Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a molding mold for products with side holes. Background Art

[0002] Moulds play a very important role in the manufacturing industry. They can mass-produce consistent products without human intervention, thus saving time and labor costs, and the production quality is more stable.

[0003] When producing the shells of electronic products, many shells need to reserve through holes on the side for connecting power cords. When the mold is produced, in order to reserve a through hole, a molding boss needs to be set in the cavity of the lower mold. When the lower mold and the upper mold cooperate to form a cavity, the molding boss presses against the upper mold to form a through hole when the product is molded. In order to ensure the sealing performance between the molding boss and the upper mold and prevent the molding medium from entering between the molding boss and the upper mold, the molding boss needs to fit the upper mold tightly. This causes severe wear between the molding boss and the upper mold, and high maintenance costs.

[0004] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present disclosure, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the prior art, the purpose of the utility model is to provide a molding die for products with side holes, so as to mold products with side holes.

[0006] The technical solution of the utility model is as follows:

[0007] A forming mold for a product with side holes, comprising an upper mold, a core mold arranged on the upper mold and a lower mold cooperating with the upper mold, wherein the core mold is also provided with a forming rod, and a first groove is provided on the side of the core mold to engage the forming rod; along the direction from the lower mold to the upper mold, the forming rod comprises a first rod segment and a second rod segment; a forming boss is provided on the side of the first rod segment; the rod width of the second rod segment gradually decreases, and a first groove segment is provided on the first groove to cooperate with the second rod segment, and the groove width of the first groove segment gradually decreases; wherein, when the core mold cooperates with the lower mold, the forming boss is in contact with the lower mold, and the forming rod is against the lower mold.

[0008] The beneficial technical effects of the utility model are as follows:

[0009] (1) The molding die for the product with side holes in the utility model is provided with a molding rod. The rod width of the second rod section of the molding rod gradually decreases and is inserted into the first groove section. When the core mold moves downward to cooperate with the lower mold, the molding rod presses against the lower mold, and the molding rod, core mold, upper mold and lower mold together form a cavity. In order to ensure the sealing performance of the cavity, the molding rod needs to press tightly against the lower mold. After the molding rod is squeezed from below, the second rod section with a changed rod width will fit more closely with the first groove section, and the contact area between the molding rod and the first groove section is larger, and the force is dispersed. The bearing capacity and compressive resistance of the molding rod are better, and it can adapt to the greater pressure during mold molding. At the same time, the molding rod and the first groove are engaged, which is convenient for disassembly and assembly. The severely worn molding boss is arranged on the molding rod, which can be quickly replaced and repaired, saving time and cost.

[0010] (2) Furthermore, the molding rod includes a third rod segment that is arranged obliquely. The third rod segment that is simultaneously engaged in the first groove and the second groove limits the horizontal position of the upper mold relative to the core mold. At the same time, the third rod segment is arranged obliquely, and when the upper mold moves in the vertical direction relative to the core mold, it must also move synchronously in the horizontal direction. When the mold is closed, the vertical position between the upper mold, the core mold and the lower mold is fixed. That is, the third rod segment limits the horizontal and vertical positions of the upper mold and the core mold, thereby enhancing the connection strength between the upper mold and the core mold.

[0011] (3) Furthermore, a second step is provided on the forming rod. When the core mold cooperates with the lower mold, the second step abuts against the lower mold to quickly locate the relative positions of the core mold and the lower mold. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Figure 1 The exploded structural schematic diagram of the molding die for the product with side holes of the utility model is shown. Figure 2 The schematic diagram of the main structure of the forming rod and the core mold in the forming mold of the product with side holes of the utility model is shown. Figure 1 and Figure 2A molding die for a product with a side hole comprises an upper die 1, a core die 2 arranged on the upper die 1, and a lower die 4 matched with the upper die 1. A molding rod 3 is also arranged on the core die 2, and a first groove 21 is provided on the side of the core die 2 to clamp the molding rod 3. Along the direction from the lower die 4 to the upper die 1, the molding rod 3 comprises a first rod segment 35 and a second rod segment 33. A molding boss 36 is provided on the side of the first rod segment 35. The rod width of the second rod segment 33 gradually decreases, and a first groove segment 211 is provided on the first groove 21 to match the second rod segment 33, and the groove width of the first groove segment 211 gradually decreases. Among them, when the core die 2 cooperates with the lower die 4, that is, the core die 2 extends into the cavity 41 of the lower die 4, the molding boss 36 fits the lower die 4, and the molding rod 3 abuts the lower die 4. And the molding rod 3 abuts the lower die 4, and the molding rod 3, the core die 2, the upper die 1 and the lower die 4 are surrounded to form a cavity. In order to ensure the sealing performance of the cavity, the molding rod 3 needs to be tightly against the lower die 4. After the forming rod 3 is squeezed from below, the second rod section 33 with a changed rod width will fit more closely with the first groove section 211, and the contact area between the forming rod 3 and the first groove section 211 is large, so the force is dispersed, and the bearing capacity and pressure resistance of the forming rod 3 are good, which can adapt to the greater pressure during mold forming. At the same time, the forming rod 3 and the first groove 21 are engaged, which is convenient for disassembly and assembly. The severely worn forming boss 36 is set on the forming rod 3, which can be quickly replaced and repaired, saving time and cost.

[0019] The specific structure of the forming rod 3 is described below:

[0020] Please refer to Figure 1 and Figure 2 The forming rod 3 also includes a third rod segment 31, which is arranged at one end of the second rod segment 33 close to the upper mold 1. The third rod segment 31 is inclined, and the third rod segment 31 has an angle with the vertical direction. The first groove 21 includes an inclined second groove segment 212, and the second groove segment 212 cooperates with the third rod segment 31. The inclined third rod segment 31 and the core mold 2 can transmit horizontal and vertical forces, increase the area of ​​force transmission between the forming rod 3 and the first groove 21, and disperse the force.

[0021] Please refer to Figure 1 and Figure 2 , a first step 34 is formed between the first rod segment 35 and the second rod segment 33. When the core mold 2 cooperates with the lower mold 4, the first step 34 forms the cavity wall of the cavity. A second step 32 is formed between the second rod segment 33 and the third rod segment 31. When the core mold 2 cooperates with the lower mold 4, the second step 32 abuts against the lower mold 4. Through the first step 34 and the second step 32, the position of the molding rod 3 relative to the lower mold 4 can be quickly located, and the position of the core mold 2 connected to the molding rod 3 can be quickly located.

[0022] The specific structure of the upper mold 1 is described below:

[0023] Please refer to Figure 1and Figure 2 , a through hole 13 is provided on the upper mold 1, the core mold 2 is arranged in the through hole 13, and the second groove 11 is arranged on the hole wall of the through hole 13. The forming rod 3 is simultaneously inserted into the first groove 21 and the second groove 11. Among them, the second groove 11 is arranged at an angle to cooperate with the third rod segment 31 of the forming rod 3. The third rod segment 31 inserted into the first groove 21 and the second groove 11 at the same time limits the horizontal position of the upper mold 1 relative to the core mold 2. At the same time, the third rod segment 31 is arranged at an angle, and when the upper mold 1 moves in the vertical direction relative to the core mold 2, it must also move synchronously in the horizontal direction. When the mold is closed, the vertical position between the upper mold 1, the core mold 2 and the lower mold 4 is fixed. That is, the third rod segment 31 limits the position of the upper mold 1 and the core mold 2 in the horizontal and vertical directions, thereby enhancing the connection strength between the upper mold 1 and the core mold 2.

[0024] Please refer to Figure 1 A support angle 12 is provided at one end of the upper mold 1 close to the lower mold 4, and a positioning groove 42 is provided on the lower mold 4 to cooperate with the support angle 12 to ensure that the relative position of the upper mold 1 and the lower mold 4 is accurate.

[0025] The specific working process of the utility model is as follows:

[0026] First, insert the forming rod 3 into the first groove 21 from the side, and the second rod segment 33 cooperates with the first groove segment 211. Then move the core mold 2 and the forming rod 3 from bottom to top, and insert the third rod segment 31 into the second groove 11. Subsequently, the upper mold 1 moves downward, driving the core mold 2 and the forming rod 3 to move downward synchronously. Until the support angle 12 of the upper mold 1 is inserted into the positioning groove 42 of the lower mold 4, the upper mold 1 and the lower mold 4 are closed. At this time, the lower end of the forming rod 3 is against the lower mold 4, the second step 32 is against the lower mold 4, the forming boss 36 is in contact with the lower mold 4, the forming rod 3 is pushed upward, and the second rod end and the first groove segment 211 are tightly matched and clamped to each other.

[0027] When the molding boss 36 is seriously worn and needs to be replaced, the molding rod 3 is taken out from the second groove 11 from top to bottom, and the molding rod 3 is taken out from the first groove 21 from the side. After replacing a different molding rod 3, the molding rod 3 is inserted into the first groove 21 from the side, and the second rod segment 33 cooperates with the first groove segment 211, and then the core mold 2 and the molding rod 3 are moved from bottom to top, and the third rod segment 31 is inserted into the second groove 11. The maintenance of the molding boss 36 is completed.

[0028] It can be seen that in the above-mentioned molding die for the product with side holes, the severely worn molding boss 36 is arranged on the molding rod 3, which can be quickly replaced and repaired, saving time and cost.
