Description

A kind of device of eliminating injecting products distortion

Technical field

The utility model relates to a kind of deformation of products device of eliminating, particularly a kind of device of eliminating injecting products distortion.

Background technology

Handset front case is because many reasons can produce distortion after injection moulding, and mobile phone shell before use, need to be eliminated correction to its distortion conventionally, can make like this phone housing in use avoid occurring that between parts, gap is excessive, screen cracking, the quality problems such as breakage.And eliminating in the process of distortion, be generally to coordinate the method for bench drill to complete elimination with locating piece, its weak point is that pressure point is single, poor stability, and the bad guarantee of product quality, output yield is low.

Summary of the invention

In view of the deficiency of prior art existence, the utility model provides a kind of device of eliminating deformation of products, the technical scheme adopting is, a kind of device of eliminating injecting products distortion, comprise top board, guide pin bushing, screw, pad, guide pillar, spring, contiguous block, depression bar, top nut, depression bar fixed block, lower nut, pressure head, locating piece, base plate, it is characterized in that: center, base plate upper surface stationary positioned piece, guide pillar is fixed in both sides, spring housing is contained on guide pillar and center line overlaps, four depression bars are respectively by top nut and lower nut rectangular vertical being fixed on depression bar fixed block apart, four pressure heads are individually fixed in the bottom of depression bar, fixed block is by the parallel lower surface that is fixed on top board of contiguous block, the guide pin bushing that is fixed on top board inserts in guide pillar, screw, pad is fixed on guide pillar top.

The beneficial effect that the utility model produces is that efficiency is high, good stability, promotes output yield, maintenance and repair conveniently, reduces maintenance cost.

Brief description of the drawings

Fig. 1 is the utility model assembly structure schematic diagram.

Detailed description of the invention

As shown in Figure 1, eliminate the device of injecting products distortion, comprise top board 1, guide pin bushing 2, screw 3, pad 4, guide pillar 5, spring 6, contiguous block 7, depression bar 8, top nut 9, depression bar fixed block 10, lower nut 11, pressure head 12, locating piece 13, base plate 14, base plate 14 center, upper surface stationary positioned pieces 13, guide pillar 5 is fixed in both sides, spring 6 is sleeved on guide pillar 5 and center line overlaps, four depression bars 8 are respectively by top nut 9 and lower nut 11 rectangular vertical being fixed on depression bar fixed block 10 apart, four pressure heads 12 are individually fixed in the bottom of depression bar 8, fixed block 10 is by the parallel lower surface that is fixed on top board 1 of contiguous block 7, the guide pin bushing 4 that is fixed on top board 1 inserts in guide pillar 5, screw 3, pad 4 is fixed on guide pillar top.

When use, package unit is fixed on cold press by pressing plate, to treat that shaping product is placed on device locating piece 13, and start cold press, device pressure head 12 moves down and makes product produce reversible deformation, close cold press, on device pressure head 12, move, take off product, complete the elimination distortion to product, pressure, time, the degree of depth that while eliminating distortion, pressure head 12 presses down, all can be by cold press control.
