Description

Technical Field

[0001] This utility model relates to the field of mold equipment, specifically a guiding device for injection molds. Background Technology

[0002] Injection molding is a method of shaping industrial products; products are usually made using rubber injection molding and plastic injection molding; injection molding can also be divided into injection molding compression molding and die casting.

[0003] Existing injection molds require the moving mold to close, and during use, the mold needs to be positioned by a positioning rod. Over time, the positioning rod wears down, resulting in reduced positioning accuracy and making it impossible for the mold to close completely. During injection, raw materials can easily overflow through the misaligned gaps, posing a certain safety hazard and wasting materials. Therefore, there is an urgent need for a device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a guiding device for injection molds to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a guiding device for injection molds, comprising a fixed mold and a moving mold, wherein an injection tube is fixedly embedded in the top of the moving mold, a positioning rod is fixedly fixed in the top of the fixed mold, the positioning rod movably passes through the moving mold, an indicator light is fixedly installed on one side of the fixed mold, hydraulic rods are fixedly installed on both sides of the fixed mold, the top of the hydraulic rods is fixed at the side of the moving mold, a slot is formed inside the moving mold, and an indicator mechanism for conveniently indicating positioning failure is provided in the top of the fixed mold, the indicator mechanism being located inside the slot.

[0006] Preferably, the prompting mechanism includes a first fixed post and a pressure switch. The first fixed post is welded and fixed to the top of the fixed mold. The first fixed post is movably inserted into the cavity. There is a gap between the outer side of the first fixed post and the inner sidewall of the cavity. The pressure switch is embedded and fixed to the outer side of the first fixed post. If the positioning is off during use, the moving mold will move off, causing the inner sidewall of the cavity to squeeze the pressure switch. This causes the prompting light to be activated by the pressure switch, thereby prompting the operator that the positioning is inaccurate and that maintenance or replacement is required.

[0007] Preferably, several pressure switches are provided, all of which are electrically connected to the indicator lights.

[0008] Preferably, the prompting mechanism includes a second fixed post, a thin tube, a control switch, a rubber tube, an extrusion block, and a float. The second fixed post is fixed to the top of the fixed mold and movably inserts into the slot. The second fixed post is a hollow post. The rubber tube is bonded to the upper and lower sides inside the second fixed post. The thin tube is embedded and fixed to the top of the second fixed post. The control switch is embedded and fixed to the top of the thin tube. The float is slidably disposed inside the thin tube. The extrusion block is bonded and fixed to the outside of the rubber tube and movably extends to the outside of the second fixed post. During use, when the moving mold shifts, the outside of the extrusion block is extruded, causing the extrusion block to extrude the outside of the rubber tube, injecting the internal rubber oil into the thin tube. This causes the float to move upward along the thin tube until it extrudes the control switch, activating the prompt light. This indicates that the moving mold has shifted, requiring only one control switch.

[0009] Preferably, the rubber tube is filled with hydraulic oil.

[0010] Preferably, the lower end of the thin tube is connected to the inside of the rubber tube.

[0011] Preferably, there is a gap between the outer side of the second fixing post and the inner sidewall of the slot, and the control switch is electrically connected to the indicator light.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. If the positioning of this utility model is offset during use, the moving mold will shift, causing the inner wall of the slot to press against the pressure switch. This will activate the indicator light, indicating to the operator that the positioning is inaccurate and that repair or replacement is required. 2. When the moving mold deviates during use, the outer side of the extrusion block is squeezed, causing the extrusion block to squeeze the outer side of the rubber tube, injecting the internal oil of the rubber tube into the thin tube, causing the float to move upward along the thin tube until the extrusion control switch is activated, thus indicating that the moving mold has deviated. Only one control switch is needed. Attached Figure Description

The pressure switch 9 is embedded and fixed to the outer side of the first fixed post 8. There are several pressure switches 9, all of which are electrically connected to the warning light 4. If the positioning is off during use, the moving mold 2 will move off, causing the inner sidewall of the cavity 7 to squeeze the pressure switch 9. This causes the warning light 4 to be activated and lit by the pressure switch 9, thus indicating to the operator that the positioning is inaccurate and that repair or replacement is required. Example 2

[0018] Please see Figure 3-4The prompting mechanism includes a second fixed post 10, a thin tube 11, a control switch 12, a rubber tube 14, a compression block 15, and a float 13. The second fixed post 10 is welded and fixed to the top of the fixed mold 1. The second fixed post 10 is movably inserted into the slot 7 and is a hollow post. The rubber tube 14 is bonded and fixed to the upper and lower sides inside the second fixed post 10. The rubber tube 14 is filled with hydraulic oil. The thin tube 11 is embedded and fixed to the top of the second fixed post 10. The lower end of the thin tube 11 communicates with the inside of the rubber tube 14.

There is a gap between the outside of the second fixing post 10 and the inner wall of the slot 7. The control switch 12 is electrically connected to the indicator light 4. When the moving mold 2 is offset during use, the outside of the extrusion block 15 is extruded, causing the extrusion block 15 to extrude the outside of the rubber tube 14, injecting the oil inside the rubber tube 14 into the thin tube 11, causing the float 13 to move upward along the thin tube 11 until the control switch 12 is extruded, activating the indicator light 4. This indicates that the moving mold 2 is offset. Only one control switch 12 is needed.

[0019] Working principle: If the positioning is off during use, the moving mold 2 will shift, causing the inner wall of the slot 7 to press against the pressure switch 9. This will activate the indicator light 4, indicating to the operator that the positioning is inaccurate and requires repair or replacement. When the moving mold 2 shifts during use, it will press against the outside of the extrusion block 15, causing the extrusion block 15 to press against the outside of the rubber tube 14. This will inject the oil inside the rubber tube 14 into the thin tube 11, causing the float 13 to move upward along the thin tube 11 until it presses against the control switch 12, activating the indicator light 4. This indicates that the moving mold 2 has shifted, and only one control switch 12 is needed.
