Description

Technical Field

[0001] This utility model relates to the field of ball valve injection mold technology, specifically to an injection mold for a ball valve body. Background Technology

[0002] Ball valves are mainly used in pipelines for shut-off, distribution, and changing the flow direction of media, and are therefore widely used in various fields. In the production process of ball valves, injection molds are required. The injection molds can increase the production efficiency of ball valves, so they play a very important role in the production process of ball valves.

[0003] In the current ball valve injection mold, for ease of operation, the injection material is directly fed into the mold core. Since the injection material usually enters the mold core from one inlet, the injection material is prone to uneven flow and cannot flow evenly into the mold core, thus affecting the ball valve injection effect. Utility Model Content

[0004] The purpose of this invention is to provide an injection mold for a ball valve body, so as to solve the problem of uneven material flow that is easily caused by the ball valve injection molds currently in use, as mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an injection mold for a ball valve body, comprising: a shell and a right mold base, a top cover installed on the top of the shell, a lower mold base installed inside the shell, a mold core provided on the top of the lower mold base, an upper mold base installed on the top of the mold core, and the right mold base installed on one side of the lower mold base and the upper mold base;

[0006] The mold core has a column core installed inside, and two sets of mold cores are fitted with transmission gears on their outer sides. The bottom of the transmission gears is meshed with a drive gear.

[0007] Preferably, the drive gear has a drive shaft that passes through the middle of the right mold base and is connected to it, and the input end of the drive shaft is connected to a drive motor via a coupling.

[0008] Preferably, a connecting block is connected to one side of the right mold base, and a cylinder penetrating the outer shell is connected to one side of the connecting block.

[0009] Preferably, a connecting pipe is sleeved on the outer side of the mold core, and a casting pipe penetrating the upper mold base is installed on the top of the connecting pipe.

[0010] Preferably, two sets of mold cores are symmetrically installed about the center line of the upper mold base, and the mold cores form a rotating structure through the transmission gear and the drive gear.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: When using the injection mold for the ball valve body, the injection material to be used for the ball valve can be transported into the mold core through the casting pipe according to the usage requirements. Then, the drive motor is started, which drives the drive gear to rotate through the transmission shaft. Since the drive gear and the transmission gear mesh with each other, the rotation of the drive gear will drive the rotation of the transmission gear. At the same time, the transmission gear is sleeved on the outside of the mold core, and the rotation of the transmission gear will drive the rotation of the mold core. When the mold core rotates, the injection material can flow evenly inside the mold core, so that the material can be evenly filled inside the mold core, thereby improving the production quality of the ball valve. This is the characteristic of the injection mold for the ball valve body. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not 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 effort are within the protection scope of the present utility model.

[0019] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5This utility model provides a technical solution: an injection mold for a ball valve body, comprising: a shell 1 and a right mold base 6, a top cover 2 installed on the top of the shell 1, a lower mold base 3 installed inside the shell 1, a mold core 4 provided on the top of the lower mold base 3, an upper mold base 5 installed on the top of the mold core 4, and the right mold base 6 installed on one side of the lower mold base 3 and the upper mold base 5.

[0020] The mold core 4 has a column core 7 installed inside. The outer sides of the two sets of mold cores 4 are fitted with transmission gears 8. The bottom of the transmission gears 8 is meshed with a drive gear 9. The middle of the drive gear 9 passes through the right mold base 6 and is connected to a transmission shaft 10. The input end of the transmission shaft 10 is connected to a drive motor 11 through a coupling. A connecting block 12 is connected to one side of the right mold base 6. A cylinder 13 that passes through the outer shell 1 is connected to one side of the connecting block 12. A connecting pipe 14 is fitted to the outer side of the mold core 4. A casting pipe 15 that passes through the upper mold base 5 is installed at the top of the connecting pipe 14. Two sets of mold cores 4 are symmetrically installed about the center line of the upper mold base 5. The mold core 4 forms a rotating structure between the transmission gears 8 and the drive gears 9. The bottom of the transmission shaft 10 is connected to the inside of the outer shell 1 through a bearing.

[0021] In practical implementation, when using the injection mold of the ball valve body, the raw materials required for ball valve injection can be transported into the mold core 4 through the pouring pipe 15 and the connecting pipe 14. Then, the drive motor 11 is started, and the drive motor 11 drives the transmission shaft 10 to rotate through the coupling. A drive gear 9 is installed on the outside of the transmission shaft 10, and two sets of transmission gears 8 are meshed on the top of the drive gear 9. The rotation of the drive gear 9 will drive the transmission gear 8 to rotate. Since the transmission gear 8 is sleeved on the outside of the mold core 4, the rotation of the transmission gear 8 will drive the mold core 4 to rotate. The inside of the mold core 4 is filled with the raw materials required for ball valve injection. When the mold core 4 rotates, the raw materials for ball valve production can be evenly filled inside the mold core 4, thereby making the ball valve injection effect better and preventing uneven local raw material. Furthermore, since the connecting pipe 14 is sleeved on the outside of the mold core 4, the mold core 4 will not be interfered with by the connecting pipe 14 when it rotates.

[0022] After injection molding is completed, cylinder 13 can be activated, which will pull the core 7 inside the mold core 4 out of the mold core 4 through connecting block 12 and right mold base 6. At this time, the right mold base 6 can be separated from the upper mold base 5 and the lower mold base 3. Without the obstruction of the right mold base 6, the ball valve after injection molding can be quickly removed from the mold core 4, thus facilitating quick material removal.

[0023] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As can be seen, during use, the drive motor 11 can drive the transmission shaft 10 and the drive gear 9 to rotate. The rotation of the drive gear 9 will drive the two sets of transmission gears 8 at the top to rotate, so that the transmission gears 8 drive the two sets of mold cores 4 to rotate. Through the rotation of the two sets of mold cores 4, the injection molding material of the ball valve can be evenly filled into the mold core 4, thereby making the injection molding effect of the ball valve better.

[0024] In summary, when using the injection mold for the ball valve body, the raw material for ball valve injection can be injected into the mold core 4 through the pouring pipe 15 on one side of the outer shell 1. Then, the drive motor 11 and the transmission shaft 10 drive the drive shaft and the transmission gear 8 to rotate, thereby causing the mold core 4 to rotate. This allows the raw material inside the mold core 4 to flow evenly into the mold core 4. The entire mold core 4 is installed in the outer shell 1 through the upper mold base 5, the lower mold base 3, and the right mold base 6, which increases the stability of the entire mold core 4. After the raw material cools and solidifies, the cylinder 13 and the connecting block 12 can drive the column core 7 to move out of the mold core 4, thereby facilitating the removal of the ball valve inside the mold core 4 and subsequent processing of the ball valve. This is the characteristic of the use of the injection mold for the ball valve body. The contents not described in detail in this description belong to the prior art known to those skilled in the art.

[0025] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
