Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to an anti-stick injection mold. Background Technology

[0002] Frame-type injection molded products typically have multiple through holes on their sides to save material. In mold design, slides are usually used to form the through holes. However, the large number of through holes and the thinness of the product make it easy for the product to stick to the slides. This causes the slides to easily deform the product during operation, affecting the molding quality and reducing the yield. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes an anti-stick injection mold that can improve the smoothness of product ejection and enhance molding quality.

[0004] According to a first aspect of the present invention, an anti-stick injection mold includes a molding mechanism, a guiding mechanism, and a delay mechanism. The molding mechanism includes a front mold core, a rear mold core, and multiple slide components. Each slide component includes a slide seat, an insert, and an ejector block. The insert is fixedly connected to the slide seat, and the ejector block is slidably connected to the insert. The front mold core, the rear mold core, the insert, and the ejector block form a mold cavity for molding a product. The guiding mechanism includes a shovel base and an inclined guide post. The shovel base is connected to the front mold core... The inclined guide post is fixedly connected to the shovel base and passes through the sliding seat. The shovel base has a flat surface. The delay mechanism includes a connecting rod, a sliding rod, and an elastic element. The connecting rod is fixedly connected to the top block and slidably connected to the insert. The sliding rod is slidably connected to the sliding seat. The two ends of the sliding rod abut against the connecting rod and the flat surface, respectively. The two ends of the elastic element abut against the insert and the sliding rod, respectively, to drive the connecting rod to abut against the sliding rod.

[0005] According to the embodiments of the present invention, the anti-stick injection mold has at least the following beneficial effects: the insert is fixedly connected to the slide seat, the top block is slidably connected to the insert, and the front mold core, rear mold core, insert, and top block form a mold cavity so that the product can be formed in the mold cavity. The shovel base is fixedly connected to the front mold core, the inclined guide post is fixedly connected to the shovel base and passes through the slide seat, the top block is fixedly connected to the connecting rod, the connecting rod is slidably connected to the insert, the slide rod passes through the slide seat and can slide on the slide seat, one end of the slide rod abuts against the connecting rod, and the other end abuts against the plane, and both ends of the elastic member abut against the insert and the slide rod respectively. When the front mold core separates from the rear mold core, the shovel base and the inclined guide pillar move synchronously with the front mold core. This allows the inclined guide pillar to drive the slide seat and insert away from the rear mold core, and the slide rod can slide on the plane to maintain a stable position. This allows the elastic element to drive the ejector block to press the product, preventing the product from sticking to the insert during its movement. Then, the slide rod separates from the plane, allowing the elastic element to drive the slide rod back to the slide seat, and the connecting rod can separate from the slide rod. This allows the insert to drive the ejector block away from the rear mold core, facilitating the product's exit from the mold cavity. The delay mechanism ensures that the product is pressed down by the ejector block during demolding, preventing it from sticking to the insert, reducing the possibility of product deformation, and improving the yield rate.

[0006] According to some embodiments of the present invention, the delay mechanism further includes a sliding sleeve, which is sleeved in the connecting rod, and the sliding sleeve is slidably connected to the insert.

[0007] According to some embodiments of the present invention, a guide portion is provided at the end of the slide rod near the plane, and the guide portion is hemispherical in shape.

[0008] According to some embodiments of the present invention, the molding mechanism further includes a first connecting plate, the front mold core and the shovel base are both fixedly connected to the first connecting plate, and the sliding seat is fixedly connected to a first wear-resistant plate, which can abut against the shovel base.

[0009] According to some embodiments of the present invention, the guiding mechanism further includes a backhoe, which is fixedly connected to the first connecting plate and can abut against the row seat.

[0010] According to some embodiments of the present invention, the backhoe is fixedly connected to a second wear-resistant plate, which can abut against the row seat.

[0012] According to some embodiments of the present invention, the forming mechanism further includes two guide blocks, both of which are fixedly connected to the second connecting plate, and the row seat is slidably connected between the two guide blocks.

[0013] According to some embodiments of the present invention, the guiding mechanism further includes an ejection assembly, which includes a movable plate and multiple ejector rods, all of which are fixedly connected to the movable plate and can extend into the mold cavity.

[0014] According to some embodiments of the present invention, the front mold core, the rear mold core, the slide seat, and the insert are all provided with multiple cooling water channels, which are used to introduce cooling water.

[0015] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0034] Understandably, referring to Figures 1 to 5The present invention relates to an anti-stick injection mold, comprising a molding mechanism 100, a guiding mechanism 200, and a delay mechanism 300. The molding mechanism 100 includes a front mold core 110, a rear mold core 120, and multiple sliding components 130. Each sliding component 130 includes a sliding seat 131, an insert 132, and an ejector block 133. The insert 132 is fixedly connected to the sliding seat 131, and the ejector block 133 is slidably connected to the insert 132. The front mold core 110, rear mold core 120, insert 132, and ejector block 133 form a mold cavity 140, which is used to mold products. The guiding mechanism 200 includes a spade base 210 and an inclined guide post 220. The spade base 210 is connected to the front mold core 200. The core 110 is fixedly connected, the inclined guide post 220 is fixedly connected to the shovel base 210, and the inclined guide post 220 passes through the sliding seat 131. The shovel base 210 is provided with a plane 211. The delay mechanism 300 includes a connecting rod 310, a sliding rod 320 and an elastic element 330. The connecting rod 310 is fixedly connected to the top block 133 and is slidably connected to the insert 132. The sliding rod 320 is slidably connected to the sliding seat 131. The two ends of the sliding rod 320 abut against the connecting rod 310 and the plane 211 respectively. The two ends of the elastic element 330 can abut against the insert 132 and the sliding rod 320 respectively, so as to drive the connecting rod 310 to abut against the sliding rod 320.

[0035] Insert 132 is fixedly connected to slide seat 131, and top block 133 is slidably connected to insert 132. Front mold core 110, rear mold core 120, insert 132, and top block 133 form mold cavity 140 so that the product can be formed in mold cavity 140. Shovel base 210 is fixedly connected to front mold core 110, inclined guide post 220 is fixedly connected to shovel base 210 and passes through slide seat 131, top block 133 is fixedly connected to connecting rod 310, connecting rod 310 is slidably connected to insert 132, slide rod 320 passes through slide seat 131 and can slide on slide seat 131, one end of slide rod 320 abuts against connecting rod 310, and the other end abuts against plane 211, and both ends of elastic member 330 abut against insert 132 and slide rod 320 respectively. When the front mold core 110 separates from the rear mold core 120, the shovel base 210 and the inclined guide post 220 move synchronously with the front mold core 110, so that the inclined guide post 220 can drive the slide seat 131 and the insert 132 to move away from the rear mold core 120, and the slide rod 320 can slide on the plane 211, so that the position of the slide rod 320 remains stable when the slide seat 131 slides, thereby enabling the elastic element 330 to drive the top block 133 to press the product, preventing the product from sticking to the insert 132 when it moves. Then the slide rod 320 separates from the plane 211, so that the elastic element 330 can drive the slide rod 320 to retract into the slide seat 131, and the connecting rod 310 can separate from the slide rod 320, thereby enabling the insert 132 to drive the top block 133 to move away from the rear mold core 120, so that the product can be output from the mold cavity 140. The delay mechanism 300 can ensure that the product is pressed down by the top block 133 when it is ejected from the mold, thus preventing the product from sticking to the insert 132, reducing the possibility of product deformation, and improving the yield rate.

[0036] Raw material is injected into the mold cavity 140 so that the product can be formed within the mold cavity 140. Then, the front mold core 110 and the shovel base 210 are driven to rise so that the inclined guide post 220 can drive the slide seat 131 to move away from the rear mold core 120, and the slide rod 320 can slide on the plane 211 to maintain the position of the slide rod 320. This allows the ejector block 133 to press the product onto the rear mold core 120 when the slide seat 131 drives the insert 132 to separate from the product, thereby preventing the product from sticking to the insert 132 and reducing the possibility of the product being stretched and deformed. Then, the slide rod 320 separates from the plane 211, and the inclined guide post 220 drives the slide seat 131 to continue to move backward, allowing the slide rod 320 to slide on the slide seat 131, and allowing the insert 132 to drive the ejector block 133 to move backward through the connecting rod 310, thus realizing the automatic demolding of the product. By setting the delay mechanism 300, the insert 132 and the top block 133 can be separated from the product in sequence, which can gradually reduce the contact area with the product, reduce the possibility of the product sticking to the insert 132 or the top block 133, improve the demolding stability of the product, and improve the yield.

[0037] Among them, reference Figure 8 The product has multiple through holes 410 on its side wall. The insert 132 corresponds to the through holes 410 on the side wall so that when the insert 132 is separated from the product, the top block 133 can press down on the side wall of the product, preventing the side wall of the through hole 410 from sticking to the insert 132, thereby making the product demold smoothly, reducing the possibility of product deformation, and improving the yield.

[0038] It should be noted that the front mold core 110 and the shovel base 210 can be driven by the drive element on the injection molding machine so that the front mold core 110 and the shovel base 210 can move synchronously. The drive element can be a linear cylinder, an electric actuator, a linear slide module, etc., which are not limited here.

[0039] Alternatively, the connecting rod 310 can be a bolt, and the connecting rod 310 is threaded to the top block 133 so that the top block 133 can move axially along the connecting rod 310. When the insert 132 retracts, the end of the connecting rod 310 can abut against the insert 132, so that the insert 132 can drive the top block 133 to retract.

[0040] Understandably, referring to Figure 3 , Figure 5 and Figure 6 The delay mechanism 300 also includes a sliding sleeve 340, which is fitted within the connecting rod 310 and slidably connected to the insert 132. The sliding sleeve 340 separates the connecting rod 310 and the insert 132, reducing wear caused by direct contact and minimizing wobbling of the connecting rod 310 during sliding. This results in a smoother and more controllable pressing action of the top block 133 on the product. Furthermore, the sliding sleeve 340 facilitates easy assembly and disassembly of the connecting rod 310, reducing maintenance difficulty, extending service life, and improving the reliability of the delay mechanism 300.

[0041] Understandably, referring to Figure 5 and Figure 6 A guide portion 321 is provided at the end of the slide rod 320 near the plane 211. The guide portion 321 is hemispherical in shape. The guide portion 321 is arranged at the end of the slide rod 320 near the plane 211 and can slide on the plane 211. By setting the shape of the guide portion 321 to hemispherical, the contact between the slide rod 320 and the plane 211 is smoother, the contact area between the slide rod 320 and the plane 211 is reduced, the frictional resistance is reduced, and thus the service life of the mold is extended.

[0042] In addition, the hemispherical guide part 321 can make the sliding rod 320 contact or separate from the shovel base 210 more smoothly, make the movement trajectory of the mold accurate during the opening and closing process, enhance the opening and closing stability of the mold, prevent the shovel base 210 from colliding and being damaged by the sliding rod 320, and improve reliability.

[0043] Understandably, referring to Figure 5 and Figure 6 The molding mechanism 100 also includes a first connecting plate 150. The front mold core 110 and the shovel base 210 are both fixedly connected to the first connecting plate 150. The sliding seat 131 is fixedly connected to a first wear-resistant plate 134, which can abut against the shovel base 210. The front mold core 110 and the shovel base 210 are both fixedly connected to the first connecting plate 150. By driving the first connecting plate 150 to move, the front mold core 110 and the shovel base 210 can move synchronously, improving the stability of the movement.

[0044] The first wear-resistant plate 134 is fixedly connected to the slide seat 131, and the first wear-resistant plate 134 is arranged between the slide seat 131 and the shovel base 210. By setting the first wear-resistant plate 134, the slide seat 131 and the shovel base 210 can be separated, which effectively reduces the direct friction between the slide seat 131 and the shovel base 210, reduces the deformation or damage caused by long-term friction between the slide seat 131 and the shovel base 210, and extends the service life of the mold.

[0045] In addition, by setting the first wear-resistant plate 134, the distance between the slide seat 131 and the shovel base 210 can be easily adjusted, so that the slide seat 131 and the shovel base 210 are tightly connected, reducing the positional wobbling of the slide seat 131 and helping to improve the molding accuracy of the product.

[0046] It should be noted that the first wear-resistant plate 134 can be detachably connected to the slide seat 131 by fasteners, which can facilitate the disassembly and assembly of the first wear-resistant plate 134, improve the convenience of maintenance, and extend the service life of the anti-stick slide injection mold.

[0047] Specifically, refer to Figure 2 and Figure 7 The guiding mechanism 200 also includes a backhoe 230, which is fixedly connected to the first connecting plate 150 and can abut against the slide seat 131. The backhoe 230 is fixedly connected to the first connecting plate 150, and by setting the first connecting plate 150 to abut against the slide seat 131, the horizontal movement of the slide seat 131 is restricted. This allows the molding pressure of the product in the mold cavity 140 to be transmitted to the backhoe 230 through the slide seat 131, thereby preventing the slide seat 131 from shifting or shaking during product molding, which helps improve the molding accuracy and yield of the product.

[0048] Specifically, refer to Figure 2 and Figure 7 The backhoe 230 is fixedly connected to a second wear-resistant plate 231, which can abut against the slide seat 131. The second wear-resistant plate 231 is fixedly connected to the backhoe 230, and can separate the backhoe 230 and the slide seat 131 so that when the mold opens and closes, the wear caused by the contact between the slide seat 131 and the backhoe 230 can be absorbed by the second wear-resistant plate 231, thereby extending the service life of the backhoe 230 and the slide seat 131 and reducing the maintenance cost of the mold.

[0049] It should be noted that the second wear-resistant plate 231 can be detachably connected to the backhoe 230 via fasteners, which facilitates the disassembly and assembly of the second wear-resistant plate 231, improves the convenience of maintenance, and extends the service life of the anti-stick injection mold.

[0050] Understandably, referring to Figure 2 and Figure 7 The molding mechanism 100 also includes a second connecting plate 160, to which the rear mold core 120 is fixedly connected. A third wear-resistant plate 161 is fixedly connected to the second connecting plate 160, and the third wear-resistant plate 161 can abut against the slide seat 131. By providing the third wear-resistant plate 161, the second connecting plate 160 and the slide seat 131 are separated, reducing direct friction between the slide seat 131 and the second connecting plate 160, lowering the possibility of mutual wear and damage between the slide seat 131 and the second connecting plate 160, and extending the service life of the mold.

[0051] It should be noted that the third wear-resistant plate 161 can be detachably connected to the second connecting plate 160 by fasteners, which facilitates the disassembly and assembly of the third wear-resistant plate 161, improves the convenience of maintenance, and extends the service life of the anti-stick injection mold.

[0052] Specifically, refer to Figure 2 and Figure 3 The molding mechanism 100 also includes two guide blocks 170, both of which are fixedly connected to the second connecting plate 160. A sliding seat 131 is slidably connected between the two guide blocks 170. The two guide blocks 170 are fixedly connected to the second connecting plate 160 and are arranged at intervals. The sliding seat 131 is slidably connected between the two guide blocks 170 to limit the movement direction of the sliding seat 131, ensuring stable and accurate movement, reducing positional deviation, enhancing the stability and reliability of the mold structure, improving product molding quality, and increasing yield.

[0053] Understandably, referring to Figure 7The guiding mechanism 200 also includes an ejection assembly 240, which includes a movable plate 241 and multiple ejector rods 242. The ejector rods 242 are all fixedly connected to the movable plate 241 and can extend into the mold cavity 140. By driving the multiple ejector rods 242 to move synchronously through the movable plate 241, the ejector rods 242 can extend into the mold cavity 140, allowing the product to be ejected from the mold cavity 140 evenly and quickly after cooling and solidification. This reduces product deformation or damage, replaces manual material handling, and improves production efficiency.

[0054] In addition, the multiple ejector pins 242 are arranged at intervals, which makes the product stable under force, facilitates product demolding, and improves efficiency.

[0055] It should be noted that the movable plate 241 can be driven by the drive components on the injection molding machine to achieve automatic product ejection and improve production efficiency.

[0056] Understandably, referring to Figure 1 and Figure 4 The front mold core 110, rear mold core 120, slide seat 131, and insert 132 are all provided with multiple cooling water channels 180 for introducing cooling water. These cooling water channels 180 are arranged adjacent to the mold cavity 140, allowing cooling water to flow into them. This ensures that the cooling water can more evenly remove the heat generated during injection molding, accelerating the cooling and solidification process of the product in the mold cavity 140, shortening the production cycle, and improving production efficiency.

[0057] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
