Description

Technical Field

[0001] This utility model relates to the field of cutting equipment technology, specifically to a dual-station syringe gate cutting device. Background Technology

[0002] The high-pressure contrast injection syringe uses a dual-station injection mold, which can simultaneously injection mold two syringe barrels. Two connected syringe barrels can be injection molded at the same time through the gate. The gate is a key component of the injection mold, which connects the runner and the cavity, allowing the molten plastic from the syringe barrel to enter the cavity.

[0003] The injection molding machine feeds thermoplastic or thermosetting plastic into a dual-station injection mold through a gate. When the syringe barrel is formed in the mold, the thermoplastic or thermosetting plastic at the gate also solidifies and connects with the syringe barrel. In order to obtain a single syringe barrel, an automatic gate cutting device is needed to cut off the gate.

[0004] For example, Chinese patent CN220447066U discloses an automatic gate cutting device, including a frame, an automatic gate cutting mechanism, and a feeding mechanism. The feeding mechanism includes a support plate, a horizontal moving module, a horizontal moving module, a placement plate, and a guiding assembly. One end of the support plate extends to the outside of the frame. The horizontal moving module is mounted on the support plate, and its output end is connected to the vertical moving plate. The horizontal moving module is mounted on the vertical moving plate, and its output end is connected to the horizontal moving plate. The placement plate is mounted on the horizontal moving plate, and its top has a placement groove. The guiding assembly is used to guide the plastic products discharged from the automatic gate cutting mechanism into the placement groove.

[0005] However, the device cannot be used with two high-pressure contrast injection syringes connected together, and cannot quickly and effectively remove the gate.

[0006] Based on this, the present invention designs a dual-station injector gate cutting device to solve the above problems. Utility Model Content

[0058] In use, the present invention places two injection-molded and connected contrast injection syringes into the first clamping port 222 and the second clamping port 223 through the feeding assembly. The output end of the cylinder 213 drives the triangular cone 215 to move upward. The triangular cone 215 contacts the inclined surfaces 225 on the left and right sides respectively, and pushes the sliding rods 224 on both sides to move outward through the inclined surfaces 225. The sliding rods 224 drive the clamping plate 227 to clamp and fix the two contrast injection syringes.

[0059] At this time, the first pneumatic slide 211 starts to drive the support plate 212 and the cylinder 213 to move, so that the fixed seat 221 drives the two contrast injection syringes to move to the resection position;
