Description

Technical Field

[0001] This utility model belongs to the field of hot cutting mold technology, and in particular relates to a phased self-locking gainer. Background Technology

[0002] like Figure 5 As shown, in common die-casting or injection molds, the traditional technique for removing runners or slag pockets from molded products 104 often involves manual or mechanical cutting outside the mold. With the maturity of in-mold thermal cutting technology in recent years, this technology has gradually been applied, enabling the automatic removal of runners or slag pockets within the mold.

[0003] However, this technology currently suffers from several insurmountable flaws in the industry: the hot-cutting blade fails to close completely or retracts after reaching its designated position, resulting in poor in-mold cutting and large burrs or even failure to cut the gate. Particularly for products with long injection molding holding times, the prolonged stop time at the gate causes gradual solidification, increasing the viscosity and density of the material. This makes it difficult for the hot-cutting blade to compress the space, requiring significant power for extrusion. This high power demand necessitates the use of extremely high-pressure hydraulic oil in the pump, and the hydraulic cylinders and circuits must withstand extremely high pressure, leading to potential damage or requiring the design of ultra-high pressure-bearing equipment or devices. Simultaneously, the hot-cutting blade, subjected to extremely high stress, is prone to deformation or breakage, affecting its service life.

[0004] Based on this, this application proposes a phase-locked gainer. Utility Model Content

[0005] The purpose of this utility model embodiment is to provide a phased self-locking gainer, which aims to solve the technical problems existing in the prior art mentioned in the background art.

[0006] This utility model embodiment is implemented as follows: a phase-locking gainer includes:

[0007] Gain input section;

[0008] The gain output section engages with the gain input section via a wedge, such that when the gain input section slides, the gain output section can rise and / or fall relative to the gain input section.

[0009] The number of the wedges is at least one, and the number of the gain outputs is also at least one, and each gain output is engaged with the gain input through at least one wedge;

[0010] When the number of the wedges is one, the gain output section can rise or fall relative to the gain input section 2;

[0011] When the number of the wedges is two or more, the gain output can rise and / or fall relative to the gain input.

[0012] Preferably, it also includes a telescopic component for driving the gain input section to move linearly.

[0013] More preferably, the number of wedges is at least one, and correspondingly, the number of gain outputs is also at least one, and each gain output cooperates with a gain input through at least one wedge;

[0014] When the number of the wedges is one, the gain output section can rise or fall relative to the gain input section;

[0015] When the number of the wedges is two or more, the gain output can rise and / or fall relative to the gain input.

[0016] More preferably, the number of gain input sections is at least one. When there are two or more gain input sections, the two or more gain input sections can be driven by at least one telescopic member to achieve linear movement of the gain input sections.

[0017] More preferably, the wedge has a T-shaped cross-section.

[0018] The beneficial effects of this utility model embodiment are as follows: by setting a wedge, based on the principle of force decomposition on an inclined plane, the gain output part has the effect of output force gain and self-locking, so as to realize the synchronous equidistant opposite movement of the gain output parts on both sides, thereby meeting the movement requirements of the cutter and the pressure relief rod.

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] It is understood that the terms “first,” “second,” etc., used in this application may be used herein to describe various elements, but unless otherwise stated, these elements are not limited by these terms. These terms are used only to distinguish one element from another.

[0027] like Figure 1 As shown, in one embodiment, a phase-locking gainer is proposed, comprising:

[0028] Gain input section 2;

[0029] The gain output section 3 is engaged with the gain input section 2 via a wedge 4, so that when the gain input section 2 slides, the gain output section 3 can rise and / or fall relative to the gain input section 2.

[0030] Before describing the specific working principle of this embodiment, we will first illustrate the specific application scenario of this embodiment, such as... Figure 5 As shown, in common die-casting or injection molds, the traditional technique for removing runners or slag pockets from molded products 104 often involves manual or mechanical cutting outside the mold. With the maturity of in-mold thermal cutting technology in recent years, this technology has gradually been applied, enabling the automatic removal of runners or slag pockets within the mold.

[0031] The main structure of die casting or injection molds is as follows: Figure 5 As shown, the mold includes a fixed mold plate 101, a fixed mold plate 102, a fixed mold core 103, a cutter 105, a moving mold plate 106, a moving mold plate 107, a runner 108, a pressure relief rod 109, a moving mold core 110, a square iron 111, an ejector base plate 112, and an ejector panel 113. In practical applications, these components need to provide synchronous, equidistant, opposing power output, self-locking anti-backwardness, and power output gain amplification for the cutter 105 and pressure relief rod 409 of the mold.

[0032] In this embodiment, by setting a wedge 4, the cross-section of the wedge 4 can be a T-shaped structure. According to the principle of force decomposition on an inclined plane, the gain output section has the effects of output force gain and self-locking.

[0033] like Figure 1 As shown, in a preferred embodiment of the present invention, a telescopic member 1 is also included for driving the gain input section 2 to move in a straight line.

[0034] In one embodiment, the telescopic member 1 can be a hydraulic cylinder, a pneumatic cylinder, or a linear servo mechanism, etc., as long as it can drive the gain input unit 2 to move in a straight line. This embodiment does not impose any specific limitations.

[0035] like Figure 1 As shown, in a preferred embodiment of the present invention, the number of the wedges 4 is at least one, and correspondingly, the number of the gain output section 3 is also at least one, and each gain output section 3 cooperates with the gain input section 2 through at least one wedge 4;

[0036] When the number of the wedges 4 is one, the gain output section 3 can rise or fall relative to the gain input section 2;

[0037] When the number of the wedges 4 is two or more, the gain output section 3 can rise and / or fall relative to the gain input section 2.

[0038] In this embodiment, when the number of the wedges 4 is one, the number of the gain output unit 3 and the gain input unit 2 needs to be set to two sets to drive the movement of the cutter 105 and the pressure relief rod 409 respectively.

[0039] When the number of the wedges 4 is two or more, the gain output section 3 can rise and / or fall relative to the gain input section 2.

[0040] In one embodiment, there can be two wedges 4, which are located on both sides of the gain input section 2. The two wedges 4 are in opposite directions. In this way, two gain output sections 3 can be connected to one gain input section 2. At this time, the two gain output sections 3 can move in opposite directions, thereby realizing the reverse movement of the cutter 105 and the pressure relief rod 409.

[0041] like Figure 2 , Figure 3 and Figure 4 As shown, in another preferred embodiment of the present invention, the number of gain input sections 2 is at least one. When there are two or more gain input sections 2, the two or more gain input sections 2 can be driven by at least one telescopic member 1 to achieve linear movement of the gain input sections 2.

[0042] In one embodiment, one telescopic member 1 can drive one gain input unit 2, two telescopic members 1 can drive two gain input units 2 respectively, or three telescopic members 1 can drive two gain input units 2. The specific choice can be made according to actual needs, and this embodiment does not impose any specific limitations.

[0043] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0044] 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 this 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.

[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
