Description

Technical Field

[0001] This utility model relates to the field of post-processing technology for injection molded parts, and in particular to an automatic shearing and grinding device for injection molded parts. Background Technology

[0002] In the injection molding process of plastic products, molten plastic fills the mold cavity through runners (i.e., main runners and branch runners). After molding, the product solidifies and connects with the runner system that transported the plastic; these connecting parts are commonly referred to as "runner solids." Therefore, after the injection molded part is demolded, subsequent processing is necessary to separate the runner solids from the product body.

[0003] Currently, the processing of runner sprue in injection molded parts is generally done manually. The specific process is as follows: the operator first uses tools such as shears to manually cut off the runner sprue attached to the injection molded part; since the shearing operation usually does not make the surface of the injection molded part smooth, leaving protruding burrs or sprue heads on the product body, after cutting off the runner sprue, the operator also needs to use tools such as files and sandpaper to manually polish the remaining sprue heads to make the product surface achieve the process requirements of smooth and flat surface.

[0004] This traditional manual operation method has many drawbacks: First, it relies heavily on manpower, is labor-intensive, and requires a high level of skill from the operators; second, it has low production efficiency, as cutting and polishing each piece individually restricts the overall output efficiency and makes it difficult to meet the needs of large-scale production; third, manual operation has poor quality stability, and fatigue or negligence can easily lead to uneven product ends, surface scratches, or even product damage, resulting in a decrease in yield and material waste.

Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0024] The present invention provides an automatic shearing and grinding device for injection molded parts, comprising a shearing mechanism and a grinding mechanism. The injection molded part includes two main bodies 20 and a runner slurry 21 connecting the two main bodies 20; as shown... Figure 1As shown, the shearing mechanism includes a shearing section and a moving section. The shearing section includes two shearing members 31. The moving section is used to clamp the two main bodies 20 and move the injection molded part through the two shearing members 31 in sequence. The two shearing members 31 are used to cut off the runner solidified material 21 to separate it from the main body 20; as shown... Figure 2 As shown, the grinding mechanism includes a clamping component and a grinding component located above the clamping component. Several main bodies 20 are clamped and fixed on the clamping component. After being cut by the shearing mechanism, the main bodies 20 have protruding material heads 22. The grinding component is used to grind the material heads 22 on the main bodies 20.

[0025] like Figure 1 As shown, the moving part includes clamping components and a moving component that drives the clamping components to move. Two clamping components respectively clamp two main bodies 20. The moving component drives the clamping components to move and causes the injection molded part to pass sequentially through two shearing components 31. The moving component includes a lead screw linear module. The clamping component includes a mounting plate 23 and two clamping cylinders 24 fixed on the mounting plate 23. The two clamping cylinders 24 respectively clamp the two main bodies 20. The moving component is connected to the mounting plate 23 to drive the overall movement of the clamping component.

[0026] The shearing component 31 is one of a hydraulic shear, a pneumatic shear, or an electric shear. The grinding component is one of a rotary grinding wheel, a belt sander, or a milling cutter. The grinding component includes a grinding section and a driving component that drives the grinding section to move, so that the grinding section grinds the material heads 22 on each main body 20 sequentially or simultaneously.

[0027] like Figure 2 As shown, the clamping component includes a base plate 25 and several clamps 26 disposed on the base plate 25. The base plate 25 has several recesses 27 for placing the main body 20, and these recesses 27 are spaced apart along the length of the base plate 25. The clamps 26 are used to clamp and fix the main body 20 within the recesses 27. The depth of each recess 27 is less than the height of the main body 20, so that when the main body 20 is placed in the recess 27, the material head 22 on the main body 20 is completely exposed outside the recess 27. A groove 28 is also provided on the base plate 25, extending through the recess 27 along the length of the base plate 25. The width of the groove 28 is less than the width of the recess 27. The groove 28 facilitates the removal of the main body 20 from the recess 27.

The size of the recess 29 is adapted to the size of the main body 20.

[0029] The automatic shearing and grinding device for injection molded parts described in this utility model has the following working process: After mold opening, the moving component drives the clamping component to move, precisely clamping the two main bodies 20 of the injection molded part. The moving component then moves the injection molded part out of the mold. Subsequently, the moving component moves the injection molded part, first moving the connection part of the runner solidified material 21 on one side to the cutting edge of the first shearing component 31, completing the first shearing. Next, the moving component adjusts the position of the injection molded part, moving the connection part of the runner solidified material 21 on the other side to the second shearing component 31 for a second shearing. After two shearings, the runner solidified material 21 is completely separated from the two main bodies 20, leaving a protruding sprue head 22 on each main body 20. Then, the sheared main bodies 20 are transferred to the grinding mechanism. Multiple main bodies 20 are neatly placed in the cavity 27 of the base plate 25 and fixed. The grinding component above the clamping component grinds the sprue head 22 on each main body 20 sequentially or simultaneously, removing burrs and protrusions, making the area smooth and flat, meeting the product's process requirements.
