Description

Technical Field

[0001] The invention relates to the technical field of EPS foaming and molding, in particular to an EPS plastic foam mold. Background Art

[0002] EPS foam molding refers to the process of expanding polystyrene raw material particles into a lightweight foam material with a porous structure through heating and the action of a foaming agent. In this process, the polystyrene particles are decomposed under specific temperature and pressure conditions to produce gas, causing the inside of the particles to expand to form a closed-cell structure. After cooling and solidification, EPS foam products with a certain shape and size are finally formed in the mold. EPS plastic foam molds are divided into simple cavity molds suitable for simple shapes, multi-cavity molds that can produce multiple foam products at the same time, and molds with cooling systems. When producing complex plastic foam models, simple cavity molds are required to make foam products, and after molding, the foam products are molded by cutting and processing equipment.

[0003] After the EPS foam product is foamed and molded, it is necessary to manually remove the EPS foam product formed in the mold cavity. Since the plastic foam is heated and pressurized inside the mold, the molded EPS foam product forms a certain degree of adhesion or a large pressure with the mold cavity wall, which makes it inconvenient to demold the EPS foam product. When the mold is inconvenient to demold, it is necessary to manually use external tools to assist in demolding the EPS foam product formed in the mold. Demolding the plastic mold by manually using external auxiliary tools not only increases the production cycle of each EPS foam product, but also makes it inconvenient for manual use of the mold, thereby reducing the demolding effect and use effect of the mold. To this end, we propose an EPS plastic foam mold.

[0004] Combining the above problems, we will find that it is difficult to avoid the above problems at the same time when using the existing EPS plastic foam molds on the market, and even if they can be solved, they need to be solved with the cooperation of external tools, which cannot achieve the desired effect. Therefore, we propose an EPS plastic foam mold. Summary of the invention

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0022] See also Figure 1-12The present invention provides a technical solution: an EPS plastic foam mold, comprising a main body mechanism 1, the main body mechanism 1 comprises a support frame 11, the inner wall of the support frame 11 is fixedly connected with a lower mold 14, the inner wall of the support frame 11 is fixedly connected with two hydraulic cylinders 12, the telescopic ends of the two hydraulic cylinders 12 are commonly fixedly connected with an upper mold 13, the bottom surface of the upper mold 13 is in contact with the upper surface of the lower mold 14, and the interior of the lower mold 14 is provided with a high-efficiency demoulding mechanism 2; The efficient demoulding mechanism 2 comprises a separation unit 21 . The separation unit 21 is located inside the lower mold 14 . The separation unit 21 is used to lower the contact surface of the lower mold 14 .

[0023] As a further limitation of the efficient demoulding mechanism 2 of the present invention, the separation unit 21 includes four inner cavities 2113, the inner wall of each inner cavity 2113 is provided with a sealing groove 2106, the interior of each sealing groove 2106 is slidably connected with a closed shell 2103, the outer surface of each closed shell 2103 is fixedly connected with two electric telescopic rods 2101, the outer surface of each electric telescopic rod 2101 is fixedly connected to the inner wall of the lower mold 14, the inner wall of each closed shell 2103 is fixedly connected with two first micro electric push rods 2110, the telescopic end of each first micro electric push rod 2110 is fixedly connected with a connecting block 2109, a movable plate 2108 is arranged inside each closed shell 2103, the upper surface of each connecting block 2109 is fixedly connected to the bottom surface of the movable plate 2108, a side surface of each movable plate 2108 is fixedly connected with a plurality of identical separation heads 2104, and the inner wall of each lower mold 14 is provided with A plurality of identical separation holes 2114, each separation head 2104 is located outside the separation hole 2114, and the initial state of the separation head 2104 and the separation hole 2114 is a completely embedded state, and the outer surface of each closed shell 2103 is fixedly connected with a sealing gasket 2105, and the outer surface of each movable plate 2108 is provided with a plurality of identical card slots 2111. By setting the separation unit 21, the adhesion surface between the EPS foam product and the mold cavity wall can be effectively reduced, thereby reducing the adhesion force of the EPS foam product inside the mold cavity wall, making it convenient to demould. When demoulding, the contact surface with the EPS foam product is reduced by the inside of the mold to facilitate demoulding. It is not only convenient for manual demoulding, but also effectively increases the functionality inside the mold, increases the overall use effect of the mold, and can avoid the problem of manual demoulding of the plastic mold using external auxiliary tools, which is time-consuming and labor-intensive, and increases the production cycle of EPS foam products. The outer surface of each sealing shell 2103 is fixedly connected with a rubber pad 2102, and the outer surface of each rubber pad 2102 is in contact with the inner wall of the sealing groove 2106. The rubber pad 2102 can increase the buffering of the surface of the sealing shell 2103 to prevent damage caused by vibration; Two stabilizing grooves 2112 are provided on the inner wall of each closed shell 2103, and the outer surface of each movable plate 2108 is fixedly connected to two stabilizing plates 2107. The outer surface of each stabilizing plate 2107 is slidably connected to the inside of the stabilizing groove 2112. Through the stabilizing groove 2112 and the stabilizing plate 2107, the sliding stability of the movable plate 2108 can be increased to prevent the occurrence of offset instability.

[0024] The specific implementation method of this embodiment is as follows: first, the hydraulic cylinder 12, the electric telescopic rod 2101 and the first micro electric push rod 2110 are started by an external power supply. When the EPS plastic foam needs to be processed, during processing, the initial state of the separation head 2104 and the separation hole 2114 is in a completely embedded state, and the EPS plastic foam is directly placed in the lower mold 14, and then the upper mold 13 is driven by the hydraulic cylinder 12 to seal the lower mold 14. When the EPS plastic foam needs to be taken out and demolded, the upper mold 13 is directly driven upward by the hydraulic cylinder 12 to move, which is convenient for manual demolding. If the EPS foam product is not convenient to demold, the electric telescopic rod 2101 is directly used to drive the sealing shell 2103 in the sealing groove 2106. The sealing shell 2103 drives the separation head 2104 to separate from the separation hole 2114 through the movable plate 2108. When the sealing shell 2103 contacts the sealing groove 2106 through the rubber pad 2102, the separation head 2104 separates from the separation hole 2114 and is inside the sealing groove 2106. At this time, the separation head 2104 separates from the inner wall of the mold, which can effectively reduce the contact area between the EPS foamed product and the cavity wall, thereby facilitating the staff to demould the EPS foamed product. The first micro electric push rod 2110 is then used to drive the movable plate 2108 to move downward through the connecting block 2109. The movable plate 2108 stops after contacting the inner wall of the stabilizing groove 2112 through the stabilizing plate 2107, thereby facilitating the use of the high-efficiency demoulding mechanism 2. Example

[0025] See also Figure 1-12 The present invention provides a technical solution: an EPS plastic foam mold. The present invention makes corresponding improvements to the technical problems mentioned in the background technology.

[0026] As a further limitation of the efficient demoulding mechanism 2 of the present invention, the efficient demoulding mechanism 2 further includes an air blowing unit 22, which is located on the inner side of the separation unit 21, and the air blowing unit 22 is used in conjunction with the separation unit 21, and the air blowing unit 22 is used to indirectly separate the foamed product; The air blowing unit 22 includes four air collecting shells 2205, the outer surface of each air collecting shell 2205 is slidably connected to the inside of the closed shell 2103, the outer surface of each air collecting shell 2205 is fixedly connected to a plurality of identical air nozzles 2209, the inner wall of each lower mold 14 is fixedly connected to four air pumps 2204, the output end of each air pump 2204 is fixedly connected to an air collecting pipe 2206, one end of each air collecting pipe 2206 passes through the interior of the lower mold 14, one end of each air collecting pipe 2206 is fixedly connected to the outer surface of the air collecting shell 2205, the outer surface of each air collecting shell 2205 is fixedly connected to four second micro electric push rods 2201, the outer surface of each second micro electric push rod 2201 is fixedly connected to the inner wall of the lower mold 14, and each The outer surface of each nozzle 2209 is fixedly connected with a card plate 2208, and the outer surface of each card plate 2208 is slidably connected to the inside of the card groove 2111. By setting the air blowing unit 22, the contact surface of the EPS foam product and the lower mold 14 can be reduced by the separation unit 21, and the contact surface of the EPS foam product can be further reduced by blowing, so that the separation effect of the EPS foam product and the mold is better. After the separation unit 21 is separated, the separation unit 21 and the sealing groove 2106 form a sealed cavity, and the external gas is directly filled into the entire sealed cavity through the air blowing unit 22. The gas acts on the surface of the EPS foam product through the separation hole 2114 through the internal pressure, reducing its adhesion surface, and achieving the effect of further demoulding; Four protective nets 2203 are clamped inside the lower mold 14, and the inner wall of each protective net 2203 is threadedly connected with the inner wall of the lower mold 14 by four self-tapping bolts 2202. The protective nets 2203 and the self-tapping bolts 2202 can be used to conveniently protect and isolate the air pump 2204, thereby reducing safety hazards; The outer surface of each gas collecting pipe 2206 is fixedly connected with a reinforcement ring 2207, and the outer surface of each reinforcement ring 2207 is fixedly connected to the outer surface of the gas collecting shell 2205. The reinforcement ring 2207 can increase the connection of the connecting end of the gas collecting pipe 2206 to prevent it from falling off.

[0027] The specific implementation method of this embodiment is: the second micro electric push rod 2201 and the air pump 2204 are started by an external power supply, and when the movable plate 2108 moves downward inside the closed shell 2103, the slot 2111 on the rear side of the movable plate 2108 can slide on the surface of the slot 2208, and the stability of the nozzle 2209 is ensured by the slot 2208. At this time, the nozzle 2209 is located inside the sealing groove 2106, that is, inside the closed space formed by the closed shell 2103 and the sealing groove 2106. At this time, the second micro electric push rod 2201 is directly used to push the gas collecting shell 2205, and the gas collecting shell 2205 can slide inside the closed shell 2103. When the inner wall of the gas collecting shell 2205 contacts the surface of the closed shell 2103, it stops. At this time, the nozzle 2209 is closer to the closed shell 2103 through the movement of the gas collecting shell 2205. Separation hole 2114, and then directly draw external air through air pump 2204, discharge the air to the inside of air collecting shell 2205 through air collecting pipe 2206, and finally spray it out through nozzle 2209. Since the distance between nozzle 2209 and separation hole 2114 is relatively short, the gas sprayed by nozzle 2209 directly acts on the surface of EPS foamed product, and the contact area between EPS foamed product and the inner wall of mold is reduced by the sprayed gas. As more gas is retained in the closed space formed by closed shell 2103 and sealing groove 2106, the air inside the closed space will also be directly pressurized to squeeze EPS foamed product through separation hole 2114, thereby further reducing the adhesion area of ​​EPS foamed product, further facilitating manual demoulding of EPS foamed product, and increasing demoulding effect.

By setting the vibration replacement mechanism 3, the separation unit 21 and the air blowing unit 22 can be cooperated to effectively demould the EPS foam product completely, and the demoulding effect is further achieved. On the basis of the air blowing unit 22, the vibration replacement mechanism 3 is used to further reduce the contact surface between the auxiliary EPS foam product and the mold.

[0030] The specific implementation method of this embodiment is as follows: the micro motor 304 is started by an external power supply. When further demolding is required on the basis of the efficient demolding mechanism 2, since the vibration enclosure 301 is located inside the lower mold 14 and is a part of the lower mold 14, and the replacement cycle of the vibration enclosure 301 is relatively long, the separation head 2104 can pass through the separation hole 2114 to fill the holes on the vibration enclosure 301, so the separation head 2104 is initially in a state of complete engagement with the inner wall of the vibration enclosure 301, and the micro motor 304 is directly used for rotation. The micro motor 304 can drive the rotating disk 308 to rotate through the transmission shaft 325, and the rotating disk 308 can rotate on the stabilizing shaft 323 through the bearing 324. The extension shaft 307 is directly driven by the extension shaft 308 to rotate. When the extension shaft 307 contacts the fixed plate 321, the extension shaft 307 can directly push the fixed plate 321 so that the fixed plate 321 can be pushed in the direction of the lower mold 14. The fixed plate 321 can directly drive the impact head 318 to enter the through hole 312 and contact the vibration enclosure 301 through the telescopic shaft 319, and the telescopic shaft 319 can drive the connecting plate 320 to slide inside the reset groove 316. At the same time, during the sliding process, the connecting plate 320 directly stretches the reset spring 317. When the extension shaft 307 is separated from the fixed plate 321, the reset spring 317 can directly drive the connecting plate 320 to reset. The connecting plate 320 then drives the fixed plate 321 to reset through the telescopic shaft 319. The cyclic rotation of the extension shaft 307 can make the impact head 318 continuously impact the vibration enclosure 301, so that the vibration enclosure 301 rotates. The vibration generated by the vibration enclosure 301 can effectively further reduce the contact area and adhesion between the surface of the EPS foamed product and the vibration enclosure 301, which is convenient for manual demoulding. The vibration of the vibration enclosure 301 will directly drive the mounting plate 310 to vibrate. During the vibration of the vibration enclosure 301, the EVA shock-absorbing pad 311 is used to reduce the friction between the vibration enclosure 301 and the inner wall of the lower mold 14, which effectively buffers the vibration force generated by it, and avoids the vibration of the vibration enclosure 301 and the inner wall of the lower mold 14. The service life is easily reduced due to friction, and it does not affect the vibration demoulding of the EPS foamed product. The service life is increased. At the same time, the mounting plate 310 is buffered inside the mounting groove 303 through the first rubber shock-absorbing pad 309 on the outside, which effectively reduces the friction between the mounting plate 310 and the mounting groove 303 and protects the mounting plate 310. The second rubber shock-absorbing pad 314 can buffer the vibration enclosure 301 and the upper surface of the mounting plate 310, reduce the wear caused by vibration, and increase the use effect and demolding efficiency of the mold. If the inner wall of the vibration enclosure 301 is uneven, it can be directly disassembled and replaced to ensure the smoothness of the inner wall of the vibration enclosure 301 and prevent the uneven inner wall of the vibration enclosure 301 from affecting the demolding. When the vibration enclosure 301 needs to be replaced, the fixing bolt 313 is directly opened.Take out the limiting top plate 302 and remove it through the hole on the vibration enclosure 301. The vibration enclosure 301 slides upward inside the installation groove 303 through the installation plate 310 to separate the vibration enclosure 301 from the lower mold 14. After installation, it can be installed again through the above disassembly steps, which is convenient for replacing the vibration enclosure 301 and further improves the demoulding effect.
