Description

Technical Field

[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 known as the "mother of industry". It is a tool that makes the blank into a part with a specific shape and size under the action of external force. It is widely used in punching, die forging, cold heading, extrusion, powder metallurgy pressing, pressure casting, and compression or injection molding of engineering plastics, rubber, ceramics and other products. The mold has a specific contour or inner cavity shape. The use of a contour shape with a cutting edge can make the blank separate (punch) according to the contour shape. The use of an inner cavity shape can make the blank obtain a corresponding three-dimensional shape. The mold generally consists of two parts: a movable mold and a fixed mold (or a punch and a die), which can be separated or combined. When separated, the part is taken out, and when closed, the blank is injected into the mold cavity for forming. The mold is a precision tool with a complex shape. It bears the expansion force of the blank and has high requirements for structural strength, rigidity, surface hardness, surface roughness and processing accuracy. The development level of mold production is one of the important indicators of the level of mechanical manufacturing. In the prior art, there are mold blanks produced continuously. Multiple identical mold blanks are connected together and need to be manually divided. However, since the mold blanks produced continuously are of different lengths, they cannot be clamped individually. Therefore, the spacing between the rotating tools needs to be adjusted at any time during continuous cutting, and mold cutting is a necessary process in mold production.

[0025] The slide rail 302 is provided with a slide groove, and the ball slider 304 slides in cooperation with the slide groove on the slide rail 302 .

[0026] The processing table assembly 1 includes a chassis 101, a back plate 102 and a side plate 103. Two side plates 103 are provided. The two side plates 103 are respectively installed at the left and right ends of the chassis 101 and are slidably connected to the chassis 101. Two driving assemblies 104 are fixedly installed at the bottom of the chassis 101, which are respectively used to drive the two side plates 103 to move relative to the chassis 101. Two cross slide assemblies 2 are respectively fixed on the two side plates 103. The back plate 102 is fixed to the rear end of the chassis 101. Two hydraulic cylinders 105 are fixedly installed on the back plate 102. The output ends of the hydraulic cylinders 105 are fixedly installed with rear top plates 106. A plurality of front top plates 107 are fixedly installed at the front end of the upper surface of the chassis 101. The hydraulic cylinder 105 is square, and its output shaft cross-section is rectangular, which can be connected to the longer rear top plate 106. Each hydraulic cylinder 105 contains multiple small oil cylinders inside, which jointly apply pressure to the rectangular output shaft of the hydraulic cylinder 105. There are multiple front top plates 107 arranged in parallel, and the spacing between them is the same. The front top plate 107 is installed on the chassis 101 with bolts and can be removed or repositioned. The side plate 103 is slidably connected to the chassis 101 and fits seamlessly.

[0027] A plurality of oil outlet holes 108 are provided on the upper surface of the chassis 101, and the oil outlet holes 108 are distributed in a matrix. An oil storage box 109 is fixedly installed on the bottom surface of the chassis 101, and any oil outlet hole 108 is connected to the inside of the oil storage box 109. An oil pump for pumping oil out of the oil holes 108 is installed in the oil storage box 109.

[0029] The oil outlet hole 108 is a micropore, and the interior of the oil storage box 109 is filled with lubricating oil or engine oil mixture, which can achieve lubrication, cold cutting and other effects. The oil pump in the oil storage box 109 can increase the pressure of the oil inside the oil storage box 109, and then the oil will slowly seep out from the oil outlet hole 108.

The oil leakage groove 110 is a rectangular circle. When the mold slides, the oil at the bottom will be scraped off by the oil leakage groove 110 to prevent too much oil from sticking to the bottom of the mold, resulting in waste of lubricating oil.

[0030] The cross slide assembly 2 includes a support column 201, a connecting frame 202 and a servo motor B203. The support column 201 is fixed to the rear end of the upper surface of the side plate 103, the connecting frame 202 is fixed to the upper end of the support column 201, and the support column 201 is connected to the rear end of the bottom surface of the connecting frame 202. The connecting frame 202 extends forward as a whole. The servo motor B203 is fixed to the upper end of the connecting frame 202, and its output shaft is fixedly installed with a lead screw A204, which is installed in the connecting frame 202 and supported by it for rotation. The connecting rod 301 is in the connecting frame 202, and the front and rear ends of the connecting rod 301 are fixedly installed with a sliding sleeve 205, which is installed on the connecting rod 301 and slidably connected to it. The lead screw A204 is used to drive the connecting rod 301 to move up and down along the connecting frame 202.

[0031] The support column 201 is thicker in diameter than the connection frame 202 and is thinner at the top and thicker at the bottom. It is installed on one side of the connection frame 202 to support the entire connection frame 202.

[0033] The visible light emitting group 112 is a laser emitter, which has multiple laser emitting lamps arranged in parallel inside. Any laser emitting lamp only occupies a small width, which can realize simple laser communication. The laser range of the visible light emitting group 112 is long, and the corresponding laser emitting lamp can be found at the mold joints on the chassis 101.

[0034] The cutting assembly 305 includes a servo motor C3051, a speed change frame 3052 and a cutting blade 3053. The servo motor C3051 is fixed to the bottom surface of the ball slider 304 and is fixedly connected to the speed change frame 3052.

The rotational force of the servo motor C3051 is transmitted to the cutting blade 3053 through the speed change frame 3052. A visible light receiving sensor 3054 is installed on each servo motor C3051.

[0035] The visible light receiving sensor 3054 is used in conjunction with the visible light emitting group 112 , and both are modified from existing laser emitting receivers.

[0036] A plurality of visual sensors 113 are mounted on the back panel 102 above the visible light emission group 112 .

[0037] The visual sensor 113 is composed of multiple cameras, which needs to cooperate with the CPU. Before cutting the mold, the staff gradually uploads photos for the visual sensor 113 to judge. After learning and judging, the subsequent continuous molds can be recognized by the visual sensor 113 and find the joints between two identical molds. After finding the position of the joint, the signal is transmitted to the CPU. After processing by the CPU, the laser emitter emits laser at the corresponding position, and then the visible light receiving sensor 3054 can accurately find the position of the laser emission, and then the cutting component 305 can respond to the laser, thereby realizing a precise operation on the connection of the mold.

[0038] The ball screw assembly 303 includes a servo motor D3031 and a screw B3032. The screw B3032 is arranged on the slide rail 302 and is rotatably connected thereto.

The gear 1042 is fixedly mounted on the output shaft of the servo motor A1041, and the gear 1042 is meshed with the rack 1043.

[0041] The gear 1042 is relatively small, and the servo motor A1041 is controlled by the CPU to accurately cooperate with the rack 1043 to move the side plate 103 .

[0042] When in use, when the blank mold is transferred to the chassis 101 by the conveyor belt, the oil outlet 108 of the chassis 101 will pump oil to soak the upper surface of the chassis 101, so that there is an oil film between the metal mold and the chassis 101, so that the mold can slide on the chassis 101 with less resistance, without setting up equipment such as conveyor belts or rollers, and two groups of hydraulic cylinders 105 cooperate with the rear top plate 106 and the front top plate 107 to clamp the mold on the side, and release it after processing. The continuous mold can continue to move forward from the rear, and the parallel knife assembly 3 and the cross slide assembly 2 do not affect the continuous movement of the mold. The ball screw assembly 303 can adjust the position of multiple cutting assemblies 305 on the slide rail 302 at any time during operation, so as to adjust the cutting The spacing between the cutting blades 3053, the cross slide assembly 2 can also move the cutting assembly 305 down close to the mold, and the driving assembly 104 is used to drive the two side plates 103, so as to control the cutting assembly 305 to cut the mold forward and backward. When the continuously produced blank mold is transferred to the chassis 101, the connection position of the mold can be judged according to the visual sensor 113, and then the visible light emitting group 112 emits visible light at the connection. The visible light receiving sensor 3054 included in the cutting assembly 305 obtains the position of the connection at this time, and then the ball screw assembly 303 can transfer the cutting assembly 305 to the mold connection at this time to cut it off. When cutting the mold, the side plate 103 can be fed intermittently to ensure smooth and accurate cutting.
