Description

Technical Field

[0001] The utility model relates to the technical field of deburring injection molded parts, in particular to a feeding device for processing injection molded parts. Background Art

[0002] Cylindrical parts formed by injection molding generally require secondary finishing, grinding and polishing the cylindrical outer surface of the parts to remove surface burrs, etc., so that the product becomes the final product. In the deburring and grinding operation of small cylindrical injection molded workpieces with small volume and light weight, the existing feeding device for injection molded parts processing needs to clamp and fix the parts first, and then send them to the grinding processing center to grind the cylindrical surface by rotating the mold or the parts. This method is too cumbersome and is not practical for processing small and medium-sized lightweight cylindrical injection molded parts. Based on this, a feeding device for injection molded parts processing is proposed. Utility Model Content

[0003] In order to solve the technical problem of deburring injection molded parts, the utility model provides a feeding device for injection molded parts processing.

[0004] The utility model is implemented by the following technical solutions: a feeding device for processing injection molded parts, comprising a rotating drum, a plurality of gripping handles, a plurality of clamping blocks and a plurality of support plates, the upper side of the rotating drum being rotatably connected to the lower ends of the plurality of gripping handles, the plurality of gripping handles being distributed in a circular array, the upper ends of the plurality of gripping handles being fixedly connected to the lower sides of the support plates, the upper sides of the plurality of support plates being fixedly connected to the clamping blocks, a sleeve limiting mechanism for limiting and fixing the rotating drum is provided on the lower side of the rotating drum, and a clamping rod driving mechanism for bringing the plurality of gripping handles close to each other, gripping them and rotating them is provided on the inner side of the rotating drum.

[0005] As a further improvement of the above scheme, the sleeve limiting mechanism includes a mounting cylinder and a limiting sleeve. The upper side of the mounting cylinder is fixedly connected to the upper side of the limiting sleeve, the inner side of the limiting sleeve is rotatably connected to the outer side of the rotating cylinder, and the lower side of the mounting cylinder is provided with a cylinder lifting and lowering mechanism for raising or lowering the mounting cylinder.

[0006] As a further improvement of the above scheme, the clamping rod driving mechanism includes a No. 2 oil cylinder, a connecting rod, a slide groove and a push plate. The No. 2 oil cylinder is installed and fixed on the inner bottom side of the mounting tube. The output end of the No. 2 oil cylinder is fixedly connected to the lower end of the connecting rod. The upper end of the connecting rod is fixedly connected to the lower side of the push plate. A plurality of the slide grooves are opened on the push plate. Each of the grab handles passes through the inside of each slide groove respectively. A rotating mechanism that enables multiple grab handles to rotate simultaneously is provided on the inner side of the limiting sleeve.

[0007] As a further improvement of the above scheme, the rotating mechanism includes a straight slide groove, an inclined slide groove and a clamping rod. The upper end of the straight slide groove is connected to the lower end of the inclined slide groove. Multiple groups of the straight slide grooves and the inclined slide grooves are opened on the inner side of the rotating drum. The multiple groups of the straight slide grooves and the inclined slide grooves are distributed in a circular array on the inner side of the rotating drum. The inner side of each group of the straight slide grooves and the inclined slide grooves is respectively abutted against one end of each clamping rod, and multiple clamping rods are fixedly connected to the outer side of the connecting rod at the same time.

[0008] As a further improvement of the above scheme,

[0009] When the connecting rod pushes each of the clamping rods to move inside each of the straight slide grooves and does not enter the inner side of the inclined slide groove, the push plate only pushes the multiple gripping handles to move closer to each other at the same time;

[0010] When the connecting rod pushes each of the clamping rods from the straight sliding groove into the inner side of the inclined sliding groove, the rotating drum is in a self-rotating state and the plurality of gripping handles are in a rotating and mutually approaching state.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The utility model cooperates with the oil cylinder lifting and lowering mechanism and the clamping rod driving mechanism. When the No. 1 oil cylinder is started, the injection molded workpiece in a low position is initially sent to the grinding processing center. Then the No. 2 oil cylinder is started, and the multiple grips are pushed by the push plate to drive the clamping blocks to move closer to each other, so as to achieve self-centering clamping and fixing of the injection molded workpiece before grinding. In this way, during the grinding process of deburring the outer surface of the cylindrical workpiece, the workpiece can be prevented from deflecting, thereby improving the quality of the deburring and other processing.

[0014] 2. The utility model uses a rotating mechanism. When the No. 2 oil cylinder pushes the clamping rod and moves along the straight slide groove to the oblique slide groove, multiple gripping handles further clamp and fix the outer surface of the cylindrical workpiece while pushing the rotating drum to rotate, driving multiple clamping blocks to clamp the injection molded workpiece and rotate at the same time. The rotation can remove burrs, protrusions and other product defects on the outer surface of the cylindrical injection molded workpiece. The operation is simple and convenient, and the practicality is high. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Below, the present invention is further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0022] Example:

[0023] Please combine Figure 1-Figure 4 The present embodiment is a feeding device for injection molding parts processing, comprising a rotating drum 6, four gripping handles 7, four clamping blocks 8 and four supporting plates 9. The inner surface of the clamping block 8 is a cylindrical curved surface structure. The structure of the gripping handle 7 is as follows. Figure 1 As shown, the four handles 7 form a cone-like spatial distribution structure. The handles 7 are made of tough metal. The upper and lower ends of the rotating drum 6 are fixedly connected with annular baffles. The upper side of the rotating drum 6 is rotatably connected to the lower ends of the four handles 7. The four handles 7 are distributed in a circular array. The upper ends of the four handles 7 are respectively fixedly connected to the lower sides of the support plates 9. The upper sides of the four support plates 9 are respectively fixedly connected to the clamping blocks 8. The lower side of the rotating drum 6 is provided with a sleeve limiting mechanism for limiting and fixing the rotating drum 6. The inner side of the rotating drum 6 is provided with a clamping rod driving mechanism for making the four handles 7 approach each other, grasp and rotate.

[0024] Please combine Figure 1 As shown, the sleeve limiting mechanism includes a mounting cylinder 4 and a limiting sleeve 5. The upper side of the mounting cylinder 4 is fixedly connected to the upper side of the limiting sleeve 5, the inner side of the limiting sleeve 5 is rotatably connected to the outer side of the rotating cylinder 6, and the lower side of the mounting cylinder 4 is provided with a cylinder lifting and lowering mechanism for raising or lowering the mounting cylinder 4.

[0025] Please combine Figure 3 and Figure 4As shown, the card rod driving mechanism includes a No. 2 oil cylinder 12, a connecting rod 13, a slide 10 and a push plate 11. The No. 2 oil cylinder 12 is installed and fixed to the inner bottom side of the mounting tube 4. The output end of the No. 2 oil cylinder 12 is fixedly connected to the lower end of the connecting rod 13. The upper end of the connecting rod 13 is fixedly connected to the lower side of the push plate 11. Four slides 10 are opened through the push plate 11. Each grab handle 7 passes through the inside of each slide 10 respectively. The inner side of the limiting sleeve 5 is provided with a rotating mechanism that enables multiple grab handles 7 to rotate simultaneously.

[0026] It should be noted that the activation of the No. 2 oil cylinder 12 is only responsible for the clamping and fixing of the workpiece by the multiple clamping blocks 8, and is also responsible for the rotation of the rotating drum 6, while the No. 1 oil cylinder 1 is mainly responsible for sending the limiting sleeve 5 into the lifting and lowering of the polishing machining center.

[0027] Please combine Figure 4 As shown, the rotating mechanism includes a straight slide 15, an inclined slide 16 and a clamping rod 14. The upper end of the straight slide 15 is connected to the lower end of the inclined slide 16. Four groups of straight slides 15 and inclined slides 16 are opened on the inner side of the rotating drum 6. The four groups of straight slides 15 and inclined slides 16 are distributed in a circular array on the inner side of the rotating drum 6. The inner side of each group of straight slides 15 and inclined slides 16 is respectively abutted against one end of each clamping rod 14, and multiple clamping rods 14 are fixedly connected to the outer side of the connecting rod 13 at the same time.

[0028] It should be noted that the output end of the No. 2 oil cylinder 12 here can only move up and down, and the output end cannot rotate by itself. Therefore, the connecting rod 13 fixedly connected to the output end of the No. 2 oil cylinder 12 can only punch up and down and cannot rotate by itself.

[0029] When the connecting rod 13 pushes each clamping rod 14 to move inside each straight slide groove 15 and does not enter the inner side of the inclined slide groove 16, the push plate 11 only pushes the multiple gripping handles 7 to move closer to each other at the same time;

[0030] When the connecting rod 13 pushes each clamping rod 14 from the straight slide groove 15 into the inner side of the inclined slide groove 16, the rotating drum 6 is in a self-rotating state and the plurality of gripping handles 7 are in a rotating and mutually approaching state.

[0031] Please combine Figure 1 As shown, the cylinder lifting and lowering mechanism includes a No. 1 cylinder 1, a limit rod 2 and a limit sleeve 3. The output end of the No. 1 cylinder 1 is fixedly connected to the lower side of the mounting cylinder 4, the outer side of the mounting cylinder 4 is fixedly connected to the limit sleeve 3, the limit rod 2 is fixedly connected to one side of the No. 1 cylinder 1, and the limit rod 2 is slidably connected to the inner side of the limit sleeve 3.

[0032] The implementation principle of a loading device for injection molded parts processing in the embodiment of the present application is as follows: the operator first places the injection molded workpiece on the surface of the support plate 9, starts the No. 1 oil cylinder 1, pushes the mounting cylinder 4 to rise upward, and sends the workpiece into the grinding and polishing center, starts the No. 2 oil cylinder 12, pushes the connecting rod 13 to move upward, and the clamping rod 14 is in the movement stage in the straight slide groove 15, pushing the push plate 11 to move upward, driving multiple gripping handles 7 to approach each other. At this time, the multiple clamping blocks 8 at the upper end can achieve a clamping effect on the outer surface of the workpiece. When the connecting rod 13 continues to push upward, the clamping rod 14 enters the inclined slide groove 16 from the straight slide groove 15. At this time, the rotating drum 6 rotates along the inner side of the limiting sleeve 5, driving multiple gripping handles 7 and clamping blocks 8 to rotate at the same time. The workpiece located in the grinding and polishing center achieves a deburring effect on the outer surface under the action of rotation.

[0033] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
