Description

Technical Field

[0001] The invention relates to an injection mold, in particular to an in-mold inclined top front installation mold. Background Art

[0002] With the rapid development of the manufacturing industry, the demand for talent in the mold industry remains high. High technician salaries contrast sharply with meager product profits. During mold trials, it's common to remove the machine to change or modify the design. However, traditional removal of the lifter requires dismantling the entire rear mold, which is time-consuming and cumbersome, simply to replace the lifter. Consequently, the industry urgently needs a mold and process that reduces labor costs, shortens mold removal time, improves labor efficiency, and simplifies lifter removal.

[0003] We decided to start developing a technology that can disassemble and assemble the mold from the front with an inclined top, improve the efficiency of the overall disassembly and assembly of the mold, and improve the injection efficiency, thereby achieving cost reduction and efficiency improvement. Summary of the Invention

[0004] The purpose of the present invention is to provide an in-mold inclined top front installation mold which simplifies the inclined top disassembly process.

[0005] To achieve the above objectives, the technical solution of the present invention is:

[0006] The present invention is an in-mold inclined top front installation mold, comprising an inclined top, an inclined top fixing block, an inclined top guide block, a spring, and a top plate; grooves are provided on both sides of the lower end of the inclined top, and the lower end of the inclined top is movably sleeved in the groove on the upper part of the inclined top fixing block, the lower part of the inclined top fixing block is movably inserted into the upper part of the inclined top guide block and springs are provided on both sides of the lower part of the inclined top fixing block, and the lower part of the inclined top guide block is installed on the top plate; the inclined top fixing block comprises two fixing clips and a positioning pin; the two fixing clips are arranged in a mirror image, and the middle parts of the two fixing clips are hinged together by the positioning pin, so that a groove is formed on the upper parts of the two fixing clips, and a protrusion is provided on the upper part of the fixing clip. The protrusions on the two fixing clips constitute a buckle, which can be clamped in the grooves on both sides of the lower end of the inclined top.

[0007] The upper part of the inclined top guide block is provided with a U-shaped groove, and a sink groove is provided at the bottom of the U-shaped groove. The lower part of the inclined top guide block is provided with a stepped hole with small ends and large middle. The stepped hole passes through the lower part of the inclined top guide block in the horizontal direction, and the large hole in the middle of the stepped hole is connected with the sink groove; the lower part of the inclined top fixing block passes through the gap after the U-shaped groove of the inclined top guide block and is inserted into the sink groove, and two springs are respectively placed in the large holes of the stepped hole of the inclined top guide block, and the two ends of the spring respectively rest on the fixing clips on the inclined top fixing block and the stepped surface of the stepped hole of the inclined top guide block. The spring can form an inward clamping force on the upper parts of the two fixing clips on the inclined top fixing block, so that the protrusions on the fixing clips are reliably clamped in the grooves on both sides of the lower end of the inclined top.

[0008] The ejector plate is composed of an ejector panel and an ejector bottom plate; the ejector panel and the ejector bottom plate are fixed together, and the lower part of the inclined ejector guide block is installed on the ejector panel.

[0010] Using the above scheme, the present invention includes a lifter, a lifter fixing block, a lifter guide block, a spring, and a lift plate. The lifter fixing block is composed of two fixing clips and a positioning pin. The protrusions on the upper portions of the two fixing clips form a snap that snaps onto the lower portion of the lifter. To replace the lifter, a jig is pushed against the spring, opening the upper end of the lifter fixing block. The fixing clip disengages the protrusions from the groove on the lifter, allowing the lifter to be detached from the fixing block for replacement and disassembly. This reduces time-consuming disassembly and assembly, improves production efficiency, reduces labor costs, and simplifies the lifter disassembly process.

[0019] like Figure 1-Figure 5 As shown, the present invention is an in-mold inclined top front installation mold, including an inclined top 1, an inclined top fixing block 2, an inclined top guide block 3, a spring 4, a top plate 5, and a fixture 6.

[0020] The lower end of the inclined top 1 has grooves 11 on both sides. The lower end of the inclined top 1 is movably sleeved in the slot 20 on the upper part of the inclined top fixing block 2. The lower part of the inclined top fixing block 2 is movably inserted into the upper part of the inclined top guide block 3 and springs 4 are provided on both sides of the lower part of the inclined top fixing block 2. The lower part of the inclined top guide block 3 is mounted on the top plate 5 (as shown in FIG. Figure 6 shown).

[0021] The inclined top fixing block 2 includes two fixing clips 21 and a positioning pin 22; the two fixing clips 21 are arranged in a mirror image, and the middle parts of the two fixing clips 21 are hinged together by the positioning pin 22. The two fixing clips 21 can be opened and closed crosswise along the positioning pin 22, so that a slot 20 is formed on the upper part of the two fixing clips 21, and a protrusion 211 is provided on the upper part of the fixing clip 21. The protrusions 211 on the two fixing clips 21 constitute a buckle, which can be clamped in the grooves 11 on both sides of the lower end of the inclined top 1, and the two ends of the positioning pin 22 are fixed in the pin holes 34 on the inclined top guide block 3.

[0022] The upper part of the inclined top guide block 3 is provided with a U-shaped groove 31, and a sink groove 32 is provided at the bottom of the U-shaped groove 31. The lower part of the inclined top guide block 3 is provided with a stepped hole 33 with small ends and a large middle part. The stepped hole 33 passes through the lower part of the inclined top guide block 3 in the horizontal direction, and the large hole 331 in the middle of the stepped hole 33 is connected with the sink groove 32; the lower part of the inclined top fixing block 2 passes through the U-shaped groove 31 of the inclined top guide block 3 and is inserted into the sink groove 32 with a gap. The two springs 4 are respectively arranged in the large holes 331 of the stepped hole 33 of the inclined top guide block 3, and the two ends of the spring 4 are respectively pressed against the fixing clip 21 on the inclined top fixing block 2 and the stepped surface of the stepped hole 33 of the inclined top guide block 3. The spring 4 can form an inward clamping force on the upper part of the two fixing clips 21 on the inclined top fixing block 2, so that the protrusions 211 on the fixing clip 21 are reliably clamped in the grooves 11 on both sides of the lower end of the inclined top 1.

[0023] The ejector plate 5 is composed of an ejector panel 51 and an ejector bottom plate 52 ; the ejector panel 51 and the ejector bottom plate 52 are fixed together, and the lower portion of the inclined ejector guide block 3 is mounted on the ejector panel 51 .

[0024] The jig 6 can be inserted into the stepped hole 33 of the inclined top guide block 3 from the gaps on both sides and abut against the spring 4 installed in the stepped hole 33 .

[0025] The working principle of the present invention is:.

[0026] like Figure 6 、 Figure 7As shown, the lift guide block 3 is primarily used for installing and guiding the lift 1 and the lift fixing block 2. The two pieces of the lift fixing block 2 intersect and merge, securing the lift 1 in the middle. The two pieces are also secured in the center by a locating pin 22, allowing them to open and close along these pins. Springs 4 are located on either side of the lift guide block 3, flush against the lift fixing block 2, and rest against the ends of the lift fixing block 2. A fixture 6 passes through the lift guide block 3, pushing the springs 4 against the lift fixing block 2, allowing it to move along the lift fixing block 2. Before installation, first install the inclined top fixing block 2, the inclined top guide block 3 and the spring 4 in the top plate 5. At this time, use the jig 6 to pass through the guide block 12 to push the spring 4 to the end of the inclined top fixing block 2 to apply pressure to the upper end of the inclined top fixing block 2, so that the upper end protrusion 211 opens. At this time, when the inclined top 1 moves down to the inclined top fixing block 2 buckle, the groove 11 of the inclined top 1 overlaps with the buckle. At this time, release the jig 6, and the end of the inclined top fixing block 2 loses the force of the spring 4, so that the upper end buckle closes, fixing the inclined top 1 and making it unable to move, so as to carry out production. When the inclined top 1 needs to be replaced, push the jig 6 toward the spring 4 again to open the upper end of the inclined top fixing block 2, and the protrusion 211 of the inclined top fixing block 2 and the groove 11 of the inclined top 1 are separated, so that the inclined top 1 can be detached from the fixing block 13 for replacement and disassembly.

[0027] The above description is merely a preferred embodiment of the present invention and therefore cannot be used to limit the scope of the present invention. In other words, equivalent changes and modifications made according to the scope of the patent application and the contents of the specification should still fall within the scope of the patent of the present invention.
