Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a mold demolding structure. Background Technology

[0002] Molds are various products used in industrial production to obtain desired products through methods such as injection molding, blow molding, extrusion, die casting, forging, smelting, and stamping.

[0003] Some molds require the use of angled ejectors and secondary demolding to eject the product. In existing technology, angled ejector molds with secondary demolding often use springs, such as nitrogen springs. However, using springs for secondary demolding has the problem that the springs may lose their elasticity after long-term use due to excessive demolding force, resulting in a shorter mold life. Utility Model Content

[0004] In view of this, the present invention addresses the deficiencies of the existing technology, and its main purpose is to provide a mold demolding structure that solves the problem of short mold service life.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a mold demolding structure, having a first state and a second state, including,

[0006] The mold body is equipped with a drive mechanism;

[0007] The sliding mechanism is driven by a drive mechanism to move the sliding mechanism away from or towards the product. The sliding mechanism has a positioning part and a contact surface that contacts the product.

[0008] The ejection mechanism includes an inclined ejector, the outer surface of which is exposed to the contact surface; and a connecting member is provided between the ejection mechanism and the sliding mechanism.

[0009] In the first state, one end of the connector is connected to the mold body and the other end is connected to the ejector mechanism, causing the ejector mechanism to remain stationary. The driving mechanism drives the sliding mechanism away from the product, and the angled ejector pushes the product away from the contact surface. When the positioning part reaches the connection position with the connector, one end of the connector is connected to the ejector mechanism and the other end is connected to the positioning part, causing the sliding mechanism to connect with the ejector mechanism. The mold switches to the second state, and the driving mechanism drives the sliding mechanism and the ejector mechanism away from the product, so that the angled ejector disengages from the product.

[0010] In one embodiment, the positioning mechanism includes a first positioning block, a second positioning block, a third positioning block, and a control rod; the outer surface of the second positioning block is recessed with a mounting cavity, and the inclined top is rotatably disposed in the mounting cavity;

[0011] The first row block covers the opening of the mounting cavity and is fixedly connected to the second row block, with the contact surface located on the outer surface of the first row block; one end of the third row block is connected to the driving mechanism, and the other end is connected to the inner surface of the second row block;

[0012] One end of the control rod is connected to the inner surface of the second positioning block, and the positioning part is provided on the side of the control rod near the ejection mechanism.

[0013] In one embodiment, the ejection mechanism includes an inclined ejector, an ejector plate, and an ejector rod. The ejector plate is disposed in the mounting cavity. One end of the inclined ejector is rotatably disposed on the ejector plate via a rotating shaft. One end of the ejector rod passes through a second positioning block and is connected to the ejector plate. The other end of the ejector rod is provided with a through hole, and the connector is disposed in the through hole.

[0014] In one embodiment, the connector is a pin with pointed ends, and the positioning part is a first positioning pin hole; the mold body is provided with a positioning block, and the positioning block is provided with a second positioning pin hole.

[0015] In the first state, the upper end of the pin is inserted into the second positioning pin hole, and the lower end passes through the through hole and abuts against the upper surface of the control rod, and the control rod can slide along the lower surface of the pin; in the second state, the lower end of the pin falls into the first positioning pin hole, and the upper end of the pin disengages from the second positioning pin hole and is embedded in the through hole, so that the push rod and the control rod are connected.

[0016] In one embodiment, the driving mechanism is a hydraulic cylinder, and the output shaft of the hydraulic cylinder is connected to the sliding mechanism.

[0017] In one embodiment, the product is a vehicle refrigerator, and the inner side of the vehicle refrigerator has a slot protruding inward at one end, and the ejector end of the sloping top has a molded part that matches the slot on the corresponding end face.

[0018] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution:

[0019] In the first state, one end of the connector is connected to the mold body and the other end is connected to the ejector mechanism, causing the ejector mechanism to remain stationary. The driving mechanism drives the sliding mechanism away from the product, and the angled ejector pushes the product away from the contact surface. When the positioning part reaches the connection position with the connector, one end of the connector is connected to the ejector mechanism and the other end is connected to the positioning part, causing the sliding mechanism to connect with the ejector mechanism. The mold switches to the second state, and the driving mechanism drives the sliding mechanism and the ejector mechanism away from the product, so that the angled ejector disengages from the product. By replacing the traditional spring demolding structure with a mechanical demolding structure, the service life of the mold is greatly improved.

[0038] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0041] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0042] Please see Figures 1 to 5 As shown, this application provides a mold demolding structure having a first state and a second state, including a mold body 10, a driving mechanism 11, a sliding mechanism 20, and a positioning part 201 and a contact surface 202 that contacts the product 1. The driving mechanism 11 drives the sliding mechanism 20 away from or towards the product 1. The sliding mechanism 20 has an ejection mechanism 30, including a slanted ejector 31, the outer surface of which exposes the contact surface; and a connecting member 40 is provided between the ejection mechanism and the sliding mechanism.

[0043] In the first state, one end of the connector 40 is connected to the mold body 10, and the other end is connected to the ejector mechanism 30, causing the ejector mechanism 30 to remain stationary; the drive mechanism 11 drives the sliding mechanism 20 away from the product, and the angled ejector 31 pushes the product away from the contact surface. When the positioning part 201 reaches the position where it is connected to the connector 40, one end of the connector 40 is connected to the ejector mechanism 30, and the other end is connected to the positioning part 201, causing the sliding mechanism 20 to connect with the ejector mechanism 30. The mold switches to the second state, and the drive mechanism 11 drives the sliding mechanism 20 and the ejector mechanism 30 away from the product 1, so that the angled ejector 31 disengages from the product.

[0044] By using a mechanical secondary demolding structure instead of the traditional spring secondary demolding structure, the service life of the mold is greatly improved.

[0045] In the initial state, the outer surface of the inclined ejector 31 is flush with the contact surface 202, and the outer surface of the inclined ejector can be considered as part of the contact surface. In the first state, the drive mechanism 11 drives the sliding mechanism 20 away from the product. Since the inclined ejector 31 does not move with the sliding mechanism 20 at this time, the inclined ejector 31 will extend out of the contact surface 202 and push the product 1 away from the contact surface. Under the action of the sliding mechanism 20, the inclined ejector 31 rotates downward at a certain angle, causing the latching position of the inclined ejector to disengage from the product. In the second state, the sliding mechanism 20 and the ejection mechanism 30 move away from the product simultaneously, causing the inclined ejector to completely disengage from the product.

[0046] In one embodiment, the positioning mechanism includes a first positioning block 21, a second positioning block 22, a third positioning block 23, and a control rod 24; the outer surface of the second positioning block 22 is recessed with a mounting cavity 221, and the inclined top 31 is rotatably disposed in the mounting cavity 221.

[0047] The first row block 21 covers the opening of the mounting cavity 221 and is fixedly connected to the second row block 22. The contact surface 202 is located on the outer surface of the first row block 21. One end of the third row block 23 is connected to the driving mechanism 11, and the other end is connected to the inner surface of the second row block 22.

[0048] One end of the control lever 24 is connected to the inner surface of the second row block 23, and the positioning part 201 is provided on the side of the control lever 24 near the ejection mechanism 30. Optionally, the first row block 21, the second row block 22, the third row block 23 and the control lever 24 can be locked together with screws.

[0049] In one embodiment, the ejection mechanism 30 includes an inclined ejector 31, an ejector plate 32, and an ejector rod 33. The ejector plate 32 is disposed in the mounting cavity 221. One end of the inclined ejector 31 is rotatably disposed on the ejector plate 32 via a rotating shaft. One end of the ejector rod 33 passes through the second positioning block 23 and is connected to the ejector plate 32. The other end of the ejector rod 33 is provided with a through hole 331, and the connector 40 is disposed in the through hole 331.

[0050] By rotatably mounting the inclined ejector 31 on the ejector plate 32, in the first state, the first positioning block 21 moves away from the product, the inclined ejector 31 extends out of the contact surface 202, and under the action of the first positioning block 21, rotates downward around the rotation point by a certain angle.

[0051] In one embodiment, the connector 40 is a pin 40, the upper and lower ends of the pin 40 are pointed, the positioning part 201 is a first positioning pin hole 201; the mold body 10 is provided with a positioning block 12, and the positioning block is provided with a second positioning pin hole 121.

[0052] In the first state, the upper end of the pin 40 is inserted into the second positioning pin hole 121, and the lower end passes through the through hole 331 and abuts against the upper surface of the control rod 24. The control rod 24 can slide along the lower surface of the pin. At this time, the pin 40 and the control rod 24 are not connected together. In the second state, the lower end of the pin 40 falls into the first positioning pin hole 201, and the upper end of the pin 40 disengages from the second positioning pin hole 121 and is embedded in the through hole 331, so that the ejector rod 33 and the control rod 24 are connected, thereby connecting the sliding mechanism 20 and the ejection mechanism 30 together for secondary demolding.

[0053] Through the ingenious design of the combination of pin 40, through hole 331, first positioning pin hole and second positioning pin hole, the mold can be demolded to a specified distance in one go and then mechanically demolded a second time. The structure is simple and ingenious and very practical.

[0054] In one embodiment, the drive mechanism 11 is a hydraulic cylinder, and the output shaft of the hydraulic cylinder is connected to the sliding mechanism 20. Of course, the drive mechanism 11 can also be a pneumatic cylinder, a motor, or anything else that can provide power to the sliding mechanism.

[0055] The product 1 is a vehicle refrigerator 1. One end of the inner side of the vehicle refrigerator 1 is provided with a slot 101 protruding inward. The ejector end 311 of the inclined top 31 is provided with a forming part that matches the slot on the corresponding end face.

[0056] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
