Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to a mold with a sliding structure. Background Art

[0002] Injection molding refers to the production method of injecting completely molten plastic materials into the mold cavity with high pressure, and then cooling and solidifying to obtain a molded product. It is widely used in the production of plastic products. In the injection molding process, the most common mold opening method for products with undercut structures on the side after injection molding is to open the side slide mold. During the slide mold opening process, the slide slides to one side as the front mold opens, thereby separating from the product.

[0003] In the related art, since the front mold will be completely separated from the slide structure after opening to a certain position, the position and state of the slide structure after separation are difficult to control. Therefore, it is usually necessary to set a first elastic member in the mold to limit the opened slide to avoid mold collision accidents.

[0004] However, in a mold structure with a longer travel distance, the size of the first elastic member also needs to be increased. In order to prepare sufficient working and installation space for the first elastic member, the mold occupies a large space and has a more complex structure, which makes installation and maintenance difficult. Utility Model Content

[0005] In view of this, the utility model provides a mold with a slide structure to solve the problem that the mold with the slide structure occupies a large space and has a complex structure, which leads to difficulties in installation and maintenance.

[0006] The utility model provides a mold with a sliding structure, comprising: a second mold base; a first mold base, which is arranged opposite to the second mold base and moves in a direction close to or away from the second mold base; a sliding structure, comprising a sliding seat and a sliding block installed on the sliding seat, and the sliding seat is slidably matched with the second mold base; a driving structure, which is arranged on the first mold base and drives the sliding structure to slide under the drive of the first mold base; a limiting structure, comprising a limiting seat, a limiting rod and a first elastic member, the limiting seat is arranged on the outer peripheral side wall of the second mold base and is provided with a limiting plate, the limiting rod is arranged on the side wall of the sliding seat facing the outer side of the second mold base, the limiting rod extends to the outer side of the second mold base and passes through the limiting plate, the end of the limiting rod away from the sliding seat is provided with a limiting block, and the first elastic member is located between the limiting block and the limiting plate.

[0007] Beneficial effect: By arranging the limit rod and the first elastic member on the side wall of the sliding seat facing the outside of the second mold base and extending out of the second mold base, when the mold is opened, the first mold base moves away from the second mold base and drives the driving structure, so that the driving structure drives the sliding structure to move to the outside of the second mold base, until the driving result moves with the first mold base to a state of separation from the sliding structure, the first elastic member is always in an elastic deformation state, and always applies elastic force to the sliding seat, resulting in a tendency to keep the sliding seat away from the product, avoiding mold collision accidents caused by the rebound of the sliding seat. At the same time, since the limit seat, the limit rod and the first elastic member are all located on the outside of the second mold base, the space inside the mold is effectively saved, the mold volume is reduced and the structure inside the mold is simplified, achieving the effect of easy installation and easy maintenance.

[0008] In an optional embodiment, the driving structure includes a shovel base and an inclined guide column, the shovel base is installed on the first mold base, the inclined guide column is installed on the shovel base, the end of the inclined guide column away from the first mold base is inclined toward the mold opening direction of the sliding seat, and a guide hole adapted to the inclined guide column is opened on the sliding seat.

[0009] Beneficial effect: By setting a shovel base and an inclined guide column, the shovel base is installed on the first mold base and moves synchronously with the first mold base. During the mold opening process, the first mold base moves away from the second mold base, and the shovel base moves with the first mold base, so that the inclined guide column pushes the hole wall of the guide hole toward the outside of the second mold base, and then pushes the slide seat to move toward the outside of the second mold base, thereby realizing the mold opening action of the slide block.

[0010] In an optional embodiment, the circumferential side walls of the shovel base opposite to the slider seat are both arranged as inclined surfaces, and the lower side of the inclined surface is inclined toward the mold opening direction of the slider seat.

[0011] Beneficial effect: By setting the circumferential side wall opposite to the shovel base and the slider seat as an inclined surface, when the shovel base moves with the first mold seat, the circumferential side wall abutting the shovel base and the slider seat are quickly separated, thereby reducing friction resistance, reducing the wear rate of the structure, and improving the life of the structure.

[0012] In an optional embodiment, the shovel base has a mounting hole adapted to the inclined guide column, the inclined guide column has a positioning block at one end close to the first mold base, the shovel base is provided with a positioning groove adapted to the positioning block at the opening of the mounting hole close to the first mold base, and the side of the shovel base close to the first mold base is connected to the first mold base through a fastener.

[0013] Beneficial effect: the inclined guide column penetrates into the shovel base from the side close to the first mold base when the shovel base is installed. When the positioning block enters the positioning groove and engages with the positioning groove, the inclined guide column reaches the specified position and cannot move forward. The shovel base is then connected to the first mold base through fasteners, so that the first mold base blocks the orifice of the mounting hole and the inclined guide column cannot exit the mounting hole, thereby realizing the positioning and installation of the inclined guide column.

[0014] In an optional embodiment, a wear-resistant plate is provided between the circumferential side walls of the shovel base and the sliding seat opposite to each other.

[0015] Beneficial effect: By setting the wear-resistant plate, the wear between the shovel base and the sliding seat is further reduced, and the service life of the structure is improved.

[0016] In an optional embodiment, the slider block is mounted on the slider seat by a fastener, and the fastener penetrates from a side of the slider seat away from the slider block and is respectively connected to the slider seat and the slider block.

[0017] Beneficial effects: The slider block and the slider seat are connected by fasteners inserted from one side of the slider seat, which avoids the fasteners from affecting the shape of the mold cavity part composed of the slider block and the sealing degree of the mold cavity. At the same time, it is convenient for the staff to observe and repair the looseness of the fasteners from the outside of the mold, thereby improving convenience.

[0018] In an optional embodiment, the second mold base has positioning holes on opposite sides of the slider seat in the movement direction, a positioning pin is provided in the positioning hole, a second elastic member is provided between the positioning pin and the bottom of the positioning hole, and the slider seat has a first positioning groove and a second positioning groove, when the slider seat is in the open mold state, the positioning pin extends into the first positioning groove, and when the slider seat is in the closed mold state, the positioning pin extends into the second positioning groove.

[0019] Beneficial effect: Through the arrangement of the locating pin and the second elastic member, when the slide seat is located at the mold closing position, the locating pin is inserted into the second locating groove to assist in positioning the slide seat. At the same time, the sound of the locating pin inserted into the second locating groove can help the staff judge the working status of the slide structure. In addition, when the slide seat is located at the mold opening position, the locating pin is inserted into the first locating groove to assist in positioning the slide seat, thereby increasing the resistance that the slide seat needs to overcome for rebound, and further reducing the possibility of a mold collision accident caused by the rebound of the slide seat.

[0020] In an optional embodiment, the second mold base includes a base body and a plurality of structural plates installed on the base body, the plurality of structural plates are arranged on both sides of the sliding seat in the moving direction, and the positioning holes are opened on the structural plates.

[0021] Beneficial effect: By setting the positioning holes on the structural plate and then installing the structural plate on the base body, it is avoided that the holes need to be processed in a small space during the mold processing process, which reduces the process difficulty and improves the processing speed of the mold.

[0022] In an optional embodiment, it further includes a travel switch installed on the outer side wall of the second mold base, and a paddle is provided on the side wall of the slide seat facing the outer side of the second mold base, and the paddle triggers the travel switch when the slide seat is in the mold opening position.

[0023] Beneficial effect: By setting a travel switch, during the mold opening process, when the slide seat reaches the mold opening position, the travel switch is triggered, and the travel switch is electrically connected to the control system of the mold, thereby transmitting the information that the slide seat reaches the mold opening position to the control system, which is convenient for the staff to judge and detect the working status of the mold, and is conducive to the automation of mold control. At the same time, a travel switch with a mechanical structure is used as a component for judging the position of the slide seat and sending signals to the control system. Compared with other forms of sensors such as ranging sensors and photoelectric gates, it has lower cost and simpler structure.

[0024] In an optional embodiment, an adjustment seat is installed on the second mold base, and the adjustment seat has an adjustment groove extending along the mold opening direction of the slide seat, and the travel switch is slidably matched with the adjustment groove and is positioned and connected by a fastener.

DETAILED DESCRIPTION

[0035] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0036] Injection molding uses high pressure to inject molten plastic into a mold cavity, and the mold cavity is generally formed by splicing the cavities of a front mold and a rear mold. When the side of the product to be injection molded has an undercut structure, it is difficult to splice the cavities of the front mold and the rear mold to form the shape of the product. Therefore, it is necessary to add a slide structure. The cavity of the front mold, the rear mold, and the slide structure together constitute the mold cavity to meet the shape requirements of the product.

[0037] When the injection mold with a slide structure is opened, the front mold and the rear mold are separated and move away from each other. At the same time, the slide structure is driven by the front mold to move to a side perpendicular to the movement direction of the front mold and the rear mold and in a direction away from the product, thereby realizing the mold opening action. However, since the slide is not directly connected to the driving structure or frame of the mold, when the front mold and the rear mold are opened to a certain extent, the front mold and the slide structure are completely separated, so that the limit of the slide structure fails. The slide structure may collide with other structures under the action of inertia. In order to avoid this situation, it is generally necessary to add elastic parts to continue to limit the slide structure after the front mold and the slide structure are separated.

[0038] However, the size of the elastic part needs to be compatible with the movement stroke of the slide structure, and the movement stroke of the slide structure is affected by factors such as the specific structure of the mold and the specific structure of the product, and is different in different molds. When the movement stroke of the slide structure is longer, the size of the elastic part is larger. In order to reserve installation space for the elastic part in the mold, the mold structure is often bloated and complicated, resulting in difficulties in installation and maintenance.

[0039] The present application proposes a mold with a sliding structure. By arranging the elastic parts and related structures for limiting the sliding structure on the outside of the mold base, there is no need to arrange a complex structure inside the mold to provide an installation basis for the elastic parts. On the one hand, the mold volume is reduced and the mold weight is reduced. On the other hand, the mold structure is simplified, which facilitates the assembly, installation and maintenance of the mold.

[0040] Combine the following Figures 1 to 6 , describing an embodiment of the utility model.

[0041] For the convenience of description, in the following embodiments, each technical feature is Figure 1 The direction in which the first mold base 200 is away from the second mold base 100 is referred to as “upward”, and the description is made with the direction in which the first mold base 200 is close to the second mold base 100 being referred to as “downward”.

[0042] According to an embodiment of the present invention, on the one hand, a mold with a slide structure is provided, see Figures 1 to 3, including a second mold base 100, a first mold base 200, a slide structure 300, a driving structure 400 and a limiting structure 500, wherein the first mold base 200 is arranged opposite to the second mold base 100 and moves in a direction close to or away from the second mold base 100; the slide structure 300 includes a slide seat 301 and a slide block 302 installed on the slide seat 301, and the slide seat 301 is slidably matched with the second mold base 100; the driving structure 400 is arranged on the first mold base 200, and drives the slide structure 300 to slide under the drive of the first mold base 200 The limiting structure 500 includes a limiting seat 501, a limiting rod 502 and a first elastic member 503. The limiting seat 501 is arranged on the outer peripheral side wall of the second mold base 100 and is provided with a limiting plate 5011. The limiting rod 502 is arranged on the side wall of the sliding seat 301 facing the outer side of the second mold base 100. The limiting rod 502 extends to the outer side of the second mold base 100 and passes through the limiting plate 5011. The end of the limiting rod 502 away from the sliding seat 301 has a limiting block 5021, and the first elastic member 503 is located between the limiting block 5021 and the limiting plate 5011.

[0043] Specifically, the limiting rod 502 and the limiting block 5021 can be integrally arranged, or they can be separately arranged and installed together. In the case where the limiting rod 502 and the limiting block 5021 are integrally arranged, for example, a limiting bolt is used as the limiting member here, the rod of the limiting bolt serves as the limiting rod 502, the end of the limiting bolt serves as the limiting block 5021, the first elastic member 503 uses a compression spring and is sleeved on the circumference of the rod of the limiting bolt, and a gasket is provided at the end of the limiting bolt, so as to improve the contact stability with the first elastic member 503.

[0044] It should be noted that the present application does not limit the specific structure of the sliding fit between the slider 301 and the second mold base 100. The slider 301 can be slidably matched with the second mold base 100 through the cooperation of the slider and the slide groove. Exemplarily, the cross-section of the slider 301 is set to be T-shaped, and a T-shaped groove adapted to the slider 301 is provided on the second mold base 100; in some embodiments not shown, the slider 301 and the second mold base 100 can also achieve sliding fit through the cooperation of guide columns and guide holes, and can also achieve sliding fit through a guide rail structure.

[0045] In this embodiment, by arranging the limiting rod 502 and the first elastic member 503 on the side wall of the slide seat 301 facing the outer side of the second mold base 100 and extending out of the second mold base 100, when the mold is opened, the first mold base 200 moves away from the second mold base 100 and drives the driving structure 400, so that the driving structure 400 drives the slide structure 300 to move toward the outer side of the second mold base 100, until the driving result moves with the first mold base 200 to a state of being separated from the slide structure 300, the first elastic member 503 is always in an elastic deformation state, and always applies elastic force to the slide seat 301, generating a tendency to move the slide seat 301 away from the product, thereby avoiding a mold collision accident caused by the rebound of the slide seat 301. At the same time, since the limiting seat 501, the limiting rod 502 and the first elastic member 503 are all located outside the second mold base 100, the space inside the mold is effectively saved, the mold volume is reduced and the structure inside the mold is simplified, so as to achieve the effect of easy installation and easy maintenance.

[0046] See also Figure 3 to Figure 4 In one embodiment, the driving structure 400 includes a shovel base 401 and an inclined guide column 402. The shovel base 401 is installed on the first mold base 200, and the inclined guide column 402 is installed on the shovel base 401. The end of the inclined guide column 402 away from the first mold base 200 is inclined toward the mold opening direction of the slider seat 301, and the slider seat 301 is provided with a guide hole 3011 adapted to the inclined guide column 402.

[0047] In this embodiment, a shovel base 401 and an inclined guide column 402 are provided, the shovel base 401 is installed on the first mold base 200 and moves synchronously with the first mold base 200. During the mold opening process, the first mold base 200 moves in a direction away from the second mold base 100, and at the same time, the shovel base 401 moves with the first mold base 200, so that the inclined guide column 402 pushes the hole wall of the guide hole 3011 toward the outside of the second mold base 100, thereby pushing the slider seat 301 to move toward the outside of the second mold base 100, thereby realizing the mold opening action of the slider block 302.

[0048] In one embodiment, the peripheral side walls of the shovel base 401 opposite to the slider seat 301 are both configured as inclined surfaces, and the lower side of the inclined surface is inclined toward the mold opening direction of the slider seat 301 .

[0049] In this embodiment, by setting the circumferential side wall opposite to the shovel base 401 and the slider seat 301 as an inclined surface, when the shovel base 401 moves with the first mold base 200, the circumferential side wall abutting the shovel base 401 and the slider seat 301 is quickly separated, thereby reducing friction resistance, reducing the wear rate of the structure, and improving the life of the structure.

[0050] In one embodiment, the shovel base 401 has a mounting hole 4011 adapted to the inclined guide column 402, and the end of the inclined guide column 402 close to the first mold base 200 has a positioning block 4021. The shovel base 401 is located at the opening of the mounting hole 4011 close to the first mold base 200 and is provided with a positioning groove 4012 adapted to the positioning block 4021. The side of the shovel base 401 close to the first mold base 200 is connected to the first mold base 200 through fasteners.

[0051] In this embodiment, the inclined guide column 402 penetrates into the shovel base 401 from the side close to the first mold base 200 when the shovel base 401 is installed. When the positioning block 4021 enters the positioning groove 4012 and engages with the positioning groove 4012, the inclined guide column 402 reaches the specified position and cannot move forward. Then, the shovel base 401 is connected to the first mold base 200 through fasteners, so that the first mold base 200 is blocked at the opening of the mounting hole 4011, making it impossible for the inclined guide column 402 to exit the mounting hole 4011, thereby realizing the positioning and installation of the inclined guide column 402.

[0052] In one embodiment, a wear-resistant plate 600 is provided between the circumferential side walls of the shovel base 401 and the slider seat 301 that are opposite to each other.

[0053] Specifically, the wear-resistant plate 600 can be made of a wear-resistant material with a smooth surface, such as a wear-resistant alloy steel plate with a polished surface. The wear-resistant plate 600 can also be made of a soft material, such as a resin sheet with a polished surface, so as to reduce the wear on the side wall of the shovel base 401 or the side wall of the sliding seat 301. The specific materials of the above-mentioned wear-resistant plate 600 are all within the protection scope of this embodiment.

[0054] It should be noted that the wear plate 600 can be connected to the shovel base 401 through fasteners. In some embodiments not shown, the wear plate 600 can also be connected to the side wall of the sliding seat 301 through fasteners. The fasteners can be screws, bolts or other parts with a locking function.

[0055] In this embodiment, by providing the wear-resistant plate 600, the wear between the shovel base 401 and the sliding seat 301 is further reduced, thereby improving the service life of the structure.

[0056] In one embodiment, the slider block 302 is mounted on the slider seat 301 by fasteners. The fasteners penetrate from a side of the slider seat 301 away from the slider block 302 and are connected to the slider seat 301 and the slider block 302 respectively.

[0057] In this embodiment, the slider block 302 and the slider seat 301 are connected by fasteners inserted from one side of the slider seat 301, so as to avoid the fasteners from affecting the shape of the mold cavity part composed of the slider block 302 and the sealing degree of the mold cavity. At the same time, it is convenient for the staff to observe and repair the looseness of the fasteners from the outside of the mold, thereby improving convenience.

[0058] See also Figures 4 to 5 In one embodiment, the second mold base 100 has positioning holes 1011 on opposite sides of the slider seat 301 in the movement direction, a positioning pin 1013 is provided in the positioning hole 1011, a second elastic member 1012 is provided between the positioning pin 1013 and the bottom of the positioning hole 1011, and the slider seat 301 has a first positioning groove 3012 and a second positioning groove 3013. When the slider seat 301 is in the mold opening state, the positioning pin 1013 extends into the first positioning groove 3012, and when the slider seat 301 is in the mold closing state, the positioning pin 1013 extends into the second positioning groove 3013.

[0059] In the present embodiment, through the arrangement of the positioning pin 1013 and the second elastic member 1012, when the slider seat 301 is located at the mold closing position, the positioning pin 1013 is inserted into the second positioning groove 3013 to assist in positioning the position of the slider seat 301. At the same time, the sound of the positioning pin 1013 inserted into the second positioning groove 3013 can help the staff to judge the working state of the slider structure 300. In addition, when the slider seat 301 is located at the mold opening position, the positioning pin 1013 is inserted into the first positioning groove 3012 to assist in positioning the position of the slider seat 301, thereby increasing the resistance that the slider seat 301 needs to overcome in its rebound, and further reducing the possibility of a mold collision accident caused by the rebound of the slider seat 301.

[0060] In one embodiment, the second mold base 100 includes a base body and a plurality of structural plates 101 mounted on the base body. The plurality of structural plates 101 are disposed on both sides of the slide base 301 in the moving direction. The positioning holes 1011 are opened on the structural plates 101 .

[0061] In this embodiment, by setting the positioning hole 1011 on the structural plate 101 and then installing the structural plate 101 on the base body, it is avoided that the hole needs to be processed in a small space during the mold processing process, thereby reducing the process difficulty and improving the processing speed of the mold.

When the slide seat 301 is in the mold opening position, the paddle 3014 triggers the travel switch 700.

[0063] In this embodiment, by setting a travel switch 700, during the mold opening process, when the slider seat 301 reaches the mold opening position, the travel switch 700 is triggered, and the travel switch 700 is electrically connected to the control system of the mold, so that the information that the slider seat 301 reaches the mold opening position is transmitted to the control system, which is convenient for the staff to judge and detect the working state of the mold, and is conducive to the automation of mold control. At the same time, the travel switch 700 with a mechanical structure is used as a component for judging the position of the slider seat 301 and sending signals to the control system. Compared with other forms of sensors such as ranging sensors and photoelectric gates, it has lower cost and simpler structure.
