Abstract
The utility model discloses a kind of hot pressing die with precompressed flange, including upper die and lower die, mold core is equipped in the middle part of the lower die and periphery is equipped with and is used for the pre- clamping flange for clamping and processing plank, mold core is equipped in the middle part of the upper mold and periphery is equipped with and is used for the pre- clamping loose piece for clamping and processing plank；The clamping flange is equipped with the groove for being used for increasing grip friction power, and the clamping loose piece is fixed in upper mold by the spring that border is evenly arranged and which is provided with the protrusion for increasing grip friction power, and the protrusion corresponds occlusion with groove.The utility model prevents from sub- Gree plate from sliding in mold process walking, and improves product appearance quality, reduces product rejection rate.
Description
Technical field
The utility model is related to hot pressing die technical fields, and in particular to a kind of hot pressing die with precompressed flange.
Background technology
Convenience store's lamp box lamp housing generally carries out hot forming using sub- Gree plate；Processing method is usually by the Asia after heating
Gree plate is put into hot pressing die, and sub- Gree plate is pressed into required shape by the molding of hot pressing die upper/lower die.In this process
In since sub- Gree plate is in upper/lower die clamping process, the sliding of sub- Gree plate can be caused to walk, formed product surface is caused to hold
Easily there is phenomena such as orange peel, product surface quality is poor, and it is unqualified to further result in product appearance.
Utility model content
The purpose of this utility model is to solve above-mentioned deficiency, provides a kind of hot pressing die with precompressed flange.
To achieve the above object, the technical solution of the utility model is：A kind of hot pressing die with precompressed flange,
Mold core is equipped with including upper die and lower die, in the middle part of the lower die and periphery is equipped with and is used for the pre- clamping flange for clamping and processing plank, it is described
Mold core is equipped in the middle part of upper mold and periphery is equipped with and is used for the pre- clamping loose piece for clamping and processing plank；The clamping flange, which is equipped with, to be used for
Increase the groove of grip friction power, the clamping loose piece is fixed in upper mold and which is provided with by the spring that border is evenly arranged
For increasing the protrusion of grip friction power, the protrusion corresponds occlusion with groove.
Further, fixed spring center is equipped with and tenses rope between the clamping loose piece and upper mold.
Further, the groove, protrusion are equipped with the pattern draft that inclination angle is 15 °.
Further, the clamping loose piece is quadro frame structure integral arrangement in upper mold.
Further, the minimum point for clamping minimum point raised on loose piece and being less than upper mould core.
Further, the groove, the equal step-by-step arrangement of protrusion.
The utility model in upper mold in clamping process by clamping loose piece with the clamping flange in lower die in spring pressure
Lower carry out precompressed is engaged the sub- Gree plate being located therein with groove by protrusion, prevents sub- Gree plate from being slid in mold process
It walks, avoids surface and defect occur, improve product appearance quality, reduce product rejection rate.
Description of the drawings：
Fig. 1 is the cross-sectional view of the utility model.
Fig. 2 is the positive structure diagram of the utility model.
Specific embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out

The every other embodiment obtained, shall fall within the protection scope of the present invention.
As shown in Figures 1 and 2, a kind of hot pressing die with precompressed flange, a kind of hot pressing die with precompressed flange,
Including upper mold 1, lower die 2,2 middle part of lower die is equipped with mold core and periphery is equipped with and is used for the pre- clamping flange for clamping and processing plank
21,1 middle part of upper mold is equipped with mold core and periphery is equipped with and is used for the pre- clamping loose piece 11 for clamping and processing plank；The clamping flange
21 are equipped with the groove 22 for being used for increasing grip friction power, and the spring 12 that the clamping loose piece 11 is evenly arranged by border is fixed
In upper mold and protrusion 13 for increasing grip friction power is which is provided with, described raised 13 correspond occlusion with groove 22.
Further, fixed 12 center of spring is equipped with and tenses rope 14 between the clamping loose piece 11 and upper mold 1.
Further, the groove 22, protrusion 13 are equipped with the pattern draft that inclination angle is 15 °.
Further, the clamping loose piece 11 is quadro frame structure integral arrangement in upper mold 1.
Further, the minimum point for clamping protrusion 13 on loose piece 11 is less than the minimum point of 1 mold core of upper mold.
Further, the groove 22, raised 13 equal step-by-step arrangements.
The utility model in upper mold in clamping process by clamping loose piece with the clamping flange in lower die in spring pressure
Lower carry out precompressed is engaged the sub- Gree plate being located therein with groove by protrusion, prevents sub- Gree plate from being slid in mold process
It walks, avoids surface and defect occur, improve product appearance quality, reduce product rejection rate.
It is obvious to a person skilled in the art that the utility model is not limited to the details of above-mentioned exemplary embodiment, and
And in the case of the spirit or essential attributes without departing substantially from the utility model, it can realize that this practicality is new in other specific forms
