Abstract
The utility model discloses an auxiliary core pulling structure of a plastic mold. The plastic mold comprises a fixed mold plate, a movable mold plate and a cavity. A core is arranged in the cavity. A movable mold bottom plate is arranged at the lower end of the movable mold plate. The auxiliary core pulling structure is characterized in that an ejector pin installation plate is arranged on the movable mold bottom plate, a sliding seat which can slide on the ejector pin installation plate is arranged on the ejector pin installation plate, an oblique ejector rod is fixedly arranged on the sliding seat, a guide block is arranged at the lower end of the movable mold plate, the upper end of the oblique ejector rod penetrates through the guide block and is fixed with the core, and a guide sliding rod is additionally connected between the guide block and the sliding seat. By adding the guide sliding rod between the guide block and the sliding seat, when the oblique ejector rod pulls the core, the sliding seat slides with the guide sliding rod. Very small friction is produced between the oblique ejector rod and the guide block, the force applied to the oblique ejector rod is very small, the oblique ejector rod is prevented from being bent and damaged, the mold and products are prevented from being damaged during core pulling and the machining is very convenient.
Description
[technical field]
The utility model relates to a kind of auxiliary structure of loosing core of plastic mould.
[background technology]
Existing plastic mould or plastic cement products when relating to side core-pulling, all adopt the mode of loosing core of tiltedly pushing up.The action of loosing core receives the restriction of angle and ejection stroke, so tiltedly withstands on when loosing core guide pad and tiltedly produces very big friction between the top, tiltedly pushes up stressed very greatly, causes bending of oblique top and damage easily, and mould needs repairing.Therefore cause to produce to stop, causing damage to corporate economy.
[utility model content]
The purpose of the utility model is to overcome the weak point of prior art, and a kind of prevent angle ejector rod bending and damage are provided, and guarantees when action is loosed core in completion, can not decrease the auxiliary structure of loosing core of the plastic mould of mark mould and product.
The purpose of the utility model is achieved in that
A kind of auxiliary structure of loosing core of plastic mould; Described plastic mould comprises solid plate, moving platen, die cavity, is provided with core in the die cavity, and the lower end of moving platen is provided with moving clamping plate; It is characterized in that moving clamping plate is provided with the thimble installing plate; The thimble installing plate is provided with the sliding seat that can on the thimble installing plate, slide, and is fixed with angle ejector rod on the sliding seat, and the lower end of described moving platen is provided with guide pad; The upper end of angle ejector rod passes guide pad and core is fixed, and also is connected with the slide guide bar between described guide pad and the sliding seat.
The auxiliary structure of loosing core of aforesaid a kind of plastic mould is characterized in that described slide guide bar lower end and moving clamping plate fix.
The auxiliary structure of loosing core of aforesaid a kind of plastic mould is characterized in that described thimble installing plate comprises thimble installation panel and thimble installation base plate.
The auxiliary structure of loosing core of aforesaid a kind of plastic mould is characterized in that described slide guide bar fixes through a mount pad and sliding seat.
The auxiliary structure of loosing core of aforesaid a kind of plastic mould is characterized in that also being provided with between described moving clamping plate and the moving platen square iron.
The utility model increases the slide guide bar between guide pad and sliding seat, when angle ejector rod is loosed core, make sliding seat follow the slide guide bar and slide together.Produce very little friction between angle ejector rod and the guide pad, angle ejector rod is stressed very little, can not cause angle ejector rod bending and damage, guarantees when action is loosed core in completion, not decrease mark mould and product, and processes very convenient.
[description of drawings]
Fig. 1 is the utility model structural representation.
[specific embodiment]
As shown in Figure 1, a kind of auxiliary structure of loosing core of plastic mould, described plastic mould comprises solid plate 1, moving platen 2, die cavity 3, product 100; Be provided with core 4 in the die cavity 3, the lower end of moving platen 2 is provided with moving clamping plate 21, and moving clamping plate 21 is provided with thimble installing plate 5; Thimble installing plate 5 is provided with the sliding seat 6 that can on thimble installing plate 5, slide; Be fixed with angle ejector rod 7 on the sliding seat 6, the lower end of described moving platen 2 is provided with guide pad 22, and it is fixing with core 4 that guide pad 22 is passed in the upper end of angle ejector rod 7; Also be connected with slide guide bar 8 between described guide pad 22 and the sliding seat 6, slide guide bar 8 lower ends and moving clamping plate 21 are fixing.When angle ejector rod 7 is loosed core, make sliding seat 6 follow slide guide bar 8 and slide together.Produce very little friction between angle ejector rod 7 and the guide pad 22, angle ejector rod 7 is stressed very little, can not cause angle ejector rod 7 bendings and damage, guarantees when action is loosed core in completion, can not decrease mark mould and product.
Slide guide bar 8 is fixing with sliding seat 6 through a mount pad 81.
Also be provided with square iron 9 between moving clamping plate 21 and the moving platen 2.
The outer wall of angle ejector rod 7 is provided with tooth, and guide pad 22 is provided with teeth groove, and angle ejector rod 7 can be rotated on guide pad 22.
