Embodiment Construction

[0008] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0009] like figure 1 As shown, the mold provided by the present invention includes male and female templates 1, 2 and a slider 3 between them, the female template 2 is fixed with an oblique guide column 4, the outside of the slider 3 is against a slider seat 5, and the oblique The guide post 4 is inserted in the slider seat 5, the slider seat 5 is stepped, including an upper step surface 51 and a lower step surface 52, the width of the lower step surface 52 is greater than the width of the upper step surface 51, and the inclined guide post 4 is inserted in the lower step surface. on the step surface 52 .

[0010] The traditional inclined guide post 4 is inserted into the upper step surface 51 of the slider seat 5, resulting in the entire slider seat 5 being enlarged. In the present invention, the inclined guide post 4 is only added on the lower step surface 52 of th...

Abstract

The invention discloses a mould comprising a male template, a female template, and a sliding block between the male template and the female template, wherein an inclined guide post is fixedly arranged on the female template; a sliding block base is abutted against the outer side of the sliding block; the inclined guide post is inserted inside the sliding block base; the sliding block base is step-shaped, and comprises an upper step face and a lower step face; the lower step face is more than the upper step face in width; and the inclined guide post is inserted into the lower step face. According to the mould provided by the invention, the inclined guide post is inserted into the lower step face of the sliding block base, so that the contact area of the inclined guide post and the sliding block base becomes smaller, and the rate of deadly clamping is greatly reduced; and furthermore, the width of the edge of the female template can be increased, so that the edge of the female template is prevented from being turned up when being pressed in the injection molding process, the size of a mould frame is reduced, the material cost is saved, and the stability of the entire mould can be improved.

Description

technical field [0001] The invention relates to a mold, in particular to a mold. Background technique [0002] In the traditional mold, when the slider is larger, the inclined guide post is inserted on the entire slider seat, and the inclined guide post is correspondingly larger. The contact surface between the inclined guide post and the slider seat is larger, and the friction force is increased. The probability of getting stuck between them also increases accordingly. [0003] During injection molding, the pressure in the mold is very high, which will warp the edge of the mother template. The existing solution can only increase the edge width of the mother template to increase its strength. After increasing the width, the entire mold base needs to be enlarged, and the corresponding injection molding machine It may also increase, thereby increasing material costs and reducing the stability of the entire mold. Contents of the invention [0004] The technical problem to b...
