Description

  The present invention comprises a mold having temperature control means, in particular, a mold having a mold surface that defines a cavity, and a temperature control means main body block that is mounted on the mold and adjusts the temperature of the mold. The present invention relates to a mold provided with temperature control means.

  In a die casting machine that performs metal or other die casting, there is known a temperature control mechanism that adjusts (mainly cools) the temperature of a mold using a temperature control medium such as cooling water in order to control the temperature of the mold. Here, a conventional configuration using cooling water as a temperature control medium will be considered.

In the conventional temperature control mechanism of the mold, the cooling water is circulated through a plurality of cooling holes drilled in the mold. For this purpose, a cooling pipe having an outward path and a return path is attached to the cooling hole, and cooling is performed. A water supply hose is connected to the forward path of the pipe, and a drainage hose is connected to the return path. The other end of the water supply hose is connected to the water supply manifold, and the other end of the drainage hose is connected to the drainage manifold. After the cooling water supplied from the water supply manifold circulates through the cooling holes of the mold through each cooling pipe, It is collected in a drainage manifold and drained (for example, Patent Document 1 below).

First and second openings provided on the outer surface of the temperature control means main body block, respectively communicating with the first and second temperature control medium passages and functioning as supply ports or discharge ports for the temperature control medium, respectively. And the structure including was adopted.

  In the above configuration, a temperature control pipe is inserted into each of a plurality of bottomed holes of a mold simply by attaching temperature control means to the mold, and the temperature control medium can be circulated. Because it is not used, the structure is simple and inexpensive, it does not require troublesome work such as attaching and detaching a hose to each temperature control pipe, it is easy to handle, can greatly improve the operation efficiency, and may cause failure.

The mold 200 is mounted on a die casting machine (not shown) via a known mounting mechanism.

  The temperature control pipe 300 is configured by accommodating an inner pipe 301 that functions as an outward path of a temperature control medium (for example, cooling water) in an outer pipe 302 having an inner diameter slightly larger than the outer diameter of the inner pipe 301. The space between the inner pipe 301 and the outer pipe 302 functions as a return path for the temperature control medium. O-rings 303, 303... Are mounted at appropriate positions on the outer periphery of the outer pipe 302 in order to ensure watertightness with the bottomed hole 202 of the mold 200.

  1 and 2, only one temperature control pipe 300 is shown, but actually, the mold 200 has a plurality of bottomed holes 202 provided at appropriate positions satisfying the temperature control conditions. It is arrange | positioned in the position corresponding to. FIG. 3 to be described later shows a structure of three lines.

  Of the three substrates 110, 120, and 130, the central substrate 110 has two openings that constitute the supply / discharge unit for the temperature control medium, that is, the supply port 111 and the discharge port 112. Yes.

  The supply port 111 and the discharge port 112 communicate with each other by the structure shown in FIGS. 2 and 3, and a temperature control medium (cooling water or the like) can be supplied from the supply port 111 and discharged from the discharge port 112. it can.

  Here, the internal structure of the temperature control mechanism 100 will be described in detail with reference to FIGS. 3 and 2.

  FIG. 3 shows the substrates 110, 120, and 130 of the temperature control mechanism 100 in an exploded state. In the center of FIG. 3, the substrate 110 is shown as viewed from the direction of arrow A in FIGS. As shown in FIGS. 1 and 2, the substrate 110 has a T-shaped cross section, and the substrates 120 and 130 are attached to both sides of a T-shaped leg, thereby blocking the temperature control mechanism 100. A shape is defined. The board | substrates 110-120-130 shall be couple | bonded through screwing using the volt | bolt etc. which are not illustrated etc. or another suitable structure.

  The supply port 111 and the discharge port 112 described above are perforated at the top of the substrate 110. As shown in FIG. 2, the supply port 111 and the discharge port 112 are perforated so as to face the mounting surfaces of the substrates 120 and 130, respectively.

  The left side of FIG. 3 shows the substrate 120 removed from the substrate 110 as viewed from the direction of arrow B in FIGS. 1 and 2. On the mounting surface of the substrate 120 to the substrate 110, continuous notches (recesses) 121, 122, and 123 are formed in a shape as illustrated. The portions of the notches 121, 122, and 123 function as an outward path of a temperature control medium (cooling water or the like) in this embodiment.

  In parts other than the notches 121, 122, and 123, the substrate 120 and the substrate 110 are in close contact with each other in a watertight state. If necessary, a gasket material may be interposed between the substrate 120 and the substrate 110 (the same applies between the substrate 130 and the substrate 110 described later).

  The cutouts 123 are provided at predetermined positions as many as the required number of temperature control pipes 300, and the cutouts 123 and the cutouts 121 are connected to each other through the cutouts 122.

  When the substrate 120 is attached to the substrate 110, the notch 121 of the substrate 120 communicates with the supply port 111 as shown in FIG.

  Further, on the mounting surface of the substrate 120 of the substrate 110, a recess 113 is cut at a position corresponding to the notch 123 of the substrate 120 and communicating with the notch 123, and a through hole 114 is formed in the center thereof.

  As shown in FIG. 2, the inner pipe 301 of the temperature adjustment pipe 300 is mounted in the through hole 114. That is, the bush 304 is fixed to the rear end of the inner pipe 301 by fitting, welding, bonding or other methods. The outer diameter of the bush 304 is sized to be accommodated in the recess 113 of the substrate 110. By accommodating the bush 304 in the recess 113 and fixing it by a sealant bonding or brazing method, the inner pipe 301 is fixed to the substrate. 110 is fixed. A watertight material such as an O-ring or a gasket is inserted between the bush 304 and the recess 113 as necessary.

  On the other hand, on the right side of FIG. 3, the substrate 130 removed from the substrate 110 is shown as viewed from the direction of arrow A in FIGS. In this embodiment, the substrate 130 is provided with notches 131 and 132 and a through-hole 133 that communicate with each other so as to function as a return path for a temperature control medium (cooling water or the like).

  Among these, the notch 131 communicates with the discharge port 112 of the substrate 110. Further, the through-hole 133 communicated through the notch 131 and the notch 132 is provided at the same size and the same position as the through-hole 114 of the substrate 110, and as shown in FIG. 301 is accommodated.

  Further, a notch 134 is provided on the mounting surface of the substrate 130 with respect to the mold 200 so as to be coaxial with the through-hole 133. The rear end of the outer pipe 302 of the temperature adjustment pipe 300 is fixed to the notch 134. That is, a bush 306 is fixed to the rear end portion of the outer pipe 302, and the outer pipe 302 is fixed to the substrate 130 by fixing the bush 306 in the notch 134 by a method such as adhesive bonding or brazing. Fixed against.

  By connecting the substrate 120 and the substrate 130 to the substrate 110 with the inner pipe 301 mounted on the substrate 120 and the outer pipe 302 mounted on the substrate 130, the communication from the supply port 111 to the discharge port 112 of the temperature control mechanism 100 is established. The completed temperature control medium passage is completed.

  The temperature control mechanism 100 configured as described above can be attached to the mold 200 as shown in FIG. The mold 200 has a mold surface 201 that defines a cavity for die casting, and is mounted on a die casting machine (not shown) together with the temperature control mechanism 100.

  When the temperature control mechanism 100 is attached to the mold 200, the temperature control pipe 300 is inserted into the plurality of bottomed holes 202 drilled in the mold 200. The bottomed hole 202 is drilled with a clearance slightly larger than the outer diameter of the outer pipe 302 of the temperature control pipe 300, and the bottomed hole 202 and the outer pipe 302 are sealed in a watertight state by an O-ring 303. .

  In the above-mentioned mounting state, a supply hose for supplying a temperature control medium (cooling water or the like) to the supply port 111 and a single discharge hose to the discharge port 112 are mounted, and pressure is applied by a pump (not shown). Thus, the temperature control medium is circulated through the temperature control medium passage communicating from the supply port 111 to the discharge port 112, and thereby the temperature of the mold 200 can be managed.

  The first and second paths (outward / return paths) through which the temperature control medium circulates are as indicated by arrows in FIG. Among these, the outward path continues from the supply port 111 to the notch 121 to the notch 122 to the notch 123 to the inner pipe 301 to the bottomed hole 202. Further, the return path continues from the inside of the bottomed hole 202 to the outer pipe 302 to the through hole 133 to the notch 132 to the notch 131 to the discharge port 112.

  According to the above configuration, it is not necessary to connect the supply hose and the discharge hose of the temperature control medium to each temperature control pipe as in the prior art.

  Therefore, it is not necessary to prepare a large number of supply / discharge hoses, and the substrates 110, 120, and 130 of the temperature control mechanism 100 can be easily formed from a material such as metal, and the configuration is simple and inexpensive. Moreover, even when it is necessary to attach / detach the supply hose and the discharge hose for maintenance of the temperature control mechanism 100, it is not necessary to attach / detach many hoses, and only one supply hose and the discharge hose are attached / detached at most. Therefore, the operation efficiency is remarkably improved.

  In addition, since a large number of supply / discharge hoses are not used, the durability and reliability of the entire mechanism can be greatly improved. In the conventional structure, since a large number of supply / discharge hoses are used, there is a possibility that failure or breakage occurs in each hose, and the trouble of inspection and the like is not stupid. However, according to this embodiment, at most one hose is used. Only the supply hose and the discharge hose are provided, the number of places where there is a possibility of failure is remarkably reduced, the reliability of the mechanism can be greatly improved, and the inspection becomes very easy.

  In Example 1 described above, the three substrates 110, 120, and 130 are used for the basic structure of the temperature control mechanism 100. However, this structure can be further simplified as shown in this embodiment.

  The configuration of this embodiment is shown in FIGS. FIGS. 4 to 6 correspond to FIGS. 1 to 3, respectively, and the same reference numerals are used for the same or corresponding members, and detailed descriptions thereof are omitted except for members that need to be specifically described. It shall be.

  As is clear from the comparison of FIGS. 4 to 6 with FIGS. 1 to 3, the structure of this embodiment is a structure in which the structure provided on the substrate 130 is provided in the mold 200 and the substrate 130 is omitted, or the embodiment. It can be said that this is a structure in which one substrate 130 and the mold 200 are integrated.

  Further, in this structure, since the return path of the temperature control medium is formed at the boundary surface between the substrate 110 and the mold 200, unlike the temperature control pipe 300 of the first embodiment, the outer pipe 302 is not required. It is comprised only by the pipe 301 inside.

  FIG. 4 shows a state in which the temperature control mechanism 100 is removed from the mold 200 as in FIG. 1, and the portion of the substrate 130 shown in FIG. 1 is removed as shown, and only the pipe 301 is removed from the substrate 110. It protrudes. The structures of the substrate 110 and the substrate 120 are the same as those in the first embodiment.

  As shown in FIGS. 5 and 6, the structure provided on the substrate 130 in Example 1 is provided on the temperature control mechanism mounting surface of the mold 200 except for the structure necessary for the outer pipe 302.

  That is, notches 231 and 232 are cut on the temperature control mechanism mounting surface of the mold 200 as shown in FIG. 6, and the notch 232 connects the notch 231 and the bottomed hole 202.

  Further, the temperature control mechanism mounting surface of the mold 200 is processed with a step 240 so as to receive the T-shaped structure of FIG.

  In the case of this embodiment, since the return path of the temperature control medium is formed at the boundary surface between the substrate 110 and the mold 200, the contact portion between the mold 200 and the substrate 110 needs to have a close-contact structure having water tightness. For this reason, the mold 200 and the substrate 110 are bonded by a structure such as bonding with a sealant or fastening together with a bolt or the like through a gasket cut out in the shape of the return path of the temperature control medium.

  When the temperature control mechanism 100 is coupled to the mold 200, two paths (outward / return paths) of the temperature control medium of the present embodiment are formed as shown in FIG.

  The outgoing path of the temperature control medium is the same as that of the first embodiment, and continues from the supply port 111 to the notch 121 to the notch 122 to the notch 123 to the pipe 301.

  On the other hand, the return path of the temperature control medium continues from the tip of the pipe 301 to the opening of the bottomed hole 202, and communicates with the discharge port 112 through the notches 232 and 231.

  With the configuration as described above, the present embodiment does not use a large number of hoses as in the first embodiment. Therefore, the configuration is simple and inexpensive, the handling is easy, the operation efficiency is remarkably improved, the reliability is high, and the inspection is performed. In addition to the effects such as being easy, the number of parts can be further reduced.

  Moreover, since the outer pipe of the first embodiment can be omitted, the temperature adjustment medium can be directly passed through the bottomed hole 202 of the mold 200, and the temperature adjustment (for example, cooling) efficiency can be greatly improved.

  Although two embodiments have been described above, the following modifications can be considered with respect to the structure of each of the above embodiments.

  The above-described allocation of the temperature control medium forward / return is merely an example, and the direction in which the temperature control medium flows may be opposite to that described above. In the case of reversing the forward path / return path with the above embodiment, the functions of the two openings of the supply port 111 and the discharge port 112 are naturally reversed.

  The material of each part is arbitrary, and it goes without saying that any material other than metal may be used for each part depending on required characteristics such as heat conduction. Further, the inner / outer pipes constituting the temperature control pipe do not necessarily have rigidity, and the inner / outer pipes may be made of a deformable flexible material such as rubber or plastic. Thus, even when a large number of temperature control pipes are provided, the problem of dimensional errors can be avoided, and problems such as the inability to attach the temperature control mechanism even if there are some errors can be solved. In addition, even when each bottomed hole cannot be drilled in parallel (or does not want to be drilled) according to the shape of the mold surface, etc., each temperature control pipe can be made of a flexible material. The pipe can be accommodated in each bottomed hole without any problem.

  In the above embodiment, the notches (121, 122, 123, 131, 132, etc.) constituting the temperature control medium passage are mainly provided on the temperature control mechanism mounting surface of the substrates 120 and 130 or the mold 200. Illustrated. However, the notches constituting these temperature control medium passages may be provided at the boundary surface between the substrates constituting the temperature control means or the boundary surface between the substrate and the mold, and any one of these boundary surfaces is processed. Needless to say, it can be defined by.
