Description

Technical Field

[0001] This utility model relates to a high-efficiency semi-solid forming equipment for metal doors. Background Technology

[0002] The applicant's previous authorized patent, publication number CN210647786U, disclosed a semi-solid high-efficiency extrusion molding equipment for aluminum door processing, including a track, multiple lower dies, a frame, a hydraulic cylinder mounted on the frame, and an upper die fixed on the piston rod of the hydraulic cylinder. The track has multiple semi-circular convex strips evenly spaced along the track axis in the middle. Multiple heat-insulating electric heating rods are also provided on the track between each pair of convex strips. The multiple heat-insulating electric heating rods are set in a reflector. Each heat-insulating electric heating rod extends from the beginning of the track to the bottom of the frame. The bottom of the lower die has multiple limiting parts corresponding to the convex strips. The bottom of the limiting parts has an arc-shaped groove. Multiple pairs of telescopic rollers are also provided on the bottom of the lower die on both sides of the arc-shaped groove. Each end of the lower die has a connecting end. Each pair of lower dies is connected by a chain. A sleeve is also fitted on the chain. It has the advantage of high processing efficiency.

[0003] However, in the above-mentioned equipment, the heating element that plays a heating role is set on a track, and the distance between the heating element and the lower mold is not adjustable. This will result in an excessively large distance between the heating element and the lower mold before the mold is closed, resulting in a large amount of heat being wasted. When the mold is closed, the insufficient distance between the heating element and the lower mold will delay the cooling and forming of the semi-solid metal in the lower mold. In addition, the heating element in the above-mentioned structure is often exposed to the outside environment, which is not only a waste of heat but also easily damaged. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a high-efficiency semi-solid forming device for metal doors that can reduce heat waste and prevent damage to the heating tube.

[0005] The technical solution of this utility model is: a high-efficiency semi-solid forming equipment for metal doors, including multiple lower molds that are displaced along a track, wherein the lower mold is composed of a base, an upper seat and a lower mold fixed on the top of the upper seat;

[0006] A heating frame is vertically connected between the base and the upper seat. The heating frame consists of a frame body and multiple heating tubes evenly spaced within the frame body. The base is provided with multiple support platforms, each of which is positioned to correspond to the gap between two heating tubes. The top of each support platform abuts against the upper seat. Multiple guide rods are fixed on the frame body. The upper seat has multiple guide holes corresponding to each guide rod. The upper end of each guide rod passes through the corresponding guide hole, and the lower end of each guide rod passes through the frame body and inserts into the clearance hole on the base. Springs are also fitted onto each guide rod between the frame body and the base.

[0007] The base and the upper seat are fixed together.

[0008] Furthermore, the bottom of the upper seat is provided with a corresponding clearance groove for the heating frame. When the heating frame is not compressed and lowered, the upper end of each heating tube is located in the clearance groove.

[0009] Furthermore, multiple liner plates are provided in the frame below each heating tube, and a heat-reflecting layer is provided on the top of each liner plate.

[0010] Furthermore, each of the aforementioned support platforms is also provided with a heat-reflecting layer on both sides.

[0011] Furthermore, a wall panel is provided at each of the front and rear ends of the base, the height of the wall panel is the same as the height of the support platform, and the tops of the two wall panels abut against the front and rear ends of the bottom of the upper seat, respectively.

[0012] Furthermore, the upper seat is provided with connecting platforms on both outer sides, and the base and the connecting platforms are connected by multiple connecting columns.

[0013] Furthermore, each of the guide rods is provided with an elastic cap at its top. When the upper mold and the lower mold are closed, the edge of the upper mold presses against the cap.

[0014] Furthermore, the connection between the guide rod and the top of the frame also has a truncated cone, and the bottom shape of the guide hole corresponds to the truncated cone.

[0015] Furthermore, the bottom of the base is also provided with a slider corresponding to the track.

[0016] Furthermore, the base is provided with connecting parts at both the front and rear ends, and the connecting parts of the two bases are connected together.

[0017] The beneficial effects of this utility model are as follows: The heating tubes of this utility model are built into the lower mold and move with the displacement of the lower mold, making them less prone to damage; when the upper mold is not closed with the lower mold, the heating frame is in a raised state under the action of each spring, and each heating tube is set close to the upper seat to heat and keep the semi-solid metal in the lower mold, making full use of thermal energy; when the upper mold and the lower mold are closed, the edge of the upper mold abuts against the top of each guide rod and presses down, causing the heating frame to move down away from the bottom of the upper seat, which on the one hand accelerates the cooling and shaping of the solid metal in the lower mold plate, and on the other hand avoids the possible deformation of the upper seat that may cause the heating tubes to be squeezed and damaged; finally, the base supports the upper seat through multiple support platforms, and each heating tube moves up and down between the support platforms, so the base still has a relatively reliable support for the upper seat and will not affect the normal closing of the upper and lower molds.

[0022] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0023] Combination Figure 1-3 As shown, a high-efficiency semi-solid forming device for metal doors includes multiple lower molds that are displaced along a track. The lower molds are composed of a base 1, an upper seat 2, and a lower mold 3 fixed to the top of the upper seat 2.

[0024] A heating frame is vertically connected between the base 1 and the upper seat 2. The heating frame consists of a frame 4 and multiple heating tubes 5 arranged at equal intervals within the frame 4. The base 1 is provided with multiple support platforms 6, each of which is set to correspond to the gap between every two heating tubes 5. The top of each support platform 6 abuts against the upper seat 2. Multiple guide rods 7 are fixed on the frame 4. The upper seat 2 has multiple guide holes corresponding to each guide rod 7. The upper end of each guide rod 7 passes through the corresponding guide hole, and the lower end of each guide rod 7 passes through the frame 4 and is inserted into the clearance hole 8 on the base 1. A spring 9 is also fitted on each guide rod 7 between the frame 4 and the base 1.

[0025] The base 1 and the upper seat 2 are fixed together.

[0026] The working principle and beneficial effects of the above structure are as follows: The heating tube 5 of the above structure is built into the lower mold and moves with the displacement of the lower mold, making it less prone to damage; when the upper mold is not closed with the lower mold, the heating frame is in a raised state under the action of each spring 9, and each heating tube 5 is set close to the upper seat 2 to heat and keep the semi-solid metal in the lower mold 3 warm; when the upper mold and the lower mold are closed, the edge of the upper mold abuts against the top of each guide rod 7 and presses down, causing the heating frame to move down away from the bottom of the upper seat 2, which on the one hand accelerates the cooling and shaping of the solid metal in the lower mold 3, and on the other hand avoids the possible deformation of the upper seat 2 that may cause the heating tube 5 to be squeezed and damaged; finally, the base 1 supports the upper seat 2 through multiple support platforms 6, and each heating tube 5 moves up and down between each support platform 6, so the base 1 still has a relatively reliable support for the upper seat 2 and will not affect the normal closing of the upper mold and the lower mold.

[0027] In another embodiment, combined Figure 1 and Figure 2 As shown, the bottom of the upper seat 2 is provided with a corresponding relief groove 10 for the heating frame. When the heating frame is not pressed down, the upper end of each heating tube 5 is located in the relief groove 10. In this way, the heating frame and the upper seat 2 cooperate to put each heating tube 5 in a relatively closed space, so as to better heat the upper seat 2 and reduce heat loss.

[0028] In another embodiment, combined Figure 1 and Figure 2 As shown, multiple liner plates 11 are provided inside the frame 4 below each heating tube 5, and a heat-reflecting layer is provided on the top of each liner plate 11.

[0029] In another embodiment, each of the support platforms 6 is also provided with a heat-reflecting layer on both sides to work with the liner 11 to reflect the heat of the heating tube 5 to the upper seat 2.

[0030] In another embodiment, such as Figure 3 As shown, a wall panel 12 is provided at the front and rear ends of the base 1, and the height of the wall panel 12 is the same as the height of the support platform 6. The tops of the two wall panels 12 respectively abut against the front and rear ends of the bottom of the upper seat 2 to ensure the support effect of the base 1 on the upper seat 2.

[0031] In another embodiment, such as Figure 1-3 As shown, the upper seat 2 is provided with connecting platforms 13 on both outer sides, and the base 1 and the connecting platforms 13 are connected by multiple connecting columns 14.

[0032] In another embodiment, combined Figure 1 and Figure 2 As shown, each of the guide rods 7 is also provided with an elastic cap 15 at its top. When the upper mold and the lower mold are closed, the edge of the upper mold presses against the cap 15.

[0033] In another embodiment, combined Figure 1 and Figure 2 As shown, the connection between the guide rod 7 and the top of the frame 4 also has a truncated cone 16. The bottom shape of the guide hole corresponds to the truncated cone 16 to improve the strength of this part of the guide rod 7 and prevent the guide rod 7 from twisting.

[0034] In another embodiment, the bottom of the base 1 is also provided with a slider corresponding to the track.

[0035] In another embodiment, the front and rear ends of the base 1 are respectively provided with connecting parts, and the connecting parts of the front and rear bases 1 are connected together.
