Description

Technical Field

[0001] The utility model relates to the technical field of forming molds for washing machine parts, and more specifically to a forming mold for a dehydrating barrel of a washing machine. Background Art

[0002] The outer drum of a drum washing machine is an important part inside the washing machine, usually installed outside the inner drum of the washing machine. The main function of the outer drum is to surround the inner drum and keep a certain distance from it, to protect the inner drum and prevent friction between the inner drum and the outer wall, and also to reduce noise and vibration when the washing machine is running.

[0003] Combination Figure 1-2 As shown, in the prior art, the same side wall of the outer drum is designed with a first joint and a second joint, which are usually used to connect other parts inside the washing machine, such as a heating element, a water pump, etc. The first joint and the second joint are oriented in different directions. Due to its special structure, demoulding becomes more difficult, and the outer drum plastic part cannot be demoulded by a simple one-way operation. Summary of the invention

[0009] According to an embodiment of the utility model, the movable mold is provided with a second stopper for limiting the travel of the first slider.

[0010] According to an embodiment of the utility model, a spring is provided between the first slider and the first tunnel slider; the spring is used to provide a reverse force to ensure that the first slider remains stable at a certain position.

[0038] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention. Example

[0039] Combination Figure 1-2 As shown, the plastic part in the figure is the outer drum 1 of the dehydration barrel of the drum washing machine, and the same side wall of the outer drum 1 is designed with a first joint 11 and a second joint 12, wherein the first joint 11 and the second joint 12 are both roughly tangent to the inner wall of the outer drum 1, and the first joint 11 and the second joint 12 are oriented in different directions.

[0040] like Figure 3-14 As shown, in this embodiment, a forming mold for a washing machine dehydration barrel is disclosed, including a first lateral core-pulling mechanism 2 and a second lateral core-pulling mechanism 3 installed on a movable mold, wherein the first lateral core-pulling mechanism 2 includes a first slider 21 and a first tunnel slider 22, and the second lateral core-pulling mechanism 3 includes a second slider 31 and a second tunnel slider 32. The first slider 21 is slidably installed on the second slider 31, and the combination of the first slider 21 and the first tunnel slider 22 is used to form a first joint 11 on an outer cylinder 1, and the combination of the second slider 31 and the second tunnel slider 32 is used to form a second joint 12 on the outer cylinder 1.

[0041] Furthermore, in this embodiment, the first lateral core pulling mechanism 2 and the second lateral core pulling mechanism 3 form an integral secondary slider, that is, the first lateral core pulling mechanism 2 serves as a small slider in the secondary slider, and the second lateral core pulling mechanism 3 serves as a large slider in the secondary slider. First, the first lateral core pulling mechanism 2 is actuated to complete the demoulding of the first joint 11, and then the second lateral core pulling mechanism 3 is actuated to complete the demoulding of the second joint 12.

[0042] Specifically, combined Figure 3-9 As shown, the first lateral core pulling mechanism 2 also includes an inclined guide column 25 installed on the fixed mold, the first slider 21 and the first tunnel slider 22 are both provided with an inclined guide hole 22a adapted to the inclined guide column 25, the first tunnel slider 22 is slidably installed on the upper part of the first slider 21, and the first slider 21 is provided with a first stopper 24 for limiting the stroke of the first tunnel slider 22, and the movable mold is provided with a second stopper 26 for limiting the stroke of the first slider 21. A spring 27 is provided between the first slider 21 and the first tunnel slider 22. The first slider 21 is provided with a first tunnel hole 21a, and the first tunnel slider 22 is provided with a first insert 23 facing the side of the cavity, and the first insert 23 extends into the first tunnel hole 21a when the mold is closed.

[0043] Furthermore, a slider plate is installed on the second slider 31, and the first slider 21 and the first tunnel slider 22 are both slidably matched with the slider plate, wherein the first tunnel slider 22 is closer to the fixed mold than the first slider 21. When the mold is opened, the movable mold and the fixed mold are separated from each other, and the inclined guide column 25 on the fixed mold first drives the first tunnel slider 22 to move, and the first tunnel slider 22 laterally pulls out the first insert 23 as the core, providing a space for deformation for the forced release between the first joint 11 and the first slider 21. After that, the first tunnel slider 22 abuts against the first stopper 24, and the inclined guide column 25 continues to move to drive the first slider 21 to move, and the first slider 21 and the first tunnel slider 22 move synchronously, so that the first joint 11 is forced to be released from the first tunnel hole 21a on the first slider 21.

[0044] Specifically, combined Figure 10-13 As shown, in this embodiment, the second lateral core-pulling mechanism 3 includes a core-pulling actuator 34, which acts on the second tunnel slider 32 and drives the second tunnel slider 32 to move linearly. The second tunnel slider 32 is connected to the second slider by a pull rod 37. The second slider 31 is fixedly mounted with a plurality of guide rods 36, and the second tunnel slider 32 is slidably matched with the guide rods 36. The second slider 31 is provided with a second tunnel hole 31a, and the second tunnel slider 32 is provided with a second insert 33 facing the side of the cavity, and the second insert 33 extends into the second tunnel hole 31a when the mold is closed.

[0045] Furthermore, in this embodiment, a slider seat 35 is fixedly mounted on the movable mold, and the second slider 31 and the second tunnel slider 32 are both slidably mounted on the slider seat 35. The core-pulling actuator 34 is a core-pulling cylinder, and its piston rod end is fixedly connected to the second tunnel slider 32, which is used to drive the second tunnel slider 32 to perform linear motion. After the movable mold and the outer side of the fixed mold are opened, the first joint 11 is demolded, and then the core-pulling actuator 34 drives the second tunnel slider 32 to move outward, driving the second insert 33 on the second tunnel slider 32 to move outward synchronously, and the second insert 33 as the core is separated from the inner hole of the second joint 12, providing a space for deformation for the forced separation between the second joint 12 and the second slider 31. Afterwards, the second tunnel slider 32 drives the second slider 31 to move through the pull rod 37, so that the second joint 12 is forced out of the second tunnel hole 31a on the second slider 31.

[0046] Furthermore, the second tunnel slider 32 is provided with a through hole corresponding to the guide rod 36 , and the guide rod 36 is slidably matched with the through hole.
