Description

Technical Field

[0001] The utility model relates to the technical field of die-casting machines, in particular to a stackable neutron valve block used in a die-casting machine. Background Art

[0002] With the development of industrial technology, the application fields of plastic products are becoming wider and wider, and there are more and more types of plastic molds for injection molding machines. The shapes of the molds are also different. For some special molds, the product must be on the movable mold when the mold is opened. If there are holes or other patterns, it will definitely not be able to be demolded. Therefore, when designing the mold, there must be a core pulling action to remove the mold iron with holes or patterns. At this time, the product is more likely to fall off.

[0003] At present, in the existing die-casting machines, different numbers of neutrons are required for different molds according to different customer needs, so different numbers of core-pulling valve plates are required. In view of this situation, different numbers of neutron valve plates are often designed. In order to increase versatility, the core-pulling valve plates designed under this method often have more installation ports for oil return to cope with the situation of a large number of core-pulling, but when only one core is used, the other valve ports must be covered with a cover plate; and when the number is large, it is often necessary to increase the number of neutron valve plates, and at this time, the oil circuit needs to be rearranged, which brings great inconvenience to the design, production and installation.

[0004] The Korean invention patent with application number KR1020110102503 discloses a flow superposition system for controlling a variable displacement hydraulic pump. The invention includes a control valve assembly, which includes a flow summing node and multiple control valves. The flow summing node is connected to the input port of the variable displacement pump. When the fluid flow increases, the variable displacement pump and the flow summing node are opened, and the fluid from the flow summing node to multiple hydraulic actuators increases. Such actuation can apply the variable displacement pump and variable pressure to the control input port, and increase the response by sending the variable displacement pump into the fluid supply pipeline to increase the amount of fluid used to operate each hydraulic actuator to meet the fluid demand. When the invention is applied to the field of injection molding machines and die-casting machines, it is necessary to connect the oil port of the control valve to the oil circuit and block other valve ports with a cover plate. It is not possible to conveniently select and install according to demand, and the oil circuit needs to be re-arranged, which increases the difficulty of installation. Summary of the invention

[0005] The utility model aims to provide a stackable neutron valve block which is used in a die-casting machine and has strong adaptability and is easy to disassemble and assemble.

[0006] In order to solve the above technical problems, the utility model specifically provides the following technical solutions:

[0007] A stackable neutron valve block for a die-casting machine comprises a neutron stacking valve block having an oil circuit, and a function-selected valve block and a transition block connected to the oil circuit on the surface of the neutron stacking valve block.

[0008] Preferably, the upper and lower surfaces of the neutron stacked valve block are respectively provided with oil inlets and outlets connected to the oil circuit, and the oil inlets and outlets on the lower surface are matched. The upper and lower surfaces of the neutron stacked valve block are also provided with threaded holes for stacking connection.

[0009] Preferably, the neutron stacking valve block is provided with a hydraulic reversing valve on the left side, the hydraulic reversing valve is connected to an electromagnetic reversing valve, and the hydraulic reversing valve is connected to the oil circuit. Align the oil inlet and outlet ports and threaded holes of multiple neutron stacking valve blocks, and realize the stacking connection of the neutron stacking valve blocks by installing screws in the threaded holes. At this time, the oil inlet and outlet ports of multiple neutron stacking valve blocks are connected to each other, and the overall control of the oil passage is realized by relying on the hydraulic reversing valve and the electromagnetic reversing valve;

[0010] The structure of the neutron stacking valve block can realize any number of stacking, so as to adapt to different selection and installation of the die-casting machine, enhance the adaptability of the valve block to actual needs, and thus improve the convenience of later maintenance and disassembly and replacement;

[0011] During the production process, since the above-mentioned neutron stacking valve blocks have unified specifications, any number of combinations can be realized, that is, there is no need to prepare a variety of valve blocks with different numbers of core pulling or other functions, thereby realizing the standardization of the die-casting machine assembly valve blocks and reducing the overall manufacturing cost of the die-casting machine.

[0012] Preferably, the neutron stacking valve block is provided with grooves on the front and rear sides, and the horizontal end of the groove is provided with threaded holes for stacking connection. The threaded holes in the groove facilitate the installation of fixing screws, so that each stacked neutron stacking valve block can be fixed, thereby improving the firmness of the stacking state and greatly reducing the risk of oil leakage.

[0013] Preferably, the neutron stacked valve block is detachably connected with a valve block pad on the right side. The valve block pad can facilitate adjustment of the installation position of the neutron stacked valve block and improve its matching degree on the die casting machine.

[0014] Preferably, the neutron stacked valve block further comprises a flange clamp and an oil pipe joint, and the oil pipe joint is installed at the oil inlet and outlet through the flange clamp. The oil pipe joint is connected to an oil pipeline, and the flange clamp is used to fasten the oil pipe joint at the oil inlet and outlet to reduce the possibility of oil leakage and pollution of the environment.

[0015] Preferably, the function-option valve block is detachably connected to the bottom of the neutron stacking valve block, and the function-option valve block can be stacked with the neutron stacking valve block in the same direction.

[0016] Preferably, the function selection valve block is connected to a solenoid valve on the side. The function selection valve block can be stacked in the same direction in the same form as the neutron stacking valve block, and cooperate with the solenoid valve to realize oil control while further enhancing the adaptability of the valve block to the die casting machine.

[0017] Preferably, the neutron stacked valve block is provided with an installation groove on the periphery of the oil inlet and outlet on the lower surface, and an O-ring for sealing is provided in the installation groove. The provision of the O-ring enables adjacent neutron stacked valve blocks to fit closely on the stacked surface, preventing vibration interference from causing the sealing of the inlet and outlet oil ports, reducing the risk of oil leakage, and also relatively reducing the interference of adjacent neutron stacked valve blocks on the stacked surface, thereby protecting the valve blocks and reducing maintenance costs.

[0018] Compared with the prior art, the utility model has the following beneficial effects:

[0019] The utility model sets the passage of oil inlet and outlet, so that multiple valve blocks can be stacked arbitrarily, and core pulling can be increased or reduced according to needs, which is convenient for selection and installation, and also convenient for after-sales maintenance and replacement; it realizes the standardization of stacked valve blocks, there is no need to prepare multiple valve blocks, reduces stocking, and reduces the cost of the machine; the opening of the groove facilitates the stacking and connection of multiple neutron stacked valve blocks, and improves the stacking stability; the valve block pad is convenient for adjusting the position of the neutron stacked valve block, and improves adaptability; the O-ring can prevent the possibility of oil circuit leakage after the valve blocks are stacked, and also reduces assembly interference and wear.
