Technical Field

[0001] The utility model relates to the technical field of pipeline connection, in particular to a cooling pipeline connection device for an injection mold. Background Art

[0002] At present, molds are various molds and tools used in industrial production to obtain the desired products by injection molding, blow molding, extrusion, die casting or forging molding, smelting, stamping and other methods. In short, molds are tools used to make molded objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the object by changing the physical state of the molded material. It is known as the "mother of industry".

[0003] Generally, the molded objects in the injection mold need to be cooled after injection. However, the common cooling pipe connection devices cannot enable the staff to quickly install and disassemble them. In addition, the connection points between the pipes are all connected by threads, which may rust over a long period of time, thus affecting the staff's subsequent maintenance and disassembly of the pipes. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides an injection mold cooling pipe connecting device to solve the problem mentioned in the above background technology that the molded object in the general injection mold needs to be cooled after injection molding, but the common cooling pipe connecting devices cannot enable the staff to quickly install and disassemble them, and the connection points between the pipes are all connected by threads, which may rust over a long period of time, thereby affecting the subsequent maintenance and disassembly of the pipes by the staff.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an injection mold cooling pipe connecting device, comprising a first pipe, a first connecting plate is fixedly installed on one side end face of the first pipe, the first connecting plate is circular in shape, the front end of the first pipe is connected to the second pipe, the front end of the second pipe is connected to the second connecting plate, the second connecting plate is circular in shape, four positioning holes are opened on the first connecting plate and the second connecting plate, the four positioning holes are arranged in a circular array on the first connecting plate and the second connecting plate, and positioning bolts are inserted into the four positioning holes.

[0006] By adopting the above technical solution, the first pipe and the second pipe are connected by inserting the positioning bolt into the positioning hole formed on the first connecting plate and the second connecting plate. Then, when the pipe needs to be disassembled, the positioning bolt is first taken out from the positioning hole, and then the limit block is pressed downward so that the spring drives the limit block to contract. Then the limit block will cancel the limit between the first pipe and the second pipe, thereby facilitating the staff to disassemble and install it.

[0007] Preferably, a first connecting tube is provided on the front end surface of the first connecting plate, a baffle is provided inside the first connecting tube, and first grooves are provided on both upper and lower end surfaces of the first connecting tube.

[0008] By adopting the above technical solution, the baffle plate arranged in the first connecting plate can better limit the second connecting pipe, and the first grooves opened at the upper and lower ends of the first connecting pipe facilitate the limiting plate to limit the connection.

[0009] Preferably, a slot is provided in the second pipe, a second connecting pipe is fixedly installed in the slot, the diameter of the second connecting pipe is smaller than that of the first connecting pipe, and the first connecting pipe is inserted in the slot.

[0010] By adopting the above technical solution, the first connecting pipe provided at the front end of the first pipe can be better inserted into the slot provided in the second pipe, thereby better connecting the first pipe and the second pipe.

[0011] Preferably, three springs are fixedly installed on the upper and lower end surfaces of the second connecting pipe, and limiting plates are fixedly installed on the three springs. The shape of the limiting plates is trapezoidal. Second grooves are provided on the upper and lower end surfaces of the second pipe, and the diameter of the limiting plates is smaller than that of the first groove and the second groove.

[0012] By adopting the above technical solution, the first connecting pipe on the first pipe is inserted into the slot opened in the second connecting pipe. Then, because the shape of the limiting plate is a trapezoid, and the inclined surface of the limiting plate is facing the first pipe, when the first connecting pipe on the first pipe is inserted into the slot in the second pipe, the spring arranged at the bottom of the limiting plate will contract. When the first pipe is completely inserted into the slot in the second pipe, the spring arranged at the bottom of the limiting plate will rebound, and then the limiting plate will extend from the first groove and the second groove. Then, because the vertical end of the trapezoid is facing the second pipe, the connected first pipe and the second pipe can be better limited.

[0013] Preferably, a sealing ring is provided in the connection point between the first pipe and the second pipe, and the material used for the sealing ring is rubber material.

[0014] By adopting the above technical solution, a sealing ring is provided at the connection between the first pipe and the second pipe, so that the sealing performance of the pipe connection device can be improved to prevent leakage at the pipe connection.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The injection mold cooling pipe connecting device connects the first pipe and the second pipe by inserting the positioning bolt into the positioning hole provided on the first connecting plate and the second connecting plate. When the pipe needs to be disassembled, the positioning bolt is first taken out from the positioning hole, and then the limit block is pressed downward so that the spring drives the limit block to contract. Then the limit block cancels the limit between the first pipe and the second pipe, so as to facilitate the staff to disassemble and install it.
