A mold for machining ball valve bodies

Abstract

This invention discloses a mold for processing ball valve bodies, comprising: a static template and a moving template, wherein the moving template is disposed on top of the static template, and injection holes are provided on both sides of the moving template. In use, when heat is concentrated and transported from the heat dissipation mesh plate, it enters the insulation pipe, preventing burns to the operator. The temperature rise within the insulation pipe increases the air pressure, creating a negative pressure that pushes the sealing piston forward, which in turn pushes the sliding rod forward until a contact block triggers the controller's switch, causing it to open. This activates the electric telescopic rod, which in turn extends and retracts. The electric telescopic rod then pulls the blocking slide plate, so that when the blocking slide plate extends forward, it blocks the section between the hopper and the connecting opening; when it retracts, it allows dry ice particles in the storage box to fall through the connecting opening into the feeding pipe.

Description

Technical Field

[0001] This invention relates to the field of metal manufacturing mold technology, specifically a mold for processing ball valve bodies. Background Technology

[0002] A ball valve is a pipeline accessory used to switch pipelines on and off, control flow direction, and regulate and control the parameters of the conveyed medium. A ball valve is a valve in which the opening and closing element (ball) is driven by the valve stem and rotates around the axis of the ball valve. It can also be used for the regulation and control of fluids.

[0003] In the prior art, such as Chinese Patent No. CN109014061A, a mold for processing ball valve bodies is disclosed, including an upper mold frame, a lower mold frame, a core, and a core-pulling device. The core includes a valve neck channel core and a medium channel core. The valve neck channel core includes a retaining element. The medium channel core has a first channel for the retaining element to move relative to the valve neck channel core. It also includes a guide element, which is axially movable within the medium channel core. The guide element includes a guide portion, and the guide portion has an inwardly inclined surface from the tail end to the top end on one side corresponding to the retaining element. A guide assembly is provided between the guide element and the retaining element, allowing the retaining element to move along the inclined surface of the guide portion. By adopting the above technical solution, when the guide element is pulled away in the core-pulling direction, the first and second inclined pressure blocks gradually move towards the center, thereby causing the protrusions of the first and second inclined pressure blocks to gradually disengage from the valve neck of the formed valve body, simplifying the operation process and improving work efficiency.

[0004] However, in the existing technology, ball valves, as a type of valve, have good sealing performance and are easy to open and close. With the rapid development of industrial level, the application range of ball valves is becoming more and more widespread. The ball valve body is usually processed by injection molding. However, the existing injection molding process generates very high temperatures after processing. High temperatures can easily cause accidental burns to operators, posing a safety hazard. It also makes the cooling time of the ball valve body after injection molding long, resulting in slow molding and reduced processing efficiency.

[0005] Therefore, we propose a mold for machining ball valve bodies to solve the problems mentioned above. Summary of the Invention

[0007] To achieve the above objectives, the present invention provides the following technical solution: a mold for processing ball valve bodies, comprising: a static template and a moving template, the moving template being disposed on top of the static template, injection holes being provided on both sides of the moving template, and a cooling pipe being provided on the inner wall of the static template; a feeding assembly, the feeding assembly comprising an L-shaped fixing rod, a storage box being fixedly installed on the top of the L-shaped fixing rod, a discharge hopper being fixedly installed between the inner walls of the storage box, a discharge pipe being fixedly connected to one side of the inner wall of the storage box, an electric telescopic rod being provided on one side of the L-shaped fixing rod, a blocking slide plate being fixedly installed at one end of the electric telescopic rod, and a communication port being provided on the top of the blocking slide plate; a venting assembly, the venting assembly comprising a heat insulation pipe, a movable cylinder being installed at one end of the heat insulation pipe, a sealing piston being movably connected to the inner wall of the movable cylinder, a sliding rod being fixedly installed on one side of the sealing piston, a contact block being fixedly connected to one end of the sliding rod, and one end of the sliding rod slidingly penetrating to the outside of the movable cylinder.

[0008] Preferably, a first air vent is provided on one side of the static template, a second air vent is provided on the rear surface of the static template, a ventilation channel is provided at one end of the first air vent, a heat dissipation mesh plate is fixedly installed between the inner walls of the ventilation channel, a connecting cover is fixedly connected to the outer surface of the ventilation channel, the other end of the heat insulation pipe extends into the interior of the connecting cover, and a one-way valve is provided on the outer surface of the heat insulation pipe.

[0009] Preferably, a fixed hose is fixedly connected to the outer surface of the insulation pipe, a fixed frame is fixedly installed on the rear surface of the static template, and a negative pressure pump is provided between the inner walls of the fixed frame.

[0010] Preferably, a first reinforcing rod is fixedly installed on one side of the static template, one end of which is fixedly connected to the outer surface of the insulation pipe, and a second reinforcing rod is fixedly installed on the rear surface of the static template, one end of which is fixedly connected to the outer surface of the insulation pipe.

[0011] Preferably, one end of the L-shaped fixing rod is fixedly connected to the rear surface of the static template, one end of the feeding pipe is fixedly connected to a tapered pipe, and one end of the tapered pipe is fixedly connected to one end of the second air outlet.

[0012] Preferably, a controller is provided at the top of the L-shaped fixed rod, and the controller is electrically connected to the electric telescopic rod.

[0013] Preferably, support rods are welded to the top of the static template near the four corners, and support plates are welded between the tops of the four support rods. The tops of the four support rods slide through to the top of the moving template.

[0014] Preferably, the top of the support plate is provided with multi-stage electric actuators, and the bottom end of the multi-stage electric actuators is fixedly installed with an mounting plate. The bottom of the mounting plate is installed on the top of the moving template by screws.

[0015] Preferably, the bottom of the moving template is provided with an upper forming groove, and the top of the stationary template is provided with a lower forming groove.

[0016] Preferably, a reinforcing block is fixedly installed on the other side of the storage box, and the cross-section of the reinforcing block is triangular.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. During use, heat is concentrated and transported from the heat dissipation mesh plate into the insulation pipe, preventing burns to operators. The temperature rise inside the insulation pipe increases the air pressure, creating a negative pressure that pushes the sealing piston forward, which in turn pushes the sliding rod forward until the contact block triggers the controller switch, opening it and activating the electric telescopic rod. At this time, the electric telescopic rod pulls the blocking slide plate, blocking the plate between the hopper and the connecting port when it extends forward, and allowing the dry ice particles in the storage box to fall through the connecting port into the discharge pipe when it retracts, thus sliding into the conical tube. After passing through the conical tube, it slides into the cooling pipe. When the dry ice encounters a high temperature, it instantly evaporates, generating cold air. The cold air circulates in the cooling pipe, effectively cooling the stationary mold plate. This solves the problem that the high temperature generated after processing in the existing injection molding process can easily cause accidental burns to operators, posing a safety hazard. It also solves the problem that the ball valve body has a long cooling time after injection molding, resulting in slow molding and reduced processing efficiency.

[0019] 2. During use, by opening the one-way valve, hot air can only be delivered in one direction and cannot flow back. By installing the fixed hose on the air inlet or outlet of the negative pressure pump according to the needs of air inlet and outlet, the negative pressure pump can be used as a backup. Starting the negative pressure pump will drive the sealing piston to move, thereby activating the contact block. This can prevent the automatic delivery of air pressure from being insufficient, which would cause the blocking slide to not move normally. Through the support of the first and second reinforcing rods, the insulation pipe can be effectively fixed. The end of the tapered tube with the smaller inner diameter is connected to the feed pipe, and the end with the larger inner diameter is connected to the second air outlet, which allows the dry ice particles to slide into the cooling pipe under inertia.

[0020] 3. During use, the position of the moving template is limited by the support rod to ensure that the positions of the stationary template and the moving template are corresponding. By activating the multi-stage electric actuator, the multi-stage electric actuator is extended, thereby driving the moving template to press down until it is in contact with the top of the stationary template. The molten metal is injected into the upper and lower forming tanks, which enables the ball valve body to be precisely formed. The stable support of the reinforcing block allows the blocking slide plate to slide on its surface, which can prevent one end of the blocking slide plate from tilting up when sliding.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Please see Figure 1-8The present invention provides a technical solution: a mold for processing ball valve bodies, comprising: a static template 1 and a moving template 3, the moving template 3 being disposed on top of the static template 1, injection holes 6 being provided on both sides of the moving template 3, and a cooling pipe 13 being provided on the inner wall of the static template 1; a feeding assembly 17, the feeding assembly 17 comprising an L-shaped fixing rod 1703, a storage box 1701 being fixedly installed on the top of the L-shaped fixing rod 1703, a discharge hopper 1702 being fixedly installed between the inner walls of the storage box 1701, a discharge pipe 1708 being fixedly connected to one side of the inner wall of the storage box 1701, an electric telescopic rod 1705 being provided on one side of the L-shaped fixing rod 1703, a blocking slide plate 1706 being fixedly installed at one end of the electric telescopic rod 1705, and a connecting port 1709 being provided on the top of the blocking slide plate 1706;The ventilation assembly 18 includes an insulation pipe 1801, with a movable cylinder 1802 installed at one end of the insulation pipe 1801. A sealing piston 1805 is movably connected to the inner wall of the movable cylinder 1802. A sliding rod 1806 is fixed to one side of the sealing piston 1805, and a contact block 1807 is fixedly connected to one end of the sliding rod 1806. One end of the sliding rod 1806 slides through to the outside of the movable cylinder 1802. During use, the ball valve body is processed by injecting molten metal into a mold for molding. At this time, a lot of heat is generated inside the mold, and the heat is concentrated and transported out through the heat dissipation mesh plate 11. The gas then enters the insulation pipe 1801 to prevent burns to the operator from the heat dissipation area. The temperature rises within the insulation pipe 1801, increasing the air pressure. This high pressure flows towards the movable cylinder 1802, creating a negative pressure that pushes the sealing piston 1805 forward, which in turn pushes the sliding rod 1806 forward until the touch block 1807 triggers the switch of the controller 1704, opening the circuit. The controller 1704 is pre-programmed so that each activation of the electric telescopic rod 1705 involves a reciprocating extension and retraction within a fixed time interval. This is achieved through the controller 1704 and the electric telescopic rod 1705... The electrical connection between 05 causes the controller 1704 to activate the electric telescopic rod 1705 to extend or retract. At this time, the electric telescopic rod 1705 drives the blocking slide plate 1706 to pull out. By matching the position and inner diameter of the round hole at the bottom of the hopper 1702, the connecting port 1709, and the feeding pipe 1708, the blocking slide plate 1706, when extended forward, blocks the plate between the hopper 1702 and the connecting port 1709. When retracted, the dry ice particles in the storage box 1701 can pass through the connecting port 1709 and fall into the feeding pipe 1708, thus sliding into the conical tube 16. In the rear slide cooling pipe 13, dry ice evaporates instantly upon encountering high temperatures, generating cold air. This cold air circulates within the cooling pipe 13, effectively cooling the stationary mold plate 1. This solves the problem of existing injection molding processes where high temperatures after processing can easily cause accidental burns to operators, posing a safety hazard. It also addresses the issue of long cooling times for the ball valve body after injection molding, leading to slow molding and reduced processing efficiency. The storage box 1701 is insulated, and dry ice pellets are placed inside. The inner wall of the discharge hopper 1702 is inclined, allowing the dry ice pellets to slide down automatically.

[0036] like Figure 2 , Figure 3 and Figure 5As shown, a first air vent 14 is provided on one side of the static template 1, and a second air vent 15 is provided on the rear surface of the static template 1. A ventilation channel 10 is provided at one end of the first air vent 14. A heat dissipation mesh plate 11 is fixedly installed between the inner walls of the ventilation channel 10. A connecting cover 12 is fixedly connected to the outer surface of the ventilation channel 10. The other end of the heat insulation pipe 1801 extends into the interior of the connecting cover 12. A one-way valve 1804 is provided on the outer surface of the heat insulation pipe 1801. The heat generated when the injection molding begins is output from the ventilation channel 10 through the cooling pipe 13 and transported to the connecting cover 12 through the heat dissipation mesh plate 11, so that the hot air can enter the heat insulation pipe 1801. By opening the one-way valve 1804, the hot air can only be transported in one direction and cannot flow back.

[0037] like Figure 2 and Figure 3 As shown, a fixed hose 1803 is fixedly connected to the outer surface of the insulation pipe 1801. A fixed frame 19 is fixedly installed on the rear surface of the static template 1. A negative pressure pump 20 is provided between the inner walls of the fixed frame 19. By installing the fixed hose 1803 on the air inlet or outlet of the negative pressure pump 20 according to the needs of air inlet and outlet, the negative pressure pump 20 can be used as a backup. Starting the negative pressure pump 20 can drive the sealing piston 1805 to move, thereby enabling the contact block 1807 to start, thus avoiding the situation where the automatic air pressure is insufficient, causing the blocking slide plate 1706 to be unable to move normally.

[0038] like Figure 3 As shown, a first reinforcing rod 21 is fixedly installed on one side of the static template 1. One end of the first reinforcing rod 21 is fixedly connected to the outer surface of the insulation pipe 1801. A second reinforcing rod 22 is fixedly installed on the rear surface of the static template 1. One end of the second reinforcing rod 22 is fixedly connected to the outer surface of the insulation pipe 1801. Through the supporting effect of the first reinforcing rod 21 and the second reinforcing rod 22, the insulation pipe 1801 can be effectively fixed.

[0039] like Figure 5 and Figure 6 As shown, one end of the L-shaped fixing rod 1703 is fixedly connected to the rear surface of the static template 1, and one end of the feeding pipe 1708 is fixedly connected to the tapered pipe 16. One end of the tapered pipe 16 is fixedly connected to one end of the second air outlet 15. The end of the tapered pipe 16 with a smaller inner diameter is connected to the feeding pipe 1708, and the end with a larger inner diameter is connected to the second air outlet 15, which allows dry ice particles to slide into the cooling pipe 13 under inertial action.

[0040] like Figure 6 and Figure 7As shown, a controller 1704 is provided on the top of the L-shaped fixed rod 1703. The controller 1704 is electrically connected to the electric telescopic rod 1705. The controller 1704 controls the extension length and interval of the electric telescopic rod 1705 so that the connecting port 1709 can accurately correspond to the hopper 1702 and the discharge pipe 1708.

[0041] like Figure 1 and Figure 3 As shown, support rods 2 are welded to the top of the static template 1 near the four corners. Support plates 4 are welded between the tops of the four support rods 2. The tops of the four support rods 2 slide through to the top of the moving template 3. The position of the moving template 3 is limited by the support rods 2 to ensure that the positions of the static template 1 and the moving template 3 correspond.

[0042] like Figure 1 and Figure 2 As shown, the top of the support plate 4 is provided with a multi-stage electric actuator 5, and the bottom of the multi-stage electric actuator 5 is fixedly installed with an mounting plate 8. The bottom of the mounting plate 8 is installed on the top of the moving template 3 by screws. By activating the multi-stage electric actuator 5, the multi-stage electric actuator 5 is extended, thereby driving the moving template 3 to press down until it is in contact with the top of the stationary template 1.

[0043] like Figure 1 and Figure 2 As shown, the bottom of the moving template 3 is provided with an upper forming groove 9, and the top of the stationary template 1 is provided with a lower forming groove 7. Molten metal is injected into the upper forming groove 9 and the lower forming groove 7, which enables the ball valve body to be precisely formed.

[0044] like Figure 6 and Figure 7 As shown, a reinforcing block 1707 is fixedly installed on the other side of the storage box 1701. The cross-section of the reinforcing block 1707 is triangular. Through the stable support of the reinforcing block 1707, the blocking slide plate 1706 can slide on its surface, which can prevent one end of the blocking slide plate 1706 from tilting up when sliding.

[0045] The operating method and working principle of this device are as follows: During operation, the ball valve body is formed by injecting molten metal into a mold. This generates significant heat, which is concentrated and transported out from the heat dissipation plate 11 into the insulation pipe 1801. This prevents burns to the operator. The increased temperature within the insulation pipe 1801 increases the air pressure, which flows towards the movable cylinder 1802, creating a negative pressure that pushes the sealing piston 1805 forward. This, in turn, pushes the sliding rod 1806 forward until the contact block 1807 triggers the switch of the controller 1704, opening the valve. The controller 1704 is pre-programmed so that each activation of the electric telescopic rod 1705 involves a fixed period of time. The reciprocating extension and retraction, via the electrical connection between controller 1704 and electric telescopic rod 1705, causes controller 1704 to activate electric telescopic rod 1705 to extend and retract. During this time, electric telescopic rod 1705 pulls and extends the blocking slide plate 1706. By matching the position and inner diameter of the round hole at the bottom of hopper 1702, connecting port 1709, and discharge pipe 1708, the blocking slide plate 1706, when extended forward, blocks the plate between hopper 1702 and connecting port 1709. When retracted, it allows dry ice particles in storage box 1701 to pass through connecting port 1709 and fall into discharge pipe 1708, then slide into conical tube 16, and finally into cooling pipe 13. When the dry ice encounters a high temperature, it instantly evaporates, generating cooling energy. Cool air circulates within the cooling pipe 13, effectively cooling the stationary mold plate 1. Heat generated during injection molding is output through the ventilation channel 10 via the cooling pipe 13, transported through the heat dissipation mesh 11 to the connecting cover 12, allowing hot air to enter the insulation pipe 1801. By opening the one-way valve 1804, hot air can only flow in one direction and cannot flow back. The fixed hose 1803 is installed on the inlet or outlet of the negative pressure pump 20 as needed. The negative pressure pump 20 can then be used as a backup. Starting the negative pressure pump 20 will drive the sealing piston 1805, thereby activating the contact block 1807. This prevents insufficient air pressure from the automatically supplied air from causing the blocking slide plate 1706 to malfunction. The supporting function of the first reinforcing rod 21 and the second reinforcing rod 22 effectively fixes the insulation pipe 1801. The end of the tapered pipe 16 with a smaller inner diameter is connected to the discharge pipe 1708, and the end with a larger inner diameter is connected to the second air outlet 15. The controller 1704 controls the extension and retraction length and interval of the electric telescopic rod 1705, so that the connecting port 1709 can accurately correspond to the discharge hopper 1702 and the discharge pipe 1708. The position of the moving template 3 is limited by the support rod 2 to ensure that the positions of the stationary template 1 and the moving template 3 correspond. By activating the multi-stage electric push rod 5, the multi-stage electric push rod 5 extends, thereby driving the moving template 3 downward until it is in contact with the top of the stationary template 1. The molten metal is injected into the upper forming tank 9 and the lower forming tank 7.By reinforcing the stable support of block 1707, the blocking slide 1706 can slide on its surface, preventing one end of the blocking slide 1706 from lifting up during sliding.

[0046] The wiring diagrams of the multi-stage electric actuator 5, controller 1704, electric telescopic rod 1705, and negative pressure pump 20 in this invention are common knowledge in the field, and their working principles are known technologies. The appropriate model is selected according to actual use. Therefore, the control methods and wiring arrangements of the multi-stage electric actuator 5, controller 1704, electric telescopic rod 1705, and negative pressure pump 20 will not be explained in detail.

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.
