Description
Technical field
The utility model is related to fixed structure technical fields, and in particular to a kind of fixed structure being easily changed letter stencil.
Background technology
The structure of the fixed letter stencil of tradition, as shown in Figure 1, the reverse side screw in letter stencil is connect with shaping mould.On the market,
A kind of thermoformed article often has many clients, the trade mark of each client is different, so a secondary mould in actual production
Just there are many different letter stencils for tool, this relates to the replacement problem of letter stencil, and traditional the step of replacing letter stencil is very cumbersome, time-consuming
Arduously.It first has to gas circuit that all devices are connect with shaping mould, water route pipe to dismantle；Second whole secondary shaping mould is from equipment
It removes；Third is numerous cavities（General one secondary mold has 12 or so cavities）It is removed from bottom plate one by one；4th wants
Remove the letter stencil on each cavity；5th loads onto shaping mould new letter stencil, then shaping mould dress plus bottom plate, then at
Pattern reinstalls equipment, and connecting line could finally produce.So the letter stencil for changing a secondary mold may need one day time, effect
Rate is low, this problems demand solves.
Utility model content
In view of the shortcomings of the prior art, the utility model provides a kind of fixed structure being easily changed letter stencil, structure profit
Letter stencil is fixed in molding concave die from letter stencil side with the letter stencil lock-screw with the letter stencil lock-screw conical surface, there is structure
It is simple and convenient to operate, the fireballing advantage of letter stencil replacement, greatly improves production efficiency.
To realize that purpose of utility model, the utility model use following technical scheme：
A kind of fixed structure being easily changed letter stencil, including molding concave die, molding concave die bottom plate, letter stencil and letter stencil locking screw
Nail, the molding concave die are connect with molding concave die bottom plate by cavity plate trip bolt, and the letter stencil side is equipped with groove, described recessed
Slot is equipped with the groove conical surface, and the letter stencil is placed in molding concave die and is fixed by letter stencil lock-screw, the letter stencil lock-screw
One end is equipped with the letter stencil lock-screw conical surface, and the letter stencil lock-screw conical surface matches with the groove conical surface, and letter stencil lock-screw is arranged
The purpose of the conical surface is so that the bottom surface of letter stencil is preferably bonded with molding concave die by the upward thrust of the conical surface.
Preferably, the groove conical surface angle with horizontal plane is 45 degree.
Preferably, the letter stencil lock-screw shares two.
Preferably, the unilateral gap of the letter stencil and molding concave die is 0.1 ~ 0.2mm, and letter stencil is enable easily to fall off and put into
Without damaging letter stencil.
Operation principle：
When needing replacing letter stencil, it is not required to dismounting mold, only mold need to be opened, hold letter stencil on the other hand, unscrew letter stencil on the other hand
Lock-screw is freely fallen down until letter stencil, and one piece of new letter stencil is then taken to put into molding concave die, and another hand screws letter stencil locking
Screw, until the letter stencil lock-screw conical surface and the groove conical surface are held out against, whole process is very simple and practical, a whole secondary mold
It can all be solved as long as or so half an hour, greatly improve production efficiency.
The utility model has the beneficial effects that：The utility model provides a kind of fixed structure being easily changed letter stencil, should
Structure utilizes the letter stencil lock-screw with the letter stencil lock-screw conical surface that letter stencil is fixed in molding concave die from letter stencil side, has
There is simple in structure, easy to operate, letter stencil to replace fireballing advantage, greatly improves production efficiency.
Description of the drawings
Fig. 1 is a kind of structural schematic diagram of the structure of existing fixed letter stencil；
Fig. 2 is a kind of structural schematic diagram of the utility model；
Fig. 3 is a kind of partial enlarged view at the utility model further groove conical surface；
In figure：1, molding concave die, 2, molding concave die bottom plate, 3, letter stencil, 4, letter stencil lock-screw, 5, cavity plate trip bolt,
6, the groove conical surface.
Specific implementation mode
Below by specific embodiment, and in conjunction with attached drawing, the technical solution of the utility model work is further specifically retouched
It states：
Embodiment：As shown in Fig. 2, a kind of fixed structure being easily changed letter stencil, including molding concave die 1, molding concave die
Bottom plate 2, letter stencil 3 and letter stencil lock-screw 4, the molding concave die are connect with molding concave die bottom plate by cavity plate trip bolt 5, institute
It states letter stencil side and is equipped with groove, the groove is equipped with the groove conical surface 6, and the letter stencil is placed in molding concave die and is locked by letter stencil
Screw is fixed, and letter stencil lock-screw one end is equipped with the letter stencil lock-screw conical surface, the letter stencil lock-screw conical surface and groove
The conical surface matches, and the purpose of the setting letter stencil lock-screw conical surface is to keep the bottom surface of letter stencil and molding recessed by the upward thrust of the conical surface
Mould is preferably bonded, and groove conical surface angle with horizontal plane is 45 degree, and letter stencil lock-screw shares two, letter stencil and molding concave die
Unilateral gap is 0.1 ~ 0.2mm, and letter stencil is enable easily to fall off and put into without damaging letter stencil.
This is easily changed the fixed structure of letter stencil when needing replacing letter stencil, is not required to dismounting mold, only need to open mold, and one
Hand rest lives letter stencil, unscrews letter stencil lock-screw on the other hand until letter stencil is freely fallen down, it is recessed then to put into molding by one piece of new letter stencil
Mould, another hand screw letter stencil lock-screw, and until the letter stencil lock-screw conical surface and the groove conical surface are held out against, whole process is non-
Normal is simple and practical, as long as can all be solved once or so whole secondary mold half an hour, greatly improves production efficiency.
