Abstract

To provide a template positioning apparatus which requiries no adjusting labor and time and genuinely performing the positioning of a template. A pin 12 is attached to a movable side template 5 and a bush 21 is attached to a fixed side template 4. The outer diameter of the tip part 32 of the pin 12 is fitted to the inner diameter of the first positioning hole 18 of the bush 21. A ball retainer 23 with a diameter d2 provided to the root of the pin 12 through a leaf spring 34 is pressed into the second positioning hole 17 of the bush 21 with an inner diameter D2 in a preloaded state. At the time of mold closing, the pin member is guided by the first positioning hole 18 and the templates are roughly positioned and, immediately before mold closing, the ball retainer is inserted in the second positioning hole 17. The clearance between the ball retainer and the pin/bush is zero and the templates are positioned precisely.

Description

498019 A7 V. Description of the invention ()) [Technical field of the invention] The present invention relates to a device that uses / 仞 仞 要 $ $ $ $ the side plate blood can move like π 4 position device, is set in the forming mold a Extremely, the material of the moving side branch plate is filled in the form of @ 定 侧 ~ ', and the Chengli mold system will be (Ca >) to form the product. 1, a mold cavity between the movable side of the template [known technology] Figure 10 is a conventional positioning device with a conventional positioning device of the stiffener 1 This mold is equipped with.丨 view. The fixed-side mounting plate 2 on the fixed side of the waste machine of the Hetubu forming machine, and the movable-side mounting plate 3 on the side of the oven. Li W also has a fixed-side mounting plate 2 that is Anluo's right-touch sturdy > female-type fixed-side template 4. Fixing :: Cloth plate: ’The mouthpiece bush) i is installed as a path for injection from the cylinder nozzle of the molding machine when it is in the forming core. The resin injected from the self-washing mouthpiece 10, although it is shown in the figure, is entered into the flow channel formed on the fixed-side template 4 side, and is washed into D (gate) to enter the mold cavity. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. A mounting plate 3 'is installed on the movable side, and a mounting plate 6 and a spacer 7 are installed on the movable side. This forming mold! It can be divided between the fixed-side template 4 and the movable-side template 5 to cooperate with the loss of the forming machine. The movable-side template 5 moves to the fixed-side template 4 in a direction perpendicular to the plate surface, thereby fixing the side plate. 4 and the opening and closing of the movable side template 5. When the fixed-side mold plate 4 and the movable-side mold platen are closed, a cavity A corresponding to the molded product is formed. Positioning two templates Between the fixed-side template 4 and the movable-side template 5, a positioning device is provided for intersecting the templates at a regular position. This positioning device conforms to the Chinese paper standard (CNS) A4 (210x 297 male cage) 498019 A7 B7 as per the paper size 312608. V. Description of the invention (2)! The picture shows the bushing on the fixed side template. η, and a pin 12 provided on the movable-side template. When the mold is closed, by inserting the pin 12 into the bushing 11, the two templates 4 and 5 will be positioned at regular positions. Fig. U is a sectional view of a mold including another example of a conventional positioning device. This mold structure is roughly the same as that in the first figure. The positioning device of this mold is shown in an enlarged view in FIG. 13 and has a female member 14 mounted on a fixed side template 4 by a sling plate 13 and a sling plate 15 on the movable side. Male members 1 of template 5. A concave portion i4a having a tapered guide surface is formed in the female member U, and a convex portion i6a with a tapered guide surface is formed in the male member 16. When the mold is closed, by inserting the tapered convex portion 16a of the male member i6 into the tapered concave portion 14a of the female member, the two templates 4, 5 are positioned at regular positions. [Problems to be Solved by the Invention] In the positioning device shown in Figs. 10 and 11, since the pin 12 and the bushing u are in surface contact, there is a range of 0 to 100 between the pin 12 and the bushing. .〇4 With the clearance (diagram D ♦, due to the weight of the mold and the injection force during molding, etc., the two templates only use the gap component to produce a relative positional shift in either direction. Especially For the molded products, the main model is a model forming machine with the opening direction of the main mold in the horizontal direction. Therefore, due to the large influence of the mold and its own weight, it is easy to cause the problem of the side deviation of the molded product. God seconds is shown in Figures 11 and 13 In the positioning device shown, to adjust the female member w and the male member 16 to the regular position correctly, the installation work has the paper size applicable to the Chinese National Standard (CNS) A4 specification (210 x 297 mm) L 312608 498019 5 The invention is laborious and time consuming. The positioning device of the cone surface used by the staff of the Intellectual Property Bureau of the Ministry of Economic Affairs to print the magazine is finally required to see the two members 14 and 16 when the mold is closed. Cone The abutment situation is adjusted by grinding the gasket u or 5 used for installation. This operation is not only to confirm the abutment situation of the female member and the conical surface of the male member 16 and to measure the size, but also to measure the fixed side. The size of the template 4 and the movable side mold is reversed to the size of 5 or the assembly side must be performed at the same time, so it takes a lot of man-hours and time. Also, confirm that the abutment of the tapered surface is intuitive, and you need to be proficient in adjustment. U Again According to the above-mentioned positioning device of FIG. 13 using a tapered surface, when the angle of the tapered portion (the convex portion! 6a, the concave portion 14a) is larger than 00 to ...), most of them are adjusted so that the miscellaneous surfaces enter more or less, but This is the cause of easy biting or breakage. In addition, when the taper angle is small, it is adjusted to make it float more or less due to the consideration of bite, so there is less contact between the taper surfaces and a gap is generated, and there is a problem that a sufficient positioning function cannot be obtained. It is an object of the present invention to provide a positioning device that does not require labor and time for adjustment and can reliably position a template. [Means for Solving the Problem] Shin-Month Patent | The positioning pin (pin members 41 to 45) of the forming mold of item F1 is a positioning device provided in the forming mold; and the forming mold is made of material Those who fill the mold cavity 固定 formed between the fixed-side template (4) and the movable-side mold, (5) to form the product. The front holding device is used to hold the fixed-side template and the movable-side template. It is characterized by having: a pin member (12, 41, 45) installed on the fixed-side template or the movable-side template; it is movably disposed on two-sheets at a position further behind the ^^ end (32).
