Description
Technical field
The utility model relates to hot pressing die, particularly relates to a kind of product surface without the hot pressing die ejecting bar vestige.
Background technology
The manufacture of moulded parts be by starting material in sealed material chamber (the closed die cavity that the structure mode that upper male mould and lower cavity die adopt running fit or frame directly to be pressed is formed) through High Temperature High Pressure and curing molding in the regular hour. In traditional mode of production mode, due to the impact of ejection resistance (package power that the frictional force of the molded surface in plastics and mold releasability direction and plastic shrink are formed), cause adopting the mode ejecting bar or pushing plate, force top pushing product, it is achieved goods are de-from material chamber to be taken out. Ejecting structure by middle backing plate, push rod, the solid plate in top, top push pedal, mould pin, eject six parts such as guiding parts and form, structure is more complicated, in prepared by the mould of macrostructure part, adopt said structure, the requirement of the processing of mould, assembling precision and mould stiffness by itself is higher. Especially when processing the big elongated class section bar component of long-width ratio, its course of processing is easily out of shape, processing units and complete processing and mold material is required higher, causes die manufacturing cost very high; Products appearance aspect, can only design at product surface because push rod ejects position, ejects vestige so can stay on surface after producing, affect using function and goods attractive in appearance.
Practical novel content
The technical assignment of technical problem to be solved in the utility model and proposition is improved prior art, the hot pressing die of a kind of product surface without ejecting bar vestige is provided, solving the traditional hot pressing die in current technology adopts ejection system top to release the goods that curing molding is good, can stay on the surface of goods and eject vestige, and easily cause product deformation, processing units is required high, the problem that die manufacturing cost is high.
For solving above technical problem, the technical solution of the utility model is:
A kind of product surface is without the hot pressing die ejecting bar vestige, comprise punch and die, it is characterized in that, described punch adopts together with the upper and lower split of running fit with die, forms closed die cavity between the two, and described die adopts unitized construction to comprise side template and end template, the end face both sides of end template arrange side template and are combined to form groove, forming, in male bottom insertion groove, the die cavity closed, punch is arranged on upper mounted plate, and end template is arranged on lower retaining plate.
Product surface described in the utility model simplifies mould structure without the hot pressing die ejecting bar vestige, overcome goods ejection resistance in manufacture process, achieve goods without the push rod demoulding, ensure the visual appearance of goods, without ejecting vestige, reduce post-processed workload, it is to increase goods aesthetic property, causes the situation of product deformation when also there will not be push rod top to push away. The utility model adopts the die of unitized construction, make goods after hot pressing is shaping by separately punch and die and by the die of split separately, just the light demoulding can be realized, without the need to re-using ejector rod mechanism, simplify mould structure, reduce manufacture difficulty and the cost of manufacture of mould to a great extent.
Further, described die adopts Side Template and punch, side template and end template split to form closed die cavity in wherein one end of length direction. Die described in the utility model adopts the structure of multi-direction splicing, and handiness is good, improves the convenience of the demoulding further, it is ensured that in knockout course, goods there will not be the situation blocked, and avoids product deformation, ensures the scantlings of the structure precision of goods.
Further, the end face of described Side Template near die cavity side is scarp, plays the effect of guiding split, simultaneously conveniently stripped, is convenient to goods and deviates from.
Further, described die is connected with punch by block at the other end of length direction and makes to form closed die cavity between punch and die, the groove that punch coordinates with block with setting on end template, the utility model utilizes block to ensure the running fit of high precision between punch and die, die cavity is made to have size accurately, improve the formed precision of goods, thus improve the quality of goods.
Further, the demoulding gradient of described punch and die adopt 1 �㡫9 �� 30 ' conveniently stripped, ensure the size high precision of goods simultaneously.
Compared with prior art, the utility model advantage is:
Product surface described in the utility model adopts the mould of built-up type without the hot pressing die ejecting bar vestige, it is not necessary to throwing mechanism just can realize the demoulding, and ensures the size high precision of goods, simplifies mould structure, reduces manufacture difficulty and the cost of manufacture of mould; Product surface does not eject vestige, effectively reduces the workload of post-processed, it is ensured that goods are attractive in appearance and the market competitiveness;
The utility model structure is simple, and convenient for production, production efficiency height, is hot pressed into molded dimension precision height.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the left view cross-sectional view of Fig. 1.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that described embodiment is only the utility model part embodiment, instead of whole embodiments. Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
