Abstract
The utility model provides an anti-collision gasket for a return rod of an injection mold. The anti-collision gasket comprises an upper template and a lower template and of the mold, wherein the upper template is connected with a cavity; mold feet are mounted on the lower template; a mold core is mounted on the mold feet; the mold core is matched with the cavity; a lower ejector plate and an upper ejector plate are arranged between the mold feet; the return rod is connected to the upper ejector plate; the anti-collision gasket is characterized in that a recess is formed in a parting surface of the cavity; the anti-collision gasket is mounted in the recess; the anti-collision gasket is fixed by a bolt; and the return rod is in contact with the anti-collision gasket after penetrating through the mold core. After the anti-collision gasket is arranged in the technical scheme, the hardness of the anti-collision gasket is treated to HRC55; the anti-collision gasket with high hardness and wear resistance is embedded in the recess of the parting surface of the mold cavity, corresponds to the return rod, is used for preventing the return rod from colliding with the mold during returning and is fixed by the bolt, so that convenience in replacement is achieved.
Description
Technical field
The utility model relates to a kind of injection mold release link pad, belongs to the mould of plastics field.
Background technology
The die joint of traditional injection mold (mold cavity surface) is not all installed crashproof pad; In the die production process, because the die sinking and the matched moulds that do not stop, mould die joint and release link are clashed into phenomenons such as depression can occur for a long time; Thereby it is not in place to cause mould to reset; Being uneven appears in all mechanisms that need the release link drive to reset such as ejector pin of die set, jacking block, and product defect is when serious even because of the mould that breaks not in place that resets.
Summary of the invention
The purpose of the utility model is in order to overcome the shortcoming of prior art, to provide a kind of and at mold cavity surface crashproof pad is installed, prevent that mould from breaking, caving in, high hard, the wear-resisting crashproof pad of injection mold release link.
The technical scheme of the crashproof pad of the utility model injection mold release link is: comprise upper mould plate and lower bolster, cope match-plate pattern connects die cavity, and the mould pin is installed on the lower bolster; On the mould pin core is installed, core matches with die cavity, and lower roof plate and upper plate are set between the mould pin; Connect release link on the upper plate, it is characterized in that being shaped on groove on the described die cavity somatotype surface, crashproof pad is installed in the groove; Crashproof pad is fixed by screw, and release link is passed core and contacted with preventing pad.
The crashproof pad of injection mold release link of the utility model, crashproof pad has been arranged after, the hardness of crashproof pad is handled to HRC55; Hardness is high, and is wear-resisting, is embedded in the groove on somatotype surface of mold cavity; Corresponding with release link; Prevent that release link from breaking mould when resetting, and fix that it is convenient to change by screw.
Description of drawings
Fig. 1 is the utility model injection mold release link bumper chip architecture sketch map.
The specific embodiment
The utility model relates to the crashproof pad of a kind of injection mold release link, and is as shown in Figure 1, comprises upper mould plate 1 and lower bolster 2; Cope match-plate pattern 1 connects die cavity 3, and mould pin 4 is installed on the lower bolster 2, and core 5 is installed on the mould pin 4; Core 5 matches with die cavity 4, and lower roof plate 6 and upper plate 7 are set between the mould pin 4, connects release link 8 on the upper plate 7; It is characterized in that being shaped on groove 9 on the described die cavity 3 somatotype surfaces; Crashproof pad 10 is installed in the groove 9, and crashproof pad 10 is fixed by screw 11, and release link 8 is passed core 5 and contacted with preventing pad 10.This programme after crashproof pad 10 has been arranged is handled the hardness of crashproof pad 10 to HRC55, and hardness is high; Wear-resisting, be embedded in the groove 9 on somatotype surface of mold cavity, corresponding with release link 8; Prevent that release link 8 from breaking mould when resetting, and fix that it is convenient to change by screw 11.
