Description
Technical Field
[0001] This invention relates to the field of plastic molding technology, and more specifically, to a plastic shaping device for artificial flowers. Background Technology
[0002] Artificial flowers, also known as simulated flowers, are floral decorations made by imitating fresh flowers using materials such as fabric, yarn, silk, and plastic. In the production of plastic artificial flowers, shaping is a crucial step, determining the final product's form and texture.
[0003] Currently, common artificial flower plastic shaping devices on the market typically include an upper mold, a lower mold, and cooling channels located inside the mold. Their working principle is as follows: after molten plastic raw material is injected into the closed cavity, a cooling medium (such as water or oil) is introduced into the cooling channels inside the mold, causing the molten plastic in the cavity to rapidly cool and solidify, thereby obtaining the desired shape of the plastic flower product.
[0004] However, in actual use, the cooling medium flowing inside the existing shaping device is usually in a laminar flow state in the flow channel. The fluid velocity near the flow channel wall is low, and the heat exchange efficiency is limited, resulting in a slow cooling speed and a long shaping cycle. In addition, because the cooling medium is prone to generating temperature gradients when flowing in the flow channel, the cooling rate of different areas of the mold cavity is inconsistent, which can easily cause uneven local cooling of plastic products and affect the appearance simulation and dimensional accuracy of artificial flower products. Summary of the Invention

[0033] Example 1, please refer to Figures 1-11 The present invention provides the following technical solution: an artificial flower plastic shaping device, specifically comprising a cooling mechanism 1 and a shaping mechanism 2 fixedly mounted thereon. The shaping mechanism 2 includes a lower mold component 3 fixedly mounted on the cooling mechanism 1, an upper mold component 4 slidably fitted on the cooling mechanism 1, several baffles 5 rotatably fitted on the lower mold component 3, and a driving component 6 slidably fitted on the lower mold component 3. The lower mold component 3 includes a lower mold 301 fixedly mounted on the cooling mechanism 1, a cooling chamber 302 disposed inside the lower mold 301, several positioning sleeves 303 connected to the cooling chamber 302 disposed on one outer side of the lower mold 301, and two symmetrically arranged U-shaped base plates 304 fixed on one outer side of the lower mold 301; the baffles 5 include... The first rotating rod 501 is rotatably fitted inside the positioning sleeve 303 via a rotating sealing assembly. The circumferential side of the first rotating rod 501 is provided with a spiral channel 502 outside the lower mold 301. Several baffles 503 are fixed on the circumferential side of the first rotating rod 501 inside the cooling chamber 302. Several baffle holes 504 are provided through the circumferential side of the baffles 503. The driving component 6 includes a U-shaped reciprocating plate 601 that reciprocates and slides on two U-shaped base plates 304. Several sliding rings 602 are fixed at the top of the U-shaped reciprocating plate 601 and are respectively sleeved on several first rotating rods 501. An extension rod 603 is fixed on the inner wall of the sliding ring 602. A sliding ball 604 that slides with the spiral channel 502 is fixed at the end of the extension rod 603.
[0034] Furthermore, the rotating sealing assembly includes a rolling bearing and a seal. The rolling bearing is embedded in the inner wall of the positioning sleeve 303 near the outer side, and the seal is disposed in the inner wall of the positioning sleeve 303 near the cooling chamber 302. The rolling bearing and the seal are distributed axially along the positioning sleeve 303. The first rotating rod 501 passes through the inner ring of the rolling bearing and the inner hole of the seal in sequence. The rolling bearing is used to bear the radial load of the first rotating rod 501 and maintain its rotational coaxiality. The seal is used to prevent the coolant in the cooling chamber 302 from leaking outward along the first rotating rod 501. The seal is a mechanical seal, which includes a rotating ring fixedly sleeved on the first rotating rod 501, a stationary ring fixedly installed on the inner wall of the positioning sleeve 303, and an elastic compensation element disposed between the rotating ring and the stationary ring. The end faces of the rotating ring and the stationary ring are tightly fitted under the thrust of the elastic compensation element. The spiral channel 502 has closed end walls at both ends to limit the sliding stroke of the sliding ball 604; the cooling mechanism 1 includes a liquid storage tank 101, a first vertical rod 102 is fixed to the top of the liquid storage tank 101, a first sleeve 103 is fixed to the top of the first vertical rod 102, a second vertical rod 104 is fixed to the outer side of the first sleeve 103, a second sleeve 105 is fixed to the top of the second vertical rod 104, a second rotating rod 106 is rotatably fitted inside the second sleeve 105 through a bearing, a limiting circular plate 107 is fixed to the end of the second rotating rod 106, a reciprocating screw 108 is fixed to the end of the limiting circular plate 107, and a limiting nut 109 is threadedly connected to the end of the reciprocating screw 108; a vertical extension plate 605 is fixed to the outer side of a sliding ring 602 located in the middle, and a reciprocating sleeve 606 adapted to the reciprocating screw 108 is fixed to the end of the vertical extension plate 605.
[0035] The specific application of this embodiment is as follows: After the mold closing operation is performed in the initial state, the operator first injects the molten plastic raw material into the cavity formed by the closing of the upper mold 401 and the lower mold 301 through the raw material feed pipe 402 at the top of the upper mold part 4; the upper mold 401 slides down along the four uprights 129 under the drive of the external driving device (such as a hydraulic cylinder or air cylinder not mentioned in this embodiment) until it is tightly fitted with the lower mold 301, completing the mold closing action and filling the cavity with plastic raw material.
[0036] While the coolant circulates, to improve heat exchange efficiency, the drive unit 6 starts working, causing the U-shaped reciprocating plate 601 to reciprocate linearly on the two U-shaped base plates 304. Its reciprocating sliding stroke is precisely limited by the lead and rotation angle of the reciprocating screw 108, and this stroke is less than the effective length of the spiral channel 502. When the U-shaped reciprocating plate 601 moves, its sliding ring 602 drives the extension rod 603 and the sliding ball 604 to move synchronously. Because the sliding ball 604 reciprocates and slides within the spiral channel 502 on the first rotating rod 501, and both ends of the spiral channel 502 are respectively provided with closed end walls, to prevent rigidity failure during the reciprocating process, the maximum linear reversing stroke of the reciprocating sleeve 606 reciprocating on the reciprocating screw 108 is set to... The internal straight-line distance between the closed end walls at both ends of the spiral channel 502 is set as The journey made Furthermore, polyurethane elastic buffer pads are fixedly embedded on the inner surfaces of each closed end wall. This structure ensures that the sliding ball 604 always maintains a safe gap between the normal reciprocating commutation pole and the closed end wall. The buffer pads absorb the minor overshoot caused by the accumulation of assembly errors, preventing it from jamming due to rigid interference during reciprocating sliding. In this way, the linear reciprocating motion of the sliding ball 604 is converted into the reciprocating rotational motion of the first rotating rod 501. The rotation of the first rotating rod 501 will drive the turbulence fan 503 located in the cooling chamber 302 to rotate synchronously, thereby agitating the coolant in the cooling chamber 302 in both forward and reverse directions, thereby breaking the laminar boundary layer of the coolant near the heat exchange surface, forming forced convection, and improving the heat transfer efficiency. Meanwhile, the turbulence holes 504 on the turbulence fan 503 reduce the resistance of the turbulence fan 503 when rotating in the coolant, and allow some coolant to pass through the turbulence holes 504, forming local jet and vortex disturbances. This enhances the micro-mixing of the coolant inside the cooling chamber 302, avoiding problems such as insufficient cooling, deformation, and uneven thickness in the artificial flower product. This further strengthens the heat transfer between the coolant and the inner wall of the lower mold 301, thereby accelerating the cooling and shaping speed of the plastic product. After the plastic product has completely cooled and solidified, the upper mold 401 slides upward and resets, realizing mold opening. The operator then removes the formed artificial flower plastic product, thus completing a complete shaping cycle.

A pin 127 is fixed, and a swing arm 128 is rotatably fitted to one side of the second hinge seat 123 on the circumferential side of the pin 127. Four vertically distributed uprights 129 are fixed to the top of the liquid storage tank 101, and mounting base plates 130 are fixed to the circumferential sides of each of the four uprights 129. Four insertion holes are opened through the lower mold 301, which are respectively inserted into the four uprights 129. The bottom of the lower mold 301 is fixedly connected to the top of the mounting base plate 130. A first circulation pipe 305 connected to the cooling chamber 302 is provided on one outer side of the lower mold 301. A first connector 306 is connected to the end of the first circulation pipe 305. A second circulation pipe connected to the cooling chamber 302 is provided on the opposite outer side of the lower mold 301. A second connector 308 is connected to the end of the ring pipe 307 and the second circulation pipe 307; a liquid extraction pipe 131 adapted to the first connector 306 is connected to the circumferential side of the piston pipe 115; a liquid inlet pipe 132 adapted to the second connector 308 is connected to the outer side of the liquid storage tank 101; a first one-way valve is provided on the liquid extraction pipe 131, a second one-way valve is provided on the vertical guide pipe 114, and a third one-way valve is provided on the liquid inlet pipe 132; the first one-way valve only allows coolant to flow from the piston pipe 115 to the first circulation pipe 305, the second one-way valve only allows coolant to flow from the liquid storage tank 101 to the piston pipe 115, and the third one-way valve only allows coolant to flow from the second circulation pipe 307 to the liquid storage tank 101;The upper mold component 4 includes an upper mold 401 that slides through and is slidably fitted onto four uprights 129.

The telescopic end of the telescopic cylinder 134 is fixedly connected to the fixing sleeve 404.
[0038] The specific application of this second embodiment is as follows: Based on the first embodiment, this embodiment further realizes the coordinated automated operation of mold closing, turbulence-enhanced cooling, and forced circulation of coolant during the shaping process. During use, it should be noted that some special plastic artificial flowers will release flammable and explosive gases during the melt injection molding stage. The molding workshop is a high-explosion-proof area, and the number of electrical ignition sources must be minimized as much as possible. Therefore, this embodiment uses a single-point drive motor 110 as the sole power source. Through the distribution of purely mechanical components (gear transmission and crank-slider linkage), the single-axis rotational power is synchronously converted into the reciprocating pumping force of the piston 117 at the liquid supply end and the alternating stirring force of the turbulence fan 503 at the heat dissipation end. This design ensures cooling efficiency while reducing the explosion-proof safety hazards and wiring complexity caused by distributing multiple independent motors at the mold end. Before the shaping work begins, the telescopic cylinder 134 is activated. Its telescopic end pulls the extension top plate 403 through the fixed sleeve 404, thereby driving the upper mold 401 to slide downwards along the four uprights 129, completing the mold closing with the lower mold 301. Subsequently, the operator injects molten plastic material into the closed cavity through the raw material feed pipe 402.
[0039] After the operator injects molten plastic material into the closed cavity through the raw material feed pipe 402, the drive motor 110 starts, and its output shaft drives the drive shaft 111 to rotate. The first bevel gear 112 on the drive shaft 111 meshes with the fourth bevel gear 125, transmitting power to the third rotating rod 124, which drives the rotating disk 126 to rotate. The pin 127 at the off-center end of the rotating disk 126 drives the second hinge seat 123 to reciprocate within the cross groove 122 of the U-shaped plate 121 via the swing arm 128. This, in turn, pulls the slide rod 118 via the lifting arm 120 and the first hinge seat 119, causing the piston 117 to reciprocate within the piston tube 115. As a necessary error-proof design to avoid mechanical impact damage, the rotational eccentricity radius of the pin 127 on the rotating disk 126 is set to be... The effective cavity height between the bottom wall of the piston tube 115 and the top limiting point is: The height of piston 117 itself is The device strictly meets the requirements in terms of size and assembly. This ensures that the maximum longitudinal stroke, converted from eccentric rotation, always remains within the safe cavity of the piston tube 115, preventing the piston 117 from impacting the tube bottom or dislodging from the tube opening when it reaches the upper or lower dead center. During the reciprocating piston motion of the piston 117 within the piston tube 115, a first check valve is installed on the suction pipe 131, allowing coolant to flow only from the piston tube 115 towards the first circulation pipe 305. Furthermore, a second check valve is installed on the vertical guide pipe 114, allowing coolant to flow only from the reservoir 101 towards the piston tube 115. Flow; a third check valve is provided on the inlet pipe 132, which only allows coolant to flow from the second circulation pipe 307 to the storage tank 101. Therefore, under the guidance of the above-mentioned multiple check valves, when the piston 117 moves towards the vertical guide pipe 116, a negative pressure is formed inside the piston pipe 115. The cooling medium in the storage tank 101 is drawn into the piston pipe 115 through the vertical guide pipe 114 and the second check valve. At this time, the first check valve and the third check valve are in the closed state to prevent coolant from being drawn back from the first circulation pipe 305 or the inlet pipe 132; when the piston 117 moves towards the vertical guide pipe 116, a negative pressure is formed inside the piston pipe 115. When plug 117 is squeezed in the direction of the guide vertical pipe 114, the cooling medium in piston pipe 115 is transported under pressure to the cooling chamber 302 inside lower mold 301 through the liquid extraction pipe 131, the first one-way valve, the first connector 306, and the first circulation pipe 305. At this time, the second one-way valve is in the closed state to prevent the coolant from being forced back into the storage tank 101. After the medium has completed heat exchange and temperature rise in the cooling chamber 302, it flows back to the storage tank 101 under pressure through the second circulation pipe 307, the second connector 308, the liquid inlet pipe 132, and the third one-way valve. Through the synergistic effect of the aforementioned one-way valve, the reciprocating motion of the piston 117 continuously drives the coolant to form a one-way, closed-loop forced circulation flow between the reservoir 101 and the cooling chamber 302. To ensure the safety and stability of the closed-loop pipeline, an expansion tank and an automatic exhaust and pressure relief valve (not shown in the figure) are connected to the top of the outer wall or the top of the side wall of the reservoir 101. This is used to automatically discharge the air in the pipeline during the initial liquid injection of the system to prevent air blockage, and to accommodate the volume expansion of the cooling medium due to heating during the circulation process, so as to avoid the closed pipeline system from rupturing due to a sudden increase in internal pressure.
[0040] During the coolant circulation, the second bevel gear 113 and the third bevel gear 135 on the drive shaft 111 mesh, driving the second rotating rod 106 and the reciprocating screw 108 to rotate. The reciprocating screw 108, through a matching reciprocating sleeve 606, drives the vertical extension plate 605 and the sliding ring 602 fixed thereto, thereby causing the U-shaped reciprocating plate 601 to reciprocate linearly on the two U-shaped base plates 304. When the U-shaped reciprocating plate 601 moves, the sliding ring 602 on it drives the extension rod 603 and the sliding ball 604 to move synchronously. Since the sliding ball 604 is slidably fitted into the helical groove 502 on the first rotating rod 501, the linear reciprocating motion of the sliding ball 604 is converted into the reciprocating rotational motion of the first rotating rod 501. The rotation of the first rotating rod 501 drives the turbulence fan 503 located in the cooling chamber 302 to rotate synchronously, forcibly agitating the coolant in the cooling chamber 302, breaking the laminar boundary layer of the coolant near the heat exchange surface, and forming forced convection. At the same time, the turbulence holes 504 opened on the turbulence fan 503 allow some coolant to pass through the turbulence fan 503, forming a local pressure difference and jet effect on both sides of the turbulence fan 503, generating auxiliary vortex disturbance, which helps to reduce the flow dead zone inside the cooling chamber 302, making the temperature relatively uniform throughout the cooling chamber 302, thereby accelerating the cooling and shaping speed of plastic products.
[0041] After the plastic product has completely cooled and solidified, the telescopic cylinder 134 reverses its movement, pushing the extension top plate 403 through the fixed sleeve 404, which in turn drives the upper mold 401 to slide upwards and reset along the upright 129, thus opening the mold. The operator then removes the molded artificial flower plastic product, completing a full shaping cycle.
