[0030] like Figure 4-6 As shown, this example can achieve the effect of convenient demoulding of the ring-shaped plastic.
[0031] Since the plastic molding equipment includes a circular plate 101, a convex column 103 is welded to the center of the upper side of the circular plate 101, two convex rods 102 are welded to the edge of the circular plate 101, a bottom rod 209 is welded to the lower end of the inner cylinder 208, and the bottom rod 209 is inserted into the convex column 103, and a convex seat 204 is fixed to the edge of the outer cylinder 201, and the two convex seats 204 are respectively inserted into the two convex rods 102, the bottom rod 209 and the inner cylinder 208 are positioned by the convex column 103, and the outer cylinder 201 is positioned by inserting the two convex rods 102, so that the outer cylinder 201 and the inner cylinder 208 are fixed on the circular plate 101, thereby forming an annular space, and the molten plastic is poured into the annular space to form an annular plastic, and then the outer cylinder 201 and the inner cylinder 208 are conveniently removed from the circular plate 101, thereby facilitating demoulding of the annular plastic.
[0032] like Figure 5-6 As shown, this example can achieve the effect of improving the strength of the formed annular plastic by using the two annular iron wires 301 .
[0033] Since the outer cylinder 201 is provided with four transverse columns 202 in an annular sliding connection, and the outer cylinder 201 is provided with four transverse columns 202 in an annular sliding connection, a slot 205 is provided at the end of each transverse column 202, and the transverse column 202 can slide on the outer cylinder 201 or the inner cylinder 208, and then the annular iron wire 301 can be supported by the slots 205 on the four transverse columns 202 on the outer cylinder 201 or the inner cylinder 208, and then the annular iron wire 301 is suspended in the annular space, an annular iron wire 301 is provided at the end of the four transverse columns 202 on the outer cylinder 201, and an annular iron wire 301 is also provided at the end of the four transverse columns 202 on the inner cylinder 208, and then the molten plastic is poured into the annular space to bury the annular iron wire 301 in the plastic, and the strength of the formed annular plastic can be improved by the two annular iron wires 301.
[0034] like Figure 5-6 As shown, this example can achieve the effect that the crossbar 202 cannot slide further after sliding into position.
[0035] Since a stop pin 203 is welded on the cross column 202, the stop pin 203 on the cross column 202 on the outer cylinder 201 is located on the outside of the outer cylinder 201, and the stop pin 203 on the cross column 202 on the inner cylinder 208 is located on the inside of the inner cylinder 208. The stop pin 203 is used to limit the sliding of the cross column 202, so that the cross column 202 cannot continue to slide after sliding into place.
[0036] like Figure 5-8 As shown, this example can achieve the effect of further improving the strength of the annular plastic by using four straight iron wires 302 .
[0037] Since four vertical grooves 1 206 are arranged in a ring shape on the outer cylinder 201, and four vertical grooves 207 are arranged in a ring shape on the inner cylinder 208, filling strips 404 are inserted into the four vertical grooves 1 206 and the four vertical grooves 207, and a connecting column 402 is fixed on the upper side of each filling strip 404, and multiple connecting columns 402 are welded to the cross 401, a straight iron wire 302 can be inserted between the relative vertical grooves 1 206 and the vertical grooves 2 207, and then the four straight iron wires 302 are also arranged in the annular space, and then the four vertical grooves 1 206 and the four vertical grooves 2 207 are inserted through multiple filling strips 404, and then the redundant positions of the vertical grooves 1 206 and the vertical grooves 2 207 are filled, and the strength of the annular plastic is further improved by the four straight iron wires 302.
[0038] like Figure 5-8 As shown, this example can achieve the effect that the four outer filling strips 404 and the four inner filling strips 404 are in the correct position after being inserted into the four vertical slots 1 206 and the four vertical slots 2 207 .
[0039] Since the limiting pins 403 are fixed on the filling strips 404 located on the outside, the multiple limiting pins 403 are all located on the outside of the outer cylinder 201, and the multiple filling strips 404 are limited by the multiple limiting pins 403 respectively, so that the four outer filling strips 404 and the four inner filling strips 404 are in the correct position after being inserted into the four vertical slots 1 206 and the four vertical slots 207.
[0040] like Figure 5-8 As shown, this example can achieve the effect of smoothing the plastic on the upper side of the annular space.
[0041] Since the plastic molding equipment also includes two pressing plates 405, the two pressing plates 405 are pressed on the upper side of the outer cylinder 201 and the inner cylinder 208, and an injection port 406 is provided on the pressing plate 405. Two sliding rods 407 are fixed on each pressing plate 405, and multiple sliding rods 407 are slidably connected to the cross 401. The sliding rod 407 can slide vertically on the cross 401, so that the two pressing plates 405 can slide vertically, and then the two pressing plates 405 are pressed on the upper side of the annular space, so as to smooth the plastic on the upper side of the annular space, and the molten plastic is conveniently injected into the annular space through the injection port 406.
[0042] like Figure 7-8 As shown, this example can achieve the effect of causing the pressing plate 405 to press on the upper sides of the outer cylinder 201 and the inner cylinder 208 .
[0043] Since compression springs are sleeved on the plurality of slide bars 407 , and the compression springs are located between the cross 401 and the pressure plate 405 , the compression springs apply downward force to the pressure plate 405 , so that the pressure plate 405 is pressed against the upper sides of the outer cylinder 201 and the inner cylinder 208 .
[0044] like Figure 1-10 As shown, this example can achieve the effect of making the plastic fill the annular space.
[0045] Since the lower side of the circular plate 101 is connected to the support seat 501 by screws, two track rods 503 are arranged on the left and right, and the two track rods 503 are fixed between the two door-shaped frames 502, the left and right ends of the support seat 501 are respectively slidably connected to the two track rods 503, and the front and rear ends of the track rods 503 are sleeved with compression springs, and a convex piece 506 is welded on the lower side of the support seat 501, and a hydraulic cylinder is fixed on one of the door-shaped frames 502, and the movable end of the hydraulic cylinder is against the convex piece 506. The hydraulic cylinder moves back and forth to drive the convex piece 506 and the support seat 501 to move back and forth, thereby driving the support seat 501 to slide back and forth on the two track rods 503, and then driving the circular plate 101, the outer cylinder 201 and the inner cylinder 208 to slide back and forth, thereby shaking the plastic in the annular space, so that the plastic fills the annular space.
[0046] like Figure 9-10 As shown, this example can achieve the effect of pressing eight filling strips 404 against the outer cylinder 201 and the inner cylinder 208 .
[0047] Since the support seat 501 is vertically slidably connected with an L-shaped rod 504, the L-shaped rod 504 is pressed on the upper side of the cross 401, and the support seat 501 is threadedly connected with a fastening screw 505, the fastening screw 505 is pressed on the L-shaped rod 504, and the fastening screw 505 is pressed on the L-shaped rod 504, so that the eight filling strips 404 are pressed on the outer cylinder 201 and the inner cylinder 208, and the two pressure plates 405 are pressed on the outer cylinder 201 and the inner cylinder 208.
