Description

Technical Field

[0001] The utility model relates to an injection mold, in particular to a front mold spring plate buckle machine control structure. Background Art

[0002] When injection molding some special plastic products, it is necessary to control the mold opening sequence. At the beginning of mold opening, it is necessary to control template 1 and template 2 to be locked and not move, and the hot runner plate is separated from template 1 first. After the hot runner plate is opened to a certain distance, template 1 and template 2 can be opened; when closing the mold, template 1 and template 2 must be closed in place first, and then the hot runner plate and template 1 are closed together.

[0003] Therefore, the existing practice is to set a spring and a limit screw between the hot runner plate and template one. When the mold is opened, the elastic force of the spring brings template one and template two together and the hot runner plate is separated from template one. The limit screw has a certain moving distance and moves with the hot runner plate; when the limit screw moves to a position where it is stuck with template one, template one will move together with the hot runner plate and then separate from template two through the pulling of the limit screw, thereby achieving the mold opening requirement. The mold closing process is the opposite of the above process.

[0004] The above structure utilizes the elasticity of the spring to push the template and the hot runner plate to ensure the order of mold closing and mold opening. Because it is often compressed repeatedly under high temperature and long-term high pressure, the spring is prone to failure after a period of use and has a relatively short life. Therefore, the applicant has designed a front mold spring plate buckle machine control structure to solve the above problem. Utility Model Content

[0032] Reference Figures 1 to 6 The utility model discloses a front mold spring plate locking machine control structure, including a hot runner plate 1, a template 1 2 and a template 2 3 arranged in sequence, including a control rod 4 fixed to the hot runner plate 1, a locking machine box 5 fixed to the template 2 3, a slider 1 6 and a slider 2 7 arranged in the template 1 2, the slider 1 6 and the slider 2 7 are both able to maintain a state where one end extends out of the template 1 2 through the action of an elastic member 8 and a limiting member 9, the control rod 4 is provided with a rod limiting structure that can be engaged with the slider 1 6 during mold closing so that the hot runner plate 1 cannot be closed with the template 1 2, the locking machine box 5 is provided with a box guiding structure so that the slider 2 7 and the slider 1 6 can be pressed into the template 1 2 in sequence during mold closing, the locking machine box 5 is provided with a box limiting structure that can be engaged with the slider 2 7 during mold opening so that the template 1 2 and the template 2 3 cannot be separated, and the control rod 4 is provided with a rod guiding structure so that the slider 2 7 can be pressed into the template 1 2 during mold opening.

[0033] The principle of the above technical solution to realize mold opening and mold closing is as follows: when in the state of fully open mold, the hot runner plate 1, template 1 2 and template 2 3 are all separated, and the rod guide structure of the control rod 4 contacts and squeezes the slider 2 7; then the mold closing begins, the hot runner plate 1 and template 1 2 begin to move in the direction of template 2 3, at this time the control rod 4 also moves, the rod guide structure moves to the position below the slider 2 7, and the slider 2 7 pops out, but at this time the rod limiting structure and the slider 1 6 are against each other, resulting in the hot runner plate 1 and template 1 2 cannot be closed and maintain a certain distance, the hot runner plate 1 and template 1 2 continue to move together, and the machine is locked. The box 5 can sequentially press the slider 2 7 and the slider 1 6 into the template 1 2 through the box guide structure. Therefore, during this process, the slider 2 7 and the slider 1 6 will not restrict the buckle box 5 until the template 1 2 and the template 2 3 are in contact and closed. At this time, the box guide structure is just in contact with the slider 1 6, and the slider 1 6 is in a state of being pressed into the template 1 2, while the slider 2 7 is in an extended state. At this time, the template 1 2 cannot move, but the hot runner plate 1 continues to move, and because the slider 1 6 has been pressed into the template 1 2 by the box guide structure, the control rod 4 can also continue to move with the hot runner plate 1 at the same time until the hot runner plate 1 and the template 1 2 are in contact and closed.

[0034] When in the state of complete mold closing, the hot runner plate 1, template 1 2 and template 2 3 are all closed, and the hot runner plate 1 and template 1 2 begin to move away from template 2 3. At this time, the locking box 5 is locked with the slider 2 7 through the box limiting structure so that template 1 2 and template 2 3 cannot be separated, so the hot runner plate 1 and the control rod 4 move until the hot runner plate 1 and template 1 2 are separated to a predetermined distance. At this time, the rod guide structure also moves with the control rod 4 to a position at the same height as the slider 2 7, and at the same time squeezes the slider 2 7 to press it into the template 1 2. At this time, the slider 2 7 will no longer interact with the box limiting structure, so the template 1 2 begins to move with the hot runner plate 1 until the mold is fully opened.

[0035] As a preferred structure of the present application, a box slot 10 is provided in the latch box 5, and the control rod 4 can slide in the box slot 10. This design has a compact structure and saves space.

[0036] As shown in the figure, the box guiding structure includes a box extrusion end 11 arranged at the end of the latch box 5 and a box guiding inclined surface 12 arranged on the box extrusion end 11. The box extrusion end 11 is a convex block protruding from the side of the latch box 5 close to the template 2 3, and the box guiding inclined surface 12 is an inclined surface on the convex block. Therefore, through the guidance of the inclined surface, the convex block can gradually squeeze the slider 1 6 or the slider 2 7 back into the template 1 2; the rod guiding structure includes a rod extrusion end 13 arranged at the end of the control rod 4 and a rod guiding inclined surface 14 arranged on the rod extrusion end 13. The rod extrusion end 13 is a convex block protruding from the side of the control rod 4 close to the template 1 2, and the rod guiding inclined surface 14 is an inclined surface on the convex block. The principle of the rod extrusion end 13 is the same as that of the box extrusion end 11, so it is not repeated.

[0037] As shown in the figure, the rod limiting structure is a control rod step 15 arranged on the control rod 4. The control rod 4 includes a wider upper section 16 and a narrower lower section 17. Therefore, the part of the upper section 16 that is higher than the lower section 17 forms the control rod step 15, so that it can be clamped with the slider 6, and the rod extrusion end 13 is a convex block protruding from the lower section 17 of the control rod 4.

[0038] The box limiting structure is a locking box step 18 arranged on the locking box 5, and the locking box step 18 is formed by a raised part on the locking box 5, so that it can be locked with the slider 2 7. In order to facilitate manufacturing, the locking box 5 is divided into two parts and fixed together by screws.

[0039] As shown in the figure, the template 1 2 is provided with a sliding hole 19, the slider 1 6 and the slider 2 7 are located in the corresponding sliding hole 19, and the elastic member 8 is a spring located in the sliding hole 19, the slider 1 6 and the slider 2 7 are against the ends of the corresponding springs, and the other end of the spring is against the bottom of the sliding hole 19, and the sliding hole 19 is provided with a limiting convex ring (not shown in the figure), and the limiting member 9 is a screw rod, which is located in the sliding hole 19 and passes through the limiting convex ring and is threadedly connected to the bottom of the sliding hole 19, and the nut of the screw rod can be against the limiting convex ring. Through the above structure, the slider 1 6 and the slider 2 7 can not only return to the sliding hole 19 when compressed, but also extend out of the sliding hole 19 through the spring, and will not fall out of the sliding hole 19 because the limiting convex ring is locked with the nut.

[0040] The template 1-2 is provided with a limiting screw (not shown in the figure) and a limiting hole (not shown in the figure), and a through hole is provided at the bottom of the limiting hole. The top cap of the limiting screw is located in the limiting hole and can be abutted against the bottom of the limiting hole, and the limiting screw passes through the through hole to be connected to the hot runner plate 1. The above structure can limit the separation distance between the hot runner plate 1 and the template 1-2.

[0041] The above is a detailed introduction to a front mold spring plate buckle machine control structure provided by an embodiment of the utility model. Specific examples are used in this article to illustrate the principle and implementation method of the utility model. The description of the above embodiments is only used to help understand the method and core idea of ​​the utility model; at the same time, for general technical personnel in this field, according to the idea of ​​the utility model, there will be changes in the specific implementation method and application scope. In summary, the content of this specification should not be understood as a limitation on the utility model.
