Description

Technical Field

[0001] This utility model relates to the field of forming molds, and in particular to a lifting rod forming mold. Background Technology

[0002] When manufacturing lifting rods, a molding mold is used. The existing molding mold includes a top mold and a bottom mold. During manufacturing, the top mold and the bottom mold are simply put together, and then casting can be performed. The existing molding mold has a simple structure and is convenient to use. However, certain defects have been found in its production. That is, it can generally only produce one type of product and cannot be adapted to the characteristics of each product. In order to solve the above problems, the existing lifting rod molding mold needs to be improved. Utility Model Content

[0003] The purpose of this utility model is to provide a lifting rod forming mold to solve the problem of poor adaptability of existing lifting rod forming molds.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A lifting rod forming mold includes a bottom mold and a top mold. The top surface of the bottom mold has a lower forming groove adapted to the lower half of the lifting rod, and the bottom surface of the top mold has an upper forming groove adapted to the upper half of the lifting rod. After the bottom mold and the top mold are closed, the upper forming groove and the lower forming groove together form a lifting rod forming cavity. The lifting rod forming cavity includes a handle section, a horizontal section, an inclined section and an end section arranged sequentially. The inner side of the connection between the handle section and the horizontal section, and the outer side of the inclined section and the end section are provided with insertion positioning structures. The bottom mold is assembled and fixed by bottom mold blocks, and the bottom mold blocks include a handle section bottom module, a horizontal section bottom module, an inclined section bottom module and an end section bottom module. The top mold is assembled by top mold blocks, and the top mold blocks include a handle section top module, a horizontal section top module, an inclined section top module and an end section top module.

[0006] In this solution, the original integrated template structure has been changed to a detachable split structure. This allows for the selection and combination of split structures of different sizes according to the required product model. This enables adaptive adjustments based on the characteristics of the product, allowing for more flexible production of lifting rods. The plug-in positioning structure ensures better fit between the top and bottom templates, resulting in fewer defects in the produced lifting rods.

[0007] As a further preferred embodiment of this utility model, the transitions between the horizontal segment and the inclined segment, and between the inclined segment and the end segment, are all arc-shaped.

[0008] This transition is smoother.

[0009] As a further preferred embodiment of this utility model, the inner side of the curved structure of the end section is also provided with a plug-in positioning structure.

[0010] Positioning at three points can further reduce the fit error between the top and bottom templates, and also makes it less likely for the bottom and top templates to shift during production.

[0011] As a further preferred embodiment of this utility model, the insertion positioning structure includes an insertion short post and a sleeve ring. The insertion short post is vertically arranged on the top surface of the bottom template, and the sleeve ring is arranged on the bottom surface of the top template corresponding to the insertion short post. The sleeve ring is adapted to the insertion short post.

[0012] As a further preferred embodiment of this utility model, the bottom template blocks and the top template blocks are detachably connected by screw connectors. Each screw connector includes an upper screw through hole, a lower screw through hole, an upper screw, a lower screw, and a connecting nut. The upper screw through hole is horizontally opened at the top of the bottom template block or the top template block, and the lower screw through hole is horizontally opened at the bottom of the bottom template block or the top template block. The upper screw and the lower screw are respectively inserted through the upper screw through hole and the lower screw through hole, and the connecting nut is threaded to both ends of the upper screw and the lower screw.

[0013] The screw connector has a simple structure. After it is fixed, the connection between the bottom template blocks and the top template blocks is tight and can be pressed by the nuts at both ends, so that liquid will not leak out from the gaps during casting.

[0014] As a further preferred embodiment of this utility model, the top of the top template is also provided with a lifting handle, and there are four connecting posts between the lifting handle and the top template. The positions of the four connecting posts correspond to the four top template blocks respectively. The top of the connecting posts is rotatably connected to the lifting handle, and the bottom of the connecting posts is threadedly connected to the top template blocks.

[0015] Easy to demold.

[0016] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0017] 1. In this solution, the original integrated template structure has been changed to a detachable split structure. This allows for the selection and combination of split structures of different sizes according to the required product model. This enables adaptive adjustments based on the characteristics of the product, allowing for more flexible production of lifting rods. The plug-in positioning structure ensures better fit between the top and bottom templates, resulting in fewer defects in the produced lifting rods.

[0018] 2. Positioning at three points can further reduce the fit error between the top and bottom templates, and it is also less likely for the bottom and top templates to shift during production.

[0019] 3. The screw connector has a simple structure. After it is fixed, the connection between the bottom template blocks and the top template blocks is tight and can be pressed by the nuts at both ends, so that liquid will not flow out from the gaps during casting. Attached Figure Description
