Description

Technical Field

[0001] The utility model belongs to the technical field of injection molds, in particular to a front shell mold of an air conditioner. Background Art

[0002] like Figure 3-Figure 5 As shown in the figure, since the side of the front shell of the air conditioner has an undercut 4, the existing mold adopts a cylinder-driven oblique core-pulling structure for demoulding. The existing mold has a demoulding sequence, which is easy to cause collision and die pressing. When the injection molding pressure increases, the cylinder clamping force is insufficient, and the product is prone to breakage and flash. In addition, during injection molding production, the slider often sticks, the product qualification rate is low, and the production cycle is too long. Utility Model Content

[0003] The purpose of the utility model is to provide a front housing mold of an air conditioner in order to overcome the defects of the prior art.

[0004] The purpose of the utility model can be achieved through the following technical solutions:

[0005] The utility model provides a front housing mold of an air conditioner, comprising:

[0006] Upper template;

[0007] a lower mold plate, wherein a mold cavity is formed between the upper mold plate and the lower mold plate; and

[0008] A demoulding slider assembly, comprising an inclined guide column fixedly connected to the upper template, a slider unit slidably connected to the lower template, and a third slider movably connected to the slider unit;

[0009] When the upper and lower mold plates are demoulded, the slider unit is driven by the inclined guide column to move away from the mold cavity, thereby pushing the third slider to slide obliquely downward and disengage from the barb on the lower surface of the front shell of the air conditioner.

[0010] Furthermore, one end of the third sliding block is provided with a slot matching with the undercut of the front housing of the air conditioner.

[0011] Furthermore, the slider unit comprises:

[0012] First slider;

[0013] a bundle block fixedly connected to the first sliding block; and

[0014] A second sliding block, which has a trapezoidal cross section and is fixedly connected to the bundle block;

[0015] A strip groove is arranged on one side of the second sliding block close to the third sliding block, and the third sliding block slides in the strip groove.

[0016] Furthermore, limiting members for preventing the third sliding block from escaping from the strip groove are arranged at both ends of the strip groove.

[0017] Furthermore, the first slider includes:

[0018] A first portion, one end of which abuts against the mold cavity; and

[0019] A second part, which is vertically connected to the first part, and the second part has an oblique slot for accommodating the oblique guide column;

[0020] One end of the second portion is fixedly connected to the bundle block, and when the upper mold plate is demoulded from the lower mold plate, the inclined guide column is separated from the inclined slot and drives the first sliding block to separate from the mold cavity.

[0021] Furthermore, the first part and the second part are integrally formed.

[0022] Furthermore, a fixing piece fixedly connected to the inclined guide column is arranged in the upper template.

[0023] Furthermore, the bundle block is fixedly connected to the first sliding block by bolts.

[0024] Furthermore, the bundle block is fixedly connected to the second sliding block by bolts.

[0025] Furthermore, it also includes an ejector assembly, which is arranged on the injection molding machine and is used to control the clamping and demolding of the upper mold plate and the lower mold plate.

[0026] The working principle of the utility model is:

[0027] The injection molding machine demoulds, and the two oil cylinders of the ejector assembly drive the two ejector plates to separate the upper template 1 and the lower template respectively. Since the inclined guide column is fixed on the first template, and because the inclined guide column moves vertically upward, and because the inclined notch provided on the first slider matches the inclined guide column, when the inclined guide column moves vertically upward and disengages from the inclined notch, the first slider has the force to move horizontally to the right, so the inclined guide column drives the first slider to move to the right, and the first slider moves to the right, driving the bundle block to move to the right and the second slider to move to the right. At this time, the first slider is away from the mold cavity. One end of the third slider slides in the strip groove of the second slider, so the second slider moves to the right and drives the third slider to move obliquely downward in the strip groove. At this time, the card slot provided on the third slider is separated from the underhook of the front shell of the air conditioner, and the manipulator takes out the front shell of the air conditioner.

[0028] When closing the mold, the injection molding machine closes the mold, the two cylinders of the ejector assembly drive the two ejector plates to respectively drive the upper template and the lower template to merge, the inclined guide column moves obliquely downward and enters the oblique slot on the first slider, the inclined guide column moves obliquely downward and drives the first slider to move to the left, the first slider moves to the left and drives the bundle block to move to the left and drives the second slider to move to the left, the second slider moves to the left and drives the third slider to slide obliquely downward in the strip groove and return to the initial position, completing a production cycle.

[0029] Compared with the prior art, the utility model has the following beneficial effects:

[0030] (1) The utility model utilizes the opening and closing of the upper mold plate and the lower mold plate to greatly shorten the molding cycle.

[0031] (2) The upper mold plate, lower mold plate structure and the connection method with the demoulding slider assembly of the utility model are safe and reliable and will not collide with the die.

[0032] (3) The demoulding slider assembly of the utility model is not prone to generation of breakage and flash during injection molding.

[0033] (4) The utility model saves mold costs, increases output, and reduces production costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0068] Example 1

[0069] In order to avoid collision with the die during demoulding, save costs, and prevent generation of breakage and flash during injection molding, this embodiment provides a front housing mold for an air conditioner, and its structure is shown in FIG. Figure 1 and Figure 2 As shown, including:

[0070] Upper template 1;
