Description
Technical field
The utility model is related to injection machine technical field, especially a kind of injection molding machine mold clamping mechanism.
Background technology
Injection machine also known as injection (mo(u)lding) machine or injector.It is that thermoplastic or thermosetting plastics are utilized into plastic shaping
The main former of variously-shaped plastic products is made in mould, is divided into vertical, horizontal, all electric.It is molded function heating modeling
Material, high pressure is applied to molten plastic, is projected it and is full of mold cavity, is typically locked on existing injection machine as shown in Figure 1
Mold mechanism, its mainly include solid plate 1, moving platen 2, tailgate and pull bar 4, mould include cover half 5 and dynamic model 6, the solid plate 1,
The mounting surface of moving platen 2, cover half 5 and dynamic model 6 is plane, between moving platen 2 and dynamic model 6 and fixed when clamping mechanism is not locked
It is brought into close contact between template 1 and cover half 5；As shown in Fig. 2 solid plate 1 and moving platen 2 deform after clamp force is set up, this
When mould and template can not be brought into close contact, support of the template to mould only has four points, and the effect of mould of rising in injection makes mould
Gap is produced in die joint 7, causes moulded products to produce the defects such as overlap.
Utility model content
The technical problems to be solved in the utility model is：It is fixed in order to solve clamping mechanism of the prior art after locking
The problem of template and moving platen easily deform, now provides a kind of injection molding machine mold clamping mechanism.
The utility model solves the technical scheme that its technical problem used：A kind of injection molding machine mold clamping mechanism, including draw
Moving platen and solid plate are relatively set with bar, the pull bar, dynamic model and cover half are provided between the moving platen and solid plate,
The moving platen side relative with solid plate is outwardly hemisphere jut.
Hemisphere jut is designed in moving platen and the relative side of solid plate in this programme, when mould does not have tensioner, dynamic model
Plate there is strength to support dynamic model by hemisphere jut thereon, and predeformation occurs for hemisphere jut, and same solid plate passes through it
On hemisphere jut to cover half have strength support, after mould (dynamic model and cover half) tensioner, due to the presence of predeformation, move
It is brought into close contact, is brought into close contact between solid plate and cover half between template and dynamic model, moving platen and solid plate is to the dynamic model between it
Comprehensive support state is in cover half, has prevented the gap produced between dynamic model and cover half at die joint.
Preferably, the outwardly thickness of the hemisphere jut is h, wherein, h span is 0.01-1mm.
Preferably, on the moving platen with respect to solid plate side side outer contour and moving platen on hemisphere jut bottom
The outer contour in face is overlapped, on the solid plate with respect to moving platen side side outer contour and solid plate on hemisphere jut
The outer contour of bottom surface is overlapped.
The beneficial effects of the utility model are：Injection molding machine mold clamping mechanism of the present utility model passes through in moving platen and solid plate
There is provided a predeformation space for upper setting hemisphere jut so that moving platen and solid plate are to dynamic model and cover half comprehensive support, it is ensured that
Die joint between dynamic model and cover half will not produce gap, improve the quality of moulded products, while protecting mould well, improve
The mold use life-span.

Embodiment
The utility model is described in further detail presently in connection with accompanying drawing.These accompanying drawings are simplified schematic diagram,
Only illustrate basic structure of the present utility model in a schematic way, therefore it only shows the composition relevant with the utility model, direction
With can be only used for helping the description to the feature in accompanying drawing with reference to (for example, upper and lower, left and right, etc.).Therefore, not in limit
Detailed description below is used in property meaning processed, and only by appended claims and its equivalents are asked to limit
The scope of the theme of protection.
Embodiment 1
As in Figure 3-5, moving platen 2 is relatively set with a kind of injection molding machine mold clamping mechanism, including pull bar 4, pull bar 4 and fixed
Template 1, is provided with dynamic model 6 and cover half 5 between moving platen 2 and solid plate 1, the side relative with solid plate 1 of moving platen 2 is outside
It is protruding with hemisphere jut 8.
The outwardly thickness of hemisphere jut 8 is h, wherein, h span is 0.01-1mm.
On moving platen 2 with respect on outer contour and the moving platen 2 of the side side of solid plate 1 bottom surface of hemisphere jut 8 it is outer
Contour line is overlapped, the bottom surface of hemisphere jut 8 on the outer contour and solid plate 1 of the side side of relative moving platen 2 on solid plate 1
Outer contour is overlapped.
Injection molding machine mold clamping mechanism difference with the prior art of the present utility model is：Moving platen 2 and solid plate 1 are relative
Hemisphere jut 8 is designed in side, when mould does not have tensioner, and moving platen 2 has had by hemisphere jut 8 thereon to dynamic model 6
Strength is supported, and predeformation occurs for hemisphere jut 8, and same solid plate 1 has strength by hemisphere jut 8 thereon to cover half 5
Support, after mould tensioner, due to the presence of predeformation, is brought into close contact, solid plate 1 and cover half 5 between moving platen 2 and dynamic model 6
Between be brought into close contact, moving platen 2 and solid plate 1 are in comprehensive support state to the dynamic model 6 and cover half 5 between it, have prevented dynamic
The gap produced between mould 6 and cover half 5 at die joint 7.
Above-mentioned clamping mechanism is equally applicable to other moulds.
Above-mentioned is enlightenment according to desirable embodiment of the present utility model, passes through above-mentioned description, relevant staff
Various changes and amendments can be carried out in the range of without departing from this utility model technological thought completely.This practicality
New technical scope is not limited to the content on specification, it is necessary to determine that its is technical according to right
Scope.
