Technical Field

[0001] The invention relates to the technical field of injection molds, and in particular to an injection mold and a method for facilitating heat conduction. Background Art

[0002] Injection molds that facilitate heat dissipation usually consist of a support table, hydraulic equipment, switches, an upper mold and a lower mold.

[0003] The patent with the patent announcement number CN114986810B relates to an environmentally friendly plastic injection mold, which includes a fixing device and a lifting device arranged on the top of the fixing device, the fixing device includes a fixing mechanism, the fixing mechanism includes a base, the top of the base is provided with an injection molding groove, and the bottom of the injection molding groove is provided with an injection molding tube. When cooling and plasticizing the injection molded part, the patent uses a three-layer water flow structure to reduce the heat inside the injection molded part in sequence, so that the injection molded part will not experience a sudden drop in temperature during the cooling process, which will cause damage to the injection molded part. Compared with the common cooling method, it can ensure the cooling effect of the injection molded part while avoiding damage to the injection molded part due to severe thermal expansion and contraction, and when the lifting block is opened, the water in the inner cavity, the middle cavity and the outer cavity is sequentially added to the surface of the injection molded part, completing the further gradual cooling of the injection molded part, and at the same time, it is easy to demould the injection molded part.

[0004] In the above patent, when the lifting block is opened, water in the inner cavity, the middle cavity and the outer cavity are sequentially added to the surface of the injection-molded part, thereby completing further gradual cooling of the injection-molded part and facilitating demoulding of the injection-molded part. However, it is difficult to prevent the upper mold from colliding and squeezing with the scraper. The collision or squeezing between the upper mold and the scraper will generate a large impact force, resulting in deformation or damage of the upper mold, and further causing quality problems of the injection-molded part due to uneven cooling.

[0009] According to the above technical solution, a dredging assembly for preventing the injection pipe from being blocked is arranged on the right side of the lower mold, a demolding assembly is arranged on the right side of the lower mold. The dredging assembly includes a connecting pipe, an extrusion frame, a gear, an elastic telescopic rod and a connecting groove. The extrusion frame rotates to stir the solidified plastic inside the injection pipe. The connecting pipe is slidably installed on the inner wall of the injection pipe.

The protective plate moves upward to break away from the contact with the protective groove and releases the limit on the free end of the elastic telescopic rod. A No. 2 spring is arranged between the protective plate and the injection molding tube. The protective plate moves upward to squeeze the No. 2 spring. The No. 2 spring is deformed and accumulates force due to the squeezing of the protective plate. After the protective plate is manually released, the No. 2 spring can drive the protective plate to reset.

The right side of the demolding frame is arranged as an inclined surface, and the friction between the linkage rod and the demolding frame can be reduced by the inclined surface of the demolding frame. The demolding frame moves to the right side to reset and hits the semicircular block to generate vibration.

[0014] A method for using an injection mold that facilitates heat dissipation, using the above-mentioned injection mold that facilitates heat dissipation, includes the following steps:

[0016] Step 2: The protection plate is extruded by the scraping plate and moves back towards the support frame.

[0017] Step 3: After the limit of the switch is released, manually press the switch to drive the output end of the hydraulic device to move downward. The downward movement of the output end of the hydraulic device drives the connecting plate to move downward, and the downward movement of the connecting plate drives the upper mold to move downward. The downward movement of the upper mold contacts the lower mold and completes the mold closing.

[0018] Step 4: After the upper mold contacts the lower mold and completes the mold closing, start the external injection molding mechanism to inject the molten plastic into the space between the upper mold and the lower mold through the injection pipe for injection molding operations.

[0019] The present invention provides an injection mold that facilitates heat dissipation. It has the following beneficial effects:

[0020] (1) In this invention, the scraping plate moves forward to contact the lower mold and pushes the residual solid plastic on the top of the lower mold. The scraping plate helps remove the residual plastic, keeping the surfaces of the upper mold and the lower mold clean. This avoids uneven heat accumulation when the plastic cools, facilitating heat dissipation and preventing local overheating. It further reduces the wear and deformation of the upper mold and the lower mold. By aligning the protection hole with the switch, the protection plate releases the limit on the switch. By releasing the limit of the protection plate on the switch, it can ensure the correct movement of the scraping plate and the upper mold, avoiding collisions between the scraping plate and the upper mold, and thus improving the forming accuracy of the product.

[0021] (2) In this invention, the extrusion frame rotates to agitate the solidified plastic inside the injection pipe. The solidified plastic is prone to accumulate or form blockages inside the injection pipe. By the rotation of the extrusion frame, the accumulation of the solidified plastic can be effectively broken, keeping the pipeline unobstructed, thus avoiding blockages and ensuring the smooth progress of the injection molding process.

[0022] (3) In this invention, by manually pushing the protection plate upward, the protection plate moves upward to disengage from the contact with the protection groove and releases the limit on the free end of the elastic telescopic rod. Through the fixing effect of the protection plate, it can ensure that the connection between the injection pipe and the external injection molding mechanism is not loose, thereby reducing the risk of leakage and ensuring the quality of the injection molded parts.

[0023] (4) In this invention, the demolding frame moves away from the demolding disc to extrude and push the stuck product. Through the extrusion of the demolding frame, it can effectively help the product to be demolded smoothly, reduce the occurrence of stuck phenomena, and thus avoid production stagnation caused by jams.

[0024] (5) In this invention, the demolding frame moves to the right to reset and impacts the semi-circular block to generate vibration. The vibration of the demolding frame drives the lower mold to resonate together. Through the impact force and resonance effect generated by the vibration, the demolding process can be further accelerated, thereby improving the stability of the product demolding process.

[0035] A square groove 13 is opened on the top of the support table 1, a protection rod 14 is fixedly installed at the rear side of the support table 1, a protection plate 15 is slidably installed on the circumferential surface of the protection rod 14, a protection hole 16 is opened at the bottom of the protection plate 15, and a switch 17 is fixedly installed at the bottom of the inner wall of the square groove 13. The hydraulic device 3 can be controlled through the switch 17.

[0036] A rack 18 is fixedly installed on the front side of the scraper 12. A first spring is arranged between the protection rod 14 and the protection plate 15. When the protection plate 15 moves towards the support frame 2 to reset, the first spring is compressed. The first spring deforms and stores energy under the extrusion of the protection plate 15. After the protection plate 15 is separated from the contact with the scraper 12, the first spring can drive the protection plate 15 to reset. The switch 17 is electrically connected with the hydraulic device 3. When the protection plate 15 contacts the inner wall of the square groove 13 and the protection hole 16 is aligned with the switch 17, the protection plate 15 releases the limit on the switch 17. By releasing the limit of the protection plate 15 on the switch 17, the correct movement of the scraper 12 and the upper mold 5 can be ensured, avoiding the collision between the scraper 12 and the upper mold 5, and thus improving the forming precision of the product.

[0037] A usage method of an injection mold facilitating heat dissipation, using the above-mentioned injection mold facilitating heat dissipation, includes the following steps:

[0038] Step 1: The servo motor 10 rotates in the reverse direction to drive the lead screw 11 to rotate in the reverse direction. The reverse rotation of the lead screw 11 drives the scraper 12 to move backward and reset. The backward movement and reset of the scraper 12 contact the protection plate 15 and squeeze the protection plate 15;

[0039] Step 2: The protection plate 15 is squeezed by the scraper 12 and moves and resets in the direction close to the support frame 2. The movement of the protection plate 15 in the direction close to the support frame 2 aligns the protection hole 16 with the switch 17. The alignment of the protection hole 16 and the switch 17 enables the protection plate 15 to release the limit on the switch 17;

[0040] Step 3: After the limit of the switch 17 is released, manually press the switch 17 to drive the output end of the hydraulic device 3 to move downward. The downward movement of the output end of the hydraulic device 3 drives the connecting plate 4 to move downward. The downward movement of the connecting plate 4 drives the upper mold 5 to move downward. The downward movement of the upper mold 5 contacts the lower mold 9 and completes the mold closing;

[0041] Step 4: After the upper mold 5 contacts the lower mold 9 and completes the mold closing, start the externally connected injection mechanism to inject the molten plastic into the space between the upper mold 5 and the lower mold 9 through the injection pipe 191 for injection molding operations.

[0042] During the operation of this embodiment: The servo motor 10 rotates to drive the lead screw 11 to rotate. The rotation of the lead screw 11 drives the scraper 12 to move forward. The forward movement of the scraper 12 contacts the lower mold 9 and pushes the solid plastic remaining on the top of the lower mold 9. At the same time, the forward movement of the scraper 12 separates from the contact with the protection plate 15. After the protection plate 15 separates from the contact with the scraper 12, the protection plate 15 moves forward under the elastic force of the first spring. The forward movement of the protection plate 15 causes the protection hole 16 to shift. The shift of the protection hole 16 enables the protection plate 15 to block and limit the switch 17. When the servo motor 10 rotates in the reverse direction to drive the lead screw 11 to rotate in the reverse direction, the reverse rotation of the lead screw 11 drives the scraper 12 to move backward and reset. The backward movement and reset of the scraper 12 contact the protection plate 15 and squeeze the protection plate 15. The protection plate 15 is squeezed by the scraper 12 and moves and resets in the direction close to the support frame 2. The movement of the protection plate 15 in the direction close to the support frame 2 aligns the protection hole 16 with the switch 17. The alignment of the protection hole 16 and the switch 17 enables the protection plate 15 to release the limit on the switch 17. After the limit of the switch 17 is released, manually press the switch 17 to drive the output end of the hydraulic device 3 to move downward. The downward movement of the output end of the hydraulic device 3 drives the connecting plate 4 to move downward. The downward movement of the connecting plate 4 drives the upper mold 5 to move downward. The downward movement of the upper mold 5 contacts the lower mold 9 and completes the mold closing. After the upper mold 5 contacts the lower mold 9 and completes the mold closing, start the externally connected injection mechanism to inject the molten plastic into the space between the upper mold 5 and the lower mold 9 through the injection pipe 191 for injection molding operations.

[0043] Please refer toFigures 1-7 , on the basis of the above embodiments, in another embodiment of the present invention, a dredging assembly for preventing the injection molding pipe 191 from being blocked is provided on the right side of the lower mold 9, and a demolding assembly is provided on the right side of the lower mold 9. The dredging assembly includes a connecting pipe 192, a pressing frame 193, a gear 194, an elastic telescopic rod 195 and a connecting groove 196. The connecting pipe 192 is slidably installed on the inner wall of the injection molding pipe 191. The pressing frame 193 rotatably penetrates the inner and outer walls of the injection molding pipe 191. The gear 194 is fixedly installed on the circumferential surface of the pressing frame 193. The elastic telescopic rod 195 is fixedly installed on the circumferential surface of the injection molding pipe 191. The connecting groove 196 is opened on the circumferential surface of the connecting pipe 192. By rotating the pressing frame 193, the accumulation of solidified plastic can be effectively broken, the pipeline can be kept unobstructed, so as to avoid blockage and ensure the smooth progress of the injection molding process.

[0044] A protective groove 197 is opened at the free end of the elastic telescopic rod 195. A protective plate 198 is slidably installed on the circumferential surface of the injection molding pipe 191. A second spring is provided between the protective plate 198 and the injection molding pipe 191. When the protective plate 198 moves upward, the second spring is compressed. The second spring deforms and stores energy under the extrusion of the protective plate 198. After manually releasing the protective plate 198, the protective plate 198 can be driven to reset by the second spring. A linkage rod 199 is fixedly installed on the circumferential surface of the pressing frame 193. The front side of the linkage rod 199 is arc-shaped. Through the fixing action of the protective plate 198, it can be ensured that the connection between the injection molding pipe 191 and the external injection molding mechanism is not loose, thereby reducing the risk of leakage and further ensuring the quality of the injection molded parts.

[0045] The free end of the elastic telescopic rod 195 is in contact with the inner wall of the connecting groove 196. A first fluororubber seal ring is provided between the connecting pipe 192 and the injection molding pipe 191. The first fluororubber seal ring can increase the sealing performance between the connecting pipe 192 and the injection molding pipe 191. A second fluororubber seal ring is provided between the pressing frame 193 and the injection molding pipe 191. The second fluororubber seal ring can increase the sealing performance between the pressing frame 193 and the injection molding pipe 191. The pressing frame 193 is in contact with the inner wall of the injection molding pipe 191.

[0046] The demolding assembly includes a demolding rod 201, a demolding frame 202, a return spring 203, a demolding disc 204, and a semi-circular block 205. The demolding rod 201 is fixedly installed on the right side of the lower mold 9. The demolding frame 202 is slidably installed on the circumferential surface of the demolding rod 201. The return spring 203 is arranged between the demolding frame 202 and the lower mold 9. When the demolding frame 202 moves away from the demolding disc 204, the return spring 203 is compressed. The return spring 203 deforms and stores energy under the extrusion of the demolding frame 202. After the linkage rod 199 disengages from the contact with the demolding frame 202, the return spring 203 can drive the demolding frame 202 to reset. The demolding disc 204 is fixedly installed on the right side of the demolding rod 201, and the semi-circular block 205 is fixedly installed on the left side of the demolding disc 204. The extrusion of the demolding frame 202 can effectively help the product to be demolded smoothly, reduce the occurrence of jamming, and thus avoid production stagnation caused by jamming.

[0047] The demolding frame 202 contacts the semi-circular block 205. The demolding frame 202 penetrates through the right side of the lower mold 9. A No. 3 fluororubber sealing ring is arranged between the demolding frame 202 and the lower mold 9. The sealing performance between the demolding frame 202 and the lower mold 9 can be increased through the No. 3 fluororubber sealing ring. The right side of the demolding frame 202 is set as an inclined surface. The frictional force between the linkage rod 199 and the demolding frame 202 can be reduced through the inclined surface of the demolding frame 202. Through the impact force and resonance effect generated by vibration, the demolding process can be further accelerated, thereby improving the stability of the product demolding process.

[0048] When this embodiment works: The scraper 12 moves forward to drive the rack 18 to move forward. The rack 18 moves forward to contact the gear 194 and extrude the gear 194. The gear 194 rotates under the extrusion of the rack 18. The rotation of the gear 194 drives the extrusion frame 193 to rotate. The extrusion frame 193 rotates to stir the solidified plastic inside the injection pipe 191. And when the injection pipe 191 is docked with the external injection mechanism, first manually push the protection plate 198 upward. The protection plate 198 moves upward to disengage from the contact with the protection groove 197 and release the limit on the free end of the elastic telescopic rod 195. After the limit on the free end of the elastic telescopic rod 195 is released, manually push the free end of the elastic telescopic rod 195 to move to the right. The free end of the elastic telescopic rod 195 moves to the right to disengage from the contact with the connection groove 196 and release the limit on the connecting pipe 192. After the limit on the connecting pipe 192 is released, manually push the connecting pipe 192 to move vertically to be docked with the external injection mechanism. After the connecting pipe 192 is docked with the external injection mechanism, release the free end of the elastic telescopic rod 195 so that the free end of the elastic telescopic rod 195 moves to the left to reset under the action of its own elastic force. The free end of the elastic telescopic rod 195 moves to the left to reset and contacts the inner wall of the connection groove 196 to restore the limit on the connecting pipe 192.

[0049] The rotation of the extrusion frame 193 drives the linkage rod 199 to rotate. The rotation of the linkage rod 199 contacts the inclined surface of the demolding frame 202 and extrudes the demolding frame 202. The demolding frame 202 moves away from the demolding tray 204 under the extrusion of the linkage rod 199. The movement of the demolding frame 202 away from the demolding tray 204 extrudes and pushes the stuck product. When the linkage rod 199 continues to rotate and disengages from the contact with the demolding frame 202, the disengagement of the linkage rod 199 from the demolding frame 202 causes the demolding frame 202 to move to the right and reset under the elastic force of the return spring 203. The movement of the demolding frame 202 to the right and reset impacts the semi-circular block 205 to generate vibration. The vibration of the demolding frame 202 drives the lower mold 9 to resonate together.

[0050] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
