Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, specifically to a structure for replacing the mold core of an injection support rod. Background Technology

[0002] Injection molds are molds used to produce plastic products. They play a vital role in the plastics processing industry. An injection mold is a mold used for injection molding, which involves heating plastic material to a molten state, then injecting it into the mold cavity, and after cooling, forming a product of the desired shape.

[0003] Currently, the structure of the molding cavity in most injection molds is fixed. When producing different types of injection molded parts, multiple injection molds are required, which increases production costs. Although some molds design the cavity area as a replaceable mold core structure, the shaping capability of the slide structure is also fixed, and the types of injection molded parts that can be produced are still greatly limited. Utility Model Content

[0004] The purpose of this invention is to provide a replacement mold core structure for injection molding support rods to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A replacement mold core structure for an injection molding support rod includes:

[0007] The upper mold includes an upper mold body, the bottom of which is provided with an upper mold core slot, and the upper mold core body is fitted into the bottom of the upper mold core slot;

[0008] The lower mold includes a lower mold body, and a lower mold core slot is provided on the upper side of the lower mold body, in which the lower mold core body is fitted.

[0009] The sliding structure includes a first slider and a second slider, which are slidably mounted on both sides of the upper surface of the lower mold body.

[0010] Furthermore, a replacement mold core structure for an injection molding support rod includes:

[0011] The upper mold includes an upper mold body, the bottom of which is provided with an upper mold core slot, and the upper mold core body is fitted into the bottom of the upper mold core slot;

[0012] The lower mold includes a lower mold body, and a lower mold core slot is provided on the upper side of the lower mold body, in which the lower mold core body is fitted.

[0013] The sliding structure includes a first slider and a second slider, which are slidably mounted on both sides of the upper surface of the lower mold body.

[0014] Furthermore, the lower mold body has support side plates fixedly installed on both sides of its bottom by bolts, and a lower mold base plate is fixedly installed on the bottom of the support side plates by bolts. Positioning pins are fixedly installed at the four corners of the upper surface of the lower mold body, and sliding grooves are opened on both sides of the lower mold core slot.

[0015] Furthermore, mounting screw grooves are provided at the four corners of the top of the upper mold core slot and the bottom of the lower mold core slot, and auxiliary slots are provided at both ends of the inner walls on both sides of the upper mold core slot and the lower mold core slot.

[0016] Furthermore, screw holes are interspersed at the four corners of the upper mold core body and the lower mold core body, and mounting bolts are screwed into the screw holes. A first limiting groove is opened at the wall of the screw hole, and a first spring buckle is slidably engaged in the first limiting groove.

[0017] Furthermore, both the first and second sliders have top post slots inserted in the middle, and both the first and second sliders have mounting slots on one side. Mounting plates are installed in the mounting slots and are fixedly installed on one side of the mold cavity top plate. A mold cavity sealing post is fixedly installed on the other side of the mold cavity top plate.

[0018] Furthermore, the top column slot is provided with a second limiting slide groove on both sides, and an unlocking slot is provided on the upper side of the second limiting slide groove. A second spring buckle is slidably installed in the second limiting slide groove. A triangular slot is provided in the second spring buckle in the vertical direction. The mounting plate is provided with buckle grooves on both sides that engage with the second spring buckle.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. The upper mold core body, lower mold core body, and slide structure that constitute the injection molding cavity are all designed as detachable structures. The modular design is optimized so that when producing injection molded parts with small size differences, the original upper mold core body, lower mold core body, slide number one, and slide number two can be directly removed and replaced to form the molding cavity of the new injection molded part. This greatly expands the types of injection molded parts that a single mold can produce without the need to purchase new mold structures.

[0021] 2. The top plate of the mold cavity, which carries the mold cavity sealing pillar, is also designed to be detachable. This allows for the simultaneous replacement of the sealing structures at both ends when changing the upper mold core body or the lower mold core body. The first or second slider is installed on the top plate of the mold cavity by inserting the mounting plate into the mounting slot, and locked by the second spring buckle into the buckle groove. When replacing or disassembling, a metal rod or other tool is inserted into the unlocking slot and probed into the triangular slot. As the metal rod continues to press down, the second spring buckle is forced to retract through the inclined groove of the triangular slot, thus unlocking the mold cavity.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-6In this embodiment of the utility model, a replacement mold core structure for an injection molding support rod includes an upper mold 1, a lower mold 2, and a sliding structure 3. The upper mold 1 includes an upper mold body 101, with an upper mold core slot 104 at the bottom of the upper mold body 101, and an upper mold core body 109 is fitted into the bottom of the upper mold core slot 104. The lower mold 2 includes a lower mold body 201, with a lower mold core slot 205 at the upper side of the lower mold body 201, and a lower mold core body 207 is fitted into the lower mold core slot 205. The sliding structure 3 includes a first slider 301 and a second slider 302, which are slidably fitted onto the two sides of the upper surface of the lower mold body 201.

[0031] Specifically, the upper mold core body 109, lower mold core body 207, and sliding structure 3 that constitute the injection molding cavity are all designed as detachable structures. Modular design optimization allows for the direct removal and replacement of the original upper mold core body 109, lower mold core body 207, first slider 301, and second slider 302 when producing injection molded parts with small size differences, thus forming the molding cavity of the new injection molded part. This greatly expands the types of injection molded parts that a single mold can produce without the need to purchase additional mold structures.

[0032] Example 1

[0033] like Figure 1-6 As shown, in this embodiment, an upper mold base plate 102 is fixedly mounted on the upper side of the upper mold body 101 by bolts. Positioning slots 103 are provided at the four corners of the bottom of the upper mold body 101. Sliding slots 105 are provided on both sides of the upper mold core slot 104, and drive pins 106 are fitted into the sliding slots 105. Support side plates 202 are fixedly mounted on both sides of the bottom of the lower mold body 201 by bolts. A lower mold base plate 203 is fixedly mounted on the bottom of the support side plates 202 by bolts. The upper mold body 201... Positioning pins 204 are fixedly installed at the four corners of the surface, and sliding grooves 206 are opened on both sides of the lower mold core slot 205; top pin slots 303 are inserted in the middle of the first slider 301 and the second slider 302, and mounting slots 304 are opened on one side of the first slider 301 and the second slider 302. Mounting plates 305 are installed in the mounting slots 304, and the mounting plates 305 are fixedly installed on one side of the mold cavity top plate 306. Mold cavity sealing pins 307 are fixedly installed on the other side of the mold cavity top plate 306.

[0034] In this embodiment, when the upper mold body 101 and the lower mold body 201 drive the upper mold core body 109 and the lower mold core body 207 to approach and assemble with each other, the drive pin 106 is inserted into the pin slot 303, forcing the first slider 301 and the second slider 302 to move along with the assembly of the mold until the two sets of mold cavity sealing pins 307 seal both ends of the molding cavity, forming a complete molding cavity, and inserting metal parts such as nuts and threaded sleeves into the mold cavity, so that they can be directly poured into the injection molded part during injection molding.

[0035] like Figure 3-5 As shown, in this embodiment, mounting screw grooves 107 are provided at the four corners of the inner top of the upper mold core slot 104 and the inner bottom of the lower mold core slot 205. Auxiliary slots 108 are provided at both ends of the inner walls on both sides of the upper mold core slot 104 and the lower mold core slot 205. Screw holes 110 are provided at the four corners of the upper mold core body 109 and the lower mold core body 207. Mounting bolts 111 are screwed into the screw holes 110. A first limiting slide groove 112 is provided at the hole wall of the screw hole 110. A first spring buckle 113 is slidably engaged in the first limiting slide groove 112.

[0036] In specific implementation, when replacing the molding cavity, the new upper mold core body 109 and lower mold core body 207 are respectively inserted into the upper mold core slot 104 and the lower mold core slot 205. The mounting bolt 111 is then screwed into the mounting screw groove 107 through the screw hole 110 for fixed installation. At the same time, the top of the mounting bolt 111 has a conical column structure. When screwed into the screw hole 110, the tip will insert into the arc-shaped groove behind the first spring buckle 113. As the mounting bolt 111 is continuously screwed in, the first spring buckle 113 is pushed out and inserted into the auxiliary slot 108, so that the side surface of the mold core and the inner wall of the mold core slot are interlocked. In addition to bolt fixation, the auxiliary buckle provides a limit, improving the stability of the mold core installation. At the same time, when the mounting bolt 111 is removed, the first spring buckle 113 retracts into the mold core under the action of the spring, making it easy to remove.

[0037] Example 2

[0038] Based on Embodiment 1, in order to compensate for the situation in Embodiment 1 where the sliding structures 3 on both sides are not compatible with the new mold cavity after the upper mold core body 109 and the lower mold core body 207 are replaced.

[0039] like Figure 2 , 6 As shown, in this embodiment, the top column slot 303 has a second limiting slide groove 308 on both sides, the second limiting slide groove 308 has an unlocking slot 309 on the upper side, the second limiting slide groove 308 has a second spring buckle 310 slidingly installed in the second limiting slide groove 308, the second spring buckle 310 has a triangular slot 311 inserted in the vertical direction, and the mounting plate 305 has buckle grooves 312 on both sides that engage with the second spring buckle 310.

[0040] In specific implementation, the top plate 306 of the mold cavity, which carries the mold cavity sealing pillar 307, is also designed to be detachable. This facilitates the simultaneous replacement of the sealing structures at both ends when replacing the upper mold core body 109 and the lower mold core body 207. The first slider 301 or the second slider 302 is installed on the top plate 306 of the mold cavity by inserting the mounting plate 305 into the mounting slot 304, and locked by the second spring buckle 310 into the buckle groove 312. When replacing or disassembling, a metal rod or other tool is inserted into the unlocking slot 309 and then into the triangular slot 311. As the metal rod continues to press down, the second spring buckle 310 is forced to retract through the inclined groove of the triangular slot 311, thus unlocking the mold.

[0041] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
