[0002] Molds are various molds and tools used in industrial production to obtain the desired products by injection molding, blow molding, extrusion, die casting or forging, smelting, stamping and other methods. In short, molds are tools used to shape objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of objects by changing the physical state of the molded material, and is known as the "mother of industry".

[0003] In the design of injection molds, for multi-cavity molds with oblique undercuts on the front mold, it is usually necessary to design a front mold oblique slider structure. However, in the existing mold structure, the spacing between the front mold oblique slider structures is large, which increases the size of the mold and is not conducive to assembly and use. Moreover, it is difficult to set water channels on the existing front mold oblique sliders, which will affect the cooling and heat dissipation of the mold, resulting in a longer product production cycle. Utility Model Content

[0004] The purpose of the utility model is to overcome the deficiencies in the prior art and provide a mold with a front mold oblique slider. The first connecting rod drives the track blocks at both ends of the oblique slider to move horizontally synchronously, while the guide rod moves along the slide groove and the oblique slider moves along the guide column to realize the core pulling and resetting of the front mold insert slider and reduce the spacing between the rows.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0017] Beneficial Effects

[0018] (1) When the track block in the utility model moves, the slide groove thereon can drive the oblique slider to move through the guide rod, and under the action of the guide column, the oblique slider moves along its axial direction to realize the core pulling and resetting of the front mold insert slider; since all the track blocks are synchronously driven by the two first connecting rods, this structure can reduce the spacing between the oblique sliders, reduce the size of the mold, and facilitate assembly and use.

DETAILED DESCRIPTION

[0025] The present invention will now be further described in detail in conjunction with the accompanying drawings and embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0026] Embodiment 1

[0027] like Figure 1-Figure 3 As shown, a mold with a front mold inclined slider includes a hot runner plate 2 and a front mold plate 3 that are overlapped, and a front mold inclined slider structure is arranged between the two, so that the product can be smoothly formed and demolded on the mold.

[0028] The front mold inclined slider structure includes two oppositely arranged first connecting rods 12, which are arranged between the hot runner plate 2 and the front mold plate 3 and can move horizontally synchronously between the two; a plurality of inclined sliders 9 are arranged between the two first connecting rods 12, and the plurality of inclined sliders 9 are evenly spaced between the two first connecting rods 12, and a plurality of front mold insert sliders 11 are installed on each inclined slider 9, and the plurality of front mold insert sliders 11 are also evenly spaced on the inclined slider 9.

[0029] Both ends of the oblique slider 9 are connected to the first connecting rod 12 through a track block 13. A reversely inclined slide groove 14 is provided on the track block 13, and the end of the oblique slider 9 is embedded in the slide groove 14 through a guide rod 15; as the track block 13 moves, the guide rod 15 is driven to slide in the slide groove 14.

[0030] A clearance groove 8 for accommodating the oblique slider 9 is also provided between the hot runner plate 2 and the front template 3. The two parts of the clearance groove 8 are respectively located on the hot runner plate 2 and the front template 3, and their number and position correspond to the number and position of the oblique slider 9. In addition, a positively inclined guide column 10 is provided on the inner side of the clearance groove 8, one end of the guide column 10 is connected to the front template 3, and the other end passes through the oblique slider 9.

[0031] Specifically, the guide post 10 is parallel to the front mold insert slider 11, and is also parallel to the side of the clearance groove 8; after the product in the mold is formed, the first connecting rod 12 is pulled out (with Figure 2 Taking the example of the embodiment of the present invention), the horizontal force is converted into an upward force by using the reversely inclined slide groove 14 on the track block 13, so that the oblique slider 9 is pulled obliquely upward along the guide column 10, completing the action of the front mold insert slider 11 being separated from the oblique buckle of the product; on the contrary, before injection molding, the first connecting rod 12 is pushed forward, and the slide groove 14 on the track block 13 cooperates with the guide rod 15, so that the oblique slider 9 is pushed obliquely downward along the guide column 10, driving the end of the front mold insert slider 11 away from the oblique slider 9 to pass through the front template 3 into the mold cavity.

[0032] Among them, the positive and reverse directions specified above are not limited to designated directions, but are intended to illustrate that the inclination directions of the guide column 10 and the slide groove 14 are opposite, so as to ensure that the structure converts the horizontal movement position into an oblique displacement; the width of the slide groove 14 is the same as the outer diameter of the guide rod 15, that is, the outer circumferential surface of the guide rod 15 is in contact with the two side surfaces of the slide groove 14 at the same time, so as to ensure that the moving distance of the oblique slider 9 is the same during the reciprocating process, thereby ensuring the accuracy of core pulling and resetting.

[0033] As mentioned above, the oblique slider 9 is provided with guide holes corresponding to the positions and numbers of the guide posts 10, one end of the guide post 10 passes through the oblique slider 9 through the guide hole, and a sliding bushing is also provided between the guide post 10 and the oblique slider 9. The guide hole is used to facilitate the guide post 10 to pass through the oblique slider 9 and limit the moving direction of the oblique slider 9. The sliding bushing is made of copper material, which can reduce the friction and wear between the guide post 10 and the oblique slider 9.

[0034] Furthermore, the oblique slider 9 includes a fixed block 91 and a pressing block 92, which overlap with each other, and a guide hole passes through the fixed block 91 and the pressing block 92. This structure can facilitate the installation of the front mold insert slider 11 on the oblique slider 9. One end of the front mold insert slider 11 is installed between the fixed block 91 and the pressing block 92. That is, during installation, the front mold insert slider 11 passes through the fixed block 91, and then the pressing block 92 is fixed to the back side of the fixed block 91. The front mold insert slider 11 is fixedly installed by the pressing block 92.

[0035] The pressing block 92 is also provided with a water channel for cooling the mold, and the water channel is connected to the interior of the front mold insert slider 11; compared with the prior art in which no water channel can be provided on the front mold slider, this structure can also improve the cooling effect of the mold and shorten the product cooling and molding cycle.

[0036] Among them, one end of the guide rod 15 is fixedly connected to the pressure block 92, and the other end is embedded in the slide groove 14; the end embedded in the slide groove 14 can rotate in the slide groove 14 to prevent the guide rod 15 from getting stuck during the sliding process and avoid the two ends of the oblique slider 9 from moving asynchronously.

[0037] Embodiment 2

[0038] On the basis of embodiment one, the utility model also proposes a mold, comprising a front mold assembly and a rear mold assembly that can open and close relative to each other, and a cavity for injection molding is formed between the two after the molds are closed; and a driving assembly for driving the first connecting rod 12 to move horizontally is also provided on the outer side of the front mold assembly, and a common rear mold slider assembly is provided on the rear mold assembly.

[0039] like Figure 1-Figure 3 As shown, the front mold assembly includes a panel 1, a hot runner plate 2, a front mold plate 3 and a front mold push plate 4 which are overlapped in sequence, and the aforementioned front mold inclined slider structure is arranged between the hot runner plate 2 and the front mold plate 3; the rear mold assembly includes a rear mold push plate 5, a rear mold plate 6 and a bottom plate 7 which are overlapped in sequence, and the front mold push plate 4 is in contact with the rear mold push plate 5 when the mold is closed.

[0040] The driving assembly includes a base 18, a support plate 19, a slide plate 20, a support rod 21 and a telescopic assembly 23. The base 18 and the support plate 19 are arranged on one side of the hot runner plate 2 and the front template 3 relative to each other, and the base 18 is fixedly connected to the hot runner plate 2 and the front template 3; the base 18 is fixedly connected to the support plate 19 through the support rod 21, the slide plate 20 is located between the base 18 and the support plate 19, and is slidably mounted on the support rod 21; the telescopic assembly 23 is located between the base 18 and the support plate 19, and the output end of the telescopic assembly 23 is connected to the slide plate 20.

[0041] Specifically, the end of the first connecting rod 12 is fixedly connected to the slide plate 20, and the telescopic component 23 preferably adopts a cylinder, which can be installed on the mold or the support plate 19; when the telescopic component 23 drives the slide plate 20 to move along the support rod 21 close to the mold, the first connecting rod 12 is pushed forward, and the front mold insert slider 11 extends into the cavity to achieve reset; when the telescopic component 23 drives the slide plate 20 to move close to the support plate 19, the first connecting rod 12 is pulled out, and the front mold insert slider 11 performs a core pulling action.

[0042] Furthermore, a second connecting rod 16 is fixedly mounted on the slide plate 20 . The second connecting rod 16 is parallel to the first connecting rod 12 , and a shovel base block 17 capable of leaning against the back side of the oblique sliding block 9 is fixedly mounted on one side of the second connecting rod 16 .

[0043] Based on this, the first connecting rod 12 and the second connecting rod 16 move synchronously. When the front mold insert slider 11 extends to the cavity, the shovel base block 17, driven by the second connecting rod 16, rests on the back of the inclined slider 9 (that is, the side of the pressure block 92 opposite to the front mold insert slider 11), pressing it firmly, thereby preventing the risk of the front mold insert slider 11 moving backward due to the high injection pressure.

[0044] In order to make the structure inside the mold more compact, a groove 22 corresponding to the number and position of the shovel base blocks 17 is opened on the back side of the inclined sliding block 9, and one side of the shovel base block 17 can be embedded in the groove 22.

[0045] Specifically, the groove 22 is opened on the back side of the pressure block 92. When the front mold insert slider 11 extends into the cavity, one side of the shovel base block 17 is embedded in the groove 22, and the bottom surface of the front mold insert slider 11 contacts the bottom surface of the groove 22. This structure can increase the contact area between the shovel base block 17 and the inclined slider 9, so that the position of the front mold insert slider 11 is more stable during the injection molding process.

[0046] Working principle:

[0047] After the product in the mold is formed, it is driven by the telescopic assembly 23 to drive the first connecting rod 12 to advance, and the track block 13 is used to convert the horizontal force into an upward force, so that the oblique slider 9 and the front mold insert slider 11 are simultaneously pulled upward along the guide column 10 to complete the action of disengaging the oblique buckle of the product;

[0048] After the front mold insert slider 11 is cored out, the mold is opened by the injection molding machine, and the rear mold slider assembly retreats under the action of the lever to disengage the undercut around the front mold of the product; when the rear mold slider assembly retreats, the front and rear molds are opened;

[0049] After the front and rear molds are opened, the rear mold push plate 5 is pushed out under the thrust of the ejector rod of the injection molding machine, and the product is ejected under the action of the rear mold push block insert, and then falls freely;

[0050] After the front mold insert slider 11 is reset under the action of the telescopic assembly 23, the shovel base block 17 fixed on the second connecting rod 16 presses the fixing block 91 and the pressing block 92 to prevent the risk of the front mold insert slider 11 moving backward due to high injection pressure.

[0051] In summary, the mold proposed by the utility model has a compact arrangement, can reduce the mold size, has a good mold cooling effect, and is particularly suitable for a multi-cavity mold with an oblique undercut on the front mold.
