Technical Field

[0001] This utility model relates to the technical field of injection molding machine guide pillars, specifically to an anti-breakage structure for injection molding machine guide pillars. Background Technology

[0002] Tie rods are rod-shaped components installed on machinery or buildings to provide traction. Their principle is to balance the sliding of the mold plate and withstand the tension caused by mold clamping. They are an important component in the injection molding machine industry. In the mold clamping mechanism, the performance of the tie rods directly affects the rigidity and stability of the system; improving the structural characteristics of the tie rods is essential to effectively improve the rigidity and stability of the system.

[0003] When the injection unit operates, the temperature of the gate column rises due to friction. The metal gate column's strength decreases at high temperatures, leading to gate column breakage during injection molding machine operation. Replacing the gate column is time-consuming and labor-intensive, thus affecting the overall production efficiency of the injection molding machine. Therefore, this utility model proposes an anti-breakage structure for injection molding machine gate columns to solve the above problems. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a breakage prevention structure for injection molding machine tie rods, comprising:

[0006] The return channel is formed on the side wall of the gate column, and a set of return channels are symmetrically formed on the side wall of the gate column. The symmetry plane of the two return channels is the same as the symmetry plane of the vertical direction of the gate column. The front and rear ends of the gate column are respectively fixed to the front side plate and the rear side plate of the injection molding machine frame.

[0007] The oil injection hole is located on the base of the injection unit, and the outer end of the oil injection hole is formed with a pipe connection port. The pipe connection port is connected to the lubricating oil adding equipment through a lubricating oil supply pipe, and the inner end of the oil injection hole is connected to the movable hole on the base. The guide column is set through the movable hole.

[0008] Preferably, during actual installation, the height of the return channel decreases sequentially from the front end to the rear end of the return channel.

[0009] Preferably, an oil collection trough is fixedly installed on the rear side plate of the injection molding machine frame. An oil outlet is formed at the lower end of the oil collection trough. The lower end of the oil outlet is connected to a secondary oil return pipe through a pipe connector. The secondary oil return pipe is connected to the main oil return pipe. The lubricating oil flowing out of the main oil return pipe is transported to the oil tank of the lubricating oil adding device by a circulation pump.

[0010] Preferably, an oil-blocking groove is provided at the lower rear end of the goring column.

[0011] Preferably, the rear end faces of the oil blocking groove and the guide column are both located directly above the oil collecting groove.

[0029] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] Please see Figure 1-11 The present invention provides the following three preferred embodiments:

[0031] Example 1

[0032] A breakage prevention structure for a gatepost in an injection molding machine includes a return channel 1 and an oil injection port 2. The return channel 1 is formed on the side wall of the gatepost 3, and a set of return channels 1 are symmetrically formed on the side wall of the gatepost 3. The symmetry plane of the two return channels 1 is the same as the symmetry plane of the gatepost 3 in the vertical direction. The front and rear ends of the gatepost 3 are respectively fixed to the front and rear side plates of the injection molding machine frame 4. The oil injection port 2 is formed on the base 5 of the injection unit, and the outer end of the oil injection port 2 is formed with a pipe connection port 6. The pipe connection port 6 is connected to a lubricating oil adding device through a lubricating oil supply pipe, and the inner side of the oil injection port 2... The end is connected to the movable hole on the base 5. The gate column 3 passes through the movable hole. By setting the anti-breakage structure of the injection molding machine gate column, which is composed of the return groove 1 and the oil injection hole 2, lubricating oil is added to the side wall of the gate column 3 through the oil injection hole 2. The lubricating oil improves the heat dissipation efficiency, and the lubricating oil flowing down the side wall of the gate column 3 can carry away a certain amount of heat. The lubricating oil then flows out along the return groove 1, thereby reducing the temperature of the gate column 3. This effectively prevents the gate column 3 from overheating and reducing its strength, thus effectively reducing the risk of the gate column 3 breaking.

[0033] When the guide column 3 is actually installed, the height of the return groove 1 decreases sequentially from the front end to the rear end of the return groove 1, which makes it easier for the lubricating oil to flow out of the return groove 1 more quickly.

[0034] Example 2

[0035] Based on Embodiment 1, an oil collection trough 7 is fixedly installed on the rear side plate of the injection molding machine frame 4. An oil outlet 8 is formed at the lower end of the oil collection trough 7. The lower end of the oil outlet 8 is connected to a secondary oil return pipe 10 through a pipe connector 9. The secondary oil return pipe 10 is connected to the main oil return pipe 11. The lubricating oil flowing out of the main oil return pipe 11 is transported to the oil tank of the lubricating oil adding equipment by a circulation pump. By fixing the oil collection trough 7 on the rear side plate of the injection molding machine frame 4, the lubricating oil flowing out of the return tank 1 can be recovered through the oil collection trough 7, thereby effectively improving the utilization rate of lubricating oil and reducing production costs.

[0036] An oil blocking groove 12 is provided at the lower rear end of the guide column 3. The oil blocking groove 12 and the rear end face of the guide column 3 are both located directly above the oil collecting groove 7 to prevent lubricating oil from flowing along the guide column 3 and dripping down to the middle of the guide column 3.

[0037] Example 3

[0038] Based on Embodiment 2, a filter element is installed in the oil collection tank 7.

[0039] The filter element is composed of a filter ball 13 and an installation tube 14. The filter ball 13 and the installation tube 14 are integrally formed, and the cavity of the installation tube 14 is connected to the inner cavity of the filter ball 13. Filter holes 15 are evenly opened on the side wall of the filter ball 13. The installation tube 14 is threaded to the upper port of the oil outlet 8 to improve the cleanliness of the reused lubricating oil and avoid impurities from affecting the normal operation of the equipment.
