Description

Technical Field

[0001] The utility model relates to the technical field of valve body casting, in particular to a valve body casting mold. Background Technique

[0002] The definition of a valve body is a device used to control the direction, pressure, and flow rate of a fluid in a fluid system. A valve is a device that enables the medium (liquid, gas, powder) in a pipeline and equipment to flow or stop and can control its flow rate. During the production process of a valve body, it is usually formed by casting, and this process needs to be realized through a casting mold. Some valve body casting molds include an upper mold and a lower mold. Cavities are provided inside both the upper mold and the lower mold. When casting the valve body, first, the upper mold and the lower mold are vertically buckled together. Subsequently, some counterweights are placed above the upper mold to prevent the vertical separation between the upper mold and the lower mold during the subsequent injection molding process. Then, the molten raw material of the valve body is input into the cavity through the injection port, and then left to stand and form, thus realizing the casting of the valve body. However, during the contact and combination process of the upper mold and the lower mold, the staff manually drives the upper mold to vertically approach the lower mold. Since the upper mold has a certain weight, it is prone to being affected by gravity and colliding with the lower mold, which may easily cause collision damage between the contact surfaces of the upper mold and the lower mold and needs to be improved. Moreover, counterweights need to be placed on the upper side of the upper mold for each valve body casting, which is inconvenient to use. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to overcome the existing defects and provide a valve body casting mold. When casting the valve body with this device, elastic buffering is carried out during the vertical contact process of the upper mold and the lower mold, thereby avoiding collision damage between the two. At the same time, the device can limit the vertical movement of the upper and lower molds to prevent relative vertical movement between the two, and there is no need to rely on counterweights, which can effectively solve the problems in the background technique.

[0004] To achieve the above purpose, the utility model provides the following technical solution: A valve body casting mold, including a lower mold and an anti-collision sealing mechanism;

[0005] Lower mold: An upper mold is placed on its upper side;

[0006] Anti-collision sealing mechanism: It includes a fixed seat, a telescopic column, a buffer seat, a contact seat, a second chute, and a locking seat. The fixed seats are arranged on the front and rear sides of the lower mold. A buffer seat is provided at the upper side of each fixed seat through the telescopic end of evenly distributed telescopic columns. Contact seats are provided on the front and rear sides of the upper mold. Second chutes are opened on the front and rear sides of the lower mold. Locking seats are slidably connected to the inside of the second chutes. The buffer seats and the locking seats are cooperatively installed with the adjacent contact seats. When the device is casting the valve body, elastic buffering is carried out during the vertical contact process between the upper mold and the lower mold, thereby avoiding collision damage between the two. At the same time, the device can limit the vertical movement of the upper and lower molds to prevent relative vertical movement between the two, without the need to rely on counterweights.

[0007] Further, mold cavities are opened on the upper side of the lower mold and the lower side of the upper mold. First chutes are opened on the left and right walls of the lower mold. The bottom wall of the lower mold is provided with symmetrically distributed auxiliary ejector seats through the telescopic ends of telescopic rods. Push rods are provided on the lower sides of the auxiliary ejector seats. The push rods are slidably connected to the adjacent first chutes, facilitating the separation of the lower mold from the cast valve body.

[0008] Further, symmetrically distributed limit columns are provided on the bottom wall of the lower mold. The limit columns are cooperatively installed with the auxiliary ejector seats to limit the downward movement position of the auxiliary ejector seats in the valve body casting mold.

[0009] Further, the anti-collision sealing mechanism further includes springs. The springs are symmetrically arranged between the fixed seats and the adjacent buffer seats. The springs are movably sleeved on the outer ends of the adjacent telescopic columns. Through the compression elastic force of the springs, elastic buffering is carried out when the upper mold of the valve body casting mold approaches the lower mold vertically.

[0010] Further, handles are rotatably connected to the left and right sides of the upper mold. Symmetrically distributed mounting seats are provided on the lower side of the lower mold to fix the lower mold and perform moving operations on the upper mold.

[0011] Further, evenly distributed guide columns are provided on the lower side of the upper mold. Evenly distributed guide grooves are opened on the upper side of the lower mold. The guide columns are cooperatively installed with the guide grooves. Through the vertical insertion of the guide columns into the guide grooves, the upper mold and the lower mold are vertically aligned to avoid contact misalignment between the two.

[0012] Further, a rubber sealing ring is provided on the upper side of the lower mold to improve the sealing effect of the contact surface between the upper mold and the lower mold of the valve body casting mold.

[0013] Compared with the prior art, the beneficial effects of the present utility model are: This valve body casting mold has the following advantages:

[0014] When using the valve body casting mold, when the upper mold approaches the lower mold vertically, the compressive elastic force of the spring causes the contact seat to be elastically in contact with the buffer seat, thereby elastically buffering the vertical contact process between the upper mold and the lower mold, thus avoiding the phenomenon of collision damage between the two. The self-inclined plane of the locking seat slides and fixes along the contact seat, thereby limiting the vertical movement between the upper and lower molds and preventing relative vertical movement between the two, without the need to rely on counterweights.

Detailed Embodiment

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the 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.

[0020] Please refer to Figures 1-3 , this embodiment provides a technical solution: a valve body casting mold, including a lower mold 1 and an anti-collision and sealing mechanism 8;

[0021] Lower die 1: An upper die 2 is placed on its upper side. Mold cavities are provided on both the upper side of the lower die 1 and the lower side of the upper die 2. Slide grooves 3 are provided on both the left and right walls of the lower die 1. The bottom wall of the lower die 1 is provided with symmetrically distributed auxiliary ejector seats 4 through the telescopic ends of telescopic rods 5. Push rods 7 are provided on the lower sides of the auxiliary ejector seats 4, and the push rods 7 are all slidably connected to the adjacent slide grooves 3. The bottom wall of the lower die 1 is provided with symmetrically distributed limit posts 6, and the limit posts 6 are cooperatively installed with the auxiliary ejector seats 4. Handles 9 are rotatably connected to both the left and right sides of the upper die 2. Mounting seats 10 are symmetrically distributed on the lower side of the lower die 1. Guide posts 11 are evenly distributed on the lower side of the upper die 2. Guide grooves 12 are evenly distributed on the upper side of the lower die 1. When using the valve body casting mold, first, the device is fixed to the designated position through the mounting seats 10 with bolts. Subsequently, the operator slides the locking seat 87 along the slide groove 86 to the right end. Then, the operator drives the upper die 1 through the handle 9 to move vertically downward and approach the lower die 1. During this process, the upper die 2 and the lower die 1 are vertically aligned by vertically inserting the guide posts 11 into the guide grooves 12, avoiding contact misalignment between the two. After the upper and lower dies are fixedly connected, the valve body raw material is cast through the injection port of the upper die 2, left to stand and cool. Then, the locking seat 87 is toggled to move rightward and reset. The contact seat 85 drives the upper die 2 to move vertically upward by a certain distance through the compressive elastic force of the spring 83, so that the upper die 2 is separated from the cast valve body. Then, the upper die 2 is taken out. Then, the push rod 7 is pulled upward along the slide groove 3 to make the auxiliary ejector seat 4 move vertically upward, and the telescopic end of the telescopic rod 6 extends adaptively, so that the lower die 1 is separated from the cast valve body, facilitating the removal of the cast valve body. The downward movement position of the auxiliary ejector seat 4 is limited by the limit post 6;

[0022] Anti-collision sealing mechanism 8: It includes a fixed seat 81, a telescopic column 82, a buffer seat 84, a contact seat 85, a second chute 86 and a locking seat 87. The fixed seat 81 is arranged on the front and rear sides of the lower mold 1. A buffer seat 84 is provided at the upper side of each fixed seat 81 through the telescopic end of the uniformly distributed telescopic columns 82. Contact seats 85 are provided on the front and rear sides of the upper mold 2. Second chutes 86 are opened on the front and rear sides of the lower mold 1. Locking seats 87 are slidably connected inside the second chutes 86. Both the buffer seat 84 and the locking seat 87 are cooperatively installed with the adjacent contact seat 85. The anti-collision sealing mechanism 8 further includes springs 83. The springs 83 are symmetrically arranged between the fixed seat 81 and the adjacent buffer seat 84. The springs 83 are movably sleeved on the outer ends of the adjacent telescopic columns 82. The guide post 11 is cooperatively installed with the guide groove 12. A rubber sealing ring 13 is provided on the upper side of the lower mold 1. When the upper mold 2 is about to approach the lower mold 1, the contact seat 85 contacts the buffer seat 84. The buffer seat 84 is pressed, and the telescopic end of the telescopic column 82 and the spring 83 contract, thereby elastically buffering the vertical movement trend of the upper mold 2 relative to the lower mold 1 and avoiding relative damage caused by hard collision between the upper mold 2 and the lower mold 1. The sealing effect of the contact surface between the upper mold 2 and the lower mold 1 is improved through the rubber sealing ring 13. Then, the locking seat 87 is toggled to move along the second chute 86 towards the contact seat 85. The locking seat 87 presses the contact seat 85 through its own inclined surface, causing the contact seat 85 to drive the upper mold 2 to squeeze and approach the lower mold 1. The telescopic end of the telescopic column 82 and the spring 83 contract again, avoiding vertical movement between the upper mold 2 and the lower mold 1 during the later casting process of the valve body raw material, and further improving the casting sealing effect between the upper mold 2 and the lower mold 1 of the device.

[0023] The working principle of a valve body casting mold provided by the present utility model is as follows: When using the valve body casting mold, first, the device is fixed to the designated position by bolts through the mounting seat 10. Subsequently, the operator slides the locking seat 87 along the second chute 86 to the right end. Then, the operator drives the upper mold 1 to move vertically downward towards the lower mold 1 through the handle 9. During this process, the guide post 11 is vertically inserted into the guide groove 12, so that the upper mold 22 is vertically aligned with the lower mold 1, avoiding the phenomenon of contact misalignment between the two. When the upper mold 2 is about to approach the lower mold 1, the contact seat 85 contacts the buffer seat 84, and the buffer seat 84 is pressed. The telescopic end of the telescopic column 82 and the spring 83 contract, thereby elastically buffering the vertical movement trend of the upper mold 2 relative to the lower mold 1, avoiding relative damage between the upper mold 2 and the lower mold 1 due to hard collision. The sealing effect of the contact surface between the upper mold 2 and the lower mold 1 is improved through the rubber sealing ring 13. Then, the locking seat 87 is toggled to move along the second chute 86 towards the contact seat 85. The locking seat 87 presses the contact seat 85 through its own inclined surface, causing the contact seat 85 to drive the upper mold 2 to squeeze and approach the lower mold 1. The telescopic end of the telescopic column 82 and the spring 83 contract again, avoiding vertical movement between the upper mold 2 and the lower mold 1 during the later casting process of the valve body raw material, and further improving the casting sealing effect of the device between the upper mold 2 and the lower mold 1. Subsequently, the valve body raw material casting operation is carried out through the injection port of the upper mold 2, left to stand and cool. Then, the locking seat 87 is toggled to move rightward and reset. Through the compressive elastic force of the spring 83, the contact seat 85 drives the upper mold 2 to move vertically upward by a certain distance, so that the upper mold 2 is separated from the cast valve body. Then, the upper mold 2 is taken out. Then, the lever 7 is pulled upward along the first chute 3, and the telescopic end of the telescopic rod 6 extends adaptively, so that the lower mold 1 is separated from the cast valve body, facilitating the removal of the cast valve body. The lower limit position of the auxiliary ejector seat 4 is limited by the limit post 6.

[0024] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present utility model.
