Description

Technical Field

[0001] The present invention relates to the technical field of flowmeter processing, and particularly to an integrated molding device for flowmeter processing. Background Technique

[0002] A flowmeter is an instrument that indicates the measured flow rate and / or the total amount of fluid within a selected time interval. Flowmeters are classified into differential pressure flowmeters, rotameters, throttling flowmeters, slit flowmeters, volumetric flowmeters, electromagnetic flowmeters, ultrasonic flowmeters, etc. according to their measurement principles.

[0003] Among them, an electromagnetic flowmeter applies the principle of electromagnetic induction to measure the flow rate of a conductive fluid based on the electromotive force generated when the conductive fluid passes through an externally applied magnetic field. The structure of an electromagnetic flowmeter is usually a measuring tube equipped with induction electrodes. The measuring tube and the induction electrodes usually need to be produced separately and then assembled. This production method not only has low efficiency, but also during long-term use, due to the wear of the measuring tube and the probe, as well as factors such as thermal expansion and contraction between the two, the gap between the measuring tube and the probe will expand, resulting in leakage, electrode short-circuit, and the shell getting wet, causing the detection accuracy of the flowmeter to decline.

[0051] The mold mechanism 300 is used for processing and forming the flowmeter 200. The flowmeter 200 includes a measuring tube 210.

[0063] A first turning mechanism 700 is arranged on the right side of the first double-axis displacement assembly 600. The first turning mechanism 700 is used to turn over the two mold cores 310 and the fixed mold 320;

[0064] A third slideway 140 that is communicated with the second slideway 130 is also opened on the slide rail 110. Drive the two mold cores 310 and the fixed mold 320 to slide from left to right along the third slideway 140 through the conveying mechanism 400;

[0065] On the right side of the first turning mechanism 700, there is a primary molding mechanism 800. The primary molding mechanism 800 includes a third cylinder 810 and a first feeder 820 arranged on the workbench 100. The piston rod of the third cylinder 810 is connected to the first moving mold 330, and the first feeder 820 is connected to the first moving mold 330 through a first connecting pipe 830;

[0066] The first moving mold 330 is driven by the third cylinder 810 to press against the fixed mold 320, and the first feeder 820 and the first connecting pipe 830 are used to inject materials into the mold mechanism 300, so as to mold the measuring tube 210;

[0067] The first turning mechanism 700 includes a sliding seat 710 and a second cylinder 720 arranged on the workbench 100. The piston rod of the second cylinder 720 is connected to the sliding seat 710, and two first clamping assemblies 730 are symmetrically arranged on the sliding seat 710;

[0068] The first clamping assembly 730 includes a first mounting seat 731 rotatably arranged on the sliding seat 710. Two first clamps 732 are slidably arranged on the first mounting seat 731. A first hollow rod 733 is also arranged on the first mounting seat 731. A first guide rod 734 is slidably arranged on the first hollow rod 733. A first guide groove 735 is formed on the workbench 100, and the first guide rod 734 is slidably connected in the first guide groove 735;

[0069] The first clamping assembly 730 further includes two first connecting rods 736. One ends of the two first connecting rods 736 are respectively movably hinged to the first guide rod 734 through hinge shafts, and the other ends of the two first connecting rods 736 are respectively movably hinged to the two first clamps 732 through hinge shafts;

[0070] Gears 740 are arranged on both first hollow rods 733, and two racks 750 are symmetrically arranged on the workbench 100. The two gears 740 are respectively meshed with the two racks 750.

[0071] In this embodiment: First, along the slope on the left side of the slide rail 110, several groups of mold cores 310 can be conveyed equidistantly to the right. Each group of mold cores 310 consists of two symmetric mold cores 310 in the front and back. Considering the special shape of the flowmeter 200, two mold cores 310 with tapers are selected to form the internal structure of the mold.

[0072] The two core molds 310 slide down along the first slideway 120 and fall between the second fixtures 422 of the first group to be clamped and conveyed to the right. When they reach the position of the two first air cylinders 500, they stop. The two first air cylinders 500 push the two core molds 310 to slide towards each other along the connecting part of the first slideway 120 and the second slideway 130 and fit together. Then the belt conveying device 410 continues to convey the two core molds 310 to slide to the right along the second slideway 130 and stop at the first double-axis displacement assembly 600.

[0073] Another set of belt conveying devices 410 can be arranged at the rear side of the workbench 100 for equidistantly conveying a plurality of fixed molds 320. The first screw conveying device 610 and the second screw conveying device 630 control the displacement of the first vacuum suction cup 650 in the front-back and up-down directions, and adsorb a fixed mold 320 and place it on the two core molds 310. The first screw conveying device 610 and the second screw conveying device 630 can be composed of a motor, a screw, a nut, etc. The first vacuum suction cup 650 can be connected to a vacuum pump, and the vacuum pump operates to generate suction for grasping objects. The above belong to conventional technical means and will not be elaborated.

[0074] The middle part of the fixed mold 320 has a frustum-shaped protrusion, which abuts against the two core molds 310 and can form a shape consistent with the induction electrode 230. When the belt conveying device 410 continues to drive the two core molds 310 and the fixed mold 320 to move to the right along the third slideway 140 to the first turning mechanism 700, the second air cylinder 720 drives the slide seat 710 to move synchronously with the belt conveying device 410. During this process, the two first fixtures 732 shown in the initial state as Figure 10 will first rotate clockwise and approach to clamp the two core molds 310 and the fixed mold 320, and then rotate 180° while maintaining the clamping state. The two first fixtures 732 then move away from each other to release the two core molds 310 and the fixed mold 320, thereby turning the fixed mold 320 to the lower side.

[0075] Specifically, taking a set of first clamping components 730 located at the rear side in Figure 4 and Figure 5 as an example, the first guide rod 734 slides to the right along the trapezoidal first guide groove 735. First, under the guidance of the first guide groove 735, the first guide rod 734 moves backward, and through the transmission of the two first connecting rods 736, the two first fixtures 732 approach each other. Then the first guide rod 734 moves along the horizontal part of the first guide groove 735, and then under the guidance of the first guide groove 735, the first guide rod 734 moves forward, causing the two first fixtures 732 to move away from each other. At the same time, during this process, the gear 740 rolls along the rack 750, causing the first guide rod 734, the first hollow rod 733, and the first mounting seat 731 to rotate.

[0076] After turning over, the belt conveying device 410 continues to convey, causing the two mold cores 310 and the fixed mold 320 to stop at the primary molding mechanism 800. The third cylinder 810 drives the first moving mold 330 to move downward and fit onto the fixed mold 320. The first moving mold 330 has the same structure as the fixed mold 320 and also has a frustum-shaped protrusion. Then, the first injection machine 820 injects raw materials in different forms into the gap between the fixed mold 320, the first moving mold 330, and the two mold cores 310 according to the material of the measuring tube 210, forming the measuring tube 210 with two reserved holes 220. The primary molding mechanism 800 can select different models of equipment according to the conveyed material. As a conventional technical means, it will not be elaborated.

[0077] In addition, during the conveying process, before reaching the first turning mechanism 700, as Figure 6 shown, the corresponding part of the second guide groove 425 in front of the first slideway 120 to the first turning mechanism 700 is at a lower position, and the corresponding part after passing through the inclined section and in front of the first turning mechanism 700 is at a higher position. Through the guiding action of the second guide groove 425, the two second clamps 422 are closer together in front of the first turning mechanism 700 to hold the two mold cores 310, and after the fixed mold 320 is assembled and turned over, the distance between the two second clamps 422 is lengthened to hold the fixed mold 320.

[0079] The second injection machine 920 injects material into one of the reserved holes 220, and then the first second moving mold 340 is pressed against the fixed mold 320 through the second double-axis displacement assembly 940, thereby integrally forming the first induction electrode 230 on the measuring tube 210;

[0080] On the right side of the secondary molding mechanism 900, there is a second turning mechanism 1000. The second turning mechanism 1000 has the same structure as the first turning mechanism 700. The second turning mechanism 1000 is used to turn over the two mold cores 310, the fixed mold 320, and the second moving mold 340;

Through the three - time molding mechanism 1100, material is injected into another reserved hole 220, and then the second second moving die 340 is pressed against the first second moving die 340 by the three - time molding mechanism 1100, so that the second induction electrode 230 is integrally formed on the measuring tube 210;

[0082] On the right side of the three - time molding mechanism 1100, there is a blanking mechanism 1200. The blanking mechanism 1200 includes a third double - axis displacement assembly 1210 arranged on the workbench 100 and two fifth cylinders 1220.

A second vacuum chuck 1230 is arranged on the piston rod of the fifth cylinder 1220;

[0083] After driving the two second vacuum chucks 1230 to take out the two mold cores 310 by the two fifth cylinders 1220, the flowmeter 200 is taken out by the third double - axis displacement assembly 1210.

[0084] In this embodiment: After the measuring tube 210 is formed, the third cylinder 810 drives the first moving die 330 to lift, and then the belt conveyor 410 continues to convey the two mold cores 310, the fixed die 320 and the measuring tube 210 to move rightward and pauses when reaching the two - time molding mechanism 900. The fourth cylinder 910 drives the second connecting pipe 930 to align with a reserved hole 220 for injecting material, and then a second moving die 340 is grabbed from another conveying device by the second double - axis displacement assembly 940 and covered on the fixed die 320. The second moving die 340 has the same structure as the fixed die 320 but without a round - table protrusion. An induction electrode 230 can be formed by the molding of the second moving die 340.

[0085] Then, the fixed die 320 and the second moving die 340 are turned over by the second turning mechanism 1000. The fixed die 320 is taken by the three - time molding mechanism 1100, material is injected into another reserved hole 220, and then another second moving die 340 is grabbed and covered on the previous second moving die 340, and another induction electrode 230 is molded by pressing.

[0086] Finally, the other second moving die 340 is removed, the two mold cores 310 are extracted by the two fifth cylinders 1220 and the second vacuum chucks 1230, and then the flowmeter 200 is removed by the third double - axis displacement assembly 1210.
