Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, specifically to an injection mold for a learning machine panel. Background Technology

[0002] Injection molding is a highly efficient and precise plastic molding method widely used in the manufacture of components such as electronic device housings. With the continuous advancement of plastic processing technology, the design and manufacturing requirements for injection molds are becoming increasingly stringent, demanding that molds achieve high-precision molding, efficient production, and excellent product quality.

[0003] Since learning machine panels typically have high appearance requirements, requiring a smooth, flat surface free of scratches and damage, some existing demolding mechanisms, such as push rod demolding, may directly contact and rub against the panel surface during demolding if the push rod position is not properly designed or the push rod end surface is not smooth enough, thus leaving push rod marks or scratches on the panel surface and affecting the appearance quality of the panel. Therefore, we propose an injection mold for learning machine panels. Utility Model Content

[0004] The purpose of this invention is to provide an injection mold for a learning machine panel to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an injection mold for a learning machine panel, comprising a base plate, a concave mold disposed on the top of the base plate, and a convex mold disposed on the top of the concave mold, and further comprising:

[0006] A demolding assembly includes a support plate fixed to the top of a base plate, a rotating rod rotatably connected to the support plate, the rotating rod being fixedly connected to a die, a gear being provided on the rotating rod, a first sliding groove being provided on the support plate, a first slider being slidably connected in the first sliding groove, a rack being connected to the first slider, and the rack being meshed with the gear.

[0007] The power assembly includes a take-up roller rotatably connected to the top of the base plate. A housing is provided on the top of the take-up roller, and a motor is provided inside the housing. The take-up roller is fixedly connected to the output end of the motor. A connecting rope is sleeved on the take-up roller, and a push block is connected to the connecting rope.

[0008] Furthermore, a second sliding groove is provided on the top of the base plate near the push block, and a second slider is slidably connected in the second sliding groove. The push block is fixedly connected to the second slider.

[0009] The above technical solution is adopted: by setting a second slide and a second slider, the push block is limited to prevent it from deviating from its original motion trajectory during the movement.

[0010] Furthermore, a reset assembly is provided on the top side of the base plate near the push block. The reset assembly includes an extension plate, on which a spring is fixedly connected. A limit plate is provided on the top side of the base plate near the spring, and the end of the spring away from the extension plate is fixedly connected to the limit plate.

[0011] The above technical solution involves setting up a reset component to automatically reset the die after demolding, without the need for manual intervention.

[0012] Furthermore, a pressing assembly is provided on the top side of the base plate near the die cavity. The pressing assembly includes a guide post, a top plate is provided on the top of the guide post, and a hydraulic cylinder is provided on the top of the top plate. The output end of the hydraulic cylinder is fixedly connected to the punch.

[0013] The above technical solution ensures that plastic fills every corner of the mold cavity by setting up a pressing component, thereby improving the dimensional accuracy and surface quality of the product.

[0014] Furthermore, the die is provided with a cooling assembly, which includes a through hole and a sealing cap is threaded to the top of the through hole.

[0015] The above technical solution involves setting up cooling components to control the temperature of the mold, allowing the plastic melt to be formed under suitable temperature conditions, thereby improving the quality of the products and production efficiency.

[0016] Furthermore, a receiving box is provided on the top of the base plate, and a soft pad is provided inside the receiving box. The receiving box is located at the bottom of the concave mold.

[0017] The above technical solution involves setting up a receiving box to receive the model after demolding, and a soft pad to protect the model from damage.

[0018] Furthermore, sliding plates are provided on both sides of the punch, and the sliding plates are slidably connected to the guide post.

[0019] The above technical solution is adopted: by setting a sliding plate, the punch and die can be accurately aligned during mold closing to prevent misalignment.

[0020] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0021] In this invention, by setting a demolding component, unlike demolding mechanisms that involve direct contact such as push rods, gravity demolding does not require direct contact with the surface of the learning machine panel to apply demolding force. This effectively avoids leaving marks on the panel surface due to contact friction. It solves the problem that some existing demolding mechanisms, such as push rod demolding, may directly contact the panel surface and generate friction during the demolding process if the push rod position is not properly designed or the push rod end surface is not smooth enough, thus leaving push rod marks or scratches on the panel surface and affecting the appearance quality of the panel.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] like Figures 1-3 As shown, this utility model provides a technical solution: an injection mold for a learning machine panel, including a base plate 1, a concave mold 2 disposed on the top of the base plate 1, and a convex mold 3 disposed on the top of the concave mold 2, and further including:

[0036] The demolding assembly 4 includes a support plate 41 fixed to the top of the base plate 1, a rotating rod 42 rotatably connected to the support plate 41, the rotating rod 42 being fixedly connected to the cavity mold 2, a gear 43 being provided on the rotating rod 42, a first sliding groove 45 being provided on the support plate 41, a first slider 46 being slidably connected in the first sliding groove 45, a rack 44 being connected to the first slider 46, the rack 44 being meshed with the gear 43, a receiving box 10 being provided at the top of the base plate 1, a soft pad being provided inside the receiving box 10, and the receiving box 10 being located at the bottom of the cavity mold 2;

[0037] The power assembly 5 includes a take-up roller 51 rotatably connected to the top of the base plate 1. A housing 52 is provided on the top of the take-up roller 51. A motor is provided inside the housing 52. The take-up roller 51 is fixedly connected to the output end of the motor. A connecting rope 53 is sleeved on the take-up roller 51. A push block 54 is connected to the connecting rope 53.

[0038] Specifically, when demolding is required, the motor is turned on to drive the take-up roller 51 to rotate. The take-up roller 51 drives the connecting rope 53 to wind up, and the connecting rope 53 drives the push block 54 to move. Since the side of the push block 54 away from the take-up roller 51 is higher, the sliding of the push block 54 will drive the rack 44 to slide upward through the first slider 46 in the first groove 45. The rack 44 will drive the gear 43 to rotate, and the gear 43 will drive the rotating rod 42 to rotate. The rotating rod 42 will drive the die 2 to rotate, so that the model is demolded by gravity and falls into the receiving box 10 at the bottom.

[0039] Furthermore, such as Figure 1 As shown: A pressing assembly 7 is provided on the top side of the base plate 1 near the die 2. The pressing assembly 7 includes a guide post 72. A top plate 73 is provided on the top of the guide post 72. A hydraulic cylinder 71 is provided on the top of the top plate 73. The output end of the hydraulic cylinder 71 is fixedly connected to the punch 3. Sliding plates 74 are provided on both sides of the punch 3. The sliding plates 74 are slidably connected to the guide post 72. When the hydraulic cylinder 71 is opened, the punch 3 slides on the guide post 72 through the sliding plates 74 on both sides, and closes with the die 2.

[0040] The above solution also has the problem that the pusher block 54 may shift during its movement, such as... Figure 3 As shown: A second slide groove 9 is provided on the top side of the base plate 1 near the push block 54. A second slider is slidably connected in the second slide groove 9. The push block 54 is fixedly connected to the second slider. When the push block 54 moves, it will synchronously drive the second slider to slide in the second slide groove 9, thereby limiting the movement trajectory of the push block 54.

[0041] The above solution also has the problem that after demolding is completed, the die 2 cannot automatically reset, such as... Figure 3 As shown: A reset assembly 6 is provided on the top side of the base plate 1 near the push block 54. The reset assembly 6 includes an extension plate 61, on which a spring 62 is fixedly connected. A limit plate 63 is provided on the top side of the base plate 1 near the spring 62. The end of the spring 62 away from the extension plate 61 is fixedly connected to the limit plate 63. The spring force of the spring 62 will drive the push block 54 to automatically spring back to its original position, so that the rack 44 slides down due to gravity. During the slide, the gear 43 is rotated to reset the die 2.

[0042] Furthermore, such as Figure 4 As shown: A cooling component 8 is provided on the cavity mold 2. The cooling component 8 includes a through hole 81, and a sealing cap 82 is threadedly connected to the top of the through hole 81. By setting the cooling component 8, the temperature of the mold is controlled, so that the plastic melt is formed under suitable temperature conditions, thereby improving the quality of the product and production efficiency.

[0043] The working principle provided by this utility model is as follows: Figures 1-4 As shown: First, the hydraulic cylinder 71 is activated, causing the punch 3 to slide on the guide post 72 via the sliding plates 74 on both sides, closing with the die 2. When demolding is required, the motor is activated to drive the take-up roller 51 to rotate. The take-up roller 51 drives the connecting rope 53 to wind up, and the connecting rope 53 drives the push block 54 to move. During the movement of the push block 54, it will simultaneously drive the second slider to slide in the second slide groove 9, thereby limiting the movement trajectory of the push block 54. Since the side of the push block 54 away from the take-up roller 51 is higher... Subsequently, the sliding of the push block 54 will cause the rack 44 to slide upward through the first slider 46 in the first groove 45. The rack 44 will drive the gear 43 to rotate, the gear 43 will drive the rotating rod 42 to rotate, and the rotating rod 42 will drive the die 2 to rotate, so that the model will be demolded by gravity and fall into the receiving box 10 at the bottom. After demolding, the elastic force of the spring 62 will drive the push block 54 to automatically spring back to its original position, so that the rack 44 will slide down by gravity. During the sliding process, the gear 43 will rotate to reset the die 2.

[0044] 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 way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. The implementation schemes in the above embodiments can also be further combined or replaced. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
