mold are assembled, and casting material is injected into the cavity. As the casting and curing processes proceed, the high-temperature gas inside is discharged to the outside through the exhaust holes, thereby ensuring that the gas inside the product is fully discharged, avoiding the formation of pores by these gases inside the product, which would reduce the strength of the prefabricated part, cause erosion and cracks during use, effectively ensuring the density of the product and improving the strength and quality of the product. Further, after the product has been cured for a certain period of time, the operator can separate the first half mold and the second half mold to comprehensively detect the casting material wrapped inside during the casting process. This detection has many advantages. Firstly, it avoids the method in the prior art where the product needs to complete the entire process route and the casting material is completely cured and formed, then the steel shell is cut and the casting material product is taken out for product detection, taking into account product quality while ensuring material costs and labor costs. Secondly, compared with the method in the prior art of sampling and detecting the casting material partially exposed outside the steel shell and using the sampling detection of the exposed casting material outside to judge the overall state of the casting material, it can conveniently obtain a true state detection result as a whole, avoiding the problem that when the casting material exposed outside the steel shell has solidified while the casting material inside the steel shell has not solidified, and the product enters the subsequent process prematurely, resulting in a decline in product performance or even directly producing defective products. Thirdly, this detection mold can be opened at any time during the production process to check the state and performance of the internal casting material, assisting the operator to understand the key control points, and thus improving the production process according to relevant information.

Therefore, it should not be construed as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.
[0030] Please refer to the attached Figure 1 and the attached Figure 2 , this embodiment relates to a casting molding detection mold (hereinafter referred to as "detection mold"), which is used to realize the casting molding of prefabricated parts and can conveniently detect the internal molding state. Specifically, the detection mold includes a first half mold 1 and a second half mold 2; the first half mold 1 and the second half mold 2 can be buckled with each other and enclose a cavity for the casting material to be molded, and the first half mold 1 and the second half mold 2 are detachably connected; one of the first half mold 1 and the second half mold 2 is provided with an exhaust hole 3, and the exhaust hole 3 communicates with the cavity.
[0031] In this embodiment, the first half mold 1 and the second half mold 2 are two relatively mirror-symmetrical structures as a whole, wherein the first half mold 1 and the second half mold 2 are both two semi-cylinders, wherein materials are removed from the inside of the first half mold 1 and the second half mold 2 to buckle and enclose a cavity for pouring castables; meanwhile, the first half mold 1 and the second half mold 2 are detachably connected on the outer wall, which can be achieved by screw connection or clamping, etc. Further, an exhaust hole 3 is opened on the wall surface near the top of the first half mold 1, and the exhaust hole 3 is connected to the cavity.
[0032] When the inspection mold is in use, first, the first half mold 1 and the second half mold 2 are assembled, and the whole is placed upright in a preset molding position. There is a material port on the top for injecting the casting material, and the material port is connected to the cavity. The casting material is injected into the cavity through the material port. As the pouring and curing process proceeds, the high-temperature gas inside is discharged to the outside through the exhaust hole 3, thereby ensuring that the gas inside the product is fully discharged, avoiding the formation of pores in the product by these gases, thereby reducing the strength of the prefabricated parts, causing erosion and cracks during use, effectively ensuring the density of the product, and improving the strength and quality of the product.
[0033] Furthermore, after the product has been solidified for a certain period of time, the operator can separate the first half mold 1 and the second half mold 2, and conduct a comprehensive inspection of the castable wrapped inside during the pouring process. This inspection has many advantages. First, it avoids the method in the prior art that the product needs to go through the complete process route completely and the castable is completely solidified and formed, and then the steel shell is cut to take out the castable product for product inspection, taking into account product quality while ensuring material cost and labor cost; second, compared with the sampling inspection of the castable partially exposed to the outside of the steel shell in the prior art, the method of judging the state of the entire castable by sampling the castable exposed to the outside at the same time can conveniently obtain the real state inspection result from the whole, avoiding the problem that when the castable exposed to the outside of the steel shell has been solidified, the castable inside the steel shell has not been solidified, and the product is allowed to enter the subsequent process too early, resulting in a decrease in product performance, or even directly generating waste; third, the inspection mold can be opened at any time during the production process to check the state and performance of the internal castable, assisting the operator to understand the key control points, so as to improve the production process according to relevant information.

The first connecting ear 11 and the first half-mold 1 can be integrally formed or connected by welding or other means. Of course, the second connecting ear 21 can also be integrally formed or connected by welding or other means. When the first half-mold 1 and the second half-mold 2 are buckled together, the first connecting ear 11 and the second connecting ear 21 on the same side are opposite to each other. Mounting holes are correspondingly provided in the first connecting ear 11 and the second connecting ear 21. The bolt in the threaded fastener can pass through the mounting hole and be locked by a nut on the other side. Those skilled in the art can understand that the thickness of the first connecting ear 11 and the second connecting ear 21 can be adjusted specifically according to the volume of the casting material and the connection strength.
