Description

Technical Field

[0001] This invention relates to the field of injection molding equipment technology, and in particular to an automated molding equipment for an internally opened plastic part and its internally opened window. Background Technology

[0002] With the booming development of the construction industry, inward-opening windows are experiencing increasing market demand due to their aesthetic appeal and space-saving advantages, leading to a continuous rise in the demand for plastic fittings for inward-opening windows. Traditional molding methods for inward-opening window plastic fittings have many drawbacks. Manual operation is not only inefficient but also makes it difficult to guarantee the stability and consistency of product quality. Moreover, in the complex molding process that combines plastic fittings with metal parts, traditional processes struggle to meet the high-precision and refined production requirements.

[0003] Patent CN119502228A discloses an automated molding equipment for the production of plastic parts, relating to the field of injection molding technology. The equipment includes: a frame; a turntable; multiple sets of molds; an injection gun; a molded part; a shearing mechanism; and a lifting mechanism. During the rotation of the turntable, the molds can perform a first mold opening stroke and a second mold opening stroke. In the first mold opening stroke, only the two outer molds slide away from each other, exposing the two inner molds. After exposure, the rotation of the turntable passively causes the lifting mechanism to lower the shearing mechanism, causing the abutment plate to abut against the side wall of the inner mold. As the turntable rotates, the two cutters move closer to each other along an arc to cut the gate. After cutting, the second mold opening stroke opens the two inner molds, allowing the molded part with the cut gate to be unloaded. Then, the inner and outer molds are reset. This allows for immediate gate cutting after injection molding, reducing production steps and improving production efficiency.

[0004] The existing technology has the following drawbacks:

[0005] The inability to assemble metal parts simultaneously after plastic injection molding: Existing injection molding equipment mainly focuses on plastic molding and lacks the function of connecting with metal parts assembly. Metal parts assembly must be performed manually, which prolongs the overall production cycle. Moreover, manual operation is prone to deviations in the installation position of metal parts, affecting product quality and performance. Therefore, it is necessary to set up a structure that allows metal parts to be assembled simultaneously after plastic injection molding. This would improve the stability and consistency of product quality, reduce errors caused by manual operation, ensure accurate installation position of metal parts, promote the automation and intelligent development of production, make the production process more efficient and orderly, reduce labor costs, and improve production efficiency.

[0006] The existing equipment cannot be adjusted between pure plastic injection molding and insert injection molding: it can only perform a single type of injection molding and cannot quickly switch according to order requirements. When only pure plastic injection molding is needed, if the equipment can only perform insert injection molding, it will result in waste of insert material. Conversely, it will waste manpower and time for installing inserts, thus limiting the types of products that can be produced and making it difficult to meet diverse market demands. Therefore, a structure that can be set up to adjust between pure plastic injection molding and insert injection molding is needed to enhance production flexibility, allow for rapid switching of injection molding methods according to order requirements, respond promptly to market changes, avoid resource waste, rationally utilize materials, manpower and other resources under different injection molding requirements, reduce production costs, enrich product types, meet diverse market demands, and ultimately enhance the company's market competitiveness and economic benefits. Summary of the Invention

[0007] Given the problems of existing technologies, such as the inability to assemble metal parts simultaneously after plastic injection molding and the inability to adjust between pure plastic injection molding and insert injection molding, an automated molding equipment for internally opened plastic parts and its internal opening is proposed.

[0008] One aspect of this invention provides an automated molding equipment for internally opened window plastic parts. Its purpose is to: simultaneously assemble metal parts after the plastic part is injection molded via a moving mold mechanism and a fixed mold assembly, thereby improving product quality stability and consistency, reducing errors caused by manual operation, ensuring precise installation of metal parts, promoting the automation and intelligentization of production, making the production process more efficient and orderly, reducing labor costs, and improving production efficiency. Furthermore, it allows for adjustment between pure plastic injection molding and insert injection molding to enhance production flexibility, enabling rapid switching of injection molding methods according to order requirements, timely response to market changes, and avoiding resource waste. It also allows for the rational use of materials, manpower, and other resources under different injection molding needs, reducing production costs, enriching product variety, meeting diverse market demands, and ultimately enhancing the company's market competitiveness and economic benefits.

[0009] The technical solution of the present invention is as follows: an automated molding equipment for internally opened window plastic parts, including an equipment table, an injection molding device installed on the top of the equipment table and a mold closing assembly, the mold closing assembly including a mold adjusting device and a mold closing head plate fixedly installed on the top of the equipment table, and a mold closing middle plate slidably installed inside the mold adjusting device, a moving mold mechanism and a fixed mold assembly are provided between the mold closing head plate and the mold closing middle plate, and a hinge unit is provided between the moving mold mechanism and the fixed mold assembly;

[0010] The moving mold mechanism includes a moving mold base plate fixedly installed on the outer wall of the mold closing plate, a convex mold installed on the outer wall of the moving mold base plate, and a metal docking assembly provided between the moving mold base plate and the convex mold;

[0011] The metal docking assembly includes a first movable plate slidably connected to the inner wall of the moving mold base plate. The inner wall of the first movable plate is provided with a plurality of first sliding cavities and a plurality of second sliding cavities. The inner walls of the plurality of first sliding cavities are slidably connected with sliding modules. A telescopic spring is fixedly connected between the inner wall of the first sliding cavity and the outer wall of the sliding module. The inner wall of the sliding module is provided with an ejection hole.

[0012] Using the above scheme, through the set metal docking components, the mold adjustment device is operated. The mold adjustment device pushes the mold closing plate closer to the mold closing head plate, so that the convex mold and the fixed mold component on the moving mold base plate merge. The sliding module slides in the first sliding cavity until the sliding module, the convex mold, and the fixed mold component together form a cavity. Then, the injection molding device is operated to inject plastic into the cavity formed by the moving mold mechanism and the fixed mold component, forming the basic shape of the internally opened plastic part. When the production object is only a plastic part, the ejection component extends the sliding module to eject the part; when the production object is a part that combines plastic and metal parts, the sliding module is retracted under the rebound of the telescopic spring, and then the first movable plate is pushed so that the second sliding cavity is aligned with the plastic part, and the plastic and metal parts are merged. This allows the metal parts to be assembled simultaneously after the plastic parts are injected, thereby improving the stability and consistency of product quality, reducing errors caused by manual operation, ensuring the accurate installation position of the metal parts, promoting the automation and intelligent development of production, making the production process more efficient and orderly, reducing labor costs, and improving production efficiency.

[0013] Furthermore, the moving mold mechanism also includes an ejector cylinder fixedly installed on the outer wall of the mold adjusting device, and an ejector assembly disposed inside the moving mold base plate. The output end of the ejector cylinder is fixedly connected to an ejector rod, which is slidably installed inside the mold closing plate and the moving mold base plate.

[0014] Furthermore, the ejection assembly includes an ejection slide plate slidably connected to the inner wall of the moving mold base plate. The side of the ejection slide plate near the mold closing plate overlaps with the end of the ejection rod away from the ejection cylinder. A plurality of ejection pins are fixedly connected to the side of the ejection slide plate away from the mold closing plate.

[0015] Furthermore, a fixing block is fixedly connected to the outer wall of the ejector pin, a compression spring is fixedly connected to the outer wall of the fixing block, a movable block is fixedly connected to the end of the compression spring away from the fixing block, the movable block is slidably connected to the outer wall of the ejector pin, and the end of the ejector pin away from the ejector slide plate is slidably connected to the inner wall of the ejector hole.

[0016] Using the above scheme, the ejection assembly operates the ejection cylinder. The output end of the ejection cylinder pushes the ejection slide plate to slide within the moving mold base plate via the ejection rod. The ejection slide plate drives the ejection pin to penetrate the ejection hole. The movable block on the outer wall of the ejection pin, after contacting the sliding module, can push the sliding module to slide within the first sliding cavity until the sliding module, together with the convex mold and the concave mold, forms a cavity. When the production object is only a plastic part, the ejection pin, together with the fixing block, approaches the sliding module, the compression spring is compressed, and the ejection pin extends out of the sliding module to eject the part. When the production object is a part that combines plastic and metal parts, the ejection pin compresses the first and second metal parts in the second sliding cavity, causing the first and second metal parts to engage with the first and second plastic parts, thereby obtaining a part that combines plastic and metal parts.

[0017] Furthermore, the fixed mold assembly includes a fixed mold base plate fixedly installed on the outer wall of the mold closing head plate, a concave mold fixedly connected to the inner wall of the fixed mold base plate, and a second movable plate and a third movable plate slidably connected to the inner wall of the fixed mold base plate.

[0018] Furthermore, both the second and third movable plates have multiple sandwich modules slidably connected inside, and the inner wall of the second movable plate has multiple positioning blocks engaged.

[0019] Using the above scheme, the fixed mold assembly, sliding module, convex mold and concave mold together form a cavity. When the production object is an accessory with an embedded metal connecting shaft, the second movable plate is pulled out from inside the fixed mold base plate and the third movable plate is inserted. The metal connecting shaft is placed between the sandwich module and the positioning block in the third movable plate, and then injection molding is performed so that the metal connecting shaft is embedded in the second plastic part, thereby obtaining the accessory with the embedded metal connecting shaft. When the accessory is ejected, the sandwich module in the second or third movable plate will be ejected together. Then, the sandwich module on the accessory is removed and reinstalled on the second or third movable plate.

[0020] Furthermore, the hinge unit includes a first plastic part and a second plastic part that are snapped between the convex mold and the concave mold. A first metal part is snapped onto the inner wall of the first plastic part, and a second metal part is snapped onto the inner wall of the second plastic part. A connecting shaft is also installed on the inner wall of the second plastic part. The first plastic part and the second plastic part are rotatably connected through the connecting shaft.

[0021] Furthermore, both the first metal part and the second metal part are slidably connected to the inner wall of the second sliding cavity, and the connecting shaft is installed between the sandwich module and the positioning block.

[0022] Using the above scheme, through the hinge unit, when the production object is only a plastic part accessory, the first plastic part, the second plastic part, and the connecting shaft are cooled and formed in the cavity; when the production object is an accessory combining plastic and metal parts, the first plastic part, the second plastic part, and the connecting shaft are cooled and formed in the cavity, and the first metal part and the second metal part are inserted into the first plastic part and the second plastic part, thereby obtaining an accessory combining plastic and metal parts; when the production object is an accessory with an embedded metal connecting shaft, the metal connecting shaft is placed between the sandwich module and the positioning block in the third movable plate, and then injection molding is performed to embed the metal connecting shaft into the second plastic part, thereby obtaining an accessory with an embedded metal connecting shaft.

[0023] In another aspect, the present invention provides an inward-opening window using an automated molding equipment for plastic parts. The automated molding equipment for inward-opening window plastic parts includes a hinge unit, a window frame and an opening sash, wherein the window frame and the opening sash are hinged together by the hinge unit.

[0024] Using the above scheme, when assembling the inward-opening window, a first plastic part and a first metal part are installed at the outer frame of the window, and a second plastic part and a second metal part are installed at the opening sash. Then, the first plastic part and the second plastic part are hinged together through a connecting shaft to complete the assembly of the inward-opening window.

[0025] The beneficial effects of this invention are:

[0026] 1. By using the set metal docking components, when the production object is only a plastic part, the ejector component extends the sliding module to eject the part; when the production object is a part that combines plastic and metal parts, the sliding module retracts under the rebound of the telescopic spring, and then pushes the first movable plate to align the second sliding cavity with the plastic part, so as to merge the plastic and metal parts. This allows the metal parts to be assembled simultaneously after the plastic parts are injection molded, thereby improving the stability and consistency of product quality, reducing errors caused by manual operation, ensuring the accurate installation position of the metal parts, promoting the automation and intelligent development of production, making the production process more efficient and orderly, reducing labor costs, and improving production efficiency.

[0027] 2. Through the set ejection assembly, the ejection cylinder is operated. The output end of the ejection cylinder pushes the ejection slide plate to slide in the moving mold base plate via the ejection rod. The ejection slide plate drives the ejection pin to penetrate the ejection hole. The movable block on the outer wall of the ejection pin can push the sliding module to slide in the first sliding cavity after contacting the sliding module, until the sliding module forms a cavity together with the convex mold and the concave mold. When the production object is only a plastic part, the ejection pin and the fixing block approach the sliding module, the compression spring is compressed, and the ejection pin extends out of the sliding module to eject the part. When the production object is a part that combines plastic and metal parts, the ejection pin squeezes the first metal part and the second metal part in the second sliding cavity, so that the first metal part and the second metal part are engaged with the first plastic part and the second plastic part, thereby obtaining a part that combines plastic and metal parts.

[0028] 3. Through the set fixed mold assembly, the sliding module, together with the convex mold and the concave mold, forms a cavity. When the production object is an accessory with an embedded metal connecting shaft, the second movable plate is pulled out from inside the fixed mold base plate, and the third movable plate is inserted. The metal connecting shaft is placed between the sandwich module and the positioning block in the third movable plate, and then injection molding is performed so that the metal connecting shaft is embedded in the second plastic part, thereby obtaining the accessory with the embedded metal connecting shaft. When the accessory is ejected, the sandwich module in the second or third movable plate will be ejected together. Then, the sandwich module on the accessory is removed and reinstalled on the second or third movable plate. Attached Figure Description

Detailed Implementation

[0046] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0047] Example 1, referring to Figures 1-14The first embodiment of the present invention provides an automated molding equipment for internally opened window plastic parts, including a machine platform 1, an injection molding device 2 installed on the top of the machine platform 1 and a mold closing assembly 3. The mold closing assembly 3 includes a mold adjusting device 31 and a mold closing head plate 33 fixedly installed on the top of the machine platform 1, and a mold closing middle plate 32 slidably installed inside the mold adjusting device 31. A moving mold mechanism 4 and a fixed mold assembly 5 are provided between the mold closing head plate 33 and the mold closing middle plate 32, and a hinge unit 6 is provided between the moving mold mechanism 4 and the fixed mold assembly 5.

[0048] Reference Figures 6-8 The moving mold mechanism 4 includes a moving mold base plate 41 fixedly installed on the outer wall of the mold closing plate 32. A convex mold 42 is installed on the outer wall of the moving mold base plate 41. A metal docking assembly 43 is provided between the moving mold base plate 41 and the convex mold 42. The metal docking assembly 43 includes a first movable plate 431 slidably connected to the inner wall of the moving mold base plate 41. The inner wall of the first movable plate 431 is provided with a plurality of first sliding cavities 432 and a plurality of second sliding cavities 433. The inner walls of the plurality of first sliding cavities 432 are slidably connected with sliding modules 435. A telescopic spring 434 is fixedly connected between the inner wall of the first sliding cavity 432 and the outer wall of the sliding module 435. The inner wall of the sliding module 435 is provided with an ejection hole 436.

[0049] Specifically, the first movable plate 431 can slide flexibly on the inner wall of the moving mold base plate 41 and its position can be adjusted according to production needs; the ejection hole 436 is used for the ejection action of the subsequent ejection mechanism to facilitate the removal of the molded plastic parts from the mold; multiple metal parts can be installed inside the second sliding cavity 433 at the same time to reduce the frequency of operation.

[0050] The metal docking assembly 43 is used to operate the mold adjustment device 31. The mold adjustment device 31 pushes the mold closing plate 32 closer to the mold closing head plate 33, causing the convex mold 42 on the moving mold base plate 41 and the fixed mold assembly 5 to merge. The sliding module 435 slides in the first sliding cavity 432 until the sliding module 435, together with the convex mold 42 and the fixed mold assembly 5, forms a cavity. Then, the injection molding device 2 is operated to inject plastic into the cavity formed by the moving mold mechanism 4 and the fixed mold assembly 5, forming the basic shape of the internally opened plastic part. When the production object is only a plastic part, the ejector assembly 46 extends the sliding module. 435 ejects the accessory; when the production object is an accessory that combines plastic and metal parts, the sliding module 435 retracts under the rebound of the telescopic spring 434, and then pushes the first movable plate 431 so that the second sliding cavity 433 is aligned with the plastic part, and the plastic and metal parts are combined. This allows the metal parts to be assembled simultaneously after the plastic parts are injection molded, thereby improving the stability and consistency of product quality, reducing errors caused by manual operation, ensuring the accurate installation position of the metal parts, promoting the automation and intelligent development of production, making the production process more efficient and orderly, reducing labor costs, and improving production efficiency.

[0051] Reference Figures 9-11 The moving mold mechanism 4 also includes an ejector cylinder 44 fixedly installed on the outer wall of the mold adjusting device 31, and an ejector assembly 46 disposed inside the moving mold base plate 41. An ejector rod 45 is fixedly connected to the output end of the ejector cylinder 44. The ejector rod 45 is slidably installed inside the mold closing plate 32 and the moving mold base plate 41. The ejector assembly 46 includes an ejector slide plate 461 slidably connected to the inner wall of the moving mold base plate 41. The side of the ejector slide plate 461 closest to the mold closing plate 32 is opposite to the side of the ejector rod 45 furthest from the ejector cylinder 44. One end overlaps, and multiple ejector pins 462 are fixedly connected to the side of the ejector slide plate 461 away from the mold closing plate 32. A fixing block 463 is fixedly connected to the outer wall of the ejector pin 462. A compression spring 464 is fixedly connected to the outer wall of the fixing block 463. A movable block 465 is fixedly connected to the end of the compression spring 464 away from the fixing block 463. The movable block 465 is slidably connected to the outer wall of the ejector pin 462. The end of the ejector pin 462 away from the ejector slide plate 461 is slidably connected to the inner wall of the ejector hole 436.

[0052] Specifically, the side of the ejector slide plate 461 closest to the mold clamping plate 32 overlaps with the end of the ejector rod 45 away from the ejector cylinder 44. When the ejector rod 45 moves forward under the push of the ejector cylinder 44, it will push the ejector slide plate 461 to slide within the moving mold base plate 41. The end of the ejector pin 462 away from the ejector slide plate 461 is slidably connected to the inner wall of the ejector hole 436, so that the ejector pin 462 can accurately pass through the ejector hole 436 during the movement, and then act on the plastic part located in the mold cavity, so as to achieve the purpose of ejecting the plastic part from the mold, ensuring the efficient completion of the entire automated molding process.

[0053] The ejector assembly 46 is used to operate the ejector cylinder 44. The output end of the ejector cylinder 44 pushes the ejector slide plate 461 to slide within the moving mold base plate 41 via the ejector rod 45. The ejector slide plate 461 drives the ejector pin 462 to penetrate the ejector hole 436. The movable block 465 on the outer wall of the ejector pin 462 can push the sliding module 435 to slide within the first sliding cavity 432 after contacting the sliding module 435, until the sliding module 435, together with the convex mold 42 and the concave mold 52, forms a cavity. When the production object is only When producing plastic parts, the ejector pin 462, together with the fixing block 463, approaches the sliding module 435, compressing the spring 464 and causing it to contract. The ejector pin 462 then extends out of the sliding module 435 to eject the part. When producing parts that combine plastic and metal parts, the ejector pin 462 compresses the first metal part 62 and the second metal part 64 in the second sliding cavity 433, causing the first metal part 62 and the second metal part 64 to engage with the first plastic part 61 and the second plastic part 63, thereby obtaining parts that combine plastic and metal parts.

[0054] Reference Figures 12-14The fixed mold assembly 5 includes a fixed mold base plate 51 fixedly installed on the outer wall of the mold closing head plate 33. A concave mold 52 is fixedly connected to the inner wall of the fixed mold base plate 51. A second movable plate 53 and a third movable plate 54 are slidably connected to the inner wall of the fixed mold base plate 51. Multiple sandwich modules 55 are slidably connected inside the second movable plate 53 and the third movable plate 54. Multiple positioning blocks 56 are snapped into the inner wall of the second movable plate 53.

[0055] Specifically, the second movable plate 53 and the third movable plate 54 can slide freely on the inner wall of the fixed mold base plate 51 and be adjusted in position according to different production needs, so that the equipment can adapt to the production of various types of internal window plastic parts, improving the versatility and applicability of the equipment; the sandwich module 55 can provide additional support, positioning or shaping of specific structures in the cavity according to specific production processes and accessory requirements. The sliding connection of multiple sandwich modules 55 allows them to move flexibly inside the second movable plate 53 and the third movable plate 54, which is convenient for adjustment and replacement at different production stages to meet diverse production needs.

[0056] Through the fixed mold assembly 5, the sliding module 435, together with the convex mold 42 and the concave mold 52, forms a cavity. When the production object is an accessory with an embedded metal connecting shaft 65, the second movable plate 53 is pulled out from inside the fixed mold base plate 51, and the third movable plate 54 is inserted. The metal connecting shaft 65 is placed between the sandwich module 55 and the positioning block 56 in the third movable plate 54, and then injection molding is performed so that the metal connecting shaft 65 is embedded in the second plastic part 63, thereby obtaining an accessory with an embedded metal connecting shaft 65. When the accessory is ejected, the sandwich module 55 in the second movable plate 53 or the third movable plate 54 will be ejected together. Then, the sandwich module 55 on the accessory is removed and reinstalled on the second movable plate 53 or the third movable plate 54.

[0057] Reference Figures 4-5 The hinge unit 6 includes a first plastic part 61 and a second plastic part 63 that are snapped between the convex mold 42 and the concave mold 52. The inner wall of the first plastic part 61 is snapped with a first metal part 62, and the inner wall of the second plastic part 63 is snapped with a second metal part 64. A connecting shaft 65 is also installed on the inner wall of the second plastic part 63. The first plastic part 61 and the second plastic part 63 are rotatably connected by the connecting shaft 65. The first metal part 62 and the second metal part 64 are both slidably connected to the inner wall of the second sliding cavity 433. The connecting shaft 65 is installed between the sandwich module 55 and the positioning block 56.

[0058] With the hinge unit 6, when the production object is only a plastic part, the first plastic part 61, the second plastic part 63, and the connecting shaft 65 are cooled and formed in the cavity; when the production object is a part combining plastic and metal parts, the first plastic part 61, the second plastic part 63, and the connecting shaft 65 are cooled and formed in the cavity, and the first metal part 62 and the second metal part 64 are engaged with the first plastic part 61 and the second plastic part 63, thereby obtaining a part combining plastic and metal parts; when the production object is a part with a metal connecting shaft 65 embedded, the metal connecting shaft 65 is placed between the sandwich module 55 and the positioning block 56 in the third movable plate 54, and then injection molding is performed so that the metal connecting shaft 65 is embedded in the second plastic part 63, thereby obtaining a part with a metal connecting shaft 65 embedded.

[0059] During operation, the mold adjustment device 31 is activated, pushing the mold closing plate 32 closer to the mold closing head plate 33, causing the convex mold 42 on the moving mold base plate 41 and the concave mold 52 on the fixed mold base plate 51 to merge. The ejector cylinder 44 is activated, and its output end pushes the ejector slide plate 461 to slide within the moving mold base plate 41 via the ejector rod 45. The ejector slide plate 461 drives the ejector pin 462 to penetrate the ejector hole 436. The movable block 465 on the outer wall of the ejector pin 462, after contacting the sliding module 435, can push the sliding module 435 to slide within the first sliding cavity 432 until the sliding module 435, together with the convex mold 42 and the concave mold 52, forms a cavity. Then, the injection molding device 2 is activated to inject plastic into the cavity formed by the moving mold mechanism 4 and the fixed mold assembly 5. The plastic fills the convex mold 42 and the concave mold 52. The space between them forms the basic shape of the inward-opening plastic fitting; when the production object is only a plastic fitting, the ejection component 46 is directly run to eject the fitting; when the production object is a fitting that combines plastic and metal parts, the first metal part 62 and the second metal part 64 are first inserted into the first plastic part 61 and the second plastic part 63 to obtain a fitting that combines plastic and metal parts, and then the fitting is ejected; when the production object is a fitting with a metal connecting shaft 65 embedded in it, the metal connecting shaft 65 is first embedded into the second plastic part 63 to obtain a fitting with a metal connecting shaft 65 embedded in it, and then the fitting is ejected. When the fitting is ejected, the sandwich module 55 in the second movable plate 53 or the third movable plate 54 will be ejected together. Then, the sandwich module 55 on the fitting is removed and reinstalled on the second movable plate 53 or the third movable plate 54.

[0060] Example 2, refer to Figure 15 The second embodiment of the present invention provides an inward-opening window using an automated molding equipment for plastic parts. The automated molding equipment for inward-opening window plastic parts includes a hinge unit 6, a window outer frame 7, and an opening sash 8. The window outer frame 7 and the opening sash 8 are hinged together by the hinge unit 6.

[0061] During use, when assembling the inward-opening window, the first plastic part 61 and the first metal part 62 are installed at the outer frame 7 of the window, and the second plastic part 63 and the second metal part 64 are installed at the opening sash 8. Then, the first plastic part 61 and the second plastic part 63 are hinged together through the connecting shaft 65 to complete the assembly of the inward-opening window.

[0062] Working principle of the invention:

[0063] During operation, the mold adjustment device 31 is activated, which pushes the mold closing plate 32 closer to the mold closing head plate 33, causing the convex mold 42 on the moving mold base plate 41 and the concave mold 52 on the fixed mold base plate 51 to merge. The ejection cylinder 44 is activated, and the output end of the ejection cylinder 44 pushes the ejection slide plate 461 to slide within the moving mold base plate 41 via the ejection rod 45. The ejection slide plate 461 drives the ejection pin 462 to penetrate the ejection hole 436. After contacting the sliding module 435, the movable block 465 on the outer wall of the ejection pin 462 can push the sliding module 435 to slide within the first sliding cavity 432 until the sliding module 435, together with the convex mold 42 and the concave mold 52, forms a cavity.

[0064] Next, the injection molding device 2 injects plastic into the cavity formed by the moving mold mechanism 4 and the fixed mold assembly 5. The plastic fills the space between the convex mold 42 and the concave mold 52, forming the basic shape of the internally opened plastic part.

[0065] When the production object is only a plastic part, the first plastic part 61, the second plastic part 63 and the connecting shaft 65 are cooled and formed in the cavity. First, the mold adjustment device 31 and the ejector cylinder 44 are reversed to open the cavity. Then, the ejector cylinder 44 continues to run. The ejector pin 462, together with the fixing block 463, approaches the sliding module 435. The compression spring 464 is compressed by force, and the ejector pin 462 extends out of the sliding module 435 to eject the part.

[0066] When producing an accessory that combines plastic and metal parts, the first plastic part 61, the second plastic part 63, and the connecting shaft 65 are cooled and formed in the cavity. First, the ejector cylinder 44 is reversed, and the sliding module 435 is retracted under the rebound of the telescopic spring 434. Then, the first movable plate 431 is pushed so that the second sliding cavity 433 is aligned with the plastic part. Then, the ejector cylinder 44 continues to run, and the ejector pin 462 squeezes the first metal part 62 and the second metal part 64 in the second sliding cavity 433, so that the first metal part 62 and the second metal part 64 are engaged with the first plastic part 61 and the second plastic part 63, thereby obtaining an accessory that combines plastic and metal parts. Finally, the mold adjusting device 31 and the ejector cylinder 44 are reversed to open the cavity and eject the accessory.

[0067] When the production object is an accessory with an embedded metal connecting shaft 65, the second movable plate 53 is pulled out from inside the fixed mold base plate 51, and the third movable plate 54 is inserted. The metal connecting shaft 65 is placed between the sandwich module 55 and the positioning block 56 in the third movable plate 54, and then injection molding is performed so that the metal connecting shaft 65 is embedded in the second plastic part 63, thereby obtaining the accessory with the embedded metal connecting shaft 65.

[0068] When the accessory is ejected, the sandwich module 55 inside the second movable plate 53 or the third movable plate 54 will also be ejected. Then, remove the sandwich module 55 from the accessory and reinstall it onto the second movable plate 53 or the third movable plate 54.

[0069] When assembling the inward-opening window, the first plastic part 61 and the first metal part 62 are installed at the outer frame 7 of the window, and the second plastic part 63 and the second metal part 64 are installed at the opening sash 8. Then, the first plastic part 61 and the second plastic part 63 are hinged together through the connecting shaft 65 to complete the assembly of the inward-opening window.
