Description

Technical Field

[0001] The present application relates to the technical field of flattening equipment, and in particular to an injection molded part flattening equipment. Background Art

[0002] After molding, injection molded parts need to be shaped before they can be packaged and shipped. During the shaping process, the injection molded parts need to be flattened by a flattening device to ensure that the shape of the parts meets the standard. The existing flattening device includes two upper and lower pressing plates that are arranged opposite to each other, and a driving member that drives the upper pressing plate to move toward the lower pressing plate. It is usually used to flatten relatively flat parts. However, for a special-shaped part, such as Figure 1 As shown, it includes a transverse plate and folded edges arranged at both ends of the transverse plate, which makes it difficult for existing flattening equipment to place the part so as to flatten the transverse plate in the part, so further improvement is needed.

[0006] By adopting the above technical solution, the two folded edges in the part body are first inserted into the two positioning grooves for positioning through the provided positioning plate, and then the driving member is started to drive the upper mold to move toward the lower mold to flatten the part body with a special-shaped setting, and the flattening of the special-shaped part is achieved through the provided positioning blocks and positioning grooves.

[0008] By adopting the above technical solution, a plurality of positioning grooves are provided to place a plurality of parts, and when the driving member is opened and closed once, the plurality of parts can be pressed together, thereby speeding up the pressing efficiency.

[0009] Preferably, a rubber pad is provided on the lower surface of the upper mold.

[0010] By adopting the above technical solution, a rubber pad is provided, and the softness and elasticity of the rubber pad itself can, on the one hand, reduce the damage caused by the pressing force when the upper mold presses the part body, and on the other hand, increase the contact area between the upper mold and the part body when under pressure, that is, the corresponding friction force, thereby reducing the possibility of relative slippage of the part body during the pressing process, thereby further improving the pressing effect on the part body.

[0011] Preferably, the frame is provided with a control button, two of the control buttons are arranged at intervals along the length direction of the frame, and the control button is electrically connected to the driving member.

[0012] By adopting the above technical solution, a control button is provided so that the driving member can be opened and closed as needed to flatten the injection molded parts. Since two control buttons are provided, the possibility of accidental injury to the operator's hand after touching it when only one control button is provided is reduced.

[0013] Preferably, the positioning plate includes a placement plate for placing the part body and positioning strips arranged on two opposite sides of the placement plate, a plurality of positioning strips are arranged at intervals along the length direction of the placement plate, and the spacing between adjacent positioning strips forms the positioning groove, and the lower mold is provided with a connecting piece, and the positioning strip is detachably connected to the lower mold through the connecting piece.

[0014] By adopting the above technical solution, the positioning strip is detachably connected to the lower mold so that positioning strips of different lengths can be replaced according to the width of the part body, thereby improving the applicability of the flattening equipment and reducing the cost and difficulty of replacement caused by the need to equip positioning plates of different lengths.

[0015] Preferably, the positioning strip comprises a plurality of positioning blocks, and two opposite side walls of the positioning blocks are protrudingly provided with protrusions and slots, and the protrusions are slidably inserted in the slots.

[0016] By adopting the above technical solution, the positioning strip includes a plurality of positioning blocks, and the number of positioning slots is adjusted according to the fit between the protrusions and the slots, so that the injection molded parts can be flattened according to the needs. In addition, due to the fit between the protrusions and the slots, the installation time required for installing a plurality of positioning blocks with a plurality of connectors is reduced, and the cost required for equipping a plurality of positioning strips of different lengths is reduced.

[0017] Preferably, the placement plate includes a plurality of placement strips spaced apart along the width direction of the lower mold, the lower mold is provided with a connecting piece, and the placement strips are detachably connected to the lower mold through the connecting piece.

[0018] By adopting the above technical solution, since the lengths of part bodies of different sizes are different, the required distances between the two relative positioning grooves are different. In order to reduce the cost of equipping placement plates of different widths, the placement plate includes a plurality of placement strips spaced along the width direction of the lower mold, and a corresponding number of placement strips are installed according to needs to adapt to the positioning grooves required by part bodies of different sizes, so as to improve the adaptability of the flattening equipment.

[0019] Preferably, two opposite side walls of the placement strip are respectively provided with a groove and a convex strip, and the convex strip is slidably inserted in the groove.

[0020] By adopting the above technical solution, through the cooperation between the convex strips and the grooves, the time and difficulty of installing several placement strips on the lower mold can be reduced, so as to speed up the replacement rate and reduce the flattening efficiency of the part body.

[0021] In summary, the utility model has the following beneficial effects:

[0022] 1. Through the provided positioning plate, the two folded edges in the part body are first inserted into the two positioning grooves for positioning, and then the driving part is started to drive the upper die to move toward the lower die to flatten the part body with a special-shaped setting. The positioning block and positioning groove are used to flatten the special-shaped part.

[0023] 2. By making the positioning strips and the placement plates detachably connected to the lower mold, positioning strips of different lengths and placement plates of different widths can be replaced according to the width of the part body, so as to improve the application range of the flattening equipment and reduce the cost and replacement difficulty caused by equipping positioning plates of different lengths and placement plates of different widths.
