In a nutshell, a mold is a tool used to make a shaped item, this tool is made up of various parts, and different molds are made up of different parts. It mainly realizes the processing of the shape of the article by changing the physical state of the formed material. Known as the "mother of industry", it is a tool for making blanks into parts with specific shapes and sizes under the action of external forces. It is widely used in blanking, die forging, cold heading, extrusion, powder metallurgy parts pressing, pressure casting, and compression molding or injection molding of engineering plastics, rubber, ceramics and other products. The mold has a specific contour or cavity shape, and the use of the contour shape with the cutting edge can separate the blank according to the contour shape (blanking). Applying the cavity shape allows the blank to obtain a corresponding three-dimensional shape. The mold generally includes two parts, a movable mold and a fixed mold (or a punch and a concave mold), which can be divided and combined. When separated, the parts are taken out, and when closed, the blanks are injected into the mold cavity to form. The mold is a precision tool with complex shape, which bears the expansion force of the blank, and has high requirements on structural strength, rigidity, surface hardness, surface roughness and machining accuracy.

The drive shaft is fixedly connected; the inner wall structure of the upper template is exactly the same as the inner structure of the lower template, and the placement groove of the upper template faces upwards in the initial state;

When working, most of the molds in the prior art are of non-automatic opening and closing design. At present, the mold with automatic opening and closing device is only suitable for one mold of the device. When individual molds need to be automatically opened and closed, a new one needs to be installed. The automatic mold opening and closing device limits the use range of the automatic opening and closing device, and at the same time increases the cost of work, thereby causing waste of resources. When the mold needs to be automatically opened and closed, the mold can be placed in the automatic mold opening and closing device, and then the mold can be fixed in the automatic mold opening and closing device through the work of the device, so as to inject different molds, thereby improving automatic opening and closing. The use of the mold clamping device also saves costs. When using the automatic mold opening and closing device made by the present invention, the fixing plate is first fixed on the production line with bolts, and the mold that needs to be injected is placed on the upper template and the lower template. Put it in the groove, and then control the expansion of the telescopic shaft fixed with the top plate through the controller. During the expansion of the telescopic shaft, the top plate can be driven to fit the mold, and the mold can be clamped and fixed in the process to prevent the mold from being injected. During the process, the mold is not firmly fixed and slips off, which affects the injection molding process of the mold. Since the top plate is spliced by evenly arranged top blocks, in the process of moving the top block to the mold, the top block can be based on the shape of the mold. Clamping, thereby preventing the top block from being fixed to the mold firmly. Since the outer surface of the top block is made of wear-resistant rubber material, it can prevent the top block or the mold from being damaged during the process of squeezing and fixing the top block to the mold. At the same time, the friction force of the top block to the mold can be increased, so that the fixing degree of the top block to the mold can be improved. When the outer surface of the mold has an irregular contour, the top block can be inserted into the irregular contour of the mold. Improve the fixation of the mold, so as to prevent the mold from falling off during the injection molding process. Since the inner wall of the top block is fixed with evenly arranged telescopic rods, when the outer contour of the mold is smaller than the width of the top block, the uniformly arranged The plunger can be further inserted into the outer contour of the mold. In this process, the degree of fixation of the mold can be further improved, thereby preventing the mold from falling during the injection molding process. When the mold is fixed, the controller controls the two motors. Rotation, the motor can drive the upper template to rotate during the process of rotation. When the upper template rotates 180 degrees, the motor stops rotating, and the controller controls the first electric telescopic rod to shrink downward. During the contraction of the first electric telescopic rod It can drive the mold in the upper template to move downward. When the mold in the upper template is fitted with the mold in the lower template, the injection molding of the mold starts at this time. After the injection of the mold is completed, the upper template returns to the initial state, and the The controller controls the top block to return to the initial state, and then the mold can be taken out.

Preferably, the opposite side surfaces of each of the top blocks are hinged with evenly arranged clamping shafts through struts, and the clamping shafts are placed between two adjacent layers of insertion rods; each of the clamping shafts is wear-resistant Made of rubber material; evenly arranged clamping balls are fixed on the outer surface of each clamping shaft, and the clamping balls are used to stabilize the mold;

During operation, since the outer surface of the top block is hinged with evenly arranged clamping shafts, when the mold slides in the placement groove, the evenly arranged clamping shafts can rotate with the mold, and stop when the clamping shaft rotates to a certain extent. During the process, the mold can be clamped to prevent the mold from shaking in the placement groove. Since the clamp shaft is made of wear-resistant rubber material, the friction force on the mold can be improved and the degree of fixation of the mold can be improved. There are evenly arranged clamping balls fixed on the surface. During the rotation of the clamping shaft, the clamping balls can be squeezed on the surface of the mold. In this process, the degree of fixation of the mold can be further improved, and at the same time, it can avoid the damage to the mold or the clamping shaft itself. damage.

When working, when using the automatic mold opening and closing device made by the present invention, the fixing plate 12 is first fixed on the production line with bolts, and the molds that need to be injected are placed in the placement grooves 13 of the upper template 11 and the lower template 1 at this time, Then, the top plate telescopic shaft that is fixed to the top plate is controlled by the controller to stretch, and the top plate can be driven to fit the mold during the stretching process of the telescopic shaft. Since the mold is not firmly fixed and slips off, since the top plate is formed by splicing the top blocks 14 evenly arranged, in the process of the top block 14 moving to the mold, the top block 14 can clamp the mold according to the shape of the mold. When the contour is irregular, the top block 14 can be inserted into the irregular contour of the mold, and in this process, the degree of fixation to the mold can be improved. When the outer contour is smaller than the width of the top block 14, the evenly arranged plungers 15 can be further inserted into the outer contour of the mold, and the degree of fixation to the mold can be further improved in this process, thereby preventing the mold from falling off during the injection molding process. After the mold is fixed, the controller controls the two motors 17 to rotate. During the rotation of the motors 17, the upper template 11 can be driven to rotate. When the upper template 11 rotates one hundred and eighty degrees, the motor 17 stops rotating and controls The controller controls the first electric telescopic rod 16 to shrink downward, and in the process of shrinking the first electric telescopic rod 16, it can drive the mold in the upper mold plate 11 to move downward. When the mold in the upper mold plate 11 and the mold in the lower mold plate 1 occur After fitting, the injection molding of the mold starts at this time. When the injection molding of the mold is completed, the upper template 11 returns to the initial state, and the controller controls the top block 14 to return to the initial state, and then the mold can be taken out. When the height is lower than the height of the placement slot 13, the mold is placed in the placement slot 13 at this time, and then the evenly arranged pressing rods 291 are pressed down. During the downward movement of the pressing rods 291, the gear plate 29 can be driven to move downward. , Since the gear plate 29 and the gear plate 28 are meshed with each other, the gear plate 28 can be driven to rotate during the movement of the gear plate 29, and the lead screw 27 can be driven to rotate during the rotation of the gear plate 28. Since the lead screw 27 and the support tube 26 The inner threads are engaged with each other, and during the rotation of the lead screw 27, the support tube 26 can be pushed to move to the center position. Since the support tube 26 is fixedly connected with the support block 23, the support block 23 can be driven to move to the bottom of the long board 21. When the block 23 moves to the bottom of the long board 21, the long board 21 can be supported. Since the long blocks 22 are evenly arranged on the upper surface of the long board 21, the long blocks 22 can be driven to move into the placing slot 13. During this process can push the mold to move up.
