Description
[0001] The present invention relates to a cable-integrated grommet forming apparatus, and more particularly, to a cable grommet forming apparatus capable of directly mounting an aligned and integrated cable directly on a mold, To a molding apparatus.
Generally, an injection molding apparatus is a method for producing a molded article corresponding to a hollow portion of a mold by pressurizing and injecting into a cavity of a mold when the thermoplastic resin is heated to a fluidized state and then cooled in the mold.
The grommet is used to protect the cable inserted into the perforated hole from being broken by the cut surface of the hole. These grommets are manufactured in a state in which the cables are integrated when forming the grommet when watertight coupling is required, thereby achieving perfect watertightness.
As described above, the cable-integrated grommet forming apparatus is filed by the present applicant and is registered in No. 10-1239183.
A top mold is provided on a bottom surface of the upper mold so that the grommet can be formed on the supplied cable, a lower mold is provided on an upper portion of the lower mold corresponding to the upper mold, an upper mold is lowered by a separate raising / lowering device, A molding apparatus for forming a grommet in which a molten material is supplied to a cavity in which a lower mold is formed to mold a grommet, and an upper mold is lifted and opened to take out a grommet formed on a cable, An upper plate having an upper mold capable of forming a grommet on a bottom surface thereof; A mounting plate mounted on the upper plate; And a heater device mounted on the mounting plate for heating the molten material for grommet forming supplied from the outside to supply the molten material to the cavity so as not to solidify; Wherein the lower mold is located on a lower portion corresponding to the upper plate and the lower mold is provided on an upper surface capable of forming a grommet in cooperation with the upper mold; The upper mold is lifted up and down when the lower mold is opened, and the grommet formed in the lower mold is lifted and taken out to be taken out. When the lower mold is lowered when the grommet is formed Core plate; A core plate raising / lowering unit located at a lower portion of the core plate, for raising / lowering the core plate; And a base for supporting the upper mold and the lower mold; .
A conventional grommet-molded wiring assembly molding apparatus having such a structure can selectively replace the pedestal depending on the number of cables to be formed with the grommet, the position of the cable can be easily designated according to the length, And the molded part of the runner is taken out together with the grommet in the lower mold, so that the molding process can be simplified.
This molding apparatus produces a cable in which the grommet is integrated through the following process. First, a cable mounting step of arranging and fixing a cable directly to a core plate and a holding groove by an operator, a lower mold transferring step of moving a lower mold equipped with the cable to a lower mold with a nozzle, a lower mold lowering step, A cooling step of solidifying the material in the cavity, and a releasing step of releasing the cable in which the grommet is integrated, from the cavity.
Such a molding apparatus is a turntable type in which a mold releasing step and a cable mounting step are performed on one side and a material supplying step and a cooling step are repeated on the opposite side at the same time. Here, the cable mounting step and the mold releasing step are manually performed by the operator, and the lower mold transferring step, the material supplying step and the cooling step are automatically performed by the controller. While the material supplying step and the cooling step are completed in a short time, The cable mounting step of fixing and arranging the cables is time consuming and the product mounting is still completed on the opposite side.
If you look at the cause of the time required to install the cable, it is necessary to select the cable of the predetermined color among the prepared cables, fix it one by one according to the predetermined position, and fix the cable to the predetermined length, .
In addition, if the cable is misaligned or the cable is not fixed to a predetermined length by the operator in the cable fixing step, it leads to a product defect. Such a product defect is due to the grommet being integrated, and therefore it can not be recycled, There is a problem that the working time of the process (cable terminal work, grommet forming work) is wasted and waste of material (cable, terminal, grommet) is wasted.
Accordingly, it is an object of the present invention to provide a cable fixing clip which can be quickly mounted on a molding apparatus by forming a bundle of a plurality of cables easily arranged and fixed so as to solve the conventional problems, .
It is still another object of the present invention to provide a cable integrated type connector capable of maximizing productivity by greatly shortening a cable fixing operation time in a molding apparatus by allowing a cable in a state in which an arrangement is already completed by a cable fixing clip to be installed in a grommet forming apparatus And to provide a mat molding apparatus.
According to an aspect of the present invention, there is provided a clip for fixing a cable,
A fixture having a plurality of grooves opened at an upper portion thereof at regular intervals so that a cable can be inserted therein;
A cover coupled to an upper portion of the fixing table to seal the groove; .
In addition, the fixing table has hooks formed at both ends thereof, and the cover forms hooks hooked on the hooks.
In addition, the fixing table has two or more pairs of recesses forming a pair, an assembly groove is formed between each pair, and the cover has an assembling protrusion which is engaged with the assembly groove.
In addition, the cover may have a grip portion protruding longer than the fixing base by extending one end thereof so that the cover can be easily opened.
Further, the cover is characterized in that a pushing piece for pressing a cable inserted into the groove is protruded.
In addition, the cover has a support piece which is in close contact with an inner side surface formed with a locking protrusion of the fixing table, and a thin folded portion is formed in a section between the support piece and the groove of the fixing table so that the other end is opened and opened with respect to the folded portion. .
Further, in the cable-integrated grommet forming apparatus,
The injection molding apparatus according to any one of
The lower die has a plurality of cable insertion grooves for guiding a cable to be mounted to the cavity, and clip mounting grooves opened upwardly are formed to cross the cable insertion grooves.
In addition, the clip mounting groove is formed with a space portion in which the clip to be mounted is not closely contacted.
In addition, the lower die is capable of detachably attaching a jig to one end thereof, and the cable insertion groove and clip attachment groove are formed in the jig.
The cable fixing clip according to the present invention having such a structure is simple in structure and easy to be molded, and a cable can be simply and easily inserted into a groove.
Further, since the clip cover is provided with the pushing piece, the inserted cable can be effectively pressed and fixed even if the depth of the recess is deep, and the recess is formed deeply so that the cable is not easily detached from the groove when the cable is inserted.
Further, since the clip has a plurality of assembly grooves and assembling protrusions, even if a large number of cables are inserted, the cover can be partly joined and the cable can be inserted.
Further, the other end of the clip can be opened and closed with one end of the cover fixed, thereby preventing the cover from being lost and opening the cover quickly and easily by the laterally protruding gripper.
Since the cable-integrated grommet forming apparatus according to the present invention has the clip mounting groove formed at one end of the lower mold, the cable, which is already arranged and fixed to the clip, can be mounted on the lower mold with the clip member, It is effective.
In addition, since the defective rate is close to zero because only the good products are selected through the inspection process and the grommet is formed, the cable misaligned in the inspection process can be recycled, and there is no waste of material.
In addition, by using the jig having the cable insertion groove and the clip mounting groove formed therein, when the number of cables and the size of the clip mounting groove are changed, only the jig can be manufactured and replaced, .
