Description
Technical field
The present invention relates to a kind of low pressure die casting equipment and method of operating thereof with and used permanent mo(u)ld.
Background technology
For example, CH690356 and EP-A0824983 disclose this low pressure die casting equipment.In known device, the permanent mo(u)ld with two permanent half molds is firmly sandwiched operating means (handling unit), and it also is called manipulator.This installs fixedly connected again conveying device, and this conveying device moves on to next operate portions together with permanent mo(u)ld from an operate portions with manipulator.Manipulator comprises a switching mechanism, utilizes this mechanism, can make permanent mo(u)ld according to the work step open and close.All these work steps are all finished in relevant work portion, for example lock pin, casting, the demoulding, the flushing membrane of clearing up, apply ointment or plaster.In this case, permanent mo(u)ld is carried under closure state usually.Because the big intrinsic counterweight of permanent mo(u)ld so switching mechanism needs high-intensity guide, is used for permanent half mold and corresponding driving member.In addition, manipulator must apply sizable power, so that two permanent half molds are clamped in casting station together, overcomes the liquid metal pressure of rising, prevents that foundry goods from forming flanging.Therefore, in order to apply required closing force and permanent 2 half molds that move relative to each other, manipulator is provided with a high intrinsic counterweight.This counterweight must move by conveying device, and corresponding consumed energy and time.The Machine Design complexity of manipulator is so make and the maintenance cost costliness.Permanent mo(u)ld all must spend certain hour in the each open and close of each operate portions, and the result causes prolong total duration work period, and because of the additional heating of needs work step permanent mo(u)ld will be cooled to below the minimum temperature in some cases.
Except big quality caused the very big inertia of system, lacking flexibility when compression mod or permanent mo(u)ld replacing was the another shortcoming of known device.Permanent mo(u)ld must unload on hand from machinery, the corresponding cost again in assembling.
Summary of the invention
Therefore, the objective of the invention is based on a kind of low pressure die casting equipment of avoiding above-mentioned shortcoming is provided, the Machine Design of manipulator is simple, and the conveying between each operate portions is rapid, and can reduce energy consumption again.
Reaching this purpose is by having the low pressure die casting equipment of claim 1 and 12 characteristics, the permanent mo(u)ld that operation the type low pressure die casting equipment has the method for claim 16 characteristics and has claim 17 characteristics.From relevant claim, illustrate with accompanying drawing in can find out the effective improved place of the present invention.
At least have a casting station and an operate portions is being arranged at least again, lock pin portion preferably, demoulding portion, there is first operating means of at least one first design in the low pressure die casting equipment of spray throwing portion and boshing and/or spray portion and has one second second operating means that designs at least in first scheme of the present invention.First operating means is fit to carry closed permanent mo(u)ld, and second operating means is fit to carry the permanent mo(u)ld that opens wide, and promptly each operating means can both satisfy the effect that regulation is finished.
The operating means of first design is suitable for closure function most and carries closed permanent mo(u)ld.Permanent mo(u)ld preferably is accepted socket joint and is subjected to, and this surrounds closed permanent mo(u)ld at least from both sides, preferably near precision-fit.The two halves of permanent mo(u)ld compress toward each other, and permanent mo(u)ld is closed mechanism and is fixed in the tube, and this mechanism comprises, for example, and at least one closed piston.Because closed piston just is clamped in permanent mo(u)ld and accepts in the tube, short stroke is enough to satisfy, so required machinery expenses is very low.Do not need with first operating means as the means of opening permanent mo(u)ld.In casting cycle, permanent mo(u)ld remains on first operating means.
The operating means of second design is suitable for carrying unlimited permanent mo(u)ld most.Because permanent mo(u)ld need move between the operate portions of handling under the opening-wide state under opening-wide state, thereby has saved the time.Second operating means has two securing members, and each of this securing member is used for fixing half of permanent mo(u)ld, each of the permanent mo(u)ld that is fixed partly in a certain distance apart from one another, and preferably mutual orientation is parallel.According to the method work step that will carry out, unlimited permanent mo(u)ld is transferred to operate portions, is for further processing, and for example transfers to lock pin portion, or in corresponding work step process, for example at the permanent mo(u)ld graphitizing process, still is fixed on the operating means.
Because the optimal design on the function, operating means does not have movable part and the large-scale guide of rigidity, can both finish required basically.In the place of necessity, open/close motion with fixing unlimited and/or direct generation of closing device on the operate portions.
In alternative plan of the present invention, casting station regulation has a clamping device, is used for accepting the permanent mo(u)ld with connector, and this connector merges the two halves of permanent mo(u)ld in casting cycle.In addition, also have a clamping and induction system, this system has an operating means at least, and by the part that is connected with a joggle, be used for accepting permanent mo(u)ld and an operate portions and casting station or and other operate portions between transport permanent mo(u)ld, permanent mo(u)ld shifts or picks up with the clamping device in the casting station again.So permanent mo(u)ld does not fix to clamp on manipulator, but in each operate portions or between them, be moved.Also might use the operating means of first or second design in addition according to the present invention's first scheme.The most handy stationary fit and clamping mode are accepted the fixed clamping device of permanent mo(u)ld, apply required closing force in casting station.No matter because the foundry goods shape is how, the permanent mo(u)ld external dimensions all unify, for example it has preset thickness at least, so the in fact available single-piece manufacturing of clamping device, permanent mo(u)ld inserts wherein, in case of necessity, and with less power clamping.Clamping device needn't move.Insert clamping device and from clamping device, take out by means of the operating means permanent mo(u)ld.In actual fed work, do not need to apply high-intensity power for the two halves that merge permanent mo(u)ld.So for example operating means can have a very light clamping and a conveying device, this device only makes the two halves of permanent mo(u)ld compress mutually lightly, to keep their closure state.For example, used operating means also can be a robot.Generally speaking, fastening durable when operating means needn't adopt as the manipulator that becomes convention so far, because lighter weight that must motion.So it is simple more and cheap at design aspect.
Because permanent mo(u)ld is not fixedly connected to the general operation device that can reach all working portion, so equipment of the present invention can be modular structure fully.In case of necessity, can introduce other operate portions or improve, thereby improve the adaptability of equipment.
In addition, two schemes of the present invention can make up, and for example, by carrying the permanent mo(u)ld of closures or opening-wide state with the operating means of first and second designs, and transfer to the fixed clamping device in the casting station.It is lighter and handier that the operating means of such first design can be made.
In equipment of the present invention, preferably use the standardized permanent mo(u)ld of profile.The permanent mo(u)ld of this pattern has, and for example, comprises the main body and the connector of actual foundry goods mould, for example, be side flange or plate form and connect connector on it, these connectors are arranged like this, be the bulk of permanent mo(u)ld, at a direction in space, be not subjected to the restriction of size of main body at least.Make like this might adopt many different compression mods and not spend design and just can change arbitrarily.The securing member of operating means or device, clamping device and other opening and closing devices can be installed uniform grasping system, and this system makes it and might operate permanent mo(u)ld in required mode, for example forces together in casting cycle, draw back and rotate with cooling etc.So the degree of depth of first operating means acceptance tube is best and the spacing of the two halves connector of closure state permanent mo(u)ld is complementary.In all cases, operating means all will connect a transmission device, and can move independently of each other.Operating means preferably can move along line slideway, and can adjust aspect height.
The effective improved place of the present invention is that permanent mo(u)ld has coding, and this coding can be represented the pattern of permanent mo(u)ld, for example the shape of foundry goods.This can be used on read-out device suitable on each operate portions and reads, and is sent to system control device by corresponding signal, and this device can be central authorities' controls, also can be local control.System control device provides the control course of work required data to operate portions.As example, set the predetermined pressure curve that is fit to the foundry goods shape in casting station, instant transformation power distributes.As example, be to cool off the scheduled time that reaches fixed with compression mod in graphitization portion.As example, in cleaning portion, the permanent mo(u)ld that open wide of mobile nozzle clearing by becoming with compression mod.It is preferably mechanical to encode, and for example, with a socket pin, but also available some other mode produces, for example bar code or data medium.Even fastening durable mechanical coding uses under the recurrent a bit unclean condition of work in casting cycle and also can read reliably.
Each operate portions preferably is equipped with local control device, the local work step of this device control.Relevant deal with data is preferably in CCU input and by local control device request.
