Embodiment 1

[0025] see figure 2 , this embodiment includes a frame 13, a mechanical transmission mechanism I and a pressurization mechanism II, and the mechanical transmission mechanism I, the pressurization mechanism II and the mold 11 are connected in series.

[0026] The mechanical transmission mechanism I is a toggle link mechanism, which is composed of a slider 10, a connecting rod structure I-1, and a pedal rod 1, wherein the connecting rod structure I-1 includes a cross bar 9, a straight bar 8, and a pull bar 7 , upper connecting rod 4-2, lower connecting rod 4-1, pressurizing mechanism II is hydraulic mechanism, is made up of main oil cylinder 5, auxiliary oil cylinder 2, spring 3, connecting rod 14, wherein main oil cylinder 5 is fixed on the frame 13 , the mold 11 is fixed below the slide block 10, one end of the cross bar 9 is connected with the slide block, and the other end is movably connected with the straight bar 8, the upper connecting rod 4-2, the lower connecting rod 4...

Embodiment 2

[0029] The difference between the present embodiment and embodiment 1 is that the position of the auxiliary oil cylinder 2 is as shown in Figure 5, that is, between the mechanical transmission mechanism 1 and the auxiliary oil cylinder 2, connecting rods 15, 16 are added; its method of use is the same as in embodiment 1, The state after stepping on the pedal lever 1 is as follows Figure 6 As shown, due to the increase of the connecting rods 15 and 16, when the pressurization stroke is completed, the reaction force of the auxiliary oil cylinder 2 acting on the pedal rod 1 can be reduced, increasing the comfort of operation.

Embodiment 3

[0031] Referring to Fig. 7, the difference between this embodiment and Embodiment 1 is that the main oil cylinder 5 is connected with the oil pump 22, that is, the main oil cylinder 5 is supplied with oil by the oil pump 22, and the shaft of the pedal rod 1 directly passes through the connecting rod 14 and the lower connecting rod. 4-1 is connected to the junction of the upper connecting rod 4-2, and the auxiliary cylinder 2 and the spring 3 are omitted; -2 and the lower connecting rod 4-1 extend to the self-locking position to complete the mold clamping stroke, then connect the oil pump 22, and the main oil cylinder 5 is supplied with oil by the oil pump 22 to generate a thrust to act on the workpiece 12 to complete the pressurization stroke.

[0032] The master cylinder 5 in this embodiment can also be supplied with oil by devices such as a hydraulic station.

Abstract

The invention discloses a pressure apparatus, especially for a kind of block press and the method for pressuring it, which is applied mainly to pressure workpiece on plastic block press. Said pressure apparatus of the block press comprises holster, positioned a pressure device for pressure stroke and a mechanical drive gear for shutoff stroke and transmitting repulsion, which is made by pressure device, wherein said two devices is connected in the form of cascade. The method for pressuring comprises the following steps: first positing the workpiece needed to be handling under the mold, then performing shutoff stroke by the mechanical drive gear, forcing it by the pressure device, and transmitting said force to mold by the mechanical drive gear, and the mold forcing the workpiece in turn, to finish the pressure stroke. The invention is provided with the advantages of saving labor, fine effect, high efficiency, and low energy consumption.

Description

technical field [0001] The invention relates to a pressurizing device, in particular to a pressurizing device of a molding press and a pressurizing method thereof, which are mainly used for pressurizing workpieces of a plastic molding press. Background technique [0002] The working process of the molding press can be divided into the mold clamping (or mold counter) process and the pressurization process according to the required thrust. The stroke of the mold clamping process is large and the thrust is small, and its stroke accounts for more than 90% of the total stroke. Small and powerful. The existing workpiece pressurizing device only uses mechanical transmission mechanism for mold clamping and pressurization. Due to the limitation of space and mechanism, it is difficult to achieve the best labor-saving effect, and it is very laborious to use. [0003] Some workpiece pressurization devices only use electro-hydraulic devices to provide the pressure required for mold clam...
