Description

Technical Field

[0001] The invention relates to the technical field of injection molds, in particular to a battery slot injection mold and an edge burr waste processing and recycling device. Background Art

[0002] As the global demand for renewable energy and electric vehicles continues to increase, the production and application of various types of batteries are becoming increasingly important. In particular, the widespread use of lithium batteries and nickel-metal hydride batteries in electric vehicles and energy storage systems has made the production process, mold design and waste treatment level of corresponding battery accessories, such as battery tanks, a key to the development of the industry.

[0003] Existing battery slot injection molds mainly use traditional processing technologies, which have achieved efficient production of battery slots to some extent, but there are still some problems:

[0004] First, during the demolding process, most of the existing injection molds use a single-sided ejector to eject the molded battery slot from the punch. However, the ejector on one side may cause uneven ejection force when ejecting the molded part, which may easily generate excessive pressure on one side of the molded part and insufficient pressure on the other side. This uneven ejection force may cause the molded part to deform, damage, or even break or crack during the demolding process. In addition, the mold is prone to forming burrs at the connection between the injection port and the molding cavity, and there is a lack of a structure to deal with it in a timely manner. Therefore, additional post-processing steps are still required to remove the burrs after molding, which will increase the production process, extend the production cycle, and increase the investment cost of manpower and equipment.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The present invention can effectively reduce the contact area between the inner and outer sides of the injection molded part and the mold when the injection molded part is demolded by arranging an outer clamping strip and an inner clamping strip that can perform telescopic movement, thereby achieving the effect of reducing stress concentration and friction, and reducing the possibility of the molded part being stuck in the mold; and by promoting demolding through the cooperation of multiple matrix-distributed ejector rods and the outer pressure plate, the ejection force applied to the injection molded part can be effectively dispersed, reducing the risk of deformation or damage of the injection molded part, thereby ensuring smooth demolding of the injection molded part, reducing the demolding time, and improving production efficiency.

[0020] 2. The present invention cooperates with a No. 1 spring, a main push plate, a longitudinal push strip and a connecting frame. On the one hand, the outer clamping strip can extend outward when the fixed mold and the movable mold are in contact, thereby ensuring the integrity of the molding cavity; on the other hand, when the stripping module gradually separates from the sink, the outer clamping strip can quickly retract inward, thereby reducing the contact area between the injection molded part and the inner wall of the sink, which helps to reduce the friction of the injection molded part when the stripping module is separated from the fixed mold; and helps the stripping module to be smoothly pulled out of the sink.

[0021] 3. The present invention, through the coordinated use of a rotating wheel, a transverse rack, a transverse moving plate, a cylindrical pin and a cross moving plate, can convert the longitudinal driving force of the longitudinal push cylinder into a 90° forward and reverse rotational motion of two sets of pressure arms, so that the outer pressure plate can compress or loosen the injection molded part well, and the active push cylinder pushes the top plate to move horizontally, so that the outer pressure plate can maintain lateral pressure on the injection molded part while exerting force together with the ejector rod to push the injection molded part out of the mold. This method of demolding by combining internal and external forces makes the demolding process more stable and less prone to failure or jamming, thereby ensuring the continuity of production.

[0022] 4. By setting a lateral push rod, a push strip, a push slide and a cross plate, the inner clamping strip can adaptively extend and retract according to the movement state of the ejector rod. When the ejector rod retracts inward, the inner clamping strip extends outward to ensure the integrity of the surface of the stripping module; when the ejector rod extends outward, the inner clamping strip retracts inward immediately, thereby reducing the contact area between the injection molded part and the side wall of the stripping module, which helps to reduce the friction when the injection molded part is separated from the stripping module; and helps the injection molded part to be smoothly pulled out from the stripping module.

[0023] 5. Through the design of fixed rack, spur gear, movable tooth plate, No. 3 spring and driven push column, the downward pushing force of the transition push column can be converted into the linear up and down movement of the recovery bin, so that the outer pressure plate can convey the demoulded battery slot downward while the grinding wheel can move upward with the recovery bin, so as to cut and grind the burrs on the battery slot, and the waste after cutting can fall into the recovery bin for centralized processing, thereby avoiding the secondary processing of the injection molded parts in subsequent operations and reducing labor and time costs.

[0040] See also Figures 1 to 14 The present invention provides a technical solution: a battery slot injection mold, comprising a fixed mold 1 and a movable mold 2, wherein an assembly seat 30 is provided at the lower end of the fixed mold 1, and the movable mold 2 is limitedly slidably installed on the assembly seat 30, and is horizontally pushed by a hydraulic cylinder to achieve the close contact or separation of the movable mold 2 and the fixed mold 1; a stripping module 8 is protrudingly provided on the side of the movable mold 2 close to the fixed mold 1, and a sink 101 for accommodating the stripping module 8 is provided on the fixed mold 1, and a molding cavity for accommodating the battery slot 42 is formed between the stripping module 8 and the sink 101, and an injection hole 102 is provided at one end of the sink 101 away from the fixed mold 1, and outer clips 7 are distributed around the side walls of the sink 101, and multiple groups of outer clips 7 are telescopically moved under the push of the first linkage component to reduce the friction force of the injection molded part from being demolded from the outside; the stripping module 8 Four interlocking columns 9 are arranged on the outer periphery, and the interlocking columns 9 are fixedly arranged on the side wall of the movable mold 2. A top plate 11 is slidably installed inside the movable mold 2. One end of the top plate 11 is driven by a pushing assembly, and the other end of the top plate 11 is fixedly provided with a plurality of ejector rods 10 that penetrate the demolding module 8, which are used to push the injection molded parts to be demolded from the inside; a group of hinged seats 26 are slidably installed on both horizontal sides of the movable mold 2, and a group of pressure arms 18 are rotatably installed on each group of hinged seats 26. The two groups of pressure arms 18 are driven by the driven assembly and perform a forward and reverse 90° deflection movement, which are used for external auxiliary pushing and demolding of the injection molded parts; inner clip strips 16 are distributed around the side walls of the demolding module 8, and multiple groups of outer clip strips 7 perform telescopic movement under the drive of the second linkage assembly, which are used to reduce the friction force of the injection molded parts from being demolded from the inside.

[0041] Furthermore, the present invention can effectively reduce the contact area between the inner and outer sides of the mold when the injection molded part is demolded by providing an outer clamping strip 7 and an inner clamping strip 16 that can perform telescopic movement, thereby achieving the effect of reducing stress concentration and friction, and reducing the possibility of the molded part getting stuck in the mold; and by promoting demolding through the cooperation of multiple matrix-distributed ejector rods 10 and the outer pressure plate 17, the ejection force applied to the injection molded part can be effectively dispersed, reducing the risk of deformation or damage of the injection molded part, thereby ensuring smooth demolding of the injection molded part, reducing demolding time, and improving production efficiency.

[0042] like Figure 2 , Figure 7 ,as well as Figure 8As shown, the side wall of the movable mold 2 is provided with an L-shaped slide groove for accommodating the sliding of the hinge seat 26, and the L-shaped slide groove is provided with a transition push column 27 for limiting sliding installation. A group of limit blocks 28 are fixedly connected to both sides of the upper end of the transition push column 27. The limit blocks 28 are limitedly slidably installed in the movable mold 2 and a No. 2 spring 29 is fixedly connected to the lower end thereof. The lower end of the transition push column 27 passes through the bottom wall of the movable mold 2 and contacts the connected assembly seat 30. The upper end wall of the assembly seat 30 is provided with a rectangular through hole for accommodating the transition push column 27.

[0043] Specifically, when the hinge seat 26 squeezes the transition push post 27 to move downward, the transition push post 27 moves downward and pushes the driven push post 41; when the hinge seat 26 moves upward, the transition push post 27 moves rapidly upward under the elastic force of the No. 2 spring 29.

[0044] like Figure 4-6 As shown, a matching cavity for accommodating a first linkage component is provided in the fixed mold 1, and the first linkage component includes a No. 1 spring 3, a main push plate 4, a longitudinal push strip 5 and a connecting frame 6. The outer clamping strip 7 is self-sinking in the groove 101 and extends into the inner side of the fixed mold 1 and is fixedly connected to the connecting frame 6. The connecting frame 6 and the main push plate 4 are both limitedly slidably installed in the fixed mold 1. A driving inclined groove 601 for accommodating the longitudinal push strip 5 is provided on the side wall of the connecting frame 6. One end of the longitudinal push strip 5 away from the driving inclined groove 601 is fixedly connected to the main push plate 4. A No. 1 spring 3 is fixedly provided on one side of the main push plate 4, and the other side of the main push plate 4 extends out of the fixed mold 1 and is connected to the outer wall of the movable mold 2.

[0045] Furthermore, the present invention cooperates with a No. 1 spring 3, a main push plate 4, a longitudinal push strip 5 and a connecting frame 6. On the one hand, the outer clamping strip 7 can extend outward when the fixed mold 1 abuts against the movable mold 2, thereby ensuring the integrity of the molding cavity; on the other hand, when the stripping module 8 gradually separates from the sink 101, the outer clamping strip 7 can quickly retract inward, thereby reducing the contact area between the injection molded part and the inner wall of the sink 101, which helps to reduce the friction on the injection molded part when the stripping module 8 is separated from the fixed mold 1; and helps to smoothly pull the stripping module 8 out of the sink 101.

[0046] like Figure 8 , Fig. 9 as well as Fig.11As shown, a cylindrical groove for accommodating the interlocking column 9 is provided on one side of the fixed mold 1 close to the movable mold 2, and a pushing assembly is arranged inside the movable mold 2, and the pushing assembly includes an active push cylinder 12, the end cover of which is fixedly arranged in the movable mold 2, and the piston rod of the active push cylinder 12 extends outward and is fixedly connected to the top plate 11, and a driven assembly is arranged inside the top plate 11. The driven assembly includes a transverse moving plate 21, a cylindrical pin 23, a cross moving plate 24 and a longitudinal push cylinder 25, the cross moving plate 24 is limitedly slidably installed in the top plate 11, the piston rod of the longitudinal push cylinder 25 extends downward and is fixedly connected to the top wall of the cross moving plate 24, and the horizontal ends of the cross moving plate 24 are fixedly connected with cylindrical pins 23. A lateral inclined groove 22 for accommodating a cylindrical pin 23 is provided at one end of the transverse moving plate 21, and the other end of the transverse moving plate 21 extends into the hinge seat 26 and is fixedly connected to a transverse rack 20. The transverse rack 20 is installed in the hinge seat 26 for limited sliding and is meshingly connected to the rotating wheel 19. One end of the pressure arm 18 is coaxially fixedly connected to the rotating wheel 19, and the other end of the pressure arm 18 is fixedly connected to an outer pressure plate 17.

[0047] Furthermore, by setting up a rotating wheel 19, a transverse rack 20, a transverse movable plate 21, a cylindrical pin 23 and a cross movable plate 24 for use in combination, the longitudinal driving force of the longitudinal push cylinder 25 can be converted into a 90° forward and reverse rotation movement of the two sets of pressure arms 18, so that the outer pressure plate 17 can be well pressed or loosened injection molded parts, and the active push cylinder 12 pushes the top plate 11 to move horizontally, so that the outer pressure plate 17 can maintain lateral pressure on the injection molded parts while also exerting force together with the ejector rod 10 to push the injection molded parts out of the mold. This method of demolding by combining internal and external forces makes the demolding process more stable and less prone to failure or jamming, thereby ensuring the continuity of production.

[0048] like Figure 8-Figure 10 As shown, the movable mold 2 is provided with a second linkage assembly connected to the ejector rod 10, and the second linkage assembly includes a lateral push rod 13 and a matching push strip 14, the matching push strip 14 is limitedly slidably installed in the movable mold 2, and a push slide 1401 is provided through the matching push strip 14, and the push slide 1401 is composed of an oblique groove and a linear groove, one end of the lateral push rod 13 is fixedly connected to the ejector rod 10, and the other end of the lateral push rod 13 is inserted into the push slide 1401. The end of the matching push strip 14 away from the oblique groove extends into the stripping module 8 and is fixedly connected to the cross plate 15, the cross plate 15 is limitedly slidably installed in the stripping module 8, and the end of the cross plate 15 away from the matching push strip 14 is fixedly connected to the inner clamping strip 16.

[0049] Furthermore, by providing a lateral push rod 13, cooperating with the push strip 14, pushing the slide groove 1401 and the cross plate 15 for use together, the inner clamping strip 16 can adaptively perform telescopic movement according to the movement state of the ejector rod 10. When the ejector rod 10 retracts inward, the inner clamping strip 16 extends outward to ensure the integrity of the surface of the stripping module 8; when the ejector rod 10 extends outward, the inner clamping strip 16 immediately retracts inward, thereby reducing the contact area between the injection molded part and the side wall of the stripping module 8, which helps to reduce the friction when the injection molded part is separated from the stripping module 8; and helps the injection molded part to be smoothly pulled out from the stripping module 8.

[0050] During injection molding, the movable mold 2 is pushed toward the fixed mold 1 by opening the hydraulic cylinder until the two are closely abutted against each other. During this process, the main push plate 4 is squeezed by the outer wall of the movable mold 2 and moves toward the inner side of the fixed mold 1. The longitudinal push strips 5 on the main push plate 4 act on the driving inclined groove 601, so that the connecting frame 6 is forced to drive the outer clamping strips 7 to extend outward to maintain the flatness of the side wall of the sink 101; then the heated and molten plastic original enters the molding cavity formed by the sink 101 and the stripping module 8 through the injection port, and finally forms the battery slot 42 injection molded part after cooling and finalization;

[0051] When demoulding, firstly, the movable film and the fixed mold 1 are gradually separated by opening the hydraulic cylinder again. In this process, the main push plate 4 is rapidly extended outward under the elastic force of the No. 1 spring 3, and the longitudinal push strip 5 on the main push plate 4 acts on the driving inclined groove 601 again, so that the connecting frame 6 is forced to drive the outer clamping strip 7 to retract inward, so that a plurality of rectangular grooves of regular size and uniform distribution appear on the side wall of the sink 101; thereby reducing the contact area between the injection molded part and the inner wall of the sink 101, helping to reduce the friction of the injection molded part when the stripping module 8 is separated from the fixed mold 1; helping the stripping module 8 to be smoothly pulled out of the sink 101; when the movable mold 2 is completely separated from the fixed mold 1, the longitudinal push cylinder 25 is opened to make its piston rod extend outward and push the cross movable plate 2 4 moves downward for a distance and then remains stationary. At this time, the cylindrical pin 23 on the cross movable plate 24 acts on the lateral inclined groove 22, so that the lateral movable plate 21 is forced to drive the lateral rack 20 to move toward the direction of the cross movable plate 24. The lateral rack 20 acts on the rotating wheel 19, so that the pressing arm 18 drives the two groups to rotate 90° and press the horizontal sides of the battery slot 42; then the active push cylinder 12 is turned on to push the ejector plate 11 to move toward the fixed mold 1, so that the outer pressure plate 17 can keep pressing the injection molded part laterally while also applying force with the ejector rod 10 to push the injection molded part out of the mold. This method of demoulding by combining the internal and external forces makes the demoulding process more stable and less prone to failure or jamming.

[0052] And ensure the continuity of production.

[0053] See also Figure 12 to Figure 14A device for processing and recycling edge burr waste is applied to a battery slot injection mold, including a recycling bin 31. A rectangular slot for accommodating the recycling bin 31 is opened at the lower end of an assembly seat 30 between a fixed mold 1 and a movable mold 2. The recycling bin 31 is driven by a linkage assembly and moves up and down in a straight line. The linkage assembly is driven by a transition push column 27; a circulation pipe 33 is arranged at the lower end of the recycling bin 31, and a bracket 34 and a receiving rod 36 are arranged on the top of the recycling bin 31 from left to right in sequence. A grinding wheel 35 is installed on the bracket 34, and a group of side baffles 32 are arranged on the front and rear sides of the recycling bin 31. The linkage assembly includes a fixed rack 37, a spur gear 38, a movable tooth plate 39, a No. 3 spring 40 and a driven push column 41. The fixed rack 37 is fixedly arranged on the side wall of the recovery bin 31. The spur gear 38 is limitedly slidably installed in the assembly seat 30 and its two sides are meshed and connected with the fixed rack 37 and the movable tooth plate 39 in turn. The lower end of the movable tooth plate 39 is fixedly connected to the No. 3 spring 40, and the upper end of the movable tooth plate 39 is fixedly connected to the driven push column 41. The driven push column 41 extends out of the top wall of the assembly seat 30 and is in contact with the transition push column 27.

[0054] Furthermore, through the design of the fixed rack 37, the spur gear 38, the movable tooth plate 39, the No. 3 spring 40 and the driven push pin 41, the downward pushing force of the transition push pin 27 can be converted into a linear up and down movement of the recovery bin 31, so that the outer pressure plate 17 can transport the demolded battery slot 42 downward while the grinding wheel 35 can move upward with the recovery bin 31, so that the burrs 43 on the battery slot 42 can be cut and polished, and the waste after cutting can fall into the recovery bin 31 for centralized processing, thereby avoiding secondary processing of the injection molded parts in subsequent operations and reducing labor and time costs.

[0055] When the battery slot 42 is completely separated from the stripping module 8, the active push cylinder 12 no longer operates; at this time, the top plate 11 remains in the position after the movement, and then the longitudinal push cylinder 25 continues to be opened, so that its piston rod continues to extend downward. At this time, the cylindrical pin 23 acts on the bottom wall of the lateral inclined groove 22, so that the lateral moving plate 21 is forced to drive the hinge seat 26 to move downward together, and the hinge seat 26 acts on the pressure arm 18, so that the outer pressure plate 17 continues to press the battery slot 42 and transport it downward together. In this process, the transition push column 27 is squeezed by the hinge seat 26 and extends into the assembly seat 30 and pushes the driven push column 41, which drives The movable tooth plate 39 squeezes the No. 3 spring 40 and moves downward. The movable tooth plate 39 acts on the fixed rack 37 through the spur gear 38, so that the fixed rack 37 is forced to drive the recovery bin 31 to move upward, and the grinding wheel 35 on the recovery bin 31 immediately moves upward and cuts and grinds the burrs 43 on the battery slot 42. The cut burrs 43 fall into the recovery bin 31 for centralized recycling and treatment; after the grinding of the battery slot 42 is completed, the longitudinal push cylinder 25 is opened again, so that the piston rod of the longitudinal push cylinder 25 retracts inward. At this time, the outer pressure plate 17 first drives the battery slot 42 to move upward, and then releases the battery slot 42 for the next processing step.
