Abstract
The utility model relates to a mold, in particular to a mold with a heating rod. The mold with the heating rod mainly comprises a fixed mold plate, a movable mold plate, a thermocouple, a heating rod and a guide column, wherein the fixed mold plate is connected with a fixed mold insert through a first bolt, and the movable mold plate is connected with a movable mold insert through a second bolt; the heating rod penetrates through the fixed mold plate and the fixed mold insert and is arranged above the central line of the fixed mold insert, and the heating rod and the thermocouple are connected with the fixed mold plate through a bolt. The distance between the heating rod and the forming surface of a mold cavity is 12mm to 14mm, and the guide column penetrates through the fixed mold plate and the movable mold plate and is connected with the fixed mold plate. The heating rod is used for partially heating the mold, so that the defects such as weld marks, wire drawing, material insufficiency, and non-uniform shrinkage caused by the poor mobility of the forming material can be effectively improved.
Description
Technical field
The utility model relates to a kind of mould, more particularly, relates to a kind of mould with heating rod.
Background technology
At present, to requiring mold temperature below 80 ℃ the time, can utilize the waste heat that molten plastic conducts to mould in injection moulding process that mould is heated up.But the poor plastic shaping of flow all requires mould to have higher temperature, to requiring mold temperature will be heated mould when the plastic shaping of 80 ℃, otherwise can affect the mobility of melt, make it be difficult to moulding, simultaneously, also can produce larger Osima jacoti, Osima excavata, cause the plastics internal stress to increase, and plastic weld mark, wire drawing may occur or lack expecting, shrink the defects such as inhomogeneous.
Summary of the invention
The deficiency existed in order to overcome prior art, the utility model purpose is to provide a kind of mould with heating rod.This mould is to utilize heating rod to carry out local heat to mould, can effectively improve because the moulding material poor fluidity causes plastic weld mark, wire drawing or lack expecting, shrink the defects such as inhomogeneous.
In order to realize the foregoing invention purpose, solve the problem existed in prior art, the technical scheme that the utility model is taked is: a kind of mould with heating rod, mainly comprise solid plate, moving platen, electroheat pair, heating rod and guide pillar, described solid plate is connected with the cover half mold insert by the first bolt, and described moving platen is connected with the dynamic model mold insert by the second bolt; Described heating rod runs through solid plate and cover half mold insert, and is positioned at the top of cover half mold insert center line, and with solid plate, is connected by bolt with electroheat pair.
Described heating rod is 12-14mm apart from the height of mold cavity molded surface.
Described guide pillar runs through solid plate and moving platen, and is connected with solid plate.
The utility model beneficial effect is: a kind of mould with heating rod, mainly comprise solid plate, moving platen, electroheat pair, heating rod and guide pillar, described solid plate is connected with the cover half mold insert by the first bolt, and described moving platen is connected with the dynamic model mold insert by the second bolt; Described heating rod runs through solid plate and cover half mold insert, and is positioned at the top of cover half mold insert center line, and with solid plate, is connected by bolt with electroheat pair.Compared with the prior art, the utility model is to utilize heating rod to carry out local heat to mould, can effectively improve because the moulding material poor fluidity causes plastic weld mark, wire drawing or lack expecting, shrink the defects such as inhomogeneous.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure: 1, solid plate, 2, the cover half mold insert, 3, heating rod, 4, plastic, 5, electroheat pair, 6, moving platen, 7, the dynamic model mold insert, 8, guide pillar, the 9, first bolt, the 10, second bolt.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, a kind of mould with heating rod, mainly comprise solid plate 1, moving platen 6, electroheat pair 5, heating rod 3 and guide pillar 8, described solid plate 1 is connected with cover half mold insert 2 by the first bolt 9, and described moving platen 6 is connected with dynamic model mold insert 7 by the second bolt 10; Described heating rod 3 runs through solid plate 1 and cover half mold insert 2, and is positioned at the top of cover half mold insert 2 center lines, and with solid plate 1, is connected by bolt with electroheat pair 5.Described heating rod 3 is 12-14mm apart from the height of mold cavity molded surface, and described guide pillar 8 runs through solid plate 1 and moving platen 6, and is connected with solid plate 1.
The utility model advantage is: heating rod is positioned at the top of cover half mold insert center line, by the mold flow analysis heating rod, apart from the surperficial 13mm of mold cavity forming place, is optimum position, and molding effect is best.When moulding material is filled, heating rod carries out local heat to the mold center position, thus improved material mobility, reach the purpose of improving open defect.
