Technical Field

[0001] This utility model relates to the field of injection mold technology, and in particular to a rapid demolding and separation mechanism for plastic after injection molding. Background Technology

[0002] Plastics are a class of malleable polymer materials, also known as plastics. They are typically composed of synthetic resins and additives such as fillers, plasticizers, stabilizers, lubricants, and colorants. Plastics have excellent processing properties and can be manufactured into products of various shapes and sizes through injection molding, extrusion, blow molding, and other processes. They are widely used in many fields, including daily life and industrial production. Examples include common plastic bags, plastic bottles, and appliance casings.

[0003] In existing technology, when demolding plastic products, injection molds need to first move the moving mold to one side to separate it from the fixed mold, and then push the plastic product out of the fixed mold through the ejector pin to complete the demolding operation. This process requires waiting for a certain amount of time, resulting in low demolding efficiency of plastic products. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the prior art where, when demolding plastic products, the moving mold needs to be moved to one side to separate from the fixed mold, and then the plastic product is pushed out of the fixed mold by a push rod to complete the demolding operation. This process requires waiting for a certain amount of time, resulting in low demolding efficiency.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a rapid demolding and separation mechanism for injection-molded plastic, comprising: a moving mold and a fixed mold, wherein the fixed mold is disposed on one side of the moving mold, and further comprising:

A movable plate is slidably connected inside the fixed mold. An L-shaped rack is fixedly connected to each of the four corners of one side of the movable plate. Two round rods are symmetrically fixedly connected to opposite sides of the fixed mold. Gears are rotatably connected to the outer surface of the round rods, and the gears mesh with the L-shaped racks and the straight racks. Two square slots are symmetrically formed on one side of the movable plate. A movable strip is rotatably connected to the inner wall of the square slot through a support rod. A fixed rod is fixedly connected to the opposite side of the inner wall of the fixed mold. Two movable strips are symmetrically rotatably connected to the outer surface of the fixed rod. Movable strips are rotatably connected to movable strips 1 through a support rod. A movable plate is slidably connected inside the fixed mold. Two square slots are symmetrically formed on one side of the movable plate. Movable strips are rotatably connected to the inner wall of the square slots 2 through a support rod. Movable strips are rotatably connected to movable strips 2 through a support rod. Multiple push rods are fixedly connected to one side of the movable plate.

[0007] Preferably, a plurality of injection grooves are provided on one side of the fixed mold, a circular groove is provided on one side of the inner wall of the injection groove, the outer surface of the push rod is slidably connected to the inside of the circular groove, and a cylinder is fixedly connected to one side of the moving mold.

[0008] Preferably, two sliders are symmetrically fixedly connected to opposite sides of the fixed mold, and a groove is provided on one side of the L-shaped rack, with the outer surface of the slider slidably connected to the inside of the groove.

[0009] Preferably, the bottom of the fixed mold is symmetrically fixedly connected to two fixed blocks, one side of each fixed block is rotatably connected to a rotating rod, and one end of each rotating rod is fixedly connected to a receiving frame.

[0010] Preferably, a fixing strip 2 is fixedly connected to the opposite side of the fixed mold near the bottom, a guide rod is slidably connected to the top of the fixing strip 2, an L-shaped strip is fixedly connected to one end of the guide rod, and a sliding groove 2 is opened on the side of the L-shaped strip near the top.

[0011] Preferably, a fixing strip is fixedly connected to one side of the gear, and a sliding rod is fixedly connected to one side of the fixing strip. The outer surface of the sliding rod is slidably connected to the inside of the sliding groove.

[0012] Preferably, one end of the rotating rod is fixedly connected to a square bar, and a sliding groove is provided on one side of the square bar.

[0013] Preferably, a second slide rod is fixedly connected to the side of the L-shaped strip near the bottom, and the outer surface of the second slide rod is slidably connected to the inside of the third slide groove.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] 1. This utility model uses a controller to control the cylinder to retract, causing it to move the moving mold to one side, simultaneously moving the connecting plate and the rack to one side. Then, with the rack and gear meshing, the gear rotates. Next, with the gear and L-shaped rack meshing, the L-shaped rack moves to the other side, simultaneously moving the first movable plate to the other side. A pulling force is applied to the first movable plate, causing it to rotate at an appropriate angle via the support rod. A pulling force is also applied to the second movable plate, causing it to rotate around the fixed rod. By rotating the movable strip at an appropriate angle, a pushing force is applied to the movable strip three, causing it to rotate at an appropriate angle via the support rod. This also applies a pushing force to the movable plate two, causing it to slide towards the moving mold side. Simultaneously, the push rod slides into the injection mold along the inside of the circular groove, ejecting the cooled plastic product. At this point, there is a certain distance between the moving mold and the fixed mold, allowing the plastic product to fall directly. This completes the separation operation of the moving mold and the fixed mold, and simultaneously completes the demolding operation of the plastic product, reducing waiting time and thus improving the demolding efficiency of the plastic product.

[0016] 2. This utility model, through the rotation of gears, drives the first fixed strip and the first sliding rod to rotate, causing the first sliding rod to apply downward pressure to the L-shaped strip, causing the guide rod to slide downward along the inside of the second fixed strip. Simultaneously, the first sliding rod slides inside the second sliding groove, causing the L-shaped strip and the second sliding rod to move downward, allowing the second sliding rod to slide an appropriate distance inside the third sliding groove, and applying a force to the square strip, causing the square strip to rotate downward. With the cooperation of the rotating rod, the receiving frame rotates upward. When the receiving frame rotates to the horizontal position, the plastic product is just demolded and falls into the receiving frame. Then, the controller controls the cylinder to extend, which can merge the moving mold and the fixed mold together, reset the other structural components, and cause the receiving frame to gradually rotate downward and return to the initial state, allowing the plastic product inside the receiving frame to slide downward. A collection frame can be set below to collect the plastic product, which can prevent the plastic product from falling from a height into the collection frame and being damaged due to collision, thereby improving the quality of the plastic product.

L-shaped racks 202 are fixedly connected to the four corners of one side of the movable plate 201. Two round rods 205 are symmetrically fixedly connected to opposite sides of the fixed mold 2. Gears 206 are rotatably connected to the outer surface of the round rods 205. The gears 206 mesh with the L-shaped racks 202 and the straight racks 102. The movable plate 201... Two square grooves 207 are symmetrically formed. The inner wall of square groove 207 is rotatably connected to movable strip 208 via support rods. A fixed rod 209 is fixedly connected to the opposite side of the inner wall of the fixed mold 2. Two movable strips 210 are symmetrically rotatably connected to the outer surface of the fixed rod 209. Movable strips 210 and movable strip 208 are rotatably connected via support rods. Movable plate 212 is slidably connected inside the fixed mold 2. Two square grooves 213 are symmetrically formed on one side of movable plate 212. Movable strip 211 is rotatably connected to the inner wall of square groove 213 via support rods. Movable strip 211 and movable strip 210 are rotatably connected via support rods. Multiple push rods 216 are fixedly connected to one side of movable plate 212.

[0026] Furthermore, such as Figure 1-4 As shown, a plurality of injection grooves 214 are provided on one side of the fixed mold 2, and a circular groove 215 is provided on one side of the inner wall of the injection groove 214. The outer surface of the push rod 216 is slidably connected to the inside of the circular groove 215. A cylinder 103 is fixedly connected to one side of the moving mold 1. With the above arrangement, the push rod 216 can slide into the injection groove 214 along the inside of the circular groove 215 to push out the plastic product and complete the demolding operation.

[0027] Furthermore, such as Figure 1-4 As shown, two sliders 204 are symmetrically fixedly connected to opposite sides of the fixed mold 2. A groove 203 is provided on one side of the L-shaped rack 202. The outer surface of the slider 204 is slidably connected to the inside of the groove 203. Through the cooperation of the groove 203 and the slider 204, the L-shaped rack 202 is supported and guided.

[0028] Furthermore, such as Figure 1-4 As shown, two fixing blocks 307 are symmetrically fixedly connected to the bottom of the fixed mold 2. A rotating rod 308 is rotatably connected to one side of the fixing block 307. A receiving frame 309 is fixedly connected to one end of the two rotating rods 308. With the above settings, the receiving frame 309 can be rotated up or down at an appropriate angle.

[0029] Furthermore, such as Figure 1-4As shown, fixed strips 305 are fixedly connected to the opposite side of the fixed mold 2 near the bottom. A guide rod 304 is slidably connected to the top of the fixed strip 305. An L-shaped strip 302 is fixedly connected to one end of the guide rod 304. A groove 303 is provided on the side of the L-shaped strip 302 near the top. With the above arrangement, the guide rod 304 can slide up and down along the inside of the fixed strip 305, which plays the role of guiding the L-shaped strip 302.

[0030] Furthermore, such as Figure 1-4 As shown, a fixing strip 3 is fixedly connected to one side of the gear 206, and a sliding rod 301 is fixedly connected to one side of the fixing strip 3. The outer surface of the sliding rod 301 is slidably connected to the inside of the sliding groove 303. With the above arrangement, when the gear 206 rotates, it can drive the fixing strip 3 and the sliding rod 301 to rotate, so that the sliding rod 301 slides inside the sliding groove 303 and applies a force to the L-shaped strip 302.

[0031] Furthermore, such as Figure 1-4 As shown, a square bar 310 is fixedly connected to one end of the rotating rod 308. A sliding groove 311 is provided on one side of the square bar 310. With the above-mentioned arrangement, when the square bar 310 is subjected to force, it can rotate upward or downward at an appropriate angle, and simultaneously drive the rotating rod 308 to rotate.

[0032] Furthermore, such as Figure 1-4 As shown, a slide rod 306 is fixedly connected to the side of the L-shaped strip 302 near the bottom. The outer surface of the slide rod 306 is slidably connected to the inside of the groove 311. With the above arrangement, when the slide rod 306 moves down or up, it can slide inside the groove 311 and apply a force to the square strip 310.

[0033] Working principle: During use, cylinder 103 is fixed to the housing of the injection molding equipment. When demolding is required, the controller controls cylinder 103 to retract, causing it to move the moving mold 1 to one side. Simultaneously, this moves connecting plate 101 and rack 102 to one side. Then, with the meshing of rack 102 and gear 206, gear 206 can rotate. Then, with the meshing of gear 206 and L-shaped rack 202, L-shaped rack 202 can move to the other side, simultaneously moving movable plate 201 to the other side. This applies a pulling force to movable bar 208, causing movable bar 208 to rotate via the support rod. At an appropriate angle, a pulling force is applied to movable strip 210, causing it to rotate around fixed rod 209 by an appropriate angle. A pushing force is applied to movable strip 211, causing it to rotate through support rod by an appropriate angle. A pushing force is also applied to movable plate 212, causing it to slide towards moving mold 1. Simultaneously, push rod 216 slides along the inside of circular groove 215 into injection mold 214, ejecting the cooled plastic product. At this point, there is a certain distance between moving mold 1 and fixed mold 2, allowing the plastic product to fall directly. This completes the separation operation of moving mold 1 and fixed mold 2, and simultaneously completes the separation of the plastic product. The demolding operation reduces waiting time, thereby improving the efficiency of demolding plastic products. Simultaneously, the rotation of gear 206 drives the fixed strip 3 and slide rod 301 to rotate, causing slide rod 301 to apply downward pressure to the L-shaped strip 302. This causes guide rod 304 to slide downwards along the interior of fixed strip 305, simultaneously causing slide rod 301 to slide within slide groove 303. This moves the L-shaped strip 302 and slide rod 306 downwards, allowing slide rod 306 to slide an appropriate distance within slide groove 311. A force is also applied to square strip 310, causing it to rotate downwards. With the cooperation of rotating rod 308... The receiving frame 309 is rotated upwards. When the receiving frame 309 rotates to the horizontal position, the plastic product is just demolded and falls into the receiving frame 309. Then, the controller controls the cylinder 103 to extend, which can merge the moving mold 1 and the fixed mold 2 together and reset the other structural components. The receiving frame 309 is then gradually rotated downwards and returned to its initial state, allowing the plastic product inside the receiving frame 309 to slide down. A collection box can be set below to collect the plastic product, which can prevent the plastic product from falling from a height into the collection box and being damaged due to collision, thereby improving the quality of the plastic product.

[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
