Description

Technical Field

[0001] The utility model belongs to the technical field of injection molding machines, and particularly relates to a rapid injection molding mechanism of an injection molding machine. Background Art

[0002] Injection molding machine is also called injection molding machine or injection machine. It is the main molding equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastics or thermosetting plastics. It is divided into vertical, horizontal and all-electric types. The injection molding machine can heat the plastic and apply high pressure to the molten plastic to make it ejected and fill the mold cavity.

[0003] The existing injection molding machine generally includes an injection molding cylinder, an injection molding rod, a heating plate and a feeding cylinder. The raw material enters the injection molding cylinder through the feeding cylinder, and then is heated and melted by the heating plate. The melted raw material is injected into the mold through the injection molding rod for molding.

[0004] However, the raw materials are fed into the injection molding cylinder through the feeding cylinder. These raw materials are in granular form and it takes a certain amount of time for them to melt when they enter the injection molding cylinder. This slows down the injection molding speed. At the same time, the heating plate keeps releasing heat when heating. This heat cannot be utilized and dissipates in the air, resulting in energy waste.

[0005] Therefore, we propose a rapid injection molding mechanism for an injection molding machine, which can not only pre-treat and heat the raw materials and perform rapid injection molding, but also utilize the heat to achieve the effect of saving energy. Utility Model Content

[0006] The utility model aims to provide a rapid injection molding mechanism of an injection molding machine, which can not only pre-treat and heat the raw materials and perform rapid injection molding, but also utilize the heat to achieve the effect of saving energy.

[0023] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.

[0024] like Figure 1-4 As shown, the technical solution adopted in the present invention is specifically as follows: a rapid injection molding mechanism of an injection molding machine, including a fixed plate 1, an injection molding machine body 2 is arranged on the fixed plate 1, a motor 3 is installed at one end of the injection molding machine body 2, and a plurality of heating plates 4 are arranged on the injection molding machine body 2, and the heating plate 4 is a ceramic cast aluminum electric heating plate 4, which has high heat resistance and insulation performance, fast heating speed, good temperature uniformity, and long service life, belongs to the prior art, and no excessive elaboration is made here.

[0025] A connecting rod 5 is provided on the injection molding machine body 2, and a heat absorption tube 6 in contact with multiple heating plates 4 is installed on the top of the connecting rod 5. A feeding cylinder 7 connected with the heat absorption tube 6 is provided on the top, and a material guiding assembly is provided inside the heat absorption tube 6. A material guiding pipe 8 is installed at the bottom of the heat absorption tube 6, and the bottom of the material guiding pipe 8 is connected with the injection molding machine body 2.

[0026] The above working principle is: when working, multiple groups of heating plates 4 work to generate heat to melt the raw materials inside the injection molding machine body 2 for injection molding. At the same time, the heat generated by the heating plates 4 will also be absorbed by the heat absorbing tube 6, so that the inside of the heat absorbing tube 6 has heat, and the raw materials enter the heating tube through the feeding tube 7, and the raw materials are preheated by the heat inside the heating tube. The pretreated raw materials enter the material guide pipe 8 through the material guide assembly, and then enter the injection molding machine body 2 through the material guide pipe 8, so that there is no need for too much time to melt, thereby improving the purpose of rapid injection molding, and at the same time, the energy of the heating plate 4 can be utilized, thereby achieving the effect of saving energy.

[0027] Among them, for the material of the heat absorption tube 6, materials with good heat resistance and thermal conductivity are generally selected to ensure that heat can be effectively absorbed and transferred. Common outer materials of the heat absorption tube 6 include metal materials such as stainless steel, aluminum alloy and copper. These materials have good heat resistance and thermal conductivity and can meet the requirements of high temperature and high heat flux density.

[0028] At the same time, in order to prevent the heat absorbing tube 6 from escaping quickly when absorbing heat, Figure 2 As shown, a protective sealing shell 9 can be provided outside the injection molding machine body 2 and the heat absorbing tube 6, so as to reduce the heat dissipation.

[0029] In this embodiment, Figure 4 As shown, the heating plate 4 is fitted with the heat absorbing tube 6 to absorb heat. In order to ensure that more heat is absorbed and the heat absorbing area is increased, a plurality of groups of heat absorbing fins 10 can be arranged on the heat absorbing tube 6. The material of the heat absorbing fins 10 is the same as that of the heat absorbing tube 6. This can increase the heat absorbing area and improve the effect of pretreatment.

[0030] like Figure 2 and Figure 3 As shown, the material guiding assembly includes a first rotating shaft 11 rotatably arranged inside the heat absorbing tube 6, and a first spiral toothed disk 12 is arranged on the first rotating shaft 11. The first spiral toothed disk 12 can guide the incoming raw material. One end of the first rotating shaft 11 passes through the heat absorbing tube 6, and a first rotating disk 13 is sleeved on the penetrating portion of the first rotating shaft 11. The outer side of the first rotating disk 13 is connected to a second rotating disk 15 sleeved on the output end of the motor 3 through a transmission belt 14. The transmission belt 14 is driven by the motor 3 to rotate the first rotating disk 13. The first rotating disk 13 drives the first spiral toothed disk 12 to move the raw material entering through the feed cylinder 7 to the position of the material guiding tube 8, so that the raw material enters the injection molding machine body 2 through the material guiding tube 8.

[0031] At the same time, after the heat absorbing tube 6 absorbs heat, there is a certain amount of heat inside the heat absorbing tube 6. When the first spiral toothed disk 12 drives the raw material to move, it can not only melt the raw material for pretreatment, but also make the heat even, thereby improving the effect of the pretreatment.

[0032] It should be noted that the raw material is easy to adhere to the inner wall of the cylinder after melting, and an anti-adhesion coating can be provided inside the heat absorbing cylinder 6. This coating is polytetrafluoroethylene, which has a very low surface energy and is often used to make non-stick pans and other items. It can be applied to the barrel wall to prevent the plastic from melting and sticking to the inner wall of the cylinder.

[0033] like Figure 3 As shown, the injection molding machine body 2 includes an injection molding cylinder 18 and an injection molding rod 16 arranged inside the cylinder. One end of the injection molding rod 16 passes through the injection molding cylinder 18 and is connected to the motor 3. A cylinder 17 is arranged at the non-output end of the motor 3. The injection molding rod 16 is driven to rotate by the motor 3, and the injection molding rod 16 is driven to move by the cylinder 17, thereby performing injection molding.

[0034] Among them, three support seats are arranged on the top of the fixing plate 1, and the three support seats support the injection molding machine body 2, the motor 3 and the cylinder 17 respectively.

[0035] The working principle of the utility model is as follows: first, when working, multiple groups of heating plates 4 work, thereby generating heat to melt the raw materials inside the injection molding machine body 2 for injection molding, and at the same time, the heat generated by the heating plate 4 will also be absorbed by the heat absorbing tube 6, so that the heat absorbing tube 6 has heat inside, and the raw materials enter the heating tube through the feeding cylinder 7, and the raw materials are preheated by the heat inside the heating tube. The pretreated raw materials drive the conveyor belt 14 through the motor 3 to rotate the first rotating disk 13, and the first rotating disk 13 drives the first spiral toothed disk 12 to move the raw materials entering through the feeding cylinder 7 to the position of the guide tube 8, so that the raw materials enter the injection molding machine body 2 through the guide tube 8. The guide tube 8 enters the injection molding machine body 2, so that it does not need too much time to melt, thereby improving the purpose of rapid injection molding, and at the same time, the heating plate 4 can be utilized to achieve the effect of saving energy. The device can not only pre-treat and heat the raw materials, can perform rapid injection molding, but also can utilize heat to achieve the effect of saving energy.

[0036] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
