Problems solved by technology

Its disadvantage is that the one-time injection volume cannot be too large, and when the screw is retreating, its effective thread is reduced and the plasticizing quality is affected.
However, the injection group and the injection rod of the invention are easy to accumulate material and are not easy to remove
This technical defect widely exists in all kinds of existing plastic injection molding machines

Embodiment 1

[0038] Such as figure 1 , Figure 9 with Figure 10 A plastic extrusion molding machine with material cleaning function is shown, including an injection component and a plasticizing component, the injection component and the plasticizing component are connected through an injection connecting rod 2, and the plasticizing component includes a plasticizing screw 1-2, a pre-plasticizing The front feed barrel 1-3 and the plasticizing feed barrel 1-1, the pre-plastic front feed barrel is provided with a feed passage 16 communicating with the injection rod 2 (see Figure 10 ), the feeding channel is L-shaped, the central axis of the vertical section of the feeding channel and the central axis of the injection rod are on a straight line, and the horizontal section of the feeding channel 16 communicates with the inner cavity of the plasticizing barrel 1-1 , and the end of the horizontal section of the feeding channel 16 connected to the plasticizing barrel 1-1 is a bell mouth. The i...

Embodiment 2

[0045] A kind of plastic injection molding machine, it except having all structures described in embodiment 1, also has a figure 2 , image 3 , Figure 5 , Image 6 with Figure 7 As shown, the main body 7-1 of the injection plunger is a cylinder, which has a conical injection head 7-3, and a cleaning step 7-2 is set between the injection head and the main body, and the cleaning step is formed by the second cylinder 7 -4 is connected with the second circular platform 7-5, the other end of the second cylinder is connected with the bottom of the circular platform of the injection head, and the other end of the second circular platform is connected with the main body. The pre-injection barrel has a cavity wall that matches the injection head of the injection plunger and the outer contour of the purge step (see Figure 4 ).

[0046] The injection head, the cleaning step and the main body are rotating bodies with the same axis. The main body of the injection plunger is provi...

Abstract

The invention relates to a plastic molding machine, and particularly relates to a plastic extrusion injection molding machine with an injection connecting rod defective material cleaning function. The plastic extrusion injection molding machine with the injection connecting rod defective material cleaning function comprises an injection component and a plasticizing component which are connected by an injection connecting rod; the plasticizing component comprises a plasticizing screw rod, a pre-plasticizing front charging barrel and a plasticizing charging barrel; a cleaning component is fixed above the pre-plasticizing front charging barrel, and comprises a cleaning oil cylinder and a cleaning plunger; the cleaning oil cylinder is internally provided with a piston rod; the cleaning plunger is installed at one end of the piston rod, and the other end of the piston rod is sleeved by a seal ring so that a piston head is formed at the end part of the piston rod; the piston rod drives the cleaning plunger to move in a reciprocating mode along the inner cavity of the pre-plasticizing front charging barrel and the inner cavity of the injection connecting rod. In order to remove defective materials out of the injection connecting rod, the invention designs a special cleaning oil cylinder and the cleaning plunger with a cleaning groove in the head part.

Description

technical field [0001] The invention relates to a plastic molding machine, in particular to a plastic extrusion molding machine with the function of cleaning the residual material of the injection rod. Background technique [0002] The plastic extrusion molding machine is a new type of plastic injection molding machine. The traditional plastic injection molding machine has only one screw, which not only plays the role of material storage, but also plays the role of injection. Its disadvantage is that the one-time injection volume cannot be too large, and when the screw is retreating, its effective thread is reduced and the plasticizing quality is affected. At present, the domestically produced single-screw reciprocating plastic injection molding machine with a clamping force of 40,000KN has a one-time theoretical injection volume of 62,000cm 3 . The TRX-J plastic injection molding machine manufactured by Terry Machinery Co., Ltd. has a clamping force of 40,000KN, and its o...
