Abstract
The invention discloses a pressure bearing cushion block structure for a needle valve type hot runner system. The pressure bearing cushion block structure comprises a spreader plate, a pressure bearing cushion and a formwork, also comprises an upper pressure bearing cushion, wherein the upper pressure bearing cushion is a circular structure member, the inner hole of the circular structure member is a hanging needle valve hole, and two screw counter bores are symmetrically arranged in two sides of the hanging needle valve hole; the upper surface of the upper pressure bearing cushion is embedded into the formwork, and the lower surface of the upper pressure bearing cushion is correspondingly connected with the pressure bearing cushion. The pressure bearing cushion block structure for the needle valve type hot runner system solves the problems of smaller contact area of the pressure bearing cushion and the formwork and gum leakage because the pressure bearing cushion is easily embedded into the formwork in the condition of high temperature in the prior art.
Description
Technical field
The present invention relates to injection molding apparatus, relate in particular to a kind of needle valve TOP-TIP with pressure-bearing cushion block structure, this pressure-bearing cushion block structure is used to be installed in and plays heat insulation, anti-deformation effect on the injection moulding hot runner flow distribution plate.
Background technology
As shown in Figure 1, the upper surface of injection moulding hot runner flow distribution plate 1 also is equipped with and is used to support and the fixing pressure-bearing cushion block 2 of the relative position of flow distribution plate 1 except the main burner (not shown) is installed, and pressure-bearing cushion block 2 directly contacts with template 3.When injection moulding hot runner flow distribution plate is used for injection moulding; Nozzle on being installed in injection moulding hot runner flow distribution plate will be with template contacts, and its pressure-bearing cushion block that is positioned at nozzle one side also can directly contact with template surface inevitably, because injection moulding hot runner flow distribution plate is in the condition of high temperature of heating when work; And template surface is the normal temperature state; When the pressure-bearing cushion block on the flow distribution plate contacts with template surface, have heat and be delivered to template surface from flow distribution plate through the pressure-bearing cushion block, this can cause the thermal loss of flow distribution plate on the one hand; Seriously can cause cold burden and ramming material, influence normal injection moulding; If after having great amount of heat to be delivered to template surface on the other hand; Because the hardness of template is not high, under the hot operation state, mould material is softer; Because pressure-bearing cushion block and template contact area are very little; The flow distribution plate pressure pad piece of upwards bearing responsibility that at high temperature can expand, then the pressure-bearing cushion block very easily falls in the progressive die plate and goes, and leaks glue easily.
Therefore, how addressing the above problem, is the content that the present invention will study.
Summary of the invention
The present invention provides a kind of needle valve TOP-TIP with pressure-bearing cushion block structure, and its purpose mainly is that to solve in the prior art pressure-bearing cushion block less with the template contact-making surface, under high-temperature condition, in the sunken easily progressive die plate of pressure-bearing cushion block, causes the Lou problem of glue.
For achieving the above object, the technical scheme that the present invention adopts is: a kind of needle valve TOP-TIP comprises flow distribution plate, pressure-bearing cushion block and template with pressure-bearing cushion block structure; Also comprise cushion block on the pressure-bearing, cushion block is a cirque structure spare on this pressure-bearing, and its endoporus is the needle via hole, and the bilateral symmetry of this needle via hole is provided with two screw counterbores; The upper surface of cushion block is embedded in the template on the said pressure-bearing, its lower surface and the corresponding connection of said pressure-bearing cushion block.
Related content in the technique scheme is explained as follows:
1, in the such scheme, the ring periphery of cushion block is provided with a ring annular groove on the said pressure-bearing.
2, in the such scheme, cushion block is through Overheating Treatment on the said pressure-bearing, and hardness uprises.
The utilization of art scheme, the present invention compared with prior art has advantage:
1, because the present invention adopts that the upper surface of cushion block is embedded in the template on the pressure-bearing, make the contact area increase of cushion block and template on the pressure-bearing, and cushion block is through Overheating Treatment on the pressure-bearing, hardness uprises.Contact with the lower surface of cushion block on the upper surface of the pressure-bearing cushion block of flow distribution plate contact and the pressure-bearing and to be connected; After flow distribution plate high temperature expands; Significantly reduced the heat on the flow distribution plate and be delivered to the possibility on the mould through the pressure-bearing cushion block; Mould is not yielding, and the pressure-bearing cushion block can not fall in the progressive die plate yet and go, and can effectively solve the Lou problem of glue.
2, the present invention is simple in structure, practical.
Description of drawings
Accompanying drawing 1 is a pressure-bearing cushion block fit structure schematic cross-section in the prior art;
Accompanying drawing 2 is used the structural section sketch map for the present invention.
In the above accompanying drawing: 1, flow distribution plate; 2, pressure-bearing pressure pad piece; 3, template; 4, cushion block on the pressure-bearing; 5, needle via hole; 6, screw counterbore.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further described:
Embodiment:
As shown in Figure 2, a kind of needle valve TOP-TIP comprises flow distribution plate 1, pressure-bearing cushion block 2 and template 3 with pressure-bearing cushion block structure; Also comprise cushion block 4 on the pressure-bearing, cushion block 4 is a cirque structure spare on this pressure-bearing, and its endoporus is a needle via hole 5, and the bilateral symmetry of this needle via hole 5 is provided with two screw counterbores 6; An end of cushion block 4 is embedded in the template 3 on the said pressure-bearing, its other end and said pressure-bearing cushion block 2 corresponding connections.
The ring periphery of cushion block 4 is provided with a ring annular groove on the said pressure-bearing.
The upper surface of cushion block 4 is embedded in the template 3 on the pressure-bearing, make that the contact area of cushion block 4 and template 3 increases on the pressure-bearing, and cushion block 4 is through Overheating Treatment on the pressure-bearing, and hardness uprises.Contact with the lower surface of cushion block 4 on the upper surface of the pressure-bearing cushion block 2 of flow distribution plate 1 contact and the pressure-bearing and to be connected; After flow distribution plate 1 high temperature expands; The heat that has significantly reduced on the flow distribution plate 1 is delivered to the possibility on the mould 3 through pressure-bearing cushion block 2; Mould 3 is not yielding, and pressure-bearing cushion block 2 can not fall in the progressive die plate yet and go, and can effectively solve the Lou problem of glue.
The foregoing description only is explanation technical conceive of the present invention and characteristics, and its purpose is to let the personage who is familiar with this technology can understand content of the present invention and enforcement according to this, can not limit protection scope of the present invention with this.All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed within protection scope of the present invention.
