Description

Technical Field

[0001] The invention relates to a device for molding some plastic materials, in particular to a double-guide-pillar plastic material molding machine. Background Art

[0002] At present, for some plastic materials in mass production, they are often formed by special forming equipment. This type of forming equipment is mainly suitable for factories, and its purchase cost and use cost are also high. For some plastic materials in small batch production, in most cases, they often need to be formed manually with the help of simple molds. Although there are some simple forming equipment on the market, they require high costs and are not conducive to promotion and use. As for pastry making in family workshops, at present, it is mainly through the use of molds to simply shape the blanks and then bake them. The quality depends on the level of labor. At the same time, this production method is labor-intensive and time-consuming, and the manufacturing cost cannot be effectively controlled. Therefore, how to design a forming equipment suitable for small-scale occasions such as family workshops has become an urgent need for the general public. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a double-guide-pillar plastic material forming machine with ingenious structural design, low manufacturing cost, simple and convenient operation, good use stability, high forming efficiency and good forming quality.

[0004] In order to solve the above technical problems, the double-guide column plastic material forming machine of the present invention includes a supporting base, a lower die base arranged on the supporting base, an upper die base capable of reciprocating relative to the lower die base, a driving support base arranged at the rear of the supporting base, and a guide support base vertically arranged on the driving support base. A driving screw driven by a transmission mechanism is arranged on the driving support base, and two guide rods arranged parallel to the driving screw are arranged between the top of the guide support base and the supporting base. The upper die base is respectively installed in cooperation with the driving screw and the two guide rods and can be lifted and lowered reciprocatingly along the guide rods under the drive of the driving screw. A molding plate adapted to the lower die base is fixedly installed on the upper die base. The molding plate can be reciprocated relative to the lower die base by lifting and lowering the upper die base to press the blank.

[0005] The cross-sectional shape of the driving support seat is an L-shaped structure, and the driving support seat is clamped and fixed on the rear part of the supporting base.

[0006] A placement cavity for accommodating a transmission mechanism is arranged at the rear of the driving support seat, and the transmission mechanism is arranged in the placement cavity.

[0007] A driving motor connected to the main shaft of the transmission mechanism is installed on the side of the driving support seat.

[0008] The transmission mechanism is a worm gear mechanism.

[0009] The guide support seat is composed of two vertical beams and a top plate connected to the top of the two vertical beams, and the guide rod is installed between the top plate of the guide support seat and the support base.

[0010] A limit switch capable of sensing the lifting position of the upper die base is installed between the two vertical beams.

[0011] The limit switch is connected between the two vertical beams by screws.

[0012] The lower die base is provided with at least one lower die groove.

[0013] The advantages of the present invention are: (1) By setting two guide rods located between the top of the guide support and the support base and arranged parallel to the driving screw, the upper die base can be installed in conjunction with the driving screw and the two guide rods respectively, so that it can be reciprocated and lifted along the guide rods under the drive of the driving screw. The guiding effect of the two guide rods is utilized to make the operation reliability and stability good during the pressing process, thereby greatly improving the pressing quality.

[0014] (2) The cross-sectional shape of the driving support seat is designed to be an L-shaped structure and the driving support seat is reliably fixed to the rear of the supporting base, so that the driving support seat and the supporting base are firmly installed as a whole and have good flatness, thereby ensuring the parallelism of the guide rod and the driving screw rod, further improving the pressing accuracy, and thus greatly improving the pressing quality.

[0015] (3) It only needs to assemble the support base, the lower die base, the upper die base, the driving support base, the guide support base, the guide rod and the driving screw rod. It is easy to manufacture, has a low manufacturing cost, is easy to operate and use, and has high efficiency.

[0016] (4) By directly providing a placement cavity for accommodating the transmission mechanism at the rear of the driving support seat, the transmission mechanism is directly placed in the placement cavity. The transmission method is simple and reliable, easy to maintain, and has a compact structure design and occupies little space.

DETAILED DESCRIPTION

[0019] The double-guide-pillar plastic material forming machine of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0020] like Figure 1-3 As shown, the double-guide column plastic material forming machine of the present invention includes a support base 1, a lower die base 2, an upper die base 3, a support base 1 driving support base 4 and a guide support base 5. The lower die base 2 is directly formed on the support base, and at least one lower die groove 17 is provided on the lower die base 2. The guide support base 5 is vertically arranged on the driving support base. The cross-sectional shape of the driving support base 4 is an L-shaped structure. The driving support base 4 is clamped and fixed to the rear part of the support base, thereby making its overall consistency good. A driving screw 6 driven by a transmission mechanism 9 is provided on the driving support base 4. Two guide rods 7 arranged parallel to the driving screw are provided between the top of the guide support base 5 and the support base 4. It can be seen from the figure that the guide rods 7 are respectively located on both sides of the driving screw. The upper die base 1 is respectively installed with the driving screw 6 and the two guide rods 7. Specifically, a mounting hole and two guide holes are provided on the upper die base 1. A rotating nut is screwed on the driving screw. The upper die base is connected to the rotating nut 16 as a whole through the mounting hole, and is installed respectively with the two guide rods and the two guide holes. After installation, the back side of the upper die base 1 contacts the front side of the guide support 5, thereby further improving the guiding accuracy. Through this structural design, the upper die base 1 can be reciprocated and lifted relative to the lower die base 2 along the guide rod under the drive of the driving screw. A die pressing plate 8 adapted to the lower die base is fixedly installed on the upper die base 3. The lifting of the upper die base 3 can make the die pressing plate reciprocate relative to the lower die base to press the blank.

[0021] Furthermore, the rear portion of the driving support seat 4 is provided with a placement cavity 10 for accommodating the transmission mechanism, and the transmission mechanism 9 is placed in the placement cavity. The side of the driving support seat 4 is installed with a driving motor 11 connected to the main shaft of the transmission mechanism 9. In this embodiment, the transmission mechanism 9 is preferably a worm gear mechanism.

[0022] Furthermore, the guide support 5 is composed of two vertical beams 12 and a top plate 13 connected to the top of the two vertical beams. The guide rod 7 is installed between the top plate of the guide support 5 and the support base 4. At the same time, the top plate 13 is a C-shaped structure, and the driving screw rod extends above the top plate through the C-shaped groove of the driving screw rod.

[0023] Furthermore, a limit switch 14 capable of sensing the lifting and lowering position of the upper mold base is installed between the two vertical beams 12. The limit switch is connected to the control circuit of the motor and is used to limit the upper and lower end points of the stroke of the upper mold base. The limit switch 14 is connected between the two vertical beams 12 by screws 15 and can adjust the installation position up and down to adjust the stroke of the upper mold base.
