Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of novel pad casting, and more specifically, to a novel pad casting mold. Background Art
[0002] The main pad connecting the frame and the axle, especially the torque pad that transmits the various forces between the axle and the frame. Due to the inconsistent height of the casting parts of the pad and its pad characteristics, sand loss in the part cavity and fleshy surface problems often occur. The pad processing meets the requirements of the drawing.
[0003] like Figure 1 and Figure 2 The pad shown is a common pad currently. Its inner wall is deep and the heights on both sides are not uniform, which can easily lead to sand falling off on both sides of the lower core of the pad formed by the inner walls 1 and 2 in the figure during sand casting, resulting in a fleshy surface of the molded parts, affecting the quality of the product and making it difficult to meet actual needs. Utility Model Content
[0004] The utility model provides a new type of pad casting mold to solve the problems of sand loss in the existing parts and excess flesh on the surface. The parts and their designs do not need to be changed and the strength of the parts is not affected. At the same time, the yield of the parts is improved.
[0005] According to one aspect of the utility model, a new type of pad casting mold is provided, including a lower mold for obtaining the pad cavity entity and an upper mold for obtaining the pad lower core, the upper mold includes a plate body and a support plate, the two sides of the plate body are bent downward to form a support plate, the upper part of the plate body is provided with an inner hole for forming the pad lower core, the bottom wall of the inner hole is open, the support plate is arranged between the two support plates, and a top column is provided on the upper part of the support plate, the top column extends to the opening of the inner hole, and a guide column is provided between the support plate and the plate body.
[0006] Preferably, based on the above solution, a sand box is provided on the plate body.
[0007] Preferably, based on the above solution, the lower mold includes a seat plate, a concave cavity is provided in the middle of the seat plate, and a protrusion for forming a pad cavity entity is provided in the middle of the concave cavity.
[0008] Preferably, based on the above solution, a sand box is provided on the seat plate.
[0009] Preferably, based on the above solution, the lower core of the pad formed by the upper die and the pad cavity formed by the lower die are physically adapted to form a sand mold for casting the pad.
[0010] The utility model discloses a new type of pad casting mold, which improves the upper mold for forming the lower core of the pad and adopts guide columns to achieve smooth movement between the support plate and the plate body. When the push column is pushed to move relative to the plate body, the lower core of the pad formed in the inner hole can be quickly ejected from the mold, effectively avoiding sand falling in the mold cavity and affecting the subsequent casting and molding, resulting in the problem of excess flesh inside the pad.

[0020] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0021] It will be understood that when used in this specification and the appended claims, the term "comprising" indicates the presence of described features, integers, steps, operations, elements and / or components, but does not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components and / or collections.
[0022] To simplify the drawings, only the parts relevant to the present invention are schematically shown in each figure. They do not represent the actual structure of the product. In addition, to simplify the drawings and facilitate understanding, in some figures, only one of the components with the same structure or function is schematically depicted or labeled. In this document, "one" not only means "only one" but also "more than one."
[0023] It should be further understood that the term "and / or" used in this specification and the appended claims refers to and includes any and all possible combinations of one or more of the associated listed items.
[0024] In the embodiments shown in the accompanying drawings, directional indications (such as up, down, left, right, front, and back) used to explain the structure and movement of various components of the present invention are not absolute but relative. These descriptions are applicable when these components are in the positions shown in the accompanying drawings. If the descriptions of the positions of these components are changed, these directional indications will also change accordingly.
[0025] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.
[0026] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without inventive work.
[0027] See also Figure 3 , and combined with Figure 4 and Figure 5 As shown, a new type of pad casting mold of the utility model includes a lower mold 20 for obtaining the pad cavity entity and an upper mold 10 for obtaining the pad lower core, the upper mold 10 includes a plate body 11 and a support plate 12, the two sides of the plate body 11 are bent downward to form support plates 13, the upper part of the plate body 11 is provided with an inner hole 14 for forming the pad lower core, the bottom wall of the inner hole 14 is open, the support plate 12 is arranged between the two support plates 13, and a top column 15 is provided on the upper part of the support plate 12, the top column 15 extends to the opening of the inner hole 14, and a guide column 16 is provided between the support plate 12 and the plate body 11; a sand box is provided on the plate body 11.
[0028] Please continue reading Figure 6As shown, the lower mold 20 of the present invention includes a base plate, a concave cavity 21 is provided in the middle of the base plate, and a protrusion for forming a pad cavity entity is provided in the middle of the concave cavity 21.
[0029] When in use, a sand box is provided on the seat plate. First, the lower mold 20 is formed, and sand 8 is filled in the sand box, and the sand is compacted and turned over to obtain the pad cavity entity; then the upper mold 10 is formed, and the molding sand is filled into the sand box. The sand in the sand box is compacted and formed by the vibration of the equipment to obtain the pad lower core, and then the mold is lifted. When lifting the mold, in order to avoid Figure 2 When sand falls off in the cavities at 1 and 2 of the inner walls, the lower core of the pad is ejected in a linkage manner. Specifically, the support plate 12 is pushed along the guide column 16 close to the plate body 11. At this time, the ejector column 15 will move toward the inside of the inner hole 14 to realize the ejection of the sand core in the inner hole 14, so as to obtain a complete lower core of the pad.
[0030] Finally, the backing plate lower core is physically combined with the backing plate cavity, and molten iron is poured from the sprue 7 to obtain a backing plate solid blank.
[0031] It should be noted that the lower core of the pad formed by the upper mold 10 of the present invention and the pad cavity formed by the lower mold 20 are physically adapted to form a sand mold for casting the pad.
[0032] The utility model provides a new type of pad casting mold, which improves the upper mold 10 for forming the lower core of the pad, adopts the guide column 16 to achieve smooth movement between the support plate 12 and the plate body 11, and when the push column 15 is pushed to move relative to the plate body 11, the pad lower core formed in the inner hole 14 can be quickly ejected and demolded, effectively avoiding sand falling in the cavity and affecting the later casting and molding, resulting in the problem of excess flesh inside the pad.
[0033] Finally, the method of this application is only a preferred embodiment and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of this utility model should be included in the scope of protection of this utility model.
