Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, and more specifically, to a mold with a novel sliding drive structure. Background Technology

[0002] Common injection molds typically consist of a front mold mechanism and a rear mold mechanism. The front mold mechanism works in conjunction with the rear mold mechanism to open and close the mold. The existing rear mold mechanism usually includes a rear mold blank and sliding parts located around it. These sliding parts are moved not only by the inclined guide pillars of the front mold mechanism but also by hydraulic cylinders or other driving devices to make minor movements on the rear mold plate (especially when the sliding parts are large). This avoids the clearance tolerance issues between the inclined guide pillars and the inclined guide holes on the sliding parts, allowing the sliding parts to move closer to the rear mold blank. However, when some injection molds are only used as temporary molds, equipping each sliding part with a hydraulic cylinder would result in higher mold manufacturing and usage costs. Utility Model Content

[0003] The purpose of this invention is to overcome the above-mentioned defects in the prior art and provide a mold with a novel sliding drive structure, which uses a hydraulic cylinder and connecting rod to drive the sliding movement, thereby saving mold costs.

[0004] To achieve the above objectives, this utility model provides a mold with a novel sliding drive structure, including a front mold mechanism and a rear mold mechanism. The front mold mechanism can open and close the mold with the rear mold mechanism. The front mold plate has a front mold blank located in the middle and four sets of inclined guide pillars around the front mold blank. The rear mold plate has a rear mold blank located in the middle and four sliding parts slidably installed around the rear mold blank. The volume of the two sliding parts located on the side of the rear mold blank in the length direction is larger than the volume of the two sliding parts located on the side of the rear mold blank in the width direction. Each sliding part has an inclined guide hole that mates with the corresponding inclined guide pillar. The front plate has inclined ejector seats on opposite sides along the length direction. The two inclined ejector seats have inclined ejector grooves that are inclined outwards in the direction away from the rear mold mechanism. Two sliding blocks on the side of the mold blank along its length are respectively provided with inwardly inclined hydraulic cylinders in the middle of their outer sides. The output rods of the two hydraulic cylinders can slide in the inclined top grooves of their respective inclined top mating seats. The two outer corners of the four sliding blocks are respectively provided with inclined mounting grooves. A drive link is provided between the inclined mounting grooves of two adjacent sliding blocks. One end of two drive links is fixedly connected to one sliding block on the side of the rear mold blank along its length, and one end of the other two drive links is fixedly connected to another sliding block on the side of the rear mold blank along its length. The two hydraulic cylinders can drive the two sliding blocks on the side of the rear mold blank along its length to move inward toward the rear mold blank. The two sliding blocks on the side of the rear mold blank along its length can also drive the two sliding blocks on the side of the rear mold blank along its width to move inward toward the rear mold blank simultaneously through the drive link.

[0024] like Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, the rear mold mechanism 2 may include a rear template 21 and a rear mold base plate 22. The rear template 21 is mounted on the rear mold base plate 22. The rear template 21 is provided with a rear mold blank 23 located in the middle and four sliding positions 24a, 24b, 24c, and 24d slidably mounted around the rear mold blank 23. The volume of the sliding positions 24a and 24b located on the side of the rear mold blank 23 in the length direction is larger than the volume of the sliding positions 24c and 24d located on the side of the rear mold blank 23 in the width direction. The four sliding positions 24a, 24b, 24c, and 24d are respectively provided with oblique guide holes 26 that cooperate with the corresponding oblique guide posts 17.

[0025] like Figure 6 As shown, the outer middle parts of the row positions 24a and 24b are respectively provided with inwardly inclined (i.e., figure-eight shaped) hydraulic cylinders 25. The heads of the output rods of the two hydraulic cylinders 25 can be configured as T-shaped heads, which can slide in the inclined top grooves of their respective inclined top mating seats 18.

[0026] like Figure 6 and Figure 7As shown, triangular oblique mounting slots 241 are provided at the two outer corners of the four rows 24a, 24b, 24c, and 24d, and square strip-shaped drive linkages 27 are provided between each pair of adjacent rows' oblique mounting slots 241. During installation, one end of each of the two drive rods 27 is placed in one of the two oblique mounting slots 241 of the slide position 24a and fixedly connected to the slide position 24a with screws. The other end of each of the two drive rods 27 is placed in one oblique mounting slot 241 of the slide position 24c and one oblique mounting slot 241 of the slide position 24d. The two drive rods 27 are arranged in a V-shape. One end of each of the other two drive rods 27 is placed in one of the two oblique mounting slots 241 of the slide position 24b and fixedly connected to the slide position 24b with screws. The other end of each of the other two drive rods 27 is placed in another oblique mounting slot 241 of the slide position 24c and another oblique mounting slot 241 of the slide position 24d. The remaining two drive rods 27 are also arranged in a V-shape.

[0027] Preferably, the rear template 21 may also be provided with row limit grooves 211 located at the bottom of the four rows 24 and for the rows to move.

[0028] like Figure 1 , Figure 3 and Figure 6 As shown, in order to facilitate the opening and closing of the front mold mechanism and the rear mold mechanism, straight guide pillars 19 can be provided at the four corners of the front mold plate 11, and correspondingly, straight guide holes 28 are provided at the four corners of the rear mold plate 21, and the straight guide pillars 19 can be inserted into the corresponding straight guide holes 28.

[0029] The working principle of this utility model is as follows:

[0030] When the front mold mechanism 1 and the rear mold mechanism 2 close, the output rods of the two hydraulic cylinders 25 extend, and the inclined guide pins 17 on the front mold plate are inserted into the corresponding inclined guide holes 26 of the four slides 24a, 24b, 24c, and 24d, respectively, driving the four slides 24a, 24b, 24c, and 24d to move closer to the rear mold blank 23. When the four slides 24a, 24b, 24c, and 24d move closer to the rear mold blank 23, the heads of the output rods of the two hydraulic cylinders 25 also just enter the inclined ejector groove 181 of the inclined ejector mating seat 18. The output rods of the two hydraulic cylinders 25 move with the slides... As the moving parts slowly retract, when the front mold mechanism 1 and the rear mold mechanism 2 are ready to close the mold, the output rods of the two hydraulic cylinders 25 extend and abut against the inclined ejector seat 18. Under the reaction force of the two hydraulic cylinders 25, the slides 24a and 24b can be further finely adjusted and moved closer to the rear mold blank 23 to avoid unnecessary gaps and to prevent the slides from backing up during the injection molding process. At the same time, when the slides 24a and 24b move, they can also be pushed inward further closer to the rear mold blank 23 by the four drive linkages 27.

[0031] In summary, this utility model has a novel structure and a reasonable design. The mold only has oil cylinders on two of the larger slides, while the two smaller slides can be driven synchronously by the drive linkages on the two larger slides. This can greatly save mold costs and is particularly suitable for use in some temporary molds or simple molds.

[0032] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
