Abstract
The invention discloses a technique for eliminating deformation of plastic parts, comprising the following steps: (A) the deformation of plastic parts is measured by a plug gauge and plastic parts, the deformation value of which is between 0.15mm and 0.25mm, are selected; (B) the selected plastic parts are put into a heating furnace to be heated and are taken out when the surface temperature of the plastic parts is between 70 DEG C and 80 DEG C; and (C) the plastic parts which are taken out are put into a reforming jig to be reformed for 10-15s. The technique has the advantages of being simple in structure, unnecessary to input a great quantity of manpower and material resources, high in production efficiency and good in stability. The stress of plastic parts is eliminated by external force pressure and the problem of deformation of plastic parts is effectively solved. In addition, after being processed by the technique, the plastic parts do not re-deform, thus the yield of moulded plastic parts is improved.
Description
Technical field
Plastic parts manufacturing technology field of the present invention, particularly a kind of process eliminating plastic parts distortion.
Background technology
Along with the extensive use of plastic parts, plastic parts has multiple molding mode, and wherein comparatively common molding mode is injection mo(u)lding, namely utilizes outer bound pair raw material to heat, make it to reach molten condition, then fused raw material is expelled to the process of particular mold die cavity by injection machine.During shaping die sinking, plastic parts is by cold events, and the thinner elements constrict degree in position be more significantly, causes plastic parts inner generation stress, causes plastic parts to be out of shape.The method of existing elimination plastic parts distortion takes rubber hammer to beat distortion position gently, but this method can have certain damage to parts surface on the one hand, and on the other hand, efficiency is low, and achievement is not remarkable, waste of manpower cost.
Summary of the invention
Object of the present invention, by a kind of process eliminating plastic parts distortion, efficiently, fast, stably improves the problem on deformation of plastic part.
In order to solve the problems of the technologies described above, the present invention takes following technical scheme:
Eliminate a process for plastic parts distortion, have following steps: A, measure the deflection of plastic parts with feeler gauge, select the plastic parts of deflection between 0.15-0.25mm; B, the plastic parts selected is put into heating furnace heat, take out when plastic rubber member surface temperature reaches between 70-80 DEG C; C, the plastic parts of taking-up is put into shaping tool shaping, training time is 10-15S.
Described shaping tool comprises base, the support be fixed on base, vertically rack-mount cylinder, be arranged on the moving platen on the piston rod of cylinder and the master mold be arranged on base and starting switch.
The central authorities of described moving platen have been provided with the location silica gel block of fixing plastic parts effect, and the periphery of moving platen is provided with vertical stud, stud are provided with the shaping silicagel column of band internal screw thread plastic parts being carried out to shaping.
Described master mold is provided with vertical stud, stud has been provided with the support silicagel column of the band internal screw thread supporting plastic parts effect.
Described starting switch has two, is installed on base both sides.
Compared with prior art, the present invention is without the need to dropping into a large amount of manpower and materials, and production efficiency is high, good stability, eliminates plastic parts stress by external force pressure, efficiently solves the problems such as plastic parts distortion, and after this PROCESS FOR TREATMENT, can not again be out of shape, improve the yields of shaping rear plastic parts.
Accompanying drawing explanation
Fig. 1 is the main TV structure schematic diagram of shaping tool in the present invention;
Fig. 2 is the left view of Fig. 1.
Number in the figure is depicted as: 1-cylinder, 2-support, 3-moving platen, 4-plastic parts, 5-master mold, 6-base, 7-starting switch.
Detailed description of the invention
For the ease of the understanding of those skilled in the art, below in conjunction with the drawings and specific embodiments, the present invention is further described:
Please refer to Fig. 1 and Fig. 2, the process that the present invention eliminates plastic parts distortion has the following steps:
A, use feeler gauge carry out deflection inspection to plastic parts, and the plastic parts of deflection between 0.15-0.25mm is picked out, and be out of shape necessity that too little nothing carries out shaping, and the too large the present invention that utilizes of distortion cannot produce a desired effect.
B, select plastic parts is put on the conveyer belt of UV stove, adjust the speed of conveyer belt, allow plastic parts from UV stove out time its surface temperature can reach between 70-80 DEG C, in this temperature range, the plasticity of plastic parts can be increased under the prerequisite not affecting the outward appearance of plastic parts, structure.
C, a kind of shaping tool to be used in this step, this shaping tool comprises base 6, the support 2 be fixed on base 6, the cylinder 1 be arranged on support 2, vertically be arranged on the moving platen 3 on the piston rod of cylinder 1 and the master mold 5 be arranged on base 6 and starting switch 7.Moving platen 3 is provided with location silica gel block 3B and shaping silicagel column 3A, master mold 5 is equipped with and supports silicagel column 5A, and shaping silicagel column 3A can adjust their height as required with support silicagel column 5A.Starting switch 7 has two, will press simultaneously could start shaping tool, prevent maloperation.Plastic parts 4 is put on the support silicagel column 5A that master mold 5 is installed, presses two starting switches 7 simultaneously, moving platen 3 can be promoted to move downward by the piston rod of cylinder 1, the location silica gel block 3B that moving platen 3 is installed pushes down plastic parts 4, fix the position of plastic parts 4, shaping silicagel column 3A, to lower compression plastic parts 4, corrects the distortion of plastic parts 4, keep oppression state 10-15S, lower than 10S, shaping effect is undesirable, higher than 15S, plastic parts cools, meaningless.Last operation moving platen upwards reclaims, and takes out plastic parts 4, completes shaping.
The present invention is the internal stress utilizing high temperature to eliminate plastic parts, be equivalent to " annealing ", and high temperature turn increases the plasticity of plastic parts, is beneficial to and corrects distortion position.
The above is a preferred embodiment of the present invention, and when not departing from the present invention's design, any apparent distortion carried out and replacement, all belong within scope.
