  The present invention relates to a mold cooling manifold that distributes and supplies a cooling fluid to a plurality of cooling pipes for cooling a mold used for die casting or the like.

In general, a mold used for die casting, injection molding, or the like is provided with a plurality of cooling pipes for cooling the mold. In order to distribute and supply a cooling fluid such as cooling water to these cooling pipes or to collect and collect the cooling fluid from each cooling pipe, a mold cooling manifold is used.
The conventional mold cooling manifold has a main water supply passage and a plurality of branch passages communicating with the main water supply passage, and the plurality of branch passages respectively supply cooling hoses to the corresponding cooling pipes. It is connected by (outward piping) or a discharge hose (return piping) (for example, Patent Document 1).

Utility Model Registration No. 3091865

In the above conventional technique, the following problems remain.
In the conventional mold cooling manifold, since the directions of the plurality of branch channels are fixed, there is a disadvantage that the supply hose or the discharge hose cannot be connected in an arbitrary direction. That is, when connecting a plurality of supply hoses or discharge hoses to the manifold, it corresponds to the case where it is desired to arbitrarily change the connection direction of the supply hoses or discharge hoses connected to the manifold according to the arrangement of the cooling pipes. I couldn't. Therefore, since the connection part of the supply hose and the connection part of the discharge hose are fixed in a certain direction, there is an inconvenience that the degree of freedom of hose handling is low. In addition, since the main water supply channel and the branch flow channel of the manifold are provided by being integrally fixed by welding or the like, there is a problem that disassembly or the like cannot be performed and maintenance is low.

  The present invention has been made in view of the above-described conventional problems, and can arbitrarily change the connection direction of the supply hose or the discharge hose, and has a high degree of freedom in handling these hoses and a mold cooling excellent in maintainability. The purpose is to provide a manifold.

  The present invention employs the following configuration in order to solve the above problems. In other words, the mold cooling manifold according to the first aspect of the invention distributes and supplies cooling fluid to a plurality of cooling pipes that cool the mold, or collects the cooling fluid discharged from the plurality of cooling pipes. A manifold for cooling molds, having a distal end side pipe member having a distal end side opening through which the cooling fluid is introduced or discharged, and a plurality of connections coupled to a proximal end side opening of the distal end side pipe line member A pipe member, and a connecting mechanism for connecting the tip-side pipe member and the connecting pipe member or connecting the connecting pipe members to each other, the tip-side pipe member and the plurality of connecting pipe members However, it has a main flow path that communicates with the opening on the front end side and through which the cooling fluid flows, and the connection pipe member can be connected to a supply hose or a discharge hose connected to the cooling pipe. Hose connection opening communicating with main flow path The connecting mechanism has a peripheral surface, and the connecting mechanism is capable of rotating and removing the connected front-end-side pipe member and the connecting pipe-line member or the connecting pipe-line members relatively in the axial direction. The connection is possible.

  In this mold cooling manifold, the connecting mechanism can rotate and remove the connected distal end side pipe member and the connecting pipe member, or the connecting pipe members relative to each other in the axial direction. Since they are connected, the direction of the opening for connecting the hose can be freely changed by rotating the connecting pipe member with respect to the front-end side pipe member or other connecting pipe member, and for discharging The connection direction of the hose or supply hose can be arbitrarily set. Moreover, since each connection pipe line member is removable, it can be disassembled and maintenance becomes easy.

The mold cooling manifold according to a second aspect of the present invention is the manifold according to the first aspect, wherein the connecting mechanism is provided on one of the connected distal end side pipe member or the outer periphery of the distal end portion of the connecting pipe line member. And the other distal end side pipe member that is provided and connected to the front end side from the male screw part on the outer periphery of the front end part or the seal member that can be in close contact with the inner peripheral surface of the connection pipe member, A female threaded portion that can be screwed into the male threaded portion of one of the connecting conduit members that is provided on and connected to the distal end side pipe member or the proximal end inner peripheral surface of the connecting conduit member, and the proximal end inner peripheral surface And a space portion that is adjacent to the tip end side in the axial direction of the female screw portion and can store the male screw portion.

  For example, a method of connecting the connecting pipe members will be described. First, the distal end portion of one connecting pipe member is pushed into the base end portion of the other connecting pipe member. At this time, the sealing member is in close contact with the inner peripheral surface of the base end portion, thereby preventing cooling fluid from leaking. Next, it inserts, rotating the front-end | tip part of a connection pipeline member further in the base end part of a connection pipeline member. At this time, the male screw portion is screwed into the female screw portion from the outside, and the connecting pipe member is turned into the space formed on the distal end side of the male screw portion to feed the male screw portion. In this state, the male screw part fed into the space part is detached from the female screw part. Axial movement is restricted and positioned.

In addition, in the state where the male thread part is arranged in the space part, the connecting pipe member can be rotated without changing the position in the axial direction, and the connection direction of the supply hose and the discharge hose can be easily adjusted separately. It becomes possible to do. That is, the take-out directions (connection directions) of these hoses are not fixed to each other, and a high degree of freedom in the axial rotation direction is obtained.
When disconnecting the connection pipe members from each other, rotate the connection pipe member in the direction opposite to the direction of attachment while pulling the connection pipe members away from each other, so that the male screw part in the space portion is viewed from the inside. By screwing into the female screw portion and further out beyond the female screw portion, the connection can be easily released, and maintenance is facilitated.

The mold cooling manifold according to a third aspect of the present invention is the first or second aspect of the present invention, wherein the leading end side pipe line member can be connected to the supply hose or the discharge hose and communicate with the main flow path. It has the opening part for a connection in an outer peripheral surface, It is characterized by the above-mentioned.
That is, in this mold cooling manifold, the distal end side pipe member can also be connected to the supply hose or the discharge hose and has a hose connection opening communicating with the main flow path on the outer peripheral surface. A supply hose or a discharge hose can be attached to the pipe member.

The present invention has the following effects.
That is, according to the mold cooling manifold of the present invention, the connected distal end side pipe member and the connecting pipe line member, or the connecting pipe line members can be relatively rotated about the axial direction and removed. Since it has a connecting mechanism that connects it, the direction of the opening for connecting the hose can be changed by rotating the connecting pipe member with respect to the connected leading pipe member or other connecting pipe member. It can be freely changed, and the connection direction of the discharge hose or the supply hose can be arbitrarily set.
Therefore, in the mold cooling manifold of the present invention, a high degree of freedom in handling the supply hose or the discharge hose can be obtained, and excellent maintainability can be obtained.
