Description

Technical Field

[0001] The utility model relates to casting demoulding technology, in particular to a device capable of automatically separating a casting and molding sand from a mold and automatically vibrating and removing the molding sand on the surface of the casting, a rapid casting demoulding mechanism Background Art

[0002] Casting is a method of pouring liquid metal into a casting cavity adapted to the shape of a part and waiting for it to cool and solidify to obtain the part or blank. The material to be cast is mostly metal that was originally solid but heated to a liquid state, and the mold material can be sand, metal, or even ceramic, etc. Among them, for sand as the mold material, during the demoulding process, first, the casting and the sand wrapping the casting need to be separated from the mold (i.e., the moving mold described in this application), and then the sand is separated from the casting to obtain the casting blank. The existing mold demoulding generally adopts two methods: manual demoulding or mechanical demoulding. Manual demoulding causes a relatively large labor burden on workers and has a relatively low demoulding efficiency; mechanical demoulding also varies due to different settings of demoulding devices. For example, some demoulding devices do not provide enough support for the mold, the molding sand inside the mold, and the casting formed. For example, in the invention patent with the application publication number CN118060516A, the fixed mold is fixed relatively stably, but its moving mold only maintains the mold closing state with the fixed mold through a horizontally driven telescopic device. In this way, the moving mold, the molding sand inside the moving mold, and the casting formed will be misaligned with the fixed mold under the action of gravity, thus affecting the precision of the casting. Secondly, the steps of separating the casting from the fixed mold and the moving mold of this device are relatively cumbersome, and the efficiency is relatively low in industrial applications. Therefore, the applicant has developed and designed the casting demoulding device involved in this application to ensure that the overall weight of the moving mold, the fixed mold, the sand, and the casting is mainly supported by the bracket to reduce the casting precision problems caused by the misalignment between the two moving molds Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is that the existing casting demoulding device lacks support for the moving mold and the fixed mold in the vertical direction

[0004] Moreover, the problem that the steps of separating the moving mold, the fixed mold from the casting are cumbersome. In view of the above defects of the prior art, the utility model provides

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is as follows

[0006] A rapid casting demoulding mechanism is constructed, which includes a demoulding frame, a connecting rod, and two moving moulds. The two moving moulds can be combined to form a casting cavity. Two sliding rails are symmetrically arranged on the demoulding frame. The two moving moulds are slidably arranged on the sliding rails, and pulling components are provided at both ends of the demoulding frame. Support components are symmetrically arranged in the middle of the sliding rails. One end of the connecting rod is connected to the support component, and the other end passes through a through hole on the side wall of the moving mould. A connecting part casting cavity is formed between one end of the connecting rod close to the casting cavity and the through hole. After casting is completed, a connecting cylinder fixedly connected to the outer wall of the casting is formed in the connecting part casting cavity. The cast casting is connected to the support component through the connecting rod.

[0007] Preferably, a vibration structure is further included, and the vibration structure is used to vibrate and remove the sand adhered to the outer side wall of the casting.

[0008] Preferably, during demoulding, the two moving moulds move towards both ends of the demoulding frame under the pulling of the pulling component, and the casting and the sand are kept in place under the action of the support component.

[0009] Preferably, the demoulding frame includes a base, two side walls are arranged at both ends of the base, two sliding rails are symmetrically arranged between the two side walls, a pulling component is arranged outside the two side walls, the telescopic rod of the pulling component passes through the side wall and extends towards the middle of the demoulding frame, and a first hook is arranged at the end of the telescopic rod.

[0010] Preferably, the moving mould has a casting cavity with an opening on one side. Fixing ears for fixedly connecting the two moving moulds are arranged on the upper and lower surfaces of the moving mould. Sliding ends are symmetrically arranged on the left and right side walls of the moving mould. Each sliding end has a semi-circular arc-shaped chute with a downward opening. During use, the moving mould is slidably arranged on the sliding rail through the chute.

When the two combined moving moulds are arranged on the sliding rail, the second hook of each moving mould is connected to the first hook at the end of the telescopic rod on the corresponding side.

[0012] Preferably, the connecting rod includes a rod portion and a clamping portion. The clamping portion is fixedly connected to the rod portion. The rod portion is cylindrical, and the clamping portion is in an inverted conical shape. The through hole also includes a circular through hole matching the rod portion and a conical hole matching the clamping portion.

[0015] 1. The demolding frame of the present utility model is symmetrically provided with two slide rails. The sliding ends on the side walls of the two moving dies are provided with downward-opening semi-circular chutes, so that the two moving dies joined together can be slidably placed on the slide rails. Thus, the slide rails bear the weight of the two moving dies and the molding sand and the casting in the moving dies, so that the two moving dies are kept consistent in the horizontal direction, and thus there will be no misalignment in the vertical direction. Therefore, there will be no defect problem in the accuracy of the casting caused by the misalignment of the two moving dies.

[0025] In order to make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below. Apparently, the described embodiments are partial embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] As Figures 1-6 shown, an embodiment of the present utility model specifically discloses a rapid casting demoulding mechanism, which includes a demoulding frame 1, a connecting rod 2 and two moving moulds 3. The two moving moulds 3 can be combined to form a casting cavity 301. Two sliding rails 101 are symmetrically arranged on the demoulding frame 1. The two moving moulds 3 are slidably arranged on the sliding rails 101, and pulling components 4 are arranged at both ends of the demoulding frame 1. The pulling components 4 are used to pull the moving moulds 3 so that the two moving moulds 3 can slide on the sliding rails 101. Support components 5 are symmetrically arranged in the middle of the sliding rails 101. One end of the connecting rod 2 is connected to the support component 5, and the other end passes through a through hole on the side wall of the moving mould 3. A connecting part casting cavity 6 is formed between one end of the connecting rod 2 close to the casting cavity 301 and the through hole. After casting is completed, a connecting cylinder fixedly connected to the outer wall of the casting is formed in the connecting part casting cavity 6. The connecting rod 2 is connected to the casting through the connecting cylinder. Therefore, the casting formed by casting can be connected to the support component 5 through the connecting rod 2, and can still remain on the sliding rail after the two moving moulds 3 are separated from the casting.

[0027] During demoulding, the two moving moulds 3 move towards both ends of the demoulding frame 1 under the contraction of the pulling component 4. Since the casting and the moulding sand are held in place by the supporting component 5, during the movement, the two moving moulds 3 gradually separate from the casting or the moulding sand until they are completely separated. After separation, the moulding sand adhering to the outer surface of the casting is removed under the vibration of the vibration structure.

[0028] As Figure 1 and Figure 2 shown, the demoulding frame 1 of the device includes a base 102, and the base 102 is in the shape of a rectangular plate. At both ends of the upper surface of the base 102, two side walls 103 are provided, and the two side walls 103 are integrally connected to the base 102 by welding. Between the two side walls 103, two slide rails 101 are symmetrically arranged. The two slide rails 101 are close to the upper middle part of the side walls 103, and the two slide rails 101 are in the same horizontal plane. In this way, when the assembled moving moulds are arranged on the slide rails, they are in a horizontal state, which is beneficial to the casting operation.

[0029] In addition, in some embodiments, a pulling component 4 is provided on the outer sides of the two side walls. The pulling component 4 is used to pull the corresponding moving mould 3 along the slide rail 101 towards the end of this side to separate the two moving moulds 3. To facilitate the connection between the pulling component 4 and the moving mould 3, the telescopic rod of the pulling component 4 passes through the side wall 103 and extends towards the middle of the demoulding frame 1, and a first hook 401 is provided at the end of the telescopic rod.

[0030] As Figure 4 and Figure 5 shown, the moving mould 3 has a casting cavity 301 with an opening on one side. On the upper and lower surfaces of the moving mould 3, fixing lugs 302 for fixedly connecting the two moving moulds are provided. On the left and right side walls of the moving mould 3, sliding ends 303 are symmetrically provided (it should be noted that the left and right side walls here refer to a pair of adjacent side walls with fixing lugs 302). Each sliding end 303 has a semi-circular arc-shaped chute 303a with a downward opening. The distance between the two chutes 303a is equal to the distance between the two slide rails 101. During use, the moving mould 3 is slidably arranged on the slide rail 101 through the chute 303a.

[0031] To cooperate with the first hook 401 on the pulling component, outside the bottom of the casting cavity 301 of each moving mould 3 (the bottom here refers to the side of the moving mould opposite to the opening of the casting cavity), a second hook 305 matching the first hook 401 at the end of the telescopic rod of the pulling component 4 is provided. When the two assembled moving moulds 3 are arranged on the slide rail 101, the second hook 305 of each moving mould is connected to the first hook 401 at the end of the corresponding telescopic rod.

[0032] It should be noted that the opening of the first hook 401 faces away from the base 102. When the moving die 3 is placed on the slide rail 101, the opening direction of the second hook 305 is opposite to that of the first hook 401. The connection operation is as follows: control the extension length of each pulling component 4 so that the distance between the two first hooks 401 is equal to the distance between the two second hooks 305 on the two moving dies 3 joined together.

[0033] In some embodiments, as Figure 4 and Figure 6 shown, the connecting rod 2 includes a rod portion 201 and a clamping portion 202. The clamping portion 202 and the rod portion 201 are of an integral structure. The rod portion 201 is cylindrical, and the clamping portion 202 is in an inverted conical shape; the through hole 304 also includes a circular through hole 304a matching the rod portion and a conical hole 304b matching the clamping portion 202; the inner wall of the conical hole 304b and the clamping portion 202 directly form a connecting portion casting cavity 6, and the connecting portion casting cavity forms a connecting cylinder after casting.

[0034] In some embodiments, the support assembly 5 is as follows: an installation plate 501 is arranged in the middle of each slide rail 101. An extendable fixed sleeve 502 is arranged on the inner side of each installation plate 501, and a vibration structure 503 is arranged on the outer side. The extendable fixed sleeve 502 includes a fixed part and a telescopic part, and the two are controlled to be telescopic manually by the operator. Specifically, both the fixed part and the telescopic part are in a cylindrical structure. One end of the fixed part is fixedly arranged on the installation plate 501, and the telescopic part is telescopically inserted into the fixed part. During use, the connecting rods 2 on the corresponding sides of the two fixed sleeves 502 are inserted and connected to each other, so that after the two moving dies 3 move to both sides respectively and are separated from the casting, the support assembly 5 can provide support for the casting and the molding sand attached to the surface of the casting. The operation of connecting the support assembly 5 and the connecting rod 2 is as follows. Before placing the joined moving dies 3 on the slide rail 101, first adjust the two extendable fixed sleeves 502 to the contracted state so that the distance between the two fixed sleeves 502 is greater than the distance between the outer ends of the connecting rods 2 arranged on the moving die 3 to ensure that the connecting rod 2 and the fixed sleeve 502 will not affect each other during the process of placing the moving die on the slide rail 101. After the moving die 3 is completely placed on the slide rail 101, adjust the position of the moving die 3 on the slide rail 101 so that the axes of the connecting rod 2 and the fixed sleeve 502 coincide, and then manually control to sleeved the fixed sleeve 502 on the connecting rod 2. Among them, the vibration structure is used to vibrate and remove the molding sand adhered to the outer wall of the casting. Specifically, the vibration structure is a vibration motor, and the vibration motor is fixedly arranged on the outer side of the installation plate 501 through bolts.

[0035] Finally, it should be noted that in order to facilitate the movement of the moving mold 3, lifting lugs are also provided at the top of the moving mold to facilitate the movement of the moving mold through lifting equipment. A semicircular casting port is provided at the top of each moving mold. When the two moving molds are assembled together, the two semicircular casting ports form a circular casting channel.

[0036] It should be understood that the present utility model is described through some embodiments. Those skilled in the art know that without departing from the spirit and scope of the present utility model, various changes or equivalent replacements can be made to these features and embodiments. Additionally, under the teaching of the present utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application belong to the scope protected by the present utility model.
