Demolding method of shell mold opening and demolding mechanism

Abstract

A shell mold opening and demolding mechanism is characterized by comprising a first slider, a second slider, a third slider, a fourth slider, an upper plate, a first oil cylinder and a second oil cylinder, wherein the upper end surface of the first slider has a first inclined block; the upper end surface of the third slider has a second inclined block; the second slider is provided with a first inclined hole, and the fourth slider is provided with a second inclined hole; the upper plate is provided with a first shovel, a second shovel, a first inclined guide column and a second inclined guide column downwardly. The present invention also discloses a demolding method. The first slider and the third slider are first loosened, and then the second slider and the fourth slider are loosened and hold the shell product, and finally the first slider and the third slider are completely disengaged synchronously. Since the product does not hold the first slider and the third slider tightly after loosening, it will naturally shrink when it encounters air, and will not be stretched due to the large holding force.

Description

Technical Field

[0001] The present invention relates to a demoulding structure of a shell mold, which can be applied to an air outlet of a vehicle air conditioner. The present invention also relates to a demoulding method. Background Art

[0002] Figure 1 This is an existing vehicle air-conditioning outlet 1a, which has a hollow inner cavity, including a front inner cavity 11a and a rear inner cavity 12a. At present, the shell product usually adopts four-sided slider demolding, including a first slider, a second slider, a third slider, and a fourth slider. The first slider and the third slider are arranged opposite to each other, and the second slider and the fourth slider are respectively arranged on the first slider and the third slider. The first slider, the second slider, the third slider, and the fourth slider are arranged in a ring in sequence; the front end of the first slider is formed with a first convex portion that is adapted to the front inner cavity of the shell, and the front end of the third slider is formed with a second convex portion that is adapted to the rear inner cavity of the shell. When demolding, the second slider and the fourth slider are disengaged at the same time, and then the first slider is disengaged, and finally the third slider is disengaged.

[0003] The above-mentioned demoulding has the following defects: the first slider and the third slider are demoulded separately, one after the other, resulting in a long contact time between the product and the air, that is, a long cooling time, and a large clamping force after shrinkage, resulting in a strain phenomenon; the strained area is more obvious on the inner wall in the middle of the shell product, and the product quality is reduced. Summary of the Invention

[0004] The first technical problem to be solved by the present invention is to provide a shell mold opening and demolding mechanism to avoid the problem of product quality being affected by the clamping force after shrinkage in response to the above-mentioned technical status quo.

[0005] The second technical problem to be solved by the present invention is to provide a demoulding method for a shell mold opening and demoulding mechanism in response to the above-mentioned technical status quo, which avoids the problem of product quality being affected by the clamping force after shrinkage.

[0006] The technical solution adopted by the present invention to solve the first technical problem mentioned above is: a shell mold opening and demolding mechanism, characterized by comprising a first slider, a second slider, a third slider, a fourth slider, an upper plate, a first oil cylinder and a second oil cylinder, wherein the first slider and the third slider are arranged opposite each other, the second slider and the fourth slider are respectively arranged on both sides of the first slider and the third slider, and the first slider, the second slider, the third slider and the fourth slider are arranged in a ring in sequence;

[0007] The front end of the first slider is formed with a first protrusion adapted to the front end inner cavity of the shell;

[0008] The front end of the third slider is formed with a second protrusion adapted to the rear end inner cavity of the housing;

[0009] The inner side surfaces of the second slider and the fourth slider are adapted to the outer side surface of the housing;

[0010] The upper end surface of the first slider has a first inclined block; the upper end surface of the third slider has a second inclined block;

[0011] The second slider is provided with a first oblique hole, and the fourth slider is provided with a second oblique hole;

[0012] The upper plate is provided with a first shovel, a second shovel, a first inclined guide column and a second inclined guide column downwardly;

[0013] The first shovel and the first inclined block are in contact and cooperate to drive the first sliding block to move backward;

[0014] The aforementioned second shovel is in contact with the second inclined block to drive the third slider to move backward;

[0015] The first inclined guide post contacts and cooperates with the first inclined hole to drive the second slider to move backward;

[0016] The second inclined guide post contacts and cooperates with the second inclined hole to drive the fourth slider to move backward;

[0017] The aforementioned first oil cylinder is drivingly connected to the first slider;

[0018] The aforementioned second oil cylinder is drivingly connected to the third sliding block.

[0019] The first slider is provided with a first adjustment component capable of adjusting the fit clearance, and the third slider is provided with a second adjustment component capable of adjusting the fit clearance. The first adjustment component is used to eliminate the fit clearance between the first shovel and the first inclined block to ensure close contact.

[0020] Preferably, the first slider has a mounting cavity, and the first adjustment component includes

[0021] a spring, disposed in the mounting cavity of the first slider;

[0022] a spring block, disposed at the outer end of the spring; and

[0023] The positioning component passes through the middle hole of the elastic block and the spring in sequence and is positioned in the installation cavity of the first sliding block.

[0024] In order to ensure that the first and third sliders are released first and the second and fourth sliders can control the shell product, the following improvements are made: there is a delay gap between the first inclined guide column and the first inclined hole and between the second inclined guide column and the second inclined hole.

[0025] Furthermore, the first oil cylinder is connected to the first slider via a connecting rod, and the connecting rod includes a horizontal portion connected to the first slider and a vertical portion connected to the first power output end.

[0026] The technical solution adopted by the present invention to solve the above second technical problem is: a demoulding method using a shell mold opening and demoulding mechanism, comprising the following steps:

[0027] When the mold is opened, the upper plate rises to drive the first and second shovels, thereby driving the first and third slides. The first adjustment component assists the first slide, and the second adjustment component assists the third slide to move backward for a distance synchronously, so that the first slide moves in the opposite direction to the third slide to loosen the shell first.

[0028] At the same time, the first inclined guide column drives the second and fourth slide blocks to demould after a delay due to the delay gap.

[0029] Then the first oil cylinder and the second oil cylinder simultaneously drive the first slide block and the third slide block to demould.

[0030] Compared with the prior art, the advantages of the present invention are that: the first slider and the third slider are loosened first, and then the second slider and the fourth slider are loosened and hold the shell product, and finally the first slider and the third slider are completely disengaged synchronously. Since the product does not hold the first slider and the third slider tightly after loosening, it shrinks naturally when encountering air, and will not cause the product to be stretched due to the large holding force. Subsequently, the first oil cylinder and the second oil cylinder also act synchronously, and the demoulding time is greatly shortened, which is conducive to stabilizing product quality.
