Description

Technical Field

[0001] This utility model relates to the field of injection molding part gate removal technology, and in particular to an injection molding part gate removal device. Background Technology

[0002] The sprue is the connecting part between the frame and the injection molded part formed during the injection molding process. The sprue is an extra part on the injection molded part and needs to be removed from the injection molded part.

[0003] In factory production, sprue gates are typically cut or trimmed off from injection molded parts manually using scissors or specialized tools. However, manual sprue gate removal is inefficient and produces inconsistent quality, often resulting in uneven cuts and excessive residue, which affects the product's appearance and performance, and cannot meet the demands of large-scale production.

[0032] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0033] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0035] Please see Figures 1 to 8 This invention provides an injection molding part sprue removal device according to one embodiment of the present invention, comprising a cabinet 10, an indexing plate 20 installed in the middle of the top surface of the cabinet 10, a cutting component 30 installed on one side of the indexing plate 20, a sprue removal component 40 located on one side of the cutting component 30, and a product unloading component 50 located on the side of the sprue removal component 40 away from the cutting component 30. Specifically, the cutting component 30, the sprue removal component 40, and the product unloading component 50 are evenly spaced around the indexing plate 20.

[0036] The indexing plate 20 has multiple jigs 21 evenly arranged on its top surface. The jigs 21 are used for positioning and loading the injection molded part 22. Figure 3 As shown, the injection molded part 22 includes a sprue 221 and four products 222 evenly spaced and connected to the bottom end of the sprue 221. The fixture 21 is roughly square in shape, and positioning holes 23 are provided on opposite sides of the fixture 21. The two positioning holes 23 are centrally symmetrical about the center of the fixture 21.

[0037] The cutting assembly 30 includes a support 31 installed on one side of the indexing plate 20, a lifting cylinder 32 installed on the top of the support 31, a lifting plate 33 connected to the piston rod of the lifting cylinder 32, four cutters 34 installed in the middle of the bottom surface of the lifting plate 33, a floating plate 35 elastically connected to the bottom of the lifting plate 33, and positioning pins 36 installed on opposite sides of the lifting plate 33; the positioning pins 36 correspond one-to-one with the positioning holes 23.

[0038] Specifically, such as Figure 5 and Figure 6 As shown, the floating plate 35 is used to elastically abut against the product 222; the floating plate 35 has a through hole in the middle for the cutter 34 and the sprue 221 to pass through. The four cutters 34 are connected end to end in a square arrangement. The cutters 34 are used to cut off the connection between the sprue 221 and the product 222 to separate the sprue 221 from the product 222.

[0039] Furthermore, guide rods 330 are connected to opposite sides of the top surface of the lifting plate 33, and the guide rods 330 are slidably connected to the top of the support 31, which effectively improves the stability of the lifting movement of the lifting plate 33.

[0040] The sprue removal assembly 40 includes a push-pull cylinder 41 connected to the cabinet 10, a first slide cylinder 42 connected to the piston rod of the push-pull cylinder 41, a pneumatic finger 43 installed at the end of the first slide cylinder 42, and a sprue collection box 44 installed below the push-pull cylinder 41. The pneumatic finger 43 is located above the indexing plate 20 and is used to grip the sprue 221 and transfer it into the sprue collection box 44, leaving only the individual product 222.

[0041] In this embodiment, the extension and retraction direction of the push-pull cylinder 41 is consistent with the radial direction of the indexing plate 20.

[0042] The product unloading assembly 50 includes a horizontal linear module 51 connected to the cabinet 10, a second slide cylinder 52 connected to the slide of the horizontal linear module 51, a fixing plate 53 connected to the end of the second slide cylinder 52, a plurality of vacuum nozzles 54 evenly spaced on the fixing plate 53, and a product collection box 55 located at the end of the horizontal linear module 51 away from the indexing plate 20; wherein, the vacuum nozzles 54 are located above the indexing plate 20, and the vacuum nozzles 54 are used to adsorb the product 222 and transfer the product 222 to the product collection box 55.

[0043] In this embodiment, the movement direction of the transverse linear module 51 is consistent with the radial direction of the indexing plate 20.

[0044] The above-mentioned injection molding part gate cutting equipment has a simple structure and is easy to use. It uses a floating plate 35 to elastically abut against the product 222, and the cutter 34 falls to accurately cut the connection between the gate 221 and the product 222. Then, the gate removal component 40 and the product unloading component 50 collect them separately, which greatly improves the degree of automation and improves the cutting efficiency and cutting quality.

[0045] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0046] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
