[0025] The embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0026] It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a central component at the same time. When a component is considered to be "located on" another component, it may be directly located on the other component or there may be a central component at the same time.

[0027] An embodiment of the present application provides an injection molding machine for producing molds, including a base, an injection molding mechanism and a heating assembly, wherein the length direction of the base is defined as a first direction. The injection molding mechanism is disposed on the base surface and arranged along the first direction, including an injection molding head, a connecting tube and a push rod, wherein the injection molding head and the push rod are respectively disposed at both ends of the connecting tube. One end of the heating assembly is disposed on the injection molding mechanism, and the other end is disposed obliquely upward away from the base, including a discharge pipe and a heating pipe that are interconnected, wherein the discharge pipe is disposed at one end of the connecting tube close to the injection molding head, and is connected to the connecting tube.

[0028] The above-mentioned injection molding machine for producing molds can reduce the influence of heat on the injection molding component by designing the heating component and the injection molding component as independent units. Such a design can reduce the thermal stress of the injection molding component caused by heating, thereby extending the service life of the injection molding component; separating the heating component and the injection molding component can better control the working temperature of each component. This helps to ensure that the injection molding component works under lower temperature conditions, reduces the risk of thermal deformation, and thus improves the stability of the injection molding component.

[0029] Some embodiments of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0030] See also Figure 1-Figure 3 , an embodiment of the present application provides an injection molding machine 100 for producing a mold, comprising:

[0031] The base 10 defines a length direction of the base 10 as a first direction;

[0032] The injection molding mechanism 20 is arranged on the table surface of the base 10 and arranged along the first direction, and includes an injection molding head 21, a connecting tube 22 and a push rod 23. The injection molding head 21 and the push rod 23 are respectively arranged at two ends of the connecting tube 22;

[0033] The heating assembly 30 has one end disposed on the injection molding mechanism 20 and the other end disposed obliquely upward away from the base 10, and includes a discharge pipe 31 and a heating pipe 32 that are interconnected. The discharge pipe 31 is disposed at one end of the connecting pipe 22 close to the injection molding head 21 and is connected to the connecting pipe 22.

[0034] Specifically, the base 10 provides a stable support for the entire injection molding machine. The various components of the injection molding machine are mounted on the base 10, and the relative positions are kept stable by the base 10 to ensure the accuracy and stability of the injection molding process. The injection molding mechanism 20 is a core component, including an injection head 21, a connecting pipe 22 and a push rod 23, which are used to inject plastic particles into the mold for molding. It can effectively transport plastic into the mold and ensure that appropriate pressure is applied during the injection molding process to ensure the molding quality and dimensional accuracy of the product.

[0035] Furthermore, the heating assembly 30 is located above the injection molding mechanism 20, and melts the plastic particles to a state suitable for injection molding by heating. By independently setting up the heating assembly 30, the thermal stress on the injection molding assembly is reduced, and the service life of the injection molding assembly is extended. The heating pipe 32 provides heat energy, so that the plastic particles gradually melt and flow to the discharge pipe 31, and then are transported to the injection head 21 for molding.

[0036] Furthermore, by independently setting up the heating component 30, the injection molding machine solves the problem caused by the integration of the heating component 30 and the injection molding component in the existing injection molding machine. Separating the heating component 30 and the injection molding component reduces the thermal stress on the injection molding component, prolongs its service life, and improves the stability and precision of the injection molding process.

[0037] In a specific embodiment, the heating component 30 further includes a baffle 33 , which is disposed on the discharge pipe 31 and extends into the discharge pipe 31 , and the maximum extension length of the baffle 33 is less than the diameter of the discharge pipe 31 .

[0038] Specifically, the baffle 33 is disposed on the discharge pipe 31 and extends into the discharge pipe 31, and its function is to prevent or limit the uncontrolled flow of the plastic particles during the heating process, so that they move along the expected path. By providing the baffle 33, the flow direction and speed of the plastic particles can be controlled to ensure that they are evenly heated and melted, thereby improving the efficiency and stability of the heating process. When the heating component 30 starts to heat and process the plastic particles, the baffle 33 is located in the discharge pipe 31, blocking the flow of the plastic particles. The length of the baffle 33 is less than the diameter of the discharge pipe 31, which means that it will not completely block the discharge pipe 31, but allow the plastic particles to flow along the pipe to ensure sufficient heating and melting.

[0039] Furthermore, the baffle 33 is located inside the discharge pipe 31, and its design allows the plastic particles to be controlled during the heating process, ensuring that they are evenly heated and melted under the action of the heating pipe 32. This helps to prevent unmelted or unevenly melted plastic particles from flowing out of the discharge pipe 31, ensuring the quality and stability of the molded product. The setting of the baffle 33 allows the plastic particles to flow only along the expected path, ensuring the effectiveness of the heating process and avoiding production problems caused by insufficient melting of the plastic particles.

[0040] In a specific embodiment, the injection molding machine further includes a feeding piece 40 , which is disposed on the heating assembly 30 , communicated with the heating tube 32 , and located above the baffle 33 .

[0041] Specifically, the feeder 40 is located above the heating assembly 30, connected to the heating pipe 32, and located above the baffle 33. Its function is to transport the melted plastic particles from the heating assembly 30 to the injection head 21 to further complete the injection molding process. The feeder 40 ensures that the melted plastic particles can be smoothly and evenly transported to the injection head 21, which helps to improve the efficiency and stability of the injection molding process and ensure the quality of the molded product.

[0042] Further, when the heating assembly 30 starts to heat and melt the plastic particles, the molten plastic particles flow to the feeder 40 through the heating pipe 32. The feeder 40 is connected to the heating pipe 32 to transport the molten plastic particles to the injection head 21, ready to be injected into the mold for molding.

[0043] In a specific embodiment, the heating assembly 30 further includes an adjusting column 34 , and the adjusting column 34 is movably disposed in the heating tube 32 to adjust the feeding rate of the feeding member 40 .

[0044] Specifically, the adjusting column 34 is a movable component in the heating assembly 30, located in the heating tube 32, and its function is to adjust the feeding rate of the feeding member 40. The adjusting column 34 can flexibly adjust the feeding rate of the feeding member 40 to meet the requirements of different injection molding products, improve the flexibility and controllability of the injection molding process, and thus optimize the quality and production efficiency of the molded products.

[0045] Furthermore, the adjusting column 34 can adjust the contact degree with the feeding member 40 by moving in the heating tube 32, thereby changing the feeding rate of the feeding member 40. When the adjusting column 34 is in different positions, the contact area with the feeding member 40 is different, resulting in different pressures inside the barrel, which in turn affects the pressure and flow rate of the molten plastic particles in the barrel, thereby adjusting the feeding rate.

[0046] In a specific embodiment, the injection molding machine also includes a shaping device 50 arranged along the first direction, including a demolding structure 51 and a first template 52 and a second template 53 that are attached to each other, the first template 52 is attached to the injection head 21 and is provided with a feed hole 52a, and the demolding structure 51 is arranged on a side close to the second template 53.

[0047] Specifically, the shaping device 50 is located between the heating component 30 and the mold of the injection molding machine, and is used to shape the injection molded product. The design of the shaping device 50 makes the injection molding process more stable and accurate, and can ensure the dimensional accuracy and surface quality of the molded product. During the injection molding process, the heating component 30 heats the plastic particles to melt them, and then the molten plastic enters the shaping device 50 through the injection molding head 21. The first template 52 and the second template 53 are attached to each other to clamp the plastic, and the demolding structure 51 is located on one side of the second template 53 to assist in demolding the molded product.

[0048] Furthermore, the first template 52 is a component of the shaping device 50, and is fitted with the second template 53, and is responsible for clamping the plastic and positioning the feed hole 52a. The design of the first template 52 ensures the dimensional accuracy and surface quality of the injection molded product, and provides an accurate position for the feeding of plastic particles. During the injection molding process, the first template 52 and the second template 53 are fitted with each other to clamp the plastic particles. The feed hole 52a provides a feeding channel for the molten plastic.

[0049] Furthermore, the demoulding structure 51 is located on one side of the second template 53, and is used to assist in demoulding the molded product. The existence of the demoulding structure 51 ensures that the molded product can be smoothly separated from the mold, reducing damage and defects during the molding process. When the molded product is completed, the demoulding structure 51 smoothly removes the molded product from the mold through corresponding actions.

[0050] In a specific embodiment, the shaping device 50 further includes a slide rail 54 , one end of which is disposed on the base 10 , and the other end of which is connected to the shaping device 50 to drive the shaping device 50 to move along the first direction.

[0051] Specifically, the slide rail 54 is a component of the shaping device 50, and is used to support and guide the shaping device 50 to move along the first direction. The slide rail 54 enables the shaping device 50 to move stably and accurately during the injection molding process, thereby ensuring the dimensional accuracy and surface quality of the molded product. When the injection molding process starts, the shaping device 50 on the slide rail 54 is activated and moves along the first direction through the slide rail 54. One end is fixed on the base 10, and the other end is connected to the shaping device 50, so that it can move smoothly along the specified direction.

[0052] In a specific embodiment, the demoulding structure 51 includes a demoulding member 511 and a pushing member 512, wherein the pushing member 512 is attached to the demoulding member 511, and the demoulding member 511 is disposed on the second template 53:

[0053] When the shaping device 50 moves along the first direction, the first template 52 and the second template 53 are separated, the slide rail 54 continues to move along the first direction, and the pushing member 512 pushes the demoulding member 511 to make the finished product fall off.

[0054] Specifically, the demoulding structure 51 includes a demoulding member 511 and a pushing member 512, which are used to remove the finished product from the mold after molding is completed. The design of the demoulding structure 51 allows the finished product to be smoothly separated from the mold, thereby ensuring the integrity and quality of the molded product. During the injection molding process, when the shaping device 50 moves along the first direction, the first template 52 and the second template 53 are separated, and the slide rail 54 continues to move along the first direction. At the same time, the pushing member 512 is attached to the demoulding member 511, and when the slide rail 54 moves, the pushing member 512 pushes the demoulding member 511 to make the finished product fall off the mold.

[0055] In a specific embodiment, an elastic block 55 is provided between the demoulding structure 51 and the second template 53 .

[0056] Specifically, the elastic part provides certain support and cushioning during the demoulding process through its elastic characteristics, so that the mold can return to its original position more smoothly after demoulding. The elastic part can reduce the vibration and impact of the mold during the demoulding process and protect the mold and the molded product from damage. At the same time, it can ensure that the mold can accurately return to its original position after demoulding, ensuring the continuity and stability of injection molding production.

[0057] Furthermore, during the injection molding process, when the molded product is completed, the demoulding structure 51 starts to push the finished product out of the mold. The elastic member plays a supporting and buffering role at this time, so that the mold can smoothly return to its original position after demoulding. This process ensures that the mold can be quickly prepared for the next round of injection molding production.

[0058] In a specific embodiment, the central axes of the injection head 21, the connecting pipe 22 and the feed hole 52a coincide with each other.

[0059] Specifically, by making the central axes of the injection head 21, the connecting pipe 22 and the feed hole 52a coincide with each other, it is ensured that the path of the plastic particles before entering the injection head 21 is straight, and the plastic particles are prevented from being deflected or blocked during the transportation process. Such a design can ensure that the plastic particles remain smooth and stable during the transportation process inside the injection molding machine, improve the accuracy and stability of the injection molding process, and help ensure the quality and dimensional accuracy of the molded product.

[0060] In a specific embodiment, a cooling block 531 is provided on the second template 53 for absorbing heat.

[0061] Specifically, the cooling block 531 is placed on the second template 53, and its main function is to absorb the heat generated during the injection molding process to reduce the temperature of the mold and promote the rapid cooling of the molded product. This design can effectively control the temperature of the mold, shorten the molding cycle, improve production efficiency, and help avoid deformation or damage of the molded product due to overheating, thereby improving the quality and stability of the product.

[0062] Furthermore, during the injection molding process, when the mold is closed and injection molding begins, the cooling block 531 on the second mold plate 53 begins to absorb the heat released by the heating assembly 30 during the injection molding process. As the cooling block 531 absorbs heat, the temperature of the mold surface gradually decreases, while accelerating the cooling rate of the molded product. Once the molding cycle is completed, the mold opens and releases the molded product.

[0063] The above is only an implementation method of the present application. It should be pointed out that a person skilled in the art can make improvements without departing from the inventive concept of the present application, but these improvements are within the scope of protection of the present application.
