Description

Technical Field

[0001] The utility model relates to the technical field of precision casting, in particular to a vibration machine used for investment casting. Background Art

[0002] Investment casting is also called lost wax casting, which mainly includes the processes of wax pressing, wax repairing, tree assembly, slurry dipping, dewaxing, casting, shell shaking, sprue breaking, sand cleaning, etc. The purpose of the shell shaking process is to shake off the shell on the surface of the tree assembly after pouring, and the purpose of the sprue breaking process is to shake off the product in the tree assembly.

[0003] The shell shaking process and the sprue breaking process are usually completed by a shell shaking machine. When the shell shaking machine is working, the shell shaking process is usually carried out first, and then the sprue breaking process is carried out. The vibration pressure used in the shell shaking process is smaller than the vibration pressure used in the sprue breaking process to prevent the products that fall off from being mixed with the shell fragments. However, if the casting product is a relatively brittle carbon steel product, the casting product is very likely to fall off together with the shell fragments during the shell shaking process, seriously affecting the work efficiency. Utility Model Content

[0004] Based on this, it is necessary to provide a vibration machine for investment casting to address the problem that the cast product is very easy to fall off together with the shell fragments during the shell vibration process, which seriously affects the work efficiency.

[0026] The utility model discloses a vibrating machine used for investment casting.

[0027] like Figures 1 to 4As shown, the vibration machine for investment casting includes a machine table 10, which is used to vibrate the die set 20. A vibration head 11 is provided on the upper side of the machine table 10, and an inclined slide 12 is provided on the lower side of the machine table 10. A vibration platform 13 is provided at the middle of the inclined slide 12 corresponding to the position of the vibration head 11. A protective cover 111 and a vibration column 112 are formed at the end of the vibration head 11, and the vibration column 112 is formed at the inner center of the protective cover 111. The die set 20 includes a die head 21 and a product 22. The upper end of the die head 21 is fixedly mounted on the inner side of the protective cover 111 and abuts against the vibration column 112. The lower end of the die head 21 is fixed on the vibration platform 13, and the vibration platform 13 is provided with a groove matching the lower end of the die head 21.

[0028] Due to the casting process, the die head 21 and the product 22 are connected together, and a shell is fixedly connected to the outside of the product 22. When the vibration machine for investment casting is working, the vibration head 11 transmits the vibration to the die head 21 through the vibration column 112, and the vibration is further transmitted to the product 22 by the die head 21. The vibration of the vibration head 11 includes two stages. The vibration frequency of the first stage is relatively low, and the purpose is to break and fall off the shell fixed to the outside of the product 22. The vibration frequency of the second stage is relatively high, and the purpose is to break the connection between the product 22 and the die head 21, so that the product falls off. In the first stage, the fallen shell fragments fall from the product 22 to the inclined slide 12, and slide down along the inclined slide 12, so that the product 22 is separated from the shell fixed to the outside. In the second stage, the fallen product 22 falls from the die head 21 to the inclined slide 12, and slides down along the inclined slide 12, so that the product 22 is disconnected from the die head 21, which is convenient for subsequent processes. During the vibration process of the first stage and the second stage, the grooves on the protective cover 111 and the vibration platform 13 can fix the module 20 to prevent the module 20 from slipping and causing damage to the product 22.

[0029] The vibration machine for investment casting includes a machine table, which is used to vibrate the die set; a vibration head is provided on the upper side of the machine table, an inclined slide is provided on the lower side of the machine table, and a vibration platform is provided in the middle of the inclined slide corresponding to the position of the vibration head; a protective cover and a vibration column are formed at the end of the vibration head, and the vibration column is formed at the inner center of the protective cover; the die set includes a die head and a product, the upper end of the die head is fixedly mounted on the inner side of the protective cover and abuts against the vibration column, the lower end of the die head is fixedly mounted on the vibration platform, and a groove matching the lower end of the die head is provided on the vibration platform. When the vibration machine for investment casting is working, the vibration is vibrated by the vibration head, and the vibration is transmitted to the die head and the product through the vibration column. When the vibration frequency is low, the shell of the outer side of the product is shattered, forming a shell fragment that falls off. When the vibration frequency is high, the connection between the product and the die head is disconnected, so that the cast product falls off smoothly. By setting a protective cover at the end of the vibration head and setting a groove on the vibration platform, the upper end of the die head can be fixed on the protective cover, and the lower end of the die head can be fixed on the vibration platform, so that the module will not slip and displace during the vibration process, effectively preventing the product from being damaged by collision.

[0030] The vibrating machine for investment casting further includes a collecting box 30 for cooperating with the inclined slide 12, and the collecting box 30 is installed at the lower side of the outlet end of the inclined slide 12. In the first stage, when the shell of the outer side of the product 22 is shattered, the shell fragments slide down along the inclined slide 12 and fall into the collecting box 30, so that the shell fragments can be collected, thereby reducing the burden of manual cleaning of the shell fragments. In the second stage, the shell fragments in the collecting box 30 can be poured out, so that the product 22 slides down and falls into the collecting box 30, thereby avoiding the product 22 and the shell fragments from being mixed together, which increases the burden of manual cleaning.

[0031] The inclined slide 12 is made of magnetic material, and a control switch 121 for controlling the opening and closing of the magnetic attraction function of the inclined slide 12 is provided at the bottom of the inclined slide 12. After the magnetic attraction function of the inclined slide 12 is turned on by the control switch 121, when the product 22 falls from the die 21 onto the inclined slide 12, if the product 22 is a magnetic material, the product 22 can be attracted by the inclined slide 12, thereby avoiding damage to the product 22 caused by the product 22 falling onto the collection box 30. The control switch 121 can be turned on or off according to actual needs.

[0032] A support column 31 is installed at the bottom of the collection box 30. The collection box 30 can be supported by the support column 31, so that the structure of the collection box 30 is more stable.

[0033] Among them, the side of the protective cover 111 is formed with an open groove 1111 that matches the die head 21. The open groove 1111 can limit the upper end of the die head 21 to prevent the die head 21 from being displaced. Further, the open groove 1111 includes a first open groove and a second open groove, and the first open groove is arranged opposite to the second open groove. By arranging the first open groove and the second open groove opposite to each other, the effect of limiting the upper end of the die head 21 can be further enhanced.

[0034] The shape of the vibration platform 13 can be set according to actual needs. Preferably, the vibration platform 13 is cylindrical.

[0035] Furthermore, the shape of the vibration head 11 can be set according to actual needs. Preferably, the vibration head 11 is cylindrical, and the protective cover 111 protrudes from the end of the vibration head 11, which can cooperate to limit the upper end of the die head 21. The vibration column 112 is cylindrical, and the cross-sectional area of ​​the vibration column 112 is smaller than the cross-sectional area of ​​the vibration head 11. The cross-sectional area of ​​the vibration column 112 is smaller than the cross-sectional area of ​​the vibration head 11, so that the vibration of the vibration head 11 can be better transmitted.

[0036] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0037] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
