Description

Technical Field

[0001] The utility model relates to the field of automated production, and in particular to an inner-type plastic part gate processing device. Background Art

[0002] The gate refers to the last door through which the molten plastic enters the cavity through the pouring system. It is the feed channel connecting the runner and the cavity. It has two functions: first, it controls the flow of the plastic melt into the cavity; second, when the injection pressure is withdrawn, it seals the cavity so that the plastic that has not yet cooled and solidified in the cavity will not flow back. At present, the gate of most products is formed on the external side of the product, and the corresponding gate cutting equipment is also designed for the gate formed on the external side of the product. For example, the existing patent, patent number: CN219213966U, is named: an automatic punching gate device, which uses a horizontally moving cutter to cut off the gate left on the external side of the product. This method cannot cut off the gate designed to be more hidden on the inside of the product, such as Figure 1 The gate of the bottle cap shown is designed on the inside of the handle, and the bottle cap cannot be positioned upside down to meet the alignment of the cutter. Obviously, the existing automatic gate cutting device is unable to achieve the gate cutting of the bottle cap. In addition, the existing automatic gate cutting device will turn white at the cutting position after cutting the gate, which requires manual processing, resulting in low production efficiency. Utility Model Content

[0005] Furthermore, the cylinder assembly includes a first cylinder and a second cylinder, the piston rod of the first cylinder is provided with a movable frame, the second cylinder is installed on the movable frame, and the pressing knife is installed on the piston rod of the second cylinder.

[0006] Furthermore, a pressing block and a plurality of pressing columns are further arranged at the bottom of the movable frame.

[0032] Reference Figure 3-4 As shown, the utility model discloses an inside type plastic part gate processing equipment, including a base 10, on which a moving module 30 and a pressing module 20 are installed; the moving module 30 is used to move the injection molded bottle cap 40 to the bottom of the pressing module 20, and the pressing module 20 is used to press down to remove the residual gate 401, replacing manual operation to realize automatic removal of the material gate.

[0033] Reference Figure 3-8As shown, the moving module 30 includes a moving track 301, and a positioning fixture is arranged on the moving track 301; the positioning fixture includes a tray 302, and two positioning blocks 303 are arranged on the tray 302, and the positioning blocks 303 have a positioning groove 3031, and a through hole 3032 is arranged at the bottom of the positioning groove 3031. The tray 302 is arranged between the two moving tracks 301 through a slider, and the tray 302 has a strip hole along the length direction. The two positioning blocks 303 are placed on the tray 302, and the two sides are fixed by blocks. The bottle cap 40 is placed in the positioning groove 3031, and the bottle cap 40 is placed in the positioning groove 3031 and moved to the bottom of the pressing module 20 through the moving track 301 to realize the rapid positioning of the bottle cap 40. Further, a pressure strip 304 is arranged on one side of the positioning groove 3031 on the tray 302, and the pressure strip 304 plays the role of pressing and fixing the positioning block 303.

[0034] Reference Figure 3-8 As shown, the pressing module 20 includes a bracket 201, on which a cylinder assembly and a pressing knife 2031 are installed. An installation groove is provided at the upper end of the pressing knife 2031, and a heating rod (not shown in the figure) is arranged in the installation groove. The cylinder assembly drives the pressing knife 2031 to press down and approach the positioning fixture. Specifically, the cylinder assembly includes a first cylinder 202 and a second cylinder 203. The piston rod of the first cylinder 202 is provided with a moving frame 204, the second cylinder 203 is installed on the moving frame 204, the pressing knife 2031 is installed on the piston rod of the second cylinder 203, and the heating rod heats the pressing knife.
