At this time, the opening 40a on the lower surface of the subpot 40 is rotated to the retracted position by the control mechanism provided in the container of the transport block 3 with the tablet stopper 42 facing the stopper piece 43 there. Since the opening 40a is open, the tablet T to be pushed up is inserted into the subpot 40 as shown in FIG. Then, when the charging of the tablet T into the subpot 40 is completed, the tablet stopper 42 is rotated to the operating position by the operation of the control mechanism, and the lower edge of the inserted tablet T is as shown in FIG. At the same time, the push-up block 6 is lowered and the state shown in FIG. 8 is obtained.

  Next, the transport block 3 moves from this state toward the upper position of the upper surface of the lower mold D of the mold apparatus A, and each subpot 40 of the subpot block 4 supported on the lower surface moves to the upper surface of the lower mold D. The state shown in FIG. 9 is opposed to each of the mold pots P formed in the shape.

  Next, the lower mold D of the mold apparatus A is raised, and the respective mold pots P of the lower mold D are positioned below the subpots 40 of the subpot block 4 to obtain the state shown in FIG.

  Next, in this state, the tablet stopper 42 closing the opening 40a on the lower surface of each subpot 40 is released as shown in FIG. 11, and the tablet T loaded in each subpot 40 is released. Due to its own weight, it falls into the mold pot P of the lower mold D and is supported by the plunger 70 installed in the mold pot P, resulting in the state of FIG.

  Next, the moving platen 13 is lowered and the lower mold D is pulled away from the subpot block 4 (FIG. 13). In this state, the transport block 3 is moved backward to return the subpot block 4 to a position below the frame block 2. FIG. 14 shows the state.

  Next, the movable platen 13 is raised by the operation of the press mechanism 14, and the lower mold D is joined to the upper mold D 'to obtain the state shown in FIG. In this state, the heating device incorporated in the lower mold D and the upper mold D ′ and the operation of the plunger 70 cause the tablet T of the thermosetting resin to be in a molten state on the mold at a high pressure. It is injected into the formed cavity 71, thermally cured, transported to the parting surface together with the resin tablet T by the transport block 3, molded and molded with a product part 72 such as a lead frame placed and dropped. Mold into a product. Next, the lower mold is lowered and the molded product is taken out.

  In this way, the supply of the resin tablet T to the mold pot P provided in the lower mold D of the mold apparatus A is provided in the subpot block 4 that advances and retreats in the front-rear direction with respect to the mold surface of the lower mold D. The subpot 40 is formed in a subpot block 4 formed into a horizontally long prismatic shape by a light metal material such as an aluminum alloy, and the inner diameter of the subpot 40 is larger than the outer diameter of the resin tablet T formed into a cylindrical shape. It is formed in a regular cylindrical hole having a size of a large diameter, whereby when the tablet T in the supply hole 50 of the supply block 5 is received in the subpot 40, the resin tablet T in the subpot 40 is also received. Is dropped into the mold pot P of the lower mold D, the peripheral surface of the resin tablet T is slidably brought into contact with the inner wall surface of the subpot 40 to be guided.

  The subpot 40 formed in the subpot block 4 is filled with a cylindrical tablet T from the supply hole 50 of the supply block 5 every time a molding process is performed. Since it falls to P, when the molding work is performed by the automatic molding apparatus, wear occurs on the inner wall surface that is in sliding contact with the peripheral surface of the cylindrical tablet T that comes in and out, and the metal of the metal material that is formed Generate powder.

  By the way, the wear generated on the inner wall surface of the subpot 40 is not uniformly performed in the circumferential direction of the inner wall surface, but is generated unevenly. From this, the shape of the opening 40a on the lower surface, which is the insertion port of the tablet T with respect to the mold pot P of the lower mold D, is distorted, the insertion position of the tablet T into the mold pot P is distorted, and the insertion cannot be performed. It causes a problem that causes a bug.

  In addition, the metal powder generated by sliding contact when the resin tablet T comes in and out enters the mold pot P together with the tablet T and is mixed into the molten thermosetting resin, so that the molded electronic component is defective or marked. It causes problems that cause quality degradation.

  Further, when the resin tablet T is sticky in the process of moving the sub pot block 4 above the lower mold D and dropping the resin tablet T in the sub pot 40 onto the mold pot P by releasing the tablet stopper 42. The peripheral surface of the tablet T adheres to and adheres to the inner wall surface of the subpot 40, causing a problem that it does not drop and causes an insertion error.

  The problem to be solved in the present invention is a problem that occurs in the automatic molding apparatus in relation to the subpot 40 of the subpot block 4 that transports the resin tablet T to the mold pot P provided in the lower mold D. That is, the inner wall surface of the subpot 40 is deformed due to wear caused by sliding contact with the tablet T that comes in and out every time the tablet T is supplied, and the normal tablet T is dropped and put into the mold pot P. , Problems that cause input mistakes, and problems that cause defective products with reduced quality in molded parts of molded electronic components by mixing metal powder generated by sliding contact with the tablet T into the resin material, and When the tablet T is sticky, the tablet T adheres to and adheres to the inner wall surface of the subpot 40, causing a mistake in the insertion into the mold pot P. In order to eliminate this problem, even if the subpot 40 is worn by sliding contact with the tablet T entering / exiting, the tablet T can be removed without causing distortion on the sliding contact surface that guides the tablet T entering / exiting. Metal that correctly falls into the mold pot P, and even when the tablet T is solid, it can be properly dropped into the mold pot P without causing adhesion and sticking, and it can cause defects in the molded product.

  Next, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

  16, 17 and 18 show a subpot block for carrying out the means of the present invention. FIG. 16 is a perspective view as seen from the upper surface side of the subpot block 4 and FIG. 17 is a perspective view as seen from the lower surface side. 18 and 18 are rear views of enlarged vertical sections. In the figure, 4 is the entire subpot block 4, 40 is a subpot formed in the subpot block 4, 8 is an inner wall portion of the subpot 40, and a part of the peripheral surface is exposed and protrudes into the subpot 40. A ceramic rod-like body embedded in the state, T indicates a tablet charged in the subpot 40.

  The subpot block 4 is formed in a prismatic block that is long in the front-rear direction (left-right direction in the figure). The sub pot block 4 is for feeding a resin material tablet T for molding a product part to a mold pot P formed in a lower mold D. Although it may be formed using an appropriate material, in this example, it is formed using aluminum metal.

  The subpot 40 to be formed in the subpot block 4 receives a tablet T formed by pressing and solidifying a powdered resin material into a columnar shape from the opening 40a on the lower surface side, and moves the subpot block 4 by moving the subpot block 4. It is transported to a position above the mold pot P of the mold D, where it functions to drop the tablet T by its own weight and put it into the mold pot P. In order to allow the columnar tablet T to be inserted into the mold pot P in an upright posture with the axial direction being the vertical direction, the inner diameter of the tablet T is formed in a vertical cylindrical shape larger than the outer diameter of the tablet T. It is set up.

  The subpots 40 are formed so as to correspond to the number of mold pots P formed in the lower mold D and to be arranged in parallel with the subpot block 4. Further, the subpot 40 is provided with a mold pot P in order to properly pressurize the tablet T by the plunger 70 during the molding process performed by closing the lower mold D and the upper mold D ′. Since it is desired that the columnar tablet T is put in an upright posture in which the axis is in the vertical direction, the entering and leaving the columnar tablet T is regulated and guided to the upright posture. Function is required.

  In the past, the columnar tablet T is regulated and guided in an upright posture. In the past, the subpot 40 is formed in a cylindrical shape, and the outer peripheral surface of the tablet T that enters and exits and the inner peripheral wall of the subpot 40 are connected to each other. It is done by sliding contact.

  However, in the means of the present invention, the guide for regulating the posture of the tablet T to be brought in and out is provided by the ceramic rod-like body 8 embedded in the inner wall portion of the subpot 40, and the sliding between the inner peripheral wall of the subpot 40 and the outer peripheral surface of the tablet T is performed. I try not to touch. Therefore, the subpot 40 does not need to be formed into a cylindrical shape, and may be formed into a cylindrical shape having an appropriate shape such as a polygonal cylindrical shape, as long as the tablet T comes and goes in an upright posture. The reason why it is formed into a cylindrical shape in this embodiment is that the forming process is easy.

  As shown in FIG. 19, the ceramic rod-shaped body 8 is an inner wall portion of the subpot 40 formed in the cylindrical subpot block 4, and a part of the peripheral surface is formed at three portions substantially equally arranged in the circumferential direction. It is embedded as a state of being exposed and protruding from the inner cavity of the subpot 4.

  The three parts equally distributed in the circumferential direction are arranged in parallel in the circumferential direction so that the projecting edges (i) of the circumferential surfaces of the respective rod-like bodies 8 into the lumens of the subpots 40 are provided. 19, which is a plan view of the subpot 40, the outer diameter of the tablet T, which is located on the virtual image line of the virtual circle and is inserted in the subpot 40, is indicated by the virtual line (B) in FIG. If it corresponds to a circle, the outer peripheral surface of the tablet T is slidably contacted only with these projecting edges (A), the tablet T is held in an upright posture, and is regulated and guided in an upright posture. Because it becomes like this.

  Accordingly, the protrusion height of the part of the peripheral surface of the rod upper body 8 that protrudes into the subpot 40 and the protrusion height from the inner wall surface of the subpot 40 is an imaginary line connecting the protrusion edges (A) of the protrusions 8a. The locus of the circle is set so as to correspond to the outer diameter of the resin tablet T to be used.

  In addition, from this, the number of the ceramic rod-like bodies 8 arranged in parallel in the annular shape and embedded in the inner wall portion of the subpot 40 may be set as desired, such as four, five, six, and eight.

  The upper rod body 8 embedded in the inner wall portion of the subpot 40 in a state in which a part of the peripheral surface protrudes from the inner wall surface of the subpot 40 slidably contacts the peripheral surface of the tablet T that enters and exits the subpot 4. By limiting the portion to the protruding end edge of the rod-shaped body 8, the sliding contact by random surface contact with the inner wall surface of the sub-pot 40 is performed along the protruding edge of the rod-shaped body 8. By limiting the wear due to sliding contact to the portion of the protruding edge that makes line contact, it is made to function so as to suppress disturbance in the regulation of the posture of the tablet T that comes in and out caused by random wear due to surface contact.

  And the structure which has formed this rod-shaped body 8 with the ceramic is for suppressing the abrasion which arises in a sliding contact site | part using the high abrasion-proof property of a ceramic.

  The ceramic for forming the rod-shaped body 8 may be a normal ceramic obtained by firing an inorganic substance, but may be a ceramic obtained by firing alumina oxide. In this example, a ceramic obtained by firing partially stabilized zirconia having remarkable wear resistance is used.

  The embedding of the ceramic rod-shaped body 8 in the inner wall portion of the subpot 40 is performed by forming the ceramic rod-shaped body 8 formed separately when the subpot block 4 is formed into a form in which the subpot 40 is mounted. It is embedded vertically in the inner wall portion of the subpot 40, or the inner diameter of the molded subpot block 4 is set to an inner diameter into which the separately formed ceramic rod-shaped body 8 is inserted into the inner wall portion of the subpot 40 formed thereon. As shown in FIG. 21, a round hole-shaped fitting hole 9 in the direction is opened as a shape in which a part of the hole wall is cleaved 9a with respect to the lumen of the subpot 40, The ceramic rod-shaped body 8 may be inserted and firmly fitted so that escape is prevented, so that the embedded state may be obtained. In this embodiment, the fitting hole 9 is formed into a round hole. And ceramic By molding the rod-like body 8 into a round bar, and allowed buried by fitting them.

  As described above, the subpot 40 in which the ceramic rod-like bodies 8 are embedded in the inner wall portion and arranged in parallel in an annular manner at intervals in the circumferential direction is in contact with the tablet T that comes in and out. Only the protruding end edge (a) of the protruding portion 8a of a part of the peripheral surface of the rod-shaped body 8 protruding from the inner wall surface is guided by the line contact by the protruding end edge (a). Therefore, even if wear occurs due to the sliding contact, the tablet T is held in an upright posture and guided accurately. And since this site | part which contacts is an abrasion-resistant ceramic, generation | occurrence | production of the metal powder which arises by sliding contact can also be suppressed now. Further, when the fitting hole 9 is formed into a round hole and the ceramic rod-shaped body 8 is molded into a round bar and fitted, the rod-shaped body 8 is pulled out when wear occurs on the protruding edge (A). By rotating and re-fitting, the wear can be repaired.

  The protruding end edge (a) of the protruding portion 8a of the ceramic rod-shaped body 8 may be chamfered into a narrow plane as shown in FIG. On the contrary, as shown in the example shown in FIG. 23, the left and right peripheral surfaces of the projecting portion 8a are each formed into a flat shape, formed into a wedge shape in plan view, and the projecting end edge (A) is shaped like a blade edge. May form.

  In the figure, the notch provided in the opening edge portion 40a of the opening 40a on the lower surface side of the subpot 40 indicated by reference numeral 45 is when the subpot 40 receives the tablet T pushed up by the push-up bar 60 from below. The stopper piece 43 of the tablet stopper 42 that supports the lower surface of the tablet T and prevents the tablet T from falling is a cutout portion into which the tablet stopper 42 is inserted.

  24, 25, and 26 show another embodiment. In this example, the ceramic pot-shaped body 8 provided on the inner wall of the subpot 40 with a part of the peripheral surface protruding into the inner cavity of the subpot 40, the subpot 40 at the lower end facing the opening 40 a on the lower surface side of the subpot 40. This is an example in which a guide surface 80 for guiding the columnar tablet T pushed up by the push-up bar 60 toward the inside of the subpot 40 is provided at a portion protruding inward.

  24 and 25, the guide surface 80 is processed so that a portion protruding from the inner wall surface of the subpot 40 at the lower end portion of the rod-like body 8 is cut obliquely, and the center of the inner space of the subpot 40 In addition to the case where the inclined surface that rises obliquely toward the portion is formed and the guide surface 80 is configured with the inclined surface, the lower end portion of the rod-shaped body 8 projects from the inner wall surface of the subpot 40 as shown in FIG. The guide surface 80 may be appropriately configured by forming it into a tapered half-cut conical shape and forming the peripheral wall surface thereof into the guide surface 80. The subpot 40 of this embodiment is directed toward the center by the guide surface 80 formed at the lower end portion of the rod-shaped body 8 even if the tablet T received from the opening 40a on the lower surface side is offset with respect to the center of the subpot 40. Since it is guided, the tablet T can be received smoothly.

  27 and 28 show still another embodiment. In this example, in the subpot 40 of the above-described second embodiment, the guide surface 80 formed on the lower end portion of the rod-shaped body 8 is formed on the portion protruding from the inner wall surface of the subpot 40 of the rod-shaped body 8. The lower end portion of the rod-like body 8 is processed to be chamfered obliquely to the portion embedded in the subpot block 4 to form the guide surface 80, and the lower end side that is the starting end of the guide surface 80 is This is an example in which the lower end side of the opening 40a on the lower end side of 40 is expanded outward. In this example, when the lower end portion of the rod-like body 8 is chamfered obliquely to the embedded portion, the chamfering processing is performed together to the mouth edge portion of the opening 40a on the lower surface side of the subpot 40. The opening 40a is in an expanded state by forming an inclined chamfer 46 that follows the guide surface 80 formed at the lower end of the rod-like body 8 at the edge.

  For this reason, in this example, even if the tablet T pushed up by the push-up bar 60 is inclined from the lower side of the subpot 40, the upper end shoulder portion is detached from the opening 40a of the subpot 40. Without being seized, it will be guided into the subpot 40 and the receiving operation of the tablet T will be smooth.
