Abstract
The utility model relates to an injection moulding mould structure. Injection moulding mould structure includes mould and lower mould, goes up the mould and is equipped with the last die cavity that open side down, and the lower mould is equipped with the corresponding lower die cavity of ascending and the last die cavity of opening, lower die cavity or go up the die cavity in be equipped with the elastic cushion who is used for pressing from both sides tight metal insert when the compound die, elastic cushion gives prominence to in the lower surface of the upper surface of lower mould mould on perhaps, before last mould and lower mould compound die, some places the upper surface at elastic cushion metal insert, and another part is unsettled above die cavity down, after last mould and lower mould compound die, go up mould and elastic cushion extrusion metal insert. The utility model discloses utilize elastic cushion's elasticity and resilience, can not damage metal insert or mould by pressure when going up the mould with the lower mould compound die, be not used in specific position when placing metal insert, reduced precision and the defective rate of placing metal insert, improved production efficiency.
Description
Technical field
This utility model relates to injection molding equipment, particularly relates to a kind of injection mold lamps structure。
Background technology
Along with product demand is improved constantly by people, or the demand in some product properties。Multiple materials of traditional handicraft produce the technique assembled again respectively and are insufficient for product demand, so placing the processing technique of metal inserted piece when occurring as soon as injection moulding。
Mould is required higher with mold insert by this technique, and places required precision height, particularly when metal inserted piece less (0.1-1mm) time。If realizing automatically or semi-automatically producing, it is necessary to put into accurate automation equipment, and at the bottom of production efficiency, fraction defective is high。
Utility model content
The purpose of this utility model is in that the defect for overcoming prior art, and provides a kind of injection mold lamps structure, to reduce the requirement to mould, mold insert placement precision, and improves production efficiency, reduces fraction defective。
For achieving the above object, this utility model is by the following technical solutions:
Injection mold lamps structure includes upper die and lower die; upper mould is provided with the upper cavity that Open Side Down; counterdie is provided with the lower mode cavity corresponding with upper cavity of opening upwards; lower mode cavity or upper cavity are provided with for coordinating mould or the elastic cushion of counterdie clamping metal inserted piece when matched moulds, and elastic cushion protrudes from the upper surface of counterdie or the lower surface of upper mould；A metal inserted piece part is placed on elastic cushion upper surface, and another part is suspended on above lower mode cavity。
Further, elastic cushion is silica gel cushion。
Further, elastic cushion embeds and is fixed in lower mode cavity。
Further, after upper mould and counterdie matched moulds, the upper surface of elastic cushion be compressed into in counterdie upper surface approximately the same plane。
Further, elastic cushion embeds and is fixed in upper cavity。
Further, after upper mould and counterdie matched moulds, the lower surface of elastic cushion be compressed into in upper mould lower surface approximately the same plane。
This utility model compared with prior art provides the benefit that:
This utility model utilizes elasticity and the resilience of elastic cushion, will not damage metal inserted piece or mould when upper mould and counterdie matched moulds by pressure, not be used in specific position when placing metal inserted piece, reduces the precision and fraction defective of placing metal inserted piece, improves production efficiency。
Accompanying drawing explanation
Fig. 1 is the cross-sectional schematic before upper mould and the non-matched moulds of counterdie；
Fig. 2 be upper mould with the non-matched moulds of counterdie injection material after cross-sectional schematic。
Detailed description of the invention
In order to more fully understand technology contents of the present utility model, below in conjunction with specific embodiment the technical solution of the utility model it is described further and illustrates。
First embodiment
The concrete structure of this utility model first embodiment is as depicted in figs. 1 and 2。Mould structure of the present utility model can be used for placing in the injection moulding main bodys such as plastic cement, pottery or powder metallurgy 40 the structure processing of metal inserted piece 30。This product includes injection molding main body 40 and the metal inserted piece 30 stretched in main body 40。Add man-hour requirement and place metal inserted piece 30, then matched moulds, then carry out material injection molding and obtain the main body 40 of portion envelops metal inserted piece 30, complete product is taken out in last die sinking。
As it is shown in figure 1, injection mold lamps structure includes mould 11 and counterdie 12。Upper mould 11 is provided with the upper cavity 111 that Open Side Down。Counterdie 12 is provided with the lower mode cavity 121 of opening upwards。Lower mode cavity 121 is corresponding with upper cavity 111, and when matched moulds, lower mode cavity 121 and upper cavity 111 surround die cavity and form main body 40 with injection material。
As depicted in figs. 1 and 2, the elastic cushion 20 for clamping metal inserted piece 30 when matched moulds it is provided with in lower mode cavity 121。Elastic cushion 20 embeds and is fixed in counterdie 12。Elastic cushion 20 protrudes from the upper surface 122 of counterdie 12, and namely the upper surface 21 of elastic cushion 20 is higher than the upper surface 122 of counterdie 12。The length that the width of elastic cushion 20 contacts with elastic cushion 20 more than metal inserted piece 30 so that by mould 11 compress time, metal inserted piece 30 will not contact with the upper surface 122 of counterdie 12, it is to avoid mould or the damage of metal inserted piece 30 occurs。
In first embodiment, elastic cushion 20 is silica gel cushion。In other embodiments, the material of different elastic cushion can according to the difference of material of main part, be selected。
As it is shown in figure 1, before upper mould 11 with counterdie 12 matched moulds, metal inserted piece 30 part is placed on elastic cushion 20 upper surface, and another part is suspended on above lower mode cavity 121。As shown in Figure 2, after upper mould 11 with counterdie 12 matched moulds, upper mould 11 extrudes metal inserted piece 30 with elastic cushion 20, the upper surface 21 of elastic cushion 20 be compressed into in counterdie 12 upper surface 121 approximately the same plane, now just can toward injection material in the die cavity that upper cavity 111 and lower mode cavity 121 surround to form main body 40。
Second embodiment
Second embodiment difference from first embodiment is in that: be provided with the elastic cushion for clamping metal inserted piece when matched moulds in upper cavity；Elastic cushion embeds and is fixed in mould；Elastic cushion protrudes from the lower surface of mould, and namely the lower surface of elastic cushion is higher than the lower surface of upper mould。By in upper to elastic cushion 30 flip vertical in Fig. 1 embedding mould 11, and metal inserted piece 30 is placed directly on the upper surface 122 of counterdie 12, and the position that counterdie 12 is placed original elastic cushion 30 changes entity into, just obtain the sectional structure schematic diagram of the second embodiment。
Set forth above only further illustrate technology contents of the present utility model with embodiment; so that reader is easier to understand; but not representing embodiment of the present utility model and be only limitted to this, any technology done according to this utility model extends or recreation, all by protection of the present utility model。
