Abstract

PURPOSE:To make position control of a mold, whose weight is heavy, controllable accurately, with little labor and in a short period of time, by providing a plurality of pedestals on the external circumference of a fitting rest on which a bottom force is mounted, and driving an adjusting screw into the same so that the tip of the screw abuts against the bottom force. CONSTITUTION:A plurality of pedestals 22 are provided on a position close by the circumference of a fitting rest 17 of a resin molding press, that is, the external circumference of a bottom force 16. The number of the pedestals 22 is determined according to the size of the bottom force 16 and a form of the bottom force 16. An adjusting screw 23 is driven into the pedestal 22 so that the adjusting screw 23 moves horizontally and abuts against the external circumference of the bottom force 16. The tip of the adjusting screw 3 pushes the external circumference of the bottom force 16 by turning the adjusting screw 23 and moves the bottom force 16 finely in the direction of X-Y within a horizontal surface. The bottom force 16 and a top force 8 which has been put upon the bottom force 16 move finely in the direction of the X-Y within the horizontal surface and position control of a mold whose weight is heavy can be performed with little labor and in a short period of time.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] This invention relates to a positioning device for a resin mold provided in a resin mold brace used in manufacturing resin-punched electronic components.

[Prior Art] FIG. 3 is a schematic diagram of a resin mold press used in manufacturing resin 14-stop type electronic components.

In the figure, reference numeral 1 denotes a main pillar for constructing the frame of this resin mold press. It is fixed with screws 5.

An upper mold 8 is suspended from the upper stand 4 via suspension members 6.7. That is, the suspension member 6 is fixed to the upper stand 4 with screws 9, the horizontal suspension member 7 is fixed to this suspension member 6 with screws 1o, and the upper A mold 8 is fixed with screws 11.

A pot portion 12 for storing the resin phase is provided in the upper mold 8, and a plunger 15 provided at the tip of a piston shaft 14 of a cylinder 13 attached to the upper table 4 moves forward and backward into the pot portion 12. It will be inserted like this.

A lower mold 16 is arranged opposite to the upper mold 8,
This lower mold 16 is fixed to a mounting base 17 with screws 18, and this mounting base 17 is a base 1 that can be raised and lowered in the vertical direction.
9, this base 19 is inserted through the main pillar 1, and is provided so as to be vertically movable by a lifting mechanism 20 provided on the base 2.

Note that a cavity 21 is provided in the lower mold 16 described above.

In the resin mold press configured as described above, the lower mold is first raised by the operation of the elevating mechanism 20 and brought into close contact with the upper mold.

Next, due to the operation of the cylinder 13, the piston shaft 14
The plunger 15 is lowered through the , and inserted into the pot part 12 of the upper mold 8, and the resin phase that has been charged in advance is poured into the pot part 12 of the upper mold 8.
The molten resin extruded from the pot part 12 is extruded into the cavity 21 of the lower mold 16 via a run 9' and a cage (not shown). , the electronic component supported within the cavity 21 is coated with resin DI tlt.

Thereafter, the lower mold 16 is lowered by the lowering mechanism 20, and the resin-sealed electronic component is taken out from the cavity 21.

In the resin mold breather configured as described above, the relative position of the plunger 15 and the pot portion 12 into which the plunger 15 is inserted must be accurately aligned during initial setting. In that way, it was not aligned.

That is, first, attach the screws 11 and 18 to the hanging part H47 and the mounting base 16, respectively.
Without firmly fixing the plunger 15, hit the outer periphery of these parts with a hammer and move them little by little in a horizontal plane.
The adjustment work is carried out by aligning so that the gap with the pot part 12 is a predetermined gap, and when the positions are aligned, the screws 11.18 are tightly tightened.

[Problems to be Solved by the Invention] The position adjustment work in a conventional resin molded press is performed as described above, and in that case, the upper and lower molds 8 generally used for this type of resin molded press are .16 is heavy, and may weigh more than 1 ton. In such cases, the outer periphery of the upper and lower molds 8.16 is struck with a hammer to remove the gap between the plunger 15 and the pot part 12. For example, there is a problem in that adjusting the gap to have a uniform gap of 0.05 to 0.08 mm requires a great deal of labor and time.

[Purpose of the Invention] This invention was made to solve the above-mentioned problems, and it is possible to accurately connect the plunger 15 and the pot part 12.
It is an object of the present invention to provide a positioning device for a resin mold that can adjust the gap between the resin mold and the mold with less labor and in a short time.

[Means for solving the problems] The positioning device for resin molding die according to the present invention has the following features:
A plurality of pedestals are provided on the outer periphery of the tray on which the lower mold is placed, and adjustment screws are screwed into the pedestals so that the tips of the screws touch the outer periphery of the lower mold.

[Operation] In the positioning device for resin molds of the present invention, by turning the adjusting screw provided on the pedestal, the tip of the adjusting screw pushes the outer periphery of the lower mold and aligns the X-
Move the lower mold slightly in the Y direction.

[Example] Examples of the present invention will be described below with reference to FIGS. 1 and 2.
This will be explained with reference to the figures.

Note that the same or corresponding parts as in FIG. 3 showing the conventional example are given the same reference numerals, and detailed explanation thereof will be omitted.

Therefore, a plurality of pedestals 2 are provided around the mounting base 17 of the resin mold press, that is, at a position close to the outer periphery of the lower mold 16.
2 will be provided. The number of pedestals 22 is determined by the size and shape of the lower mold 16, or if the lower mold 16 is a rectangular parallelepiped as in this embodiment, at least the opposing surface of the rectangular parallelepiped. One set is provided on each side, and the structure allows adjustment from both sides of the opposing surfaces.

An adjustment screw 23 is screwed into the pedestal 22 described in -1- so as to move forward and backward in the horizontal direction so as to contact the outer periphery of the lower mold 16.

In the above configuration, the adjustment screw 23 can be turned with a tool such as a spanner by the thrust of the adjustment screw 23, and the lower mold 16, which is heavy, and the upper mold superimposed on the lower mold 16-L can be The mold 8 moves slightly in the X-Y direction. Therefore, the adjustment screws 23 in each direction are turned alternately, the plunger 15 is lowered each time, and the adjustment is repeated until the gap with the pot part 18 becomes uniform. When the gap becomes uniform, the screw 11. 18 is sufficiently tightened to completely fix the upper and lower molds 8 and 16, and the initial setting is completed.

[Effects of the Invention] As explained above, in the present invention, a plurality of pedestals are provided on the outer periphery of a mounting base on which the lower mold is placed, and an adjustment screw is provided on the pedestal at the tip E or the outer periphery of the lower mold. By turning the adjustment screw, the lower mold and the upper mold superimposed on the lower mold can be easily moved slightly in the X-Y direction within the horizontal plane, and can be easily moved using a hammer or the like as in the conventional method. without using
The position adjustment of heavy molds can be done in a short time and without much labor, resulting in excellent effects.
