Description

Technical Field

[0001] The utility model relates to the technical field of silicone processing, in particular to a pressing and forming device for silicone processing. Background Technique

[0002] Processed products mainly made of silicone are called silicone products. Silicone is a porous substance with different particle sizes appropriately dehydrated from silicic acid gel. It has an open porous structure, can adsorb many substances, and is a good desiccant, adsorbent and catalyst carrier.

[0003] In the prior art, after the silicone product is pressed and formed, it needs to be taken out of the mold and then cooled. This method increases the processing procedures of the silicone product, thereby reducing the processing efficiency of the silicone product. Therefore, in order to solve such problems, we propose a pressing and forming device for silicone processing. Summary of the Utility Model

[0004] A pressing and forming device for silicone processing proposed by the utility model solves the problem that it is difficult to effectively cool and cool the pressed and formed silicone product synchronously during the existing silicone pressing and forming process, thereby reducing the processing efficiency of the silicone product.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A pressing and forming device for silicone processing, including a base, a bracket arranged in a U-shape is fixedly installed at the top end of the base, and a circular groove is opened at the top end of the base. A fixed seat is installed in the circular groove, and a fixed mold is installed at the top end of the fixed seat;

[0007] The inner wall of the horizontal section of the bracket is installed with a cylinder, and the end of the piston rod of the cylinder is fixedly installed vertically downward with a water tank. The bottom end of the water tank is fixedly installed with a movable plate. A rotating seat moving in the vertical direction is installed between the inner walls on both sides of the bracket. Three hinge rods distributed in a circular array are installed between the bottom end of the movable plate and the top end of the rotating seat. A movable mold is installed at the bottom end of the rotating seat, and a conduit rotatably connected to the rotating seat is fixedly installed at the top end of the movable mold. The conduit is slidably penetrated through the movable plate and the bottom end of the water tank, and two symmetrically distributed liquid inlets are opened at the top end of the circumferential side wall of the conduit, and four liquid outlets distributed in a circular array are opened at the bottom end of the circumferential side wall of the conduit;

[0008] An upper liquid storage cavity arranged in a ring shape and four diversion cavities distributed in a circular array are opened inside the rotating seat, and the diversion cavities are communicated with the upper liquid storage cavity. A lower liquid storage cavity arranged in a ring shape is opened inside the fixed seat.

[0009] Furthermore, both sides of the movable plate are fixedly connected with symmetrically distributed limit blocks, and the inner walls on both sides of the bracket are provided with symmetrically distributed limit grooves, and the limit blocks are slidably installed inside the limit grooves. The sliding of the limit blocks inside the limit grooves can make the sliding of the movable plate in the vertical direction more stable, avoiding the occurrence of offset displacement.

[0010] Furthermore, two symmetrically distributed limit plates are fixedly connected to the bottom end of the movable plate, a limit ring is fixedly sleeved on the circumferential outer wall of the rotating seat, and arc grooves for the limit rings to rotate are provided on the sides of the two limit plates close to each other. The setting of the limit plates can ensure that the rotating seat will not have horizontal deviation and displacement when moving up and down, and the limit rings and arc grooves can ensure the stability of the rotating seat during rotation.

[0011] Furthermore, an upper liquid guide hole connected to the upper liquid storage chamber is formed at the bottom end of the rotating seat, and a lower liquid guide hole connected to the lower liquid storage chamber is formed at the top end of the fixed seat, and the number of the upper liquid guide holes and the lower liquid guide holes are correspondingly arranged, and the hole diameters are consistent. Through the arrangement of the upper liquid guide holes and the lower liquid guide holes, after the silicone is pressed and formed, the coolant is evenly wrapped in the fixed mold and the outside of the fixed mold, and the silicone product pressed and formed in the mold cavity is cooled and cooled in multiple directions and positions.

[0012] Furthermore, a ring-shaped water diversion groove is provided at the top of the fixing seat, and the lower liquid guide hole is located inside the water diversion groove. The setting of the water diversion groove can effectively avoid the overflow and waste of water that occurs before the upper liquid guide hole and the lower liquid guide hole are aligned.

[0013] Furthermore, a return spring column is fixedly installed on the inner wall of the top end of the water tank, and the bottom end of the return spring column is fixedly connected to the top end of the conduit. The setting of the return spring column can assist the conduit to be quickly reset, thereby avoiding the coolant inside the water tank continuing to enter the conduit through the liquid inlet due to untimely reset of the conduit when the movable mold and the fixed mold are separated, thereby causing a waste of coolant.

[0014] Furthermore, a return hose is installed between the lower liquid storage chamber and the inside of the water tank, and the coolant can be reused through the arrangement of the return hose.

[0015] The beneficial effects of the utility model are:

[0016] The cylinder pushes the water tank and the movable plate as a whole, thereby synchronously driving the limit plate, the rotating seat and the movable mold to move downward, so that the movable mold cooperates with the fixed mold to perform a compression molding operation on the silicone, and as the cylinder continues to push the water tank, the movable plate pushes the hinge rod, so that the hinge rod drives the rotating seat to rotate, so that the upper liquid guide hole on the rotating seat is aligned with the lower liquid guide hole on the fixed seat, and the guide cavity is aligned with the liquid outlet on the conduit. In the process of the movable plate continuing to move downward, the movable mold fits with the fixed mold, so that the fixed mold and the conduit are in the vertical direction. The position remains unchanged, at this time the catheter squeezes the reset spring column, and the liquid inlet on the catheter enters the inside of the water tank and is connected with the inside of the water tank, the water in the water tank enters the catheter through the liquid inlet, and then enters the diversion cavity through the liquid outlet, and then enters the upper liquid storage cavity, and the upper liquid guide hole and the lower liquid guide hole are aligned, so that the water used for cooling can synchronously enter the lower liquid storage cavity, thereby realizing synchronous cooling treatment of the pressed silicone, and the setting of the reflux hose can make the cooling coolant flow back to the water tank for reuse.

DETAILED DESCRIPTION

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0024] Referring to Figure 1 and Figure 4 , a pressing and forming device for silicone processing, including a base 1, a bracket 2 arranged in a U-shape is fixedly installed at the top end of the base 1, and a circular groove is opened at the top end of the base 1. A fixed seat 12 is installed in the circular groove, and a fixed mold 15 is installed at the top end of the fixed seat 12.

[0025] Referring to the figure and Figure 4 , a cylinder 3 is installed on the inner wall of the top end of the horizontal section of the bracket 2, and a water tank 4 is fixedly installed at the end of the piston rod of the cylinder 3 in a vertically downward direction. A movable plate 5 is fixedly installed at the bottom end of the water tank 4. Limiting blocks 23 are symmetrically distributed and fixedly connected to both sides of the movable plate 5. Limiting grooves 9 are symmetrically distributed and opened on the inner walls of both sides of the bracket 2, and the limiting blocks 23 are slidably installed inside the limiting grooves 9. The sliding of the limiting blocks 23 inside the limiting grooves 9 can make the sliding of the movable plate 5 in the vertical direction more stable, avoiding the phenomenon of deviation and displacement.

[0026] Referring to Figure 1-Figure 4 , a rotating seat 7 moving in the vertical direction is installed between the inner walls of both sides of the bracket 2. Two symmetrically distributed limiting plates 8 are fixedly connected to the bottom end of the movable plate 5. A limiting ring 10 is fixedly sleeved on the circumferential outer wall of the rotating seat 7, and arc-shaped grooves for the limiting ring 10 to rotate are opened on the side of each of the two limiting plates 8 close to each other. The arrangement of the limiting plates 8 can ensure that the rotating seat 7 does not have deviation and displacement in the horizontal direction when moving up and down, and the limiting ring 10 and the arc-shaped grooves can ensure the stability of the rotating seat 7 when rotating.

[0027] Referring to Figure 1-Figure 5 , three hinge rods 11 distributed in a circular array are installed between the bottom end of the movable plate 5 and the top end of the rotating seat 7. A movable mold 16 is installed at the bottom end of the rotating seat 7, and a conduit 6 rotatably connected to the rotating seat 7 is fixedly installed at the top end of the movable mold 16. The conduit 6 is slidably penetrated through the bottom end of the movable plate 5 and the water tank 4. A reset spring column 19 is fixedly installed on the inner wall of the top end of the water tank 4, and the bottom end of the reset spring column 19 is fixedly connected to the top end of the conduit 6. The setting of the reset spring column 19 can assist the conduit 6 to quickly reset, avoiding the phenomenon of coolant waste caused by the coolant in the water tank 4 continuing to enter the conduit 6 through the liquid inlet 25 due to the untimely reset of the conduit 6 when the movable mold 16 and the fixed mold 15 are separated. Two symmetrically distributed liquid inlets 25 are opened at the top end of the circumferential side wall of the conduit 6, and four liquid outlets 24 distributed in a circular array are opened at the bottom end of the circumferential side wall of the conduit 6;

[0028] Reference Figure 1-Figure 4 The rotating seat 7 is provided with an upper liquid storage chamber 21 arranged in an annular shape and four flow guide chambers 22 distributed in an annular array, and the flow guide chamber 22 is communicated with the upper liquid storage chamber 21. The fixed seat 12 is provided with a lower liquid storage chamber 20 arranged in an annular shape. The bottom end of the rotating seat 7 is provided with an upper liquid guide hole 17 communicated with the upper liquid storage chamber 21. The top end of the fixed seat 12 is provided with a lower liquid guide hole 14 communicated with the lower liquid storage chamber 20. The number of the upper liquid guide holes 17 and the number of the lower liquid guide holes 14 are corresponding, and the apertures are consistent. The arrangement of the liquid guide hole 17 and the lower liquid guide hole 14 enables the coolant to be evenly wrapped around the outside of the fixed mold 15 and the movable mold 16 after the silicone is pressed and formed, and the silicone product pressed and formed in the mold cavity is cooled and cooled in multiple directions and positions. A ring-shaped water guide groove 13 is provided at the top of the fixed seat 12, and the lower liquid guide hole 14 is located inside the water guide groove 13. The arrangement of the water guide groove 13 can effectively avoid the overflow and waste of water that occurs before the upper liquid guide hole 17 and the lower liquid guide hole 14 are aligned.

[0029] Reference Figure 3 A return hose 18 is installed between the lower liquid storage chamber 20 and the inside of the water tank 4. The return hose 18 can be arranged so that the coolant can be reused.

[0030] When the pressing and molding equipment for silicone processing is used, the silicone raw material to be pressed is first introduced into the mold cavity of the fixed mold 15, and the water tank 4 is filled with coolant. At this time, the liquid inlet 25 of the conduit 6 is located outside the water tank 4, and the coolant inside the water tank 4 will not enter the conduit 6 through the liquid inlet 25, that is, the coolant inside the water tank 4 is in a static state, and then the cylinder 3 is started, and the water tank 4 and the movable plate 5 are pushed downward by the cylinder 3. The movable plate 5 drives the limit block 23 to slide in the limit groove 9, and at the same time drives the limit plate 8, the conduit 6, the hinged rod 11, the limit ring 10, the rotating seat 7 and the movable mold 16 to move downward. When the movable mold 16 contacts the fixed mold 15, the silicone raw material can be pressed to be formed.

[0031] The cylinder 3 continues to push downward, at this time the movable mold 16 and the conduit 6 are fixed, and the water tank 4 will continue to push the movable plate 5, so that the movable plate 5 pushes the hinge rod 11, and the hinge rod 11 pushes the rotating seat 7 to rotate around the movable mold 16 and the conduit 6, and drives the limit ring 10 to rotate inside the arc groove, and at the same time there is an upward displacement inside the arc groove until the upper liquid guide hole 17 on the rotating seat 7 is aligned with the lower liquid guide hole 14 on the fixed seat 12, and the guide cavity 22 on the rotating seat 7 is aligned with the liquid outlet 24 on the conduit 6. At this time, the conduit 6 will synchronously squeeze the reset spring column 19, and the liquid inlet 25 on the conduit 6 enters the water tank. 4, the coolant inside the water tank 4 enters the inside of the conduit 6 through the liquid inlet 25, and then enters the guide cavity 22 through the liquid outlet 24 on the conduit 6, and then enters the upper liquid storage cavity 21 through the guide cavity 22, and then enters the lower liquid storage cavity 20 through the upper liquid guide hole 17 and the lower liquid guide hole 14, so that the coolant wraps the movable mold 16 and the fixed mold 15 in multiple directions and multiple parts, thereby being able to synchronously cool and cool the pressed silicone products to improve the processing efficiency of the silicone products, and the used coolant is then returned to the water tank 4 through the reflux hose 18 for reuse, and a reflux pump needs to be added during actual use.
