Molds capable of solving unilateral slide misalignment

Abstract

This utility model discloses a mold capable of solving unilateral slide misalignment, including a front mold assembly, a rear mold assembly, a side slide member, and an anti-misalignment member. The front mold assembly includes a front mold core; the rear mold assembly includes a rear mold core; the side slide member is disposed between the front mold assembly and the rear mold assembly, and the molding part of the side slide member, the front mold core, and the rear mold core surround to form a molding cavity; the anti-misalignment member includes an anti-misalignment insert, which is disposed between the front mold assembly and the rear mold assembly, opposite to the side slide member, and the side of the anti-misalignment insert facing the side slide member abuts against the front mold core and the rear mold core respectively. Thus, when the front and rear molds are closed, the side slide member and the opposite anti-misalignment insert are simultaneously subjected to balanced forces, thereby avoiding misalignment between the front and rear molds. This not only solves the problem of product clamping step difference caused by unilateral slide misalignment, but also avoids guide post rubbing and burning problems in the mold.

Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a mold that can solve the problem of unilateral displacement. Background Technology

[0002] In the mold manufacturing industry, single-sided sliding molds are one of the commonly used traditional mold structures. Generally, when a product has complex side structures such as side holes and side recesses, a "sliding" structure is needed to assist in molding. A "sliding" is a mold component that slides laterally. When a product only has side structures such as side holes and side recesses that need to be molded, single-sided sliding molds are produced.

[0003] However, traditional single-sided sliding molds have drawbacks. For example, due to the assembly gap between the mold guide pin hole and the guide pin, when the mold is working, the single-sided sliding wear block rubs against the inclined surface of the front mold blank, generating lateral force. This force causes the side sliding component to shift to one side. First, this sliding offset will cause misalignment between the front and rear molds, resulting in a step difference in the product clamping area and affecting the product's appearance quality. Second, the misalignment between the front and rear molds will also intensify the friction between the guide pin and the guide bushing, which may lead to burn-out damage to the guide pin in severe cases. Finally, frequent wear of components such as the guide pin and guide bushing will shorten the overall life of the mold, increasing the mold maintenance frequency and replacement costs. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a mold that can solve the problem of unilateral displacement, thereby improving the mold life and product quality.

[0005] The objective of this utility model is achieved through the following technical solution:

[0007] In one embodiment, the anti-displacement insert includes an anti-displacement front mold portion and an anti-displacement rear mold portion. The anti-displacement front mold portion is located on the front mold assembly, and the anti-displacement rear mold portion is located on the rear mold assembly. The anti-displacement front mold portion is provided with a backhoe structure, and a limiting groove is formed on the front mold core. The backhoe structure abuts against the limiting groove. The side of the anti-displacement insert facing the side slide member is provided with an insert abutting slope, which is connected to the backhoe structure. The side of the rear mold core facing the anti-displacement insert is a rear mold abutting slope, which contacts and abuts against the rear mold abutting slope.

[0008] In one embodiment, the anti-displacement front mold portion is further provided with a mounting protrusion, which is fixed to the front mold assembly by a screw connector.

[0009] In one embodiment, the front mold assembly further includes a front mold frame, the front mold frame includes a front mold blank, the front mold core is mounted on the front mold blank, and a limiting fixing groove is formed on the front mold blank, and the mounting protrusion is mounted in the limiting fixing groove.

[0010] In one embodiment, the rear mold assembly further includes a rear mold frame, the rear mold frame includes a rear mold blank, the rear mold blank is mounted on the rear mold blank, and the rear mold blank has a clearance groove, the anti-displacement rear mold portion on the anti-displacement insert is located in the clearance groove.

[0011] In one embodiment, two anti-displacement inserts are provided, and the two anti-displacement inserts are spaced apart.

[0012] In one embodiment, the system further includes multiple sets of positioning elements, each of which is located around the front mold core and the rear mold core. Each positioning element includes a front mold positioning block and a rear mold positioning block. The front mold positioning block is mounted on the front mold assembly and has a positioning groove. The rear mold positioning block is mounted on the rear mold assembly and has a positioning protrusion.

[0013] In one embodiment, the front mold positioning block is mounted on the front mold assembly via a screw connection, and the rear mold positioning block is also mounted on the rear mold assembly via a screw connection.

[0014] In one embodiment, the positioning elements are provided in three sets, and the three sets of positioning elements are located on the three sides of the front mold core and the rear mold core.

[0015] In one embodiment, the side guide member includes a side guide seat, which is disposed between the front mold assembly and the rear mold assembly, and the side of the side guide seat facing the anti-displacement member is a molding portion.

[0016] Compared with the prior art, the present invention has at least the following advantages:

[0017] This invention addresses the issue of unilateral slide misalignment in a mold by incorporating an anti-misalignment insert between the front and rear mold assemblies. The insert is positioned opposite the side slide member and simultaneously abuts against both the front and rear mold cores, creating a reverse constraint on the side slide member. This ensures that when the front and rear molds close, the side slide member and the opposite anti-misalignment insert experience balanced forces, preventing misalignment. This not only solves the problem of uneven product clamping steps caused by unilateral slide misalignment but also prevents guide post rubbing and burning. Consequently, it extends the mold's lifespan and improves product quality. Attached Figure Description

[0026] To facilitate understanding of this utility model, a more comprehensive description of this utility model will be given below with reference to the accompanying drawings.

[0027] Please see Figures 1-7 As shown, a mold 10 capable of solving unilateral slippage includes: a front mold assembly 100, a rear mold assembly 200, a side slippage component 300, and an anti-slippage component 400. The front mold assembly 100 includes a front mold core 110; the rear mold assembly 200 includes a rear mold core 210; the side slippage component 300 is disposed between the front mold assembly 100 and the rear mold assembly 200, and the molding portion of the side slippage component 300, the front mold core 110, and the rear mold core 210 surround each other to form a molding cavity; the anti-slippage component 400 includes an anti-slippage insert 410, which is disposed between the front mold assembly 100 and the rear mold assembly 200. The anti-slippage insert 410 is disposed opposite to the side slippage component 300, and the side of the anti-slippage insert 410 facing the side slippage component 300 abuts against the front mold core 110 and the rear mold core 210 respectively.

[0028] It should be noted that for molds requiring single-sided sliding elements, problems such as misalignment of the front and rear molds and burn-in of guide pillars often occur. Misalignment refers to the misalignment of the molding cavity formed by the front mold core 110, the rear mold core 210, and the molding parts of the side sliding elements, resulting in clamping misalignment (misalignment of the mating edge surfaces between the molding parts). This leads to stepped differences in the corresponding clamping positions on the product, affecting not only the mold's lifespan but also the product's appearance quality. One implementation method involves adding a balance block and side-locking structure between the front mold base of the front mold assembly 100 and the rear mold base of the rear mold assembly 200 to limit the movement of the front and rear molds; however, this method has minimal improvement effect. Therefore, in this invention, by adding anti-misalignment components 400 to the front mold assembly 100 and the rear mold assembly 200, and by ensuring that the anti-misalignment components 400 and the side sliding components 300 are positioned opposite each other, and that the anti-misalignment inserts 410 simultaneously abut against the front mold core 110 and the rear mold core 210, a reverse constraint is formed on the side sliding components 300 to counteract the generated offset force. This ensures that during the mold closing process, the side sliding components 300 and the opposite anti-misalignment inserts 410 are simultaneously subjected to balanced forces, preventing the side sliding components 300 from being unconstrained. Furthermore, compared to simply using balance blocks and side lock structures, this invention can directly constrain the misalignment of the side sliding components 300, effectively eliminating problems such as misalignment of the front and rear molds, clamping misalignment, and guide post rubbing. This not only improves the service life of the mold but also enhances the production quality of the product.

[0029] See also Figure 2 , Figure 3 , Figure 4 and Figure 7As shown, specifically, the anti-displacement insert 410 includes an anti-displacement front mold part 411 and an anti-displacement rear mold part 412. The anti-displacement front mold part 411 is located on the front mold assembly 100, and the anti-displacement rear mold part 412 is located on the rear mold assembly 200. The anti-displacement front mold part 411 is provided with a backhoe structure 413. A limit groove is provided on the front mold core 110, and the backhoe structure 413 abuts against the limit groove. The side of the anti-displacement insert 410 facing the side slide member 300 is provided with an insert abutting slope 414, which is connected to the backhoe structure 413. The side of the rear mold core 210 facing the anti-displacement insert 410 is the rear mold abutting slope, and the insert abutting slope 414 contacts and abuts against the rear mold abutting slope.

[0030] It should be noted that, by dividing the anti-displacement insert 410 into an anti-displacement front mold part 411 and an anti-displacement rear mold part 412, with the front mold part 411 located on the front mold assembly 100 and the rear mold part 412 located on the rear mold assembly 200, the anti-displacement insert 410 simultaneously abuts against both the front mold core 110 and the rear mold core 210. Specifically, the anti-displacement front mold part 411 has a backhoe structure 413 that engages in the limiting groove of the front mold core 110. The limiting groove can fix the position of the anti-displacement insert 410 and prevent it from being pushed off by the side sliding parts. At the same time, an insert abutting slope 414 is provided on the anti-displacement insert 410. The insert abutting slope 414 abuts against the rear mold abutting slope of the rear mold core 210. When the mold is closed, the two slopes are in close contact, thereby canceling the displacement force of the side sliding parts and achieving balance, so as to avoid misalignment of the front and rear molds and thus avoid the problem of guide post burning. In this embodiment, the inclination angle of the insert against the inclined surface 414 is 10-20°, preferably 15°.

[0031] Please see Figure 6 and Figure 7 As shown, the anti-displacement front mold part 411 is further provided with a mounting protrusion 415, which is fixed to the front mold assembly 100 by a screw connector. This allows the anti-displacement insert 410 to be detachably connected to the front mold assembly 100. In this embodiment, the front mold assembly 100 also includes a front mold frame 120, which includes a front mold blank 121. The front mold core 110 is mounted on the front mold blank 121, and a limiting fixing groove 121a is formed on the front mold blank 121. The mounting protrusion 415 is installed in the limiting fixing groove 121a. The limiting fixing groove 121a limits the mounting of the mounting protrusion 415, thereby ensuring that the anti-displacement insert 410 remains stable and does not loosen or shift when subjected to long-term sliding thrust.

[0032] In one embodiment, the side of the anti-displacement insert 410 furthest from the side slide member is a "V"-shaped surface. That is, the side opposite to the insert's abutting inclined surface 414 is not a plane, but a "V"-shaped surface composed of two surfaces. The boundary between the two surfaces is the interface between the front and rear molds, and the two surfaces abut against the front mold blank and the rear mold blank, respectively. In this way, the anti-displacement effect can be further enhanced, avoiding back-and-forth movement due to the slide thrust, and also assisting in the alignment of the front and rear molds, reducing the risk of overall misalignment of the front and rear molds.

[0033] Furthermore, the rear mold assembly 200 also includes a rear mold base 220, which includes a rear mold blank 221. The rear mold blank 221 is mounted on the rear mold blank 221, and a clearance groove is provided on the rear mold blank 221. The anti-displacement rear mold portion 412 on the anti-displacement insert 410 is located in the clearance groove. By providing the clearance groove, after mold closing, the rear mold portion 412 of the anti-displacement insert 410 is accommodated in the clearance groove. The clearance groove prevents the rear mold portion 412 from interfering with the rear mold blank 221. At the same time, the clearance groove contour can also limit the positional displacement of the rear mold portion 412 of the anti-displacement insert 410, so that the rear mold abutting slope and the insert abutting slope 414 are tightly abutted, limiting the misalignment of the front and rear molds.

[0034] Please see Figure 4 and Figure 5 As shown, two anti-displacement inserts 410 are provided, and the two anti-displacement inserts 410 are spaced apart. In this embodiment, there are two side sliding members, so there are also two corresponding anti-displacement inserts 410. The two anti-displacement inserts 410 correspond to the two side sliding members respectively, thereby ensuring uniform and balanced force distribution.

[0035] Please see Figure 3 , Figure 4 and Figure 5 As shown, the mold 10, which can solve the problem of unilateral displacement, also includes multiple sets of positioning components 500. Each positioning component 500 is located around the front mold core 110 and the rear mold core 210. The positioning component 500 includes a front mold positioning block 510 and a rear mold positioning block 520. The front mold positioning block 510 is installed on the front mold assembly 100 and has a positioning groove. The rear mold positioning block 520 is installed on the rear mold assembly 200 and has a positioning protrusion. When the front mold assembly 100 and the rear mold assembly 200 are fastened together, the positioning protrusion is accommodated in the positioning groove.

[0036] It should be noted that the front mold positioning block 510 is installed on the front mold blank 121 and is arranged around the front mold core 110; the rear mold positioning block 520 is installed on the rear mold blank 221 and is arranged around the rear mold core 210. When the mold is closed, the positioning protrusion on the rear mold positioning block 520 is accommodated in the positioning groove of the front mold positioning block 510, thereby further limiting the misalignment of the front and rear molds. It is equivalent to forming a dual positioning by the front mold positioning block 510 and the rear mold positioning block 520, together with the anti-misalignment insert 410, thereby improving the overall positioning accuracy and reducing the risk of misalignment of the front and rear molds.

[0037] In one embodiment, the front mold positioning block 510 is mounted on the front mold assembly 100 via screws, and the rear mold positioning block 520 is also mounted on the rear mold assembly 200 via screws. This allows for a detachable connection between the front mold positioning block 510 and the rear mold positioning block 520, facilitating maintenance and replacement without requiring a complete replacement of the mold frame, thereby significantly reducing mold maintenance costs.

[0038] Furthermore, three sets of positioning components 500 are provided, located on the three sides of the front mold core 110 and the rear mold core 210. This means that while the side sliding component 300 occupies one side, the three sets of positioning components 500 occupy the other three sides, avoiding the side sliding component 300. Simultaneously, the three sets of positioning components 500 also form a triangular positioning system, further reducing the risk of misalignment between the front and rear molds during mold closing and preventing product clamping differences.

[0039] In one embodiment, the side sliding member 300 includes a side sliding seat, which is disposed between the front mold assembly 100 and the rear mold assembly 200. The side of the side sliding seat facing the anti-displacement member 400 is a molding part, which mainly shapes the side structure of the product. In addition, the side sliding member 300 also includes inclined guide pillars, guide blocks, guide rails, wear-resistant blocks, and other structures. The specific structure of the side sliding member 300 is prior art and will not be described in detail here. Furthermore, the mold also includes an ejector demolding structure 600, which is installed on the rear mold assembly 200 to eject and demold the product. The ejector demolding structure can employ prior art.

[0040] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
