Abstract
The utility model relates to a mould, in particular to a mould for encapsulating polyurethane. The mould is characterized in that: air exhaust holes (2) are vertically and horizontally distributed on the lower surface of a template (1) at intervals in a matrix way; and gridded budges (5) are arranged on the upper surface of the template (1). The diameter of each air exhaust hole (2) is in a range of 1+/-0.15 mm. A de-molding ejection rod (4) is arranged at one side of the template (1). The mould for encapsulating the polyurethane has the advantages that air bubbles generated in a foaming process can be effectively discharged in time so that the encapsulated surface is clean and artistic and is easy to de-mold.
Description
Technical field
The utility model relates to a kind of mould, particularly a kind of mould that is used for the polyurethane embedding.
Background technology
Polyurethane elastomer is good because of its insulation, water absorption rate is low, shock absorption good,, no corrosiveness bonding firmly to materials such as metals; And low, the good fluidity of viscosity before solidifying, do not contain solvent, easy to operate, be difficult for producing bubble, can operate at normal temperatures and solidify rapidly, be desirable electronic encapsulation material.In the electronic component use; It is heated the back and electronic component expand together, during cooling and electronic component shrink together, can not form the gap in insulator interface; Play insulation, waterproof and dustproof, shockproof and fixation, guarantee that electronic component and electrical equipment normally move.But polyurethane exists in solidification process and is prone to produce great amount of bubbles and the problem that is difficult for the demoulding, if these bubbles fail in time to discharge, not only influences the presentation quality of product, the more important thing is the electric property and the mechanical performance that influence product.
Summary of the invention
In order to overcome easy bubble and the difficult problem of the demoulding of producing in surface that existing polyurethane embedding occurs; The utility model technology provides a kind of can discharge the mould that is used for the polyurethane embedding that produces bubble in the foaming process timely and effectively, can make the embedding neat and artistic and easy demoulding in surface.
The technical scheme of the utility model is: a kind of mould that is used for the polyurethane embedding is provided, it is characterized in that: below template, be intervally distributed with steam vent in length and breadth with matrix-style, and protruding for gridding on template.
The diameter of described steam vent is in 1mm ± 0.15.
One side of described template has a demoulding push rod.
The utility model has the advantages that: the bubble that produces in the time of in the embedding process, discharging foaming timely and effectively, can also make embedding surface neat appearance, and mould structure is simple to operation.
Below in conjunction with accompanying drawing the utility model is further specified.
Description of drawings
Figure 1A is the front view of the utility model example structure;
Figure 1B is gridding bulge-structure (partial enlarged drawing of Figure 1A) figure;
Fig. 2 is the upward view of Figure 1A.
Among the figure: 1. template, 2. steam vent, 3. handle, 4. demoulding push rod, 5. gridding is protruding.
The specific embodiment
Like Figure 1A, Figure 1B and shown in Figure 2, a kind of mould that is used for the polyurethane embedding is intervally distributed with steam vent 2 at the lower surface of template 1 with matrix-style in length and breadth, and the diameter of steam vent 2 is 1mm ± 0.15.A pair of handle 3 is arranged on the template 1, make carrying, convenient to operation.Upper surface in template 1 is gridding protruding 5; There is a demoulding push rod 4 on the right side, and shown in Figure 1B, the bubble that polyurethane produces when foaming can flow to steam vent 2 along gridding protruding 5; And then in time discharge, can be to the quality and any influence of generation attractive in appearance on embedding surface.During embedding with the upper surface of template 1 as the embedding contact-making surface, embedding finishes the back, and only need turn right side demoulding push rod 4 can easily realize the demoulding.The discharge that protruding 5 designs of gridding not only help bubble can also make the embedding surface aesthetic clean and tidy.
Claims (3)
1. mould that is used for the polyurethane embedding, it is characterized in that: the lower surface in template (1) is intervally distributed with steam vent (2) in length and breadth with matrix-style, is gridding protruding (5) at the upper surface of template (1).
2. a kind of mould that is used for the polyurethane embedding according to claim 1 is characterized in that: the diameter of described steam vent (2) is in 1mm ± 0.15.
3. a kind of mould that is used for the polyurethane embedding according to claim 1 is characterized in that: a side of described template (1) has a demoulding push rod (4).
