Description

Technical Field

[0001] This utility model belongs to the field of mechanical equipment technology, and in particular relates to a device for removing sprue marks from injection molded parts. Background Technology

[0002] A sprue is the joint between the frame and the parts formed during the casting process in a factory. It is also called a "gate" or "gating point," meaning the inlet or outlet for the flow of heated liquid material.

[0003] In actual production, injection molding machines typically leave sprue marks on the molded product. Therefore, after demolding, the sprue marks need to be trimmed, leaving only the main body of the product. Current methods for sprue removal mostly involve manual trimming, which is inefficient, requires high labor costs, and negatively impacts production efficiency.

[0004] Therefore, there is a need to provide a device for removing sprue marks from injection molded parts. Utility Model Content

[0005] The main purpose of this utility model is to provide a device for removing sprue marks from injection molded parts, addressing the shortcomings of existing technologies.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A device for removing sprue marks from injection molded parts includes a bracket, on which guide posts are provided.

[0008] The water-cutting mechanism includes two water-cutting components, and the two water-cutting components are connected to the guide post;

[0009] The water cutter assembly includes a mounting frame and a pneumatic shear, the mounting frame is connected to the guide post, and the pneumatic shear is mounted on the mounting frame;

[0010] A clamping mechanism is provided above the sprue mechanism and is used to clamp the injection molded part;

[0011] The clamping mechanism moves the injection molded part above the pneumatic shears, which then cut the part at the junction of the sprue and the branch gate.

[0012] Preferably, the two shear nozzle assemblies are arranged in parallel.

[0013] Preferably, the clamping mechanism includes a movable clamping plate, and the clamping plate has a plurality of vacuum nozzles on both sides of its surface that can adsorb injection molded parts.

[0014] Preferably, the bottom of the clamping plate is provided with a pneumatic clamp for clamping the main sprue of the injection molded part.

[0015] Preferably, the clamping plate is provided with a clearance hole, which is located above the pneumatic clamp.

[0016] Preferably, the guide post is provided with a mounting groove, and the mounting bracket and the guide post are slidably engaged and locked relative to each other by a fixing member.

[0017] Preferably, the mounting bracket is symmetrically provided with a first groove and a second groove, and the fixing member passes through the first groove, the second groove and the mounting groove, so that the mounting bracket and the guide post slide together and are locked relative to each other.

[0018] Preferably, a gasket is fitted onto the outer periphery of the fastener.

[0019] Compared with the prior art, the present invention will have at least the following beneficial effects:

[0020] ①This utility model improves the accuracy and efficiency of sprue removal by setting two sprue removal components to simultaneously remove sprues from injection molded parts, enabling continuous industrial production.

[0021] ②This utility model eliminates the need for manual cutting of the sprue, improving work efficiency and reducing production costs.

[0022] ③ The mounting bracket is symmetrically provided with a first groove and a second groove. The setting of the fixing member passing through the first groove, the second groove and the mounting groove can make the mounting bracket slide and lock relative to the guide column. Furthermore, the relative position of the mounting bracket on the guide column can be adjusted by adjusting the position of the fixing member, thereby synchronously adjusting the position of the pneumatic scissors on the mounting bracket. This enables the cutting of the sprue of injection molded products of different sizes. Attached Figure Description

[0031] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely exemplary embodiments of this utility model, and not the only embodiments.

[0032] Depending on the actual needs of injection molding, the injection molded part may be formed through a main hot runner with multiple branch runners. Therefore, the injection molded part may have multiple gates. In this embodiment, taking one main hot runner and two branch hot runners as an example, the molded injection molded part has two gate positions and three gates. The three gates include the main gate and two branch gates, with the two branch gates located on both sides of the bottom of the main gate and respectively connected to the corresponding gate positions. The gates of the injection molded part can be removed by cutting off the parts where the branch gates are connected to the corresponding gate positions. The specific solution is as follows:

[0033] like Figures 1 to 5 As shown, an injection molding part sprue removal device includes a bracket 1 with a guide post 2 on the bracket 1, and a sprue cutting mechanism. The sprue cutting mechanism includes two identical sprue cutting assemblies connected to the guide post 2. Each sprue cutting assembly includes a mounting frame 3 and a pneumatic shear 4. The mounting frame 3 is connected to the guide post 2, and the pneumatic shear 4 is mounted on the mounting frame 3. A clamping mechanism is also included, located above the sprue cutting mechanism, for clamping the injection molding part 16. After the injection molding part 16 is formed, the clamping mechanism moves the formed injection molding part 16 above the pneumatic shear 4, activates the pneumatic shear 4, and cuts the part where the sprue position 7 of the injection molding part 16 meets the sprue outlet 6.

[0034] To facilitate simultaneous gate shearing at the junction of gate 7 and gate 6, two gate shearing assemblies are connected in parallel on guide post 2. This allows the two gate shearing assemblies to simultaneously shear the gates at both ends of the injection-molded part 16.

[0035] The clamping mechanism includes a movable clamping plate 8. Several vacuum nozzles 9 are provided on both sides of the surface of the clamping plate 8 to adsorb the injection molded part 16. The clamping plate 8 is moved by a robot. It is understood that the robot is existing technology and is not shown in this embodiment and the accompanying drawings, but it does not prevent those skilled in the art from understanding this technical solution. After the vacuum nozzles 9 adsorb the injection molded part 16, the robot transfers the injection molded part 16 to the top of the pneumatic scissors 4 for sprue cutting.

[0036] The bottom of the clamping plate 8 is provided with a pneumatic clamp 10 for clamping the main gate 5. Specifically, the pneumatic clamp 10 is used to clamp the main gate 5 on the injection molded part 16 to strengthen the position fixation of the injection molded part 16.

[0037] The clamping plate 8 is provided with a clearance hole 11, which is located above the pneumatic clamp 10. This allows the position of the pneumatic clamp 10 clamping the main sprue 5 to be adjusted according to the actual situation of the injection molded part 16. The clearance hole 11 facilitates the pneumatic clamp 10 to clamp the main sprue 5 and avoids interference between the clamping plate 8 and the main sprue 5. In other words, the clearance hole 11 on the clamping plate 8 can make way for the main sprue 5, which makes it easier for the pneumatic clamp 10 to clamp the main sprue 5.

[0038] like Figure 2 As shown, the guide post 2 is provided with a mounting groove 17. The mounting bracket 3 and the guide post 2 are slidably engaged and locked relative to each other by a fixing member 14. This allows the mounting bracket 3 and the guide post 2 to slide and lock within the mounting groove 17. The fixing member 14 can be quickly removed and tightened, which facilitates the adjustment of the positional relationship between the mounting bracket 3 and the guide post 2 and enables the mounting bracket 3 and the guide post 2 to be locked relative to each other within the mounting groove 17.

[0039] Specifically, the mounting bracket 3 is symmetrically provided with a first groove 12 and a second groove 13. A fixing member 14 passes through the first groove 12, the second groove 13, and the mounting groove 17, allowing the mounting bracket 3 and the guide post 2 to slide and lock relative to each other within the mounting groove 17. In actual use, the fixing member 14 passes through the first groove 12 and the mounting groove 17, while another fixing member 14 passes through the second groove 13 and the mounting groove 17. This allows the mounting bracket 3 and the guide post 2 to achieve a sliding fit and relative locking. When the dimensions of the injection-molded part 16 and the sprue are... When changes occur, loosen the fixing piece 14, adjust the position of the mounting bracket 3 on the guide post 2, then pass the fixing piece 14 through the first groove 12 and the mounting groove 17, and at the same time pass the other fixing piece 14 through the second groove 13 and the mounting groove 17, so that the mounting bracket 3 and the guide post 2 are locked. After the position of the mounting bracket 3 is adjusted, the position of the pneumatic shear 4 set on the mounting bracket 3 is adjusted synchronously with the mounting bracket 3. Start the pneumatic shear 4 to complete the sprue cutting operation. Therefore, it is possible to cut the sprue of injection molded parts 16 of different sizes.

[0040] A gasket 15 is fitted around the outer periphery of the fastener 14. Specifically, the gasket 15 is located between the first groove 12 or the second groove 13 and the fastener 14. The gasket 15 can strengthen the fastening effect of the fastener 14, thereby strengthening the locking mounting bracket 3 and the guide post 2.

[0041] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
