Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to an injection mold positioning device and a structural part. Background Art

[0002] The working principle of the injection molding machine is similar to that of a syringe used for injections. It uses the thrust of a screw or a plunger to inject the plasticized molten plastic into a closed mold cavity, and after solidification and shaping, the finished product is obtained.

[0003] Its operation steps are: first, add granular or powdered plastic into the barrel, and make the plastic molten through the rotation of the screw and the heating of the outer wall of the barrel. Then, the machine closes the mold and moves the injection seat forward, so that the nozzle is close to the gate of the mold, and then the pressure oil is introduced into the injection cylinder to push the screw forward, so that the molten material is injected into the closed mold with a lower temperature at a very high pressure and a faster speed. After a certain period of time and pressure maintenance and cooling, it is solidified and formed, and then the mold can be opened to take out the product. The basic requirements of injection molding are plasticization, injection and molding. Plasticization is the premise for achieving and ensuring the quality of molded products, and in order to meet the requirements of molding, the injection must ensure sufficient pressure and speed. At the same time, due to the high injection pressure, a high pressure is generated in the mold cavity accordingly, so there must be a sufficiently large clamping force. It can be seen that the injection device and the clamping device are key components of the injection molding machine.

[0004] However, in the prior art, when the injection device and the mold clamping device are docked, the operator basically relies on observing the docking status of the injection end of the injection device and the mold clamping device. Due to the complex actual working environment, the manual method is prone to misjudgment, which may require repeated docking and cannot improve work efficiency.

[0005] Therefore, it is urgent to provide an injection mold positioning device and a structural part to solve the above technical problems. Utility Model Content

[0027] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of 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.

[0028] Embodiment 1:

[0029] See also Figures 1 to 3 As shown, an embodiment of the utility model provides an injection mold positioning device, including a fixing member 1, a docking guide member 3 and a sensor 5, wherein the fixing member 1 is provided with a limiting groove 2; the docking guide member 3 is provided with a guide block 4 adapted to the limiting groove 2; the limiting groove 2 is configured to: limit the guide block 4, and when the guide block 4 moves from the limiting position to the guiding position, the guide block 4 is moved out; the sensor 5 is used to send an induction signal when the guide block 4 moves from the guiding position to the limiting position.

[0030] The width of the limiting groove 2 gradually increases from the limiting position to the guiding position. The width of the guide block 4 gradually increases from the limiting position to the guiding position and is adapted to the limiting groove 2.

[0031] Among them, the surface of the fixing member 1 on which the limiting groove 2 is provided is a plane, and the surface of the docking guide 3 on which the guide block 4 is provided corresponds to the surface of the fixing member 1 on which the limiting groove 2 is provided. That is, when the fixing member 1 needs to be docked with the docking guide 3, the guide block 4 is snapped into the limiting groove 2. When the guide block 4 just contacts the limiting groove 2, the guide block 4 is located at the limiting position of the limiting groove 2. At this time, the side with the smaller width of the guide block 4 is just connected to the side with the larger width of the limiting groove 2. Therefore, the docking guide 3 can be better docked with the fixing member 1.

[0032] Embodiment 2:

[0033] See also Figures 1 to 3As shown, an embodiment of the utility model provides an injection mold positioning device, including a fixing member 1, a docking guide member 3 and a sensor 5, wherein the fixing member 1 is provided with a limiting groove 2; the docking guide member 3 is provided with a guide block 4 adapted to the limiting groove 2; the limiting groove 2 is configured to: limit the guide block 4, and when the guide block 4 moves from the limiting position to the guiding position, the guide block 4 is moved out; the sensor 5 is used to send an induction signal when the guide block 4 moves from the guiding position to the limiting position.

[0034] A protective pad 6 is provided in the limiting groove 2. The protective pad 6 is made of nylon glass fiber composite material. Nylon glass fiber composite material has the characteristics of high temperature resistance, good dimensional stability, good toughness, good insulation, good corrosion resistance and wear resistance. When the limiting groove 2 of the fixing member 1 and the guide block 4 of the docking guide 3 are docked for many times, it is easy to cause wear of the fixing member 1 and the docking guide 3. Therefore, a nylon glass fiber composite material with high temperature resistance, good dimensional stability, good toughness, good insulation, good corrosion resistance and wear resistance is provided in the limiting groove 2, which can increase the service life of the fixing member 1 and the docking guide 3.

[0035] Embodiment three:

[0036] See also Figures 1 to 3 As shown, an embodiment of the utility model provides an injection mold positioning device, including a fixing member 1, a docking guide member 3 and a sensor 5, wherein the fixing member 1 is provided with a limiting groove 2; the docking guide member 3 is provided with a guide block 4 adapted to the limiting groove 2; the limiting groove 2 is configured to: limit the guide block 4, and when the guide block 4 moves from the limiting position to the guiding position, the guide block 4 is moved out; the sensor 5 is used to send an induction signal when the guide block 4 moves from the guiding position to the limiting position.

[0037] The sensor 5 includes a sensing end, and the sensing end is arranged at the limiting position of the limiting groove 2. The sensor 5 includes a signal light 7, and the signal light 7 is arranged on one side of the fixing member 1. After the fixing member 1 and the docking guide 3 are docked, it is necessary to confirm whether the docking is completed. In the prior art, the operator often confirms the docking status of the fixing member 1 and the docking guide 3 by observation. The sensing end of the sensor is arranged at the limiting position of the limiting groove 2, and the signal light 7 is arranged on the side of the fixing member 1. When the fixing member 1 and the docking guide 3 are docked, the docking status of the fixing member 1 and the docking guide 3 can be known by observing the information of the signal light 7, which greatly improves the efficiency of docking and thus increases the efficiency of production.

[0038] Embodiment 4:

[0039] On the one hand, a structural part is provided, which includes a clamping device, an injection device and an injection mold positioning device, including a fixing part 1, a docking guide 3 and a sensor 5, wherein the fixing part 1 is provided with a limit groove 2; the docking guide 3 is provided with a guide block 4 adapted to the limit groove 2; the limit groove 2 is configured to: limit the guide block 4, and when the guide block 4 moves from the limit position to the guide position, the guide block 4 moves out; the sensor 5 is used to send a sensing signal when the guide block 4 moves from the guide position to the limit position; the width of the limit groove 2 gradually increases from the limit position to the guide position; the width of the guide block 4 gradually increases from the limit position to the guide position, and is adapted to the limit groove 2; a protective pad 6 is provided in the limit groove 2; the protective pad 6 is a nylon glass fiber composite material; the sensor 5 includes a sensing end, and the sensing end is arranged at the limit position of the limit groove 2; the sensor 5 includes a signal light 7, and the signal light 7 is arranged on one side of the fixing part 1.

[0040] The fixing member 1 is installed on the mold clamping device, and the docking guide 3 is installed on the injection device; the fixing member 1 is connected to the mold clamping device through bolts; and the docking guide 3 is connected to the injection device through the bolts.

[0041] Among them, the fixing member 1 is installed on the mold clamping device through bolt connection, and the docking guide 3 is installed on the injection device through bolt connection. After the fixing member 1 is installed on the mold clamping device and the docking guide 3 is installed on the injection device, the injection device can be well docked with the mold clamping device through the positioning member formed by the fixing member 1 and the docking guide 3. Therefore, the operator confirms whether the injection device is docked with the mold clamping device by observing the machine in the prior art. In this application, a sensor 5 is set on the fixing member 1, that is, the sensing end of the sensor 5 is set at the limit position of the limit groove 2, and the signal light 7 of the sensor 5 is set on the side of the fixing member 1. When the injection device is docked with the mold clamping device, it is only necessary to observe the signal light 7 to confirm the docking status of the injection device and the mold clamping device. The operating difficulty of the operator is greatly reduced. The docking efficiency is improved, and then the efficiency of production and manufacturing is improved. It also avoids the problem of low work efficiency caused by manual methods in the existing technology.

[0042] In addition, in the actual injection molding production process, since the injection device only needs to reciprocate in the injection direction and will not rotate, a limit groove 2 is set on the fixing member 1, and a guide block 4 is set on the docking guide 3, and when the injection device and the clamping device are docked for the first time, the limit groove 2 and the guide block 4 are docked. In the subsequent use process, the positions of the guide block 4 and the limit groove 2 will not change easily. In this way, when the injection device and the clamping device are in operation, the process of adjusting the fixing member 1 and the docking guide 3 is omitted.

[0043] Moreover, a protective pad 6 is provided in the limit groove 2, and the protective pad 6 is a nylon glass fiber composite material. Since the nylon glass fiber composite material has the characteristics of high temperature resistance, good dimensional stability, good toughness, good insulation, good corrosion resistance and wear resistance. Since the injection mold needs to work in a high temperature and oily environment. Therefore, a protective pad 6 is provided in the limit groove 2, and the protective pad 6 is a nylon glass fiber composite material, which can better play the function of the protective pad 6, thereby effectively improving the service life of the injection device and the clamping device.

[0044] Furthermore, if the injection device and the mold clamping device cannot be docked, it is only necessary to adjust the bolts on the docking guide 3 and rotate the docking guide 3 so that the limit groove 2 of the fixing member 1 and the guide block 4 of the docking guide 3 can be matched again.

[0045] The beneficial effects of the utility model are:

[0046] The position is limited by the guide block on the docking guide and the limit groove on the fixing part, and the docking is automatically sensed by the sensor, which improves the docking efficiency and avoids the problem of low work efficiency caused by manual methods.
