Description

Technical Field

[0001] The present invention relates to the technical field of molds, and in particular to a lateral core pulling mechanism and a mold. Background Art

[0002] In the prior art, the demoulding direction of the product and the demoulding direction of the structure integrally formed with it are sometimes inconsistent, such as Figures 1 to 4 As shown, the demolding directions of the product 400 and the integrally formed snap-in screw column 410 are inconsistent. The direction indicated by arrow X is the demolding direction of the product 400, and the direction indicated by arrow Y is the demolding direction of the snap-in screw column 410. In the prior art, a movable mold spring is usually added to the mold to drive an oblique withdrawal mechanism to complete the demolding of the snap-in screw column 410. However, the mold cost of adding a movable mold spring is relatively high. Summary of the Invention

[0003] The first purpose of the present invention is to provide a lateral core pulling mechanism to solve the technical problem in the prior art that when the demoulding direction of the product is inconsistent with the structure above it, the demoulding problem of the structure is solved by adding a dynamic mold spring plate to the mold, and the cost of the mold is relatively high.

[0004] The lateral core pulling mechanism provided by the present invention includes a slider, an oblique pulling mop, an oblique pulling insert and an inserting needle. The oblique pulling mop is fixedly installed on the slider, the oblique pulling insert is slidably connected to the oblique pulling mop, and the inserting needle is fixedly installed on the oblique pulling insert; when the slider drives the oblique pulling mop to move, the oblique pulling insert slides relative to the oblique pulling mop and drives the inserting needle to complete the core pulling.

[0005] The lateral core pulling mechanism provided by the present invention can produce the following beneficial effects:

[0006] The lateral core-pulling mechanism provided by the present invention utilizes a slider and an oblique pull handle to provide power, replacing a dynamic mold spring plate. The slider and oblique pull handle are linked to the oblique insert and insert pin, achieving core-pulling motion for the insert pin. Compared to a dynamic mold spring plate, the lateral core-pulling mechanism provided by the present invention has a simpler structure and simpler motion, resulting in lower mold production costs. Furthermore, due to its simple motion, assembly is also simple and efficient.

[0007] Furthermore, one of the oblique-pull mop and the oblique-pull insert is provided with a card slot, and the other is provided with a card head, and the card head matches the card slot and is slidably engaged.

[0008] In this technical solution, through the cooperation between the clamping head and the clamping slot, a sliding connection between the oblique-pull mop and the oblique-pull insert is achieved, and a reliable connection between the two is achieved.

[0009] Furthermore, the oblique-pull mop is provided with a T-shaped slot, and the oblique-pull insert is provided with a T-shaped clamping head, and the T-shaped clamping head matches the T-shaped slot and is slidably engaged.

[0010] In this technical solution, the T-shaped slot is matched with the T-shaped clamp head, which has a simple structure and is easy to process. Moreover, compared with the spherical clamp head and the matching slot, the position of the T-shaped clamp head in the T-shaped slot is stable, thereby ensuring the smooth movement of the obliquely withdrawn insert and the insert needle.

[0011] Furthermore, the lateral core pulling mechanism also includes an elastic member, which is arranged in the slider. In the mold closing state and the mold opening process, the elastic member applies a force to the slider, and the direction of the force is the sliding direction of the slider relative to the movable mold during the mold opening process.

[0012] In this technical solution, whether in the mold closing state or in the mold opening process, the elastic part can press the slider against the slider's mating part, so that the slider and its mating part are in close contact, thereby effectively avoiding the vibration of the slider, and then effectively avoiding the vibration of the oblique pull mop, oblique pull insert and insert needle, which is ultimately beneficial to improving the molding accuracy of the product.

[0013] Furthermore, the lateral core pulling mechanism also includes a guide assembly, which includes an inclined guide column, a fixed seat and a fixing piece. The fixed seat can be fixedly installed on the fixed mold through the fixing piece, and the inclined guide column is fixedly installed on the fixed seat; the slider is slidably connected to the inclined guide column, and during the mold opening process, the slider slides along the inclined guide column.

[0014] In this technical solution, the inclined guide pin guides the slider. When the movable mold moves downward to open the mold, the movable mold drives the slider downward. Under the action of the inclined guide pin, the slider not only moves downward, but also moves to one side, thereby driving the inlay pin to complete the core pulling movement with the movement direction forming an angle with the movement direction of the movable mold.

[0015] Furthermore, the lateral core-pulling mechanism further includes a first pressure strip, which can be fixedly connected to the fixed mold, and the first pressure strip is used to contact the upward surface of the obliquely pulled mop.

[0016] In this technical solution, the first pressure strip is in contact with the oblique mop, which effectively avoids wear between the oblique mop and the fixed mold, and protects both the oblique mop and the fixed mold; in addition, compared with the fixed mold, the first pressure strip is easy to disassemble and replace, and the cost is low.

[0017] Furthermore, the lateral core-pulling mechanism further includes a second pressure strip, which can be fixedly connected to the fixed mold, and the downward surface of the obliquely pulled mop is overlapped with the second pressure strip.

[0018] In this technical solution, the second pressure strip supports the oblique pull-out mop. At the same time, the second pressure strip can effectively prevent wear between the oblique pull-out mop and the movable mold, and protects both the oblique pull-out mop and the movable mold. Compared with the movable mold, the second pressure strip is easy to disassemble and replace, and the cost is low.

[0019] Furthermore, the lateral core-pulling mechanism further includes a third pressure strip, which can be fixedly connected to the movable mold and is used to limit the movement of the slider toward the fixed mold.

[0020] In this technical solution, the third pressure strip serves to limit the slider, thereby improving the movement accuracy of the slider, thereby improving the movement accuracy of the inlay pin and ensuring the molding accuracy of the product.

[0021] The second purpose of the present invention is to provide a mold to solve the technical problem in the prior art that when the demoulding direction of the product and the structure thereon are inconsistent, the demoulding problem of the structure is solved by adding a dynamic mold spring plate to the mold, and the cost of the mold is relatively high.

[0022] The mold provided by the present invention comprises a movable mold, a fixed mold, and the aforementioned lateral core-pulling mechanism. The guide assembly of the lateral core-pulling mechanism is fixedly mounted on the fixed mold, while the other components of the lateral core-pulling mechanism are mounted on the movable mold. This mold has all the advantages of the aforementioned lateral core-pulling mechanism, so they will not be described in detail here.

[0023] Furthermore, the movable mold includes a movable platen, and the movable platen is provided with a limiting portion, and the limiting portion is used to limit the sliding of the slider along the movable platen. When the slider abuts against the limiting portion, the inserting needle completes the core pulling. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] In order to make the above-mentioned objects, features and advantages of the present invention more clearly understood, the following detailed description of the specific embodiments of the present invention is given in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0042] This embodiment provides a lateral core pulling mechanism, such as Figures 5 to 9As shown, it includes a slider 110, an oblique pull-out mop 120, an oblique pull-out insert 130 and an insert pin 140. The oblique pull-out mop 120 is fixedly installed on the slider 110, the oblique pull-out insert 130 is slidably connected to the oblique pull-out mop 120, and the insert pin 140 is fixedly installed on the oblique pull-out insert 130; when the slider 110 drives the oblique pull-out mop 120 to move, the oblique pull-out insert 130 slides relative to the oblique pull-out mop 120 and drives the insert pin 140 to complete core pulling.

[0043] The lateral core-pulling mechanism provided in this embodiment uses a slider 110 and an oblique puller 120 to provide power instead of a dynamic mold spring. The slider 110 and oblique puller 120 are linked to the oblique insert 130 and insert pin 140 to achieve core-pulling motion of the insert pin 140. Compared to a dynamic mold spring, the lateral core-pulling mechanism provided in this embodiment has a simpler structure and simpler motion, resulting in lower mold production costs. Furthermore, due to its simple motion, assembly is also simple and efficient.

[0044] Specifically, in this embodiment, the oblique pull-out mop 120 is provided with a slot, and the oblique pull-out insert 130 is provided with a head, which matches the slot and slides into engagement. The cooperation between the head and the slot enables both a sliding connection between the oblique pull-out mop 120 and the oblique pull-out insert 130 and a reliable connection between the two.

[0045] It should be noted that in other embodiments of the present application, the card slot is not limited to being set on the oblique pull-out mop 120, and the card head is not limited to being set on the oblique pull-out insert 130. Instead, the card slot can also be set on the oblique pull-out insert 130, and correspondingly, the card head is set on the oblique pull-out mop 120.

[0046] More specifically, in this embodiment, the angled-pull mop handle 120 is provided with a T-shaped slot, and the angled-pull insert 130 is provided with a T-shaped head. The T-shaped head matches the T-shaped slot and slides into engagement. The T-shaped slot and the T-shaped head are simple in structure and easy to manufacture. Furthermore, compared to a spherical head and its matching slot, the T-shaped head maintains a stable position within the T-shaped slot, thereby ensuring smooth movement of the angled-pull insert 130 and the insert pin 140.

[0047] Specifically, in this embodiment, Figure 8As shown, the lateral core pulling mechanism 100 further includes an elastic member 150, which is disposed within the slider 110. In the mold closing state and the mold opening process, the elastic member 150 applies a force to the slider 110, and the direction of the force is the sliding direction of the slider 110 relative to the movable mold during the mold opening process. Under this arrangement, whether in the mold closing state or the mold opening process, the elastic member 150 can press the slider 110 against the matching part of the slider 110, thereby ensuring close contact between the slider 110 and its matching part, thereby effectively preventing vibration of the slider 110, and further effectively preventing vibration of the oblique pull mop 120, the oblique pull insert 130, and the insert pin 140, ultimately contributing to improved product molding accuracy.

[0048] More specifically, in this embodiment, the elastic member 150 is a compression spring. However, in other embodiments of the present application, the elastic member 150 is not limited to a compression spring and may also be a rubber member, etc. In other words, as long as it can apply a compressive force to the slider 110, the present application does not impose any restrictions on the specific structure of the elastic member 150.

[0049] Specifically, in this embodiment, Figures 7 to 9 As shown, the lateral core-pulling mechanism further includes a guide assembly 160, which includes an inclined guide post 161, a fixed seat 162, and a fixing member 163. The fixing seat 162 can be fixedly mounted on the fixed mold via the fixing member 163, and the inclined guide post 161 is fixedly mounted on the fixed seat 162. The slider 110 is slidably plugged into the inclined guide post 161. During the mold opening process, the slider 110 slides along the inclined guide post 161. The inclined guide post 161 guides the slider 110. When the movable mold moves downward to open the mold, the movable mold drives the slider 110 downward. Under the action of the inclined guide post 161, the slider 110 not only moves downward but also moves to one side, thereby driving the inlay pin 140 to complete the core-pulling movement with the movement direction forming an angle with the movement direction of the movable mold.

[0050] Specifically, in this embodiment, Figure 8 As shown, the side core pulling mechanism also includes a first pressure strip 170, which can be fixedly connected to the fixed mold. The first pressure strip 170 is used to contact the upward surface of the angled pull mop 120. In this arrangement, the first pressure strip 170 contacts the angled pull mop 120, effectively preventing wear between the angled pull mop 120 and the fixed mold, and protecting both the angled pull mop 120 and the fixed mold. In addition, compared to the fixed mold, the first pressure strip 170 is easier to remove and replace, and the cost is also lower.

[0051] Specifically, in this embodiment, continue as Figure 8As shown, the lateral core-pulling mechanism further includes a second pressure strip 180, which can be fixedly connected to the fixed mold, and the downward-facing surface of the oblique-pulling mop 120 overlaps the second pressure strip 180. In this arrangement, the second pressure strip 180 supports the oblique-pulling mop 120 and effectively prevents wear between the oblique-pulling mop 120 and the movable mold, thus protecting both the oblique-pulling mop 120 and the movable mold. Furthermore, compared to the movable mold, the second pressure strip 180 is easy to remove and replace at a low cost.

[0052] Specifically, in this embodiment, Figure 11 As shown, the lateral core-pulling mechanism also includes a third pressure strip 191, which is fixedly connected to the movable mold and is used to limit the movement of the slider 110 toward the fixed mold. In this arrangement, the third pressure strip 191 acts as a limiter for the slider 110, improving the movement accuracy of the slider 110 and, in turn, the movement accuracy of the insert pin 140, thereby ensuring the molding accuracy of the product.

[0053] This embodiment further provides a mold comprising a movable mold, a fixed mold, and the aforementioned lateral core pulling mechanism. The guide assembly 160 of the lateral core pulling mechanism is fixedly mounted on the fixed mold, while the other components of the lateral core pulling mechanism are mounted on the movable mold. This mold possesses all the advantages of the aforementioned lateral core pulling mechanism, and therefore will not be further described here.

[0054] Specifically, in this embodiment, the movable mold includes a movable template 210, and the movable template 210 is provided with a limiting portion, which is used to limit the sliding of the slider 210 along the movable template 210. When the slider 110 abuts against the limiting portion, the inserting pin 140 completes the core pulling.

[0055] Specifically, in this embodiment, the fixed mold includes a fixed mold plate 310 and a fixed mold core 320 , and the movable mold also includes a movable mold core 220 .

[0056] The mold provided in this embodiment is as follows Figure 7 、 Figure 9 and Figure 10 As shown, in the mold closing state, the slider 110 is assembled on the movable mold plate 210 through the third pressure strip 191, the inclined guide column 161 is assembled in the fixed seat 162, the fixed seat 162 is fixed to the fixed mold plate 310 through the second fixing member 163, and the compression spring is assembled in the slider 110 to assist the slider 110 in completing the core pulling action when the mold is opened; the oblique pulling mop 120 is fixed to the slider 110 through the first fixing member 115, and the oblique pulling insert 130 is installed in the T-shaped slot of the oblique pulling mop 120, the first pressure strip 170 is fixed on the movable mold core 220, and has an anti-wear effect on the oblique pulling insert 120, the second pressure strip 180 is fixed on the movable mold core 220, and the movable mold core 220 is fixed to the 210 movable mold plate through the third fixing member 215.

[0057] The mold provided in this embodiment is as follows Figure 8 As shown, when the mold is opened, the movable template 210 moves downward and is driven to move simultaneously in the same direction by the third fixing member 215. At the same time, the inclined guide column 161 moves the slider 110 to drive the inclined pull-out mop 20 to move along the horizontal plane of the movable template 210 to perform lateral core pulling movement. The inclined pull-out mop 120 drives the inclined pull-out insert 130 and the insert needle 140 to move simultaneously. The core pulling action is completed by the slider 110 assisted by the compression spring. The core pulling movement stops when the slider 110 touches the limit part of the movable template 210.

[0058] It should be noted that, in this embodiment, the structure integrally formed with the product 400 may be a snap screw column 410, but the lateral core pulling mechanism and mold provided in this embodiment are not limited to the molded snap screw column 410 and the corresponding product 400, but can also be applied to other products and situations where the demolding direction of the structure integrally formed therewith is inconsistent.
