Description

Technical Field

[0001] The utility model relates to the technical field of valve moulds, in particular to a valve body forming mould. Background Art

[0002] Valves are control components in fluid delivery systems, with functions such as shutoff, regulation, diversion, backflow prevention, pressure stabilization, diversion or overflow pressure relief. Valves used in fluid control systems come in a wide variety of varieties and specifications, from the simplest shutoff valves to the various valves used in extremely complex automatic control systems. Valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. Valves are also divided into cast iron valves, cast steel valves, stainless steel valves (201, 304, 316, etc.), chrome-molybdenum steel valves, chrome-molybdenum-vanadium steel valves, duplex steel valves, plastic valves, non-standard custom valves, etc. according to the material.

[0003] When the existing valves are cast in one piece, multiple molds are spliced ​​into a valve as a whole. After the raw materials are formed, it is difficult to directly open and remove the mold due to the limitations of the valve mold itself. It is usually necessary to manually separate multiple molds, which leads to difficult, cumbersome and laborious mold removal. At the same time, the valve body mold is different from the molds of other workpieces. In order to ensure that the liquid is completely filled into the cavity inside the valve body during casting, an intermittent casting method is usually adopted. After casting a certain amount of raw materials, the liquid is left to stand and the gravity of the liquid is used to fill the cavity. This leads to low casting efficiency. In view of this, we propose a valve body molding mold. Utility Model Content

[0024] In this embodiment, the automatic control demoulding device 2 includes a control motor 21, which is installed in the casting base 1. The output shaft of the control motor 21 is connected to a large bevel gear 22. The surfaces of the large bevel gear 22 are respectively meshed with a bevel gear 1 23 and a bevel gear 2 24. The ends of the bevel gear 1 23 and the bevel gear 2 24 are respectively connected to a threaded rod 1 25 and a threaded rod 2 26 through a belt drive. The threaded connection has the function of adjusting the position and realizing self-locking at the same time, and the valve mold is split into a plurality of detachable and reorganizable sub-molds, thereby realizing the rapid demoulding of the mold after casting while realizing the casting of the valve. At the same time, each sub-mold has the effect of position self-locking, thereby ensuring the stability of the casting work, achieving the effect of saving time and effort and high efficiency.

[0025] The automatic control demoulding device 2 also includes an adjusting screw 27 and a telescopic rod 28. The end of the adjusting screw 27 is fixedly connected to the end of the large bevel gear 22. The surface of the adjusting screw 27 is connected to the internal thread of the inner plug rod 6. The two ends of the telescopic rod 28 are respectively fixedly connected to the surface of the casting base 1 and the end of the inner plug rod 6. The control motor 21 is started, and the output shaft of the motor rotates through the large bevel gear 22 meshing bevel gear 1 23 and two symmetrically distributed bevel gear 2s 24. By driving the threaded rod 1 25, the threaded rod 26 and the adjusting screw 27 to rotate, the outer valve body 1 3, the outer valve body 2 4, the inner cross bar 5 and the inner plug rod 6 are synchronously moved away from each other, thereby realizing the effect of automatic splitting and the effect of convenient demoulding.

[0027] Example 2

[0028] See also Figure 2 and Figure 4 As shown, the automatic vibration device 7 includes a vibration motor 71, the surface of the vibration motor 71 is installed on the casting base 1, the output shaft of the vibration motor 71 is connected to the rotating shaft 72, and the end of the rotating shaft 72 is fixedly connected to the meshing gear 73, as shown in FIG. Figure 2 As shown, the number of meshing gears 73 is set to two, and they mesh with each other, thereby achieving the effect of two sets of rotating shafts 72 rotating in opposite directions and colliding with each other, thereby achieving the effect of colliding with the bottoms of the two outer valve bodies. The surface of the rotating shaft 72 is fixedly connected with an impact column 74, and the end of the impact column 74 is elastically connected with an impact ball 75 through a spring. The spherical impact block is designed so that it can perform corresponding elastic yielding movement when it contacts and impacts the outer valve body at any angle, thereby achieving the effect of elastic impact. The surface of the rotating shaft 72 is rotatably connected in the casting base 1, and the interior of the impact column 74 is slidably connected with a sliding shaft 76, which is used to limit the movement of the impact ball 75 to ensure its stability during rotation and impact. The end of the sliding shaft 76 is fixedly connected to the impact ball 75, and the output shaft of the vibration motor 71 drives the impact ball 75 elastically connected to the impact column 74 to rotate through the rotating shaft 72. During the rotation, the impact ball 75 elastically impacts the bottom of the valve body mold, and utilizes the resonance generated during the impact to realize the compaction of the raw material inside the mold, thereby promoting the effect of quickly filling the mold cavity with the raw material, thereby achieving the effect of increasing the mold injection rate.

[0029] A feeding hopper 8 is fixedly connected to the top of the casting base 1, and a distribution pipe 9 is fixedly connected to the feeding hopper 8. The raw materials are poured into each distribution pipe 9 through the feeding hopper 8 and flow evenly from the bottom to the inside of the mold. The setting of multiple distribution pipes 9 can achieve large-scale casting while ensuring the uniformity of casting, thereby assisting the raw materials to quickly fill the inside of the mold and improve the casting rate.

[0030] When a valve body molding mold of the utility model is in use, the raw material is poured into each distribution pipe 9 through the discharge funnel 8 and flows evenly into the interior of the mold from the bottom thereof. The valve body mold is composed of an outer valve body 1 3, an outer valve body 2 4, two symmetrically distributed inner cross bars 5 and an inner insert rod 6. During the injection molding of the raw material, by starting the vibration motor 71, the output shaft of the motor drives the impact ball 75 elastically connected to the impact column 74 to rotate through the rotating shaft 72. The impact ball 75 elastically impacts the bottom of the valve body mold during rotation, and the resonance generated during the impact is used to realize the compaction of the raw material inside the mold, thereby promoting the effect of quickly filling the inner cavity of the mold with the raw material, thereby achieving the effect of increasing the injection molding rate of the mold.

After the valve body is cast and formed, start the control motor 21, and the output shaft of the motor rotates through the large bevel gear 22 to mesh the bevel gear 1 23 and the two symmetrically distributed bevel gears 24. The bevel gear 1 23 rotates through the pulley and the belt transmission threaded rod 1 25. When the threaded rod 1 25 rotates, it drives the outer valve body 1 3 and the outer valve body 2 4, which are limited to move only linearly and connected to the surface of the threaded rod 2, to move away from each other. At the same time, the bevel gear 2 24 drives the inner cross bar 5 on the threaded rod 2 26, which is limited to move only linearly and connected to the surface of the threaded rod 2, through the pulley and the belt. Move, the two inner cross bars 5 work relatively apart, and at the same time, the large bevel gear 22 drives the inner insert rod 6 to move upward through the adjusting screw 27, and the outer valve body 1 3, the outer valve body 2 4, the inner cross bar 5 and the inner insert rod 6 work synchronously relatively apart, gradually achieving the effect of automatic splitting, and after waiting for them to be completely disconnected, the valve originally formed inside the mold will automatically detach, and then achieve the effect of convenient demoulding, and split the valve mold into multiple detachable and reassembled sub-molds, and then realize the rapid demoulding of the mold after casting while realizing the casting of the valve, saving time and effort, and high efficiency.
