Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of coated sand moulds, in particular to a coated sand casting mould. Background Art
[0002] When using molds to produce steel castings and iron castings, the upper and lower molds are generally used to complete the shaping of the product during the casting process. During the use of existing molds, all process layouts are formed by sand shells. To produce 30Kg products, the overall mold size will not exceed 800mm, and mold design and production and core shooting machine configuration can be achieved; when the product size and weight increase, the traditional coated sand process will make the sand shell size exceed 1000mm, so the mold size will be 1200mm, the mold cost is very high, and a special core shooting machine is required for shell making operations, which increases equipment costs. Utility Model Content
[0003] In view of this, the purpose of the present invention is to provide a coated sand casting mold to solve the problems pointed out in the above background technology.
[0004] In order to achieve the above utility model purpose, the technical solution adopted is as follows:
[0005] A coated sand casting mold comprises a lower mold, an upper mold, a riser, a runner, a pouring cup and an exhaust pipe, wherein the upper mold is mounted on the lower mold, a riser is mounted in the middle of the top end of the upper mold, the runner is fixed to one side of the top end of the upper mold, the pouring cup is fixed to the runner, an exhaust port is mounted on the other side of the top end of the mold, and an exhaust pipe is mounted on the exhaust port.
[0006] As a further improvement of the present invention, two exhaust ports are provided.
[0007] As a further improvement of the present invention, the size of the lower mold is 805mm×555mm×316mm.
[0008] As a further improvement of the present invention, the size of the upper mold is 830 mm×565 mm×234.4 mm.
[0009] The beneficial effects of the utility model are as follows: the pouring cup in the utility model is a universal component, and the riser is a purchased raw material. This part is applicable to all products and is the company's existing tooling. The total weight of the overall mold is 1.95 tons, and the total price is 62,400 yuan, while the traditional mold design will double the weight, thereby doubling the mold price. The utility model effectively solves the problem in the prior art that when the product size and weight increase, the traditional coated sand process will make the sand shell size exceed 1000mm, so the mold size will be 1200mm, the mold cost is very high, and a special core shooting machine is required for shell making operations, which increases the equipment cost. BRIEF DESCRIPTION OF THE DRAWINGS
[0010] The drawings constituting a part of this application are used to provide a further understanding of the present invention. The illustrative embodiments of the present invention and their descriptions are used to explain the present invention and do not constitute an improper limitation on the present invention. In the drawings:

[0012] Figure 2 This is a schematic diagram of the structure of the support base plate of the utility model.
[0013] In the figure: 1. lower mold, 2. upper mold, 3. riser, 4. runner, 5. pouring cup, 6. exhaust pipe, 7. exhaust port, 8. supporting base plate, 9. supporting leg, 10. limiting groove, 11. moving wheel. DETAILED DESCRIPTION
[0014] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0015] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.
[0016] Example 1
[0017] like Figure 1As shown, a coated sand casting mold includes a lower mold 1, an upper mold 2, a riser 3, a runner 4, a pouring cup 5 and an exhaust pipe 6. The upper mold 2 is installed on the lower mold 1, and the riser 3 is installed in the middle of the top of the upper mold 2. The runner 4 is fixed on one side of the top of the upper mold 2, and the pouring cup 5 is fixed on the runner 4. An exhaust port 7 is installed on the other side of the top of the mold, and an exhaust pipe 6 is installed on the exhaust port 7.
[0018] The exhaust pipe 6 is a tapered pipe that is larger at the top and smaller at the bottom.
[0019] The exhaust ports 7 are provided with two.
[0020] The size of the lower mold 1 is 805 mm×555 mm×316 mm.
[0021] The size of the upper mold 2 is 830 mm×565 mm×234.4 mm.
[0022] Example 2
[0023] Based on the structure of Example 1, in Example 2, Figure 2 As shown, it also includes a supporting base plate 8, and the lower mold 1 is placed on the supporting base plate 8. A limiting groove 10 matching the shape of the supporting leg 9 at the bottom of the lower mold 1 is opened on the supporting base plate 8, and a moving wheel 11 is installed at the bottom of the supporting base plate 8. Since the overall mass of the lower mold 1 and the upper mold 2 is heavy, the setting of the supporting base plate 8 and the moving wheel 11 facilitates the movement of the mold. In addition, the setting of the limiting groove 10 can form a stable support and limit for the lower mold 1, thereby avoiding shaking of the lower mold 1 and the upper mold 2 during the pouring process.
[0024] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. For those skilled in the art, the utility model may have various modifications and variations. Any modification, equivalent replacement, improvement, component splitting or combination, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
