Description

Technical Field

[0001] This utility model relates to the field of molding machine technology, and in particular to an integrated sand-shooting structure. Background Technology

[0002] When the molding machine compacts the sand mold, it needs to use a certain number of hydraulic cylinders, sometimes dozens of hydraulic cylinders are needed for compaction, thus forming a multi-contact hydraulic cylinder structure. The multi-contact hydraulic cylinder structure is connected to the integrated structure, and under the control of the control valve, it compacts the sand in the sand box structure located below the integrated structure.

[0003] The applicant has discovered at least the following technical problems in the prior art: the existing integrated structure only has a multi-contact hydraulic cylinder structure, and the molding machine also needs to set up a separate sand inlet structure from the outside of the integrated structure and the sand box structure. The structure is relatively complex, occupies a lot of space, affects the structural layout, and the shadow of such sand inlet structure is relatively large, resulting in poor sand inlet effect. Utility Model Content

[0004] The purpose of this utility model is to provide an integrated sand-shooting structure to solve the technical problems existing in the prior art. The preferred technical solutions among the various technical solutions provided by this utility model and their numerous technical effects are detailed below.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An integrated sand-shooting structure includes an integrated unit, a multi-contact hydraulic cylinder unit, and an auxiliary sand-shooting unit. The multi-contact hydraulic cylinder unit and the auxiliary sand-shooting unit are both disposed on the integrated unit. The outlet of the auxiliary sand-shooting unit forms a sand inlet, through which sand can enter the sand box structure.

[0007] Preferably, the auxiliary sand-shooting unit includes an auxiliary sand-shooting component, which is disposed through the integrated unit. A sand-inlet channel is formed inside the auxiliary sand-shooting component, and the sand-inlet is formed at the outlet of the sand-inlet channel.

[0008] Preferably, the cross-sectional area of ​​the top of the sand inlet channel is larger than the cross-sectional area of ​​the sand inlet.

[0009] Preferably, the number of auxiliary sand-shooting elements is at least one.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] In the description of this utility model, it should be understood that the terms "center," "side," "length," "width," "height," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and "side," etc., indicate the orientation or positional relationship based on the appendix. Figure 1 The orientations or positional relationships shown are for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0026] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0027] Reference Figures 1 to 3 This utility model provides an integrated sand-shooting structure, including an integrated unit 1, a multi-contact hydraulic cylinder unit 2, and an auxiliary sand-shooting unit 3. The multi-contact hydraulic cylinder unit 2 and the auxiliary sand-shooting unit 3 are both mounted on the integrated unit 1. The outlet of the auxiliary sand-shooting unit 3 forms a sand inlet 311, through which sand can enter the sand box structure.

[0028] By integrating a multi-contact hydraulic cylinder unit 2 and an auxiliary sand-shooting unit 3 on the integrated unit 1, while maintaining the compaction operation of the multi-contact hydraulic cylinder unit 2, sand can directly enter the sand box structure through the sand inlet 311 on the auxiliary sand-shooting unit 3. There is no need to set up a separate sand inlet structure outside the integrated unit 1. Therefore, the overall structure is simplified, more concise, and the structural layout is optimized, saving space and effectively improving the sand-shooting effect.

[0029] As an optional implementation, the auxiliary sand-shooting unit 3 includes an auxiliary sand-shooting component 31, which is disposed through the integrated unit 1. A sand-inlet channel is formed inside the auxiliary sand-shooting component 31, and a sand-inlet 311 is formed at the outlet of the sand-inlet channel.

[0030] In this embodiment, the shape of the sand inlet 311 is not specifically limited. It can be a square, rectangle, polygon, circle, ellipse, or other irregular shapes. In actual application, it can be flexibly selected and set according to actual usage needs. In the attached drawings of this embodiment, the display effect when the shape of the sand inlet 311 is rectangular is preferably shown.

[0031] As an optional implementation, the cross-sectional area of ​​the top of the sand inlet channel is larger than the cross-sectional area of ​​the sand inlet 311. This arrangement can accelerate the flow rate of the sand, allowing the sand to enter the sand box structure more quickly from the sand inlet 311.

[0032] As an optional implementation, the number of auxiliary sand-shooting elements 31 is at least one. In this embodiment, there is no specific limitation on the number of auxiliary sand-shooting elements 31. In actual application, the number can be flexibly selected and set according to actual usage needs. As the number of auxiliary sand-shooting elements 31 increases, the efficiency of sand flowing into the sand box structure may increase, but it will also be related to the size of the sand inlet 311.

[0033] Furthermore, when there is only one auxiliary sand-shooting component 31, its spatial positional relationship with the multi-contact cylinder unit 2 is not specifically limited. It only needs to be staggered in space to ensure that no collision occurs. The specific setting position of the auxiliary sand-shooting component 31 can be flexibly adjusted according to actual usage requirements. It can be located on one side of the multi-contact cylinder unit 2 or at a certain position among several individual cylinders 21 of the multi-contact cylinder unit 2.

[0034] Furthermore, when there are multiple auxiliary sand-shooting components 31, the spatial positional relationship between all the auxiliary sand-shooting components 31 and the multi-contact cylinder unit 2 is not specifically limited. They only need to be staggered in space to ensure that no collision occurs. The specific setting position of multiple auxiliary sand-shooting components 31 can be flexibly adjusted according to actual usage requirements. For example, all the auxiliary sand-shooting components 31 can be located on one side of the multi-contact cylinder unit 2, or they can be located entirely on the periphery of the multi-contact cylinder unit 2, or they can be located entirely in a certain position among several individual cylinders 21 of the multi-contact cylinder unit 2, or some can be located in a certain position among several individual cylinders 21 of the multi-contact cylinder unit 2 and the rest can be located on the outside of several individual cylinders 21 of the multi-contact cylinder unit 2.

[0035] The accompanying drawings of this embodiment preferably show the effect of having four auxiliary sand-shooting elements 31. The four auxiliary sand-shooting elements 31 are arranged around the periphery of the multi-contact hydraulic cylinder unit 2, which can make the most of the space structure and achieve a reasonable layout.

[0036] As an optional implementation, the multi-contact cylinder unit 2 includes several individual cylinders 21. The top of the individual cylinder 21 is connected to the integrated unit 1 and its bottom can move relative to the integrated unit 1. The individual cylinder 21 compacts the sand inside the sand box structure through the relative movement of its bottom with the integrated unit 1.

[0037] As an optional implementation, all the individual hydraulic cylinders 21 are arranged in an array. The array arrangement makes the individual hydraulic cylinders 21 more evenly distributed, thereby forming a uniformly distributed multi-contact head that covers the entire working area of ​​the compaction operation and can effectively complete various compaction operations.

[0038] As an optional implementation, the integrated unit 1 includes an integrated plate 11 and a compaction plate 12. The compaction plate 12 is connected to the bottom of the integrated plate 11, and the top of the individual hydraulic cylinder 21 is connected to the integrated plate 11. The integrated plate 11 can integrate and connect all the individual hydraulic cylinders 21. The bottom of the individual hydraulic cylinder 21 extends out of the compaction plate 12 and moves relative to the compaction plate 12.

[0039] As an optional implementation, the integrated unit 1 also includes a pressure block 13. Each individual hydraulic cylinder 21 is detachably connected to a pressure block 13 at its bottom. The pressure block 13 can move synchronously with the bottom of the individual hydraulic cylinder 21. The pressure block 13 and the individual hydraulic cylinder 21 are preferably connected by bolts. When the individual hydraulic cylinder 21 is working, the pressure block 13 is located at the bottom of the individual hydraulic cylinder 21 and will make actual squeezing contact with the sand. In this embodiment, the shape of the pressure block 13 is not specifically limited and can be any required shape. It can be flexibly selected and set according to actual usage requirements.

[0040] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
