Description

Technical Field

[0001] This utility model relates to the field of mold clamping technology, specifically to a mold clamping position detection device. Background Art

[0002] Molds are widely used in industry. In actual use, molds need to be clamped and fixed by external clamping devices to ensure that the product inside the mold is dimensionally accurate. A mold clamp is a fixture used to fix the mold.

[0003] Chinese Patent Publication No. CN113770260A, published on December 10, 2021, discloses a mold clamping device for position detection, comprising a housing with mounting plates on the front and rear sides of the top surface of the housing. This invention records the number of rotations of the rollers using two sets of Hall effect sensors. Based on the number of roller rotations and the displacement distance calculated by the computer, data from proximity sensors is used as a reference. Data from a first pressure sensor and a second pressure sensor are also used for reference. When both sets of data are within a threshold range, the mold clamping device is considered operational. This increases the amount of position and pressure detection data for the mold clamping device, forming a data chain that mutually corroborates each other, preventing errors in a single set of data from causing subsequent device malfunctions and production problems.

[0004] The existing technical solutions mentioned above have the following drawbacks: when the mold size and shape are not standard, or when foreign objects appear during the movement of the mold clamping device, the position of the mold cannot be accurately determined by the proximity sensor, making it impossible for the mold clamping device to hold the mold securely. Therefore, we propose a mold clamping device position detection device to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide a mold clamping device for position detection, in order to solve the problem that the commonly used mold clamping devices mentioned in the background art cannot accurately determine the position of the mold through proximity sensors when the mold size and shape are not standard or when foreign objects appear during the movement of the mold clamping device, thus making it impossible for the mold clamping device to hold the mold securely.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a clamping device for detecting the position of a mold clamp, comprising:

[0007] The insert plate has a mold clamping housing on its top, and a shaft is rotatably mounted on the top right side of the mold clamping housing.

[0008] A hydraulic cylinder, which is embedded in the top left side of the mold clamp housing;

[0009] A pressure plate, which is fixedly connected to the outside of the shaft;

[0010] A connecting frame is slidably installed inside the mold clamp housing, and a push plate is fixedly connected to the right end of the connecting frame.

[0011] A rangefinder is installed inside the left side of the mold clamp housing.

[0012] Preferably, a handle is fixedly connected to the left side of the mold clamp housing, and an oil inlet pipe is installed on the bottom left side of the mold clamp housing.

[0013] Preferably, the oil inlet pipe is connected to the oil cylinder.

[0014] Preferably, a front pressure head is fixedly connected to the right side of the pressure plate, and a rear pressure head is fixedly connected to the left side of the pressure plate.

[0015] Preferably, the rear pressure head is located at the top of the hydraulic cylinder.

[0016] Preferably, the front and rear sides of the connecting frame are slidably installed inside the mold clamp housing, and a spring is connected to the outer side of the connecting frame to reset it to the right.

[0017] Preferably, a distance measuring plate is provided on the inner side of the connecting frame, and the distance measuring plate is located directly in front of the working end of the distance measuring instrument.

[0018] Preferably, the pusher plate has a rectangular structure.

[0019] Preferably, a receiving groove is provided on the right side of the mold clamp housing.

[0020] Preferably, the push plate and the receiving groove are adapted to each other.

[0021] Compared with the prior art, the beneficial effects of this utility model are: when the mold size and shape are not standard, or when foreign objects appear during the movement of the mold clamp, the position detection device can accurately judge the position of the mold by monitoring the position of the push plate, so that the mold clamp can firmly hold the mold.

[0022] The insert plate is slidably mounted on the machine tool. When the insert plate moves, it drives the mold clamping housing closer to the mold. When the push plate contacts the mold, it is squeezed and moves towards the inside of the mold clamping housing. At this time, the rangefinder monitors the change in the position of the rangefinder plate. When the mold squeezes the push plate to move into the inside of the receiving groove, the rangefinder reaches the set monitoring distance. The rangefinder feeds the data back to the controller. At this time, the oil cylinder of the oil inlet pipe lifts the rear pressure head, so that the front pressure head clamps and fixes the mold. When the mold is released from fixation, the connecting frame is reset to the right by the spring. Attached Figure Description

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Please see Figure 1-6This utility model provides a technical solution: a clamping device for detecting the position of a clamping device, comprising: a plate 1, a clamping device housing 2 on the top of the plate 1, a shaft 6 rotatably mounted on the top right side of the clamping device housing 2; an oil cylinder 5, embedded in the top left side of the clamping device housing 2; a pressure plate 7, fixedly connected to the outside of the shaft 6; a connecting frame 10, slidably mounted inside the clamping device housing 2, a push plate 11 fixedly connected to the right end of the connecting frame 10; and a rangefinder 14, mounted inside the left side of the clamping device housing 2. A handle 3 is fixedly connected to the left side of the clamping device housing 2, and an oil inlet pipe 4 is installed on the bottom left side of the clamping device housing 2. The oil inlet pipe 4 is connected to the oil cylinder 5. A front pressure head 8 is fixedly connected to the right side of the pressure plate 7, and a rear pressure head 9 is fixedly connected to the left side of the pressure plate 7. The rear pressure head 9 is located on top of the oil cylinder 5. The connecting frame 10 is slidably mounted inside the mold clamp housing 2 on both its front and rear sides. A spring 12 is connected to the outer side of the connecting frame 10 to return it to its rightward position. A distance measuring plate 13 is provided on the inner side of the connecting frame 10, located directly in front of the working end of the distance measuring instrument 14. The push plate 11 has a rectangular structure. A receiving groove 15 is provided on the right side of the mold clamp housing 2. The push plate 11 and the receiving groove 15 are mutually compatible.

[0032] When using the clamping device for position detection, such as Figures 1-6 The insert plate 1 is slidably mounted on the machine tool. When the insert plate 1 moves, it drives the clamping device housing 2 closer to the mold. When the push plate 11 contacts the mold, it is squeezed and moves towards the inside of the clamping device housing 2. At this time, the rangefinder 14 monitors the change in the position of the rangefinder plate 13. When the mold squeezes the push plate 11 and moves into the inside of the receiving groove 15, the rangefinder 14 reaches the set monitoring distance. The rangefinder 14 feeds the data back to the controller. At this time, the oil inlet pipe 4 and the oil cylinder 5 lift the rear pressure head 9, so that the front pressure head 8 clamps and fixes the mold. When the mold is released from fixation, the spring 12 resets the connecting frame 10 to the right. When the mold is irregular in size or shape, or when foreign objects appear during the movement of the clamping device, the device can accurately judge the position of the mold by monitoring the position of the push plate, so that the clamping device can firmly clamp the mold. This is the whole working process of the clamping device position detection device.
