Description

The invention relates to an injection molding intermediate plate comprising a base plate, a spray material inflow channel and at least one connected to the spray material inlet channel spray material distribution channel. The invention also relates to an injection molding machine with such an injection intermediate plate.

The DE 103 25 568 A1 is concerned with a flexible hot runner system that can be operated with various mold assemblies, wherein multiple molds can be supplied with plastic melt either simultaneously or alternatively by an injection unit. Such a hot runner system is used to transfer melt from an injection unit to at least two molds, the two mold halves each form a mold cavity in the closed state, in which a shaped piece is formed. As injection unit, a screw injection molding machine can be used, which takes over both the plasticization of the fed plastic granules and the injection. The described hot runner system for transferring melt from an injection unit of an injection molding machine or an injection molding compounder to at least two molds with a distributor unit comprises a valve system for distributing the melt to the various molds and at least two temperature-controllable hot runner arms with hot runner nozzles via which the melt from the distributor unit is directed to the molds, wherein a support device is provided, which carries the hot runner arms with hot runner nozzles and the distributor unit and is movable relative to the molds and designed to be coupled thereto, and the valve system of the distributor unit is switchable in at least three different positions, so that optionally one the molds or at least two molds can be connected simultaneously with the injection unit.

The object of the invention is to provide an injection molding intermediate plate and an injection molding machine with such an injection intermediate plate, which allows a quick and / or simple change of injection molds of various types and / or different numbers on the injection molding machine.

The object is achieved by an injection molding intermediate plate having a base plate, a spray material inlet channel and at least one connected to the spray material inlet channel spray material distribution channel, wherein the base plate has at least one recess and at least one interchangeable inserted into the recess cassette having at least one Containing line section of the spray material distribution channel.

An injection molding intermediate plate according to the invention is designed to be joined to an injection molding machine which has at least one fixed and / or movable mold clamping plate between a mold half of an injection mold and one of the mold mounting plates. The injection molding intermediate plate thus forms a receiving carrier to which at least one or more mold halves of one or more injection molds is to be fastened. In other words, the injection molding intermediate plate couples the one or more mold halves of the one or more injection molds to the fixed and / or movable mold clamping plate of the injection mold. The injection molding intermediate plate according to the invention is therefore one of the actual injection molding tool, i. separate component from the mold halves. The injection molding intermediate plate thus has an injection mold-side mounting surface which is designed to carry at least one mold half of an injection mold. For this purpose, the injection-molding intermediate plate or its mounting surface may be provided with a person skilled in the art per se known fastening means, such as screws, Aufspannpratzen and / or magnetic plates, which are adapted to secure the at least one mold half of the injection mold on the mounting surface of the injection intermediate plate. The injection molding intermediate plate is then in turn attached to the fixed and / or movable platen of the injection molding machine in proper operation.

The base plate forms the predominantly in size and / or weight predominant part of the injection molding intermediate plate according to the invention. The base plate can therefore be designed so far to absorb a substantial or even the entire proportion of forces and / or stresses occurring during operation of the injection molding machine and in particular by the closing forces of the injection molding machine and / or by the injection forces during the material shooting in the mold cavities of Injection mold occur. In addition, the base plate can form a temperature storage, by the most uniform temperature distribution, in particular can be ensured on the injection mold. In particular, in the case of a plastic injection molding machine, the spray material may preferably be a plastic melt. The spray material, for example, but also be a free-flowing thermoset. The injection molding intermediate plate according to the invention can also be used on machines for powder injection molding, so that the spray material can be, for example, metal powder or ceramic powder. The spray material can also be liquid silicone rubber. If necessary, the spray material can also be water or gas.

In view of the different possible types of spray material, the spray material inflow channels and / or spray material distributor channels according to the invention may in particular be cold runners of a cold runner system or hot runners of a hot runner system. The at least one spray material inflow channel can therefore be a spray material inflow cooling channel or a spraying material inflow hot channel. The at least one spray material distribution channel can therefore be a spray material distributor cold runner or hot material distributor hot runner. In order to enable sprueless injection molding, cold runner nozzles or distributors can be used at temperatures between 60-120 ° C, for example. This can be avoided that the thermoplastic molding compound in the tool or in the injection molding intermediate plate completely cures. The plastic molding compound is then pressed into the cavity during the next injection process. Cold runner nozzles or manifolds generally have a spoiler lip to separate the cured plastic from the plastic during mold opening, while hot runner systems generally provide separation by a locking needle system. In a hot runner system, the sprue system is generally thermally separated from the rest of the tool and heated separately so that the plastic melt in the runner system remains permanently fluid. As a result, there is no solidification of the plastic in the sprue system, in particular in the tool or in the injection intermediate plate, and there is no sprue on the component. Furthermore, longer flow paths can be realized by the hot runner systems, because the pressure loss in the sprue system is not increased by a cooling of the melt and the associated increase in viscosity.

The cassette according to the invention can be embodied in terms of size and / or weight clearly none or lighter than the base plate. Thus, a conversion of the injection molding machine, in particular for changing the number of molds by a mere replacement of cassettes according to the invention is possible without having to replace the entire injection intermediate plate. Thus, compared to the base plate much smaller and / or lighter cassette with less installation effort and possibly also be replaced faster than would be the case if the base plate or the entire injection intermediate plate should be replaced. As a result, a quick and / or simple change of injection molds of different types and / or different numbers on the injection molding machine may be possible.

By several different interchangeable cassettes having different channels, especially hot or cold channels to meet different tasks, you can a single injection molding machine for conventional production with a single injection mold or after a simple change of the corresponding cassette with several injection molds on the same Use injection molding machine.

It is also possible to realize different distances between the injection molding tools or even simple deflections for an off-center injection molding tool.

The injection molding intermediate plate according to the invention can be used for a single and / or for a plurality of injection molding tools, in particular simultaneously on the same injection molding machine. A location of the positioning and the number of injection molds is limited only by the outer dimensions of the base plate of the injection intermediate plate.

The injection molding intermediate plate according to the invention can be combined with magnetic disks as well as for conventional lashing of the injection molding tools. The flexibility, usability of the injection molding machine can be increased and can bring an advantage to the operator of the injection molding machine a more appropriate use of his machinery. The output and the availability of the machine can thus be increased if necessary. Further advantages may be a simple tool technology, color and material equality of different associated components, batch assembly production, reducing hourly rates in a large injection molding machine with multiple injection molds against several individual injection molding machine.

Injection molding tools with different shot weights can be used on the same injection molding machine. In the event of a defect of a single injection mold, it can be replaced individually or temporarily removed and repaired with the advantage that the production does not have to be completely interrupted, i. the injection molding machine with the remaining injection molds and a cartridge inserted into the associated recess of the base plate at the mounting location of the removed injection molding tool without or with a closed spray nozzle. For the operator of the injection molding machine thereby the delivery capability remains. Different numbers of individual components can be manufactured in which, for example, the injection molding machine is switched off for a short time in order to exchange injection molding tools can.

The injection molding intermediate plate according to the invention can also be used in single and multi-component injection molding machines.

The cassette and / or the base plate can have a fastening means, in particular a quick-change fastening device, which is designed to replaceably fix the cassette in the recess of the base plate. In the tool making known to those skilled in the art fasteners or quick-change fasteners can be used according to the invention to easily attach the cassette according to the invention interchangeable in the recess of the base plate can. Thus, individual cassettes can be exchanged, replaced and / or removed or used in a simple manner and / or quickly by a fitter.

The cassette and / or the base plate may include one or more connecting devices configured to couple supply media to be connected to the cassette, in particular water, compressed air, hydraulic fluid and / or electrical energy from the base plate to the cassette when the cassette is inserted into the recess the base plate is inserted. An intermediate plate-side connecting device may be provided in particular on an inner wall of the recess of the base plate and has a corresponding, i. be provided on the connecting device can be coupled to the connection device on the cassette, in particular on a side wall or rear wall of the cassette. In this case, the one connection device or it can couple the plurality of connection devices automatically to the corresponding mating connection device or mating connection devices when the cassette is inserted manually or automatically into the recess of the base plate.

The cassette and / or the base plate may have one or more connection devices which are designed to decouple supply media, in particular water, compressed air, hydraulic fluid and / or electrical energy from the cassette, in particular leak-free when the cassette is out of the recess of the base plate is taken. In this case, one connecting device or the several connecting devices can be automatically disconnected from the corresponding counterconnecting device or from the counter-connecting devices if the cassette is removed manually or automatically from the recess of the base plate. The connecting devices and the counter-connection devices can be designed standardized, in particular such that all cassettes have the same external dimensions, all recesses to the outer dimensions of the cassettes have the same corresponding inner dimensions and / or the connection devices and the mating connection devices always at the same position and location on the cassettes and / or recesses are arranged so that optionally all the cassettes can be inserted and connected in one of a plurality of recesses of the same or different base plates of different injection-molded intermediate plates.

A connecting device formed on the base plate can have a plurality of connection units, in particular a maximum number of injection molds which can be attached at most to the injection molding intermediate plate, each connection unit having a group of connection means for supply media to be connected, in particular water, compressed air, hydraulic fluid and / or electrical energy , Each having an injection mold. For example, a group of connection means may be formed of a combination of electrical connections and supply media coupling means. A group of connection means may be arranged so that they can serve to supply an injection mold and / or a cassette. If necessary unused or unneeded connecting means can be secured by cassette-side end pieces. In the simplest case, a cassette can also be designed as a pure cover cassette, which is designed to fill only the recess in the manner of a placeholder and to complete all open electrical connections and coupling means of supply media.

This is particularly useful when one of several mounted on the injection molding intermediate plate injection molds is removed and the remaining injection molds should continue to be used.

The at least one cassette may have an information carrier characterizing the type of cassette. The information carrier can be designed to be recognized by the cassette merely by way of example by means of a consecutive number or other designation. However, the information carrier can also be designed to contain a multiplicity of properties of the cassette. For example, the information carrier can contain information about the number of gate nozzles on the cassette, the type, number and structure of spray material distribution channels and / or the heating or cooling of line sections. The information carrier as such can be designed in a manner known per se to the person skilled in the art in a constructive manner. For example, the information carrier can be a transponder, in particular an RFID transponder. Alternatively, the information carrier, for example also be formed by mechanical projections and / or notches in a surface of the cassette, which may be encoded. The projections and / or notches can be detected touching or non-contact side of the base plate.

The at least one cassette may have an inlet opening connected to the line section of the spray material distribution channel, in particular sprue bushing and at least one, in particular two or more outflow openings, in particular sprue nozzles, connected to the line section of the spray material distributor channel. In a first embodiment, the cartridge may have a single inflow port and a single outflow port. Between the inlet opening and the outlet opening, the cassette has an unbranching line section. In this case, the spray material distribution channel according to the invention only represents a connecting channel without a branch, which connects the inflow opening with the discharge opening. In this first embodiment, various cassettes may be formed with different positions of the inflow opening and / or the outflow opening, so that different starting positions on the injection-molding plate can be realized by changing various such cassettes of this first embodiment.

In another embodiment, the cassette may have a single inflow opening and, for example, two outflow openings. Between the inflow opening and the two outflow openings, the cassette has a branching line section which separates into two paths. In this case, a spray material distribution channel is formed with one input and two outputs. In this embodiment, the cassette can replace a single cassette with a single runner for supplying a single injection mold to realize two runners by replacing the cassettes so that two separate injection molds can be supplied on the same injection stand. In an analogous manner, cassettes with three or more discharge openings or sprue nozzles for supplying three or more injection molds can be formed on the same injection intermediate plate.

The inlet opening of the cassette may be configured to be connected in the position of the cassette inserted in the recess of the base plate to another line section which is formed in the base plate and which connects the inlet opening of the cassette with a sprue bushing of the base plate. Alternatively, the inlet port of the cassette may be directly formed as a sprue bush, so that an injection unit or plasticizing unit, each of which may comprise, for example, an extruder, may be directly coupled to the cartridge. The base plate can have a passage opening, which allows the injection unit can be coupled through the base plate directly to the cassette inserted into the recess.

The at least one cassette may have a tempering device that is separate from the base plate, in particular a heating and / or cooling device. Thus, the at least one cassette can have fluid channels, in particular water channels, which are connected to inflow channels of the base plate. Depending on whether a heating or cooling device is to be realized, either hot or cold fluid, in particular hot or cold water can be conveyed through the fluid or water channels of the cassette. In order to realize a heating device, as an alternative or in addition to the fluid or water channels, the cassette may also have an electrical heating device which is connected to electrical connections of the cassette, which in turn contact corresponding electrical mating connections of the base plate when the cassette is in the recess of the base plate is used.

The base plate of the injection intermediate plate may have an injection mold side mounting surface adapted to support at least one mold half of an injection mold, the mounting surface of the base plate having the at least one recess into which the interchangeable cassette is inserted. The injection molding intermediate plate thus has an injection mold-side mounting surface which is designed to carry at least one mold half of an injection mold. For this purpose, the injection-molding intermediate plate or its mounting surface may be provided with a person skilled in the art per se known fastening means, such as screws, Aufspannpratzen and / or magnetic plates, which are adapted to secure the at least one mold half of the injection mold on the mounting surface of the injection intermediate plate. The injection molding intermediate plate is then in turn, with its side opposite the mounting surface, fastened to the fixed and / or movable platen of the injection molding machine in operational use.

The invention further relates to an injection molding machine, in particular plastic injection molding machine having at least one fixed and / or movable platen, at least one mold half firmly connected to the mold half of an injection mold and an intermediate mold half and platen intermediate injection molding intermediate plate, as in one or more embodiments according to the invention described, wherein the line section of the spray material distribution channel is adapted to promote a particular supplied via the platen in the cassette supplied spray material flow in a single mold half, or to distribute on two or more mold halves.

In such an injection molding machine, the cassette, in particular depending on their design, one or more discharge openings, in particular sprue nozzles have, which are adapted to be connected to a separate mold half, when the respective cassette inserted into the recess of the base plate and the mold half the injection molding intermediate plate is connected or the mold halves are connected to the injection molding intermediate plate.

The injection molding machine may include an automatic control device for operating the injection molding machine and having a sensor connected to the control device, which is designed to automatically identify the type of cartridge currently being inserted into the injection molding intermediate plate. As a control device, each individual control device can be understood, which is set up for operating the injection molding machine. As a control device, however, a part or a composite of several control devices understood, of which only one is arranged to operate the injection molding machine and a separate part control device is adapted to automatically identify the type of cartridge currently used in the injection intermediate plate over the pickup. The type of cartridge currently used in the injection molding intermediate plate can be determined that an information carrier of the cassette is read by means of the pickup. In this case, the information carrier or the pickup may be designed to recognize the cassette merely, for example, by means of a consecutive number or other name. However, the information carrier or the pickup can also be designed to detect a multiplicity of properties of the cassette. For example, the sensor may read information about the number of nozzles on the cassette, the type, number and structure of the manifold distribution channels and / or the heating or cooling of line sections. The transducer as such can be designed in a manner known to the person skilled in the art in a constructive manner. For example, the sensor may be a reader for a transponder, in particular an RFID transponder. Alternatively, the sensor may for example also be designed to receive and / or evaluate mechanical projections and / or notches in a surface of the cassette, which may be coded. The projections and / or notches can be detected by the sensor on the side of the base plate in a contacting or contactless manner.

The control device of the injection molding machine can be set up to select and / or release an injection molding control program which can be activated by the control device and corresponds to the type of cassette identified by the sensor. Thus, for example, depending on the number of sprue nozzles detected by the picker, the number of currently existing injection molds can be closed, and an injection molding program corresponding to the number of existing injection molds can be selected from a number of held injection molding programs and into the control device to be charged for operating the injection molding machine.

One or more sensors of the injection molding machine can be designed to recognize a functionally reliable, in particular leak-free connection of supply media, in particular water, compressed air, hydraulic fluid and / or electrical energy to the cassette, wherein the control device is connected to the sensors and is set up by the Released control device activatable, the type of cartridge corresponding Spritzgießsteuerprogramm only if the supply media, in particular water, compressed air, hydraulic fluid and / or electrical energy reliable, especially leak-free connected to the cassette. In this case, the cassette and / or the base plate may be equipped with corresponding sensors known to those skilled in the art, which are designed to detect a functionally reliable and / or leakage-free installation state of the cassette in the recess of the base plate. Depending on the functional state of the one or more sensors, a signal characterizing the functionally reliable and / or leakage-free state can be transmitted from the sensors to the control device and further processed there. A functionally reliable connection of the supply media can be understood as a connection type which is known per se to the person skilled in the art and which satisfy the safety regulations applicable there in the respective countries in which the injection molding machine is operated. In Europe, for example, the Directive 2006/42 / EC (Machinery Directive) and the functionally reliable connection of the supply media must be carried out according to this guideline.
