Description

Technical Field

[0001] This utility model relates to the field of tennis machine plastic parts processing technology, and in particular to a device for trimming the gate of a tennis machine hand-tightening bracket injection molded part. Background Technology

[0002] Tennis machines play an important role in tennis training and fitness. They mainly use a launching device to launch tennis balls from a storage tank to a specific area via a control unit. Through the cooperation of sensors and control units, they can launch balls with different forces and angles to different areas to achieve training and fitness effects.

[0003] The hand-cranked brackets of the tennis machine are produced by injection molding machines. The mold can produce multiple brackets at a time. After the injection molded parts are removed, the gate needs to be cut off and the connection between the injection molded parts and the gate needs to be trimmed to avoid rough edges that could injure workers or even affect the installation work. Therefore, trimming is required. The existing trimming method is to trim manually by workers holding a knife and the workpiece. This can easily cause hand injuries and the repair effect is not ideal, with uneven cuts and inconsistent depths. Utility Model Content

[0004] This utility model addresses the deficiencies in the existing technology by providing a device for trimming the gate of a tennis machine hand-tightening bracket injection molded part.

[0005] This utility model is achieved through the following technical solution:

The support frame is fixedly installed inside the collection chamber, the tool holder is fixedly installed on the top of the support frame, the scraper is fixedly connected to the top of the tool holder, and the guide mechanism is installed on the top of the collection chamber. The guide mechanism includes a mounting base, two connecting plates, a guide rod, a first spring, a slider, a locking block, a positioning rod, a spring, a locking shaft, and a second spring. The inner sides of both ends of the mounting base are fixed to the outer sides of the top of the collection chamber, the two connecting plates are fixed to the top of the mounting base, the guide rod is fixedly installed inside the two connecting plates, the first spring and the slider are sleeved on the outer side of the guide rod, the locking block is fixedly installed on the top of the slider, the positioning rod is fixed to the top of the locking block, the top of the locking block has an installation groove, the spring is movably connected to the installation groove on the top of the locking block through the locking shaft, and the second spring is installed at the bottom of the spring.

[0007] In a preferred embodiment of this utility model, a support rod is provided at the bottom of the support frame, located on the outer side of the bottom of the tool holder, and the bottom end of the support rod is fixed to the inner side of the bottom of the collection chamber;

[0008] The struts at the bottom of the support frame effectively support the tool holder, thereby improving the impact resistance of the tool and ensuring the tool installation effect.

[0009] In a preferred embodiment of this utility model, limiting strips are provided on both sides of the bottom of the spring sheet, and the limiting strips on both sides of the spring sheet are engaged with the bottom of the mounting groove on its surface;

[0010] The limiting strips on both sides of the bottom of the spring plate prevent it from being excessively pushed out by the second spring, effectively limiting its movement.

[0011] In a preferred embodiment of the present invention, the top of the slider is provided with a compression groove to facilitate the compression and storage of the spring sheet, and the second spring is disposed in the compression groove at the top of the slider.

[0012] In a preferred embodiment of this utility model, the top of the spring sheet is inclined;

[0013] The spring is ejected at an angle upwards under the action of the second spring, thereby realizing the automatic orientation and feeding of the processed bracket.

[0014] The beneficial effects of this utility model are:

[0015] The ball machine hand-tightening bracket injection molded part gate trimming device is effectively positioned and pressed to fix it. It achieves rapid trimming by pushing and pulling back and forth, ensuring trimming size and effect. After trimming, it pops out through the spring to achieve directional and rapid material discharge. There is no need to manually pick up the material, making the processing fast and convenient.

[0021] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings, so that the advantages and features of this utility model can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of this utility model. The directional terms mentioned in this utility model, such as "up," "down," "front," "back," "left," "right," "top," and "bottom," are only for reference to the accompanying drawings. Therefore, the directional terms used are for the purpose of explaining and understanding this utility model, and not for limiting this utility model.

[0022] like Figure 1-4 The device shown is a gate trimming device for injection molded parts of a tennis machine hand-tightening bracket. It includes a collection chamber 1, a support frame 2, a tool holder 3, a scraper 4, and a guide mechanism 5. The support frame 2 is fixedly installed inside the collection chamber 1, the tool holder 3 is fixedly installed on the top of the support frame 2, and the scraper 4 is fixedly connected to the top of the tool holder 3. The guide mechanism 5 is located on the top of the collection chamber 1 and includes a mounting base 51, two connecting plates 52, a guide rod 53, a first spring 54, a slider 55, a locking block 56, a positioning rod 57, a spring piece 58, a locking shaft 59, and a second... Spring 510, the inner sides of both ends of mounting base 51 are fixed to the outer top of collection chamber 1, two connecting plates 52 are fixed to the top of mounting base 51, guide rod 53 is fixedly set on the inner side of two connecting plates 52, first spring 54 and slider 55 are sleeved on the outer side of guide rod 53, locking block 56 is fixedly set on the top of slider 55, positioning rod 57 is fixed to the top of locking block 56, the top of locking block 56 has an installation groove, spring piece 58 is movably connected to the top installation groove of locking block 56 through locking shaft 59, and second spring 510 is set at the bottom of spring piece 58.

[0023] Specifically, a support rod is provided at the bottom of the support frame 2, located on the outer side of the bottom of the tool holder 3. The bottom end of the support rod is fixed to the inner side of the bottom of the collection chamber 1. Limiting strips are provided on both sides of the bottom of the spring piece 58. The limiting strips on both sides of the spring piece 58 are locked at the bottom of the mounting groove on its surface. A compression groove is provided on the top of the slider 55 to facilitate the compression and storage of the spring piece 58. The second spring 510 is provided in the compression groove on the top of the slider 55. The top of the spring piece 58 is inclined.

[0024] In this embodiment, under the action of the first spring 54, the slider 55 is attached to the inner side of the connecting plate 52 at one end, and then the bracket is installed on the top of the card block 56. The outer side of the card block 56 is attached to the inner wall of the bracket for limitation. The positioning rod 57 is locked in the card hole on the surface of the bracket, and the bracket is installed and fixed by pressing with a finger.

[0025] Furthermore, by pressing the support with fingers and pushing forward by holding the slider 55 with the hand, the slider 55 can be moved forward under the guidance of the guide rod 53, thereby trimming the gate position with the blade of the scraper 4. Since the relative position of the fixed support and the scraper 4 is fixed, the cutting depth and cutting flatness are effectively controlled by pushing and pulling the support. After the cutting is completed, the hand leaves the slider 55, and the slider 55 automatically returns to its original position under the action of the first spring 54. The compressed second spring 510 controls the spring piece 58 to pop out, causing one end of the spring piece 58 to rotate around the retaining shaft 59, controlling the processed support to automatically pop out and fall into the collection chamber 1 for finished product collection.
