Abstract

The utility model provides a mobile phone shell hot melting jig with positioning and limiting functions, which comprises a jig upper die and a jig lower die, wherein four corners of the jig upper die are provided with convex pillars protruding out of the inner lateral surface of the jig upper die; four corners of the inner lateral surface of the jig lower die are provided with grooves clamping with the convex pillars; the inner lateral surface of the jig lower die is also provided with a limit pillar with a certain height; and the convex pillars of the jig upper die are buckled outside the grooves of the jig lower die. The mobile phone shell hot melting jig has simple and practical structure. The problem that a product is crushed by a gap generated due to miss matching of the upper and lower dies or excessively tightly or loosely closed dies can be solved. The mobile phone shell hot melting jig has wide popularization and application prospect.

Description

Phone housing hot melt tool with location and limit function

Technical field

The utility model relates to a kind of tool, and especially a kind of phone housing hot melt tool with location and limit function is a kind of mobile phone plastic shell and bonding device of five metals of making fast, belongs to industrial tool technical field.

Background technology

At present the mobile phone industry decorative appearance adopts five metals to add the combined mode of plastic cement more, and this kind structure majority is used the thermoplasticity curing process, correspondingly will adopt the hot melt tool.General hot melt tool is made up of two patrixes and a counterdie, the locate mode of upper and lower mould adopts wedge type block location in guide pillar or the mould, the coefficient of heat conduction because of upper and lower mould during matched moulds is inconsistent, behind the patrix expanded by heating, whole cavity dimension and detent mechanism can produce deviation, cause five metals and plastic cement on the product to solidify generation gap, back or gap inequality at hot melt, patrix cavity dimension deviation weighs the product phenomenon wounded simultaneously.Another remarkable shortcoming of general hot melt tool mould does not have limit function exactly, and upper and lower mould closes and tightly relies on the cylinder action fully, and the welding effect of PUR is bad in the time of will fashion, needs repeatedly adjustment fuse machine.

Summary of the invention

The utility model application promptly is the above-mentioned defective that exists in the present phone housing hot melt tool, and providing a kind of can position the upper and lower mould of hot melt tool, and the height during to hot melt tool matched moulds carries out spacing mobile phone hot melt tool.

Specifically, phone housing hot melt tool with location and limit function described in the utility model, it is characterized in that: described hot melt tool comprises to be touched on the tool and the tool counterdie, wherein be provided with and protrude from the projection of touching medial surface on the tool at four angles of touching on the tool, four angles of tool counterdie medial surface are provided with the groove with the mutual clamping of projection, and the medial surface of tool counterdie also is provided with the limited post with certain altitude.

Described phone housing hot melt tool with location and limit function, it is characterized in that: the number of described limited post is more than one.

Described phone housing hot melt tool with location and limit function, it is characterized in that: the projection of touching on the described tool is buckled in the outside of tool counterdie groove.

Phone housing hot melt tool with location and limit function described in the utility model has following advantage:

1, detent mechanism guide pillar or the wedge type block with hot melt tool mould inside changes outside locate mode into, solves because of thermal expansion causes deviations, and then causes the die cavity dislocation;

2, in tool, set up limited post, the height of limited post calculates according to product design height dimension and upper and lower mould mould-closing stroke, solved this technology because of the upper and lower mould mismatch,, weighed the problem of product wounded perhaps because of matched moulds tension and the loose excessively gap that is produced;

3, the tool after the process repacking is used for hot melting process, and product can be done drop test again after placing 48 hours under negative 40 degrees centigrade the low temperature environment, the unobvious cracking of five metals and plastic cement.

Fig. 1 is the structural representation with phone housing hot melt tool of location and limit function described in the utility model;

Fig. 2 is the cross-sectional view with phone housing hot melt tool of location and limit function described in the utility model;

Fig. 3 is the local structure for amplifying schematic diagram of section with phone housing hot melt tool of location and limit function described in the utility model;

Wherein, 1 for touching on the tool, 2 being limited post for groove, 21 for projection, 20 for plastic parts, 10 for handware, 4 for tool counterdie, 3.

The specific embodiment

Below in conjunction with accompanying drawing; phone housing hot melt tool with location and limit function described in the utility model is described; purpose is better to understand technology contents described in the utility model for the public; rather than to the restriction of described technology contents; in fact; in the spiritual essence of invention of the present utility model,, comprise the increase and decrease of corresponding component and replace all within the utility model technical scheme required for protection the improvement of described structure.

As shown in Figure 1, phone housing hot melt tool with location and limit function described in the utility model, comprise and touch 1 and tool counterdie 2 on the tool, touch on the tool 1 with the tool counterdie about in the of 2 the side relative, handware 3 and plastic parts 4 be placed on touch on the tool 1 and tool counterdie 2 between, the upper and lower mould of tool fastens and suppresses; Wherein be provided with and protrude from the projection 10 of touching 1 medial surface on the tool at four angles of touching 1 on the tool, four angles of tool counterdie 2 medial surfaces are provided with the groove 20 with projection 10 mutual clampings, the medial surface of tool counterdie 2 also is provided with the limited post 21 with certain altitude, as seen from the figure, the number of described limited post 21 is more than one, is 2 in the present embodiment; As preferred embodiment, touch the outside that 1 projection 10 is buckled in tool counterdie 2 grooves 20 on the described tool.

This phone housing hot melt tool is when carrying out work, shown in Fig. 2 and 3, touch on the tool 1 and tool counterdie 2 handware and the plastic parts drawn close phone housing push, the projection 10 of touching 1 four angles on the tool is connected to the outside of the groove 20 at 2 four angles of tool counterdie, the upper and lower mould butt joint closely, and be convenient to observe, also be provided with the limited post 21 that several (in the present embodiment being 2) have certain altitude in the inboard of tool counterdie 2, make on the tool, gap between the counterdie arrives predetermined requirement, to guarantee that phone housing in pressing process, is unlikely to the dislocation that causes because of tension, situations such as cracking.

Phone housing hot melt tool with location and limit function described in the utility model, simple and practical, can solve because of the upper and lower mould mismatch, perhaps because of matched moulds tension and the loose excessively gap that is produced, weigh the problem of product wounded, have broad prospect for its application.
