[0027] In order to make the technical means, creative features, purposes and effects of the utility model easy to understand, the utility model is further described below in combination with specific embodiments.
[0028] The first embodiment of the utility model provides the equipment for preparing the new type of package of piezoelectric transformer (hereinafter referred to as "the equipment"), referring to Figures 1-9 It comprises bottom support 1, vertical block 2, cushion block 3, lower die 4, boss part 5, lower forming cavity 6 of the lower shell of the new type of package of piezoelectric transformer, lower forming cavity 7 of the cover of the new type of package of piezoelectric transformer, lower forming medium flow channel 8, lower through flow channel 9, upper die 10, separation mechanism 11, inner recess 12, upper forming cavity 13 of the lower shell of the new type of package of piezoelectric transformer, upper forming cavity 14 of the cover of the new type of package of piezoelectric transformer, upper forming punch 15 of the lower shell of the new type of package of piezoelectric transformer, upper forming medium flow channel 16, upper through flow channel 17.
[0029] Referring to Figures 1-8As shown, the device includes a square base 1 made of metal. A central hole 1a is provided at the center of the base, penetrating the entire base. This central hole serves both as an insertion hole for the limiting support structure and as a way to prevent negative pressure adsorption during the movement of the release mechanism installed above the base. The base has relatively distributed upright blocks 2, located near the front and rear edges of the square base, and generally symmetrically distributed along the base. The blocks are made of metal to facilitate pressure bearing. The relatively distributed blocks create a relative space on the upper surface of the base, facilitating the installation of the release mechanism. A pad 3 is provided on the top of the upright blocks 2, with the width of the pad 3 approximately the same as the distribution width of the upright blocks (in this embodiment, it will be...). Figure 1 The left and right directions are defined as the length direction. Figure 1 The front and rear directions correspond to the width direction), and the front and rear sides of the pad block 3 are flush with the surface of the upright block away from the detachment mechanism.
[0030] See also Figure 6 The pad block is equipped with a lower mold 4, which is the same size as the pad block, both being rectangular blocks. Figure 7 A rectangular boss 5 is centrally located on the lower mold 4, with rounded chamfers at the corners. Figure 8 As can be seen, a second shallow boss 5a is provided in the boss portion 5. The protrusion height of the second shallow boss 5a is approximately 1-1.5cm, and the edge of the second shallow boss is 2-3cm from the edge of the boss portion. A chamfer structure is provided at the edge of the boss portion. Figure 8 The middle section shows the new piezoelectric transformer lower casing P1 and the new piezoelectric transformer casing cover P2. Figure 7 The lower shell P1 and the upper cover P2 of the new piezoelectric transformer package are omitted.
[0031] See Figure 8As shown, the boss part is provided with a piezoelectric transformer novel packaging lower shell lower forming cavity 6 and a piezoelectric transformer novel packaging cover lower forming cavity 7 which are distributed in a one-word shape. Due to the presence of the second shallow boss, the piezoelectric transformer novel packaging lower shell lower forming cavity 6 and the piezoelectric transformer novel packaging cover lower forming cavity 7 can be distributed at the position of the second shallow boss. The outer shape of the piezoelectric transformer novel packaging lower shell lower forming cavity 6 and the piezoelectric transformer novel packaging cover lower forming cavity 7 matches the piezoelectric transformer novel packaging lower shell and the piezoelectric transformer novel packaging cover. A lower forming medium flow channel 8 which is in communication between the piezoelectric transformer novel packaging lower shell lower forming cavity 6 and the piezoelectric transformer novel packaging cover lower forming cavity 7 is provided. The lower forming medium flow channel is generally semicircular, and the corresponding upper forming medium flow channel together forms a circular forming medium flow channel for the forming material to pass into the respective forming cavities. A separation mechanism 11 which leads to the piezoelectric transformer novel packaging lower shell lower forming cavity 6 and the piezoelectric transformer novel packaging cover lower forming cavity 7 is provided between the vertical blocks. The separation mechanism can separate the respective forming cavities after the piezoelectric transformer novel packaging lower shell and the piezoelectric transformer novel packaging cover are formed. The separation mechanism includes but is not limited to a ejector pin type separation structure. After the upper die separates from the lower die, the ejector pin enters the respective forming cavity to separate the corresponding formed device from the forming cavity.
[0032] The lower die is provided with an upper die 10, as shown in Figure 10 The upper die is provided with an inner recess 12 which cooperates with the boss part. The inner recess is provided with a piezoelectric transformer novel packaging lower shell upper forming cavity 13 which cooperates with the piezoelectric transformer novel packaging lower shell lower forming cavity 6 and a piezoelectric transformer novel packaging cover upper forming cavity 14 which cooperates with the piezoelectric transformer novel packaging cover lower forming cavity 7. The piezoelectric transformer novel packaging lower shell upper forming cavity 13 is provided with a piezoelectric transformer novel packaging lower shell upper forming punch 15. Since the piezoelectric transformer novel packaging lower shell upper forming punch 15 is built-in in the piezoelectric transformer novel packaging lower shell upper forming cavity 13, the piezoelectric transformer novel packaging lower shell upper forming punch 15 has a gap part 13a around the piezoelectric transformer novel packaging lower shell upper forming punch 15 between the piezoelectric transformer novel packaging lower shell upper forming punch 15 and the side wall of the piezoelectric transformer novel packaging lower shell upper forming cavity 13. The piezoelectric transformer novel packaging lower shell upper forming cavity 13 and the piezoelectric transformer novel packaging cover upper forming cavity 14 are provided with an upper forming medium flow channel 16 which is in communication.
[0033] In the present embodiment, the upper forming medium flow channel and the lower forming medium flow channel jointly constitute the forming medium flow channel of the piezoelectric transformer novel package preparation equipment, and the medium entering the mold from the upper mold medium injection port M enters the corresponding forming chamber through the forming medium flow channel. It should be noted that the forming medium flow channel of the piezoelectric transformer novel package preparation equipment has a transition flow channel S adjacent to each forming chamber, and the inner diameter of the transition flow channel gradually decreases towards the forming chamber. This taper structure is beneficial to the rapid entry of the material into the forming chamber, thereby improving the quality of the formed product. This taper structure is beneficial to the molding of small gap chambers with fluid medium at a relatively large pressure without additional pressure.
[0034] The upper mold and the lower mold are provided with a forming medium injection port (here, the upper mold medium injection port M is the forming medium injection port) communicating with the forming medium flow channel and a forming medium supply channel leading from the forming medium injection port to the forming medium flow channel.
[0035] From Figure 7 As can be seen, the lower forming chamber 6 of the piezoelectric transformer novel package lower shell and the lower forming chamber 7 of the piezoelectric transformer novel package cover are arranged in parallel to form a group of forming units. This design maximizes the space utilization efficiency of the mold and also facilitates the simultaneous molding of a group of piezoelectric transformer novel package shells made of the same material. Three groups of lower forming units are arranged in the boss part 5, and of course, more than three groups of forming units can be arranged according to needs. The upper forming chamber 13 of the piezoelectric transformer novel package lower shell and the upper forming chamber 14 of the piezoelectric transformer novel package cover are arranged in parallel to form a group of forming units, and three groups of upper forming units are arranged in the inner recess. In this way, three groups of piezoelectric transformer novel package shell forming structures can be completed on the upper mold and the lower mold.
[0036] In terms of flow channel distribution, the boss part is provided with a lower through-flow channel 9 vertically distributed with the lower forming medium flow channel 8 of each lower forming unit, and the inner recess is provided with an upper through-flow channel 17 vertically distributed with the upper forming medium flow channel 16 of each upper forming unit. Here, the flow channel distance of the W-shaped forming medium flow channel from the end of the stroke can quickly flow the forming medium into the corresponding forming chamber.
[0037] Continuing to refer to Figure 11The forming punch 15 on the lower shell of the new piezoelectric transformer package is generally a rectangular boss with a concave gradient structure on one side. Specifically, the forming punch 15 on the lower shell of the new piezoelectric transformer package has a first rectangular long straight side 15-1 and a second rectangular irregular side 15-3. The two ends of the first rectangular long straight side 15-1 and the second rectangular irregular side 15-3 are the first rectangular short straight side 15-2 and the second rectangular short straight side 15-4, respectively. -3 is provided with a first concave portion 15-3a near the short straight side 15-4 of the second rectangle, and a second concave portion 15-3b is provided near the short straight side 15-2 of the first rectangle on the irregular side 15-3 of the second rectangle. The length of the second concave portion 15-3b is greater than that of the first concave portion 15-3a. The corner of the first concave portion and the second concave portion adopts an arc corner. The upper molding cavity 13 of the new piezoelectric transformer package has a corresponding rectangular inner extension structure at the first concave portion and the second concave portion.
[0038] The lower casing of the new piezoelectric transformer package has an edge step 15a on the forming punch 15. Two triangular protrusions 15a-1 are provided on the edge step 15a on both sides of the first concave portion 15-3a. A triangular protrusion 15a-2 is provided on the second rectangular irregular side 15-3 of the second concave portion 15-3b. These three triangular protrusions allow a triangular embedded structure to be formed along the upper edge step of the new piezoelectric transformer package, ensuring the relevant leads are fixed there and facilitating the pressure cap to press and fix the leads, thus improving the stability of the lead fixation.
[0039] See Figure 9 , Figures 12-13 The lower molding cavity 6 of the new piezoelectric transformer package is generally a rectangular cavity. The shorter side of this rectangular cavity has an L-shaped protrusion 6a. This L-shaped protrusion forms a concave structure within the lower molding cavity 6 for mounting electrode pieces. One of the longer sides of the lower molding cavity 6 is straight, while the other longer side has two rectangular protruding structures to fit the long and short grooves of the lower molding cavity. A square protrusion 6b is installed on this longer side to facilitate the mounting of electrode pieces on the corresponding longer side of the lower molding cavity. At the bottom of the lower molding cavity 6, a ejector pin structure for ejecting the lower molding cavity is visible.
[0040] Those skilled in the art will understand that the above embodiments are specific examples of implementing the present invention, and in practical applications, various changes can be made to them in form and detail without departing from the spirit and scope of the present invention.
