Description

Technical Field

[0001] The invention relates to the technical field of compression molding dies, and in particular to a stacked, expandable and efficient compression molding die. Background Art

[0002] Conventional molds require at least two upper and lower molds, namely a female mold and a male mold. A set of female and male molds can produce one product. At the same time, a set of equipment is required for molding, which increases the equipment occupancy rate and cannot flexibly adjust the number of moldings each time. If multiple sets of female and male molds are used for molding at the same time, the equipment table needs to be increased, which further increases the requirements for the equipment. High temperature and high pressure are usually required during molding, so the unit cost of the equipment is usually high, which is not conducive to cost reduction and efficiency improvement. The combined array type female and male mold structure is to process multiple cavities in the female mold or the male mold to mold multiple sets of products at one time, but the mold processing efficiency is low, most of which need to rely on machine tools for milling, and cannot be quickly processed by turning, and the structure is complex.

[0003] Therefore, there is an urgent need for a stacked, expandable and efficient molding die that can effectively improve production efficiency and simplify the structure. Summary of the invention

[0029] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0030] refer to Figure 1-2 The specific embodiment of the present invention provides a stacked, expandable and efficient molding die, comprising:

[0031] A mold 1, wherein a plurality of molds 1 are placed vertically in sequence and installed on a molding device, wherein the plurality of molds 1 are opened in sequence from top to bottom or closed in sequence from bottom to top;

[0032] The male mold 3 is arranged on the bottom surface of the mold 1;

[0033] The female mold 4 is arranged on the top surface of the mold 1, and the male mold 3 of the vertically adjacent mold 1 is correspondingly arranged above the female mold 4;

[0034] A cavity is formed between the male mold 3 and the female mold 4, and the product 2 is formed in the cavity.

[0035] Conventional molds require at least two upper and lower molds, namely, a female mold and a male mold. A set of female and male molds can produce a product. At the same time, a set of equipment is required during molding, which increases the occupancy rate of the equipment and cannot flexibly adjust the number of moldings each time. If multiple sets of female and male molds are used for molding at the same time, the equipment table needs to be increased, which further increases the requirements for the equipment. High temperature and high pressure are usually required during molding, so the single cost of the equipment is usually high, which is not conducive to cost reduction and efficiency improvement. The combined array type female and male mold structure belongs to processing multiple cavities in the female mold or the male mold, and molding multiple sets of products at one time, but the processing efficiency of the mold is low, and most of them need to rely on machine tools for milling, and cannot be processed quickly by lathe. In this application, several groups of molds 1 are installed vertically, and the product 2 is molded between the vertically adjacent molds 1. The number of molds 1 can be increased or decreased according to production needs; specifically, when the top of the mold 1 is set as the female mold 4 and the bottom is set as the male mold 3, when the upper and lower adjacent molds 1 are closed, the product 2 is molded between the male mold 3 and the female mold 4. Compared with a set of male and female molds, this application is produced by vertical stacking, which effectively improves production efficiency. Only molds 1 of the same size need to be produced, which is easy to replace, improving both production efficiency and maintenance efficiency. Compared with the combined array-type male and female molds, this application does not require additional equipment, and does not need to consider the position and matching relationship of each product cavity that needs to be considered in the array-type mold, and the design is relatively simple.

[0036] Further optimization plans also include:

[0037] The rebound structure is installed between vertically adjacent molds 1. The vertically adjacent rebound structures are alternately arranged in the horizontal direction. A plurality of molds 1 are closed from top to bottom or opened from bottom to top in sequence through a plurality of rebound structures.

[0038] The main purpose of the alternating arrangement is to avoid structural interference between adjacent springback structures, which would affect the mold closing or mold opening effect; the main function of the springback structure is to realize the opening of several molds 1 from top to bottom, or the closing of several molds 1 from bottom to top.

[0039] To further optimize the solution, the rebound structure includes:

[0040] A guide rod 7, which is vertically fixedly connected to the mold 1 located below and extends into the bottom of the mold 1 located above;

[0041] The spring 6 is in contact between the top end of the guide rod 7 and the mold 1 located above.

[0042] When the vertically adjacent molds 1 are in the mold closing state, the spring 6 is in the compressed state under the action of the molding device; when the mold is opened, the force of the molding device on the mold 1 is gradually reduced, and the vertically adjacent molds 1 are opened under the rebound action of the spring 6. The molding device can also assist the mold 1 in opening the mold, reducing the consumption of the spring 6. Among them, the main function of the guide rod 7 is to ensure the stability of the mold 1 during the vertical movement.

[0043] Further optimization plans also include:

[0044] The first circular hole 5 is opened on the bottom surface of the mold 1 located above, the top of the guide rod 7 is vertically slidably connected in the first circular hole 5, and the spring 6 abuts between the top of the guide rod 7 and the bottom wall of the first circular hole 5.

[0045] Further optimization plans also include:

[0046] A fixed sleeve 8, which is fixedly connected to the bottom of the mold 1 located above, has the same inner diameter as the first circular hole 5, and is sleeved on the circumference of the guide rod 7;

[0047] The second circular hole 9 is opened on the mold 1 located below, the bottom of the guide rod 7 is fixedly connected to the bottom wall of the second circular hole 9, and the outer peripheral side of the fixing sleeve 8 is vertically slidably connected in the second circular hole 9.

[0048] The function of the fixing sleeve 8 is, on the one hand, to increase the stability of the movement of the upper and lower molds 1 , and on the other hand, to increase the movement stroke of the upper and lower molds 1 .

[0049] According to a further optimized solution, a gap is provided between the fixing sleeve 8 and the bottom wall of the second circular hole 9 .

[0050] The main function of setting the gap is to set the margin, so that when closing the mold, the upper and lower molds 1 are in contact first to avoid affecting the closing effect.

[0051] According to a further optimized solution, the outer diameter of the top end of the guide rod 7 is smaller than the inner diameter of the bottom end of the fixing sleeve 8 .

[0052] The main function of such arrangement is to prevent the guide rod 7 from being separated from the fixing sleeve 8, that is, to prevent the mold opening distance between the upper and lower molds 1 from being too large.

[0053] According to a further optimization scheme, the elastic force of all springs 6 in the plurality of rebound structures decreases sequentially from bottom to top.

[0054] All springs 6 are arranged vertically in a collinear manner, based on the principle that the smaller the elastic force of the spring 6, the earlier it is compressed and the later it rebounds, while the larger the elastic force, the later it is compressed and the earlier it rebounds; when the mold is started to be closed, under the pressure of the molding equipment, the mold 1 at the top is closed first (the topmost spring 6 is compressed first), and then the molds are closed downwards in sequence; when the mold is opened, the mold 1 at the bottom is opened first (the bottommost spring 6 rebounds first), and then the molds are opened upwards in sequence.
