Description

Technical Field

[0001] The utility model relates to the technical field of cutting, in particular to a cutting device based on a multi-position glue injection runner. Background Art

[0002] Large plastic products are essential parts in the automobile assembly process. For example, automobile door panels, automobile trim panels, automobile door panel armrest skeletons, etc. are all large plastic products. Due to their product structures and molding characteristics, large plastic products have multiple gates, that is, plastic injection runners, when they are molded and demolded. After the injection molding is completed, the plastic injection runners usually need to be cut off. There are mainly two existing cutting methods: The first method is to cut by manual shaving. Specifically, an operator positions the large plastic product with one hand and tightly holds a cutting tool with the other hand, and sequentially cuts off the plastic injection runners through the cooperation of both hands. This method has a relatively high labor cost and also increases the enterprise management cost. The second method is to cut with a special machine. Specifically, a product is placed on a positioning fixture of the special machine by manual or an injection molding machine manipulator, and then it works through air shearing, punching, laser or other methods to cut off the glue injection runner. The problems with this method are as follows: The special machine is customized according to the product characteristics. Once the characteristics of the large plastic product change, the special machine cannot be adapted to the new product again, and the cost sharing of the special machine equipment is high; in addition, due to machine cutting, when dealing with products with multi-angle and multi-position glue injection runners, it is difficult to ensure the cutting effect of each glue injection runner. Content of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the utility model provides a cutting device based on multi-position injection molding gates. It aims to replace manual labor through the full-automatic operation of a cutting device based on a multi-position glue injection runner, reduce the labor cost, and at the same time be compatible with the cutting of various types of glue injection runners, reducing the hardware cost. Specifically:

[0004] A cutting device based on a multi-position glue injection runner, which includes a frame body. The frame body is formed with a first accommodation cavity and a second accommodation cavity communicating with the first accommodation cavity. A control device, a first driving unit, a second driving unit, a third driving unit and a cutting device matching the control device are arranged in the first accommodation cavity. Under the action of the control device, the first driving unit, the second driving unit and the third driving unit are displaced to complete the positioning of the cutting device.

[0005] Preferably, in the above-mentioned cutting device based on a multi-position glue injection runner, the first driving unit is positioned in the X-axis direction.

The control end of the first driving device is connected to the control device.

[0006] Preferably, for a cutting device based on a multi-position glue injection runner as described above, the second driving unit is positioned in the Y-axis direction. The second driving unit includes a second guide rail perpendicular to the first guide rail and a second driving device arranged on the second guide rail. The control end of the second driving device is connected to the control device.

[0007] Preferably, for a cutting device based on a multi-position glue injection runner as described above, the third driving unit is positioned in the Z-axis direction. The third driving unit includes a third guide rail perpendicular to the first guide rail and the second guide rail respectively, and a third driving device and a fourth driving device arranged on the third guide rail. The control ends of the third driving device and the fourth driving device are connected to the control device.

[0008] Preferably, for a cutting device based on a multi-position glue injection runner as described above, it further includes a positioning device. The positioning device is arranged at the top of the local frame to perform positioning processing on the product to be cut.

[0009] Preferably, for a cutting device based on a multi-position glue injection runner as described above, the second accommodating cavity includes a storage device and a guiding device communicated with the storage device.

[0012] Preferably, for a cutting device based on a multi-position glue injection runner as described above, a locking device is arranged on at least one of the sliding devices.

[0013] Compared with the prior art, the beneficial effects of the present utility model are:

[0014] When the plastic product to be cut is in the state of being located in the first accommodation cavity, the control device receives the control data matching the plastic injection runner input externally. The control device forms a first control instruction for driving the first driving unit, a second control instruction for driving the second driving unit, and a third control instruction for driving the third control unit according to the control data. Under the action of the first control instruction, the first driving unit is displaced to the first position. Under the action of the second control instruction, the second driving unit is displaced to the second position. Under the action of the third control instruction, the third driving unit is displaced to the third position. The positioning points formed by the first position, the second position, and the third position match the externally input control data. That is, at this time, the cutting device is positioned at the plastic injection runner, and the cutting device performs cutting processing on the injection runner. When multiple control data are received, after completing the cutting of the plastic injection runner that matches the current control data, the cutting of the plastic injection runner that matches the next control data can be continued until the shearing of the set plastic injection runner is automatically completed. By adopting a cutting device based on a multi-position injection runner, manual labor is replaced, the labor cost is reduced, and the unmanned operation of gate shearing is realized. The cutting device can move at any position and at any angle following the first driving unit, the second driving unit, and the third driving unit, realizing the versatility of the cutting device and reducing the input cost of the cutting device.

[0019] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the protection scope of the present application.

[0020] As Figures 1 to 3 shown, on the one hand, a cutting device based on a multi-position glue injection runner, which includes a frame body 10. The frame body 10 is formed with a first accommodation cavity 11 and a second accommodation cavity 12 communicating with the first accommodation cavity 11. A control device 13, a first driving unit, a second driving unit, a third driving unit, and a cutting device 72 matching the control device 13 are arranged in the first accommodation cavity 11. Under the action of the control device 13, the first driving unit, the second driving unit, and the third driving unit are displaced to complete the positioning of the cutting device 72.

[0021] The working principle of the above-mentioned cutting device based on a multi-position glue injection runner is as follows: In a three-dimensional space, the specific position of any point can be determined by these three coordinate axes. The present invention determines three coordinates through the first driving unit, the second driving unit, and the third driving unit to realize the position adjustment for determining the cutting position at one time. The position of the cutting position is usually the position where the glue injection runner of a large plastic part is located. For example, if there are three glue injection runners for the current large plastic part, then three cutting position positions are required. For the first plastic glue injection runner, there is a corresponding first cutting position position. Similarly, for the second plastic glue injection runner, there is a corresponding second cutting position position, and for the third plastic glue injection runner, there is a corresponding third cutting position position. The cutting device 72 is respectively positioned at the first cutting position position, the second cutting position position, and the third cutting position position to complete the cutting of the third plastic glue injection runner.

[0022] Specifically, when the plastic product to be cut is in the state located in the first accommodating cavity 11, the control device 13 receives the control data matching the plastic injection runner input externally. The control device 13 forms a first control instruction for driving the first driving unit, a second control instruction for driving the second driving unit, and a third control instruction for driving the third control unit according to the control data. Under the action of the first control instruction, the first driving unit is displaced to the first position. Under the action of the second control instruction, the second driving unit is displaced to the second position. Under the action of the third control instruction, the third driving unit is displaced to the third position. The positioning points formed by the first position, the second position, and the third position match the control data input externally. That is, at this time, the cutting device 72 is positioned at the plastic injection runner, and the cutting device 72 performs a cutting process on the injection runner. When multiple control data are received, after completing the cutting of the plastic injection runner that matches the current control data, the cutting of the plastic injection runner that matches the next control data can be continued until the shearing of the set plastic injection runner is automatically completed.

[0023] A cutting device based on a multi-position injection runner is adopted, replacing manual labor, reducing labor costs, and realizing unmanned shearing of the sprue. The cutting device 72 can move to any position and at any angle following the first driving unit, the second driving unit, and the third driving unit, realizing the versatility of the cutting device 72 and reducing the input cost of the cutting device 72.

[0024] As a further preferred implementation scheme, for the above-mentioned cutting device based on a multi-position injection runner, the first driving unit is positioned in the X-axis direction. The first driving unit includes a first guide rail 41 arranged on the frame body 10 and a first driving device (built into the first guide rail 41 and not marked in the figure) arranged on the first guide rail 41. The control end of the first driving device is connected to the control device 13. As a further preferred implementation scheme, in order to further improve the stability of the movement in the X-axis direction, the above technical solution further includes a first auxiliary guide rail 42. The first guide rail 41 and the first auxiliary guide rail 42 are arranged in parallel at both ends of the frame body 10.

[0025] As a further preferred implementation scheme, for the above-mentioned cutting device based on a multi-position injection runner, the second driving unit is positioned in the Y-axis direction. The second driving unit includes a second guide rail 51 perpendicular to the first guide rail 41 and a second driving device arranged on the second guide rail 51. The control end of the second driving device is connected to the control device 13. Further, the second guide rail 51 is perpendicular to the first auxiliary guide rail 42 at the same time.

[0026] As a further preferred embodiment, in the above-mentioned cutting device based on a multi-position glue injection runner, the third driving unit is positioned in the Z-axis direction. The third driving unit includes a third guide rail 61 perpendicular to the first guide rail 41 and the second guide rail 51 respectively, and a third driving device and a fourth driving device 71 arranged on the third guide rail 61. The control ends of the third driving device and the fourth driving device 71 are connected to the control device 13. It should be noted that the fourth driving device 71 is actually an R-axis rotation driving device, and the R-axis driving device rotates around the Z-axis.

[0027] During operation, after a plastic product to be cut is placed at a predetermined position by a manipulator or other means, the equipment starts. The first driving device, the second driving device, the third driving device, and the fourth driving device 71 automatically reach the designated positions according to the set control data, and then the cutting device 72 starts to cut off the plastic glue injection runner at this position. Then, the first driving device, the second driving device, the third driving device, and the fourth driving device 71 cooperate with each other to automatically move to the next coordinate to cut off the sprue, and so on until the shearing of the set plastic glue injection runner positions is automatically completed.

[0028] It should be noted that: the control device 13 may include a human-machine interaction interface, which receives externally input control data through the human-machine interaction interface. The first driving device, the second driving device, the third driving device, the fourth driving device 71, and the cutting device 72 are all controlled by a programmable controller, and monitoring and visualization operations are realized through the human-machine interaction interface. Those skilled in the art can implement the above technical solutions through the prior art, and the present invention will not be further described.

The positioning device 8 is arranged at the top of the local part of the frame to perform positioning processing on the product to be cut. Further, it further includes a mounting base plate 9. The positioning device 8 is arranged on the mounting base plate 9. Different product positioning devices 8 can be installed on this mounting plate, and the versatility of the tooling can be realized only by replacing the positioning device 8 when producing different products.

The opening direction of the guiding device faces the first accommodating cavity 11, and the guiding device 82 is in a funnel shape. After the glue injection runner is sheared, the residual items of the glue injection runner enter the storage device along the funnel.

[0031] It should be noted that the connection between the control device and the first driving device, the second driving device, the third driving device, and the fourth driving device can be realized by a wireless connection method, and the purpose of the connection is for data transmission.
