Description

Mould with ramp down button demolding structure

【Technical field】

The present invention relates to a kind of mould structure, and in particular to a kind of mould with ramp down button demolding structure.

【Background technology】

Fig. 1, Fig. 2 are please referred to, Fig. 1 is a kind of structural representation of product, Fig. 2 is schematically shown as Fig. 1's A-A is to sectional view.As illustrated, having back-off 101 on the product 100, the back-off 101 has larger Angle, common oblique top can not be exited.

In view of this, it is necessary a kind of mould with ramp down button demolding structure of exploitation in fact, to solve above-mentioned ask Topic.

【The content of the invention】

It is therefore an object of the present invention to provide a kind of mould with ramp down button demolding structure, meet have with Product exit axis has exiting for the back-off of larger angle.

In order to achieve the above object, the mould with ramp down button demolding structure of the invention, the mould include according to Caster that sequence is set up, mother module core, male die core, male template, springboard, the inner side of mould molding two have The product of button, the mould of the ramp down button demolding structure also includes：

Two first enter son, are respectively arranged in the male die core, and each described first top for entering son has shaping The forming surface of the back-off of the product, and the described first opposite face for entering son is inclined-plane wide at the top and narrow at the bottom；

Second enters son, and its one end is fixed on the springboard, and the other end is inserted in two described first and entered between son, Enter the inside that son is molded the product jointly with two described first；

Two ejector springs, are respectively arranged in the male die core, and each described ejector spring one end is held in described Nose end in male die core, the other end is held in the corresponding described first outside for entering son；

Shutter, between the male template and the caster.

Optionally, each described first enter sub- bottom have be additionally provided with stopper section, the male die core two it is spacing Block, each limited block correspondence stopper section has limiting section, under matched moulds state, the stopper section with There is a segment distance between the limiting section.

Compared to prior art, the mould with ramp down button demolding structure of the invention, during die sinking, the public affairs First opened between template and the springboard, described second, which enters son, moves downward, depart from the product, the ejection Spring is released due to precompressed, and ejection corresponding described first enters son, and described first enters the sub- disengaging product Back-off；Continue to mold, the shutter is opened, the male template is opened with the caster, product Completely disengage from.It can be seen that, using the mould, can reach it is internal have have larger angle with product exit axis Back-off exit.

【Brief description of the drawings】

Fig. 1 is schematically shown as a kind of structural representation of product.

Fig. 2 is schematically shown as Fig. 1 A-A to sectional view.

Fig. 3 illustrates the mould matched moulds status architecture schematic diagram with ramp down button demolding structure of the present invention.

Fig. 4 illustrates the mould die opening state first stage structural representation with ramp down button demolding structure of the present invention Figure.

Fig. 5 illustrates the mould die opening state second stage structural representation with ramp down button demolding structure of the present invention Figure.

【Embodiment】

Fig. 3 is please referred to, Fig. 3 illustrates the mould matched moulds state knot with ramp down button demolding structure of the present invention Structure schematic diagram.

In order to achieve the above object, the mould with ramp down button demolding structure of the invention, the mould include according to Caster 200 that sequence is set up, mother module core 201, male die core 202, male template 203, springboard 204, the mould The inner side of shaping two has the product 100 of back-off 101, and the mould of the ramp down button demolding structure also includes：

Two first enter son 205, are respectively arranged in the male die core 202, and each described first enters the top of son 205 Portion has a forming surface for the back-off 101 for being molded the product 100, and the phase that described first enters son 205 Opposite is inclined-plane wide at the top and narrow at the bottom；

Second enters son 206, and its one end is fixed on the springboard 204, and the other end is inserted in two described first and entered Between son 205, the inside that son 205 is molded the product 100 jointly is entered with two described first；

Two ejector springs 211, are respectively arranged in the male die core 202, each described one end of ejector spring 211 The nose end in the male die core 202 is held in, the other end is held in corresponding described first and enters the outer of son 205 Side；

Shutter 207, between the male template 203 and the caster 200.

Wherein, in the present embodiment, each described first, which enters sub 205 bottom, has stopper section 209, the male die core Two limited blocks 208 are additionally provided with 202, each correspondence of limited block 208 stopper section 209 has spacing Portion 210, under matched moulds state, has a segment distance between the stopper section 209 and the limiting section 210. After die sinking, together with the limiting section 210 is encountered with the stopper section 209, reach that limitation described first enters son The purpose of 205 move distances.

Referring again to Fig. 4, Fig. 4 illustrates the mould die opening state first with ramp down button demolding structure of the present invention Stage structures schematic diagram.

During die sinking, first opened between the male template 202 and the springboard 204, described second enter son 206 to Lower motion, departs from the product 100, and the ejector spring 211 is released due to precompressed, ejects corresponding institute State first and enter son 205, described first enters the back-off 101 that son 205 departs from the product 100.

Referring again to Fig. 5, Fig. 5 illustrates the mould die opening state second with ramp down button demolding structure of the present invention Stage structures schematic diagram.

Continue to mold, the shutter 207 is opened, the male template 203 and the caster 200 dozens Open, product 100 is completely disengaged from.

It can be seen that, using the mould, can reach it is internal have have larger angle with the exit axis of product 100 Back-off 101 is exited.

It is noted that the invention is not restricted to above-mentioned embodiment, any those skilled in the art's base Any simple modification, equivalent variations and the modification made in technical solution of the present invention to above-described embodiment, all fall Enter in protection scope of the present invention.
