Be suitable for the glassware lid mould of automatic production
Technical field
The present invention relates to a kind of glass article, particularly a kind of glassware lid mould belongs to glass article and makes the field.
Background technology
Glass article is used to make glassware; The variation of current social glassware and complicated be the new problem that the glass ware mould industry is faced; From single cup, bowl, the dish that is used to hold article, be seen everywhere in the life to the glassware ornamental that is used to view and admire usefulness.
Along with the widespread use of glassware in life, people are also increasingly high to its requirement, and are when pursuing practicality, also increasingly high to the requirement of profile.Microwave oven pot cover for example; The moulding of pot cover itself is simple relatively; But for attractive in appearance, the section diameter that is used to grip on the pot cover is usually designed to the diameter greater than grip portions and pot cover body junction, and such design brings a difficult problem for the design of corresponding glass article.The common mould that is used to make the glassware lid, the general employing gone up lower open die tool mode, and patrix is an integral body, and counterdie is that two portions separate die sinking.
Under the situation of workman's manual production; When making pot cover as described above, too big problem can not appear in the mode that counterdie two is held, and when die sinking, can according to circumstances artificially adjust; It will be used for large-scale automatic production and then occur die sinking easily and have some setbacks, and scratches problems such as lid.In order to be more suitable for automatic production, glass article also is designed to the mode of three lobe die sinkings sometimes, but this design normally mold integral three open, cause product the moving of position in mould during moulds open easily, thereby product caused damage.
Summary of the invention
The purpose of this invention is to provide a kind of glassware lid Forming Quality that can guarantee and be suitable for the glassware lid mould of mass automatic production again.
Technical scheme of the present invention is such: the glassware lid mould that is suitable for automatic production; It is characterized in that comprising drift, cover plate, upper die and lower die, patrix supporting seat, push rod and base, drift, cover plate, upper die and lower die and push rod constitute the space design of glassware lid, and push rod can be installed in the middle part of base up and downly; The patrix supporting seat is fixedly connected with push rod; Patrix is arranged on the patrix supporting seat, and said counterdie is between push rod and base, and it is divided at least three parts along symmetry centre; The each several part of five equilibrium is movably connected on base, can be when push rod moves up and down slides up and down and is that outwards launch in the axle center with the push rod along base.
In the specific embodiment of the present invention, said cover plate is provided with insulation ring.
Counterdie of the present invention adopts three to open or five equilibrium die sinking mode more; Solve the glassware lid problem that lid scratches in moulding process and be applicable to automatic production; Patrix and product relative position remain unchanged in the time of counterdie die sinking simultaneously, thereby have avoided the die sinking of product complicated part to cause the situation of other part damage.

Embodiment
Below in conjunction with embodiment the present invention is described further.
As shown in Figure 1; Glassware lid mould comprises drift 1, cover plate 2, patrix 3, counterdie 4, patrix supporting seat 5, push rod 6 and base 7; Drift 1, cover plate 2, patrix 3, counterdie 4 and push rod 6 constitute the space design 8 of glassware lid; Push rod 6 can be installed in the middle part of base 7 up and downly, and patrix supporting seat 5 is fixedly connected with push rod 6, and patrix 3 is arranged on the patrix supporting seat 5.
Counterdie 4 as shown in Figure 2 is accomplished the processing back in integral body and is cut into trisection along its symmetry centre through line.In conjunction with Fig. 1, each aliquot of counterdie 4 becomes an integral body between push rod 6 and base 7, and the each several part of five equilibrium is movably connected on base 7, can be when push rod 6 moves up and down slides up and down and is that outwards launch in the axle center with push rod 6 along base 7.
During production; Drift 1 is connected with board through flange; Base 7 is fixed on the board, and frit is inserted space design 8 back punching head 1 and exerted pressure downwards to impel frit by the mold shape moulding, insulation ring 9 is set on the cover plate 2 guarantees the upper and lower mould heat radiation of mould consistence; Guarantee the Forming Quality of product, reduce distortion.
During counterdie 4 die sinkings, upwards lift drift 1, remove cover plate 2 and insulation ring 9; Push rod 6 is by corresponding intrument jack-up on the board; Push rod 6 produces in base 7 and moves upward, and patrix supporting seat 5 moves upward with push rod 6, and this moment, patrix 3 was moved upward by patrix supporting seat 5 jack-up doing equally.Push rod 6 by the process of jack-up in, counterdie 4 upwards slides in base 7, and is that outwards launch in the axle center with push rod 6 progressively; When push rod 6 during upward to big limit position, counterdie 4 each several parts launch fully, make its moulding partly accomplish the demoulding; And since patrix 3 with push rod 6 by jack-up; When therefore counterdie 4 was accomplished die sinking, the relative position of product in patrix 3 do not change, and this makes the relative movement in mould of other parts cause the problem of damage with regard to having been avoided the die sinking of product complicated part.After counterdie 4 die sinkings, product taken out from patrix just can obtain the high finished glass vessel of Forming Quality lid.
The foregoing description does not limit the present invention in any way, and every employing is equal to the technical scheme that replacement or the mode of equivalent transformation obtain and all drops in protection scope of the present invention.
