Description

Technical Field

[0001] This utility model relates to the field of injection molding machine technology, specifically a modular injection molding machine for small-batch customized production. Background Technology

[0002] Injection molding machines are primary molding equipment used to produce various shapes of plastic products from thermoplastic or thermosetting plastics using plastic molds. Their working principle involves heating the plastic raw material to melt it, then using the thrust of a screw or plunger to inject the molten plastic into a closed mold cavity. After cooling and solidification, a plastic product conforming to the shape of the mold cavity is obtained. They are widely used in numerous industries such as automotive, electronics, home appliances, and packaging, enabling efficient and mass production of various plastic parts and products.

[0003] With the surge in personalized demand in the current consumer market, small-batch customized plastic products are widely used in jewelry, home furnishings, medical devices, electronics, and other fields. However, traditional injection molding machines are usually designed for large-scale standardized production. Their structures are fixed, their functional modules are highly integrated, and they lack adjustability, making it difficult to adapt to new demands. Utility Model Content

[0004] The purpose of this invention is to provide a modular injection molding machine for small-batch customized production, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows.

[0006] A modular injection molding machine for small-batch customized production includes a cabinet, a mold clamping module, and an injection module. The mold clamping module is mounted on one side of the upper surface of the cabinet by a first bolt. A recessed section is provided on the other side of the upper surface of the cabinet. A support plate is mounted on the surface of the recessed section via a lifting mechanism, which can adjust the height of the support plate. The injection module is mounted on the upper surface of the support plate by a second bolt.

[0007] Therefore, by dividing the injection molding machine into three independent modules—the cabinet, the mold clamping module, and the injection module—each module can be replaced individually. This allows for the replacement of the corresponding module according to production needs, resulting in high adjustability. This can meet the production needs of small-batch customization, and the modules can also be transported separately, reducing transportation difficulties.

[0008] Furthermore, the lifting mechanism includes two parallel fixed plates mounted on the surface of the recessed portion. A first threaded rod with a pair of reverse threads is rotatably mounted between the two fixed plates, and a movable plate is mounted on each of the two reverse threads of the first threaded rod. Support plates are hinged to both sides of the upper surface of the movable plate, and the ends of the support plates are hinged to the lower surface of the support plate. When the first threaded rod is rotated, the support plate can be raised or lowered, thereby adjusting the height of the injection module.

[0009] Furthermore, multiple guide posts are installed on the upper surface of the recessed section, and the support plate is slidably mounted on the guide posts via linear bearings. This ensures that the support plate remains horizontal and prevents uneven stress on the support plate due to tilting, which could lead to deformation or damage.

[0010] Furthermore, multiple second threaded rods are installed on the upper surface of the recessed section. Through holes are formed on the bearing plate corresponding to the second threaded rods, and the second threaded rods are inserted into these through holes, with the diameter of the through holes being larger than the diameter of the second threaded rods. Nuts are installed on the outer surfaces of the second threaded rods on both the upper and lower sides of the bearing plate. This allows the bearing plate to be locked in position, reducing the load on the support plate and improving the overall structural stability.

[0011] Furthermore, one end of the first threaded rod extends to the outside of the fixing plate and is fitted with a handle, which is located on the outside of the cabinet along its length. A bearing seat is installed on the outer surface of the first threaded rod near the handle, and the bottom of the bearing seat is connected to the upper surface of the recessed part. This facilitates the rotation of the first threaded rod and prevents bending deformation caused by axial and radial forces during handle rotation.

[0012] Furthermore, two parallel slide rails are installed between the two fixed plates, and the movable plate is slidably mounted on the slide rails. This allows the first threaded rod to provide only the driving force, without bearing the weight of the support plate and injection module.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows.

[0014] 1. This utility model divides the injection molding machine into three independent modules: the cabinet, the mold clamping module, and the injection module. Each module can be replaced individually, allowing for the replacement of the corresponding module parts according to production needs. This provides high adjustability, meets the production needs of small-batch customization, and can also be transported separately, reducing transportation difficulties.

[0015] 2. This utility model adjusts the height of the injection module through a lifting mechanism, ensuring that the injection end of the injection module is at the same height as the injection port of the mold closing module when changing mold closing modules of different specifications, thus ensuring injection accuracy. It can adapt to mold closing modules of different specifications and meet customers' customization needs. Attached Figure Description

[0018] 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.

[0019] like Figure 1-4 As shown, a modular injection molding machine for small-batch customized production includes a cabinet 1, a mold clamping module 2, and an injection module 3. The mold clamping module 2 is mounted on one side of the upper surface of the cabinet 1 by a first bolt 201. A recessed portion 102 is provided on the other side of the upper surface of the cabinet 1. A support plate 101 is mounted on the surface of the recessed portion 102 via a lifting mechanism 4, which can adjust the height of the support plate 101. The injection module 3 is mounted on the upper surface of the support plate 101 by a second bolt 301.

[0020] By dividing the injection molding machine into three independent modules—cabinet 1, mold clamping module 2, and injection module 3—each module can be replaced individually. This allows for the replacement of the corresponding module according to production needs, providing high adjustability and meeting the production requirements of small-batch customization. Furthermore, the modules can be transported separately, reducing transportation difficulties. The height of injection module 3 can be adjusted via lifting mechanism 4, ensuring that the injection end of injection module 3 is at the same height as the injection port of mold clamping module 2 when changing to different specifications of mold clamping module 2. This guarantees injection accuracy and can adapt to different specifications of mold clamping module 2, meeting customers' customization needs.

[0021] Preferably, the lifting mechanism 4 includes two parallel fixed plates 401 mounted on the surface of the recessed portion 102. A first threaded rod 402 with a pair of reverse threads is rotatably mounted between the two fixed plates 401. A movable plate 403 is mounted on each of the two reverse threads of the first threaded rod 402. Support plates 404 are hinged to both sides of the upper surface of the movable plate 403, and the ends of the support plates 404 are hinged to the lower surface of the bearing plate 101.

[0022] When the first threaded rod 402 is rotated, the two moving plates 403 can be driven to move closer or further apart under the action of the reverse thread. At this time, the support angles of the four support plates 404 change synchronously, which in turn drives the bearing plate 101 to rise and fall, thereby adjusting the height of the injection module 3.

[0023] When the two moving plates 403 approach each other, the height of the injection module 3 is raised. When the two moving plates 403 descend, the height of the injection module 3 decreases. Due to the threaded connection, the adjustment accuracy is high, which can ensure that the injection end of the injection module 3 corresponds precisely to the injection port of the mold closing module 2.

[0024] Preferably, a plurality of guide posts 5 are installed on the upper surface of the recessed portion 102, and the bearing plate 101 is slidably mounted on the guide posts 5 via a linear bearing 501.

[0025] By setting the guide column 5 and the linear bearing 501, the support plate 101 can be accurately guided when it is raised and lowered, ensuring that the position of the support plate 101 remains horizontal and avoiding uneven force on the support plate 404 due to tilting, which may cause deformation or damage.

[0026] Preferably, a plurality of second threaded rods 6 are installed on the upper surface of the recessed portion 102, and through holes 601 are provided on the bearing plate 101 corresponding to the second threaded rods 6, with the second threaded rods 6 inserted into the through holes 601, and the diameter of the through holes 601 being larger than the diameter of the second threaded rods 6. Nuts 602 are installed on both the upper and lower sides of the outer surface of the second threaded rods 6 on the bearing plate 101.

[0027] When the support plate 101 is raised or lowered, it moves up and down on the outside of the second threaded rod 6. After the height of the injection module 3 is adjusted, the two nuts 602 on the second threaded rod 6 are turned to make them abut against the upper and lower sides of the support plate 101, thereby locking the position of the support plate 101, reducing the load on the support plate 404 and improving the stability of the overall structure.

[0028] Preferably, one end of the first threaded rod 402 extends to the outside of the fixing plate 401 and is fitted with a handle 406, with the handle 406 located on the outside of the cabinet 1 along its length. A bearing seat 407 is installed on the outer surface of the first threaded rod 402 near the handle 406, and the bottom of the bearing seat 407 is connected to the upper surface of the recessed portion 102.

[0029] The handle 406 facilitates the rotation of the first threaded rod 402, improving the portability of the height adjustment of the injection module 3. The bearing seat 407 provides stable support for the first threaded rod 402, ensuring it maintains linear motion during rotation, reducing offset and wobbling, and preventing bending and deformation of the first threaded rod 402 due to axial and radial forces during the rotation of the handle 406.

[0030] Preferably, two parallel slide rails 405 are installed between the two fixed plates 401, and the movable plate 403 is slidably installed on the slide rails 405.

[0031] By setting the slide rail 405, not only is the moving plate 403 moved more smoothly, but it also plays a load-bearing role, so that the first threaded rod 402 only provides driving force and does not need to bear the weight of the bearing plate 101 and the injection module 3, thus ensuring the stable use of the overall structure.

[0032] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art.

For those skilled in the art, any equivalent substitutions or obvious modifications made without departing from the concept of the present invention, and which have the same performance or use, should be considered as falling within the patent protection scope defined by the submitted claims.
