Embodiment 1

[0026] like Figure 1-3 As shown, the present invention provides a technical solution: a high-efficiency injection molding machine, comprising an operation table 1, an injection mechanism 2 is fixedly connected to the upper surface of the operation table 1, and the injection mechanism 2 includes a processing box shell 21, The bottom of the processing box shell 21 is fixedly connected to the upper surface of the operating table 1, the lower surface of the operating table 1 is fixedly connected with a motor box 4, and the outer surface of the processing box shell 21 is slidably connected with a push rod 3 , the outer surface of the push rod 3 penetrates the processing box shell 21 and extends to the inner cavity, and the end of the processing box shell 21 away from the push rod 3 is fixedly connected with a melting box 25 , and the outer surface of the melting box 25 is fixed The raw material barrel 5 is connected, the output end of the melting box 25 is fixedly connected with a...

Embodiment 2

[0031] like Figure 4 As shown, on the basis of the first embodiment, the present invention provides a technical solution: a second ring 644 is fixedly connected to the top of the airbag 61, and the second ring 644 is connected to the first ring through an elastic bending rod 642. Ring 641 active connection.

[0032] The second embodiment has the following working steps:

[0033] Step 1. When the cooling system is activated, the first ring 641 is first separated from the plastic. When the plastic is cooled to the middle, the second ring 644 is separated from the plastic. The first ring 641 and the second ring 644 are separated. It cooperates to achieve layer-by-layer shedding and separation, to achieve the effect of gradually reducing the contact area between the airbag and the plastic, improve the separation efficiency, make the plastic model easier to separate, reduce the plastic adhesion on the outer surfaces of the first ring 641 and the second ring 644, save money resou...

Embodiment 3

[0035] like Figure 5As shown, on the basis of Embodiment 1 and Embodiment 2, the present invention provides a technical solution: a cooling column 24 is fixedly connected to the inner wall of the processing box shell 21, and a cooling column 24 is fixedly connected to the outer surface of the cooling column 24. Condensing mechanism 7, the condensing mechanism 7 includes a cooling groove 75, the cooling groove 75 is fixedly connected to the outer surface of the cooling column 24, and the inner wall of the cooling groove 75 is fixedly connected with a cold runner 71, the cold runner 71 Passing through the cooling tank 75 and extending to the inner cavity, the bottom end of the cold runner 71 is fixedly connected with a condensation pipe 72, and the outer surface of the condensation pipe 72 is fixedly connected with an elastic extension rod 73, and the bottom of the elastic extension rod 73 is fixedly connected A magnetic layer 74 is fixedly connected, and an elastic metal strip...

Abstract

The invention discloses a high-efficiency injection molding machine, and relates to the technical field of injection molding, the high-efficiency injection molding machine comprises an operation table, an injection mechanism is fixedly connected to the upper surface of the operation table, the injection mechanism comprises a treatment box shell, and the bottom of the treatment box shell is fixedly connected to the upper surface of the operation table; and the lower surface of the operation table is fixedly connected with a motor box, the outer surface of the treatment box shell is slidably connected with a push rod, and the outer surface of the push rod penetrates through the treatment box shell and extends into the inner cavity. According to the high-efficiency injection molding machine, molten plastic is injected into the mold through the hot runner, the high-temperature plastic enables gas in the air bag to absorb heat and expand, the first circular ring is driven to move and be connected with the outermost side of the plastic, when a cooling system is started, the gas in the air bag and the plastic are cooled to contract, the first circular ring is firstly separated from the plastic, and the rapid separation effect is achieved; the compression ball and the elastic strip play a buffering role to avoid breakage caused by excessive contraction of the airbag.

Description

technical field [0001] The invention relates to the technical field of injection molding, in particular to a high-efficiency injection molding machine. Background technique [0002] Injection molding machine is the main molding equipment for making thermoplastic or thermosetting plastics into various shapes of plastic products using plastic molding molds. capabilities are widely used in various fields. [0003] When most of the injection molding machines are cooling the model, the plastic shrinks due to the cold, which leads to the problem of inaccurate molding, which increases the workload of manual grinding in the later stage, reduces the work efficiency, and often occurs during the demolding process. SUMMARY OF THE INVENTION [0004] (1) Technical problems solved [0005] In view of the deficiencies of the prior art, the present invention provides a high-efficiency injection molding machine, which solves the problems of inaccurate molding, difficult demolding, or resi...
