Description

Technical Field

[0001] The utility model relates to the technical field of mold production, in particular to a precise positioning displacement device for mold production. Background Art

[0002] 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 widely used in blanking, die forging, cold heading, extrusion, powder metallurgy pressing, pressure casting, and compression or injection molding of engineering plastics, rubber, ceramics and other products. The existing molds are generally provided with an upper mold and a lower mold that match each other, that is, the mold is composed of an upper mold and a lower mold. When the upper mold and the lower mold are closed, it is easy to be misaligned. It is necessary to provide a positioning device on the upper mold and the lower mold to ensure accurate positioning when the upper and lower molds are closed.

[0003] Existing mold production shifting devices usually have a positioning rod to assist in mold closing. However, due to factors such as vibration caused by long-term operation of the equipment, the position between the upper and lower mold boxes may be offset. In this case, when the mold is closed, the position of the cylinder cannot be automatically adjusted, causing the positioning rod to conflict with the upper surface of the positioning sleeve. In severe cases, the positioning rod will break, resulting in the inability to correctly control the mold closing accuracy.

[0004] Therefore, the above-mentioned mold production shifting device lacks a positioning component, which makes the cylinder unable to automatically adjust and easily causes the problem of mutual interference between the positioning rod and the positioning sleeve, which urgently needs to be solved to improve the use scenario of the mold production shifting device. Utility Model Content

[0005] In order to overcome the common shifting device used in mold production, the vibration caused by the long-term operation of the equipment and other factors will cause the position between the upper and lower mold boxes to shift. In this case, when the mold is closed, the position of the cylinder cannot be adjusted automatically, which will cause the positioning rod to conflict with the upper surface of the positioning sleeve. In severe cases, the positioning rod will break, resulting in the problem that the mold closing accuracy cannot be correctly controlled.

[0006] The technical solution of the utility model is: a precisely positioned shifting device for mold production, comprising a workbench, mutually symmetrical support rods are installed at the corners of the upper surface of the workbench, the top surface of the support rods is connected with a top cover, a positioning assembly is arranged on the lower surface of the top cover, a telescopic cylinder is arranged below the positioning assembly, an upper mold box is installed on the bottom surface of the telescopic cylinder, a lower mold box is arranged at the center of the upper surface of the workbench, mutually symmetrical limiting assemblies are arranged on the left and right sides of the upper mold box and the upper surface of the workbench, and a distance measuring assembly is arranged at the front end of the upper surface of the workbench.

[0007] Preferably, the docking process of the upper mold box and the lower mold box can be limited by the limiting component. At the same time, during the limiting process, if there is a deviation, the position of the telescopic cylinder will be adjusted by the positioning component to increase the positioning accuracy, and the downward pressure distance of the telescopic cylinder can be controlled by the distance measuring component, thereby controlling the pressure between the upper mold box and the lower mold box, thereby solving the problem that the cylinder position of the existing device is not easy to adjust and the positioning device of the equipment is prone to damage.

[0008] Preferably, the limit assembly includes a connecting rod, a limit rod and a limit cylinder; symmetrical connecting rods are installed on the left and right sides of the upper surface of the upper mold box, the limit rods are installed on the bottom surface of the connecting rods, and symmetrical limit cylinders are installed on the left and right sides of the upper surface of the workbench, the limit cylinders are matched with the limit rods, and the bottom of the limit rod and the top of the limit cylinder are chamfered. By adopting a chamfered design for the contact surface between the limit rod and the limit cylinder, direct contact between the two planes can be avoided when there is a position deviation, reducing the risk of the limit rod breaking, and instead, through the contact of the arc surface, the limit rod can slide into the interior of the limit cylinder, which is smoother and more stable.

[0009] Preferably, the positioning assembly includes a slide groove, a slider, a slide rod and a movable seat; the inner surfaces of the four sides of the top cover are provided with mutually symmetrical slide grooves, the inside of the slide grooves are slidably connected with sliders, and slide rods are connected between the symmetrical sliders. The two slide rods are staggered, and the middle surfaces of the two slide rods are slidably connected with the movable seat. By setting the slider, when deviation occurs, the limit rod will cause the slider to slide inside the slide groove during the process of inserting the limit rod into the limit cylinder, so that the slide rod drives the movable seat to move, thereby adjusting the position of the cylinder and the upper mold box so that it can be accurately docked with the lower mold box.

[0010] Preferably, the positioning assembly includes an electric push rod, a positioning rod and a positioning hole. The inner bottom surface of the moving seat is equipped with symmetrical electric push rods. The telescopic end of the electric push rod is equipped with a positioning rod. The upper end of the positioning rod can pass through the moving seat. The bottom surface of the top cover is provided with a positioning hole, and the positioning hole matches the positioning rod. Through the operation of the electric push rod, the positioning rod will be driven to extend upward and inserted into the interior of the positioning hole, thereby fixing the position of the moving seat to avoid displacement of the moving seat during operation.

[0011] Preferably, the distance measuring assembly includes a ruler and a damping ring; a ruler is installed on the front side of the upper surface of the workbench, and a damping ring is provided on the outer surface of the ruler. By moving the damping ring up and down to different scale lines on the surface of the ruler, the staff can intuitively observe and control the downward distance of the telescopic cylinder.

[0012] Preferably, the ranging assembly includes a pressure sensor and a probe. The pressure sensor is installed at the end of the upper surface of the damping ring, and the probe is installed on the front surface of the upper mold box. When the telescopic cylinder drives the upper mold box downward, the probe will contact the pressure sensor. When in contact, the pressure sensor will transmit a signal to the control module of the telescopic cylinder to stop working, thereby ensuring the depth of the die and the quality of the die.

[0013] Preferably, a controller is installed in the groove on the front surface of the lower mold box, and a switch is provided on the top surface of the controller. When the switch is pressed, the upper surface is flush with the upper surface of the lower mold box. By setting the switch, during the downward pressing of the upper mold box, its bottom surface will contact the upper surface of the switch and press the switch. Then the controller transmits instructions to the electric push rod, prompting it to push the positioning rod out to complete automatic limit fixation.

[0014] Beneficial effects of the utility model:

[0015] 1. The docking process of the upper mold box and the lower mold box can be limited by setting the limit component. At the same time, during the limiting process, if there is a deviation, the position of the telescopic cylinder will be adjusted by the adjustment component to increase the positioning accuracy, and the downward pressure distance of the telescopic cylinder can be controlled by the distance measuring component, so as to control the pressure between the upper mold box and the lower mold box, so as to solve the problem that the cylinder position of the existing device is not easy to adjust and the positioning device of the equipment is easy to be damaged;

[0016] 2. By setting a slider, when deviation occurs, the limit rod will cause the slider to slide inside the slide groove during the process of inserting the limit cylinder, so that the slide rod drives the moving seat to move, thereby adjusting the position of the cylinder and the upper mold box so that it can be accurately docked with the lower mold box, and through the operation of the electric push rod, it will drive the positioning rod to extend upward and insert into the positioning hole, thereby fixing the position of the moving seat to avoid displacement of the moving seat during operation.

[0028] During operation, by adopting a chamfered design for the contact surface between the limit rod 82 and the limit cylinder 83, when there is a position deviation, direct contact between the two planes can be avoided, reducing the risk of the limit rod 82 breaking, and instead, through the contact of the arc surface, the limit rod 82 can slide into the interior of the limit cylinder 83, which is smoother and more stable, and by providing a slider 42, when there is a deviation, the limit rod 82 will cause the slider 42 to slide inside the slide groove 41 during the process of inserting the limit cylinder 83, so that the slider 43 drives the moving seat 44 to move, thereby adjusting the position of the cylinder and the upper mold box 6 so that it can be accurately docked with the lower mold box 7, and through the operation of the electric push rod 45, the positioning rod 46 will be driven to extend upward and insert into the interior of the positioning hole 47, thereby adjusting the moving seat 44 to adjust the position of the cylinder and the upper mold box 6.
