Description

Technical Field

[0001] The utility model relates to injection molding production equipment, in particular to a mold material head cutting machine. Background Art

There is an existing injection molding product whose gate material is cross-shaped, and a product is arranged at each of the four ends of the cross-shaped gate material. Before the product is produced and processed, the product needs to be cut off from the gate material. The existing product cutting requires manual use of a cutting knife to cut the product off from the casting material one by one, so the work efficiency is low, it requires more manpower, and there are certain safety issues.

[0037] Reference below Figure 1-5 Describe the utility model;

[0038] Mould stub cutting machine, including:

[0039] The frame 100 has a fixed support base 110 on the top;

[0040] The connecting arm 200 is hinged in the middle on the support seat 110, and a linear driving mechanism 300 is provided at the tail end to drive the connecting arm 200 to rotate; a reset spring 400 connected to the support seat 110 is provided at the tail end of the connecting arm 200, and after the stamping is completed, the connecting arm 200 is restored to the original state to be cut off through the reset spring 400; the bottoms of both ends of the connecting arm 200 of this case are respectively in an arc-shaped structure, which improves the stability and reliability of lifting or pressing down;

[0041] The pressing rod 500 is slidably disposed on the support seat 110 through an oil-free bushing and is located below the head end of the connecting arm 200;

[0042] The knife holder plate 600 is hinged or fixedly connected to the pressing rod 500 at the top and is provided with a detachably fixed nylon knife pad 610 at the bottom;

[0043] The lower cutting knife 700 is fixedly arranged below the nylon knife pad block 610 , and a material transfer spacing is provided between the lower cutting knife 700 and the nylon knife pad block 610 .

[0044] The above-mentioned linear drive mechanism 300 includes a gas-liquid booster cylinder or an electric push rod; an adjustment rod adapted to the linear drive mechanism 300 is provided on the support seat 110; the adjustment rod is slidably arranged on the support seat 110, and a sleeve hole adapted to the piston rod of the linear drive mechanism 300 is provided at the bottom.

[0045] In this case, the adjusting rod is limitedly arranged in the support seat 110. When the piston rod rises to a certain height, it is inserted into the sleeve hole at the bottom of the adjusting rod. A fixedly connected sensor plate is provided at the bottom of the adjusting rod for installing corresponding sensors, such as a height sensor.

[0046] In this case, a gas-liquid booster cylinder is preferably used, which is fixedly arranged in the frame 100; the piston rod of the gas-liquid booster cylinder extends upward, driving the adjustment rod connected by sliding up and down to move upward, and pushing the tail end of the connecting arm 200 upward; thereby, the head end of the connecting arm 200 presses the pressing rod 500 downward, and then the nylon pad knife block 610 presses the gate material downward to separate it from the product. The remaining gate material is rotated by the robot and waits for the next product to be cut.

[0047] The structure of the knife edge support 710 is further optimized:

[0048] The blade of the lower cutter 700 faces upwards and is fixedly arranged below the nylon pad knife block 610 through a blade support 710. In this case, the lower cutter 700 is detachably fixedly arranged on the blade support 710 through a connecting piece, and the blade support 710 is fixedly connected to the frame 100.

[0049] On the blade support 710, a limit seat 720 is provided on the side of the lower cutting knife 700 and is adjustable and fixedly connected up and down.

[0050] The limiting seat 720 is an L-shaped structure, including a supporting portion 721 and a knife limiting portion 722 connected in sequence;

[0051] The support portion 721 is vertically arranged and is provided with a support groove adapted to the gate material for supporting the gate material;

[0052] The knife limiting portion 722 is in the shape of a plate and is located below the cutting edge of the cutting knife to protect the cutting edge.

[0053] The gate material on the blade is pressed down by the nylon pad knife block 610, so that the gate material is cut off by the blade. When it is completely cut off, the bottom surface of the nylon pad knife block 610 contacts the top surface of the knife limiter 722, preventing the nylon pad knife block 610 from continuing to press down, thereby increasing the service life of the blade. At the same time, the existing sensor technology can also be used to control the downward stroke of the nylon pad knife block 610.

[0054] The structure of nylon knife block 610 is further optimized:

[0055] The bottom of the nylon knife pad 610 is provided with a knife groove adapted to the blade of the lower cutting knife 700 .

[0056] A support block 620 is provided between the nylon knife pad block 610 and the knife holder plate 600;

[0057] The top of the support block 620 is detachably fixedly connected to the tool holder plate 600 , and the bottom is detachably fixedly connected to the nylon knife pad block 610 .

[0058] The structure of the tool holder plate 600 is further defined as follows:

[0059] The tool holder plate 600 is in an L-shaped structure;

[0060] The side of the tool holder plate 600 is connected to the side of the support seat 110 by sliding up and down through the guide rail.

[0061] It is further defined that in this case, a fixedly connected slide plate is provided on the side of the tool holder plate 600, and a vertically arranged guide rail is fixedly connected to the side of the support seat 110, and the tool holder plate 600 and the support seat 110 are connected by sliding up and down through a slider.
