Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of mold resetting, in particular to a resetting protection device for an injection mold for producing a plastic tape reel. BACKGROUND

[0002] The shape of a plastic tape reel is usually circular, and in the production process, the inner side cover part of the plastic is usually provided with multiple recessed parts. The tape reel is usually formed by extruding the injection material into a special injection mold. The inner side of the tape reel is provided with grooves of different styles, which are formed by extrusion between the injection mold and the inner side of the injection mold. Different injection molds can be used to produce different sizes of tape reels. After the tape reel is formed, it is demolded.

[0003] The upper and lower ends of the injection mold are extruded to form a tape reel injection part, and the recessed part is clamped with the recessed part of the inner side of the injection mold. In the process of demolding, the position of the injection mold needs to be kept vertical to ensure that the next docking can reduce errors. Maintaining the vertical direction of the same direction will make it easier for the injection part to be pushed out. The demolding of the injection part can only be from the vertical direction, so the adhesion of the injection part in the transverse position may also increase the difficulty of demolding. That is, the transverse part of the injection part lacks protection measures for demolding the mold, and the reasoning of the vertical direction of the injection part demolding may affect the parallel state of the injection mold resetting.

The stacking frame 601 is configured as upper and lower layers. The inner end of the auxiliary frame 602 is located at both ends of the lower stacking frame 601, and the inner end of the stacking plate 604 is located at both ends of the upper stacking frame 601. The top side of the auxiliary frame 602 corresponds to the bottom side of the stacking plate 604. The top end of the push pin 603 is engaged with the bottom side of the stacking plate 604, and the outer side of the push pin 603 penetrates and slides through and is slidably connected to the top inner side of the auxiliary frame 602. After the stacking frame 601 is compressed between the upper and lower layers, the auxiliary frame 602 located at both ends of the stacking frame 601 and the sidewalls of the stacking plate 604 slide back and forth between the upper and lower layers. The movement is achieved by sliding on the outside of the ejector pin 603. Since the inner end of the connecting plate 9 is embedded in the side wall of the stacking mechanism 6, and the inner mating part of the attachment frame 602 and the stacking plate 604 is arc-shaped, when the gap between the attachment frame 602 and the stacking plate 604 decreases, the inner side wall of the connecting plate 9 will sink inward with the arc between the attachment frame 602 and the stacking plate 604. The side wall of the connecting plate 9 will tilt towards the inside of the stacking mechanism 6, and the outer end of the side wall of the connecting plate 9 will tilt upward. The outer end of the connecting plate 9 will move the top of the arc-shaped push plate 10 upward.

[0030] like Figure 1 As shown, in some embodiments, the pressing mechanism 8 includes a top plate 801 and a venting position 802. The bottom side of the venting position 802 is fixedly connected to the top side of the top plate 801, which facilitates the discharge of some air bubbles inside the injection molded part during the injection molding process.

[0031] like Figure 1 As shown, in some embodiments, the sidewall of the arc-shaped push plate 10 is composed of two curved arc-shaped plates connected movably. The inner tip of the middle part of the arc-shaped push plate 10 is movably connected to the outer sidewall of the top of the holding mechanism 4. The inner side of the arc-shaped push plate 10 drives to fit more closely to the outer sidewall of the stacking mechanism 6. At this time, the middle part of the sidewall of the arc-shaped push plate 10 will abut against the outer side of the pressing mechanism 5. When the entire stacking mechanism 6 is pressed down, the middle part of the sidewall of the arc-shaped push plate 10 can poke the outer interface of the holding mechanism 4. After the bottom side of the pressing mechanism 5 and the top of the holding mechanism 4 are separated, the gap between the inner side of the holding mechanism 4 and the sidewall of the inner injection molded part will increase after the sidewall of the holding mechanism 4 is relaxed, which facilitates demolding.

Modifications of these embodiments will occur to persons of skill in the art, and that the appended claims are intended to cover all such modifications that do not depart from the true spirit and scope of the application. Therefore, the application is not limited to the embodiments shown but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
