JPS58188637A - Apparatus for trimming burr - Google Patents

Abstract

PURPOSE:To obtain the titled apparatus for preventing the production of inferior goods, and preventing burr from remaining on an air vent part, by providing a resin made brush removing the burr on the air vent part rotating and the compression air blowing brush nozzle positioned at the upper part thereof. CONSTITUTION:An apparatus 15 for removing burr is transferred to the direction G by advancing it to the direction E after taking out molded parts after molding. The resin made brush 16 is rotated, compressed air being blown to the die faces 3a and 6a of molds 3 and 6 from nozzle 18 at the same time, and the remaining burr on the air vent part 2a is removed by blowing off the burr attached thereto. To change the molds 3 and 6, the opparatus 15 for removing burr is transferred to the directions H and F.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a deburr removal device that removes deburr adhering to the mating surfaces of molds.

Conventionally, the process of removing pars from spears involves blowing compressed air into the air vent every cycle of the molding process to blow away the pars and remove the pars. In many cases, it was necessary to manually remove the paris. Also, if you do not do this, depending on the situation, there may be some debris left in the air vent, resulting in an 81-year failure.
On the other hand, the gas generated from the fat was prevented from escaping from the cavity of the mold, and for example, unfilled and defective products were sometimes produced.

This invention was made in view of the above-mentioned circumstances, and its primary purpose is to prevent debris from remaining in the air vent and to release gas generated from the resin during molding to prevent defective products. We provide a deburring device that prevents this from occurring.

The present invention will be explained below based on FIGS. 1 to 3, which are one embodiment. 1 is a thermosetting resin injection molding machine;
A fixed plate 4 is equipped with a fixed mold 3 having a cavity 2, a movable plate 7 is mounted with a movable mold 6 having a core 5 and moves forward and backward, and the molten resin is inserted into the cavity 2 using, for example, a screw or a plunger. It consists of a nozzle 8 that injects water inside. 2a is, for example, floor 0. Of~0.
This is an air vent part made of 07■ clear, which is formed by passing through the cavity 2 and the outside 3bIc on the mating surface 3 of gold m3, and vents the gas generated from the resin during molding from the cavity. Note that the air vent portion 2a may be formed by a protrusion, and may also be formed by a movable metal plate. ! 1i6 may be formed. Reference numeral 9 denotes a take-out device, which takes out the molded part 11 integrated with the lunch 10 after molding from the movable mold 6, grips the spool 4 with the handling unit 13, takes out the molded part 1, and transfers it to the belt conveyor 14. collected in one place by. lla is Paris, and air vent part 2a
It is formed in 1b is a deburring device;
For example, a resin brush holder made of nylon or the like, a motor 17 that rotates the resin brush 56, and a mold located above the resin brush 1 are arranged at t3m and 6m.
The deburring device jJ&: is moved forward and backward by the cylinder A, and the deburring device 15 is moved upward and downward by the cylinder B. 59 is an air hose. Paddy is on the parting line.

After molding, the molded part 11 is taken out by the take-out device 9, and then the deburring device 1! is taken out by the cylinder A. moves forward in the E direction. Then, cylinder B moves it in the G direction. At this time, while rotating the resin brush 16, compressed air is sprayed from the nozzle tS onto the four mating surfaces 3a and 6a of the mold 3.6, so that the mold 3.
6 combined maa.

This removes the particles that have adhered to the air vent portion 1 and removes the particles that remain in the air vent portion 2a. In this way,
As shown by the diagonal line X in Fig. 3, the action of removing the parts from the air vent part 2m is performed by moving the resin brush 16 and removing the dust from the air vent part 2m.
I got better by just doing it once every 50 cycles. In addition, when replacing the mold 3.6, it is necessary to
+Cylinder B moves it in the H direction, and cylinder A moves it in the F direction, so that the replacement work is not hindered.

As explained above, this invention is mounted on a thermosetting resin injection molding machine 1, and moves while rotating the air vent part 2a formed on the mating surfaces 3m and 5m of gold u3 and 6. (It consists of a resin brush 16 and a nozzle 1s located above the resin brush 16 that blows compressed air onto the mating surfaces 3m and 5a of the mold 3.6. This prevents particles from remaining in the air vent part 2a even if the adhesive is strong, and releases the gas generated from the resin during molding to prevent defective products. Side 3
Paris attached to a15a can be removed at the same time, mold 3.6
It is possible to obtain a deburring device that does not obstruct replacement work.
