Detailed Description
The present invention will be described in further detail below.
As shown in fig. 1 to 4, the slag cutting device of the injection molding machine for cutting polydicyclopentadiene material between the injection sleeve 5 and the injection gate 63 comprises a frame 61, a driving device, a cutter 1 and a control device, wherein the cutter 1 is arranged at one side of the injection sleeve 5 and is opposite to one end of the injection sleeve 5, the driving device is fixedly connected to the frame 61 and drives the cutter 1 to move towards one end of the injection sleeve 5, and the control device controls the driving device to operate. Because the cutterbar 1 locates injection cover 5 one side and sets up with injection cover 5 one end is relative, when drive arrangement drive cutterbar 1 moved towards injection cover 5, cutterbar 1 can cut off the residue between injection cover 5 and the injection runner 63 fast, and cutting speed is fast, convenient to use, and the cost of labor is low.
The cutter 1 comprises a cutter body 12 and a cutter seat 11, the cutter body 12 is fixedly connected with the cutter seat 11, the cutter body 12 is provided with a through hole 121, two ends of the through hole 121 are respectively abutted against the injection sleeve 5 and the injection gate 63, so that a channel between the injection sleeve 5 and the injection gate 63 is communicated, and injection materials enter the mold frame 62 through the injection sleeve 5, the through hole 121 and the injection gate 63; the edge of the through hole 121 is provided with a blade 122, and when the cutter 1 performs a cutting action, the driving device drives the blade body 12 and the blade holder 11 to move, so that the two ends of the through hole 121 are respectively staggered with the injection sleeve 5 and the injection gate 63, and the blade 122 rapidly cuts the material between the injection sleeve 5 and the injection gate 63.
The injected material, once cured, becomes very hard and difficult to cut, and therefore it is desirable to cut as quickly as possible before it cures. The through hole 121 is arranged between the injection sleeve 5 and the injection gate 63, the distance between the material in the injection sleeve 5 and the blade 122 is zero, the material in the injection sleeve 5 can be cut off most quickly when the blade 122 moves, and the use is convenient and quick.
The provision of the cutting edge 122 in the body 12 with the through-hole 121 defined by the cutting edge 122 aligned with the injection sleeve 52 and the injection gate 63 provides two benefits: when material injection is required, the injected material can pass through the through hole 121 into the injection gate 63, so that the blade body 12 becomes a part of an injection passage from the injection sleeve 5 to the injection gate 63; the cutting edge 122 can cut the material at the injection gate 63 with the shortest stroke when cutting is required.
The thickness of the tool apron 11 is larger than that of the tool body 12. The thicker blade seat 11 makes the base of the cutter 1 stronger and more durable, and the thinner blade body 12 makes the cutting action lighter.
The inclined plane 13 is arranged at the joint of the cutter holder 11 and the cutter body 12, and when the cutter is used for cutting, the inclined plane 13 is in contact with the injection sleeve 5, so that the impact damage of the cutter holder 11 to the injection sleeve 5 can be reduced as much as possible.
The driving device comprises a cylinder 13, a cylinder barrel of the cylinder 13 is fixedly connected to the frame 61, and an ejector rod of the cylinder 13 is fixedly connected with the tool apron 11.
The two sides of the cutter 1 are respectively provided with a first guiding device and a second guiding device which are used for guiding the movement of the cutter 1, and the first guiding device and the second guiding device are respectively fixedly connected with the frame 61. Through the guidance of the first guiding device and the second guiding device, the movement of the cutter 1 towards the injection sleeve 5 is more accurate and smoother.
The tool apron 11 is fixedly connected with a tool apron fixing block 3, the first guiding device and the second guiding device are respectively a first positioning plate and a second positioning plate, and the first positioning plate and the second positioning plate are respectively connected with the tool apron fixing block 3 in a sliding mode. Because first locating plate and second locating plate surface are the plane, blade holder fixed block 3 and first locating plate and second locating plate area of contact each other is great, and the direction is more reliable for the slip of blade holder 11 is more steady, is favorable to the accurate cutting of cutting edge 122.
A fixed block pressing plate 4 is slidably connected above the cutter holder fixed block 3, and the fixed block pressing plate 4 is fixedly connected to the frame 61. There are two benefits to using this configuration: 1. the outer surface of the fixed block pressing plate 4 is a plane, the contact area between the cutter holder fixed block 3 and the fixed block pressing plate 4 is large, and the fixed block pressing plate 4 plays a good cutting guiding role, so that the cutter holder 11 slides more stably, and accurate cutting of the cutting edge 122 is facilitated; 2. the fixed block pressing plate 4 protects the knife holder 11 and the knife body 12, and an operator cannot contact the knife body 12 in the operation process, so that the knife edge 122 can be prevented from being injured, and the cutting process of the knife edge 122 is safer.
The working principle of the invention is as follows:
when the injection sleeve is in work, one cavity of the air cylinder 13 is inflated, the other cavity of the air cylinder is exhausted, the ejector rod of the air cylinder 13 is pushed out, the cutter holder 11 and the cutter body 12 are driven to move forwards, the through hole 121 of the cutter body 12 is staggered with the hole of the injection sleeve 5 and is not aligned any more, and the cutting edge 122 cuts off materials in the injection sleeve 5.
The above embodiments are preferred embodiments of the present invention, but the embodiments of the present invention are not limited to the above embodiments, and any other changes, modifications, substitutions, combinations, and simplifications which do not depart from the spirit and principle of the present invention should be equivalent replacement modes, and all are included in the scope of the present invention.
