Description

Technical Field

[0001] This utility model relates to the field of plastic products technology, and in particular to a plastic product cutting gate device. Background Technology

[0002] In the production and processing of plastic products, the gate serves as the channel for molten material to enter the mold cavity during injection molding. After the product is molded, it needs to be cut to ensure the integrity of the appearance and performance of the plastic product. Currently, the cutting operation of plastic product gates mostly relies on dedicated cutting devices to achieve automated or semi-automated operation, effectively improving production efficiency. Existing plastic product gate cutting devices typically use blades that cut vertically downwards at a fixed angle, making it impossible to flexibly adjust according to the actual angle of the gate. This necessitates changing cutting components of different specifications or adjusting the entire device layout when dealing with gates of different angles, increasing equipment operating costs and operational complexity. Furthermore, inaccurate angle adaptation can lead to incomplete cutting, surface damage to the product, and reduced production efficiency. Therefore, this utility model proposes a plastic product gate cutting device. Utility Model Content

[0003] The purpose of this invention is to address the problem that in the background technology, the angles are mostly fixed and cannot be flexibly adjusted according to the actual angle of the gate. This leads to the need to replace the cutting components of different specifications or adjust the layout of the entire device when facing gates with different angles. This not only increases the cost of using the equipment and the complexity of operation, but may also result in incomplete cutting and damage to the surface of the product due to inaccurate angle adaptation, thus affecting production efficiency.

[0033] Furthermore, an electric push rod 9 is fixedly installed on the upper surface of the bracket 8. The output end of the electric push rod 9 passes through the bracket 8 and extends to connect to a connecting plate 10. A push plate 11 is fixedly installed on one side of the connecting plate 10, which enables the electric push rod 9 to push the push plate 11 to move stably through the connecting plate 10. The guide sleeve 20 is fixedly connected to the push plate 11 to provide guidance for the push plate 11. A set of second connecting seats 13 is provided on one side of the bracket 8. A connecting rod 14 is rotatably installed on one end of the second connecting seat 13. One end of the connecting rod 14 is rotatably connected to the first connecting seat 3, so that the position of the sliding plate 2 can be adjusted during the rotation of the bracket 8.

[0034] like Figure 1 , Figure 4 and Figure 5 As shown, a cutting assembly 12 for cutting the gate of plastic products is fixedly installed at one end of the push plate 11. The cutting assembly 12 includes a fixing strip 121 fixedly installed on one side of the push plate 11. A slot 122 is opened on one side of the fixing strip 121. A locking block 123 is slidably installed inside the slot 122, which can stably lock the locking block 123 and the slot 122. A blade 124 is fixedly installed on the bottom surface of the locking block 123, which is convenient for replacing the blade 124. A threaded hole 125 is opened at one end of the fixing strip 121. A limit bolt 126 is threadedly sleeved inside the threaded hole 125. A sleeve block 127 is movably sleeved on the outer wall of the limit bolt 126. An insert block 128 is fixedly installed on one side of the sleeve block 127. The limit bolt 126 is limited by the threaded hole 125. The limit bolt 126 limits the sleeve block 127 and the insert block 128, which facilitates the replacement of the blade 124.

[0035] like Figure 1 and Figure 3 As shown, a limiting component 15 for adjusting the angle of the cutting assembly 12 is fixedly installed on the upper surface of the support frame 4. The limiting component 15 includes a guide frame 151 fixedly installed on the upper surface of the support frame 4. The guide frame 151 has an arc-shaped structure. A guide groove 152 is opened on one side of the guide frame 151. A threaded rod 153 is slidably installed inside the guide groove 152. One end of the threaded rod 153 is fixedly connected to the bracket 8, which enables the bracket 8 to rotate according to the direction of the guide frame 151, thereby improving the stability of the rotation. A nut 154 is threaded onto the outer wall of the threaded rod 153. Through the threaded engagement of the nut 154 and the threaded rod 153, the bracket 8 can be stably limited.

[0036] The working principle of this embodiment is as follows: First, the angle of the cutting component 12 is adjusted according to the gate of the plastic product to be cut. The nut 154 is loosened on the threaded rod 153. At this time, the threaded rod 153 can slide in the guide groove 152 of the guide frame 151. Since the bracket 8 is rotatably connected to the fixed seat 5 through the shaft 6, and one end of the threaded rod 153 is fixed to the bracket 8, the bracket 8 is pushed to rotate around the shaft 6 as the rotation axis. The threaded rod 153 slides along the arc-shaped guide groove 152. After adjusting to the appropriate gate angle, the nut 154 is tightened. Through the threaded engagement between the nut 154 and the threaded rod 153, the bracket 8 is stably limited, and the precise adjustment of the cutting angle is completed.

[0037] During the adjustment process, the bracket 8 drives the linkage rod 14 to move through the second connecting seat 13, the linkage rod 14 drives the first connecting seat 3 to move, the first connecting seat 3 drives the sliding plate 2 to slide horizontally between the base plate 1 through the guide of the sliding groove 16 and the sliding block 17, and the sliding plate 2 drives the through groove 18 on it to move.

[0038] Next, place the plastic product to be cut on the sliding plate 2, aligning its gate with the underside of the blade 124 of the cutting assembly 12. Activate the electric push rod 9; its output end pushes the push plate 11 via the connecting plate 10. The push plate 11 drives the guide sleeve 20 to slide stably along the guide rail 19 on the bracket 8, simultaneously pushing the cutting assembly 12 downwards. When the blade 124 contacts the gate, as the push plate 11 continues to advance, the blade 124 completely cuts the gate through the through-slot 18 on the sliding plate 2.

[0039] After the cutting is completed, the electric push rod 9 retracts, causing the cutting assembly 12 to reset, and the sliding plate 2 also returns to its initial position.

[0040] When the blade 124 is damaged or needs to be replaced with a blade 124 adapted to different cutting requirements, unscrew the limiting bolt 126 from the inside of the threaded hole 125, and pull out the insert block 128 on one side of the sleeve block 127 from the inside of the slot 122. Then slide the retaining block 123 out of the slot 122 of the fixing strip 121 to remove the old blade 124. Slide the retaining block 123 of the new blade 124 into the slot 122, then insert the insert block 128 into the inside of the slot 122. Insert one end of the limiting bolt 126 through the sleeve block 127 and into the threaded hole 125, and rotate the limiting bolt 126 in the opposite direction to stably insert it into the inside of the threaded hole 125, completing the blade 124 replacement. The whole process is quick and convenient, greatly reducing equipment downtime.

[0041] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
