Description

Technical Field

[0001] The utility model relates to the field of injection molding machine accessories processing and production, in particular to a cooling water pipe regulating device. Background Art

[0002] The cooling water pipe of the COMBI-M injection molding machine is an important component in the cooling system, transferring the internal heat to the outside and playing a role in heat exchange. Figure 1 As shown, one end of the water pipe 2 is connected to the medium plate 1, and the other end is fixed in the bottom tank chain 4. At the same time, the joint at the other end of the water pipe is fixed on the medium plate 1 to fix the water pipe 2. Since the positions of the tank chain 4 and the medium plate 1 are fixed, the requirements for the length of the water pipe 2 are relatively high. If the length is short, it cannot be connected to the tank chain 4 and the medium plate 1, resulting in the water pipe 2 being scrapped; if the length is long, it will be accumulated between the tank chain 4 and the medium plate 1, resulting in a waste of resources.

[0003] Moreover, there will inevitably be certain errors in the actual length of products produced by suppliers, which will lead to different lengths of water pipes. There will be deviations between the actual installation state and the ideal installation state during simulation, which will cause the water pipes to be subjected to greater tensile stress during the bending process in the tank chain, generating friction, and finally causing wear and rupture of the water pipes, or even damage to the tank chain. Utility Model Content

[0004] The utility model aims to provide a cooling water pipe regulating device, which realizes switching and regulating for water pipes of different lengths by adding a switching structure, thereby solving the problem of short water pipe life caused by inconsistent water pipe lengths.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a cooling water pipe regulating device, comprising a fixed tank chain and a medium plate, the medium plate is provided with a plurality of water pipe joints for connecting with water pipes, the water pipe is a split structure, comprising a first water pipe connected with the medium plate at one end and a second water pipe connected with the tank chain at one end, the first water pipe and the second water pipe are connected by a transfer structure;

[0006] The transfer structure includes a frame and a hollow hard pipe slidably connected to the frame. Both ends of the hard pipe are respectively connected to the corresponding first water pipe or second water pipe. Water flows from the first water pipe to the second water pipe via the hard pipe to achieve connectivity of the water pipes.

[0007] According to the utility model, further, the frame has a cavity, a pipe clamp is arranged in the cavity, the pipe clamp has a bayonet, and the hard pipe slides in the bayonet.

[0008] According to the utility model, further, the number of the bayonet sockets corresponds to the number of the water pipe connectors on the medium plate.

[0009] According to the utility model, further, water pipe joints are provided at both ends of the hard pipe, and the outer diameter of the water pipe joints is larger than the inner diameter of the bayonet.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] By designing the water pipe as a split structure and connecting the water pipes at both ends through a transition structure, and by moving the hard pipe in the transition structure to the left or right, the distance between the water pipe connected to it and the corresponding medium plate or tank chain is adjusted, thereby solving the problem of being unable to connect with the medium plate or tank chain due to design deviation of the water pipe or excessive stress after connection, reducing the friction problem of the water pipe, thereby reducing the replacement cost of the water pipe and tank chain damaged by wear in the later use process, and at the same time increasing the rationality and adjustability of the cooling water pipe installation.

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] like Figure 2 As shown, a cooling water pipe regulating device is used in the cooling system of an injection molding machine. It includes a tank chain 6 and a medium plate 1 for fixing the water pipe. The medium plate 1 is long and fixed vertically on a fixed surface, and is provided with a plurality of water pipe joints for connecting with the water pipe. The original water pipe is made into a split structure, including a first water pipe 2 and a second water pipe 4, which are connected by a transfer structure. One end of the first water pipe 2 is connected to the water pipe joint on the medium plate 1, and one end of the fourth water pipe 4 is connected to the tank chain 6. The water flows from the first water pipe 2 to the second water pipe 4 via the transfer structure to realize the connection of the water pipes.

[0017] Specifically, the switching structure includes a frame 7 arranged in parallel with the medium plate 1, the frame 7 has a cavity, a pipe clamp 5 is arranged in the cavity, the pipe clamp 5 is long, and a plurality of bayonet holes 51 for the pipeline to pass through are evenly distributed in the length direction, the number of bayonet holes 51 corresponds to the number of water pipe joints arranged on the medium plate 1, and the positions are relative; a hard pipe 3 is arranged in the bayonet hole 51, the hard pipe 3 is a long cylindrical pipe, which can move left and right along the axis of the bayonet hole 51, and water pipe joints with an outer diameter larger than the inner diameter of the bayonet hole 51 are arranged at both ends, which are used to connect with the first water pipe 2 and the second water pipe 4 respectively, and will not fall out of the bayonet hole 51 during the movement and adjustment process. It is explained here that the pipe clamp 5 is a prior art and has a locking function. When the hard pipe 3 is adjusted to a suitable position left and right, the bayonet hole 51 is locked to prevent the hard pipe 3 from moving and affecting the water pipe connection effect.

[0018] Working principle: connect the two ends of the second water pipe 4 to the tank chain 6 and the water pipe joints of the hard pipe 3 facing the tank chain 6 respectively. If the length of the second water pipe 4 is too long or too short, adjust the hard pipe 3 to move left or right along the axis of the bayonet 51 to compensate for the length deviation of the second water pipe 4 and ensure that the second water pipe 4 is connected to the water pipe joint of the hard pipe 3 facing the tank chain 6; then connect one end of the first water pipe 2 to the water pipe joint of the medium plate 1, and the other end of the first water pipe 2 to the water pipe joint at the end of the hard pipe 3. The hard pipe 3 moves left and right along the axial direction of the bayonet 51, which can solve the problem of excessive tensile stress after it is connected with the tank chain 6 and the medium plate 1 due to the length deviation of the water pipe, weaken the interaction of the second water pipe 4 in the tank chain 6 and the tensile stress generated when bending, reduce wear, and increase the service life of the second water pipe 4.

[0019] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
